How do we solve antibiotic resistance?

The looming danger of antibiotic resistance may have fallen out of the public consciousness but is still very much in the mind of those in public healthcare and research. As promising new research is published, the University of Birmingham’s Laura Piddock and GP Margaret McCartney get to the bottom of why antibiotic resistance is still so difficult to tackle. Marine biologist Helen Scales joins us in the studio to talk about her new book “What the Wild Sea Could Be” which uses changes in the Earth’s past to predict what we can expect to happen to our oceans in the coming years. Cosmologist Andrew Pontzen speculates on what happens in and around the extreme environment of a black hole as news of the first observations of the “plunging zone” comes to light. And as the EU head to ban smoky flavoured crisps we ask what the science behind this decision is with Food scientist Stuart Farrimond.

Why do we sleep?

Guest presented by Liz Bonnin.We all instinctively know that sleep is incredibly important but science doesn’t actually have a satisfying answer for why we need to sleep. There are multiple theories, but now, new research from Imperial College London has suggested that the leading idea might actually be incorrect. Science journalist Ginny Smith explains.Nearly 80 years ago, one of the rarest elements in the world, promethium, was first discovered, but it’s properties have only now been revealed. Andrea Sella, Professor of Chemistry at University College London, tells us what this means.What’s the scariest animal on the planet? Lions, crocodiles, or maybe tigers might come to mind. Yet a recent study has found that animals around the globe fear our voices far more than sounds of any other predators. Professor Liana Zanette explains how her research could help conservation efforts.Finally, we answer one of your questions. Listener Mary Evans got in touch to ask: ‘do you think it's likely that people who are widely travelled and used to eating local food and drinking tap water would have more diverse bacteria in their gut?’ Expert on all things microbiome, Megan Rossi, joins us in the studio to answer Mary’s query.

Micro Nuclear Reactors

Guest presented by Liz Bonnin. As the UK strives to achieve net zero by 2050, nuclear energy is looking more and more likely as a key player in reaching this goal. But it’s not just massive power plants like Hinkley point C - there’s are newer smaller reactors on the scene: small and micro modular reactors. 100 to 1000 times smaller than a conventional reactor, faster to build, and put together entirely in a factory before being shipped out, theoretically, anywhere: are micro modular reactors the future of nuclear energy or too good to be true? Dean of Engineering at the University of Liverpool, Eann Patterson, has just published a paper proposing a fleet of micro modular reactors to bear the burden of our energy load and he joins us to discuss the reality. What came first, the chicken or the egg? Science writer, broadcaster and now egg expert Jules Howard joins us to answer this age old question. His book Infinite Life tells the story of how the egg propelled evolution – whether it’s bird, insect, or mammal. This month, scientist Alexandra Freeman’s appointment to the House of Lords was announced. With a background in risk and evidence communication, Alexandra tells us why she applied, what she hopes to achieve, and how the public can get involved.

Is gene therapy the future?

Last week, a girl who was born deaf had her hearing restored following gene therapy. In the US, the first commercial gene therapy for sickle cell disease has just begun. And Great Ormond Street Hospital has found great success in their trials and a gene therapy for children lacking an immune system. Gene therapy is clearly having a moment. But how do these groundbreaking therapies actually work? And will they ever be truly accessible to everyone? Geneticist Professor Robin Lovell-Badge answers all. Also this week, atmospheric scientist Laura Wilcox answers an interesting listener question about the effect volcanoes can have on the weather and sticks around to dig into the connection between aerosols and weather in different regions. The exhibition “Bees: A Story of Survival” opened at the World Museum in Liverpool this month. Part of the show explains the how honeybees communicate through vibration. Physicist Martin Bencsik, who collected and studies these vibrations, plays us a few and explains their meaning. And did you get a chance to see the auroras that covered a large part of the Northern Hemisphere last weekend? The intense solar activity that caused them has some people alarm. Jim Al-Khalili, who has written a science fiction novel based on the concept, talks what is protecting us from solar flares and what could go wrong.

Is treated sewage worse for the environment than raw?

There has been increasing public outrage at raw sewage discharges into our rivers and seas, but new research at Lake Windermere suggests that treated sewage is as much to blame. Wastewater experts Simon Evans and Ali Morse get into the nitty gritty of sewage treatment and why it might be causing so many problems. Last week, the Sumatran orangutan Rakus made headlines when he was spotted by researchers treating a wound with a medicinal plant. A first for a wild animal. But he’s not the only animal to show self-medicating behaviour. Biologist and author of Wild Health, Cindy Engel, talks healing in the wild and what we can learn from the animals that do it. And it’s that time of year again: the Eurovision Song Contest. In fact, this year marks the 50th Anniversary since ABBA won the 1974 contest with the iconic track Waterloo. Psychology and behavioural researcher Harry Witchel tells us what gives songs at Eurovision a winning edge and tries to predict a winner based on his criteria.

Ugly animals and asteroid Apophis

One year ago, the World Health Organisation declared that COVID-19 would no longer be categorised as a global health emergency. But the pandemic has left us with a new normal in all areas of our lives. From vaccine rollout to wastewater monitoring, we’re asking: how has COVID altered the scientific landscape? Marnie Chesterton is joined in the studio by Linda Geddes, science journalist, and Barbara Kasprzyk-Hordern, Professor in Environmental and Analytical Chemistry at the University of Bath, to discuss.Are ugly animals getting the short end of the conservation stick? Whilst a few beautiful creatures, like tigers and panda bears, get good marketing and attract the most conservation efforts, comedian and biologist Simon Watt argues that the endangered animals which are less pleasing to the eye are being forgotten.Also this week, we answer a listener’s question about the accuracy of using bug splats on cars to measure insect populations. Lead data analyst from the Kent Wildlife Trust, Lawrence Ball, gives us the details about the national citizen science survey, Bugs Matter, which sees people around the country measure insect splats on vehicle number plates as a marker of insect abundance.And science journalist Roland Pease discusses the unprecedented scientific opportunity hurtling towards Earth in the form of asteroid Apophis. It will just miss our planet – in astronomical terms at least – but its proximity has astronomers excited.

Can we get plastic waste under control?

As the UN tries to get a global agreement on plastic waste we hear from two delegates at the conference in Ottawa; John Chweya, a Kenyan waste picker, and plastics scientist, Steve Fletcher, discuss the impacts of plastic pollution and the possible solutions. Taylor Swift’s new album, The Tortured Poets Department, exposes the pain a break up can cause. Heartbreak is a common theme in music and art – but what does science have to say about it? Florence Williams, science journalist and author of Heartbreak: A Personal and Scientific Journey, talks us through the research on what actually happens in our bodies when we go through a break-up. The nomadic Avar empire ruled over eastern and central Europe from the sixth to the ninth century but very little was known about them – until now. From studying ancient DNA, researchers have discovered a wealth of information about how the Avars lived. Dr Lara Cassidy, Assistant Professor in Genetics at Trinity College Dublin, explains the findings, and how it’s even possible to learn so much from ancient DNA. We all know how bees great are – but what about all the other pollinators? Dr Erica McAlister from the Natural History Museum in London speaks out in defence of the fly. Presenter: Victoria Gill Producers: Hannah Robins and Sophie Ormiston Editor: Martin Smith

Do we need a new model of cosmology?

Earlier this week, some of the world's leading astrophysicists came together at The Royal Society to question the very nature of our Universe. Does the Lambda Cold Dark Matter model, which explains the evolution of the cosmos and the Big Bang, need a rethink? Dr Chris North, an astrophysicist from the University of Cardiff, joins us in the studio to explain what this model says, and why it might need to be changed. The last few weeks seem to have been a non-stop cycle of depressing climate stories, with floods in Pakistan, mass coral bleaching and last month being the hottest March ever recorded. It's perhaps no surprise that many people are anxious about the news. Vic Gill is joined by Prof Lorraine Whitmarsh, an environmental psychologist at the University of Bath, and Tom Rivett Carnac, an author, political strategist and co-host of the podcast Outrage + Optimism. Together they discuss climate anxiety, and how to stay engaged with the news without feeling overwhelmed.And with all this wet weather, how are our precious insects faring? It turns out, bumblebees might have a trick up their fuzzy sleeves when the ground gets flooded - at least according to a new experiment led by Sabrina Rondeau from the University of Ottawa. We also get bumblebee expert Dave Goulson on the line to tell us more about these charismatic insects.

Bird flu outbreak in cows

A strain of highly pathogenic bird flu, H5N1, has been spreading unchecked through wild bird, and some mammal, populations for the past few years. Last week, news of a large number of dairy cows in the USA being infected with bird flu has alarmed the public and virologists alike. One farm worker has also picked up the virus and although they are not seriously ill, the jump between cattle and humans raises serious concerns over how the virus is moving and adapting. Virologist Dr Tom Peacock has the details. Also this week, thousands of eyes across America were turned to the skies to catch a glimpse of the total solar eclipse. But this event isn’t just a spectacle for the eyes – it’s a real scientific opportunity. Space physicist and electrical engineer Dr Nathaniel Frissell reveals his unusual approach to studying the eclipse via radio. And BBC reporter Georgina Rannard, who has been following the eclipse this week, tells Vic what other research scientists investigated during the four-minute window of darkness. And don’t turn your eyes away from the sky just yet, as another celestial spectacle is set to occur. About 3,000 light-years away, a pair of orbiting stars called T Coronae Borealis are not normally visible from Earth. But every 80 years or so, one of the stars in the binary system explodes, creating a ‘new’ star in our night sky. But you’ll only have a day or two to spot it. Astrophysicist Dr Rebecca Smethurst joins Vic in the studio to talk about this once-in-a-lifetime star explosion. And to close the show, the life and work of a legend. Nobel Prize-winning physicist Peter Higgs has died at the age of 94. Higgs’s biographer Professor Frank Close tells us how Higgs predicted the existence of a particle that’s fundamental to our understanding of the Universe and reveals the legacy he’s left behind.

200 years of dinosaur science

In 1824, 200 years ago, Megalosaurus was the first dinosaur to ever be described in a scientific paper. William Buckland studied fossils from Stonesfield in Oxfordshire in order to describe the animal. In this episode, Victoria Gill visits palaeontologist Dr Emma Nicholls at the Oxford University Museum of Natural History, who shows her those very fossils that launched the new science of palaeontology. Danielle Czerkaszyn then opens the archives to reveal the scientific illustrations of Megalosaurus by Mary Morland, which helped shape Buckland's description.But this was just the beginning. Over the coming decades, remains kept being discovered and scientists were gripped with dinosaur mania, racing to find species. Now, in 2024, we're finding new dinosaurs all the time. Victoria travels to the University of Edinburgh to meet Professor Steve Brusatte and Dr Tom Challands as they start extracting a dinosaur bone from a piece of Jurassic rock - could this be a new species? Together, they reflect on how palaeontology has changed over the last 200 years and ponder the ongoing mysteries of these charismatic animals.Presenter: Victoria Gill Producers: Alice Lipscombe-Southwell and Hannah Robins Production Co-ordinator: Jana Bennett-Holesworth  Editor: Martin Smith

Inside Your Microbiome

Microbiomes are a multi-million-pound industry. Every week, many people send off poop samples to be examined so we can learn about our own ecosystems of bacteria, virus and fungi that live in our guts, with a view to improving health. But how accurate are these tests? Microbiologist Prof Jacques Ravel is calling for better controls in what is currently an unregulated industry. He joins us along with Prof Tim Spector, scientific co-founder of personalised nutrition app ZOE, to discuss the areas of concern, and potential benefits, of this direct-to-consumer model. Nobel prize-winning psychologist Daniel Kahneman has died at the age of 90. Widely acknowledged as one of the world's most influential psychologists, his many years of study centred on how and why we make the decisions we do. In 2011, his book Thinking, Fast and Slow, which summarizes much of his research, was published and became a best seller. We’re joined by presenter and author Claudia Hammond to unpick his legacy. The price of lab monkeys has plummeted. Used for drug development and testing, their value skyrocketed during the vaccine development period of the pandemic. But when the boom for vaccines died, the demand for (and value of) these monkeys plunged. Journalist Eleanor Olcott provides the full picture.  Are there alternatives to animal testing? Marnie visits a lab in Cambridge to find out about neural organoids, cellular clumps grown from stem cells made to replicate the brain. Developmental biologist Prof Madeline Lancaster shows her around and Dr Sarah Chan from the University of Edinburgh digs into the ethics of this cutting-edge branch of science.Presenter: Marnie Chesterton Producers: Florian Bohr, Hannah Robins, Louise Orchard and Imaan Moin Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth  BBC Inside Science is produced in collaboration with the Open University.

Our Accidental Universe

Professor and presenter, Chris Lintott, talks about his new book Our Accidental Universe; a tour of chance encounters and human error in pursuit of asteroids, pulsars, radio waves, new stars and alien life. Even with incredible technological developments, the major astronomical events of the past century are largely down to plain ol’ good luck; discovered not, as you might assume, by careful experiment, but as surprises when we have been looking for something else entirely. For instance, the most promising habitat for life beyond Earth turns out to be Saturn's tiny moon Enceladus, whose oceans were revealed when NASA's Cassini probe did a drive-by and, we get the most from the Hubble Space Telescope by pointing it at absolutely nothing! A new company has launched which aims to mine Helium-3 on the moon to sell on Earth. This rare isotope is used for supercooling quantum computers and some scientists dream of using it in nuclear fusion as a new source of renewable energy. But is this ambition realistic and, if so, could it be within reach anytime soon? Planetary scientist Sara Russell of the Natural History Museum explains all. There are many moons in our solar systems, but one of the strangest is Titan; the largest moon of the Saturn system. It gets colder than -100 degrees Celsius and has a thick atmosphere that creates weather. But its biggest mystery is the enormous, coffee-coloured dunes that cover a large part of its surface. Where did they come from? Planetary scientist Bill Bottke has a cunning theory. In our universe, some stars are twins. They originate from the same molecular clouds and should be identical, but some pairs are not as similar as you’d expect. Marnie speaks to astrophysicist Yuan-Sen Ting about his new paper which illuminates how this difference might occur. His theory is that one of the stars, perhaps the evil twin, has been busy eating up vulnerable planets...  Presenter: Marnie Chesterton Producers: Louise Orchard, Florian Bohr and Imaan Moin Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth  BBC Inside Science is produced in collaboration with the Open University.

World’s oldest forest fossils

The world’s oldest fossilised forest was uncovered in Somerset last week. We head to palaeobotanist, Dr Christopher Berry’s, lab at Cardiff University to learn about these cladoxylopsids. They lived 390 million years ago and although they are not the ancestors of today’s trees, they reveal some extraordinary evolutionary secrets. Also, Marnie speaks to Dr Chris Thorogood of the University of Oxford Botanic Gardens about his new book Pathless Forest: The Quest to Save the World’s Largest Flowers. Called “Rafflesia” plants and found in the remotest parts of South East Asia, their flowers burst from the rain forest floor the size of pumpkins and are critically endangered. Chris talks of his world of extreme fieldwork and hair-raising expeditions, braving leeches, lizards and lethal forest swamps, to discover the rarest of rare blooms. Plus, the Wildlife Trust’s Making Friends with Molluscs campaign starts today, and I’m sure many gardeners will declare this an impossible task! We visit some allotments in Bristol to find out how people are managing slug and snail populations. And chat to Brian Eversham from the Trust of Bedfordshire, Cambridgeshire and Northamptonshire, who explains why these garden creatures should be considered our friends, not foes. And finally, Dr Stewart Husband from last week’s programme returns to answer more of your burning questions about your tap water.

How pure is the water from your tap?

A recent study on how to get rid of microplastics in water sparked presenter Marnie Chesterton’s curiosity. When she turns on the tap in her kitchen each day, what comes out is drinkable, clean water. But where did it come from, and what’s in it? Dr Stewart Husband from Sheffield University answers this and more, including listener questions from around the UK. Is water sterile? Should I use a filter? And why does my water smell like chlorine? Also, new research indicates that bumblebees can show each other how to solve puzzles too complex for them to learn on their own. Professor Lars Chittka put these clever insects to the test and found that they could learn through social interaction. How exactly did the experiment work, and what does this mean for our understanding of social insects? Reporter Hannah Fisher visits the bee lab at Queen Mary University in London. And finally, more than 20 million years ago, our branch of the tree of life lost its tail. At that point in time, apes split from another animal group, monkeys. Now, geneticist Dr Bo Xia at the Broad Institute of MIT and Harvard thinks he may have found the specific mutation that took our tails. Marnie speaks with evolutionary biologist Dr Tom Stubbs from the Open University about why being tail-less could be beneficial. What would a hypothetical parallel universe look like where humans roam the earth, tails intact? And what would these tails look like?

Dimming the Sun

Switzerland has submitted a proposal to create a United Nations expert group on solar geoengineering to inform governments and stakeholders. The idea was discussed at the UN Environment Assembly in Nairobi, Kenya, this week. Professor Aarti Gupta shares how, after tense negotiations, the different member states could not agree, and the proposal was withdrawn. Why is solar geoengineering a controversial issue? How would dimming the sun even work? And should we consider it a genuine option in our fight against climate change? Dr Pete Irvine and Professor Joanna Haigh join presenter Marnie Chesterton in the studio to discuss. Animal welfare charities have been celebrating a ban on donkey skin trade, agreed to this month by 55 African countries. This will make it illegal to slaughter donkeys for their skin across the continent, where around two thirds of the world’s 53 million donkeys live. Victoria Gill tells Marnie that the demand for the animals' skins is fuelled by the popularity of an ancient Chinese medicine called Ejiao, believed to have health-enhancing and youth-preserving properties and traditionally made from donkey hides. Lastly, Dr Jess Wade, physicist and science communicator at Imperial College London, discusses Breaking Through: My Life in Science. It’s the memoir of Nobel Prize-winning biochemist Dr Katalin Karikó, whose passion and dedication to mRNA research led to the development of the life-changing COVID mRNA vaccines.

Laboratory-Grown Meat

Professor Ben Garrod guest presents. As a new 'meaty rice' is created and Fortnum & Mason launch a scotch egg made with cultivated meat that they hope to have on sale as early as next year, we investigate the world of laboratory-grown meat. Mark Post made the first ever synthetic meat in 2012 to the tune of £200,000. He tells us how these lab-grown meats are made and how, he thinks, they could play an important role in reducing greenhouse gas emissions and feeding a growing population. Jenny Kleeman, author of Sex, Robots and Vegan Meat, is more sceptical, citing concerns over food security and if the public really want to eat this stuff. A stingray called Charlotte has become pregnant, despite there being no other stingrays in her tank at the Aquarium & Shark Lab in North Carolina. Marine biologist Dr Helen Scales considers how this may have happened. And cosmic minerologist Sara Russell from the Natural History Museum tells us how astronomers tracked and found a particularly unusual asteroid entering Earth’s atmosphere and what we might learn from it.  Presenter: Professor Ben Garrod Producers: Hannah Robins, Florian Bohr, Alice Lipscombe-Southwell and Jonathan Blackwell Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth  BBC Inside Science is produced in collaboration with the Open University.

The Gulf Stream’s tipping point

The Gulf Stream, also known as the Atlantic Meridional Overturning Circulation (AMOC), is essential to stable global climate, and the reason we have moderate temperatures in Northern Europe. Now, a new modelling study suggests that this circulation could, at some point, be at a tipping point and collapse. We hear from one of the minds behind the model, post-doctoral researcher René van Westen from Utrecht University. But how likely is it that this will actually happen in the real world? Presenter Victoria Gill speaks to Jonathan Bamber who cautions that a gulf stream collapse is not imminent, and that it may just weaken slowly over time. Every summer in the Hudson Bay, on the Eastern side of Arctic Canada, the sea ice melts and the region’s polar bears head inland. But that ice-free season is getting longer, depriving the bears of that frozen platform that they use to pounce on their favourite prey – seals. So what do the bears do all summer? Research Wildlife Biologist Karyn Rode shares how she and her colleagues put a collar with video cameras on 20 polar bears, and what it revealed about their lives. Is CERN finally going to get a gigantic new particle accelerator? Almost exactly one decade ago, Roland Pease reported from Switzerland about the very first meeting about the successor of the Large Hadron Collider which was used to discover the Higgs Boson. Now there’s an update to the story. Roland is back to tell Vic how far along CERN is with their plans, and how much more time and money it will take to build the Future Circular Collider. Lovers of certain famous, creamy French cheeses could be in for a bit of a shock. Camembert and Brie are facing extinction as we know them! The Centre National de la Recherche Scientifique (CNRS) in Paris has stated that, over the last 100 years, the food and farming industry has placed too much pressure on the production of these types of cheeses. Now, the fungus traditionally used to grow the famous, fluffy white rinds has been cloned to a point where the lack of diversity in its genetic makeup means it can no longer be reproduced. Turophiles must learn to appreciate more diversity of tastes, colours and textures to protect the cheeses’ future.

Ancient Roman writings revealed

As part of the Vesuvius Challenge, computer scientists have used machine learning to successfully reveal 2,000 characters from the Herculaneum scrolls. These artefacts were charred to a crisp following the eruption of Vesuvius in 79 AD. Papyrologist Federica Nicolardi has been translating the writings, and tells us what exactly has been deciphered. Following this week’s launch of NASA’s PACE satellite, NASA scientist Dr Susanne Craig tells us how the mission will be giving our planet a health check. Bird flu is still an issue. This month, scientists have reported that hundreds of penguin chicks have died from the virus in the Falklands. Meanwhile, in Argentina, avian flu has killed huge numbers of elephant seal pups. Professor Wendy Barclay, a virologist from Imperial College London, tells us more about the virus and how it can jump between species. Sunday 11th February is International Day of Women and Girls in Science. Physicist Dr Jess Wade, who has written hundreds of Wikipedia biographies of women and underrepresented scientists, reveals one of her favourite scientists that people haven’t heard of.

When brains and computers meet

Are cyborgs now reality? Elon Musk certainly thinks so. His company, Neuralink, has successfully implanted one of its wireless brain chips in a human. Although billed as a breakthrough, they’re not the first to do it. In fact, similar devices have already been implanted, all with the aim of connecting our brains to computers with the aim of tackling complex neurological conditions. Joining Inside Science is neuroscientist and author, Dean Burnett. In this episode, Dean helps to break down the technology behind the brain-computer interface and digs into the ethical implications. Plus, game changing smart technology gets a run out as Rugby Union’s Six Nations Championship kicks-off. This year, all players will be wearing “Smart Mouth Guards.” These are intelligent gum shields containing miniature gyroscopes, accelerometers and Bluetooth, which provide - with incredible accuracy - a measure of the magnitude and frequency of forces experienced by players. An athlete making their international debut in this competition could have their entire collision history mapped from now until retirement, providing invaluable information for training and treatments. Crucial not only for elite squads, but ultimately for community and schools rugby where the technology will eventually land, leading to a safer game. And finally, it turns out that we can actually understand chickens even if we’ve never met them before! After assessing a group of around 200 volunteers, a team at the University of Queensland has discovered that humans with no experience of chickens at all, could understand the birds’ calls of satisfaction, or frustration. The research has serious implications for what’s known as precision farming, an area of livestock farming with little, to no, human interaction that requires automated systems of welfare detection using sound recognition.

Hydrogen and the race to net zero

Hydrogen has long been touted as a potential wonder gas that could play a significant role in our race to net zero. Now, planning permission has been granted for the UK’s largest production hub of its kind, and one of the most advanced in the world. Located in Cheshire, it bills itself as a vital piece of Northwest England’s mission to help manufacturers in the region decarbonise their processes and support UK jobs. We speak to chemical engineer and the plant’s site manager, Richard Holden, and we also catch up with Mark Miodownik, Professor of Materials and Society at University College London, about hydrogen and our future energy economy. Almost 25 years ago, Dr Marc Lammers stumbled across a mystery. The humpback whale singing he was recording via an underwater microphone near the shore was quieter during the day than at night. But he wasn’t able to answer why. Many years later, a PhD student, Anke Kuegler, joined his research team and took on the task of uncovering what was really going on. Using multiple ways of listening to and tracking the whales, she found out that the singing humpbacks were moving off-shore during the day, and closer to shore at night. Part of the mystery was solved, but it raised an even bigger question: what is driving this behaviour? Plus, a recent study has shown that terrestrial hermit crabs around the world are using non-organic materials, like plastic bottle caps, as their homes. Professor Marta Szulkin and her team at the University of Warsaw looked through social media photographs and videos (known as iEcology, or Internet Ecology) to find evidence for this new behaviour. Marta has theories about why the crabs are doing this, but it will take many years of research to uncover the long-term effects on hermit crab populations and their evolutionary trajectory. And, resident materials expert, Mark Miodownik, chats to Viv about what we can, and cannot, solve about the global plastic emergency.

A New Volcanic Era?

As lava consumes homes on the Reykjavik Peninsula in Iceland, evacuated communities have been witnessing eruptions shifting and intensifying. We take a look at the latest science that’s helping teams on the ground accurately predict where the danger is coming from, helping people to stay safe. Our go-to volcanologist, Dr Evgenia Ilyinskaya, and her colleague, Professor Andrew Hooper, from the University of Leeds tell presenter Victoria about these new technological advancements, and ask the crucial question: are we entering a new millennium of volcanic activity in Iceland? When looking at clear ocean water, you might assume that, aside from fish and some algae, there isn’t much living in it. But Prof Carlos Duarte knows it is full of life. In fact, his new study shows just how many different microbes – bacteria, viruses & fungi – live in all parts of our ocean. He and his team at King Abdullah University of Science and Technology in Saudi Arabia have created the largest ocean genome catalogue to date. Prof Mark Blaxter from the Wellcome Sanger Institute joins us to discuss this new study, the benefits of hypothesis-free science, and why he believes cataloguing the code of life of all the species on earth is an important endeavour. And, lastly, an old dinosaur fossil in New Mexico has been re-examined. What was believed to be of the infamous Tyrannosaurus rex may have been a different species all along. But not all palaeontologists agree. How do scientists even tell a dinosaur species from a fossil? Prof Stephen Brusatte tells Vic that it’s all about comparing bones.

Understanding Flood Forecasting

When Lois Pryce arrived at her boat in Berkshire, the area was already completely flooded. The only way to get to it was via a small pontoon. She is one of many across the UK that have been affected by the current floods, and is very familiar with the flood warning system accessible to the public. But how exactly does this system work? What information is taken into account? Marnie Chesterton speaks to Dr Linda Speight about flood forecasting, and the delicate balance of when to send out flood alerts and warnings. Plus, a supersized spacecraft is launching this October. Europa Clipper will assess whether the most intriguing of Jupiter’s 95 moons is habitable, meaning, could it support life? The evidence is tantalising. Jenny Kampmeier, Science Systems Engineer at NASA’s Jet Propulsion Laboratory, tells us why Europa might be the second body in our solar system on which life could exist. And, if you’ve been procrastinating over the housework – or should we say, mousework? - take a leaf out of a little rodent’s book. Apparently, mice do like to keep things clean, but a video that went viral this week seemingly takes this idea to another level entirely! You may well have seen the footage of a Welsh mouse gathering up objects in a shed and placing them neatly inside a box, night after night. It’s certainly very cute - Tidy Mouse carrying out its mousekeeping..but what’s the scientific explanation behind this curious behaviour? Finally, how do exercise and video games affect cognitive performance? Professor Adrian Owen is launching a new experiment to find out and he needs your help.

Space Exploration

2024 is an exciting year for lunar exploration. For Inside Science this week Marnie Chesterton investigates the planned missions to the Moon over the next twelve months. It’s been more than fifty years since the last manned mission to the Moon was completed. But that’s about to change with NASA’s upcoming Artemis II mission. This will not only be the first manned lunar flyby of the Moon since 1972, but also the first mission to have a woman and person of colour on board. Reid Wiseman, Commander of the Artemis II manned mission explains more about the mission and even lets us into a few secrets about what culinary delights await astronauts in space. But it’s not just NASA going to the Moon in 2024. China’s Chang’e 6 mission is lifting off in May, aiming to collect samples of rock from the far side of the moon. Quentin Parker, Director of the Laboratory for Space Research at the University of Hong Kong has a unique insight into China’s mission and has been following progress.

12 days of Christmas - science version

Marnie Chesterton & Victoria Gill embark on a science-themed version of the classic Christmas song ‘The 12 Days of Christmas’ in this festive edition of BBC Inside Science. Twelve of the biggest moments of the year in science include discussion about a very special treefrog discovered in the Ecuadorian Andes. We also hear about two new promising drugs for Alzheimer’s disease. An astronomer and visualisation scientist tells us about three new sonifications of space data. There’s more on the discovery of a 476,000 year-old wooden structure found earlier this year in Zambia and how it has changed archaeologists' understanding of ancient human life. The year has also seen 5,000 new species discovered in a deep ocean abyssal plain. Saturn has 62 new moons and is now the planet with the most moons in our solar system. A report was published deeming 75% of UK rivers as posing a risk to human health. We gathered together experts from Natural Resources Wales, Cardiff University, Bangor University and the Wye and Usk Foundation who discussed why the help from citizen science is essential for their work. And a new record has been set which is really worrying scientists - the highest average global ocean surface temperature, which reached 20.98 degrees centigrade. Other notable moments from the year include: a Japanese twelve-legged robot, eighteen video-calling parrots, proposals for the 10km long Einstein telescope and the theory behind why one player in every football team views the world slightly differently. To help us along the journey the BBC’s Radio Drama Company put all the science together into a brand-new rendition of the well-known 12 days of Christmas song.

The Science of the South Pole

We’re on board the RSS Sir David Attenborough for the vessel’s first big science season in the Antarctic, since it launched in 2020. It’s crewed by scientists involved in Project Biopole, a 5-year mission attempting to better understand carbon cycle at the poles. Nadine Johnston, a microbiologist with the British Antarctic Survey, joins Inside Science to talk about her work on copepods; zooplankton that build up huge fat reserves over the spring and summer months, then hibernate at 3000m during winter, taking carbon with them which is then locked-up in the deep ocean for up to 600yrs! Her research is a world first in the Southern Ocean and could help improve global carbon modelling of the earth system. Staying in the South Pole, neuroscientist John-Antoine Libourel, talks about his latest research into the surprising sleeping habits of chinstrap penguins. And after weeks of intense earthquake activity, the volcano on the Reykjanes peninsula of south-west Iceland has erupted. Dr Evgenia Ilyinskaya, our go-to volcanologist, provides an update. Plus, a nod to the festive season, as composer and AI artist, LJ Rich, explains why Christmas music makes us feel all fuzzy.

Biggest COP in history

COP 28, the largest climate summit in history, has drawn to a close. Marnie Chesterton examines some of the main stories to emerge from this lengthy conference. The way we look after our oceans, measures needed to ensure food security and an agreement to transition away from fossil fuel dependence were some of the big themes of the summit. The BBC’s climate reporter Georgina Rannard takes us through the final agreement. We hear from Glada Lahn, senior research fellow at international affairs think-tank Chatham House, who explains how we might one day wean ourselves off so-called ‘brown energy’. Farming is also a source of greenhouse gases. Growing, processing and packaging food account for a third of all greenhouse gas emissions. How we feed the 8.1 billion of us on the planet continues to be a contentious issue. Casper Chater from Royal Botanic Gardens Kew explains what we can do to adapt our existing crops to cope with more frequent flood and drought events. Oceans are warming, losing oxygen and acidifying. Sea levels are rising. We speak to Ko Barrett, a senior climate advisor at the US's National Oceanic and Atmospheric Administration, about the role oceans have played so far in helping us mitigate the worse effects of climate change. And we meet Mervina Paueli, a 25-year-old Tuvaluan negotiator, whose small archipelago in the South Pacific is on the frontline.

Vagrant Birds

Vagrant birds are those that appear in locations where they are not usually found. They might have been blown off course by a storm or have been affected by changing weather patterns due to climate change. Although a treat for birders, these visitors can also have a big impact on their new environments as Victoria Gill finds out when she heads to Burton Mere Wetlands on the Dee Estuary with Dr Alexander Lees, reader in biodiversity at Manchester Metropolitan University.As former Prime Minister Boris Johnson gives his testimony, we hear the latest from the UK Covid-19 Public Inquiry with BBC Health Reporter Jim Reed. A new study reveals that, contrary to a commonly-held view, the brain does not have the ability to rewire itself to compensate for the loss of, for example sight, an amputation or stroke. This is despite what most scientists believe and teach. Moreover, the assumption that it has this ability has led to all manner of erroneous treatments for amputees, stroke victims and other conditions, the study suggests. We’re joined by the study’s authors, Professor John Krakauer from Johns Hopkins University and Professor Tamar Making of the University of Cambridge. We’ll also hear from one of Tamar’s key case studies, Kirsty Mason, an amputee from the age of 18 who advanced the scientists’ experiments exponentially.   Presenter: Victoria Gill Producers: Hannah Robins and Louise Orchard Editor: Richard Collings Production Co-ordinator: Jana Bennett-Holesworth  BBC Inside Science is produced in collaboration with the Open University.

Loss and damages for vulnerable countries

Professor Saleemul Huq, director of the International Centre for Climate Change and Development in Bangladesh, has died. He was instrumental in pushing for a loss and damages fund for vulnerable countries affected by climate change. Last year’s COP27 climate conference made a pledge to set up this fund. But, as yet, there is not one in place. Marnie Chesterton speaks to BBC climate reporter Esme Stallard about Professor Huq’s legacy, and where the money will come from for a loss and damages fund. We also hear about an unusual snail that’s looking for love, with the help of matchmaking academic Dr Angus Davison. He’s hoping to find a suitor for the mollusc. Marnie talks to Lev Parikian, author of Taking Flight: The Evolutionary Story of Life on the Wing, which has been shortlisted for this year’s Royal Society Trivedi Science Book Prize.

Forever chemicals

PFAS chemicals, also known as forever chemicals, don’t break down in the environment. They can accumulate in the body and are found to have an array of harmful effects on human health. A major mapping project has revealed worryingly high levels of PFAS across thousands of sites in the UK. Experts are concerned that not enough is being done to reduce these chemicals from drinking water. They’re urging the government to re-evaluate current regulation. This week we dive into the properties of these chemicals: how dangerous are they and what can be done to protect public health? Professor Crispin Halsall, an environmental chemist from Lancaster University, tells us more. As charges are brought against four people for stealing and selling on US$1 million of dinosaur bones, we find out about the illegal – and legal – trade in fossils from palaeontologist Professor Steve Brusatte. New research has discovered the Moon is 40 million years older than we previously thought. Professor Sara Russell, a cosmic mineralogist and planetary scientist from the Natural History Museum, tells us more. And is there something we can we learn from animals about how to age better?

White phosphorus

White phosphorous is an incendiary material and if it were to be used in any built-up civilian areas, the practice would violate international law. We find out what makes white phosphorus so dangerous, and we ask how easy is it to identify? Andrea Sella, professor of chemistry at University College London, grants access to his laboratory and conducts an experiment with this highly flammable and volatile substance. Whole words and phrases from crushed and carbonised scrolls can be read for the first time in almost two thousand years. The documents, uncovered from Herculaneum, an ancient Roman town close to Pompeii which was buried under volcanic ash, have been made legible thanks to 3D scans and artificial intelligence. Dr. Federica Nicolardi, a papyrologist at the University of Naples, tells us more about this exciting discovery. Kate Zernike discusses her book The Exceptions, which tells the story of a group of 16 women who used their scientific know-how to inspire radical change. It’s been shortlisted for this year’s Royal Society Science Book Prize. And finally, this month marks exactly a year since beavers became a protected species in England.

Tumbling down the rabbit hole of assembly theory

A paper recently published in the journal Nature claimed that assembly theory could help explain and quantify selection and evolution. But what exactly is assembly theory? In this episode Marnie Chesterton speaks to science writer Philip Ball and zoologist and writer Professor Matthew Cobb. They dig into the science behind this tricky concept and figure out why it makes people so angry. A sample recovered by NASA from the Bennu asteroid hurtled back to earth recently. This week we saw what’s been retrieved from 200 million miles away. Studies on the dust and rock are just getting underway. Professor Tom Zega, one of the mission scientists, reveals why this sample will be important for many years to come. We also hear from Ed Yong who has been shortlisted for the Royal Society Trivedi Science Book Prize. He tells us about his book, An Immense World, where he encourages us to think beyond the confines of our fleshy bodies. People experience the world in many different ways. It all comes down to perception. We speak to Professor Fiona Macpherson who, along with neuroscientist Professor Anil Seth, are co-leads of The Perception Census which aims to document the differences.

Why is Prime Minister Rishi Sunak rowing back on climate pledges?

UK Prime Minister Rishi Sunak gave a hastily arranged press conference this week in which he confirmed he would be rowing back on some previously made government commitments regarding net zero - the point at which we remove as much carbon from the atmosphere as we put in. The reaction has been mixed, ranging from endorsements from fellow politicians in the Conservative Party to criticism from opposition parties and environmental groups. The business community is also split. So why has Mr Sunak changed his policies on climate change - and why now? Gaia Vince speaks to Ian Dunt, editor of We hear about an astonishing finding by archaeologists who have discovered expertly manufactured interlocking wooden structural parts that are half a million years old. What do they tell us about our early human ancestors in Africa? Gaia speaks to Professor of Archaeology Laurence Barham and Professor of Geography Geoff Duller about their extraordinary discovery. Approximately two billion tonnes of dust is lifted into the Earth’s atmosphere each year and it is both dangerous to human life and essential to the oxidisation of our oceans and rivers. We relentlessly attempt to rid our homes of dust but it always seems to come back. Why do we hardly ever discuss dust? A new book by Jay Owens, ‘Dust: The Modern World in a Trillion Particles’ does just that. Jay talks to Gaia about why we should we be as fascinated as she is by tiny airborne particles. As we emit CO2 into the atmosphere, a significant amount - around a third - is taken in by the oceans. With growing interest in carbon removal interventions, ocean scientist Dr David T. Ho tells Gaia about undertaking an exciting experiment. Listen to this bonus content in the podcast.

What makes a healthy river?

River health has captured the public imagination, particularly as overspills from sewers have been getting more attention in the media. But the condition of a river is so much more complicated than what flows into it from our water treatment systems. Agriculture, roads, how we use our drains, what we buy and even the medicines and drugs we take can all have an impact on our rivers and the plants and animals that call them home. So how are UK rivers doing? And what needs to happen to help those waterways that are drowning in pollution? Joining the BBC's Marnie Chesterton on stage at Green Man Festival in Wales to discuss all this is: Dave Johnston, team leader of environmental reporting at Natural Resources Wales, whose responsibility it is to monitor Welsh rivers. Joanne Cable, head of organisms and environment division at Cardiff University, whose focus is on biodiversity and what we at home can do to support our rivers. Simon Evans, chief executive of The Wye and Usk Foundation, who runs citizen science projects to support these two rivers local to the festival.

Battles with flames

We're in the heart of summer in Europe, where extreme heat has spiralled into out-of-control wildfires across the Mediterranean, leading thousands to flee their homes. Previously on Inside Science we've looked at how and why temperatures are soaring across the globe. Now we're homing in on one of the most visible effects of that. First, BBC climate and science reporter Georgina Rannard paints a picture of the link between these fires and climate change. Next up we hear from Professor Stefan Doerr, director of the Centre for Wildfire Research at Swansea University, on whether Europe is prepared for a future where these blazes are more frequent and intense. Another effect of climate change you might have heard about this week is the potential collapse of the Gulf Stream. Georgina explains why leading researchers have reservations about the science behind that claim. We investigate a sometimes overlooked and under-reported source of pollution: particles from vehicle tyres. Dr Marc Masen from Imperial College London tells us about the impact they’re having on our health. And pollution from tyres is affecting flora and fauna too. Dr Paul Donald, senior researcher at Birdlife International, explains how vehicles on our roads have impacted wildlife in the environment. Finally, from four wheels to two wheels! Geneticist and body weight scientist Dr Giles Yeo is cycling from Land's End to John O'Groats with two glucose monitors on his arm. He tells us what he's hoping to learn.

The wide-ranging effects of climate change

This week China hit a record high temperature, a scorching 52.2°C, while Death Valley in California measured 53.9°C. Elsewhere, Europe has been battling searing heat and raging wildfires. In previous editions of Inside Science we’ve explored the effects of heat on our health. This week we’ve zoomed out to get a wider perspective on the impacts of soaring temperatures. First up, Rebecca Tobi from the Food Foundation reveals how this weather will impact the range of foods we are used to seeing on supermarket shelves. Next we hear from Hayley Fowler, professor of climate change impacts at Newcastle University. She explains how the jet stream – which plays a large role in the UK’s weather – is affecting extreme weather patterns. Another country experiencing particularly extreme weather at the moment is China. BBC correspondent in Hong Kong, Danny Vincent, tells us how record temperatures could have wide-ranging effects beyond China’s borders. Changing heat patterns could even unlock new habitats for wildlife. Jo Lines, professor of malaria and vector biology at the London School of Hygiene & Tropical Medicine, says that we need to be aware of mosquito-borne diseases that could take hold in Europe. Then it’s off to Reading University, where reporter Harrison Lewis chats to meteorologist Dr Rob Thompson and senior researcher Dr Natalie Harvey, to find out more about how weather balloons can help with storm forecasting. Finally, we’re heading back to Trowbridge, near Bath, where Dr Stuart Farrimond explains exactly how our gardens can help in the battle against climate change.

How social media can affect the health of teenagers

The Threads social media app launched on 5th July. Instagram users were able to sign up with just a few clicks. It joins a plethora of other social media apps like Snapchat, Twitter and TikTok, all of which are readily accessible on our phones. With all these apps at our fingertips, it’s never been easier for us to discover new people to follow, keep in touch with our friends and stay up to date with the latest news about our favourite celebrities. But Professor Devi Sridhar, the chair of global public health at the University of Edinburgh, is concerned about the harmful effect that all these apps could potentially be having on the health of young people. She talks to Marnie Chesterton about why they should be better regulated in order to protect our children. Marnie is then joined by Professor Andrew Przybylski from the University of Oxford who says that more studies need to be carried out. Next up we find out more about phages – ‘good’ viruses that infect and destroy bacteria and could hold the key to fighting disease. Tom Ireland, author of a new book, The Good Virus, tells Marnie about the history of phages and their potentially exciting future. This week the European Court of Human Rights ruled in favour of middle-distance runner and Olympic champion Caster Semenya in a case related to testosterone levels in female athletes. Marnie speaks to developmental biologist Dr Emma Hilton about what causes differences in sexual development and the impact they can have. We also hear from Dr Stuart Farrimond who explains how the microclimates in your garden can affect the plants you can grow.

Mapping the universe

A rocket launch, super-massive black holes and ghost particles! This past week’s scientific findings are testament to how hard-at-work cosmologists and physicists have been seeking out the fundamental building blocks of our universe and the rules that govern it. Professor of Cosmology at UCL, Andrew Pontzen, joins Marnie Chesterton to discuss the lot of them. Euclid took to the stars on Saturday, carrying a wide-angle space telescope that promises the opportunity to create a far larger and accurate 3D map of the universe to anything ever seen before. Gravitational waves detected by the North American Nanohertz Observatory for Gravitational Waves (NANOgrav) provide insight into the role black holes play in galaxy formation. And neutrinos recorded in the remote ices of Antarctica have been detected from the centre of our Milky Way. Dr Stuart Farrimond also joins us for the next few weeks with his pitch on the science of gardening. He’ll be digging up facts and tips that will help make the most out of summer blooms. This week Stu unearths how the pH of your soil could be hindering the flowerbeds.And visit a Welsh quarry with reporter Ella Hubber to hear how a mere 462 million years ago new species were exploding onto the scene. Palaeontologists Dr Joe Botting and Dr Lucy Muir stumbled across the most abundant and rare deposit of soft bodied fossils on record, scoring an archaeological jackpot!

Heat and health

Last summer saw intense heatwaves across the world. And already this year, global air, surface and sea temperatures have hit the highest levels on record. China, India and the US are currently experiencing heatwaves. In June, the UK’s Met Office released a health warning because of the high temperatures. In this episode Gaia Vince investigates what causes heatwaves and how hotter weather impacts our health. She finds out how we can prepare ourselves as the temperatures rise. Gaia is joined by Peter Stott at the Met Office Centre for Climate Prediction, who reveals more about the forecast and what causes heatwaves. She also speaks to Bob Ward, policy director at the Grantham Research Institute on Climate and the Environment, who gives us the lowdown on the UK’s heat health warning system and says what the future could look like if we continue to miss climate targets. In addition, Dann Mitchell, professor of climate science at the University of Bristol, discusses the health impacts of extreme heat. Guillermo Rein, professor of fire science at Imperial College London, explains what sparks wildfires and how they spread. Elsewhere, Germany has launched a high-tech heat health warning system to warn people when the temperatures are rocketing. Gaia speaks to Andreas Matzarakis, from Albert Ludwig University in Freiburg, who developed the system.Presenter: Gaia Vince Producer: Harrison Lewis Content Producer: Alice Lipscombe-Southwell Assistant Producer: Robbie Wojciechowski Editor: Richard Collings

The science of sound

Scientists, conservationists and other researchers are using audio soundscapes in innovative ways to record the natural world in rich detail and help develop strategies to preserve it. Gaia Vince visits the Dear Earth exhibition at London’s Southbank Centre where she interacts with the ‘Tell It To The Birds’ artwork by Jenny Kendler. This piece transforms spoken word into birdsong, which Jenny hopes will help raise awareness of threatened species. She is joined by Dr Patricia Brekke from the Zoological Society of London who reveals more about the threats faced by birds. We then visit the Knepp Estate to meet ecologist Penny Green, who reveals more about the value of audio for her work. Gaia then speaks to Dr Alice Eldridge, an acoustics expert from the University of Sussex, who has spearheaded the Wilding Radio project at the Knepp Estate in Sussex. She was curious to find out whether the sounds in the environment would change following the introduction of beavers to the estate. In collaboration with arts cooperative Soundcamp, she built high-quality, solar-powered equipment to continuously broadcast the soundscape from above and below the water.While we can record animals which we currently share the world with, what about those that have been lost forever? Cheryl Tipp, the British Library’s curator of wildlife and environmental sounds, looks after the library’s audio collection of more than 250,000 species and habitat recordings. She shares the heartbreaking tale of a now-extinct bird and explains why sound is such a valuable resource. Finally, Dr Tim Lamont, a marine biologist from Lancaster University, tells us why a degraded coral reef sounds different from a healthy one. He explains how broadcasting the sounds of a healthy reef can help attract more marine wildlife to an area.Presenter: Gaia Vince Producer: Hannah Fisher Content Producer: Alice Lipscombe-Southwell Editor: Richard Collings

The Kakhovka dam and global food security

On Tuesday, the United Nations reported that the breach of the Nova Kakhovka dam on the Dnipro River in Ukraine will impact heavily on global food security, causing a rise in food prices and leaving many without access to clean drinking water. Nine days after the disaster Gaia looks to the future alongside Kira Rudyk, Ukrainian MP who is also leader of the opposition party Golos and Laura Wellesley, senior research fellow in the Environment and Society Programme at Chatham House.Earlier this week the three-year inquiry into COVID began, seeking ‘to examine the UK’s response to and impact of the COVID-19 pandemic and learn lessons for the future.’ Eyes are on the inquiry from many angles. Inside Science looks at what scientists hope to contribute and learn from it, with author and broadcaster Philip Ball.Also, a spike in North Atlantic sea temperatures has sparked concern among scientists. Richard Betts, head of climate impacts at the Met Office, talks through the factors that have coincided to form the anomaly.

An ocean of opportunities

For World Ocean Day, Gaia Vince finds out how the planet’s seas could help us to generate clean power, capture CO2 and feed the world. Gaia is joined in the studio by science journalist and marine biologist Olive Heffernan. She dives into the controversy regarding the potential of mining in deep oceans and discusses whether the seas could become the location for Industrial Revolution 2.0.We’re used to seeing seaweed wrapped around our sushi rolls but it’s so much more than that. As well as being a tasty addition to what we eat, seaweed plays a vital role in absorbing CO2. Gaia speaks to Vincent Doumeizel, a senior adviser on oceans to the UN Global Compact; he’s also the food programme director at the UK-based charity Lloyd’s Register Foundation. He’s confident that seaweed could enable us to sustainably feed a growing global population in the coming decades.Phytoplankton – microscopic species of algae that exist on the surface of the sea – also absorb huge amounts of carbon from the atmosphere. Sir David King, founder and chair of the Climate Crisis Advisory Group and former chief scientific adviser to the UK Government has the radical idea that artificial whale poo could boost phytoplankton growth, leading to an increase in fish stocks and, consequently, improved biodiversity in the oceans. He tells Gaia about his project and the potential it has for carbon capture.When we think of energy generation from the oceans, we tend to think of offshore technology such as wind turbines. But what about generating electricity using the water itself? Gaia speaks to Eco Wave Power’s Inna Braverman who reveals how her project harnesses the power of the waves by attaching to existing coastal structures such as piers and jetties, to provide a source of clean, renewable energy.

AI and human extinction

In the headlines this week eminent tech experts and public figures signed an open letter that read “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”One of the signatories was Geoffrey Hinton, the so-called ‘godfather of AI’. He’s become so concerned about the risks associated with artificial intelligence that he recently decided to quit his job at Google, where he had worked for more than a decade. But are these concerns justified, or is it overblown scaremongering? And should we start prepping for a Terminator-style takeover? To get the answers, presenter Gareth Mitchell is joined by computational linguist Prof Emily M. Bender from the University of Washington along with Dr Stephen Cave, Director at the Leverhulme Centre for the Future of Intelligence (CFI). Next up, we hear from Prof Carl Sayer at UCL, along with Dr Cicely Marshall and Dr Matthew Wilkinson from the University of Cambridge, to dig into the science behind wildflower meadows and whether they can boost biodiversity and even help ease climate change. Finally, have you heard about Balto the sled dog? He was part of a life-saving mission in the 1920s and now he has the chance to be a hero once more. His DNA has been studied by the Zoonomia project, which is using databases of genomes from hundreds of mammals to build a better picture of evolution. This data could then be used help identify those animals that are at the greatest risk of extinction.

The benefits and problems of eDNA

This week, we hear from the University of Florida’s Dr David Duffy. He heads up a team of researchers who are studying sea turtles. In order to track the animals and their diseases, the scientists devised a method of collecting fragments of DNA from tanks at the university’s turtle hospital, as well as from sand and water in the local environment. While they found plenty of turtle DNA, they were surprised to uncover large amounts of high-quality human eDNA. Duffy tells us all about the study and his surprising findings, but also highlights the ethical problems this could raise. We are then joined by Dr Matt Clark from the Natural History Museum, and Sir Jonathan Montgomery from University College London, to discuss the ins and outs of eDNA – how it can be beneficial for conservation, forensics and healthcare, but could also be problematic from a privacy perspective. Muriel Rabone and Dr Adrian Glover from the Natural History Museum have compiled an extensive checklist of all the species present in the remote Clarion-Clipperton Zone, which is an area twice the size of India, five kilometres deep in the Pacific Ocean. While you might expect this part of the sea to be devoid of life, the organisms that live there are surprisingly diverse, and we still know little about them. But the region is also chock-full of in-demand rare-earth metals. And we are joined by Dr Katie King to talk over some of her favourite science stories of the week, followed up by Helen Keen, who gets the kettle on to reveal more about the surprising physics behind a cup of coffee. Milk and two sugars for us, please. Presenter: Gareth Mitchell Producer: Hannah Fisher Content Producer: Alice Lipscombe-Southwell

Science in the making

The Royal Society is the oldest scientific academy in the world. Since being established in 1660, it has painstakingly archived thousands of papers, letters, manuscripts and illustrations from some of science’s most enquiring minds.In this episode, Victoria Gill takes a trip to the society to pore over some of the most intriguing artefacts within its vaults. While there, she finds out more about the formation of the Royal Society and how science has been shaped over the centuries. Along the way, she considers the role of women in science, and asks whether their contributions have been historically overlooked.She is joined by the Royal Society’s Louisiane Ferlier and Keith Moore, along with Prof Uta Frith, a Royal Society Fellow and psychologist, and Dr Stephen Webster, a senior lecturer in science communication at Imperial College London. As part of its Science in the Making project, the Royal Society is currently digitising all of its collections, for everyone to browse through and enjoy.

Can we prevent natural disasters?

Natural disasters such as earthquakes, tsunamis, volcanoes and hurricanes all have the power to cause deadly destruction. One event can lead to another, causing a chain reaction of devastation that can take years to rebuild from. But do all natural events have to turn into a disaster? Is there anything we can do to mitigate their impacts? Gaia Vince speaks to Anastasios Sextos, Professor of Earthquake Engineering at the University of Bristol to find out how we can engineer buildings to withstand earthquakes, and Bruce Malamud, Executive Director of the Institute of Hazard Risk and Resilience at Durham University, to learn how we can build models to forecast the risk of a natural disaster occurring. Lucy Easthope is a leading advisor on emergency planning and disaster recovery and a Professor in Hazard and Risk at Durham University. She joins Gaia in the studio to discuss her experience of being one of the first responders to disasters and how in fact, the way they unfold is more predictable than we might think. Ilan Kelman, Professor of Disasters and Health at UCL, also joins them to discuss the importance of social resilience, long-term planning and effective alert communication in managing and mitigating the aftermath of these events.

70th anniversary of the discovery of DNA’s structure

James Watson and Francis Crick, who detailed the double-helix structure of DNA in 1953, are perhaps two of the most iconic scientists of the 20th Century. Yet the story of how they made their incredible discovery is perhaps equally famous, with a notorious narrative suggesting that they only identified the structure after taking the work of Rosalind Franklin and using it without her permission. Now, 70 years after the discovery of DNA’s structure, it is perhaps time to rewrite the tale. New evidence has now been unearthed, in the form of an overlooked news article and an unpublished letter, that shows that Franklin was truly an equal contributor to the discovery, and Watson and Crick were not as malicious as previously assumed. Together with Matthew Cobb of the University of Manchester, Nathaniel Comfort from Johns Hopkins University, and Angela Creager of Princeton University, Gaia Vince discusses this tantalising tale and finds out more about how this discovery could bring a whole new twist to the story of DNA.

Rocket Launch Pollution

Whilst the globe struggles to shift to green sustainable energy sources, one industry has its sights set solely on the stars. Space X just launched the biggest rocket the world’s ever seen, and it won’t be their last even if it did end its test flight with a bang. As we enter a new golden age of space travel, Vic asks Associate Professor in Physical Geography Dr Eloise Marais if we are paying enough attention to the environmental impacts posed by a rapidly growing space industry. Have viruses, bacteria, and microorganisms influenced humanity more than we know? Author of new book, Pathogenesis: How Germs Made History, Dr Jonathan Kennedy discusses how germs and disease have shaped human evolution, history and culture and what we can learn from the COVID pandemic.

Covid – missing link found?

Data collated from swab samples taken in Wuhan’s market in the early days of the Covid pandemic suggest animals sold in the market were carrying the virus at the time. It’s the strongest evidence yet for an intermediate species – one which passed the virus on to humans after becoming infected by bats carrying the virus. Dr Florence Debarre from the Institute of ecology and environmental sciences, in Paris and Professor Eddie Holmes from Sydney University discuss the findings. Beethoven’s genome has been reconstructed from samples of his hair. It reveals some of his medical history, but also unexpected findings on his paternity. We discuss the ethics of such genetic analysis with Tom Booth who studies ancient DNA at the Francis Crick institute. And microbes may help us survive and thrive in space according to Astrobiologist Rosa Santomartino, not only that but their recycling capabilities could also help us on earth

Sweet Science

Researchers from London’s Francis Crick Institute have found a type of artificial sweetener is able to dampen down immune system responses - at least in mice. Karen Vousden and Fabio Zani tell us about the implications. And Ronan McCarthy from Brunel University has found a range of different artificial sweeteners have antibacterial properties. We discuss the connections between these two areas of research and the prospect of developing drug treatments from artificial sweeteners. Penny Johnes from Bristol University discusses the use of phosphorus in agriculture, it’s a key component of fertilisers, but global supplies may run out in a few years, despite this overuse of phosphorus in agriculture is also creating problems. And Chat GPT has had a makeover, a new version of the chatbot was rolled out this week. Chatbots seem to be getting a lot of press at the moment, but are they really something we will all be using in the future?

Science superpower?

The government has launched a new 10-point plan designed, it said to “cement the UK’s place as a global science and technology superpower”. We speak with Sir Paul Nurse, director of the Francis Crick Institute, for his take on the government's plan and the findings of his own review of the UK’s research landscape. In 1963, in a now famous speech at the Labour Party conference in Scarborough, Labour leader and soon to be Prime Minister Harold Wilson promised a new Britain would be forged in the “white heat" of a "scientific revolution". Nick Thomas Symonds, Labour MP and political biographer, discusses how that idea was put into action. Scientists in Bristol have published a detailed "future flood map" of Britain - simulating the impacts of flooding as climate change takes its toll. Paul Bates from Bristol University explains how the new flood risk maps give a level of detail that could help people to plan and adapt. Vic Gill visits the Calder Valley in West Yorkshire, a place that’s suffered repeated flooding in recent years, where the community is taking matters into its own hands. New fossil findings from China have led scientists to re-evaluate their classification of tiny tentacled sea creatures from half a billion years ago and declare that they are in fact seaweeds says Martin Smith, a paleobiologist from The University of Durham. And this re-classification isn't unusual, fossils are constantly re-examined in light of new evidence and insights. Susie Maidment a paleobiologist at the Natural History Museum takes us through some of her favourite contentious fossils.

Covid leaks and conspiracies

Science writer Philip Ball has followed the relationship between government and its scientific advisors throughout the pandemic. He discusses the role of scientific advisors in the light of conflicting information following the leak of a number of former Health Minister Matt Hancock’s WhatsApp messages. Phil tells us why he believes greater transpearency is needed around the advice offered to government. The head of the US FBI has suggested the Covid 19 pandemic may have been started through a leak from a laboratory. No evidence has been offered. The ‘lab leak ‘ theory is the counter idea to Covid having a natural origin. We hear from three scientists who have been to China to investigate different aspects of the virus origins story.Journalist and microbiologist Jane Qui visited the Wuhan Institute of Virology – the lab at the centre of the lab leak theory.Marion Koopmans from Erasmus University in Rotterdam was a member of the WHO mission to China to investigate the origins of Covid 19.And Eddie Holmes from the University of Sydney visited the market in Wuhan, the epicentre of the outbreak.Besides inflating party balloons helium gas has a vast range of industrial uses, particularly as a coolant. There’s a world shortage, and helium is only extracted with fossil fuels such as coal and methane gas. Earth scientist Anran Cheng at the University of Oxford has developed a method to look for helium deposits without the fossil fuel connection.And ever wondered how heavy all the animals in the world might be ?

Antarctic Ice Special

Sea ice coverage hit a recording-breaking low in the Antarctic this week, but what does this mean for the rest of the world? Why is the region so difficult to predict? And what could further changes in climate mean for the South Pole? Often the Arctic dominates conversations around polar warming but this week, with the help of climate modelling expert Tamsin Edwards, Kings College London, we’ll be tackling these questions and more. We’ll hear from British Antarctic Survey researcher Nadia Frontier, a marine biologist spending the summer at Rothera research base in the Antarctic. We join her as she traverses snow and ice to study the inhabitants of Adelaide island and the surrounding waters. Rachel Tilling from the Cryospheric Sciences Lab at NASA’s Goddard Space Flight Center helps us explore the continent from a different vantage point, explaining her work using satellite data to understand sea ice thickness.

Gene Editing Ethics, Killer Whale Mummy's Boys and Ancient Hippo Butchery

Chinese biophysicist He Jiankui caused international outrage when in 2018 when he used the gene-editing tool known as CRISPR Cas-9 to edit the genomes of two human embryos. That experiment, described by the Chinese Academy of Science and Technology described as ‘abominable’, resulted in the birth of twin girls. The experiment also landed Dr He in prison for three years. Now, out of prison and working for a company in Beijing that proclaims to offer “affordable gene therapy” – He Jiankui has been speaking in public. At an open bioethics event at the University of Kent last weekend, organisers invited the scientist to present his research and to face questions about his past experiments and his future plans. We spoke to event organiser Dr Joy Zhang about the reaction to event and to Professor Robin Lovell-Badge at the Crick Institute about the implications of CRISPR-CAS9 technology. A Hippo butchery site reveals that distant human ancestors have been using stone tools far longer than researchers previously thought. This archaeological site in Kenya revealed that ancient hominins Paranthropus have probably been using stone tools to prepare food and weapons since 2.9 million years ago. Professor Tom Plummer at Queens College, City University of New York take us through the discovery and what it reveals about hominin evolution. A study released this week reveals just how much of a burden sons are on killer whale mothers. Michael Wiess, research director at the centre for whale research, fills us in on their findings which are a product of nearly 40 years studying the southern resident Orca population. This long-term Whale census project began in the 70s, championed by researcher Ken Balcomb, who was passionate about understanding and protecting killer whales and who sadly passed away late last year. We hear from Ken and his team out on the water studying the southern residents, more of which can be found in BBC Radio 4 documentary The Whale Menopause.

Abundant energy

This week’s programme is a thought experiment: What would the world be like if energy became superabundant and very cheap?Energy is vital for every aspect of our society, and the energy cost of extraction, processing, manufacture and transport is priced into every product we buy. Today’s energy crisis is having a huge impact, from affecting diplomatic relations between nations to the availability of food. How can our energy systems evolve and what could cheap abundant energy mean for us, our relationship to the natural world, and each other?We discuss these issues and more with;Rachel Kyte CMG, Dean of The Fletcher School at Tufts University, who has previously worked for the UN on sustainability issues.Jim Watson, Professor of Energy Policy at UCL.

Exploring the New Environmental Improvement Plan

Defra, the department for Environment, food and Rural affairs, released its latest Environmental Improvement plan this week. Many environmental groups have criticised the plan for having vague commitments, and landowners are asking where the money is going to come from if say farmers are going to move land out of production and into conservation. For a view away from these vested interests we’ve turned to the Office of Environmental protection – the body set up after Britain left the EU to scrutinise government environmental policy. Chief Executive Dame Glenys Stacey, and Chief Insights Officer, Professor Robbie McDonald. Last week the UK passed an emergency exemption allowing sugar beet farmers to use a controversial neonicotinoid pesticide called Thiamethoxam. This is the third year in a row that the exemption has been in place and the decision came just days after the EU banned such exemptions across Europe. A discussion in parliament yesterday saw MPs criticise the move due to the impacts of neonicotinoids on already crashing Bees populations. We spoke to Dr Richard Gill at Imperial College London about exactly how these insecticides impact bees. There are volcanic islands dotted across the globe but exactly what caused their formation and how might they change in the future? Professor Ana Ferreira at University College London is a seismologist leading an ambitious study to measure deep vibrations and disturbances around volcanic islands in the Atlantic Ocean. She told us about the challenges of recording from the ocean floor and the other unexpected disturbances they detected. As humans our eyes are one of our most valuable and expressive social tools. The whites of our eyes or sclera enable us to follow each others gaze and look our for minute changes in mood, a feature that until recently was thought to be unique to humans setting us apart from animals in our ability to communicate. But Anthropologist Aaron Sandel at The University of Texas in Austin has noticed that white sclera is in fact present in one of our closest relatives; the chimpanzee.Presenter: Gaia Vince Producers: Julian Siddle and Emily Bird Inside Science is produced in Collaboration with the Open University

Towards Net Zero

Former Energy Minister Chris Skidmore’s report into Net Zero calls for ambitious policies to drive energy transition, framing it as a huge economic opportunity to drive national growth.Using and conserving energy in the home is one theme the report tackles. We discuss home insulation with Colm Britchfield , policy advisor at E3G. His recent report found those in some of the worst housing , in the private rented sector could save hundreds of pounds a year if their homes were properly insulated. But what is the incentive for landlords to pay for insulation?Electric heat pumps have been heralded as an alternative to gas boilers, but they are currently more expensive and finding an installer is not easy. Rebecca Dibb-Simkin from Octopus Energy tells us how they are working to make the technology more available.And what is the role of local authorities in the strive for net zero? We hear from Polly Billington, chief executive of UK 100 – a network of local government leaders committed to sustainability policies.How do you catch a poacher?

Chatbot plagiarism

ChatGPT (Generative Pre-trained Transformer) is an online conversational chatbot, launched by OpenAI in November 2022. To date it remains an online sensation, allowing users to generate poems, essays, code and images in seconds. But fear bubbles in academic circles that artificial intelligence could promote plagiarism in secondary and tertiary education. Technology writer and broadcaster Bill Thompson, and teacher of 20 years digital philosopher Rebecca Mace from University of West London suggest the news headlines may be sensationalising the impact this chatbot will have on student learning. The 1922 backbench committee on business, energy and industrial strategy is recommending free electricity for locals residing within 1 mile of onshore wind farms. Richard Black, senior associate at Energy and Climate Intelligence Unit, joins Marnie to discuss whether or not there is evidence of residents requiring incentives to accept renewable developments whilst governments strive to increase the implementation of green technologies.Do you tap your toes to Paul Simon or rock out to Led Zeppelin? Even if you have two left feet, your ability to recognise rhythm is unique in the animal kingdom.

The UK's first satellite launch

The UK's first satellite launch faced several delays in 2022, but Virgin Orbit's Cosmic Girl is prepped for imminent take off. BBC science correspondent Jonathan Amos has been following the activity in Newquay and, alongside Melissa Thorpe head of Spaceport Cornwall, describes the potential this launch has to promote and bolster the UK's space industry.Is laziness a particularly human trait? Apparently not according to Dr Daniella Rabaiotti from the Zoological Society of London. Her research shows many animals engage in behaviour akin to laziness even within groups where others might be very active. There’s evidence for this from animals as diverse as wolves, frogs and pheasants. Dani says it’s a factor worth considering in animal behaviour studies, simply are we biased towards the more active and outgoing animals as they are the ones we tend to see? Victoria Gill speaks to the founder and CEO of Nature Metrics Dr Cat Bruce and Katie Critchlow about the tools they use to help companies measure biodiversity at their worksites. From taking water or soil samples it’s possible to detect the DNA of a multitude of organisms from large animals down to microbes. The technique should help map the biodiversity of a given area and inform decisions on development and conservation. BBC Inside Science is produced in collaboration with the Open University

Killer smog

For a week at the beginning of December 1952, London was under a blanket of deadly smog. As a result, the Clean Air Act came into force a few years later banning smoky sulphurous fuels. However air pollution researchers are now concerned that rising emissions from wood burners may be undoing many of the gains from the Clean Air Act. We hear from Dr Gary Fuller, air pollution scientist at Imperial College London and author of The Invisible Killer, the Rising Global Threat of Air Pollution and How We can Fight Back. We also discuss emissions we can’t see, bacteria and even microplastics which are now present in the air.

One key issue on the agenda at the COP27 environment summit in Egypt is how to fund damage from the effects of man made climate change. Often the effects of climate change are felt the strongest in countries least responsible for creating the emissions. This year we’ve seen a range of extreme weather events including drought and flooding which scientists have attributed to man-made climate change. The idea of providing funding for such human-induced disasters has long been discussed informally at COP summits. Finally the issue is formally on the table. It's fraught with diplomatic difficulties, not least over who should pay and how much. We discuss some of the issues in getting a solution on this initiative known as ‘Loss and Damage’ with contributions from Josh Gabbatiss from the website Carbon Brief, Rachel Kyte, the Dean of Tufts University, Linnéa Norlander Assistant Professor of human rights and sustainability at the University of Copenhagen and Hyacinthe Niyitegeka, coordinator of the Loss and Damage Coalition.

Shaun The Sheep Jumps Over The Moon, Bronze Age Kissing and PPE Rubbish

ESA announce that Shaun The Sheep will fly around the moon this month aboard Artemis-1 mission. Philippe Deloo tells Gaia Vince what's in store for the woolly astronaut this month. Philippe is the team lead on the European Service Module, the part of NASA's Orion spacecraft which will be the workhorse of the new moon missions, ferrying four astronauts at a time to the moon and perhaps even beyond one day. This first Artemis mission, slated for launch 29th August, will check all the engineering bravado of the new launch and orbital systems ready for subsequent human passengers in a couple of years.Christiana Scheib, of the Universities of Cambridge and Tartu, is part of a team who seem to have pinpointed in time the moment the Herpes virus that causes cold sores first spread across human populations. By obtaining genomes of HSV1 from four individuals who died between the iron age and medieval times, their analysis suggests an initial emergence sometime in the Bronze age. The intriguing hypothesis that accompanies the discovery is that the variant's emergence was facilitated by a new trend among bronze age folk of romantic kissing. But as she describes, it's hard to be certain for "there is no gene for kissing".One way of restricting the spread of many viruses is of course various forms of PPE. The last few years have seen billions more items of PPE used on our planet, often without a clear plan for their disposal, and they get accidentally dropped and even deliberately dumped all over the world.

Deep Space and the Deep Sea - 40 years of the International Whaling Moratorium.

The James Webb Space Telescope is finally in business - what further treasures will it find? Also, the origins of the International Moratorium on Whaling, 40 years old this month.This week NASA invited President Joe Biden to help them publish the first of five images of full scientific value from the newest super telescope now operating a million miles away from us. It is capable of gazing as far deep into the sky as humans have ever gazed. That first image, an upgrade of one of the Hubble Telescope's "Deep Field" shots from some years ago, shows some of the oldest matter ever seen, including light distorted into smudges and whorls by the gravitational field of galaxies in line of sight from us, much nearer and younger than the light being bent around them.The other images show even more of what the telescope is capable of seeing. Dr. Stefanie Milam of Nasa's Goddard Space Flight Centre in Maryland, US and BBC Science correspondent Jonathan Amos talk to Gaia about this new, exciting phase in astronomy.This month marks 40 years since the International Whaling Commission decided to pursue a moratorium on commercial whaling. Many whales are still struggling, but scientists have seen several species recover since then. The moratorium followed campaigning in the 1970s by such groups as Greenpeace, and even the commercial success of audio recordings of humpback whales, released by Drs. Roger and Katy Payne. Greenpeace co-founder Rex Weyler describes to Gaia the motivations behind the original Save the Whale campaign, and some of his memories of intercepting a Russian whaling ship in 1975.Since 1982, cetacean science has come a long way, and scientists know far more about whale's behaviour, vulnerabilities and interaction with ocean climate and ecosystems than we did back then.

10 Years of the Higgs Boson

In 1964 a theoretical physicist called Peter Higgs suggested a mechanism via which elementary particles of a new theoretical scheme could obtain mass. It had been a thorny mathematical stinker in the framework that today we now call the standard model of particle physics. Ten years ago this July, the particle this mechanism predicted, the Higgs Boson, was confirmed to exist in experiments conducted at the Large Hadron Collider at CERN.Prof Frank Close, whose new book - Elusive - is published this week, is a friend of Peter's. The book describes the background to Higg's idea, and how a generation of physicists worked to test it and identify it. He and Prof Malcolm Fairbairn of King's College London discuss the significance at the time, what we we've learned since, and what we might in the future.As covid cases are on the rise again in the UK, Prof Jonathan Ball gives Marnie his observations on the current variants.

How hard is it to get to Mercury and why are we going? Also, do science festivals work? And why did mammals survive when dinosaurs died? Marnie Chesterton and guests dissect.As this programme went out, scientists and engineers eagerly wait for new images of the planet Mercury to arrive, snapped from a speeding probe passing just 200km from the surface, as it desperately tries to shed some velocity on its seven-year braking journey. ESA/JAXA's BepiColombo mission to Mercury is using gravitational swing-shots (just four more to go) to lose enough energy to eventually, in Dec 2025, enter orbit around the planet closest to our sun.Dr Suzie Imber of Leicester University has skin in the game, being co-investigator on one of the instruments that will eventually be able to teach us more than we've ever known about this bizarre world.Suzie is also last year's winner of the Royal Society's Rosalind Franklyn Award, and works hard doing science outreach talks and events to help inspire the next generation of scientists and engineers.Thurs 23rd June is International Women in Engineering Day, celebrating remarkable engineering as a career option. Report Emily Bird goes along to the Great Exhibition Road Festival to see how science festivals such as this one can help raise the profile of engineering and scientific endeavours in the society of tomorrow.One thing most kids like is Space. The other is dinosaurs. But what about long-dead Mammals? Prof Steve Brusatte of Edinburgh university is a palaeontologist and author whose last book on dinosaurs even led to him being consulted for the latest film in the Jurassic Park franchise. Why then does his new book focus on furrier beings in The Rise and Reign of The Mammals? He tells Marnie of the exciting millions of years of evolution that led to us, after the dinosaurs croaked their last,.Presented by Marnie Chesterton Reporting by Emily Bird Produced by Alex Mansfield

Inside Sentience

Marnie Chesterton and guests mull over the saga of an AI engineer who believes his chatbot is sentient. Also, climate scientists propose a major leap in earth system modelling, that might cost £250m a year but would bring our predictive power from 100 km to 1km. And the story of a Malaysian Breadfruit species that turns out to be two separate strains - something locals knew all along, but that science had missed.Philp Ball's latest book, The Book of Minds, explores the work still to be done on our conception of what thinking is, and what it might mean in non-human contexts. Beth Singler is a digital ethnographer - an anthropologist who studies societal reaction to technological advancement. They discuss the story this week that a google AI engineer has been suspended on paid leave from his work with an experimental algorithm called LaMDA. He rather startlingly announced his belief that it had attained sentience, publishing some excerpts from interactions he has experienced with it.Prof Dame Julia Slingo this week has published a proposal in Nature Climate Change, co-authored with several of the world's greatest climate scientists, for a multinational investment in the next generation of climate models. Currently, models of the global climate have a resolution of something like 100km, a scale which, they suggest, misses some very fundamental physics of the way rain, clouds and storms can form. Zooming into 1km resolution, and including the smaller physical systems will allow scientist to better predict extreme events, and crucially how water interacts in a real way with rising temperatures in different climes.And can zooming in on taxonomy reveal insights in conservation and biodiversity? Researchers in the US and Malaysia have described a species of breadfruit that has hitherto been considered one species by mainstream science. Locals have long described them as different species, and the genetics proves that view correct. Can more local, granular knowledge help us get a better handle on the conservation status of our planet's biodiversity?

Miscounting Carbon, EU Funding Stalemate, and How to Make a Royal Hologram

This week on inside science Marnie Chesterton is looking at how companies measure and account for their use of renewable energy, how politics is impacting science funding in the UK and the technology behind the Queen’s holographic stand in at jubilee celebrations. Dr Anders Bjorn from Concordia university in Montreal talks us through ‘Renewable Energy Certificates’ explaining how they can sometimes be disconnected from real-life reductions in emissions. As he explains in a paper in Nature Climate Change this week, this is a problem, with businesses buying renewable energy certificates that may, even with the best of intentions, mean that corporate estimates of how much they have transferred to renewable energy could be out by as much as two-thirds. For example, in Poland, where much of the grid is powered by fossil fuels, a company can buy RECs from energy producers in Norway, where so much of the grid is de-carbonised and users feel no need to purchase such a certificate. As negotiations on the New Greenhouse Gas Protocol get underway, and delegates in Bonn discuss COP 26 progress, yet more food for thought. In the UK, some long term collaborations and research structures are under threat as the ratification of UK membership of Horizon Europe continues to be delayed. This has led to some researchers running out of funds, some having to relinquish membership, and others moving to different institutions in Member Countries. Professor Nicky Clayton at the university of Cambridge has for many years run a “Corvid Palace” where she keeps very clever birds and examines their thinking. It is threatened with closure, and she is searching for funding to keep the research going, even setting up an open letter from academics around the world in support of this globally renowned facility.Carsten Welsh, a physicist at Liverpool University has also been impacted, facing a difficult decision about whether to give up leadership of his newly funded project or leave the country to pursue it. EU Horizon is one of the most ambitious and well-funded research and international collaboration schemes in science and with every EU nation signed up and countries like Canada and Japan keen to join too, it's no wonder the UK wants to take part. Martin Smith, head of policy lab at the Wellcome Trust explains what’s getting in our way and what might happen next for British scientists who rely on Horizon to fund their research. And finally, celebrations last weekend for the celebration of Her Majesty’s Platinum Jubilee were seemingly led by a holographic queen riding in the Golden State Coach at the head of the pageant in London. At least, that was how it was reported. But was it really? BBC Inside Science managed to track down the leader of the team that made it – whatever it was – happen, and in a generous world exclusive, Willie Williams, head of Treatment Studio, kindly spills the magic beans on quite how you make a Royal Hologram.

Monkeypox, Pompeii aDNA, and Elephant Mourning Videos

Why are non-African monkeypox cases causing concern? Also, the first complete human genome from a Pompeiian cadaver, and how YouTube is aiding animal behaviourists.As cases of monkeypox appear strangely dispersed around Europe and elsewhere in the world outside of Africa, BBC health and science correspondent James Gallagher outlines to Vic the symptoms and some of the mysterious elements of this outbreak.In Pompeii, scientists have for the first time managed to sequence the whole genome of an individual killed by the eruption of Vesuvius in 79AD. Serena Viva of the University of Salento describes the site of two individual's tragic demise all that time ago, one female aged around 50 years, and a younger male, both leaning on a couch in a dining room. Geneticist Gabriele Scorrano describes how the ancient DNA (aDNA) was preserved and extracted, and how the male individual's genome was so well preserved it could be sequenced in full. As they suggest this week in Nature, there weren’t too many surprises in what they found, but the ability to do this sort of science opens up a new era of Pompeiian archaeological treasure.Faced with covid lockdowns and unable to observe in the wild, elephant conservationists Nachiketha Sharma and Sanjeeta Sharma Pocharel decided to see if videos uploaded to YouTube could enlighten science on rare behaviours of Asian elephants. African Elephants are known to have a strange fascination, even respect, for the death of other elephant individuals, especially those near to their families such as calves and parents. Asian elephants’ thanatological (death related) behaviour is less well observed however. But the researchers turned to videos of strange grieving-like behaviour to begin a catalogue of the different reactions such as carrying dead calves, standing guard, or vocalizing. They dedicate their work, published by the Royal Society, to the elephants involved.This sort of research, using video observations captured and shared by members of the public are proving rather useful to zoologists and animal behaviourists. Ximena Nelson of the University of Canterbury in New Zealand was one of the first scientists to suggest the usefulness of trawling the internet for odd video of animals and explains a bit more to Vic.Presented by Victoria Gill Produced by Alex Mansfield

Buried Mars Landers, Freezing Species, and Low-Tide Archaeology

Since 2018, Nasa's InSight Mars lander has been sitting on the surface listening to the seismic rumbles of the red planet's deep interior. But this week, plans were announced to finally phase down its activity, as martian dust obscures too much of its solar panels to power it through the forthcoming winter. Jon Amos tells Vic Gill of some of its many successes, and quite why it didn't fly with a duster on board. 50 years of observations across Australia's northern tropical forests suggest yet more bad news for the climate. Trees’ mortality has, it seems, doubled since the 1980s. As Oxford University's David Bauman tells Vic, it seems to be linked to a drying of the air as temperatures rise, and if the trend is also true across the world's other moist tropical forests, they could rapidly slip from being carbon sinks, to carbon sources.Conservationists say we’re losing animal species faster today than at any point in the last 10 million years of Earth’s history. And one approach aims to save as many of those lost animals as possible – after they’ve died. Biobanking – saving frozen tissue from dead animals for future cloning or other reproductive technologies could buy us time to prevent extinction - or even reverse it. Vic visits Nature's Safe, where technology used in pedigree breeding is being deployed to preserve the cells and tissue of endangered species when individuals die or are euthanised, for possible research in the future, or even cloning.Meanwhile, 2.5 miles off the coast of Jersey, archaeologists are holing up in a medieval fortress waiting for the few lowest tides of the year to give them access to the Violet Bank - an area of reef thought once to have been home to Neanderthal populations, but which now is for most of the year submerged by the sea. Marnie Chesterton has been talking to UCL’s Matt Pope between the ebbs and flows. Presented by Victoria GillReporters: Marnie Chesterton and Jonathan AmosProduced by Alex Mansfield

Running Rings Around Matter

Astronomers have captured the first image of Sagittarius A*, the gargantuan black hole at the centre of our galaxy. Dr Ziri Younsi, University College London, shares what it took to capture a picture of a supermassive black hole that is 26,000 light-years away and from which (almost) nothing, not even light, can escape. The world’s largest and most powerful particle accelerator, the Large Hadron Collider, is restarting after three years of upgrades. Roland Pease visits the European Particle Physics Laboratory, CERN, to see how things are going, and looks back on some of the team's past successes. Also, how do you investigate the mysterious deaths of the world’s biggest fish when their bodies sink without trace? That’s the quandary facing marine scientists who’ve been trying to figure out what exactly is killing whale sharks. Freya Womersley, UK Marine Biological Association, shares how satellite tracking technology is helping us solve the mystery.And finally, what’s in a name? As our inventory of Earth’s biodiversity progresses, the number of species given a Latin name is also growing. So, where do scientists find their naming inspiration? In Royal Society Proceedings B this week, an analysis of nearly 3,000 parasitic worm species uncovered some intriguing patterns and worrying biases.

Precious Metals, Earlier Eggs, and Meaningful Meteorites

With the cost of living spiralling, many are probably thinking more about the price of food than lithium, titanium, copper or platinum. But the volatility in the global market for these materials - partly because of the pandemic and geopolitical unrest - is causing 'chaos' in the technology supply chain. Elizabeth Ratcliffe, Royal Society of Chemistry, tells Vic that many of us are unwittingly stockpiling these precious metals in our homes, in our old phones and defunct computers, because we don't know what to do with them. Reporter Samara Linton visits N2S, a company in Bury St Edmunds which has found a way to recycle the precious metals and other scarce elements in discarded circuit boards using bacteria. This week more evidence that spring is springing earlier, as Vic heads to what might be the most studied woodland in the world: Wytham Woods in Oxfordshire. Ella Cole, Oxford University, explains how climate change is causing birds to lay eggs three weeks earlier than they did in the 1940s. And Chris Perrins, of Oxford University, shares his thoughts on the changing woodland.And from new life to the very stuff of life. Could the building blocks of DNA have first been delivered to earth on a meteorite? In a paper in Nature Communications, scientists announce the discovery of the last two of the five key nucleobases locked in meteorites dating to the formation of the solar system. Samples of the Murchison Meteorite, a specific type of soft, loamy rock (CM2 carbonaceous chondrite) that fell to earth in 1969, have been re-examined, and the confirmation extends the ongoing debate around the nature and composition of terrestrial life's original crucible. Sara Russell, Professor of Planetary Sciences at London's Natural History Museum, helps Vic unravel the complicated and surprisingly controversial history of space rocks and primordial soup.Presented by Vic GillProducer: Alex Mansfield Reporter: Samara Linton

The Ebb and Flow of the Tidal Power Revolution

This week, we begin with a disturbing medical mystery. Since the start of the year, almost 200 children worldwide have fallen ill with hepatitis—or liver inflammation—without any apparent cause. Most of the children are under five, and nearly half of the cases were in the UK. Vic Gill asks clinical epidemiologist Deepti Gurdasani, Queen Mary University of London, what we do and don't know about these rare cases.Also on the programme, with a huge tidal range, Wales and the west coast of England have become the focal point for a new generation of tidal power plans. So, is the tidal energy revolution finally happening? Roger Falconer, Emeritus Professor of Water and Environmental Engineering at Cardiff University, and Andrew Scott, CEO of Orbital Marine Power, which has demonstrated a working tidal stream turbine - called O2 - off Orkney, share their insights.And fancy eating an insect burger? Or how about adding seaweed smoothies or mycoprotein meatballs to your diet? Fellow BBC science correspondent Helen Briggs shares how lab-grown proteins could make our diets much kinder to the planet.And a recent study has found that a fifth of reptile species are at risk of extinction. Conservation scientist and study co-author Monika Bohm, Indianapolis Zoo in the US, tells us how, despite the gloomy findings, she remains hopeful.

Building Better Engagement

Victoria Gill and guests ask why does scientific communication matters in society and how it might be done better, with Sam Illingworth, Berry Billingsley and Ozmala Ismail.The climate crisis and Covid-19 have shown over the recent years the importance of reliable, relatable, transparent and trusted science communication. But just like science itself, it comes in different forms and takes different approaches. Always keen to keep you up to date, BBC Inside Science takes a moment to discuss good practice and how it might be done better. Dr Oz Ismail is a dementia researcher who also finds time to do stand-up, public engagement and a podcast called Why Aren’t You A Doctor Yet?Sam Illingworth is an Associate Professor at Edinburgh Napier University who investigates science and communication between disciplines. He is also a poet and writer, and has a podcast called The Poetry of Science.And Berry Billingsley is Professor in Science Education at Canterbury Christchurch University.

A Trip-Switch for Depression?

Could magic mushrooms be the key to a revolution in treating depression? Professor David Nutt, director of the Imperial Centre for Psychedelic Research, thinks so. He tells Vic Gill about recent research suggesting that psilocybin - the psychedelic compound found in magic mushrooms - triggers rewiring of the brain in people with treatment-resistant depression. Vic Gill speaks with trial participant Steve Shorney who was diagnosed with depression 30 years ago. Nanobodies. That's the name scientists have given to the tiny antibodies found in the blood of camelids like llamas, alpacas and camels. Reporter Samara Linton heads to Berkshire to meet the llamas whose nanobodies were recently found to neutralise the Covid-19 virus. We hear from Professor Gary Stephens, University of Reading, who is responsible for the llamas' safety and well-being, and Professor James Naismith, director of the Rosalind Franklin Institute which is carrying out the pioneering research with engineered nanobodies. And just as the James Webb Space Telescope is poised to peer deep into the universe, we look at a recent image captured by its great predecessor, Hubble, which has thrown down a telescopic gauntlet.

Declining Data, Climate Deadlines and the Day the Dinosaurs Died

Covid-19 infections in the UK are at an all-time high. But most people in England can no longer access free Covid-19 tests, and the REACT-1 study, which has been testing more than 100,000 individuals since the pandemic began, ended last week after its funding stopped. Martin Mckee, Prof of European Health at the London School of Hygiene and Tropical Medicine, shares his insights on what these changes might mean for ambitions to 'live with the virus'. This week, the UN's latest Intergovernmental Panel on Climate Change (IPCC) report has unveiled a to-do list of ways to save the planet from climate catastrophe. How do scientists reach a global consensus on climate change amid war, an energy crisis, and a pandemic? Vic Gill speaks to report co-author Jo House, University of Bristol, and Ukrainian climate scientist Svitlana Krakovska who took part in signing off every line of the report while sheltering from the war in Kyiv. And from our planet's present and future to its ancient past. Scientists working on the Tanis fossil site in North Dakota in the US have dug up a dinosaur's leg, complete with skin and scales. Is this 66-million-year-old fossil, alongside similar nearby victims, the key to unveiling those transformative minutes after the infamous Chicxulub asteroid struck the earth and ended the era of the dinosaurs? BBC science correspondent Jonathan Amos has seen the fossil and speaks with Paul Barrett of London's Natural History Museum about the significance of this un-reviewed new finds. And from earth to Mars. After a year of analysing audio recordings from NASA's Perseverance rover, scientists have found not one but two speeds of sound on Mars. Trevor Cox, Professor of Acoustic Engineering at the University of Salford, guides us through this sonic wonder, and how sound may become a key tool for exploring distant worlds.

How can the UK get to zero carbon?

Energy is essential: every living thing needs energy to survive, and today’s industrialised societies consume enormous quantities of it. At the moment, the vast majority of this comes from burning fossil fuels that emit carbon. But the government is committed to reaching net zero carbon emissions by 2050. Meanwhile, oil and gas prices are rocketing, exacerbated by the ongoing war in Ukraine. And the energy price cap is being raised on April 1st, hitting millions of householders in the UK. While we await the government’s energy strategy, Inside Science looks at how to solve the problem, finding the best possible ways to meet our energy needs while slashing our carbon emissions. Joining us to discuss this are Alice Bell, co-director of the climate charity Possible, and Jan Rosenow, director at the Regulatory Assistance Project. We also hear from Chris Stark of the Climate Change Commission on how the government might meet its decarbonisation targets, visit a Cornish field that might be a rich source of homegrown lithium for batteries, and talk to Jonathan Atkinson from People Powered Retrofit about how to make our homes greener and warmer.

Racial inequality in UK science

This month the Royal Society of Chemistry released a shocking report on racial inequality at all stages of academia, from research funding to career progression. Black scientists in particular are unfairly disadvantaged when it comes to funding allocation. This is bad for them, bad for science, and bad for society. So how do we change things? Dr Diego Baptista from the Wellcome Trust, Professor Melanie Welham from the UKRI, and Dr Addy Adelaine, from the non-profit organisation Ladders4Action, join us to discuss the issue. Both of Earth’s poles were hit by heatwaves this week. The Arctic was 30 degrees above average for this time of year, and the Antarctic was an unprecedented 40 degrees above average. We are seeing more extreme temperatures everywhere on earth, but for both poles to experience such heatwaves at the same time is highly unusual. Ed Blockley of the Met Office’s Polar Climate Group explains what’s going on. One of the simplest ways to improve your local environment is to plant a hedge, which not only helps wildlife but can reduce flooding and pollution. But what kind of hedge should you plant? Scientists at the University of Reading and the Royal Horticultural Society are beginning a two year experiment to see which combinations of hedges bring the most benefits. Dr Tijana Blanusa tells us why planting hedges and generally greening our gardens is so important in the current climate.Presented by Gaia Vince Producer Cathy Edwards Assistant Producer Emily Bird

Global food security during Ukraine conflict

The Russian conflict in Ukraine is already causing hunger there, and as Ukraine and Russia are huge grain exporters, the crisis will be far reaching. Food prices everywhere are expected to rise, and there’s fear that the war could affect food supplies in some of the poorest parts of the world. Tim Lang, Emeritus Professor of Food Policy at City University of London, and Dr Hannah Ritchie, Head of Research at the website Our World in Data, join us to discuss food security. Lead is highly toxic to humans and other animals. One source of lead in the environment is the bullets and shot used to hunt wild game, and new research shows that lead shot has a significant effect on birds of prey such as eagles, buzzards and vultures across the whole of Europe. One of the study’s authors, Professor Debbie Pain, explains the research. Many of us have spent the past two years anxiously following Covid graphs, but from next month the government is cutting funding to several surveillance programmes. Mass free testing will also end, though the Office for National Statistics survey will continue. Given that case numbers are rising, is reduced monitoring wise? Professor Adam Kucharski from the London School of Hygiene and Tropical Medicine discusses how important surveillance has been in the pandemic. The last crewed mission to the Moon was half a century ago, and no one has made that one small step since. But a new NASA programme aims to change that, and tonight is the rollout of Artemis I, the first stage on a journey to return humans to the moon, including the first woman on the moon and the first person of colour on the moon. BBC science correspondent Jon Amos paints a picture of what we’ll see tonight.

High Seas treaty talks and discoveries from the deep

The High Seas make up most of our oceans but belong to no-one and are largely unregulated, leaving them at risk of plunder. UN talks start afresh this week with the aim of protecting the marine biodiversity of these vast swathes of living ocean. Covid-19 can shrink our brains and lead to cognitive decline, even in mild cases, according to a new study out this week. Professor Gwenaëlle Douaud, who led the research, explains how they used hundreds of brain scans to discover the effects of Covid infection. A completely different discovery this week was made at the bottom of the sea; we hear how, after 107 years, scientists have finally found The Endurance, the lost shipwreck of Antarctic explorer Sir Ernest Shackleton. How might the Russian invasion of Ukraine affect international space exploration? After a Twitter spat between a former NASA astronaut and the Russian space chief, we’re joined by BBC science correspondent Jonathan Amos and BBC Russian’s Nikolay Voronin to discuss how science in Russia and the rest of the world may be impacted by the current conflict. And finally, the stunning discovery of a 330 million-year-old vampyropod fossil, the earliest known relative of modern-day octopuses and vampire squids, gives us an opportunity to imagine the world it inhabited, a third of a billion years ago.

Cyber frontlines in Ukraine

As conflict continues in Ukraine, there are invisible ‘cyber frontlines’ running in parallel to the physical fighting. We hear how the country’s tech scene is responding to the Russian invasion, as Mike Sapiton, Tech Editor at Forbes Ukraine gives us a view from the ground, and Professor Madeline Carr explains why cyber warfare can be particularly dangerous. A major report published this week speaks to a different kind of crisis: climate change. There are stark warnings for humanity and the planet, with the Intergovernmental Panel on Climate Change assessing the impacts of global heating on people and places, as well as how we can adapt to a drastically changed world. One of its lead authors, Professor Richard Betts, reflects on the report. Russia is one of the world's biggest producers of coal, gas and oil, so what might their invasion of Ukraine, and the ensuing sanctions, mean for global energy supplies? Simon Evans, deputy editor of the climate website Carbon Brief, discusses whether we're more likely to see a push towards renewables and energy efficiency, or further reliance on fossil fuels.

World’s largest Jurassic pterosaur found on Skye

In a week of exciting fossils finds we get up close to a 170 million year old pterosaur, found on the Isle of Skye. And over in the States, some fossilised fish hold the clue to what time of year the dinosaurs, along with three quarters of life on Earth, met their end. We hear from researcher Melanie During who tells us how growth patterns in sturgeons' bones reveal the season of this mass extinction.Predictions for how our climate will change over the coming years are essential in setting and meeting emissions targets, however human behaviour is usually left out of climate model equations. Fran Moore and Katherine Lacasse explain why and how they factor public opinion, habits and political trends into their climate model. And finally, why is it so important we clean up after our pets?

Fusion energy smashes world record

This week the UK-based JET Laboratory broke its 25-year-old record for energy extracted by nuclear fusion - the process that powers the stars. Using temperatures 10 times hotter than the sun, nuclear fusion has the potential to provide vast amounts of energy at a very low carbon cost. But re-creating the power of the stars here on earth is no easy feat, and Roland Pease has been in Culham, speaking to the scientists at the forefront of this breakthrough.We discuss the Advanced Research and Invention Agency ( ARIA. The ARIA bill is about to go through the final stages of parliamentary approval and will have a budget of £800 million to play with over four years. But it’s not without its critics. Many in the science community have questioned ARIA’s transparency and accountability to the public, because the government have decided to exempt ARIA from Freedom of Information Requests. We hear from UKRI head Professor Dame Ottoline Leyser and Professor of Research Policy James Wilsdon. And from blue skies research to blue seas research, scientists have found a surprising seabed community that lives in the cold nutrient-sparse waters under the central arctic ocean: giant sponges. And it turns out these resourceful organisms have been feasting on the thousand-year-old remains of now-extinct worms. We hear from Teresa Maria Morganti from the Max Planck Institute for Marine Microbiology and Autun Perser from the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research.

The Continuing Story of the Nuclear Waste Bill

Whilst energy prices are shooting up due to gas demand, in the UK the plans for the next generation nuclear reactors are moving ahead. The costs of eventually decommissioning these, and the spent fuel products they will create is all part of the new contract. But what is to be done, and how far have we got with the 70 years of legacy waste piling up in the UK? Claire Corkhill of Sheffield university helps advise the government about nuclear waste disposal. As she tells Marnie, it's a long-term problem that must be dealt with some day, and even future nuclear fusion plants will have radioactive parts when they need replacing.You may feel that spring seems to come earlier each year. Ulf Buntgen and colleagues at the University of Cambridge have been using data from "Nature's Catalogue", a database of observations going back as far as the c18 to determine the dates each year that certain species of UK native plants first flower. And they have found a clear signal that plants are indeed flowering earlier due to climate change, some as much as a month earlier, on average, since the pre-1986 average. Aaron Rice of Cornell University speaks fish. But not fluently. His field of marine bioacoustics is growing fast. The oceans are, it seems, babbling with fish and other animal chatter. But does everything down there make a noise? In a paper published recently his team have traced evolutionary patterns in the ray-finned fish (which means nearly all the things most people would think of as a fish) and found that the ability to produce fishy sounds, be it bone vibrations, swim bladder vibrations or various other techniques, has likely emerged 33 times in this clade alone. Such convergent evolutionary history clearly suggests a strong selective pressure to do so. Aaron describes how much work there is to be done listening to fish, and how it can be used to help find out how life works, and how it may help us preserve it.

Predicting Long Covid, and the Global Toll of Antimicrobial Resistance

Prof Onur Boyman, Director of department of Immunology at University Hospital, Zurich, this week published a paper in the journal Nature Communications that presents a way of quantifying the risk of a Covid patient going on to develop Long Covid (or PACS as some call it) based on certain symptoms, but crucially also two key biomarkers in the blood. As he explains to Gaia, combining the levels in the blood of two key immunoglobulins (IgM and IgG3) with other pointers, first identified last year, allowed him and his team to make successful predictions as to the relative likelihood his sample group of patients might go on to still be exhibiting symptoms beyond four weeks after infection. Asthma is of particular interest to these researchers, partly because it can share this blood signal of Ig markers. Might it even also shed any light on things such as Chronic Fatigue Syndrome?Dr Claire Steves, of Kings College London, whose previous work on symptom gathering Onur's team have built upon, agrees this is a promising bit of work, and also discusses some other potential clues to the Long Covid mystery.But Covid of course is not the the only major cause of death in the world today. A major paper in the Lancet recently is one of the first deep estimates of the global health burden of Antibiotic Microbial Resistance. And it suggests that 1.25 million people died in the world in 2019 because many bacteria are evolving a resistance to our favourite antibiotics. As Prof Chris Murray, Director of the Institute for Health Metrics and Evaluation at the University of Washington who led the massive collaboration explains. The surprisingly huge number points to a massive and growing problem that political and health leaders around the world must address.And finally, the genetics of fingerprints might be a bit better understood thanks to work published in Cell recently. Dr Denis Headon of the Roslyn Institute at the University of Edinburgh talks to Gaia about a huge survey he and colleagues have done looking at the hints certain genes can give as to the types of fingerprints you grow. The genes that seem to govern the general form of your prints are the ones that shape your limb development, rather than skin patterns as perhaps might be expected. And a pro-tip if you want to search the literature for more info on this: use the word "dermatoglyph" rather than the overused and progressively meaningless word "fingerprint".Presented by Gaia Vince Producer Alex Mansfield Assistant Producer Emily BirdMade in Association with The Open University.

The 'perfect' depth for a destructive eruption

Why was the blast from the Hunga-Tonga-Hunga-Ha'apai volcano so explosive? Where are we on the global climatic thermostat? And how you can get involved in the Big Repair Project.Gaia Vince speaks with Auckland University volcanologist Prof Shane Cronin, one of the few human beings to have visited the now-disappeared volcanic land bridge that stretched until last week between the islands of Hunga-Tonga and Hunga-Ha'apai. It was destroyed in the disastrous eruption of the volcano beneath it last week that has wrought such devastation to the nation of Tonga, and whose effects were felt in the Americas and detectable all around the world. Why was this submarine eruption quite so explosive, given that the eruption itself was not one of the biggest or longest in living memory?Previous eruptions - notably Mount Pinatubo in the Philippines in 1991 - released huge amounts of particles and sulphates into the stratosphere such that they had a cooling effect on the atmosphere globally, lasting 2-3 years. Prof Richard Betts, Head of Climate Impacts at the UKs Met Office tells Gaia how current estimates of the recent eruption's emissions suggest it will not have such an affect, their being around ten times less than the 1991 event.Richard was one of the contributors to the UK Government’s Climate Risk Assessment 2022 which was published this week. He describes to Gaia some of the modelling that went into it, and the urgency of cutting CO2 and similar emissions it describes.Last year Prof Mark Miodownik, head of the Institute of Making at UCL made a series for Radio 4 called Dare to Repair, looking at the vanishing art and practice of repairing our old and malfunctioning consumer devices, rather than binning them and buying new ones as most of us do these days.At the end of 2021 Mark, together with representatives from manufacturers, consumers, and other groups, took part in a round-table meeting to discuss possible challenges and measures to increase the so-called Right to Repair, towards building a circular economy in the UK for recycling plastic and metals. In this week's show he launches a new citizen science project aimed at gathering granular data on UK citizens views and practices when it comes to "disposable" electronic devices.

The Rutland ‘Sea Dragon’, An Astronomer's Christmas and some Animal Magic

After 20 years of planning, preparation and a nail-biting build up fraught by delays The James Webb Space telescope finally launched on Christmas day 2021. Anxious astronomers across the globe looked on as the JWST then completed even riskier manoeuvres to unfurl the 18 hexagonal components that make up its 6.5 meter diameter primary mirror. Cosmologist Dr Sheona Urquhart from the Open University tells us about the astronomical community’s tense Christmas day. Fresh from a TV spot on BBC Two’s Digging for Britain this week, Dr Dean Lomax and PhD candidate Emily Swaby share their excitement unearthing Rutland’s ‘Sea Dragon’ and explore what this find could tell us about Ichthyosaurs. At over 10 meters long this ancient ocean predator is the largest complete fossil of its kind to be discovered in the UK. Ichthyosaurs are commonly associated with Dorset and Yorkshire coastlines where fossils are often revealed as surrounding rock is eroded by the elements. Finding an ichthyosaur fossil inland is unusual but not unexpected as the higher sea levels 200 million years ago would put the east midlands underwater. And whilst the palaeontologists have been struggling through the Jurassic mud, cognition researchers at the University of Cambridge have been wowing their birds with magic tricks. Professor Nicky Clayton FRS, Professor of Comparative Cognition, explains what we can learn about the way jays think by assessing their reaction to different sleight-of-hand tricks. Corvids, the family to which these feathered friends belong, have long interested researchers due to their impressive cognitive abilities and Nicky’s team has shown that their Jays are not fooled by all of the same mis-directions as we are, but are fooled by some. And it could be down to not being able to tell the difference between a finger and a feather.Presented by Marnie Chesterton Produced by Alex Mansfield Assistant Producer Emily BirdMade in association with The Open University

Deep ocean exploration

UCL oceanographer Helen Czerski explores life in the ocean depths with a panel of deep sea biologists. They take us to deep ocean coral gardens on sea mounts, to extraordinary hydrothermal vent ecosystems teeming with weird lifeforms fed by chemosynthetic microbes, to the remarkable biodiversity in the muds of the vast abyssal plains.Helen's guests are Adrian Glover of the Natural History Museum in London, Kerry Howell of Plymouth University and Alex Rogers, scientific director of REV Ocean. They discuss the dramatic revelations made by deep ocean explorers in just the last forty years, and the profound connections that the deep sea floor has with life at the Earth's surface. They also consider the threats to the ecosystems down there from seabed mining and climate change.Producer: Andrew Luck-BakerBBC Inside Science is made in association with the Open University.

A new space age?

Dr Kevin Fong convenes a panel of astronautical minds to discuss the next decade or two of space exploration.2021 was an eventful year in space. Captain James Kirk a.k.a William Shatner popped into space for real for a couple of minutes, transported by space company Blue Origin's tourist rocket New Shepard. Elon Musk's Space X ferried more astronauts and supplies between Earth and the International Space Station, using its revolutionary resuable launchers and Dragon spacecraft. On Mars, the latest NASA robot rover landed and released an autonomous helicopter - the first aircraft to fly on another planet. 2022 promises even more. Most significantly NASA plans to launch the first mission of its Artemis programme. This will be an uncrewed flight of its new deep space vehicle Orion to the Moon, propelled off the Earth by its new giant rocket, the Space Launch System. Artemis is the American space agency's project to return astronauts to the lunar surface and later establish moon bases. China has a similar ambition.Are we at the beginning of a new space age and if so, how have we got here? When will we see boots on the Moon again? Could we even see the first people on Mars by the end of this decade? Even in cautious NASA, some are optimistic about this.Kevin's three guests are:Dr Mike Barratt, one of NASA's most senior astronauts and a medical doctor, based at the Johnson Space Center in Houston, Texas Dr Anita Sengupta, Research Associate Professor in Astronautical Engineering at the University of Southern California Oliver Morton, Briefings editor at The Economist and the author of 'Mapping Mars' and 'The Moon'Producer: Andrew Luck-BakerBBC Inside Science is made in association with the Open University

The Origin of Celtic Culture in Britain?

Victoria Gill hears of ancient DNA evidence for an unrecognised mass migration from continental Europe 3,000 years ago that may even have brought the Celtic languages with it.In a paper in the journal Nature, an international team of researchers have gathered hundreds of middle-late Bronze Age DNA samples to identify a moment in pre-history when half the ancestry of people living in southern Britain became continental European. Sometime around 1000 BC, continental Europeans living in Kent spread rapidly into what is now England and Wales. As Prof Ian Armit tells Vic, the spread need not have been one event, and likely spanned around 200 years, but by the start of the Iron Age, Britons' DNA was 50% changed. The researchers suggest further that this may have been the time when Celtic languages spread from the continent into the islands too. Data are starting to be published that suggest the Omicron variant of SARS CoV-2 may be a little less awful than was first feared, though it clearly is still a lethal foe. Prof Penny Moore, one of the scientists in South Africa who helped alert the world to the new virus is very tentatively relieved that death and hospitalisation numbers there and in the UK are beginning to show clinically some of the resilience that earlier strains and vaccines may have bestowed on populations. Three "Glimpses of Spike", either through prior infection and survival or vaccination and boosting seem to be accompanied by improved survival rates.Gaia Vince has been to the Arctic Circle to talk climate change and reindeer. Sami language and culture in Lapland is under strain as climate change rapidly changes alters the predatory threats reindeer farmers face, increasing numbers of wolves and even sea-eagles that prey on young reindeer calves. And over at UCSC in California, recordings of elephant seal pups have been played to maternal harems to ascertain how well mothers recognize their own. Caroline Casey and colleagues report in Royal Society journal Biology Letters, how they can spot their own offspring from their call alone in as little as two days after birth. But if they can do that, why then do so many lactating females feed pups that aren’t their own? Elephant seal mothers fast throughout lactation and lose a huge percentage of their own body weight, quite what the evolutionary driver is for this behaviour remains uncertain, but it can’t now be a case of mistaken identity.

The James Webb Space Telescope

The launch of the James Webb Space Telescope is only days away. Scheduled for lift off on 24 December, the largest and most complex space observatory ever built will be sent to an orbit beyond the moon. James Webb is so huge that it has had to be folded up to fit in the rocket. There will be a tense two weeks over Christmas and the New Year as the space giant unfurls and unfolds. Its design and construction has taken about 30 years under the leadership of NASA’s Goddard Space Flight Center.With its huge 6.5 metre-wide primary mirror, the giant observatory promises to extend our view across the cosmos to the first stars to shine in the early universe. That’s a vista of Cosmic Dawn: the first small clusters of stars to form and ignite out of what had been a universe of just dark clouds of primordial gas. If the James Webb succeeds in capturing the birth of starlight, we will be looking at celestial objects more than 13.5 billion light years away. Closer to home, the telescope will also revolutionise our understanding of planets orbiting stars beyond the solar system.BBC science correspondent Jonathan Amos reports from the European Space Agency’s launch site in French Guyana from where James Webb will be sent into space. He talks to astronomers who will be using the telescope and NASA engineers who’ve built the telescope and tested it in the years leading to launch.Producer: Andrew Luck-BakerBBC Inside Science is made in association with the Open University.Image: James Webb Space Telescope.

Initial Omicron Lab Data, Creative Naps, and Fishy Sounds.

T-Cells in vaccinated people may be holding the fort, or at least fighting serious illness, against the latest SARS CoV2 variant. Also, how the briefest of sleeps aids creativity.Prof Penny Moore, of South Africa’s National Centre for Infectious Disease and Witwatersrand University in Johannesburg, joins us again this week to give us an update from the front line of scientists trying to get the data we need to try to predict the seriousness of the omicron variant. These early data, published as pre-prints and not yet peer-reviewed, seem to suggest that for those in the world lucky enough to have "seen a spike" three times (double vaccination plus booster, or double vaccination plus recovered from infection) the chances of serious illness remain similar to earlier variants.One chink of hope continues to be the fascinating response of the "killer" T-Cells. Prof Danny Altmann of Imperial College London attempts to give us a T-Cell 101 course. This other division of the body’s defences, besides the binding antibodies of which we hear so much, may be more resilient to the sorts of mutations the virus has shown so far, and also perhaps have a slower waning in their ability to recognize it at all.What did Salvador Dali and Thomas Edison have in common? A fondness for the occasional creative nap. And this week scientists suggest they weren't wrong.Delphine Oudiette, a sleep researcher at the L’Institut du Cerveau et de la Moelle épinière in Paris, has been experimenting with the idea that just a small nap, where you doze off for a few seconds but don't fall into deep sleep statistically helps you solve creative or mathematical problems. Her results are published in the journal Science Advances. Meanwhile, in shallow seas off Indonesia, attempts to regrow coral reefs previously pounded to rubble by fishing with explosives, really sound like they are recovering. How do scientists know? By swimming about with microphones of course. Dr Tim Lamont, a marine Biologist at the University of Exeter has been listening to thousands of recordings of fish and other marine animal noises and talks Vic through some of the odder ones that so far can't be recognized. He says the sheer number and frequency of the odd sounds point to an ecosystem beginning to thrive. The coral rebuilding strategy there won't work for all the world's dwindling corals, but this new way of monitoring success or failure makes for a great listen.Presenter: Victoria Gill Producer: Alex Mansfield Assistant Producer: Emily BirdMade in Association with The Open University

When Pandemics Collide

As virologists around the world race to investigate the latest SARS CoV2 variant of concern, the UN’s World AIDS Day this week reminds us of the other global pandemic raging for some 40 years. Much of the work achieved over the last two years on SARS CoV2 has been achieved because of the investment made into, and the understanding gained from, HIV research over the last two decades. But to what further extent do they overlap in the population? There is a theory that the omicron variant, displaying so very many mutations compared to previous variants, might well have been incubated in a person suffering from a compromised immune system, possibly due to HIV, in whom the covid virus was able to linger longer than in fitter individuals. Prof. Penny Moore, of South Africa’s National Centre for Infectious Disease and Witwatersrand University in Johannesburg, is one of many virologists who transferred from HIV to coronavirus research, and hers, like hundreds of labs around the world, is racing to clone the parts of the omicron virus to enable research into its transmissibility and severity as soon as possible. She describes to Vic what we yet know and what we don’t about it, and also how it is high time to bring the same sense of urgency back to HIV research.Nottingham University’s Prof. Jonathan Ball is another virologist who suddenly transferred experience over to coronaviruses early on. He outlines something of what is really happening when viruses mutate, and how the arms race between host and invader can play out. Our regular Inside Science listener will be interested to know that this week Merlin Sheldrake was awarded the Royal Society’s Science Book Prize, sponsored by Insight Investment, and the hefty cheque that accompanies it, for his book Entangled Life: How Fungi Make Our Worlds, Change Our Minds and Shape Our Futures. Merlin is one of several high profile advisors to something called the Society for the Protection of Underground Networks - SPUN. They have received funding recently to begin an international mission to map the world’s subterranean fungal mycelial networks, including the infamous Wood Wide Web. SPUN Co-Founder Prof. Toby Kiers of VU University in Amsterdam tells Vic about the need to preserve, map and cherish this unseen yet essential part of the global ecosystem.And could rising sea levels paradoxically be used to help fight climate change? Researchers up in St Andrews took Vic for a squelch about the salt marshes reclaimed recently by the sea in an estuary near Grangemouth, where flora and fauna are thriving just a few years since the seas were allowed back in. Finally, you may have thought that wasps eat meat whereas bees eat honey and nectar. But this week we learned that some bees eat meat, preserving it in honeycombs to feed young and augment their own nutrition. Intrepid field entomologist Laura Figueroa of Cornell University describes to Vic her work in the jungle with Vulture Bees, social bees that over evolutionary time seem to have rescinded their vegetarian instincts and now are happy to enjoy a bit of “chicken on the side”. Laura found that they can digest their flesh because of big adjustments to their gut microbes, including acid-loving bacteria also found in other carnivorous animals.

Malaria: what's in it for the mosquito?

Malaria, a disease that infects hundreds of millions of people and kills hundreds of thousands each year. It is caused after a plasmodium parasite is passed from a blood-feeding mosquito into a human host. Subject to much research over hundreds of years, of both host and parasite, one of the evolutionary mysteries has been why the plasmodium so prospers in the mosquito populations in infected areas. Why haven’t mosquitoes’ immune systems learned to fight back for example? In short, what’s in it for the mozzies? Ann Carr, working with Laurence Zwiebel at Vanderbuilt University, reports in the journal Nature Scientific Reports how they managed to discover a mutual symbiotic relationship between the plasmodium and the mosquito. Using advanced sequencing technology they discovered that the infected insects can live longer, and have enhanced sensing (olfaction) and egg positioning than their uninfected brethren. This, in turn, could help them finds meals better, bestowing higher numbers of infection opportunities for the parasite, and benefitting both.NASA this week successfully launched its DART mission, which will next year attempt to nudge an asteroid in its orbit by smashing a mass into it. Could this method allow future humans, endangered by an impending collision push an asteroid out of the way to save the planet? It is billed as human’s first ever “earth-defence mission”, but as relieved-sounding mission leads Nancy Chabot and Andy Rivkin of Johns Hopkins University told the BBC, it is perhaps finally time to stop talking about these sorts of things and have a go.Less relieved perhaps are astronomers around the world, as the James Webb Space Telescope team announce a further small delay to its launch to sometime after December 22nd. The BBC’s John Amos a few weeks ago stood in the presence of the telescope before it was coupled to the launch vehicle, and spoke with ESA’s Peter Jensen about its cost and complexity. BBC Inside Science is planning a special episode devoted to the instrument to accompany the launch of this successor to the Hubble Space Telescope. Watch, as they say, this space...And finally an insight perhaps into the origin of words and language. Apart from onomatopoeia, where a word can sound like the noise of a noise-making thing, can a word sound like other properties, such as for example its shape? In the late 1920s psychologists found that different people would match certain made-up words with the same abstract shapes. This “Bouba/ Kiki” effect has been studied since, where the word “Bouba” is associated with rounded blobby shapes, and “Kiki” with spikier, angular forms.But there wasn’t so much evidence whether or not the effect worked across different languages or different written alphabets, until now.Aleksandra Ćwiek of Leibniz-Zentrum Allgemeine Sprachwissenschaft in Berlin tells Gaia of her international study (published in Royal Society Phil. Trans. B) looking at the effect in 25 different languages and cultures. The effect is robust across the different writing systems and locations, so the link is not simply about the shape of a letter b or letter k when written in a latinate alphabet, but could allude to something much deeper.Presented by Gaia Vince Produced by Alex Mansfield Assistant Producer, Emily BirdMade in Association with The Open University.

Yet More Space Junk; COP-up or COP-out; The End of Bias.

Earlier in the week the current ISS crew had to prepare to evacuate after Russia tested an anti-satellite weapon, spreading thousands of high velocity shards of ex-satellite into a reasonably low-earth orbit and potentially endangering many other earth observation and communication satellites of all nations. How can we clear this and all the other debris? BBC Space Correspondent Jonathan Amos tells Gaia Vince about the Russian test and of efforts to de-orbit some other deceased orbital vehicles.Simon Evans, deputy editor of the website Carbon Brief, was one of many attending the COP26 summit which ended at the weekend. How do all the declarations, promises and the "Glasgow Pact" itself add up in the great carbon ledger we all need to worry about?

Propane: Keeping Your Cool as the World Warms Around You

How propane might prevent air conditioning and refrigeration becoming an even bigger burden as our planet warms. Also, covid antiviral pills, and how we forgot to breathe properly.The Montreal Protocol is famous for reducing CFC emissions to help protect the Ozone Layer. We only started using things like CFCs as refrigerants in our fridges and air-conditioning because they weren't as flammable as many alternatives. They were mainly replaced by HFCs, though these are also on the way out. The reason? Their huge greenhouse warming potential (or GWP). Propane has long been thought to be an alternative because of its comparatively tiny GPW, but the safety standards haven't been in place in much of the world for many of the types of application that would make the big difference. Sophie Geoghegan, Climate Campaigner at the Environmental Investigation Agency, and Asbjørn Vonsild who has been working on some of the new standards, due to become normal in Europe next year tell Gaia what greenhouse savings there are to be made, both in terms of efficiency and the contents of the systems themselves. If public opinion and consumer choice can drive the transition as our cities heat up.This week two new Anti-viral pills that are designed to fight SARS CoV2 infections have made headlines in the UK. Professor Penny Ward is Chair of the Faculty of Pharmaceutical Medicine’s Policy Expert Group, and explains how they work, how they were developed, and when they will be properly available. And in the penultimate of our 2021 Royal Society Insight Investment Science Book Prize shortlisted authors, science journalist James Nestor describes his book, Breath: The new science of a lost art.

How Whales Farmed For Food, COP progress, and The Last Stargazers

Gaia Vince hears how blue whales' huge appetites and energetic eating behaviours helped generate more food for themselves. Also, an update from COP26, and Emily Levesque on The Last Stargazers.New research published this week in the journal Nature reveals new insights into blue whales eating habits. Matthew Savoca and colleagues suggest these biggest of marine animals actually eat up to three times the mass of krill previously estimated. And they do this by finding the blooms of krill and using a spectacular lunging approach to open their massive mouths and filter the gulp of seawater for tonnes of food. But how come, since the near destruction of their population by commercial whaling in the twentieth century, are current krill populations lower than when the voracious whales themselves were far more numerous? Shouldn't there be more krill now than then?The answer, as Victor Smetacek, of the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research in Bremerhaven, describes to Gaia is that whales themselves help to keep iron in the upper waters of the southern oceans, re-fertilizing it for the lower ecosystem member like phytoplankton, and their powerful diving lunges and defecation effectively plough the waters, akin to herds of bison treading manure into prehistoric grass plains.Former GSO David King, of the Centre For Climate Repair at Cambridge University, is beginning experiments next year that seek to mimic this whale-defecation effect to bring about eventual repopulation of whales and fish to allow the oceans to restart this historical cycle.From Glasgow, above the hubbub of delegates and dignitaries CarbonBrief's deputy editor Simon Evans talks to Gaia about his perceptions of progress so far at the COP26 climate summit. Amongst the flurry of declarations so far this week, what are the details and how do they add up towards our eventual recovery back down to the 1.5C rise everybody is talking about?And in the latest of Inside Science's interviews with shortlisted finalists of this year's Royal Society Insight Investment Science Book Prize, Prof Emily Levesque, an astronomer at Washington State University tells Marnie Chesterton of her adventures and astronomical anecdotes at some of the world's most famous observatories. Researching her book, "The Last Stargazers: The Enduring Story of Astronomy’s Vanishing Explorers", she interviewed hundreds of practicing and practical astronomers, many of whose jobs, she suggests, will soon be transformed as the act of observation becomes more remote, automated, and data-heavy.

Atmospheric Pollutants and Where to Find Them

This week London's Ultra Low Emission Zone was extended to 18 times its previous size. In an effort to cut levels of various nitrogen oxides and other gases dangerous to humans from urban air, cities encouraging lower emission vehicles is a trend soon stretching across the UK and other European countries. But some are sceptical as to their efficacy. Dr Gary Fuller of Imperial College London is author of The Invisible Killer, and has been studying the air in London and elsewhere since these zones began.As COP26 begins in Glasgow, a wealth of climate science is being published and publicised. Victoria Gill describes a couple of stories this week that point out quite how complex the science is, let alone the diplomacy and economics. Whilst the world's forests taken as a whole undoubtedly still capture more CO2 than they release, research this week shows that ten of Unesco's World Heritage Forests - making up for an area twice the size of Germany - have in the last ten years actually moved from being a carbon sink to a carbon source. There are several reasons, land use pressure being one of them, but also extreme climate events like wildfires (and even a hurricane in one instance) have tipped the balance, and show what how sharp the knife edge is for natural resilience. Meanwhile, the Financial Times reports that scientists have found an unexpected outflow of methane into the atmosphere from a site very close to the COP26 conference centre in Glasgow, highlighting just how great a challenge net zero will be.Alongside some of humans' most earth-changing achievements, the domestication of the horse stands as something outstanding in human history. Without it, war, traded and culture would be unrecognizable. But quite when and where the modern horse originated has been something of a mystery. In Nature this week, researchers have published an extensive study into ancient DNA that seems to pinpoint finally a moment and a place where this happened, 4,200 years ago.

The Possible Impact of false-negative PCR Tests

As many as 43,000 PCR tests for people living in and around the South West of England could have been wrongly returned as negative recently, thanks to a seemingly unknown error, or errors, at a laboratory near Wolverhampton. For an extraordinarily long time the mistakes went undetected, and every day many hundreds of people who really had Covid, were told they hadn't.To discuss the numbers and difficulty in calculating the full tragic consequences of the events, Marnie Chesterton speaks to Dr Deepti Gordasani of Queen Mary, University of London, and Dr Kit Yates, of Bath University.How many people may have died as a result of this? BBC Inside Science's back-of-the-envelope suggests 500-1000 preventable deaths, and counting..As accusations of fossil fuel lobbying begin to encircle the pre-negotiations of the COP26 negotiations, we heard last week of the sad death of Dutch climate scientist Geert Jan van Oldenborgh. Listeners to BBC Science programmes will recognise his work from earlier this year, as flash floods and heatwaves ravished Europe and North America, when he and his colleagues at the World Weather Attribution Initiative were able to say unambiguously that these events could only have happened because of anthropogenic climate change. Roland Pease looks at Geert Jan's work and legacy.And the latest of the Royal Society Book Prize finalists to speak to BBC Inside Science is Stuart Ritchie, a psychologist at Kings College London. His book explores the murkier corners of science as a process. Certainly the so-called replication crisis has dogged psychological sciences for several years, but in "Science Fictions: How Fraud, Bias, Negligence, and Hype Undermine the Search for Truth" Stuart outlines quite how deep some of the flaws in the modern experimental reporting and publishing model go, and in almost all fields. However, as he explains to Marnie, there may be ways of rescuing the great achievement of the scientific method by tweaking some of our peer-review norms.Presented by Marnie Chesterton Produced by Alex Mansfield Made in association with The Open University

Dr George Stothart, has led the team in the development of this simple 2 minute test.Prof Thomas Scott of Bristol University and team develop robotic techniques to scan areas of high radiation that would otherwise be unsafe for humans to enter. Their rolling, quadruped or even flying robots have recently been deployed in and around the reactor building at the Chernobyl disaster site. Authorities there have recently been licensed to begin disassembling remains inside the vast concrete shield, but as they do so, areas of intense radiation are likely to shift from day to day.

Surprising choice for Nobel prizes in a pandemic?

This week saw the announcement of the Nobel prizes for physiology or medicine, chemistry and physics. None of them reward research connected with Covid. Roland Pease, science journalist and Nobel watcher, and Gaia Vince discuss the decisions, which some have said are controversial in this pandemic year. The BepiColombo space craft, a joint European and Japanese mission, has just completed its first fly-by of Mercury, after a three year journey. Professor Dave Rothery, a planetary geologist at the Open University, who’s been involved since the early days of the mission in the 1990s, talks about what Mercury's cameras have seen and what the mission aims to find out when it finally gets into orbit around the planet in 2026.Plants remove carbon from the air during photosynthesis, and forests will be a key part of meeting our climate goals. But there’s a lot of uncertainty about how forests will react as temperatures and CO2 rise. Now researchers at University of Birmingham have bathed ancient oak trees in the sort of carbon dioxide concentrations we expect in 2050, and measured the impact. Anna Gardner led the research from a forest in Staffordshire. The shortlist for the Royal Society Insight Investment Science Book Prize for 2021 was announced last week. Inside Science will be featuring the six authors. The first is The Sleeping Beauties: And Other Stories of Mystery Illness by Suzanne O’Sullivan. She's a consultant neurologist at the National Hospital for Neurology and Neurosurgery in London, who’s been described as “a detective of the mind”. Suzanne O’Sullivan specialises in epilepsy but this leads her to see a number of patients with symptoms such as unexplained paralysis or blindness. For The Sleeping Beauties, she travelled around the world investigating what is often referred to as psychosomatic illness. Sometimes whole groups of people have been affected in mysterious ways. Claudia Hammond spoke to her about the strange case of refugee children in Sweden who fell asleep for years at a time.

Covid vaccine boosters; why we don't have a tail; cassowary domestication; Royal Society Science book prize shortlist

Booster vaccines are now being offered to people in England most at risk of Covid, who had their second jab at least 6 months ago. Most people are getting an mRNA vaccine as a booster, mainly the Pfizer one. Dr Andrew Ustianowski, national clinical lead for the UK COVID Vaccine Research Programme, and infectious diseases consultant in Manchester, explains why people are not being offered new vaccines, specifically tweaked to prevent the current highly transmissible delta variant. And he talks about a trial with a new vaccine that works against more than just the spike protein. Why don’t we have a tail? We share that absence with our primate cousins, the great apes. What made the difference genetically speaking has eluded scientists, until now. Professor Jef Boeke of NYU Langone Health tells Gaia Vince why it was a change in just one gene that caused us to lose our tail.New research just published in PNAS pushes back the origins of farming by thousands of years. Professor Kristina Douglass of Penn State University and team studied 18 000 year old eggshells of cassowaries, found in human shelters in New Guinea. She explains how the finds suggest that these Pleistocene people had domesticated these large flight less birds. And six authors this week learned that their books have made the shortlist of the Royal Society Insight Investment Science Book Prize for 2021. Chair of the judges, Luke O’Neill, Professor of Biochemistry at Trinity College Dublin, tells Gaia how the panel made their choices from the 350 books entered.

La Palma volcano; wind energy in the UK; origins of SARS-Cov2; Formula 1 safety

Thousands of people have been forced to flee the path of the lava that has been spewing from the Cumbre Vieja volcano on La Palma since Sunday 18th September. Dr Rebecca Williams of Hull University is an expert on the geology of the Canary Islands and tells Gaia Vince that eruptions are regular events on the islands. There's been much discussion about where we are going to get our energy from in the UK. Gas prices are soaring, a fire has knocked out a key power cable, and the weather has affected the amount of power that can be generated from our wind turbines. And to meet our climate targets we're going to become ever more dependent on renewable, and variable, sources. Tom Butcher from the Met Office talks about wind forecasting. He says that the winds have been between 10% and 20% lower in intensity this summer. Professor Deborah Greaves, of Plymouth University and Head of the Supergen Offshore Renewable Energy Hub, explains how the UK is planning to increase the number of wind turbines, moving into deeper waters. A team from the Institut Pasteur in Paris, investigating bats in caves in Northern Laos, has found bats that are infected with a coronavirus that’s genetically almost identical to the one now causing Covid in humans. Lead researcher Dr Marc Eloit discusses what they have discovered and how coronaviruses could move from bats to humans. Lewis Hamilton and Max Verstappen had what looked like a very serious crash at their recent Formula 1 race in Italy. Max Verstappen’s car landed on top of Lewis Hamilton’s, but amazingly Hamilton got out unscathed. The safety features on these cars which can travel at more than 200 mph, are very sophisticated. Nick Wirth, a Fellow of the Royal Academy of Engineering who has many years experience of engineering in the F1 world, describes the Halo which saved Lewis Hamilton's life.

Perseverance drills on Mars; space tourism; Australian fire debris and algal blooms; DNA vaccines against Covid

NASA's Perseverance rover has been trundling around the Jezero crater since it landed successfully in February 2021. A few weeks ago it made its first attempt at collecting a sample of rock. Unfortunately the rock turned out to be so crumbly it disintegrated away. But Perseverance lives up to its name and has been drilling elsewhere and has now collected two samples. The rover has stored them in special canisters for later collection. Katie Stack-Morgan, Deputy Project Scientist of the Mars 2020 mission at NASA, tells Gaia Vince what they've found out so far.The Inspiration 4 mission has just blasted off from the Kennedy Space Center with 4 civilian astronauts on board. Unlike previous billionaire space flights, which have shot up far enough to officially cross into space before immediately returning, these four are going further out than the International Space Station, where they will orbit the earth for three days. BBC Science Correspondent Jonathan Amos talks about the recent boom in space tourism, and about the Chinese rover on Mars. The terrible Australian wildfires of the summer of 2019/20 had a devastating impact, burning across more than 18 million hectares and causing loss of life and livelihoods.. Now, it turns out the impacts stretched far beyond Australia. Climate scientists have been looking at satellite images of the vast Southern Ocean, which plays a major role in controlling the global climate, and found massive algal blooms, fertilised by debris blown thousands of kilometres from the fires. Gaia discusses the observations with Nicolas Cassar of Duke University, one of the authors on a recent Nature paper, and what they tell us about geoengineering to cool down the earth. This month India licensed the world’s first DNA vaccine against Covid. Jonathan Ball, Professor of Virology at the University of Nottingham, is involved with a DNA vaccine that is just starting in clinical trials. He explains the pros and cons of this kind of vaccine. It could be of benefit to those who are needle phobic.

Climate change and oil and gas exploration; cutting methane emissions; African wild dog populations; freezing eggs and sperm

We’re just weeks away from the big international climate talks in Glasgow, where governments will be trying to figure out a workable plan for how to keep global temperature rise below 1.5 degrees. Gaia Vince explores a couple of strategies to tackle climate change.By far the biggest source of the rise comes from the release of greenhouse gases when we burn fossil fuels, like coal, oil and gas. So it’s no surprise that we need to cut back on this habit - but much of the discussions are over how much of our reserves countries can continue to burn. Earlier this year, a landmark report from the International Energy Agency said there must be an immediate end to new fossil fuel exploration, and that current production must drop by 75% by 2050 if we are to stay within emissions targets. Daniel Welsby from UCL talks to Gaia about his just published massive analysis of fuel reserves and extraction. His study doesn’t go as far as the IEA’s, but still says that 60% of the remaining oil and gas, and 90% of coal reserves must stay underground if we are to keep below that 1.5C temperature rise. Natural gas, or methane, has a much stronger effect on temperature than carbon dioxide, but because it doesn’t last very long in the atmosphere before converting into carbon dioxide, it’s been a bit overlooked by governments. Two recent reports, from the IPCC and the UN, have pointed out that cutting methane emissions would be a quick win in reducing global heating. Most of our methane emissions are because of leaks from the oil and gas industry, or from landfill sites and agriculture. Gaia discusses tackling methane with Drew Shindell, of Duke University in North Carolina, the author of the Global Methane Assessment from the UN Environment Programme. Climate change is already having an impact on life everywhere. We’ve all seen the powerful pictures of polar bears on melting ice, but global warming is also causing problems for species in the tropics. Dani Rabaiotti of the Zoological Society of London explains how climate change is having an impact on African wild dogs, a species which is already endangered. This week the Human Fertilisation and Embryo Authority A recommended that the time limit for using frozen eggs, sperm and embryos, should be extended from 10 years to 55 years. Shahnaz Akbar, a fertility expert at Luton and Dunstable Hospital, explains what has changed in the science of preserving eggs from when the law was originally passed.

Rugby and the brain

Victoria Gill talks to Professor Damian Bailey who's leading research at the University of South Wales into the potential risks to brain health in contact sports players, from impacts to the head and body sustained during play. His latest study found that over the course of a 31 game season, the brains of members of a professional rugby union team underwent measurable changes, particularly the forward players who sustained most tackles, knocks and falls. The findings may help to identify why professional players of some contact sports are at an increased risk of dementia later in life.

Window to solve pandemic origins closing

Virologist Marion Koopmans is one of the independent researchers appointed by the World Health Organisation to investigate the origins of the coronavirus pandemic. The team visited China in January this year as a first step to answer how, when and where SARS-Cov-2 first infected humans. Professor Koopmans tells Victoria Gill that time is beginning to run out to launch the next phase of studies, to trace the first people in China to be exposed and identify the animals from which the virus jumped the species barrier. Also in the programme:Is the practise of feeding the birds in our gardens creating losers as well as winners, and causing the numbers of some woodland birds to decline? Conservation biologist Alexander Lees visits Victoria in her garden to discuss the question, and reveal the truly dark side of the Great Tit.A new study of the impact of street lighting on nocturnal insects shows that the local impacts on moths can be dramatic. According to entomologist Douglas Boyes, street lights deter female moths from laying their eggs and make them more vulnerable to predation by bats.

Covid 19 – reaching the unvaccinated

In the UK we have seen a recent fall in Covid 19 cases. Good news, but we don’t know yet if this will be sustained. The virus is now thought to be spreading predominantly amongst the under 30s, most of whom remain unvaccinated. Young adults are the demographic most likely to be vaccine hesitant or vaccine averse. Kavita Vedhara from Nottingham University discusses the delicate balancing act of managing personal choice and collective responsibility needed to persuade people to get vaccinated to help stop the spread of the virus.Forget lab rats, how about lab cats? Leslie Lyons from the University of Missouri says we’ve long neglected the genetic similarities between cats and humans.

A life-changing database

Proteomes, the sequences of protein within the DNA of every living thing, are notoriously difficult to model. The usual chemical methods can take months, but a new computational model using the ability of artificial intelligence to learn the complex sequences is able to predict structures within a matter of hours. Thousands of protein structure predictions are now available on a public database for anyone to access. Understanding such proteins is seen as key to treating nearly all disease. It also hold the potential for improvements in fields as diverse as increasing crop resilience to climate change and biodegrading plastic on an industrial scale. Marnie Chesterton speaks with Demis Hassabis from Deepmind which developed the protein structure prediction system, and Janet Thornton from the European Bioinformatics Institute which holds the database.Genetic engineering, the promise and perils, is the subject of a new series with Matthew Cobb on Radio 4, called Genetic Dreams, Genetic Nightmares. He tells us about the dilemmas now faced by researchers who on the one hand have the potential to send terminator genes into malaria spreading mosquitoes – but who are also aware of the huge unknowns surrounding the release of such technology.Extreme weather events are becoming more frequent. Hayley Fowler has been researching the links between weather systems, climate change and the heat and floods we are currently experiencing.And could we reduce the incidence of SARS-Cov2 with a different vaccination strategy? Julia Gog has modelled different scenarios, as the number of infections continues to rise. A strategy to target those who are mixing the most, whether socially or through their employment, may be more effective than one targeting the most vulnerable.

Covid19 - should we test everybody ?

Epidemiologist Julian Peto is advocating mass testing as the key part of a plan to stop the virus spreading. Studies where everyone has been tested have picked up asymptomatic cases. With the addition of isolation and contact tracing this method of testing has been able to massively reduce the spread of the virus. The hope is such a coordinated scheme implemented nationally could help bring the numbers down.There’s a question over which type of test is best to use for mass testing. At the moment many of us do lateral flow tests at home. Although they give instant results their accuracy has been shown to be strongly linked to how well the tests are conducted - hence the need to back up any positive findings with the more accurate PCR test. PCR takes longer and needs sophisticated lab equipment. However a compromise could be to use RT Lamp tests, they are accurate, give results in around 20 minutes, do require a very basic lab, but without the expensive equipment of PCR. A number of RT lamp tests have now been developed for SARS-Cov2. Kevin Fong has been to see the developers of one of them, the OxLAMP test. And with the lifting of restrictions how are you going to judge your own personal risk from Covid? It’s a question that interests philosopher of science Eleanor Knox. She says government mandates on mask wearing and social distancing have allowed us to avoid tricky questions around our own potential risk from the virus and risks our own behaviour might pose to loved ones. Now there’s a lot more to think about in terms of balancing our desires to return to some semblance of normality while levels of Covid infection continue to rise. One area that’s come into sharp focus over lockdown is exercise. Some people have been unable to exercise due to Covid restrictions while others have discovered a whole new interest in moving more. A new book ‘Move’ by Caroline Williams explores the links between brain function, evolution and movement. She says staying active is a fundamental part of what makes us human.

Covid and our ancient ancestors

A global project looking at the genomes of over 2 million people has found a number of distinct genetic markers which seem to either make Covid infection more likely or the symptoms more severe. Some of these markers are known to be associated with susceptibility to cancer and lung disease. However the researchers say on their own these genetic factors are not determinants of how sick people will become. Underlying health, age and sex and a range of environmental and social factors are likely more important says Andrea Ganna from Finland’s Institute of Molecular Medicine who crunched the numbers.The Royal Society Summer Exhibition has just opened. And this year its an opportunity for more people to get involved than ever before – the event is taking place online. There are a number of workshops and interactive games. We speak to a couple of the participants. Caroline Orr from Teesside University talks about research using supercomputers to make microbes produce a range of biofuels that could replace petrol and diesel, and Tony Peyton from Manchester University tells us how the electromagnetic properties of materials are bring harnessed to improve mine clearance in former war zones. And we go to another exhibition, the Royal College of Art graduate show, and ask the age old question - is it art ?

Gene editing gets real

For the first time the gene editing technique CRISPR has been used by injecting the CRISPR instructions into the bloodstream rather than directly into the affected organ. In a trial, six adult patients showed improvements after the treatment was used to prevent the expression of deformed proteins associated with a genetic disease. The hope is this method could treat a range of other genetic diseases, says Megan Molteni from Stat News.In the near future domestic gas boilers may be replaced by heat pumps. However, a district heating system in London is already installing the pumps in a scheme which should see 50% reductions in their carbon emissions.

And why watermelons, wildflowers and pollinating insects can benefit from less attention. Evidence from Florida on how reducing methods associated with intensive farming chime with initiatives here in Britain to replace grass verges with banks of wildflowers.

UK science policy shake-up; Ivermectin & Covid; black fungus in Indian Covid patients; many hominins in Siberian cave

The Prime Minister has announced his desire for the UK to become a 'science superpower'. A new office within the cabinet to look at science will work alongside existing science strategy and funding structures. So far it's unclear where the responsibilities between the various science policy bodies lie. James Wilsdon, Professor of Research Policy at the University of Sheffield, helps Gaia Vince pick her way through the spaghetti of overlapping organisations and Dame Ottoline Leyser, UKRI Chief Executive, gives her her take of the impact of the reorganisation.A major new trial has been announced into the effectiveness of the drug Ivermectin for the treatment of Covid-19. There's controversy surrounding the drug, which was designed to kill parasitic worms. It showed some promise against the virus in very limited lab studies. For many reluctant to vaccinate these studies seemed to suggest an alternative way to treat the virus. However, regulatory bodies disagree. It's hoped the new study and a range of other wide scale trials will give a more rounded view on the potential if any for Ivermectin as a Covid 19 treatment. Jack Goodman from the BBC News Misinformation Unit has been looking at the controversy surrounding Ivermectin. Scientists researching it have been subject to abuse and in some countries it has been rolled out as a treatment despite the lack of evidence on its effectiveness. There have been reports of a number of cases of Black Fungus in patients with Covid-19 in India. What exactly is this unusual but life threatening fungal growth? Dr Nitin Gupta, Assistant Professor in Infectious Diseases at Kasturba Medical College in Manipal, South West India, explains why this previously rare infection is now on the rise.. Gaia Vince talks to Elena Zavala of the Max Planck Institute for Evolutionary Anthropology, Leipzig, Germany about how she and her team have managed to extract DNA from samples of earth from the Denisovan cave in Siberia. Some years ago fragments of bone recovered from the cave revealed a new hominin species, called the Denisovans. Now DNA analysis of the layers of earth built up over hundreds of thousands of years are painting a picture of the vast variety of early people who used the cave, which included Neanderthals and early humans as well as Denisovans.

Cov-Boost trial; SARS-Cov 2 infection in action; sapling guards; why tadpoles are dying

Scientists are now looking at the question of third doses of vaccines against SARS-Cov2, and this week the Cov-Boost trial was launched. It’s being run from University of Southampton and is going to be using seven different vaccines, some at half doses, in people over the age of 30 who were early recipients of their two doses. The Chief Investigator, immunologist Professor Saul Faust explains the aims of the trial.Once we've breathed the coronavirus into our lungs, how does it spread through our bodies, despite our immune defences? Remarkably, scientists have managed to film the virus in the act of infecting lung cells and spreading between them. They then added some antibodies and watched what happened. Alex Sigal of the Africa Health Research Institute tells Gaia Vince what they saw.The UK government has pledged to plant some 2 billion trees to help get us to net zero – and that’s an awful lot of plastic casing to be littering the countryside with. A team at the Institute of Making at UCL decided to look at the overall environmental impact of these tree protectors. This is quite a complicated calculation as it involves looking at the entire life cycle of the trees and the plastic, including the carbon and water and energy used. Gaia finds out from Charnette Chau, the life cycle assessment expert on the team, and Professor Mark Miodownik what they found. Across the US, people have been reporting ponds full of dead tadpoles: mass mortality events. It seems that a parasitic infection previously associated with disease in marine oyster populations, may be to blame: severe Perkinsea Infection. The big fear is that it will spread further, to places like Panama in Central America, which has seen such a drastic decline in frog populations that researchers have begun captive breeding some species as “assurance populations” to protect them from extinctions. Tom Richards, Professor of Evolutionary Genomics at the University of Oxford, reports on what he discovered when he went to Panama to see if the infection had reached its precious hoppers.

Covid vaccines in children; preventing dengue; algal blooms; supersonic flight

Should we be vaccinating children in the UK against SARS-Cov 2? Children are rarely seriously ill if they catch Covid but infections mean missed school, and they can pass it onto older vulnerable people. The US, Canada, Israel and Dubai are some places that are already vaccinating the under 18s and Pfizer has recently published data from a trial of its mRNA vaccine in just over 2000 12-15 year olds, showing no safety concerns. Gaia Vince discusses the issue with Professor Beate Kampmann, consultant paediatrician and Director of the Vaccine Centre at the London School of Hygiene and Tropical Medicine.Dengue fever is a widespread tropical disease caused by a virus spread by the Aedes aegypti mosquito. Until now, there’s also been no way of preventing dengue aside from trying to get rid of mosquitoes, which is pretty tricky. Gaia hears from the World Mosquito Programme’s Dr Katie Anders about some positive news from a large trial in Yogyakarta in Indonesia, where mosquitoes infected with a harmless bacteria called Wollbachia, were deliberately released. The researchers found a 77% drop in cases of dengue in the areas where the infected mosquitoes were released. Hospitalisations were 84% lower.This week the first attempt to map algal blooms globally has been released, and it also charts how blooms have changed over the last thirty years. And the news isn’t good. Henrik Enevoldsen of the UN who’s based at the University of Copenhagen, has spent thirty years studying these phenomena and he explains how the growth in aquaculture has had an impact on the rise of algal blooms in some parts of the world.Nearly twenty years after Concorde last flew, a company called Boom is promising to bring back supersonic passenger flights in the next few years.

Lab origin theory of SARS-Cov2; gene for obesity; dark matter map; rock art in Scotland

Sars Cov2, as the Covid19 coronavirus is called, probably began as the vast majority of new diseases do, when an animal virus infected a person – perhaps in a market or farm. There’s a large animal market in the city of Wuhan that sold wild as well as farmed animals, and studies have shown that different species of animals can infect each other with coronaviruses on their journey to market. But there’s also a possibility that the virus originated in one of two government laboratories in Wuhan. After all, we know that other viruses have escaped from labs, including the original Sars virus, which escaped multiple times from different Asian labs. Jonathan Ball, Professor of Virology at the University of Nottingham, discusses with Gaia Vince why the lab leak theory is again in the news.We know that obesity runs in families but because parents and children live in the same environment and eat the same food it is difficult to tease out how much of this relationship is inherited genetically. Researchers at Cambridge University have been working with the Children of the 90s cohort of people based in Bristol, and they’ve have found that a mutation in a single gene drives obesity in some families. The gene in question is called MC4R. Professor Stephen O’Rahilly, who is one of the researchers, explains that the mutation is remarkably common and has a significant impact on individuals, from an early age.Last week, researchers released the biggest and most detailed map of how matter and dark matter have spread across the universe since the Big Bang. The problem, is that the dark matter is more smoothly distributed than expected according to Einstein’s theory. Some are now saying physics is broken. Was Einstein wrong? Astrophysicist Catherine Heymans, who is a Dark Universe expert, and has just been appointed Astronomer Royal for Scotland, the first woman to hold the role, talks about the implications of the new map of dark matter and her plans to encourage the public to appreciate the night sky. For the first time figurative rock art over 4000 years old has been discovered in Scotland. Up till now all that’s been found have been marks such as cups and rings. The new images are detailed portraits of deer, with antlers, on a capstone of a burial mound, or cairn, in Kilmartin Glen on the west coast. It’s a well-studied archaeological site but the rock art hadn’t been spotted before. Gaia asked Tertia Barnett, Principal Investigator for Scotland’s Rock Art Project at Historic Environment Scotland, about who may have produced this art.

Human use of plants beyond the limits of history.

Human impact on planet earth’s plant life might be detectable several thousand years back in fossil pollen cores taken from mud columns around the world. As Suzette Flantua and Ondrej Mottl describe in a paper published in the journal Science, a rapid acceleration in the changes in pollen species goes back further than we might have expected. This matters particularly when it comes to decisions around re-wilding and re-planting areas today in the name of conservation. As they hope to build on in future work, learning more about the state of ecosystems further back into the past might prevent us making the mistake of simply recreating different types of post-agricultural situations which might not solve the problem we are trying to fix. One of the biggest impacts on the earth’s flora today is of course influenced by our meat consumption. The BBC’s Melanie Abbott has been to see a new exhibition opening at Oxford University’s Musuem of Natural History. Produced in association with the University’s Livestock, Environment and People research programme, this exhibition “Meat the Future”, seeks to raise awareness of the issues for health and the environment around eating – or not eating meat - and is open until January 2022. At the same time, a travelling interactive experience called Meat Your Persona will be moving around the UK, starting in Cardiff. And there's an online interactive questionnaire you can try from home. See the links at the bottom of the BBC Inside Science programme page. Researchers in the US are working on devices that might be able to connect with people’s brains to allow them to manipulate robotic or digital devices to regain abilities lost to disease or injury. As Dr Frank Willett and Prof Krishna Shenoy - both at Stanford University’s neural prosthetics translational laboratory - describe in the journal Nature, they have managed to create a device that allows one patient to create text using just thought. Rather than trying to guide a cursor over a keyboard, their technique works by learning which letter the patient is thinking of drawing by hand, despite being unable to wield a pen.And Jacob Dunn, associate professor at Anglia Ruskin University describes his team’s work which finds that tamarin monkeys will use the “accent” of another species when they enter its territory to help them better understand one another and potentially avoid conflict. His paper, published in the journal Behavioral Ecology and Sociobiology, describes findings in the Amazon rainforest near Manaus where a species that ordinarily use quite distinct long distance calls subtly change their call to sound more like a neighbouring species’ equivalent call when they are sharing the same area of forest. Not so much an aggressive intrusion as a polite lingua franca, it may be that the shared understanding reduces unnecessary and costly territorial fights between the two species.Presented by Victoria Gill Produced by Alex Mansfield

Blood Clot Cure, Synthetic Fuels and Coal Mine Heat Pumps

Vic Gill talks to scientists who have cured a vaccine-induced blood clot patient, and meets a former top F1 chief engineer who wants to transform the fuel industry.Scientists in Vienna have been continuing to look at the rare blood clots associated with the AZ Covid-19 vaccination. Paul Knoebl describes to Vic his paper describing the diagnosis and successful treatment of a patient who developed a fever whilst skiing six days after taking it. Whilst the side effect is still condsidered incredibly rare, Paul tells Vic that a relatively simple cure - after early diagnosis - should remove any lingering hesitancy of taking a vaccine.The Science Museum reopened this week with a new exhibition looking at the science of Carbon Capture. Inside Science took former Formula One technical champ Paddy Lowe to have a look round. He is interested in Carbon Capture because he has started a new company - Zero Petroleum - that aims to do nothing less than kick start a synthetic (hydrocarbon) fuel revolution. Using carbon dioxide captured from the atmosphere, he and colleague Prof Nilay Shah believe they can use renewable electricity and other feedstocks to tranform captured carbon into fuels, and create a whole new petrochemical supply that could close the loop on the industrial revolution - especially for those energy uses where batteries could not currently work, such as jet engines and heavy remote machinery.Meanwhile, up in the north east of England, Charlotte Adams of the UK's Coal Authority describes progress on measures to convert disued Coal mines to geothermal heatpumps, providing reliable steady heating for new-build homes across many parts of the UK, and taking strain off the elictircal grid.Presenter Victoria Gill Producer Alex Mansfield

Microplastics in UK river beds

Untreated wastewater "routinely released into UK rivers" is creating microplastic hotspots on riverbeds. That is the conclusion of a study in Greater Manchester, which revealed high concentrations of plastic immediately downstream of treatment works. The team behind the research concluded: untreated wastewater was the key source of river microplastic. Jamie Woodward takes Vic Gill wading in the River Tame in Greater Manchester to show some of the sites they studied, while co-author Rachel Hurley talks from Norway on the wider global questions of where microplastics get into our environment and what harm they do. The origin and location of the radioactive pollution that so devastated the lives and livelihoods of those affected by the Chernobyl disaster 35 years ago is not a mystery. But recently it has become apparent that in one small inaccessible room within the massive sarcophagus at the ill-fated power station, the nuclear fission still happening is getting slightly faster. As Neil Hyatt describes to Vic, the reason may be because the new concrete shell, unlike its predecessor, is doing a better job at keeping the rain out, and nothing to worry about for the time being. Meanwhile, Jim Smith and colleagues have been trying to demonstrate that agricultural products could help the besieged economy of surrounding areas. Using apples grown in regions where investment is illegal, they have developed a spirit drink - called Atomik - with which they hope to demonstrate a viable market outside of the Ukraine, perhaps providing jobs and export business, and maybe even useful profit with which to help the area. And finally, Dr Kim Dienes describes from Swansea the health and psychological benefits of something so many hundreds of millions of people in the world have been missing this year: a nice hug.Presenter: Vic Gill Producer: Alex Mansfield Assistant Producer: Samara Linton.

Early burials, diversity in Tudor England, a malaria vaccine, and rogue brain waves

Despite being home to our early ancestors, attempts to find evidence of early burials in Africa have proved unsuccessful. That is until now. Professor María Martinón-Torres explains how findings from a 78,000-year-old Kenyan grave shed light on how our ancestors related to the dead. In keeping with the theme of clues from the past, Cardiff University academics have been studying the remains of crew who drowned on King Henry VIII’s favourite ship, the Mary Rose. As it turns out, Tudor England was more ethnically diverse than we previously thought. Victoria Gill speaks with University of Oxford researcher Dr Mehreen Datoo about a promising new malaria vaccine which was shown to be 77% effective in early trials.

A new report that has measured the state of over 200 000 of the world's glaciers has just been published. Bob McNabb of the University of Ulster explains why it's not good news as glaciers are melting at a faster pace than before. He says it could have a particular impact on people who live in low lying areas.At the start of April cases of the South African variant of SARS-Cov 2 were found in a number of London boroughs. In order to stop the further spread of these variants, a programme of surge testing was announced.

Coronavirus variants and vaccines, climate change resistant coffee, dare to repair and how to get rid of moths

This week has seen a huge surge in Covid- 19 in India leading to concern of a "double mutant" variant, but what do we know about this B.1.617 as it is otherwise known. It was first described in October and is now in other countries including the UK. Virologist Dr Muge Cevik looks at the emerging evidence around vaccines and new variants. Climate change threatens coffee crops so it's exciting to know that researchers have found an ancient coffee variety that is drought resistant and can tolerate higher temperatures than the highly prized Arabica coffee used to make your latte - but it wasn't easy to find. In Sierra Leone Daniel Sarmu spent 4 years searching for it and Dr Aaron Davis from Kew helped to track it down using historic samples from the Herbarium at the Royal Botanic Gardens.Clothes moths do enormous damage to our jumpers and carpets, Marnie finds out how best to protect your clothes. And we hear from Mark Miodownik about the right to repair.

Blood clots, grieving and the emotion of screams

The story of what we understand about the rare cases of blood clots associated with certain Covid-19 vaccines is constantly evolving. In today’s programme Professor Beverley Hunt looks at the emerging evidence.How have the restrictions due to Covid 19 affected how we grieve? Professor Claire White, an expert in grief and mourning, is investigating what it means to the grief process when the traditional ways of acknowledging death are changed.Sascha Fruholz has the unenviable task of listening to people scream all day, but he has made some surprising discoveries about which types of scream people are best able to identify.

Disobedient particles, noisy gorillas, sharks and fictional languages

In 2016, an accelerator physics centre called Fermilab acquired a massive circular 50 foot magnet from a lab in New York. Too big for the roads, the magnet had to take a 2000km detour via New Orleans to get to its new home. This was the start of the “muon g-2” experiment. Last week, Fermilab announced some of their results, and they don’t quite add up. UK experiment lead Professor Mark Lancaster from Manchester University tells us what they have discovered about the tiny particle that is disobeying the laws that govern how our entire universe fits together.Mountain gorillas are among the most impressive and powerful primates alive today. Living in the dense forests of eastern and central Africa, they are able to communicate with other gorillas a mile away by cupping their hands and beating their chests. Primatologist Edward Wright and colleagues have been studying male silverback gorillas and explains how gorillas use chest beating to attract potential mates and suss out competitors. And Professor Corey Bradshaw from Adelaide, South Australia sheds light on a more fearsome animal: sharks. His research has investigated the likelihood of shark attacks around the Australian coast into the future, up to 2066, and asked what would happen to those figures if everyone wore an electrical emitter that interferes with the sharks electrical senses. He finds that shark attacks are remarkably low already, but these emitters could reduce bites by up to 3000 over the next 50 years. Super fans around the world have learned to speak fluent Klingon, a fictional language originating from Star Trek. In a quest to understand the science behind these languages often dismissed as gobbledygook, Gaia Vince has been speaking to some of the linguists responsible for creating these languages.

Science funding cuts; Mice get Covid-19; Native oyster reintroductions

Scientists were delighted earlier this year to find they would still have access to the EU Horizon 2020 funding and collaborations. Now, it has been revealed that membership of this group, which was previously paid for through fees to the European Union, may come directly from the science budget, at a cost of about £15 billion over the next 7 years. That’s £1-2 billion a year. Marnie Chesterton speaks with Beth Thompson, head of policy at the Wellcome Trust about the implications, and Roland Pease asks scientists working around the world how the previously announced ODA cuts are affecting their work. Native oysters help to filter coastal waters of the UK of pollutants including nitrates, while also providing habitat for other species. But their numbers have declined by 95% throughout their British range. Now, the Zoological Society of London is placing thousands of mature oysters under pontoons in marinas across the UK to let them breed, and encourage the return of the species to their former numbers. And the new coronavirus mutations that are worrying us all have been found to affect mice in experimental studies at the Pasteur Institute in France. Marnie asks if this change to the infectivity of the new variants has implications for human health and our ability to combat the virus. Presented by Marnie Chesterton Produced by Rory Galloway

Halfway to net zero; hydrogen as a fuel; Fagradalsfjall, Iceland’s active volcano

The UK is reportedly halfway towards meeting its 2050 target of "net zero" carbon emissions. How did we get there and how will we achieve the next stage? ‘UK greenhouse gas emissions in 2020 were 51% below 1990 levels, according to a new Carbon Brief analysis. This means the UK is now halfway to meeting its target of “net-zero” emissions by 2050.’ Simon Evans explains his predictions from the report, outlines how we define net zero and what is required from the next few decades to ensure that the UK meets its 2050 goal. Much of Europe is attempting to replace fossil fuels, transforming transport and domestic heating to run on electrical alternatives, such as batteries and heat pumps. But where electrification isn’t possible or cost effective, such as in many homes, an alternative is still needed. Natural gas is responsible for over 30% of the UK’s total carbon emissions. Hydrogen would, theoretically, appear to be the perfect alternative, as combustion only produces water as a by product. Gaia discusses the options with hydrogen strategist, Dr Jenifer Baxter, and Dr Angela Needle of Cadent explains the pilot projects the company is carrying out to introduce 20% hydrogen into gas going into our homes. Last Friday, Fragradalsfjall began erupting for the first time in 800 years. The volcanic system is located in the West of Iceland close to the capital city of Reyjkavik. Dr Evgenia Ilynskaya of Leeds University has been out measuring the gases emitted by the eruption and she describes the experience of working on an active volcanic system.

Human embryo research and ethics; sperm whale social learning; Antikythera mechanism

We still know very little about exactly how the embryo forms out of a mass of dividing cells in those crucial first weeks after conception. This is also the time when many miscarriages occur, and scientists want to understand why. Couples going through IVF donate spare embryos for research and scientists are permitted to study them in a test tube, or in vitro, allowing them to grow and develop for up to 14 days. This 14 day rule is abided by globally, and it’s enshrined in the Human Fertilisation and Embryology Act in the UK. Thirty years ago no-one could keep these embryos alive for more than a few days but recently the techniques have moved on and they have been cultured for nearly 14 days. So should the 14 day rule be extended? Gaia Vince discusses this question with bioethicist professor Insoo Hyun of Case Western University and Harvard Medical School.There are other ways of studying this early development that don’t involve growing an actual embryo, and that’s by using just a few stem cells from it. These are cells that haven’t yet specialised into any type of body cell and so they have the potential to become any cell type. Researchers can grow these cells into structures that resemble embryos, although they could never survive inside a woman’s womb, and these artificial embryos aren’t subject to the 14 day rule. Gaia talks to Dr Naomi Moris of the Crick Institute in London about her work on what she calls gastruloids.Whaling was a huge industry in the 19th century, and populations of sperm whales plummeted, as hunters sought the oil in their heads that was used everywhere for lighting. The whalers who were hunting in the North Pacific kept meticulous records that have been recently made public. Biologists have been studying them, and picking out unexpected changes in the patterns of whale capture. Dr Luke Rendell of St Andrews University explains how he and his colleagues worked out that that the whales seemed to be learning from each other how to avoid the boats. A piece of intricate Ancient Greek engineering called the Antikythera mechanism, that was found by sponge divers in 1901 in the Mediterranean, has fascinated many people. Last week a team from University College London published the latest explanation of how the device worked. Science writer Jo Marchant herself became so obsessed with the mechanism that she published a book on it called Decoding the Universe and she talks to Gaia about the object and what the new research tells us about how the Greeks understood the cosmos two thousand years ago.

China's green growth plan

On Friday 5th March China published a draft for its 14th five-year plan in Beijing. The document acts as a national economic blueprint and was expected to provide an outline as to how the world’s biggest emitter of greenhouse gas emissions planned on tackling its target of reaching net zero emissions by 2060, put forward by President Xi Jinping last September. It appears that greenhouse emissions could continue to increase by 1% or more each year up until 2021. Sam Geal, acting CEO at China dialogue, explains how influential Chinese efforts are when combatting climate change. Since the late 1980s conservationists have used captive breeding to prevent the extinction of North America’s only native ferret species, the black footed ferret (Mustela nigripes). Now, an individual called WIlla, who died without leaving any offspring over 30 years ago has been cloned. Her genes represent 300% of the current genetic diversity of the species, and could help boost the chances of these animals. Dr Bridget Baumgartner works with one of the teams that took part in the successful cloning project, she describes how this novel process could bolster and prop up the genetic diversity of the dwindling population. How does one get a closer look at nutrient cycling and water temperature in marine Antarctic conditions? You could always recruit some of the local inhabitants, elephant seals! That’s exactly what Yixi Zheng at the University of East Anglia did. Her furry research assistants have revealed that surface water temperatures around the ice shelves and glaciers of Antarctica are warmer than expected in winter, and this holds implications for nutrient cycling and the productivity of the southern ocean. And finally, after an ancient rock seized the attention of the residents of Winchcombe in Gloucestershire, Professor Sara Russel discusses the rarity of finding meteors here on earth, let alone finding one early in the morning sat on your driveway. We hear what the nearly 400g of space rock that's been found this week could reveal about the origins of our solar system.Presented by Gaia Vince Produced by Rory Galloway This programme was made in association with the Open University.

Blue carbon; inside Little Foot's skull; reading locked letters

With global warming continuing to increase at an alarming rate, we need all the help we can get to lock up the carbon that we’ve released into the atmosphere. Fortunately, plants have evolved to do just this, but there’s a whole class of plants that often get forgotten: the mangroves and seagrasses that grow between land and sea, which are among the planet’s most effective carbon sinks. Gaia Vince talks to Fanny Douvere, head of the marine programme at UNESCO, about its new report that shows the importance of blue carbon locked up in its marine World Heritage Sites. And Professor Hilary Kennedy, of Bangor University, explains why seagrasses are so effective at locking up carbon. Roland Pease reports on the secret journey made by one of the most valuable of human fossils, Little Foot, from Johannesburg to Oxfordshire, where it was scanned at the Diamond Light Source facility – one of the most powerful X-ray machines in the world. He talks to some of the main players about the hush hush voyage, and what they’re hoping to discover.There are few things more intriguing than an unopened letter, but what about one from 300 years ago? The Brienne Collection is a Postmaster's trunk containing more than 2000 letters sent to the Hague between 1680 and 1706, and more than 600 are still unopened. In the days before envelopes, people used elaborate folding techniques to secure letters, even tearing off a bit of paper and using that to sew the letter shut, effectively locking it. It makes reading those letters very tricky indeed, especially as antiquarians don't want to risk opening them. Instead, researchers hatched a plan to scan the letters in their untouched, still folded state, and generate a 3D image of their insides of such detail it could be used by an algorithm to unfold it virtually. David Mills from Queen Mary University London tells Gaia about how he used a microtomography scanner to peek inside the unopened letters. Presented by Gaia Vince.

Good COP Bad COP, Shotgun Lead Persistence, and Featherdown Adaptation

On Thursday, The UN Environmental Programme published a report called Making Peace With Nature. It attempts to synthesise vast amounts of scientific knowledge and communicate “how climate change, biodiversity loss and pollution can be tackled jointly within the framework of the Sustainable Development Goals”. But it also offers clear and digestible messages that governments, institutions, businesses and individuals can act upon. Concluding BBC Inside Science’s month-long look at some of the challenges ahead of COP26 in Glasgow later this year, and its sister biodiversity meeting in China, Vic speaks with the report’s co-lead Prof Sir Robert Watson FRS and the Tyndall Centre’s Prof Rachel Warren, also a contributing author. Can all the ills of the natural world really be tackled at once?Game-shooting, for sport and food, has traditionally used the toxic metal lead for ammunition. In other parts of the world its use has been banned for the dangers to the human food chain and to the pollution in natural environments, and even deaths of wildfowl from poisoning. But not so in the UK. A year ago, as reported on Inside Science at the time, the shooting community announced a voluntary five year transition period to alternative shot materials. But researchers including profs Rhys Green and Debbie Pain from Cambridge University have discovered that a year on, little seems to have changed. Gathering game sold for food across the UK, they found that all but one bird in their sample of 180 contained lead shot. Meanwhile, up in the Himalayas, Smithsonian scientist Dr Sahas Barva was enjoying the scenery on a cold day off in 2014 when he saw and heard a tiny Goldcrest, thriving in temperatures of -10C. Wondering how such a tiny thing could keep its body insulated, he decided to investigate feathers, and utilizing the huge numbers of specimens in the Smithsonian’s collection he found some striking commonalities in the thermal properties and adaptations of birds everywhere. The higher up they live, the fluffier their coats.Presented by Victoria GillProduced by Alex MansfieldMade in association with The Open University.

Nasa's Perseverance - will it pay off? And spotting likely hosts for future pandemics.

On Thursday 18th Feb 2020 Nasa’s Perseverance Rover is due to touch down – gently and accurately – in the Jezero crater on Mars. Using similar nail-biting Sky Crane technology as its predecessor Curiosity, if successful it will amongst many other things attempt to fly the first helicopter in the thin Martian atmosphere, and leave small parcels of interesting samples for future missions to collect and return to earth. Unlike previous Martian landings of course, there are no mass-landing parties to be held because of Covid. So Vic Gill invites you to join her and current Curiosity and future Rosalind Franklin (ESA’s 2023 Rover) team scientists in nervously awaiting the signal of success.Dr Susanne Schwenzer was so tense during Curiosity’s final approach in 2012 that she managed to draw blood from her own hand from clutching her mobile phone too hard. BBC Inside Science expects nothing less this time round. Dr Peter Fawdon has been part of the team seand examining the landing site for ESA’s Martian lander and Rover, currently slated to launch in 2022. The project has had a complicated history, having been delayed several times. But with so much at stake, it’s worth getting right. Meanwhile, at Liverpool University, computer scientist Dr Maya Wardeh and virologist Dr Marcus Blagrove have been collaborating to see if Machine Learning and AI can help predict which mammalian species are more likely to harbour the next big coronavirus. Pitting traits and genomes, species similarities, lifestyles and ecosystems of mammals and viruses, they highlight in a paper published in Nature Communications some of the potentially most potent combinations where different coronaviruses could meet and spawn a new breakout. Not just looking for the more quotidian viral mutations the world is increasingly and unfortunately aware of, they have been looking instead for those species where something called homologous recombination between two different viruses, producing a third completely novel type, may occur. It turns out there are many possibilities beyond just bats, which are highly suspected of being the crucible in which SARS-CoV2 was smelted. To spot whatever comes next we should keep an eye on camels, rabbits, palm civets and even hedgehogs, according to the algorithm.Presented by Victoria Gill Produced by Alex MansfieldMade in Association with the Open University.

Meeting Mars, Melting Ice, Ozone on the Mend Again, and A Sea Cacophany

Victoria Gill and guests discuss the signs and symptoms of melting ice and anthropogenic climate warming, illicit CFC production and the racket we make in the seas. As two robotic missions from UAE and China arrive at Mars , and a third from NASA arrives next week, UK astronaut Tim Peake talks of the international collaboration in Mars research that is to come. And continuing BBC Inside Science's look at some of the issues facing COP26 delegates to Glasgow this autumn, Victoria is joined by cryosphere scientist Dr Anna Hogg,Anna studies – sometimes from space - how polar and Greenland ice sheets are melting and shifting as our climate warms. But those giant volumes of ice and concomitant rising sea levels might not be the only threat to people’s lives. It may be that the recent deadly flash flood in India was a result of a swiftly melting Himalayan glacier.The Montreal treaty - prohibiting the production of CFCs to allow the man-made polar hole in the Ozone layer identified back in the 1980s to repair - has long been cited as the classic example of an effective international agreement to protect earth's environment. But just a few years ago in 2018 Luke Western and colleagues identified not just that CFC production was suddenly and unexpectedly rising, but that it was mainly emanating from an area in eastern China. It was speculated then that their use in foams for buildings was happening illicitly on a large scale. This week, they happily announce that those emissions seem to have ceased, and that the target of a healthy ozone layer is back on track.The oceans are, since man first took to the waves, a noisy place. In a comprehensive paper published last week in the journal Science Carlos Duarte and colleagues describe how huge an impact the many anthropogenic noises that echo for miles across the sea beds have on virtually all aquatic life. He argues that it is one stressor, rather like CFCs, that we could and should take swift and effective action to address, that the time for that is ripe, and that doing so will see a swift rebound in many aquatic ecosystems. Humans are not naturally adapted to hear the noise underwater, but to illustrate the point, co-author digital artist Jana Winderen has made an acoustic demonstration for your benefit, of quite how noisy neighbours we areAlso, for listeners on BBC Sounds, the BBC's Roland Pease gives an update on where and how scientists think the covid-19 epidemic began, after a WHO team of scientists report on their recent mission to Wuhan and the infamous market.

Putting a number on biodiversity

Ahead of the COP summit in Glasgow at the end of the year, this week an important study was published that attempts to enumerate the value of biodiversity in the economics of humankind. Prof Sir Partha Dasgupta's review makes it clear how essential and yet vulnerable it is.Trees play a large part in the biosystems of the planet, and replanting them is often touted as a solution to many of the carbon challeneges of the next century. But a paper and forthcoming conference hosted by Kew points out just how carefully reforestation - let alone afforestation - must be conducted.Kew tree expert Kate Hardwick tells Victoria about their 10 golden rules of planting trees.In a forest in Borneo, trees have been planted that will extract the high levels of Nickel from the local soil. It is hoped that the biomass from the trees can then be used to harvest the nickel. It is an attempt to commercialize successfully the dreams of "phytomining" - finding specific crops or traits in plants that can act to "hyperaccumulate" minerals and metals from soils. BBC Inside Science's Harrison Lewis reports how, after some intrepid botany, the idea might just now be bearing heavy fruit.But finding the plants that do some of what you want them to does not mean they should be planted just anywhere. Lulu Zhang from United Nations University in Dresden, Germany tells Victoria about the Chinese experience of a few decades ago when the Black Lotus tree seemed to be just the ticket for newly foresting huge areas of China to stabilize and neutralize soils. Unfortunately, nobody realized how thirsty the monocultured forest would be, and the thirsty trees deprived the area of much of the rainwater from humans and agriculture.Meanwhile this week scientists have published work looking at how even the noise from traffic on the roads can disrupt animal behaviour. Chris Templeton of Pacific University in Oregon has been studying how some bird's cognititve abilities can be affected. And Adam Bent describes work at Anglia Ruskin University into how crickets' mating choices can be adversely affected by recordings of the A14 near Cambridge.Presented by Victoria Gill Produced by Alex MansfieldMade in association with The Open University

Next Gen Covid Vaccines; Man's Oldest Bestest Friend; Bilingual Brain Development

A year after the first SARS-Cov2 sequences were received in the vaccine labs, Dr Alex Lathbridge and guests look into ongoing development and what next year's booster shots might be like. Prof Robin Shattock's team at Imperial College are still working on their vaccine technology - called 'Self Amplifying RNA' or saRNA. A little bit behind their well financed corporate colleagues, this week they announced that instead of pressing ahead with a phase III trial, they will instead look to developing possible boosters and alternative targets just in case more and more serious mutations happen. But as Prof Anna Blakney explains from her lab at University of British Columbia, the possibilities of saRNA don't stop with coronaviruses.Researchers in the journal PNAS report this week a new theory as to when and where dogs were first domesticated by humans, and suggest that they accompanied the first humans across the Bering straight into America. Inside Science's Geoff Marsh has a sniff around.And Dr Dean D'Souza from Anglia Ruskin University describes in Science Advances work he has done looking at certain kinds of development in children who grow up in bilingual households.

UK Science post Brexit; GMOs vs Gene Editing regulation; Identical Twins That Aren't Indentical

In the new EU-UK deal, the UK is to be an associate member of the latest EU research funding round, known as Horizon Europe. Costing around £2bn to take part, what can UK scientists now do and what has changed? UKRI CEO Otteline Leyser and the Wellcome Trust EU specialist Beth Thompson discuss ways in which UK researchers are breathing a sigh of relief.Of all the ways the UK can now diverge from the EU, DEFRA is currently holding an open consultation on whether to tweak the current GMO regulations so as not to include CRISPR-style Genetic Editing. The EU is coincidentally looking at the same issue. John Innes Centre's Janneke Balk works on making strains of wheat that have a higher level of iron for nutritional fortification. Interim head of the Roslin Institute in Scotland Bruce Whitelaw thinks developing disease resistance in farm animals is a potentially profitable area. Both agree the GMO regulations should be more tightly specified to bring clarity and opportunity for innovation. In Iceland, Kari Stefansson's company Decode Genetics analyze the genetic codes of most of the population of Iceland. This has allowed them to look at the parents, siblings, and offspring of identical twins, and identify how early genetic differences between them develop. And it's very early indeed. Given that identical twins studies are so often used to address issues surrounding the so-called Nature-vs-Nurture debate, the findings, published in the Journal Nature, are striking.

Vaccine Dosing and Biodiversity Soundscape Monitoring

After the decision by the UK government last week to change the spacing between dosings of vaccine from the recommended 3 weeks to 12 weeks, immunologists around the world have been discussing with some urgency the wisdom of such a move. The FDA and the WHO are deeply sceptical, and the manufacturers have distanced themselves to some extent, by cautioning not to deviate from the regime tested in last year's phase III trials. The thinking behind the move is to get more people injected with a single dose in a shorter time, and that the longer wait for the second shot is worth the risk, if it means more people receive some level of protection in the short term.Clinical Epidemiologist Dr Deepthi Gurdasani and Immunoligist Prof Danny Altmann of Imperial College describe to Marnie how evidence, experience and hunch are combining in the face of the covid crisis, and quite what we know, what we don't and what we could, about this nationwide experiment. Increasingly, ecologists wanting to monitor remote areas are relying on such things as solar powered audio recorders to measure biodiversity in the sounds of the wild. But how to scrutinize years and years worth of 24 hour, multi-site recordings?

Space Rocks, Aquatic Dinosaurs and Global Temperatures; 2020 science reviewed

Nobody could have failed to notice the one story dominating the science news this year - but what about the discoveries that have been overshadowed in 2020? This week, Dr Adam Rutherford eschews all mentions of the pandemic as he invites dinosaur researcher Dr Susie Maidment, climate scientist Dr Tamsin Edwards and astrophysicist Dr Emma Chapman to share their science highlights of the year. We journey to the moon and beyond to discuss the many missions that have been blasting and grabbing bits of space rock to bring back to earth and tackle the ongoing debate about whether signs of life have been found on Venus. Back down on earth, this year could be one of, if not the, hottest years on record, with particularly high temperatures in the Arctic Circle. What might a warming world mean for ice-shelf collapse in Antarctica and how are governments responding? We discuss Joe Biden’s presidency, UK carbon emissions and what China’s recent announcements of net zero by 2060 might mean for the future of the planet. And despite limitations on travel this past year, exciting discoveries in the dinosaur world have nonetheless continued with what is believed to be the first aquatic dinosaur. The detection of soft shell eggs is also changing understandings of how dinosaurs reared their offspring.And if that wasn’t enough, Dr Adam Rutherford challenges our experts to predict what big science stories might lie on the horizon in 2021.

Covid mutation; On the facial expression of emotions; A mystery object

Dr Alex Lathbridge with your peek at the week in science.This week in the House of Commons Matt Hancock announced a new variant in the Covid virus, discovered to be spreading through the south east of the UK. As Professor Jonathan Ball of the University of Nottingham describes, there have been many slight mutations and changes to the DNA in the virus since it first emerged, and most are of no added danger. But it is important that new ones - and new combinations of them - are tracked through collaborations and networks such as COG-UK, who provide an almost real-time track of the spread of new mutations. The new one this week is of some interest as it involves a slight change to the protein of the binding area on the virus, but much lab work remains to be done,Is an angry face always an angry face? A paper in the Journal Nature this week uses Machine Learning to scan millions of videos of faces on YouTube to shed light on an old problem - the universality of facial expressions in people. The authors - working with Google - suggest that broadly speaking, in a number of contexts such as weddings and sporting events, people in much of the world tend to pull the same faces. But as Lisa Feldman Barrett - who wrote an accompanying commentary in the same journal - suggests, the way Machine Learning approaches in this area require very human perceptions to train the algorithm in the first place, means care must be taken before inferring too much.This year BBC Inside Science has been showcasing some of the mystery objects the Science Museum has uncovered in the course of moving its collections to a new home in Wroughton, Wiltshire.

Future risk planning; Millennium Seed Bank; Urban trees

Dr Alex Lathbridge brings you the week in science.As the first COVID vaccines are delivered this week hastening the first glimmers of a return to normal life, is it too soon to be thinking about other future threats to humanity? James Arbuthnot, chair of a House of Lords select committee tasked to look at risk planning, and fellow committee member Martin Rees discuss their meeting this week and the assessment of the scientists invited to share their interpretations of future threats like AI, solar flares and volcanic eruptions. They are inviting evidence submissions until January 28th 2021.The Millennium Seed Bank was setup as a safety net to protect and conserve rare, threatened and useful wild plants for generations to come. As it celebrates 20 years of operation it can claim to host 16 per cent of the world’s bankable flora in its sturdy underground vaults. Alex heads down to the Royal Botanic Gardens in Wakehurst, Sussex, and meets the team coaxing seeds to life to check their viability or using cryopreserving on those seeds less convivial to being preserved. One key project is protecting farmed crops that have lost genetic diversity over time and are at risk from climate change. Through collecting and researching the wild ‘cousins’ of our modern day crops Wakehurst, Kew Gardens and its partners are researching and harnessing the resilient traits found in these less pampered crop relatives. is a citizen science project designed to increase understanding of all the urban tress in the UK. Scientists, together with the public, are getting their tape measures out and cataloguing the trees to better ascertain how they influence the environment in towns and cities across the UK, to map their ages, species, sizes and health, and to help future planners to put the knowledge to work. Kate Hand is a researcher at the Open University who is looking at ways to increase our knowledge of the values trees bring to our urban environments – specifically through the lens of Milton Keynes which, it transpires, is quite the urban arboretum.

Protein folding; Hyabusa sample return; Holiday Covid testing

Has one of the biggest problems in biology been solved by AI? Dr Alex Lathbridge brings you the week in science.This week google's Deep Mind team presented results of their latest efforts at cracking the 50 year old problem of Protein Folding. AlphaFold has built on previous success at predicting the 3D structures of biological proteins from just knowing the sequence of amino acids of which it is made. It is a computational problem that thousands of researchers around the world have been trying to solve for decades. There are millions of different proteins doing all the work in living cells, but simply knowing what their constituent chemicals are is not enough to understand how they are shaped, and therefore how they work. Scientists are optimistic that solving the problem will herald a new era in medicine, agriculture and even sustainable recycling. Prof John Moult, founding chair of CASP - the international body that monitors progress in the field, tells of the remarkable breakthrough being discussed this week.Whilst China is trying to bring back samples of the moon this week, a much longer-lived space mission to an asteroid hopes this weekend to return samples of the earliest bits of the solar system to earth. Hyabusa 2 will complete a 6 year mission, Japanese scientists hope, this weekend when a small package of asteroid sample drops into the atmosphere above Australia on Sunday morning.And as students across the UK prepare to make their ways home for the holidays, GP Margaret McCartney and Kavita Vedhara of Nottingham University discuss some of the challenges of fast mass covid testing and false negatives.Presented by Alex Lathbridge Produced by Alex Mansfield and Melanie Brown.

Last weekend a joint European-US satellite blasted into space to begin its mission - monitoring the oceans back here on earth. Sentinel 6 Michael Freilich is one of a long line of satellites and has a striking design – appearing like a bright gold farmyard barn with a big pitched roof. Anand Jagatia speaks to Dr Ralph Cordey at Airbus Space and Defence about the latest design iteration and the technology on-board. Oceanographer Professor Penny Holiday from the National Oceanography Centre explains how Sentinel 6’s readings will enhance understanding of sea-level rises and give more detail about the currents in our oceans.We journey back to the cosmic ‘Dark Ages’, a period of time that we know hardly anything about. Dr Emma Chapman is an astrophysicist at Imperial College London who has written a book ‘First Light: Switching on Stars at the Dawn of Time’ to throw light on this illusive chapter in the history of our universe. How close are scientists to finding the first stars?With ambitious new government targets to end the sale of petrol and diesel cars by 2030 how ready are electric cars to fill the gap? One key area many companies are trying to improve are the batteries powering electric vehicles. Peter Bruce, professor of materials science from Oxford University and chief scientist at the Faraday Institution has been working on rechargeable lithium ion energy storage since the 1990s. He speaks with Anand about the current limitations and the most recent developments in battery research and development.Presented by Anand Jagatia Produced by Melanie Brown

COVID Operation Moonshot; Big Compost Experiment; Gulf of Mexico meteorite and new life

Earlier this month, the government rolled out a pilot in Liverpool for ‘Operation Moonshot’, their proposal to spend £100 billion pounds to regularly test the entire UK population for SARS CoV 2. Anand Jagatia speaks to screening expert Dr Angela Raffle and medical test evaluator Professor Jon Deeks from the University of Birmingham. They share their concerns about the scheme and the benefits it may bring.A year ago, BBC Inside Science helped launch the Big Compost Experiment, a citizen science project run by a team at UCL. They asked the public to get involved by providing information about the matter that’s rotting in compost piles around the UK. What do people think about biodegradable plastics and what actually happens to them – do they break down like they are supposed to? Anand finds out about the results so far .from Mark Miodownik, one of the creators of this project, We travel back in time to 66 million years ago, when a massive meteorite smacked into the Gulf of Mexico bringing the reign of the dinosaurs to a cataclysmic conclusion. It was also the beginning of a new chapter in the history of life on Earth. The impact may have caused an apocalypse of earthquakes, tsunamis, volcanic eruptions and the darkness of a nuclear winter; but it may also have created a haven for new life forms to emerge. Roland Pease has been talking to two geologists, David Kring and Tim Bralower, who have found evidence for the return of life in the crater after the carnage of the meteorite strike.Presented by Anand Jagatia Produced by Melanie Brown

mRNA vaccinations; bacterial space miners; Artemis accords

Scientists this week announced hopeful results in two of the big COVID-19 vaccination trials. Trudie Lang, Professor of Global Health at the Nuffield Department of Medicine, Oxford, describes some of the methodology used, what the efficacy statistic means, and how the novel approach of inserting mRNA rather than deactivated virus parts, is so exciting.Prof Charles Cockell has been investigating how bacteria might be grown in space on lumps of asteroid to extract precious minerals, and as Kim McAllister reports, his lab is itself in orbit.And it is just a few weeks since the UK, and several other countries, signed up to a set of bilateral agreements with the US called the Artemis Accords. These are an attempt to update previous outer space treaties on how countries - and indeed companies - might mine and use resources in space, given that no-one can currently legally claim sovereignty. As Dr Thomas Cheney of the Open University and Prof Jill Stuart of the LSE describe, the Accords have been greeted in certain quarters with some discord.Presented by Marnie Chesterton Produced by Alex MansfieldMade in collaboration with The Open University.

COVID in families; earthquake under Aegean Sea; Camilla Pang wins science book prize

We know that children can catch the SarsCov2 virus, even though adverse side effects are incredibly rare. But what isn't clear is how likely they are to transmit the virus? If you’re a parent, are you in danger of catching the virus, maybe brought home from school by your child? A large study, using the anonymised health experiences of around 12 million adults registered with GPs in England, has just been published that explores that question. Dr Laurie Tomlinson, of London School of Hygiene and Tropical Medicine, explains the findings.On October 30th a magnitude 7 earthquake under the Aegean Sea created devastation when it struck Turkish city of Izmir. Marnie discusses the nature of the earthquake and why this area is so seismically active with Dr Laura Gregory, a geologist at Leeds University who has studied the rocks in the region. Professor Tiziana Rossetto, an expert in earthquake engineering at UCL, talks about a recent survey and intervention she carried out with the residents of Izmir to help them prepare for earthquakes.In the last of our interviews with the authors shortlisted for the Royal Society Insight Investment Science Book Prize 2020 Adam Rutherford meets the winner, Dr Camilla Pang. At the age of eight she was diagnosed with autism spectrum disorder. Struggling to understand the world around her, she went in search of a blueprint or a manual that would help her navigate the curious world of human social customs. Nearly two decades on, Camilla has produced one herself, entitled: Explaining Humans: What Science Can Teach Us about Life, Love and Relationships. Presenter: Marnie Chesterton Editor: Deborah Cohen

A new saliva gland, Bill Bryson on the Human Body, and the return of the Dust Bowl

Marnie Chesterton presents an update on the week's science.Behind your eyes, above your mouth but below the brain, two 3cm saliva glands have been hiding since anatomy began. So reports a new study by Matthijs Valstar and Wouter Vogel of The Netherlands Cancer Institute. They describe to Marnie how they found these hitherto unnoticed glands, and importantly how knowledge of these will help people treated for head and neck cancers to get on with their lives in the future. It may be that radiotherapies have been inadvertantly destroying the glands in the past, leading to difficulties eating and breathing. Bill Bryson is the latest in BBC Inside Science's flick through 2020's Royal Society Book Prize shortlisted authors. He talks to Adam Rutherford about his work, The Body: A Guide for Occupants, and his continuing awe at its complexity.And Roland Pease reports on evidence of a return to the Dust Bowl conditions that so devastated agriculture and livelihoods in the US mid-west during the 1930s. This time, we can see the dust storms gathering from space. But that doesn't mean that intensive agriculture, extreme weather and climate change aren't combining to do what might be a re-run of some of the disastrous issues from those years.Presented by Marnie Chesterton Produced by Alex MansfieldProduced in collaboration with The Open University.

COVID reinfections, Susannah Cahalan questions psychiatry and sense of smell and COVID

If you contracted COVID will you then be protected from further infections and illness from SARS-CoV-2 in the future? We’re starting to hear about cases of people being infected by the novel coronavirus for a second time. A handful of these cases have been published in peer reviewed journals. Nottingham University’s Professor of Virology Jonathan Ball discusses how big the problem of reinfection might be. Is it likely to be a common event which could hamper efforts to bring the pandemic under control? In the latest in our series interviewing the shortlisted authors from this year’s Royal Society Insight Investment Science Book Prize, Susannah Cahalan talks to Adam Rutherford about her investigative journalism into the scientific mystery that is mental illness. Her book ‘The Great Pretender - The Undercover Mission that Changed our Understanding of Madness’ focuses on a fundamental experiment carried out in the 1970s by renowned Stanford University Professor of Psychology David Rosenhan. His famous study was published in Science under the title ‘Being Sane in Insane Places’ and describes using ‘pseudo-patients’ to test whether they would be spotted presenting at psychiatric institutions in the US. They weren’t! His findings proceeded to shape modern psychology and psychiatry. It has been a study that Susannah, has come to find rather mysterious, with elaborate descriptions that don’t always seem to add up. Mental illness and applied neuroscience remain tricky disciplines to navigate, but Susannah has had personal experience with her own misdiagnosis of schizophrenia when she has an autoimmune brain disease.COVID does funny things to your sense of smell: Adam got a heightened sense of smell, producer Fi totally lost her sense of smell, and Inside Science reporter, Geoff Marsh – well… his sense of smell just got weird. To find out why, Geoff called in Professors Mathew Cobb, an expert on smell at the University of Manchester, and Tim Spector from Kings College London whose symptom tracker app was instrumental in getting changes to sense of smell on the symptom list for COVID.Presenter – Adam RutherfordProducers– Fiona Roberts and Andrew Luck-BakerProduced in collaboration with the Open University

Test and trace - how the UK compares to the rest of the world; Linda Scott's book The Double X Economy

From the very start of the COVID pandemic, test and trace has been the mantra. But here in the UK it was started, then abandoned as the number of cases rose too high to manage. It’s now been reintroduced and we’re all being encouraged to download the ‘NHS COVID-19’ phone app which can detect whether you’ve been near an infected person using Bluetooth technology. How have other countries around the world been managing to find, test, trace, isolate and support (FTTIS) their COVID patients? And what lessons can we learn from them? Professor Michael Hopkins at the Science Policy Research Unit (SPRU), University of Sussex Business School is part of an international team of experts in science policy, social science, medicine, epidemiology and global health that has analysed and compared national testing systems in 6 countries: Spain, South Korea, South Africa, Ireland, Germany and us, in June, July and August. Michael Hopkins told Marnie Chesterton that we all have something to learn.Over the last few weeks, we’ve been stealing a glimpse into this year’s shortlisted contenders for the annual Royal Society’s Insight Investment Science Book Prize. Linda Scott is an Emeritus Professor from the University of Oxford and a consultant to the World Bank Group on gender economics. Her book, The ‘Double X Economy - The Epic Potential of Empowering Women ’ analyses the economics of gender inequality and the hidden economics which is foundational to the more recognised and acknowledged global economics, that is, the work - much of it unpaid - done by women.

Claudia Hammond looks at the neuroscience behind our sense of touch. Why does a gentle touch from a loved one make us feel good? This is a question that neuroscientists have been exploring since the late 1990's, following the discovery of a special class of nerve fibres in the skin. There seems to be a neurological system dedicated to sensing and processing the gentle stroking you might receive from a parent or lover or friend, or that a monkey might receive from another grooming it. Claudia talks to neuroscientists Victoria Abraira, Rebecca Bohme, Katerina Fotopoulou and Francis McGlone who all investigate our sense of emotional touch, and she hears from Ian Waterman who lost his sense of touch at the age of eighteen.

Brian May's Cosmic Clouds 3-D; How fish move between waterbodies and Jim Al-Khalili's take on physics

There are few images as awe-inspiring as those of the deep cosmos. Photos of the stars, galaxies, constellations and cosmic nebulae are difficult to improve on, but a new book might have done just that, by making them stereoscopic. David Eicher, Editor-in-Chief of Astronomy Magazine teamed up with astro-photographer J. P. Metsavainio, all engineered by astrophysicist and stereoscope enthusiast Dr Brian May, and they’ve created the first ever book on nebulae in 3-D, It’s called ‘Cosmic Clouds 3-D’, and is published by The London Stereoscopic Company.Have you ever thought about how fish arrive in a new pond or lake? Birds fly, other animals walk, or crawl, but fish are somewhat restricted to watery routes, and new lakes don’t necessarily have watery routes that fish can swim down. This question has been puzzling biologists for centuries. Andy Green, professor at the Doñana Biological Station in Spain has finally come up with the answer – a small number of fish eggs can survive in the guts of birds such as ducks.The Royal Society’s Insight Investment Science Book Prize shortlist was announced last week. And as every year, Inside Science is previewing each of the books, and talking to the six authors in line for this most prestigious literary prize.

Royal Society Science Book Prize - Gaia Vince; Biodiversity loss and Science Museum mystery object

The Royal Society’s Insight Investment Science Book Prize’s shortlist has just been announced. Over the next few weeks, Marnie and Adam will be chatting to the six authors in line for the prestigious prize. They’ll be getting a guided tour of ‘The Body – a Guide for Occupants’ with Bill Bryson; Discussing ‘Life According to Physics’ with Jim Al Khalili; Explaining Humans: Discovering ‘What Science Can Teach Us about Life, Love and Relationships’ with Camilla Pang; Linda Scott will be exploring ‘The Epic Potential of Empowering Women’ in her book ‘The Double X Economy’ and Susannah Cahalan will grapple with the definition of mental illness and what counts as insanity in ‘The Great Pretender: The Undercover Mission That Changed Our Understanding of Madness’. This week Gaia Vince discusses her shortlisted book Transcendence - How Humans Evolved through Fire, Language, Beauty, and Time.Last week the non-COVID news was all about how we’d failed yet again to halt the rate of biodiversity loss. The 2020 Living Planet Report showed that across the globe, the populations of mammals, birds, fish, amphibians and reptiles have declined on average by 68% since 1970. These declines, and the less well-documented loss of abundance of many plants and invertebrates, mean that our ecosystems are less diverse, less resilient and less able to provide the ecosystem services that we rely upon. Add to this that The Convention on Biological Diversity’s Fifth Global Biodiversity Outlook reports that we have failed to meet in full any of the 20 ‘Aichi Targets’ adopted by the world’s governments a decade ago. We haven’t reduced the loss of biodiversity, addressed the pressures, adequately tackled the underlying drivers or effectively facilitated the enabling conditions. We are not currently on track to meet the Convention on Biological Diversity (CBD)’s Vision of a world living in harmony with nature by 2050. If all this is making you feel depressed and despondent, be reassured that it's is not all doom and gloom, as there are still plenty of reasons for hope and optimism, according to Dr. Stuart Butchart, chief scientist at Birdlife International.The Science Museum group look after over 7.3 million items. As with most museums, the collection you see on display when you visit is only the tip of the iceberg of the entire collection. Up until now, many of the remainder (300,000 objects) has been stored in Blythe House in London. But now the collection is being moved to a purpose-built warehouse in Wiltshire. The move is a perfect opportunity for curators to see what’s there, re-catalogue long hidden gems and to conserve and care for their treasures. But during the process they have discovered a number of unidentified items that have been mislabelled or not catalogued properly in the past and some of them are just so mysterious, or esoteric, that the Science Museum needs the aid of the public to help identify them, and their uses.

COVID-19 in Winter, Acoustics of Stonehenge and Dog years

As it starts to get colder and we crank up the central heating in our homes, what will the effect be on the SARs-CoV-2 virus? As a respiratory virus like the common cold and influenza, will the coronavirus have a distinct season and will the incidence of COVID get worse in the winter? A pre-print study of over 7000 hospitalised patients across Europe and China during the early days of the pandemic plotted severity of the disease with outside temperature. In European countries as we came out of winter, into spring and then summer, Professor Gordan Lauc, lead researcher on the study, found that the severity decreased as it got warmer outside. He took outside temperature as a proxy for indoor humidity (as it gets colder, we turn on our heating, stay indoors more and the humidity in our homes, and especially our bedrooms drops). He explains to Marnie Chesterton that the subsequent drying out of our mucosal membranes in our noses and throats could be the reason we might expect things to get worse over the winter. We learn a lot about what our ancestors got up to by visualising a scene. Take Stonehenge for example, years of detective work has ascertained that 4,000 years ago, Stonehenge was made up of an outer circle of 30 standing stones called ‘sarsens’, which surrounded five huge stone arches in a horseshoe shape. There were also two circles made of smaller ‘bluestones’ – one inside the outer circle and one inside the horseshoe. But what did it sound like if you were in the middle of all these stones in prehistoric times? Last year, acoustic engineer at the University of Salford, Trevor Cox, and his team built and measured a 1:12 acoustic scale model of Stonehenge to find out. They've now completed the full analysis of those first measurements and Trevor caught up with Adam Rutherford to find out whether knowing the acoustics of a monument can tell us anything about how it might have been used. If you own a dog and like to calculate the equivalent human age of your pup, you might think that every year of your dog’s age equals 7 years in humans. So a one year old hound is 7 years old. Not so! As Geoff Marsh investigates - it’s much more complicated than that. Of course it is! Presenter – Marnie Chesterton Producer – Fiona Roberts

Coronavirus: The types of vaccine; How the UK is scaling up vaccine production

Vaccination has eradicated smallpox, a disease that decimated populations through the 20th century. Polio is almost gone too, and measles is no longer the pervasive childhood threat it once was. It’s clear that vaccination is our best tool to halt the threat of SARS CoV 2, and allow the return to a less restricted way of life. But it takes time to develop and test vaccines although the technologies used to create them have moved on significantly over the last few decades.Professor Jonathan Ball, a virologist at Nottingham University, talks Adam Rutherford through the several types of vaccine that are being explored in the effort to stop the coronavirus pandemic, and how they work. These include live attenuated virus vaccines that are genetically modified to appear to be SARS CoV 2 to the immune system, and RNA subunit vaccines that trick the body into recognising the virus. He discusses the way different vaccines work against disease, and how they trigger different types of immune response. Before a vaccine is approved for general use it has to pass through three trial phases, and Jonathan discusses the vaccines that are already going through phase 2 and 3 in the UK. If and when a vaccine gets approved, it needs to be produced to exacting standards and in quantities great enough to immunise the whole population. The UK Vaccine Manufacturing Taskforce was set up in May to coordinate the effort to make a vaccine. Steve Bagshaw, part of the Taskforce, explains that some vaccines have already been produced around the UK, prior to clinical approval in an effort to ensure that any approved vaccine is ready to be distributed as fast as possible to those at risk. This is unprecedented, and means the pathway to vaccine distribution could be faster than any that have gone before. Presented by Adam Rutherford Produced by Fiona Roberts and Rory Galloway

Bird and dinosaur skull evolution; the wonders of yeast and Science Museum mystery object

Skulls give researchers a great deal of insight into how an animal might have evolved, and skulls can be sensibly compared between species and groups of animals. The 10,000 species of bird around the world are what’s left of an even more diverse group, the dinosaurs. But research on their skulls has revealed that despite the birds’ exceptional diversity, they evolve far more slowly than their dinosaur relatives ever did. This is one of the findings of a huge skull mapping project at the Natural History Museum led by Anjali Goswami. Marnie Chesterton delights Adam Rutherford with what she has recently learned about the single-celled fungus that is yeast. She recently visited the National Collection of Yeast Cultures in Norwich, which stores hundreds of thousands of strains of yeast. She discovered that yeast is not only responsible for the production and subtle flavours of bread, yeast and chocolate, but also that some species of yeast can actually clean carbon dioxide from the air and can be used to feed livestock.The Science Museum Group looks after over 7.3 million items.

What does the science say about the COVID risks of schools reopening? Dolphin ear autopsy

Over the next couple of weeks almost all children in the UK will be back to school. But the pandemic hasn’t ended, and we are far from having a complete understanding of how this virus works, including how it is transmitted and how it affects younger people. Pretty much everyone is in agreement that kids need to be back at school, as the costs of not being physically in classrooms are great - for the education of kids, for their mental health, and for the finances of parents needing to work. But what does the science say about the risks for schools reopening? Will we see a rise in infections in younger people, and hot-spots for the wider community? Adam Rutherford discusses these issues with Paul Hunter, Professor of Medicine at Norwich Medical School, and he finds out from Professor Tim Spector if his Kings College COVID symptom tracker app can shed any more light on whether children display the same COVID symptoms as adults, or could we be missing infections in the young?Marnie Chesterton eavesdrops on an aquatic autopsy.

Smart bricks, The Royal Academy of Engineering awards for pandemic engineering solutions and detecting SARS-Cov-2 in sewage

Red clay bricks are among the most ubiquitous building materials worldwide. Julio D'Arcy, a chemist at Washington University in St. Louis, Missouri, describes to Adam Rutherford how he and his team have turned ordinary house bricks into energy storage units that can power home electronic devices – thanks to the red iron oxide (rust) pigment and a conductive plastic nano-material infused into the bricks These new ‘smart bricks’ can be charged to hold electricity a bit like a battery.As the pandemic continues, we continue to try to find ways to manage it, treat the disease, detect it and cure it. As necessity is the mother of invention, we're currently witnessing some of the most intense periods of scientific innovation in the 21st century. And there have been some incredible discoveries, innovations and inventions in just the last 6 months. The Royal Academy of Engineering announced a special round of awards this week, to recognise the heroics of engineers, designers and scientists to help tackle this pandemic. Professor Raffaella Oconé is Chair of the Awards Committee at the Royal Academy of Engineering, and she told Adam about the range of much needed inventions to tackle COVID19. The current mantra of 'test, track and trace has so far had limited success in the UK. In part because of the difficulty of testing enough people, tracking their movements and tracing the spread of the virus. By the time someone is displaying symptoms and then being one of the few people to then get a test, they may have spread the virus to many people. But scientists across the UK and abroad are beginning to realise that maybe there might be a cheaper alternative, that gives even earlier warning of a spike in infection - by detecting the virus in sewage.Presenter: Adam Rutherford Producers: Fiona Roberts and Beth Eastwood

Land use and zoonoses, California's earthquake risk and the Tuatara genome

COVID19 is a chilling reminder of how pathogens from animals can jump into humans. But it’s not the first time. SARS, Ebola, West Nile virus and bubonic plague are all serious infectious diseases that sat in a host species before crossing to us. But what causes this to happen? Individual case studies suggest that we are partly to blame in the way we use the land, either through urbanisation or agriculture. But how widespread is this, and do our global patterns of land use systematically put us at risk? Adam talks to environmental biologist David Redding from the Zoological Society of London, and his team, whose new study suggests they do.Jessica Bradford, the Keeper of Collection Engagement at the Science Museum, asks for your help with another mystery object that they’ve uncovered during their recent collection move.

How sperm swim, the theory of soil & the Big Compost Experiment update

Adam reveals new research which overturns received wisdom about how sperm swim. More than three centuries after Antonie van Leeuwenhoek peered down his early microscope to observe human sperm or ‘animalcules’ swimming with a ‘snakelike movement, like eels in water’, high-tech observations now reveal that this was, in fact, an optical illusion.Hermes Gadelha from Bristol University used 3D microscopy, a high-speed camera and mathematics, to reconstruct the true movement of the sperm tail. Much to his amazement, sperm have a highly sophisticated way of rolling as they swim. They do this to counter the numerous irregularities in their morphology which would otherwise send them swimming in circles. In doing so, they are able to propel themselves forwards. This highly complex set of movements, seen in 3D, is obscured in 2D when sperm appear to use a symmetrical eel-like motion to swim.Also on the programme, Adam gets an update from Mark Miodownik on the Big Compost Experiment, the citizen science project that wants to know what you compost, how you do it and, most importantly, how quickly the stuff breaks down. Mark reveals how confused participants are, about what they can compost, and explains why items marked ‘compostable’ or biodegradable’ won’t compost at home. Staying with soil, healthy soil is being lost at an alarming rate due to intensive agricultural practices. In England and Wales, a recent survey found that nearly forty percent of arable soils were degraded. Inside Science reporter Madeleine Findlay visits Andrew Neil from Rothamsted Research who has devised a new way of thinking about soil. They’ve solved the mystery of why adding carbon through organic material, like compost, improves soil health. PRODUCERS: Beth Eastwood & Fiona Roberts

She is perhaps most famous for her work using X-ray crystallography which helped lead to the discovery of the double helix structure of DNA, a contribution for which she was not credited at the time. But there’s so much more to the scientific story of her life than just being the wronged woman in the DNA story, who died tragically young at the age of just 37. She pioneered work in the coal industry and on the structure of viruses, including the polio virus. And Franklin’s work has resonance today, in this era of COVID-19.

Pre-prints over peer review during the COVID pandemic and roads and birds

A pre-print is a way for scientists to get their work out quickly for other scientists to comment on and debate. But pre-prints are not peer reviewed; they have not undergone the scrutiny of reviewers and journal editors. They're generally seen as a good thing, but are just a step on the way for science to be verified and published. But it's important to note that the science can be wrong or sloppy in pre-prints, so they have never really been part of the process by which science is disseminated to the general public. That is, until the COVID pandemic. The speed at which the science can be shared has led to pre-prints becoming more and more scrutinised by journalists and used to inform the public about this terrible disease. Fiona Fox, CEO of the Science Media Centre, which is an independent press office for the scientific community, discusses the potential pitfalls of using pre-prints with Adam Rutherford and with Dr Jonathan Read from Lancaster University, who himself got caught up in a pre-print firestorm at the start of the pandemic.The UK has the 12th highest road density in the world, but very little is known about the impact of roads on our wildlife. Now conservation scientists are starting to look at their effects on our bird populations. They call it ‘road exposure’ because they can’t directly measure the impact of road noise, but the noise pollution aspect is very much to the fore. Cambridge University's Sophia Cook has found that roads have a mostly negative effect on most birds in Great Britain. And with that negative effect being stronger in rarer birds this could be adding to the 'simplification' of bird populations and a reduction in biodiversity.Presenter - Adam Rutherford Producers - Fiona Roberts and Beth Eastwood#bbcinsidescience

Science Fraud & Bias, Immunity to COVID-19

Science is all about self-reflection. Scientists constantly check themselves, share their work, and check each other’s data. But how robust is the science upon which civilisation is built, the science which has mapped genomes, cured diseases, split atoms and sent people to the moon? Adam talks to Stuart Ritchie, a psychologist from Kings College London, about his new book Science Fictions which explores everything from biases and human fallibility, to outright fraud. He also talks to microbiologist turned image sleuth, Elisabeth Bik, whose work is revealing that manipulated images appear in scientific papers shockingly often.Now we are several months into the COVID pandemic, scientists are beginning to share their first insights into whether people retain immunity to SARS-CoV-2 after they've had the disease COVID-19. At Kings College London, Senior Lecturer in Infectious Diseases, Katie Doores and her team tracked the antibody levels over the first months after infection with COVID-19. Their first preprint findings suggest a worrying pattern – antibodies against the virus begin to wane within months of being infected. However it is too early to say if and when a person who’s had COVID-19 could be vulnerable to reinfection. Early findings from Marcus Buggert, at the Karolinska Institute in Sweden, suggest that another part of the immune system, the memory T-cells, are active in those who have had the disease, even if they lack antibodies against the virus.Producers: Beth Eastwood & Fiona Roberts

Satellite navigation in the UK; the science of the World Wide Web and Neolithic genomics

Is the UK losing its way when it comes to satellite navigation? There's GPS from the US, but other countries and regions, including Russia, China, India and Japan, either have, or are building, satellite navigation systems of their own. The EU has Galileo, but with Brexit, Britain is no longer involved. The Government has announced that it’s just acquired a satellite technology company called OneWeb. It’s primary role is enhanced broadband, but there’s talk of adding in a navigation function to the constellation of satellites. But how feasible will that be? In an era of cyber-crime, misinformation, disinformation, state-sponsored attacks on rival countries’ infrastructure, government-imposed internet shutdowns in places like Eritrea and Kashmir, the World Wide Web is an increasingly dark and troubled place. Making sense of how the internet has changed from the democratic, sharing, open platform it was designed to be, and predicting what’s next, are the web scientists. Professor Dame Wendy Hall, Regius Professor of Computer Science at the University of Southampton, and a co-founder of the whole field of web science, is hosting an online, annual conference this week. The theme this year is 'Making the web human-centric'.Communal burial sites tend to suggest an egalitarian society, where everyone is considered equal. And this is what we expected the Neolithic societies that spread across Europe with the birth of agriculture around 6000 years ago would be. But DNA evidence from a single human, NG10, buried in 3200 B.C.E in the vast tomb of Newgrange, 25 miles north of Dublin, in Ireland, shows very strong inbreeding. Couple this with the fact the body was buried and not cremated and placed in a highly adorned chamber. Does this indicate an elite ruling class where marrying one’s close kin was the order of the day? Dr. Lara Cassidy, palaeogeneticist at Trinity College Dublin, decoded NG10’s DNA and she tells Adam Rutherford the story. Presenter - Gareth Mitchell Producers - Fiona Roberts and Beth Eastwood

Preventing pandemics, invading alien species, blood types & COVID-19.

As we’re beginning to understand more about SARS-CoV-2, the virus that causes COVID-19, we’re hopefully starting to get some clues on how to deal with the next viral pandemics, and even look at ways of stopping them from happening. To do this, we have to go back to where the virus jumped from its animal host into humans. Like this current coronavirus, many of the pandemic viruses (SARS, MERS HIV, Ebola…to name a few) are zoonotic diseases. They start in wild animals and evolve to jump to humans (sometimes via another animal species). It’s not the animal’s fault. It’s evolution. But has our tangled, often exploitative relationship with wild animals made it harder to stop future pandemics? A paper just published asks these questions and tries to figure out how to prevent future zoonotic epidemics. Dr. Silviu Petrovan (Researcher in the Department of Zoology in Cambridge) and Associate Professor Alice Hughes (Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences) highlight some of the 161 possible actions we should be taking to protect ourselves from the next pandemic.The current pandemic may have curtailed a lot of holiday plans but we are still more global than ever before. Food is coming to the UK from all over the world. With movement comes the opportunity for unwelcome hitchhikers to tag along. A new study, published in Biological Reviews, by a team of researchers from 13 different countries warns that alien species invasions are on the rise. Professor Tim Blackburn from University College London talks to Marnie about this increasing threat. Also on the programme, inspired by a listener question, Marnie asks whether there's any truth behind the idea that susceptibility to COVID-19 could be linked to blood type. Associate Professor of Venom Pharmacology at Reading University, Dr Sakthivel Vaiyapuri, explains what the science says so far.Producers: Fiona Roberts & Beth Eastwood

The Human Genome Project's 20th Anniversary

Adam Rutherford is back to celebrate the 20th anniversary of one of the most ambitious and revolutionary scientific endeavours of all time - the Human Genome Project. Its scope and scale was breath-taking, set up to read every one of the 3 billion nucleotides, or letters of genetic information, contained within the DNA in every cell of the human body. It took seven years, hundreds of scientists, cost almost $3 billion and, amazingly, came in under budget and on time. Adam reflects back on that momentous time with Ewan Birney, Director of the European Bio-informatics Institute, part of the European Molecular Biology Laboratory. Twenty years ago, he was a PhD student working on the project, in the months leading up to the first draft. The Human Genome Project underpins many branches of science, from human evolution and synthetic biology to forensic genetics and ancestry testing. But a key motivation for the project was to alleviate human suffering. While the ‘cures’, hyped by the media back in 2000, were not realistic our understanding of disease has been revolutionised. Adam talks to Cancer Research UK Scientist, Dr Serena Nik-Zainal, from Cambridge University, who explains why the sequencing of the human genome has been so crucial to the diagnosis and treatment of breast cancer. The Human Genome Project is also playing a crucial role in the COVID-19 pandemic. Dr Kenneth Baillie has been treating critically ill patients at Edinburgh’s Royal Infirmary since the pandemic started. As the Lead on GenOMICC, a global collaboration on genetics and critical illness, he has joined forces with Genomics England and the NHS, to pinpoint genetic signals in these patients to help identify the best treatments.Producers: Beth Eastwood & Fiona Roberts

Coronavirus conspiracy, Listeners' mask questions, Solar Orbiter gets close to the Sun

Throughout the pandemic, we've seen an explosion in information about the science of the virus, SARS-CoV-2, and the disease it causes, COVID-19. An article online, or a text forwarded, could be true and sounds about right, but how do you know that it's accurate? When scrolling through your social feed, how do you decipher fact from fiction? A new report, by Kings College London and Ipsos MORI, reveals that those of us who get our news from social media are more likely to believe misinformation about the pandemic.Marnie talks to Jack Goodman of the Anti-Disinformation Unit at BBC Online, a new team set up to tackle the problem. She finds out how science fact turns to science fiction online, and what the team is doing to try to counter this.Now that wearing face masks are now mandatory in a number of situations, a lot of us are making our own. BBC Inside Science listeners sent in lots of ideas about the design, maintenance and durability of face masks, and other ways to protect against spreading the coronavirus. We asked Professor of Materials & Society at UCL Mark Miodownik in to comment.In February this year, the European Space Agency’s Solar Orbiter, SolO, successfully launched, escaping this planet before most of us went into lock-down. Professor Lucie Green from the Mullard Space Science Lab at University College London, is a solar scientist and part of the team that will be using a telescope to take images of the Sun in extreme ultraviolet light. The orbiter is now in it’s ‘Cruise Phase’ which means most of its instruments have now been tested and calibrated, but aren’t yet up and running. One instrument that has been operational since just after launch is the magnetometer, which will collect data on the Sun’s complex and dynamic magnetic field.Presenter - Marnie Chesterton Producers - Fiona Roberts and Beth Eastwood

Engineering out of lockdown and should we castrate male dogs?

As the UK gradually begins to ease out of lockdown, Marnie explores how engineers are hoping to reduce the spread of Covid-19. We’ve learned how infected people exhale droplets and aerosols, containing the virus, and how we can then either inhale them, or transfer them to our faces by touching contaminated surfaces. Many shops already have screens and physical barriers, while schools and offices are re-configuring desks and walkways. What role does the environment play in our overall risk of becoming infected and what can we do about it? This is the focus of the SAGE Environmental Working Group. Marnie talks to its Chair, Catherine Noakes, Professor of Environmental Engineering for Buildings at Leeds University. Minimising the risks that contaminated surfaces pose is a key challenge that engineers are now trying to address. Marnie asks Birmingham University Research Scientist, Felicity de Cogan, about the surface she created which kills bacteria in seconds. She's now re-purposing the technology to kill the virus that causes Covid-19. If her laboratory studies prove that it kills the virus as quickly, as she hopes, the technology could be used to create antiviral PPE that can be re-used rather than thrown away.Epidemiology has been thrust into the spotlight in recent months, helping us track the viral threat facing all of us. But companion animal epidemiology - which studies disease in pet populations - is a much younger field. It’s one that’s starting to search for the answers to another puppy-related conundrum that’s been puzzling BBC Inside Science reporter Geoff Marsh - should he get puppy Kevin castrated? Neutering has become a cultural norm in the UK. But the health risks to neutered male dogs include cancers and joint disorders in some breeds. The operation and anaesthetic carries some risk as does the age of the dog when the operation is carried out. The risk of dog populations exploding with hundreds of un-neutered dogs is low, because most owners control their dogs to such a degree the chance of unplanned mating doesn't come up. But neutering can help with some behavioural problems in pet dogs. So what is the answer? Will Kevin remain intact?Presenter - Marnie Chesterton Producers - Beth Eastwood and Fiona Roberts

Back to School and Covid-19 and Ordnance Survey and the pandemic

As the lockdown eases and some children, in preschool and primary years, start heading back to school, what impact will this have on the pandemic, how will we know and is there anything we can do about it? Marnie Chesterton talks to Professor of Mathematical Biology at Cambridge University, Julia Gog, who co-chaired the group that advised the government on the impact of easing school closures. She explains why the limited opening of schools provides a golden opportunity to learn about its impact on the pandemic, and inform what happens in September when the new school year begins. Marnie also talks to Tim Spector, Professor of Genetic Epidemiology at King’s College London, to find out what parents can do to help control the spread of the virus in their communities. He runs the COVID Symptom Study, a huge citizen science project that’s pinpointing the symptoms most closely associated with Covid-19. Millions of British adults have downloaded the app, to take part in the study, logging how they feel each day and adding symptoms when they feel unwell. The breakthrough that losing your sense of smell, or anosmia, is a common symptom in Covid-19, arose from this app. While children with Covid-19 tend to have mild or no symptoms, Tim Spector believes that some cases are being missed because many of the symptoms we’re told to look out for in adults, such as fever, are transient or absent in children. Tim explains which symptoms parents should look out for in children, including anosmia and a range of rashes such as ‘covid toe’. If parents log their children’s symptoms each day, the hope is he’ll have enough data to further refine the symptoms most closely associated with Covid-19 in children. Parents will then be better placed to spot them, if they occur, and keep their children at home.You might be forgiven for thinking that Ordnance Survey (OS), the national mapping agency for Great Britain, would be having a quiet time during the lockdown. But its online OS Map apps have seen a 300% increase in use, with users not only checking out new places and walks in their local area, but using the virtual maps to plan and imagine themselves on walks in more remote and far flung parts of Great Britain. But Ordnance Survey is so much more than just leisure maps. It runs the Master Map of Great Britain, a massive, interactive, geospatial database which can be interrogated by anyone in the public sector with questions on geography, planning, logistics, addresses and more. The list is long. And during the coronavirus pandemic, the Mapping for Emergencies service has been busy helping the NHS find places for blood testing facilities and PPE storage; working out which walkways are wide enough to allow social distancing, working out where the nearest pharmacies to vulnerable people are and much more.

Testing & Tracing the coronavirus, and the traces our movements leave behind

Inside Science this week is all about our information - the stuff we volunteer and the traces our everyday movements leave behind.With the launch of NHS Test and Trace across England, if you start to feel unwell with suspected Covid-19 and call a new NHS hotline 119, you’ll be tested for the virus. Your close contacts will be traced and, if you test positive, you'll be asked to self-isolate for 7 days, and your contacts asked to quarantine for 14 days. The route to those close contacts is currently through manual tracing - you have to give the details of everyone with whom you’ve been in close contact. But in the coming weeks, the plan is to integrate the NHSX app, currently being trialled on the Isle of Wight. This will pick up close contacts with people you don't know, on public transport, for example, provided they also have the app. It’s a new way to fight a pandemic, but the pioneers here are the residents of the English town of Haslemere in Surrey who, back in 2017, were tackling a terrifyingly contagious and, thankfully, hypothetical virus spread by ‘patient zero’ Hannah Fry. Created for the BBC4 documentary: Contagion, it was an experiment to see how we could fight the next pandemic. The BBC built an app, which residents downloaded and, crucially, it created a data-set. Evolutionary Biologist Dr Lewis Spurgin, from University of East Anglia, has used this data-set to explore the impact that different control strategies could have on the spread of the virus that causes Covid-19.In a different case of tracking and tracing, involving some policing by members of the public and journalists, Dominic Cummings’ comings and goings have consumed the nation this week. Just how much are our everyday movements being clocked, monitored and recorded? What traces do our phones, cars and even our faces leave behind? And who gets to see this information?

Coronavirus-free science, the impact of lockdown on climate change and the odds of both life and intelligent life existing.

In response to listeners who have expressed coronavirus fatigue in recent weeks, Marnie Chesterton brings us up to date on some of the best and brightest breaking science we might have missed, with BBC’s Non-Covid-19 Science Correspondent Jonathan Amos.Inching back to pandemic news, Marnie investigates the fallout of the lockdown from a climate perspective. In many countries, citizens have been asked to stay at home and not to travel unless it’s strictly necessary. As a result, the hubbub of normal life has slowed to a trickle. What impact has this had on levels of carbon dioxide in the atmosphere? Corinne Le Quéré, the Royal Society Professor of Climate Change Science at the University of East Anglia, explains just how dramatically these emissions have been affected around the world. And the chances that intelligent life exists on other planets. David Kipping, Assistant Professor of Astronomy at Columbia University in the US, has calculated the odds of both life and intelligent life existing if he were to re-run earth’s history.

Coronavirus R number, genome study of Covid-19 survivors and using aircraft messages to assess aviation

R seems to have found its way into the newspapers and on Radio 4 as if it’s a word, or a letter, that we should all be familiar with and understand. As part of the government’s briefing on Sunday, it appeared in a pseudo-equation, the infographic - 'COVID alert level = R + number of infections' - the Government called R the 'Rate of Infection', but it is commonly known as the 'Reproduction Number'. So what exactly is R, and what does it do? Mathematical Biologist, Kit Yates, from the University of Bath, clears up the confusion, and explains how R was first calculated for covid-19. And one of the scientists tracking R in the UK is Petra Klepac, who is Assistant Professor in Infectious Disease Modelling at the London School of Hygiene and Tropical Medicine. She explains how crucial R is in tracking the pandemic and how it’s now being used to shape the way we get out of lockdown.There are so many variables about who will survive Covid-19 and who, unfortunately, will not. Many people will only experience mild symptoms, but a minority will have a severe or even life-threatening response. Whilst some of the difference can be explained by age, or underlying health conditions, the reasons why men and some ethnic minorities and a number of apparently fit younger people become so ill, is one of the great puzzles of this pandemic. Some of the uncertainly is down to environmental effects. But a lot of the variability could be down to our genomes. To try and find out, this week Genomics England announced funding for a study - The GenOMICC - COVID Genomics UK (CoG-UK) Partnership for Severely Ill Patients to sequence the whole genomes of 20,000 severely ill and 15,000 asymptomatic or very mild patients. Led by Genomics England, these genomes will be compared with those held in the 100,000 Genomes Project dataset.The coronavirus pandemic is really highlighting the need for fast, accurate ways to analyse data on a global and national scale. Be that data on the number of people dying or track and trace data from various apps. But do we realise how much data we leave about ourselves online even in normal times? This is something Professors Tobias Preis and Suzy Moat in the Data Science Lab, at the Warwick Business School get very excited about. They use rapid analysis of big data to try and understand our behaviour as a way to rapidly inform economists and policy makers on how the world works. They have been looking at alternative data sources to give us quicker estimates of what’s happening in the world – travel patterns, economic indicators, how many people have a given disease.This is going to become invaluable both during and in the aftermath of the pandemic, when understanding the economic fallout will be key to helping the economy recover. Take their latest work – where they’re gathering much quicker estimates on the contributions of air travel to the UK’s GDP.Presenter – Marnie ChestertonProducers – Fiona Roberts and Beth Eastwood

Should the public wear face masks? Did SARS-Cov-2 escape from a laboratory in Wuhan?

Advice about whether the public should wear face masks, to protect against infection by the coronavirus, differs around the world. In Europe, policy recommendations are mostly geared towards homemade masks. As this country waits to find out how we’ll venture out of lock down, should we be wearing face masks out in public too? The government’s mantra throughout the pandemic has been “follow the science” but on this issue there is ongoing debate, with strongly held and differing views. The Royal Society’s DELVE Initiative (Data Evaluation and Learning for Viral Epidemics) put out a report this week to try to bring some clarity to the issue. Marnie Chesterton asks Professor of Primary Care Health Sciences at Oxford University, Trisha Greenhalgh, and microbiologist and Professor of Environmental Healthcare at the University of Southampton, William Keevil, why there is so little science to inform the policy-makers. If the government recommends that we all wear cloth masks, we'll be wearing them for the common good - they’re better at stopping the wearer from spreading the virus than protecting him or her from catching it. Choosing one that fits, made from the right material, and keeping it clean is also crucial. If you’re not really up to making your own mask, Professor Mark Miadownik at UCL’s Institute of Making warns against the single-use surgical masks, now a common addition to the litter scene and a bane to the environment. As the SARS-CoV-2 virus that causes COVID-19 continues to spread at an alarming rate in the United States, with well over a million confirmed cases and over 70,000 deaths, attention in the White House has been turning to suggestions that the virus originated in the Institute of Virology Laboratory in Wuhan, China and not in the wild where bats are the ultimate suspected source. For years, a group there led by “bat woman” Jungli Shi, have been collecting virus samples and studying them to see if they could infect us humans. This is standard virology, trying to understand where the next pandemic viral threat might come from. But conspiracy theorists have been suggesting that there’s more going on, such as deliberate genetic manipulation of the viruses, weaponising them, or just unsafe management. These ideas have been taken up by President Trump and his team. BBC Inside Science reporter Roland Pease asks the experts what they think. Is there any place for this sort of politics in the pandemic? Presenter - Marnie ChestertonProducers - Fiona Roberts and Beth Eastwood

Testing for immunity to COVID-19 and Citizen science on BBC Radio past and present

This week, the Government’s target to be testing 100,000 a day for COVID-19 looks like it won’t be met. But we’ve heard about many people who experienced the virus mildly, or who’ve tested positive with no symptoms at all. If you really want to know who has had the virus, the only way to tell for certain is with an antibody, or serology, test. Describing how they work is Professor of Virology at Nottingham University, Jonathan Ball. Eleanor Riley, Professor of Immunology and Infectious Disease at Edinburgh University, explains why its so important to get the specificity and sensitivity of these tests right, and reveals what they can and can't tell us about individual and population-wide exposure to the virus. We like citizen science on BBC Inside Science, it’s an opportunity for anyone and everyone to try their hand at some scientific projects, learn about the scientific process and help researchers crunch through masses of data. Professor Chris Lintott co-founded Zooniverse, the biggest citizen science platform over a decade ago. He’s a regular on the programme telling us about the latest Muon-hunting, Penguin-counting, galaxy-searching opportunities they offer. But they’re not the only ones, Butterfly Conservation want you to help them track the timing of butterfly emergence in the UK and are asking people to play their protein folding online game to help them find a possible cure for Covid-19. But back in the 1930’s BBC radio producer Mary Adams was running a series called ‘Science in the Making’, where listeners were invited to participate in, what would now be called ‘citizen science’ experiments. With topics as diverse as charting the timing of blackbird egg laying and deciphering the meaning of dreams, a scientist would explain their hypothesis and ask the audience for help. Allan Jones, a senior lecturer in computing and communications from the Open University has been digging into the BBC’s earliest public science experiments, and the woman who decided to broadcast them.

Understanding Covid-19 death rates; Contact tracing apps; Whale sharks and atomic bombs

Every death is a tragedy for grief-stricken families, but every set of statistics is an opportunity to understand the virus and the disease Covid-19 a bit more. In fact gathering these data, quickly and accurately, is a priority at the moment, up there with developing a vaccine and rolling out widespread testing. Gareth Mitchell discusses, with, David Spiegelhalter, who is the Winton Professor of the Public Understanding of Risk in the Statistical Laboratory at the University of Cambridge, why it’s so hard to measure coronavirus fatalities.The Covid-19 pandemic is unprecedented in modern times. There will no doubt be years of debating over who managed the outbreak the best, which tools and actions were implemented at the right time and in the right way. One small, but important part of dealing with the viral outbreak is contact tracing – discovering who is infected and who they might have come into contact with. This has to be done quickly, so the people an infected person had contact with, can be found and informed to isolate, before they themselves spread the virus further. Some countries used this early on in the pandemic (Singapore and South Korea, have successfully used it to contain their outbreaks, while Germany, which has a far lower case and death rate than the UK, has also worked hard on contact tracing.) Others are hoping to implement contact tracing as a means of easing social distancing or coming out of lockdown. To do this public health agencies will have to start aggressively contact tracing and at a much higher level than they were a few months ago. The UK started using contact tracing then stopped, they are now looking to restart it.A plausible way of doing this is to make use of the fact that a lot of people carry a mobile phone, so apps that can help are being developed and used. There are biological factors that need to be taken into account (reliable, accessible testing in the first place) but also logistical, practical and security issues… who are we giving our data to? And what are they doing with it? Could it be used to restrict my freedom in ways other than just managing the spread of the virus? Timandra Harkness author of Big Data, Does Size Matter? and Fellow of the Royal Statistical Society, and a member of their working group on Data Ethics helps answer these questions.Finally, a small bit of good that’s come out of another dark time in our recent history. Atomic bomb tests during the Cold War. The nuclear fallout, doubled the amount of an isotope called carbon-14 in the atmosphere. And that has turned out to be very useful for scientists working on a crucial conservation effort – to age and safeguard the world’s largest fish - the Whale Shark.Presenter - Gareth Mitchell Producer - Fiona Roberts
