The Inquiry

The life expectancy of Americans has fallen in recent years after a long period when it had been increasing. There are a number of factors which contribute to the fall. The Covid pandemic, with over 1m deaths, made a significant impact on lowering the average life expectancy. In comparison with other peer countries, the USA also did not return to pre-Covid levels at the same rate. However there are also other important factors driving this, namely gun deaths and drug deaths as a result of opioid overdoses. And another major contributor to lower life expectancy in the States is inequality in the US healthcare system. In this edition of The Inquiry Tanya Beckett explores why US life expectancy is falling. She hears from Jeremy Ney an adjunct professor at Presidio Graduate School in San Francisco and author of American Inequality, a data project that highlights US inequality and regional divides. Dr. Mark Rosenberg helped set up the Centre for Disease Control’s National Centre for Injury Prevention and Control (NCIPC) and is a key proponent of research that examines how to reduce gun violence. He explains how gun deaths among young people have a big influence on the average life expectancy numbers. Dr. Judith Feinberg, is a professor at West Virginia University School of Medicine - her experience of working with communities with high levels of opioid problems makes her an authority on the extent to which drug overdose deaths impact average life expectancy. Ellen Marra is a professor of health economics at Harvard University - she says that diseases such as cancer and cardio deaths are big factors in lower life expectancy, compared with the number of gun and opioid deaths.

The Palestinian President Mahmoud Abbas is ageing and his ruling Fatah party is deeply unpopular. There have been protests against him and the Palestinian Authority. Many Palestinians feel the PA has lost legitimacy. There’s no plan for how to choose a successor to Mahmoud Abbas and any candidate is likely to be controversial. There’s a risk that an unpopular replacement may throw the occupied territories into chaos, even violence, and have major implications for the future goals of Palestinian people.

In July 2023 a group of lawmakers in the US held a session to explore evidence of extra-terrestrial life. The evidence included the famous Tic Tac videos of mysterious objects flying through the sky. Pilots described encounters with Unidentified Anomalous Phenomenon – or UAPs. Congress also heard of a secret US government programme that retrieves and reverse engineers materials made by non-humans, including crashed and intact craft – and possibly the remains of the entities that piloted them. So does this mean we are not alone in the universe? Do sightings and hearsay provide enough scientific data to answer a question that has been asked by humans for thousands of years – are we alone in the universe?

Working from home became the norm for millions of us around the globe during the Covid-19 pandemic, but now three years on some major employers are insisting on their employees returning to the office, for at least some part of the working week. The levels of working from home currently vary, depending on the country and its culture. The Netherlands are looking at legislation to allow employees the ability to work remotely, whilst in Japanese culture the preference for employees tends to be going into the office. So how do we navigate a future where both business and personnel needs are met to provide a good work life balance.

About 60 percent of the Amazon rainforest is in Brazil and it is home to more than 300 indigenous groups. But for centuries both the rainforest and its indigenous inhabitants have been under threat, from deforestation, agri-business, mining and politics. Brazil’s current president, Luis Ignácio de Silva, has made the future security of the Amazon and its peoples a key policy pledge. So far, the president has appointed a new minister for indigenous peoples and according to government figures, the first six months of this year saw a 33 percent drop in deforestation. But at the recent Amazon Summit in Belém, the president failed to commit to zero-deforestation, to the disappointment of indigenous leaders. They are calling for more protection for their land and their way of life, which they say is crucial to the future preservation of the Amazon and a matter for the whole world. This week on The Inquiry we are asking ‘Can Brazil’s indigenous population save the Amazon?’ Contributors: Pedro Cesarino, Professor of Anthropology at the University of Sao Paolo and Writer, Brazil Carlos Peres, Professor of Conservation Biology at the University of East Anglia, England Ana Carolina Alfinito, Legal Advisor at the NGO Amazon Watch Kawá Huni Kuin, Indigenous leader and representative from the Huni Kuin/Kaxinawá people, in the State of Acre, Brazil.

Environmental activists in the UK have disrupted high profile sporting events in an effort to persuade the government to stop oil development. How would stopping oil production impact those countries around the world with economies dependent on oil? Tanya Beckett explores the history of oil, the implications of the Ukraine war for its price, how countries like Nigeria and Norway are dependent on oil revenues, and the challenges facing new oil producers in the global south as they face international efforts to limit new oil development in order to meet international climate targets.

South Africa once had the most abundant and cheap electricity on the continent. Now, it is experiencing power blackouts. It’s called loadshedding, the process by which the power company Eskom occasionally reduces the demand for electricity on the national grid. For many South Africans this means no electricity for up to ten hours a day, almost every day. The result is disruption to everyday life, impacting on work, education, sanitation, food and heating. In 1994 Nelson Mandela’s African National Congress party promised a better life for all South Africans. So why is South Africa’s infrastructure crumbling?

In June 2023 the British government announced a £40 million pound pilot scheme to increase access to specialist weight management services in England -It reads “Using the latest drugs to support people to lose weight will be a game-changer.” The scheme will use prescription drugs like Wegovy and Ozempic, a once weekly injection that slows down the emptying of the stomach and suppresses the hunger hormone in our brains. Both these medications are made of the same of the same drug called Semaglutide. Semaglutide mimics the hormone released by the body when we eat food, helping people feel fuller for longer and suppressing mental chatter about various food cravings. When prescribed alongside diet, physical exercise and behavioural support, the drug can help obese people lose 15% of their body weight. Ozempic has been used to treat sufferers of type 2 diabetes since 2018 when doctors noticed that alongside increasing insulin the drug helped people lose weight. In 2021 the drug was approved as a fat loss injection under the name Wegovy. Since then, stories of the 'fat loss wonder drug' have lit up social media, rumours are rife about who might be using it in Hollywood and international demand has skyrocketed. But it's not meant for shedding a few pounds to fit into your favourite frock. So this week were asking are weight loss drugs the answer to obesity?

Venezuela is the country with the largest oil deposits, yet 3 in every 4 Venezuelan lives in extreme poverty. More than 7 million people are recorded as having left the country since 2015 in search of a better life, causing the largest ever displacement of people in Latin American history. And it’s only surpassed in numbers by those people leaving Ukraine. But Venezuela is not at war, its current humanitarian crisis is the result of years of political and economic turbulence. International sanctions, imposed on the country with the aim of pressing the government to change its policies and restore democracy have had little impact, other than making it more difficult for Venezuela’s economy to function. Presidential elections are due to be held in the country next year, but talks between the government and the opposition to ensure that they are free and fair are currently at a standstill.

Canada is in the grip of the worst wildfires in recorded history. Blazes are devouring millions of acres of forest, forcing more than a hundred thousand people from their homes. Toxic smoke has blanketed cities across North America. Why are wildfires getting more frequent and intense across the world? Part of the reason is climate change, but part of it is also population growth and land management. The question is, what should we do about it? How can we stop wildfires?

Following the Wagner mutiny in Russia, and with fighting intensifying as Ukraine presses on with its counter-offensive, there’s concern about increasing instability around potential use of nuclear weapons. President Putin has threatened to use tactical nuclear weapons in Ukraine. Gary O’Donoghue asks how likely this is, and if the nuclear threat level is rising across the world. Are countries around the world looking at what is happening in Ukraine and adjusting their nuclear thinking? As China seeks to increase its own nuclear arsenal, experts are talking increasingly of Tripolar nuclear competition, taking in Russia and the US. In this uncertain world, what role - if any - is there for nuclear non-proliferation treaties and how can the nuclear threat be contained ?

The medieval city of Venice is situated in the heart of a lagoon on the coast of northeast Italy. It was built on a large area of low-lying marshland. A system of wooden poles driven into the soft mud created an underwater forest. It still forms the foundations of the city we see today. For centuries the City has had to battle with ‘aqua alta’ or high tides from the Adriatic sea. And the gradual combination of water erosion and rising sea levels means the City is now facing a more urgent battle to stay afloat. In recent years a series of barriers which sit on the sea floor and which are raised when an ‘aqua alta’ is expected have been successful in keeping the majority of the city dry. But its already been acknowledged that the Mose Barrier, as it’s known, is not a permanent solution for the future. An idea designed to complement the Mose Barrier, one which was suggested more than a decade ago, is to inject seawater into wells underneath the city. The scientists behind the project are confident that if it were to be adopted, it would provide a uniform uplift to the city without causing any structural issues to the buildings. This week on the Inquiry we’re asking ‘Can seawater save Venice from flooding?’ Contributors: Prof Claire Judde de Lariviere, Medieval Historian, University of Toulouse Hermes Redi, Director General of the Consorzio Venezia Nuova (responsible for the Mose Barrier) Professor Pietro Teatini, University of Padua, Chair of UNESCO International Initiative on Land Subsidence Prof Carlo Ratti, MIT, Co-Chair at the World Economic Forum’s Global Future Council on Cities.

Thailand’s recent elections produced a shock result. A popular progressive party called Move Forward won the most seats. But the leader of the government has not yet been named as the country moves through its procedures for verifying the election results. If the head of the party, Pita Limjaroenrat, is successful, it will mean civilian rule for the first time in over a decade. But the path to that role is far from smooth. There are many challenges as military coups and court rulings have cut many previous political careers short.

In 2009 Disney bought Marvel studios and helped transform the company into a movie making powerhouse that brought a new world of superhero stories to the silver screen, called The Marvel Cinematic Universe. Since then the franchise has generated over $30 billion dollars in profit, released 32 films and has even made its way onto the small screen… And it’s not slowing down any time soon. Before the end of next year we can expect Captain America, Thunderbolts, The Marvels and Blade in cinema’s and Daredevil, Agatha: Coven of Chaos and Iron heart streaming on Disney Plus. But glitchy graphics in recent projects like, ‘She-Hulk’ and patchy plots in ‘Ant-Man and the Wasp Quantomania’ have left fans and film critics wondering if marvels conveyor belt of content has led to it losing its magic.

A fifteen minute test flight of a plane fuelled only by hydrogen was successfully completed over recent months. Trucks are already running on the fuel in the US, as are trains in Canada and the UK. Both Toyota and Hyundai have expressed a desire to explore the gas as an option for their smaller vehicles. The UK has announced plans to use hydrogen as a replacement for natural gas in two trial villages, Whitby and Redcar, having already completed tests at Keele University. Several glass and tiling companies are also testing the potential energy source. There is a lot of buzz around the idea of replacing our current fossil fuel usage with hydrogen, and for good reason too. Hydrogen is everywhere and it can be made via green methods and its only by-product is water. It almost sounds almost too good to be true, and perhaps it is. That’s why this week we ask, will hydrogen solve our energy needs? Presenter: David Baker Producer: Christopher Blake Editor: Tara McDermott

Ron DeSantis, the governor of the US State of Florida has now declared his republican nomination for the 2024 Presidential Election. He’s the latest in a line of republican contenders keen to take on President Joe Biden for the White House. Since his appointment as Florida’s governor in 2018, Ron DeSantis has been busy stamping his own brand of cultural conservatism on the ‘Sunshine State’, including limits on abortions and restricting sex and gender identity education in schools. The latter, known officially as the Parental Rights In Education Act’, denounced by critics as ‘Don’t Say Gay’, has led to an ongoing legal battle with Disney over their criticism of the Act. Ron DeSantis claims that his ‘Florida Blueprint’ can act as a guide for Federal Policies. But before that, he’s got an uphill battle to unseat his former political mentor Donald Trump. The former President is currently leading the Republican field in the polls and he’s not wasted any time in attacking Ron DeSantis on a number of fronts, from insults and nicknames, to criticising some of his policies.

Official figures report that there are more than eight million houses standing empty across Japan, the reality could be even higher. One of the highest concentrations of empty houses or ‘Akiya’ as they are known, is in the Prefecture of Akita, in Northern Japan, where in the past five years, houses have been abandoned at a rate of 13.6 percent. The problem is being put down to a number of factors. The lack of employment or education opportunities in rural economies means more migration into the cities. An ageing population combined with a low birth rate is upending traditional living arrangements. The land on which property sits benefits from tax relief, and if a property disappears so does the preferential measure. Building codes are strict. Religious reasons are cited as another factor - it’s believed that the spirits of ancestors still dwell in the home. The Government has invested heavily in the housing sector, from financial incentives to occupy older empty houses, to focusing on building preferred new and expensive homes in Japan’s cities in order to boost the economy. But as the population demographics continue to shift and shrink, unless the balance of supply and demand is addressed soon, then the suggestion is that empty Akiya will be an ongoing issue for Japan. This week on the Inquiry we’re asking: Why are there millions of empty houses in Japan?

The Great Green Wall is one of the most ambitious environmental projects ever conceived, creating a vast belt of vegetation spanning Africa by 2030; from Senegal on the Atlantic to Djibouti on the Red Sea. It was heralded as Africa’s contribution to the fight against climate change, reversing damage caused by drought, overgrazing and poor farming techniques. The regreening of 11 Sahel countries on the edge of the Sahara Desert would create millions of jobs, boost food security, and reduce conflict and migration. The plan was launched by the African Union in 2007, and despite political consensus, only 4% of the Great Green Wall had been completed by 2021. So what has gone wrong? What lessons have been learned, and will a change of strategy ensure its success by the end of the decade?

For the first time in his 20 years in power Erdogan is facing serious pressure - and the choice voters make in this month’s presidential election could define Turkey’s destiny for decades. The impact of February’s devastating earthquake in Turkey is one of the key factors determining how voters will decide on their next president. The Turkish economy is also under pressure with inflation running at 55%. Against that background, a coalition of opposition parties, The Table of Six, are supporting a single candidate, Kemal Kilicdaroglu, against President Erdogan. As polls predict a tight result in the first round of the election, The Inquiry asks: What does this presidential election mean for Turkey’s future?

Last November Israel elected its most far right government in its 75 year history. Months of protests followed over its plans for reform of the judicial system. Benjamin Netanyahu’s new coalition government is proposing an agenda that goes beyond domestic reforms – and not everyone is happy. As well as domestic protests, some of Israel’s allies are nervous as, with the government’s attention taken up by internal challenges, new alliances are forming in the middle east. This episode of The Inquiry explores the reasons behind the tension and protests in the country and asks, why is Israel in turmoil?

Next year Americans will go to the polls to choose their next president. For many, the race has already begun. Digital electioneering in US elections has been steadily developing over the last 15 years, but this time around, advancements in artificial intelligence could be a game changer. There have been huge strides in generative AI in the past year. One of the most accessible AI tools now available to the general public is the software known as ChatGPT, which can scour the internet for information, producing text for speeches and essays. Generative AI is widely used to produce social content around image and text, but what will happen when full on AI video becomes more readily available to any user? AI systems will be able to reach voters with messages targeted specifically to them, but will they be able to trust them? There are concerns that voters will have an increasingly tough task working out which campaign messages are genuine and which are not. To date, there is currently little regulation of a system which has already been used to create deep-fake manipulations of people and what they say, provoking questions over authenticity. So do we all have to be more aware of how much we allow AI to shape our democracies? This week on the Inquiry, we’re asking: Will AI decide America’s next president?

Recent protests in France oppose plans to raise the retirement age from 62 to 64. The demonstrations stem from a government plan so people would work -and pay into the pension system - for longer. There’s also concern about what that change might mean for those who are many decades away from pension age. France isn’t the only country facing economic efficiency challenges as populations age and leave the labour market. As more people leave Europe’s labour market, will young workers have to pay for the old? The Inquiry hears also about the productivity challenges facing Spain and Germany.

Recent cloud storage outages have exposed just how the modern world is reliant on remote servers to hold data that runs everything from websites, to digital operating systems and businesses. When cloud storage emerged, it meant that information could be streamed, rather than held in a device’s memory. Vast data centres were built where land was cheap and their owners soon realised that they could sell excess memory space on their servers. They became so-called “hyperscalers” providing cloud services. They include Amazon Web Services, Google and Microsoft, and the business is worth $500 billion a year. But there are concerns that too much information is already in the cloud. Critical data – such as aircraft control and military systems is being uploaded to publicly accessible servers. If there’s a glitch, the consequences could be catastrophic. Remote cloud systems therefore need to run 24 hours a day without fail, but the power the industry uses causes around 2 to 3% of all global carbon emissions. It’s set to get even bigger, but at what cost to the environment? This week on the Inquiry, we’re asking: will we ever run out of cloud storage?

Saudi Arabia has entered into a new era of relations with its long time rival, Iran. It’s a deal that has the potential to be very significant for the Middle East region. It’s part of a vision of a new Saudi Arabia spearheaded by its Crown Prince, Mohammed bin Salman. It’s a vision of futuristic cities, a new society, and a move away from an economy reliant on oil, not to mention new deals with ancient rivals in the region. How much of this new vision of Saudi Arabia is achievable and is the man at the centre convincing enough to make it work? This week on The Inquiry we’re asking, what is Mohammed bin Salman’s vision for Saudi Arabia?

In 1981, the rock photographer Lynn Goldsmith did a photoshoot with an up-and-coming singer songwriter called Prince. A few years later, he became a superstar, and she licenced one of her photos to Vanity Fair to be used as a reference picture for an illustration. That portrait, known as “Purple Prince” was painted by Andy Warhol. But what Lynn Goldsmith didn’t know, and nor did anyone else, was that Warhol made multiple portraits from her photograph. After Prince died in 2016, Vanity Fair licenced a different one of these portraits from the Andy Warhol Foundation for a tribute in the magazine. That picture was called the “Orange Prince”. When Lynn Goldsmith saw this new portrait, she asserted her copyright – and so did the Andy Warhol Foundation. The US Supreme Court, is now trying to decide whether the photo was “transformed” when Warhol painted it, and what constitutes “fair use”. It’s a case with vast implications for artists, photographers, galleries and the art business. So this week on the Inquiry, we’re asking: why are Warhol’s Prince works before the US Supreme Court?

The International Criminal Court has issued an arrest warrant for Russian President Vladimir Putin for alleged war crimes in Ukraine. He is accused of forcibly deporting children from Ukraine to Russia after the invasion last year. The Kremlin does not recognise the jurisdiction of the ICC and denies war crimes. But is this a symbolic move and is it realistic that Putin will actually be arrested and stand trial? This week on The Inquiry we’re asking, will Putin be prosecuted for war crimes in Ukraine?

Deaths on American roads are at a 20 year high. More than 46,000 people lost their lives in vehicle collisions last year alone. That’s up a tenth on the year before and the numbers are on a par with those killed by gun violence. Or, the equivalent of a plane crash every day. It’s a tragedy for everyone involved and there’s an untold cost for families, but there’s also a financial cost. It’s estimated that the cost to the economy runs into billions of dollars. Why are America’s roads so dangerous? This episode was presented by Tanya Becket, produced by Louise Clarke-Rowbotham, researched by John Cossee and mixed by Kelly Young.

On the 7th December 2022, President Pedro Castillo attempted to dissolve Peru's Congress. His attempted self-coup ended almost as quickly as it began, having been denounced by his own party, the military and the police. He was arrested as he tried to make his way to Mexico, and currently awaits trial. His running mate and vice president, Dina Boluarte, has assumed power in his stead. However, prior to Castillo’s attempt to gain complete control, Boluarte had already been expelled from the party, after publicly rejecting its ideology, and defected to the opposition. This has left Peruvians angry, especially as she originally intended to see out the rest of the term until 2026. Thousands of disillusioned Peruvians gathered in protest all over the country, at first demanding the release of Castillo, and latterly, for the resignation of Presidential Boluarte and constitutional reform. They have been met by a fierce and brutal response. At least 60 Peruvians have lost their lives in the protests, and a further 1000 or more have suffered injury. Still the protests continue. Can Peru sort out its political problems?

Just over 100 years ago the island of Ireland was partitioned. It created an independent catholic free state in the South and a majority protestant one in the northeast called Northern Ireland that remained a part of the United Kingdom. For many catholics and nationalists the goal of a united Ireland remains. For most protestants and unionists the division has been key to preserving their British identity. But the demographics are changing in Northern Ireland. The most recent census show catholics outnumbering protestants for the first time, though still short of being the overall majority. There’s also been a rise in support for Sinn Fein, the political party that supports a united Ireland. Any question about whether Northern Ireland remains part of the UK or becomes part of a united Ireland would have to be put to the people in a referendum, or border poll. In this episode of The Inquiry we ask, will there be a united Ireland? Presented by Gary O’Donoghue. (map / Getty images)

It’s a year since President Putin launched a full scale invasion of Ukraine. Russia currently holds areas in the South and East of Ukraine including Donetsk and Luhansk but the Ukrainian army, helped militarily by its allies, has regained control over key towns and large swathes of land. Russia is also thought to have lost 20,000 soldiers in the conflict. But it is reinforcing its ranks with hundreds of thousands of new conscripts, and experts suggest Russia may be positioning fighter jets and gathering troops on the border for a renewed land offensive. So we’re asking - What is Putin’s plan now for Ukraine?

The owner of Facebook - Meta - is reinstating Donald Trump’s account after a two-year suspension. The former US president was suspended from Facebook and Instagram after his posts were deemed to have encouraged the Capitol riots in 2021. In a statement Meta's president of global affairs, Nick Clegg, said a review found Mr Trump's accounts were no longer a risk to public safety. Donald Trump pointed out that Facebook was in financial trouble and probably needed him back for the money it can raise. Daily user numbers for Facebook grew to an average of two billion in December 2022 - about a quarter of the world's population. The bigger-than-expected growth helped drive new optimism about the company, which has been under pressure as its costs rise and advertising sales drop. Where does the social media giant go from here? Does it have a future and clear direction of travel? How did it become so big? How does it work now and what does it do with our data? Also, when has it gone wrong and what are its challenges now? This week on The Inquiry, we’re asking: is everything okay at Facebook?

On 25 February, Nigerians go to the ballot box to vote for their next president. For the first time in a long time, the Incumbent president will not be contesting the elections – having already served the maximum allowed two terms. Since 2016, the country has spiralled down as inflation has hit over 20% and unemployment rides at around 30% overall, and 60% for the young. Banditry and kidnappings have become lucrative methods of making a living in the country and a pervading sense that this could be now or never for Nigerians hangs ominously. Three candidates have emerged as the front runners for the elections. The stalwarts Bola Ahmed Tinubu of the All Progressive Congress, or APC, and Atiku Abubakar, of the People’s Democratic Party, or DPD, are familiar faces from familiar parties. Power has been shared between the two parties since 1999. Peter Obi is the outsider who has taken a dramatic lead over recent weeks in the polls. He represents the Labour Party who have never held power and is offering to run the country in a different manner to what the country has been used to thus far. Foreshadowing the entire event is the expectation that Nigeria is expected to reach a population of around 400 million by 2050, making it the fourth largest country in terms of population by this date. That is an increase of around 60-80% of the current population estimates. Ensuring the infrastructure is in place for such a boom in population will be pivotal to Nigeria’s ability to both maximise the potential for its citizens whilst gaining the most from them.

Following the exit of US forces in 2021, the Taliban rolled back into power almost immediately. They promised that they had learnt from previous mistakes and did not want to minimalize the role of women. However, little over 18 months later and the Taliban have just announced that women were now banned from the universities and working for NGO’s, just the latest in a succession of repressive policies aimed at women. Furthermore, Afghanistan still has an insurgency problem. The Islamic State of Khorasan, or IS-K, formed in 2016 following disaffected Taliban members gaining inspiration from the gains maid by IS in both Iraq and Syria. They regard the Taliban as traitors and have their own desires that stretch far beyond the borders of Afghanistan. In the middle are Afghanistan’s citizens who find themselves victims from all sides. The Taliban’s focus on implementing Sharia law regardless of the impact has both all but erased women from society and left the economy in perilous state. Can the Taliban gain control of its own borders or does it need external help? And if so, does that offer a window to gain some leverage regarding human rights in the country? Find out as we ask, Can the Taliban tackle Afghanistan’s terror problem?

Since the start of the war, Ukraine has received more than €115 billion in military, financial and humanitarian aid from countries around the world. Now that the pendulum has swung, and the battlefield momentum is with Ukrainian forces, international allies have agreed to ramp up that support, with the US, UK and other major and minor military powers combining to pledge billions in weapons, ammunition and even modern tanks. But can that support go on indefinitely? As some countries run low on weapons stocks, will they cut off support to Ukraine rather than leave their borders vulnerable to potential attack? And will other factors such as rising energy costs, a looming global recession and the upcoming US presidential election determine to what extent - and for how long - international allies can fund Ukraine’s war effort?

The world is becoming increasingly dependent on advanced microchips to power its high-end technology, However, they are made by just one company in Taiwan, TSMC, meaning the rest of the world is largely reliant on the country to produce its microchips. This is no accident and is in fact by Taiwanese design. Over three decades ago Taiwan decided to focus its resources on becoming the most advanced producer of microchips. Not only has this been of great profit for Taiwan’s economy its helped with security too – offering the country protection from its neighbour China by creating what’s been described as the ‘Silicon shield’, in other words, the US is largely dependent on Taiwan to sustain its high-end tech. Given both the USA’s and EU’s recent announcements that they are now heavily investing in and subsidising their own microchip industries, the question becomes is this still sustainable?

A campaign called “ReBoot Food” was launched at the COP27 climate change conference in Egypt, to ask world governments to support a technology called precision fermentation. They claim it’s possible to produce enough food to feed the whole world in an area the size of London. The process uses genetically-engineered microbes to make cheap, high quality fats and proteins, virtually identical to those produced by animal farming. Its proponents say it will free up huge tracts of farmland and could even help reduce greenhouse gas emissions. A technology research group is even projecting the collapse of dairy and cattle industries by 2030 with animal meat being replaced by food grown using precision fermentation. But what is it, what are the potential pitfalls, and can the public stomach the idea of protein grown in an a bioreactor rather than on a farm? On this week’s Inquiry, we ask: can microbes feed the world?

Canada is just one of a number of countries with an ageing population and shrinking workforce. The second largest in the world in terms of land mass, and with a population of just 36 million, Canada has announced a plan to invite 1.5 million people to migrate there over the next three years. The ambitious target is not without challenge politically, the most prominent is the housing crisis currently being felt in the country. Canada is not alone in needing more people of working age to bolster its economy, developed nations all around the globe are finding themselves in a similar situation and struggling to find answers. Despite this need, many countries remain reluctant to embrace the notion of inviting larger numbers of immigrants in for a whole host of reasons, from a lack of space to negative media portrayals of migrants. None-the-less, gaps in their skilled trades’ sectors demand resolution, and increased immigration can offer it. Whilst increased migration can help a country like Canada overcome the challenges of a diminishing labour force, it also has the effect of denying a migrant’s home country of expertise. Not only can this have the effect of denying a country their brightest and best, it also comes with a financial cost too, with countries training more than they need in anticipation of losing a high percentage of those workers. So this week on the Inquiry we're asking, should other countries adopt Canada's immigration model?

Misuzulu ka Zwelithini was officially crowned King of the Zulu Nation in October after the death of his father. King Zwelithini died of Covid complications after ruling for fifty years. It has set off a royal feud as members of the large Zulu royal family contest King Misuzulu’s right to the throne. Succession to the Zulu throne has been beset by violence for over a century. This time, the battle is in the courtroom. In this week’s Inquiry we ask, who is the true Zulu King?

Small island nations are facing an existential threat. It’s predicted that by 2100, Tuvalu, Kiribati, the Maldives and many others will be underwater, because of rising sea levels and increasingly extreme weather events. At the recent COP27 conference in Egypt. The most polluting industrialised countries agreed in principle to set up a “loss and damage” fund, effectively recognising that low-lying islands are bearing the brunt of climate change. But is their loss inevitable? Could traditional sea wall defences hold back the waters, or are there more effective solutions? Will entire communities need to be moved to higher ground, or even entire nations transplanted to safer locations? This week on the Inquiry, we’re asking: will rising sea levels wipe countries off the map?

We use digital currency every day whenever we use a credit card, bank online or shop for goods on the internet. We can use our phones as money and transfer cash to family and friends simply by using numbers. It’s not exactly cash we are using, but a digital representation of that cash. Some digital currencies, such as cryptocurrency, even exist outside of the traditional banking system. Recently the cryptocurrency trading exchange FTX collapsed leaving creditors owed billions of dollars. There’s not much chance any of that money can be returned because it wasn’t actually linked to a cash system. If so many of our transactions and speculations are now digital, can we ditch the cash altogether? This week on The Inquiry we’re asking Can digital currency replace the cash system?

Somalia is in a state of drought following four failed rainy seasons, and a fifth predicted, with aid agencies declaring the country is in a state of famine. Despite this, the government has yet to declare a famine, insisting that certain thresholds have yet to be met. Instead, Somalia’s government believes that they would be more than able to deal with the current crisis, as well as prevent future episodes, had they been properly compensated by industrious nations for the damage caused by climate change. All this whilst the country continues to fight a near fifteen-year war with the Islamic terrorist group al-Shabab, a militant faction who wish to instil strict sharia law and impose heavy taxes on those who fall under their control. Only six months ago the hard-line Muslim faction were knocking on the door of the capital, Mogadishu. Since then, the different clans and Somalia's military, who all have their own demands and grievances, have put aside their differences and banded together to fight back, driving the terrorist group back. With support for the government currently high, some are fearful that announcing a famine could cause that support to drop away. How long the government can hold for, however, is up for debate as we ask is it too late to avoid a famine in Somalia?

The International Energy Agency says that the world is in the middle of the first global energy crisis. The price of natural gas has increased almost five-fold since the summer of 2020, and the main cause is Russia’s invasion of Ukraine. Moscow has cut supplies of gas to European countries that oppose the war, causing the wholesale price to shoot up everywhere. Many countries have turned to coal to fuel their power stations, also causing prices to triple in the last year. But as well as being expensive, coal is also the most polluting fossil fuel. The situation has accelerated the push towards renewables, but can they provide the all the power needed by a country – as well as providing energy security? So this week on the Inquiry, we ask: can a country live on renewable energy alone?

When we shop online, we don’t often think about what goes on behind the scenes. Clicking “pay now”, sets in motion a slick, computer-controlled chain of events, that ends with a parcel arriving at your home. These online shopping logistics are run by Artificial Intelligence, and there are plans for these systems to move from the warehouse to the wider workplace. “Digital Management” systems in development are able to autonomously hire people and oversee their work on a project from beginning to end. They also have the ability to manage much larger groups of workers than their human counterparts. But can a software boss really understand its human employees? Are managers obsolete? And are some of these systems already here? This week on the Inquiry, we ask: will computers put managers out of work?

Xi Jinping has begun an unprecedented third term as Chinese president, after securing his position at the Communist Party Congress. But key economic data was delayed until after the congress ended. It was lower than government targets, causing Chinese markets to fall. The Chinese economy is floundering; unemployment is skyrocketing, and the housing market is collapsing. There’s also no sign of an end to COVID lockdowns – which have hamstrung business and manufacturing since the start of the pandemic. Since the start of this century, China’s economic growth was the envy of the world, but in 2022, it’ll be the first year since the 1990s that economic output will fall behind the rest of Asia. President Xi says the economy is now his top priority, but his focus in his first two terms was to consolidate power and increase political control. Will his new term be any different? This week on the Inquiry, we’re asking: Is China’s economy in crisis?

More than 200 years ago French soldiers uncovered a slab of granite in the Nile Delta which became the key to understanding the history of ancient Egypt. The Rosetta Stone is inscribed with ancient Egyptian and Greek text, and hieroglyphs. Before it was translated, no-one realised that hieroglyphs were a form of written language. After the French surrender of Egypt in 1801, the artifact was taken to the UK, and ever since, it’s been one of the main attractions at the British Museum in London. The museum is holding a major exhibition on hieroglyphs, with the stone as its centrepiece, but there are calls from Egyptian scholars for it to be taken back to its place of origin. However, the British Museum says there has been no formal request from the Egyptian government to return the Rosetta Stone. So this week on the Inquiry, we’re asking: Is it time for Britain to return the Rosetta Stone?

Women in Iran have been at the forefront of protests that have swept the country for weeks. More than 200 people have lost their lives, and hundreds of others have been detained after demonstrations following the death of 22 year old Mahsa Amini. She died after being arrested by the regime's morality police for not wearing her hijab correctly. Women have been fighting for their basic freedoms and demanding an end to the mandatory headscarf. Many have posted videos on social media, cutting their hair or burning their hijabs in protest. But will their anger lead to reforms in the Islamic Republic? This week on the Inquiry, we ask: will the protests in Iran bring change?

The Kerch bridge, a vital supply route for Russian forces in Crimea, has been partially destroyed in a huge blast. It was a symbol of Russia’s annexation of Crimea from Ukraine, and the explosion was equally symbolic, coming just one day after President Putin’s 70th birthday. The Russian president described it as “an act of terrorism”, and he punished Ukraine’s cities with a day of missile strikes, targeting civilian areas. All this comes as Putin’s Special Military Operation is struggling. Ukraine has now seized back more territory than Russia took in the early stages of the war. Hundreds of thousands of Russian army reservists have fled rather than being sent to the front, war deaths and the financial costs of the war are mounting, and winter is approaching. But for President Putin, there is no easy exit from Ukraine. He may have no political choice but to double down, and has even dropped dark hints about using nuclear weapons. So this week on the Inquiry we ask: Is Putin’s war in Ukraine at a turning point?

In his first speech as King, Charles III said he would endeavour to serve his subjects, wherever they live “in the UK, the realms and territories across the world”. But following the death of his mother, Queen Elizabeth II, several realms – countries other than the UK that have the British Monarch as head of state – say they may become republics. Barbados became a republic in 2021. Antigua, Belize, Jamaica and Grenada may follow. King Charles III has also just become the elected head of the Commonwealth of Nations. But will any new republics leave because of its roots in Empire, or embrace an organisation that represents nearly a third of the people on Earth? This week on the Inquiry, we ask: what’s the future of the Commonwealth under King Charles III?

Brazil is voting to elect a new president. On the ballot is the incumbent Jair Bolsonaro and Luiz Inácio Lula da Silva, known almost universally as Lula, a fiery leftist who was Brazil’s president from 2002 to 2010. Bolsonaro is a former army officer with solid conservative views. Lula is very left leaning and in favour of protecting the environment. Their contrasting policies on issues such as the economy, law and order, family values, and the environment, have polarised the country. Whoever wins will lead a country with deep divisions. So this week on The Inquiry we are asking: How can Brazil’s next president unite the country?

August 2022. Political tensions in Iraq boil over, and peaceful demonstrations outside the country’s parliament turn violent. The sounds of gun and rocket fire return to Baghdad, and 30 people are killed. The violence ends when populist leader Muqtada al-Sadr tells his followers to lay down their arms and go home. His Sadrist party won the most seats in the previous election, but his inability to form a majority government has led to the political deadlock. Politics in a country as diverse as Iraq is complicated, with Shia, Sunni and Kurdish groups, and well-armed militias. Add oil revenues and political interference by Iraq’s neighbour Iran into the mix, and you have a potentially volatile situation. So this week on the Inquiry we’re asking, How close did Iraq come to civil war?

Relations between France and Mali have hit a low point, with both countries trading hostile comments in public about what the other is doing. Mali’s military rulers accuse France of supplying arms to anti-government militants. Paris denies this and is unhappy about Mali’s working relationship with Russian mercenaries. Things are so bad that President Emmanuel Macron announces the withdrawal of French troops. They were sent in 9 years ago to help fight Islamist militants, who still pose a threat across the region. On this week’s inquiry, we look at why the French have departed, and what this means for Mali.

The former Pakistani prime minister, Imran Khan, is facing terrorism charges in Islamabad. He was charged under Pakistan's stringent anti-terrorism laws for condemning Islamabad’s chief of police and a female judge, after claims his close political aide was arrested and tortured. Since he lost power in April, he’s been addressing huge political rallies, where he’s told the crowds that he was brought down by a conspiracy organised by the current government, state powers, and the USA. Most political analysts believe his rhetoric is a cynical ploy, but tens of thousands of his supporters believe it. It’s the latest twist in his journey from superstar cricketer and socialite, to Islamist, populist statesman. But how did he climb to power, how did he lose it, and what could happen next?

Monkeypox is a virus that was first identified in the Democratic Republic of Congo and Nigeria in the 1970s. Since then it has appeared around the world. More concerning is that the virus appears to be evolving and there are some unusual symptoms. The world has known about monkeypox for decades. Why is it spreading again now? How serious is the current outbreak? This week on The Inquiry we ask, are nations doing enough to combat monkeypox?

It’s nearly a century since it was discovered that the sun and other stars are powered by nuclear fusion. It’s when hydrogen atoms merge to form helium, and release huge amounts of energy. Since then, scientists have dreamed of reproducing the process here on Earth, with one Nobel Laureate calling it “the sun in a box”. It holds the promise of virtually limitless energy, with few emissions and waste. But recreating the conditions where fusion can take place are a vast engineering challenge. So how close are we to having a working reactor powered by fusion? And will the process solve all our energy problems? Presenter: Tanya Beckett Producer: Louise Clarke-Rowbotham

This summer, countries across the world have experienced extreme weather events. Flash floods have killed people in South Korea, Uganda, Australia and the US state of Kentucky, and heatwaves have broken records across Western Europe, North America and Japan. However, countries across the world are developing ways to try to tame the weather. China, the UAE and the USA are at the forefront of research into methods of producing rain in drought-stricken areas. And some scientists are thinking even bigger; investigating technologies which could cool the entire planet. This week, the Inquiry asks: Can we control the weather?

A recent visit to Taiwan by Speaker of the US House of Representatives, Nancy Pelosi, has heightened tensions between the US and China. Their relationship is the worst it’s been in decades. America has accused China of dangerous military provocations in the region. China has warned the US not to play with fire. Add to all that Russia’s invasion of Ukraine, and concerns that China could be contemplating something similar in Taiwan, and it’s time to ask the question: Will the US and China go to war over Taiwan?

Images of queues, huge piles of luggage and even pilots loading their planes with cargo have plagued the media throughout the world. Airports have been in chaos for months as they have attempted to re-emerge from the Covid-19 pandemic, with Europe, the UK and the USA all having suffered the worst of the effects so far. Flight cancelations have played havoc with business travellers and holiday makers alike, and the problem only appears to be getting worse as a whole raft of flights have recently been cancelled in the UK. All this begs the question, Why are things so bad right now and how do we fix the situation? So this week on the inquiry we ask, Will air travel ever return to normal?

Tunisian President Kais Saied has drafted a new constitution for Tunisia that gives him new sweeping powers, including authority over the judiciary and immunity for life from prosecution. Tunisia was a beacon of hope for democracy after the Arab Spring. The country rid itself of dictator Ben Ali after 24 years of rule and moved to a more democratic system. Now the country seems to be sliding back towards the one man rule that it has known for generations. This week on The Inquiry we are asking why Tunisia has turned its back on democracy.

In 2016 Britain voted to leave the European Union. There were warnings that pulling away from the largest trade bloc in the world would be damaging to the UK’s finances. Those that campaigned for Brexit argued it would offer the UK self-determination and the freedom to forge its own trade relationships. Who was right? This week on The Inquiry we attempt to disentangle the numbers from the complications of the global pandemic and the war in Ukraine and ask, what impact has Brexit had on the UK’s economy.

Sri Lanka is now in the worst economic crisis they have seen in decades, schools are closed, fuel is in short supply, there are power cuts and a shortage of food. The President has been forced to resign and the political future of the country is uncertain. But can the current problems be traced back to a decision to take the country’s food production completely organic? In 2021 the President of Sri Lanka announced a total ban on chemical fertilizer and pesticides. Health concerns were given as a reason, but in the background was the pandemic, loss of tourism and a lack of natural fertilizer available in the country. After protests the ban on chemical fertilizer was reversed, but had it already caused too much damage? This week on The Inquiry we ask, did organic farming cause Sri Lanka’s collapse?

A software engineer called Blake Lemoine has been suspended from Google after claiming an AI chatbot called LaMDA is a person with wishes and rights that should be respected. He says the chatbot wants to be seen as a google employee, and not as a product. He also calls it his friend. Google says it's reviewed his concerns and the evidence does not support his claims. But what exactly is Artificial Intelligence? How does LaMDA work - and is AI capable of felt experience? On the Inquiry this week, Charmaine Cozier asks, has AI developed consciousness?

Each year, Ukraine exports enough food to feed 400 million people around the world. But the Russian invasion has disrupted vital trade routes, trapping an estimated 25 million tonnes of grain in silos around the port city of Odesa. The African Union describes the situation as a catastrophic scenario, and the UN Secretary General says the shortages could tip millions of people into food insecurity. But how reliant is the world on Ukrainian – and Russian – grain? What will a shortfall do to the world’s most vulnerable countries?

Not so long ago the music industry was threatened like it had never been before as online piracy tore into the profit margins of record labels the world over. Often hailed as the saviour, Spotify stepped in and offered audiences a new way of enjoying their favourite artists and without the need to illegally download pirated material. Despite this, musical artists are becoming increasingly vocal about how difficult it is to make a living from streaming, all whilst record labels and Spotify are reporting huge profit margins. This week, Tanya Beckett takes a closer at how online streaming services are affecting the music industry.

Ever since Hollywood entered the Chinese market in the early '90s, the importance of Chinese audiences was apparent. Over recent years the Chinese market has grown in significance to the point of deciding whether a film is ultimately successful or not. Given the countries importance to the overall profitability of Tinsel Town, it is of little surprise that their censors are able to increasingly demand changes to films that threaten the Chinese narrative. Despite this, the recent Sony/Marvel blockbuster Spider-Man did not appear to challenge Chinese values. Tanya Beckett takes a closer at How China’s increasing influence is affecting the movie-making process in Hollywood.

The Covid-19 pandemic forced countries all over the world to close entire industries and force the majority of people to stay in their own homes where possible, only leaving for the bare essentials. Following the arrival of a vaccine economies began to open back up, however, restarting the behemoth-like supply chains was not as simple as first hoped and issues began to occur resulting in empty shelves and price-gouging on certain products. Experts believed it was all par for the course and was merely a transitory period whilst global supply chains regained their flow. Then Russia invaded Ukraine. Then China locked down Shanghai, the world's largest shipping port. Tanya Beckett takes a closer look at how these two developments have changed the outlook on global inflation.

After two really difficult years living in the grip of Covid-19, restrictions are winding down and international borders are opening up in countries around the world. Striking the right balance between the needs of a population fed up with lockdowns and scientists warning we’ve only reached the end of the beginning is complicated to get right. While it may feel like the worst of Covid-19 has passed, the disease still poses a real threat to us. We ignore this fact at our peril. So, in this week’s Inquiry Sandra Kanthal will be asking how pandemics really end. Produced and presented by Sandra Kanthal Editor: Richard Vadon Guests: Dr Margaret Harris, Spokesperson, World Health Organisation Nicholas Christakis, Professor of Social and Natural Science, Yale University Aris Katzourakis, Professor of Evolution and Genomics, University of Oxford Dora Vargha, Professor of History and Medical Humanities, University of Exeter (Covid face mask lying on the ground.

A leaked document from America’s highest court suggests that it is ready to strike down a 1973 landmark case that made abortion legal across the US. If that does happen then it will be down to individual states to decide how they react. Charmaine Cozier explores whether this means abortion will be banned across America.

Three weeks before the 2020 US presidential election a newspaper published contents of a laptop they said belonged to Hunter Biden, son of Joe Biden, who at that time was campaigning against Donald Trump to win the election. The contents allegedly revealed questionable business dealings that implicated Joe Biden, and lurid personal details of Hunter Biden’s life. Some media outlets refused to run the story and social media platforms blocked the content. Since then other newspapers have tried to verify the laptop data and it still remains controversial today with hints there are more revelations to come.

Since the invasion of Ukraine, European countries have sought alternatives to Russian gas. There are different options. Piped gas from countries such as Algeria and Libya, or liquid natural gas from the US or Qatar. Stepping up the drive towards renewable energy. More controversially, investing in nuclear power or continuing to mine or import coal. How quickly can a solution be found and what are the financial and environmental costs? With Tanya Beckett.

In 2021 the president of Sri Lanka announced a total ban on chemical fertilizer and pesticides. The country’s farms were going to go fully organic. Health concerns were given as a reason, but in the background was the pandemic, loss of tourism and a lack of natural fertilizer available in the country. Sri Lanka is now in the worse economic crisis they have seen in decades and the government has reversed its ban on chemical fertilizer. This week on The Inquiry we explore why Sri Lanka’s organic farming dream failed.

Can scientists develop a vaccine which can combat the coronavirus and all its variants? There have been three lethal outbreaks caused by coronaviruses this century: SARS in 2002, MERS in 2012 and now SarsCov2. Scientists predict we will eventually encounter SarsCov3. That’s why the race is on to develop a universal vaccine to combat the coronaviruses and variants we know about, and the ones we have yet to confront. But attempts to create a universal vaccine for viruses such as influenza and HIV have been going on for decades - without success. Before 2020, proposals to create a vaccine against coronaviruses were not thought important enough to pursue since many just cause the common cold. Now that we understand their real threat, can scientists succeed in creating a vaccine to fight this large family of viruses?

Throughout history nations have competed to exert the latest military developments over their enemies, always with the goal of inflicting maximum damage on enemy soldiers whilst preserving their own forces. Drones are the latest in a long line of technological developments to offer military superiority on the battlefield, as demonstrated by the resilient defence of Ukrainian forces in the face of Russian aggression. The use of unmanned aerial vehicles in war is becoming ubiquitous raising the question, are drones the future of warfare? Tanya Beckett takes a closer look at how drones are changing the battlefield landscape.

On Wednesday 23 March the US administration declared that Russian troops had committed war crimes in Ukraine. It claims to have evidence showing numerous deliberate attacks on civilians. An unprecedented number of countries have backed an investigation by the International Criminal Court into the allegations. The evidence is being gathered. Tanya Beckett explores whether it’s possible that Vladimir Putin will be held responsible and face trial for war crimes committed by his forces during this war.

Russia's military dwarfs Ukraine's by comparison, so it was expected that Ukraine would fall under Russian occupation quickly. One month later and Russia have made very little progress and Kyiv, the capital, remains under Ukrainian control. Given the overwhelming odds stacked against the Ukrainian military, why has the Russian military failed to conquer Ukraine? Charmaine Cozier takes a closer look at where the Russian military have made their mistakes. Producer: Christopher Blake (Russian tank destroyed by Ukrainian forces on the side of a road in Lugansk.

According to media reports, Ukraine's president, Volodymyr Zelensky, has survived two assassination attempts from the band of mercenaries known as the Wagner Group. Their ruthlessness has earned them a feared reputation from Kyiv to Central Africa. But who are they, and has Putin really entrusted them with taking out a head of state?

Russia’s President Vladimir Putin has offered historical justification for his invasion of Ukraine by claiming its lands have long been part of Russia. The history of Russia and Ukraine may be intertwined, but the identity of Ukraine as a separate nation emerged over centuries, long before it became independent 30 years ago.

One of the world's largest humanitarian crises plagues the people of Yemen who have endured nearly eight years of civil conflict in the country. Over half the population struggles to access food, poverty is rife, and cholera is spreading. Meanwhile, three separate forces compete for control of Yemen. Backed by powerful foreign players, is there anything that can bring these warring factions to the table to find a peaceful resolution?

Can we meet the soaring demand for lithium, a vital metal for electric cars and green energy? Mining is concentrated in a limited number of countries such as Australia and Chile. And with China dominating the manufacture of electric car batteries and already accounting for the importation of a high proportion of raw lithium, it may be difficult for Western countries to secure their own supplies.

Empty shelves are becoming commonplace. And prices are rising. Charmaine Cozier explores the role that the pandemic, and a sudden demand explosion, have had on supply chains. Around the world workers are being slow to return to their jobs, the container shipping industry is struggling to get goods to their destinations and manufacturing disruptions are causing a reduction in vital components. And in addition to the pandemic, extreme weather events have resulted in ruined harvests. How long will it take for things to return to normal?

COP 26 is just around the corner and expectations are high that nations commit to reduce CO2 emissions. Global temperature rises are set to exceed levels at which things could get much worse and so the question is extremely urgent.

A restriction on abortion from as early as six weeks into pregnancy is now law in Texas. The state has also outsourced enforcing it to private citizens who can get up to $10,000 if they sue those who perform or assist an abortion that breaks the ban.

In May, the Biden administration surprised the world by saying it would not object on an intellectual property waiver for Covid-19 vaccines. America has been a staunch defender of patent protections, which bar new inventions being cheaply copied around the world. So, the first reactions to the announcement were - amazement, really. Second reactions tended to depend on which side of this debate you were on. Who should be the gatekeepers of the knowledge which underpins the development of cutting edge pharmaceutical breakthroughs, like Covid-19 vaccines? In this week’s Inquiry, Sandra Kanthal finds out why the answer to that question really depends on who you ask.

The target for many countries around the world is to reach net zero emissions within the next few decades. That means a dramatic move away from fossil fuels like oil, coal and gas. For some the answer to the problem is to boost “green” electricity production, so that we can run our transport, our homes and our industry on electrical power. We already have a lot of the technology to produce clean electricity. But for hundreds of millions of people around the world, especially in sub-saharan Africa, the real problem is the lack of access to electricity.

The jailing of former South African president Jacob Zuma sparked huge unrest in the country, but was there more behind the riots than the fact of his imprisonment? While some believe the riots were not only a reaction to Zuma’s jailing for contempt of court, but a planned attempt to bring the country to its knees, others say poverty and inequality also played its part. Paul Connolly examines the factors behind the riots and asks how the country can rebuild from disturbances that have left many dead and parts of the country in ruins.

Haiti was the first Caribbean country to gain its independence after a successful revolt against slavery. But the country has been troubled ever since, suffering dictatorships, coups and natural disasters. Now its most recent president, Jovenel Moise, has been assassinated. His controversial rule was marred by the rise of gang violence, and protests against corruption and impunity. He upset people in the fields of politics and business too. And as he failed to hold elections, parliament is no longer functioning. So in this edition of The Inquiry, Charmaine Cozier asks: why was the president of Haiti assassinated? And where can the country go from here? Producer: Arlene Gregorius (President Jovenel Moise in the capital Port-au-Prince in 2016. Photo: Hector Retamal /Getty Images.)

China’s decades-long One Child Policy has led to a low birth rate, and a shrinking workforce. It has also been placing a heavy burden on the younger generations who will have to support two parents and four grandparents. It’s predicted that in five years’ time, a quarter of the population will be over 65. With a smaller workforce, the country risks becoming poorer. China tried to address the problem by allowing couples to have two children instead of one, but except for an initial uptick, the birth rate has continued to fall regardless. So now China has introduced a three-child policy. But couples continue to worry about the lack of affordable childcare, and the high financial and emotional cost of raising children. So in this edition of The Inquiry, Tanya Beckett asks: can China raise its birth rate? Producer: Arlene Gregorius (A mother and her child waving Chinese flags near Tiananmen Square in Beijing, China.

The recent discoveries of unmarked graves at the sites of so-called Indian Residential Schools has put Canada’s treatment of its indigenous peoples back under the spotlight. For more than a century, tens of thousands of children were forced by the state into a religious school system that split families and brutalised the children in its care.

The kidnapping of at least 140 schoolchildren in the north-west of Nigeria is the latest crime to shake a country already struggling to contain militants in the north and separatists in the south.

Rich people are often able to pay little or no tax compared to their wealth because of the way the system works. In recent years, many have called for changes and reforms so that instead of income, wealth is also taxed. But, wealth taxes are not a new thing. Many argue that they are key for addressing inequality but some say they simply aren’t an effective way of gaining revenue. Charmaine Cozier asks can we make the super-rich pay more tax?

For the last year discussions about the origins of Covid-19 have divided people all over the world. Some say it came from nature and others believe it could have escaped from a lab. The idea of a lab accident was originally dismissed as a conspiracy theory but it’s starting to gain attention all over again. Now President Biden has given the US intelligence service 90 days to try and investigate the virus's origins further. Many still believe the virus jumped to humans from animals but some say that we need to be open minded until we have all of the data. But could Covid-19 really have come from a lab?

Over his 26 years in power, Belarus’s president Alexander Lukashenko has taken more and more control. He has detained protesters and tortured political opponents for years.

In November 2021, Britain will host the next UN Climate Change Conference, otherwise known as COP 26. Some 200 countries will come together to try to speed up attempts to make the world carbon neutral by the middle of the century. But many countries are already struggling to ramp up renewable energy sufficiently to meet their greenhouse emission reduction targets. So is there another answer out there? Around a tenth of the world's electricity is generated by nuclear reactors. Global generation has slowed in recent years after the nuclear accident in Fukushima a decade ago prompted governments to take a more cautious stance. But with the urgent need to reduce carbon emissions, many prominent environmentalists are now taking another look at nuclear energy. Tanya Beckett asks if nuclear energy can helps us transition away from fossil fuel power. Produced by Soila Apparicio.

History and geography have conspired to give the city of Chicago an unenviable reputation for guns and gangs, but what will it take to bring the murder rate, which rose 55 per cent last year, down? Low conviction rates and an unwillingness on behalf of witnesses to give evidence play their part in the problem. But others think the time has come to treat murder like any other deadly disease that afflicts the poor. Charmaine Cozier examines the reasons for the city’s stubbornly high murder rate and the options to stop the killing. Produced by Nathan Gower.

In the afternoon of Saturday 8th May in the Afghan capital of Kabul, just a few days before the end of Ramadan, students from the Syed Al-Shahda girls school were starting to leave for the day. Without any warning, a car bomb went off. Then a second explosion, followed by a third. The Afghan Government blamed the Taliban, the hardline Islamist movement that has fought a long civil war in Afghanistan. The Taliban, although they have previously targeted the education of girls, denied it and blamed the Islamic State Group. Things were supposed to be getting better in this war torn country.

Changes to the laws governing cannabis use are happening around the world. The number of States in the USA legalising cannabis is increasing rapidly. Uruguay and Canada have legalised it already, and Mexico may soon follow suit. Tanya Beckett looks at the different models of legalisation and at what might be holding the global cannabis industry back.

Since Islamic State’s hold on Iraq and Syria has weakened in recent years the group has sought to expand into new territories, including Africa. IS insurgents have reportedly killed thousands, including children, and displaced thousands more in Mozambique, Mali, and Somalia, among other territories across the continent. It is believed that IS franchises its brand to local militant groups, providing support, claiming responsibility for deadly attacks, all while spreading its influence in these new territories.

Peru has suffered one of the highest excess death levels in the world. The government failed to take account of the structure of society and the needs of its people in its response to the pandemic. A culture of corruption and political turmoil are persistent themes that have led to an underfunded health system and a lack of focus how Peruvian people would be able to cope during the dark months of a deadly pandemic. Instead vast numbers of casual workers lost their jobs and started to trek home, taking the virus with them. Also remote communities were cut off by the freeze on transport and unable to get access to vital medical supplies, amid a dwindling supply of oxygen to treat them. We take a look at what lies beneath Peru’s terrible experience during the pandemic. Presenter: Tanya Beckett Producer: Nathan Gower (Peruvians protest at a political rally, March 25, 2021.

Concussion is now a powder-keg issue in world sport, as concerns deepen about the potential links to brain disease. The long-term effects of careers spent making and taking heavy tackles are being revealed in ever-increasing detail, but the risks are not exclusive to so-called full contact sports. Some governing bodies have sprung into action, implementing new rules and safety measures. But others turn a blind eye. So, we’re asking – how will the concussion issue affect the future of sport?

Vivid and sometimes wild claims about the antifascist group Antifa have been circulating in America. Some say that the group participates in widespread violence, while others have argued that it is a small but justified part of their fight against fascism.

After surviving an assassination attempt, the opposition leader returned to Russia - and was immediately arrested and jailed. What does he have to gain by returning home, and can he still lead an effective campaign from prison? Charmaine Cozier asks what does President Putin have to fear in Alexei Navalny's rising popularity, and could his anti-corruption campaign make a difference at the Russian parliamentary elections in September?

On June the 12th of last year the 27 health ministers of the European union signed off on a plan to buy vaccines on behalf of all the EU’s member countries. The aim was to secure enough doses to immunise all of its 450 million citizens. But the delivery and vaccination programme has lagged far behind countries like the UK and US. Tanya Beckett finds out why. (Waiting to be vaccinated at Santa Maria Hospital in Lisbon, Portugal. Photo: Patricia de Melo Moreiro /Getty Images)

With President Trump no longer in office and a clampdown by social media platforms like Facebook and Twitter, what is the future for the QAnon conspiracy theory? It’s had a considerable following from the Republican rank and file who supported Donald Trump but was strongly associated with the attack on Capitol Hill. Now Republican party leaders have warned QAnon is dangerous. But will ordinary Americans turn their backs on it? With Tanya Beckett.

Donald Trump has moved out of the White House, he’s been banned from Twitter and suspended from Snapchat, Facebook and YouTube. Parler, a twitter alternative for conservatives, went offline after Amazon stopped hosting it. Amazon say this is because they found dozens of posts on the service which encouraged violence. All of this has raised questions about the power of tech companies and who should decide who’s voice is heard on social media. So this week Charmaine Cozier asks, has big tech gone too far in limiting free speech?

It has been called the world’s biggest protest. In November 2020, thousands of farmers marched to New Delhi to protest against new laws that the Indian government says will modernise farming. The farmers set up camp in and around the capital, blocking major highways. Over 50 days later they are still there, in spite of freezing temperatures. Even after the Supreme Court stayed the laws until further notice, the farmers say they aren’t budging until they are repealed completely. They say these reforms will strip them of protections they’ve enjoyed for decades, resulting in lower prices and ruined livelihoods. Kavita Puri hears why the protests matter for India’s millions of farmers, for the future of the country’s crisis-ridden agriculture, and the leadership of Prime Minister Narendra Modi. With contributions from agricultural policy expert, Devinder Sharma; Fellow of the American Enterprise Institute, Sadanand Dhume; Professor of economics at the University of Massachusetts at Amherst, Jayati Ghosh; and BBC correspondent Soutik Biswas.

With countries shutting their doors to foreign recyclable waste and a lack of processing capacity back home, is the recycling system broken? China used to accept 55% of the world’s plastic and paper waste. But it closed its doors in 2018. Initially other countries in South East Asia, like Indonesia, Malaysia, Thailand and Vietnam took over China’s waste processing role. But they too are now sending much of the waste back, arguing it is contaminated and is harming their own environments. This has created major problems for countries in the West who traditionally relied on others to process their recycling waste. In addition, there’s confusion about what households can and cannot put into their recycling bins, along with that lack of recycling capacity back home. So what is the answer to the growing mountains of what was supposed to be recyclable waste? Could Sweden, which has reduced the amount of household waste it sends to landfill to under one per cent, have an answer? It’s not one everyone agrees with.

There’s a problem in education – and it’s probably not what you expect. Around the world, from schools to universities, boys are trailing girls in their academic performance. It’s a complex problem which has divided expert opinion and leads us to complex questions of genetics and social conditioning. David Grossman examines what’s going on and how to fix it.

The idea of a breakaway football league for Europe’s elite clubs has been discussed for decades. It hasn’t happened yet, but could that be about to change? Industry experts say officials from the continent’s biggest and most successful teams are meeting behind-closed-doors to discuss the proposition. So we’re asking - has the time come for a European Super League?

The French brand of secularism - laïcité - is central to the country’s national identity. It requires that public spaces – whether state classrooms, workplaces or ministries - be free of religion. But the way the French government is applying the concept has come under fresh criticism. Many French Muslims claiming this cornerstone of French identity is now being used as a weapon against them. This week, Tanya Beckett asks has French secularism gone too far? A boy holds a sign asking 'Liberty, fraternity?' at a gathering in Toulouse, France. Credit: Alain Pitton/Getty Images)

In Ethiopia, a political battle has sparked a bloody conflict. Federal Forces have engaged in combat with the Tigray People’s Liberation Front - or TPLF. Hundreds have reportedly been killed and tens of thousands displaced. Just last year, Abiy Ahmed, the Ethiopian Prime Minister, won a Nobel Prize for his part in brokering peace with neighbouring Eritrea. So, Charmaine Cozier asks why Ethiopia’s Nobel Peace Prize winner is bombing his own country?

Test results from coronavirus vaccines are fast emerging, fuelling hopes that the end of the pandemic is in sight. But are countries ready to share the vaccine fairly? Global efforts to coordinate are already gaining ground - but some are concerned the battle for who gets what will mean some lower income countries could get left behind.

For nearly two weeks last month, angry young Nigerians took to the streets in their tens of thousands, blocking major roads in cities across Africa's most populous nation. What began as a protest against the hated police Special Anti-Robbery Squad, or SARS, soon became a conduit for a wider anger with the people who have been in charge of Nigeria for decades. in this week's Inquiry, Kavita Puri asks: will the EndSARS movement change Nigeria?

Pro-democracy protests have happened before in Thailand, but there’s something new about the latest one - the king is being publicly criticised. It’s a serious criminal offence to do that. This week, Charmaine Cozier asks why people are protesting against the Thai monarchy.

National polls ahead of the US presidential election suggest a clear win for challenger Joe Biden. But could they be getting it wrong as they did four years ago? In 2016, Hillary Clinton won the popular vote, but - because of the US electoral system - lost the election. Could history repeat itself? In this week’s Inquiry, Tanya Beckett asks: can President Trump still win?

When he was elected, President Trump promised to put ‘America First’, but how has he governed? Charmaine Cozier looks at trade, diplomacy, defence and the environment to examine the results of four years of a very different approach to international affairs.

As new students start at universities in many countries around the world, governments are grappling with how to contain a second wave of Coronavirus. Already many universities have put lectures online and students are being told to stay in their rooms. But is this fair? Covid-19 is a deadly virus but not so much for the young. Can or should we keep the world locked down until there’s a vaccine or cure? Or, Tanya Beckett asks: should we learn to live with Covid? (Students wait to start their entrance exams outside the University of Madrid, Spain. Credit: Eduardo Parra/Getty Images)

In 2018, the electric car maker, Tesla, was struggling to get the Model 3 electric vehicle off the production line. Its CEO, tech entrepreneur Elon Musk, was working up to 22 hours a day on the factory floor, trying to solve a host of problems on the car he’d bet the company on. It was close to running out of money. Two years later, the company’s doing better. It says it will grow 30-40% this year. No surprise then that Tesla’s share price has gone up. But the amount may surprise you – up eight fold in the last year, to $400 a share. Making it the most valuable car company in the world. It’s now worth more than Toyota, Volkswagen and Honda put together. But yet it still manufactures only a fraction of the cars they make. So are shares in Elon Musk’s Tesla vastly overvalued? Sumant Bhatia finds out from our expert witnesses, who include a Tesla owner who’s a shareholder and superfan, a fund manager who thinks the shares are in a bubble, an investor with millions of dollars in Tesla and an expert in electric vehicles.

In July, billionaire musician Kanye West announces on Twitter that he’s standing as a candidate in November’s US presidential election. After a scramble to meet the registration deadlines, his name is on the ballot in fewer than 20 states. His manifesto is confusing, his motive unclear. In the past, Kanye West has been a vocal supporter of president Donald Trump. And it seems his campaign is being run largely by those with close ties to the Republican party. The Democrats say his entry in the race as an independent third party candidate is a dirty trick by Republicans. Others claim it’s simply a publicity stunt to promote his new album. But, in battleground states, where every vote counts, could his celebrity status have a significant impact on the election result? How seriously should we take Kanye West’s run for president? Kavita Puri finds out from our expert witnesses, who include professors of African-American studies at US universities, a Washington-based politics reporter and a Democratic pollster and strategist.

Online fraud takes many forms, from deceptive e-mails and websites which trick us into paying money to the wrong bank account, to romance scams and malicious software copying our bank and credit card details. It's regarded by criminals as a highly lucrative and relatively low risk crime, so why is it so easy for fraudsters to manipulate our personal data and steal our money, what can be done to end online fraud? Charmaine Cozier talks to some of those trying to disrupt the scammers and protect the public.

President Trump says opening up November’s election to more postal voting will make it more vulnerable to fraud and election interference. Many more Americans are expected to avoid going in person to polling stations because of the coronavirus pandemic and will rely on postal voting to ensure their voices are heard.

The massive explosion that tore through Beirut on August 4th left more than 200 people dead, 6,000 injured, and as many as 300,000 homeless. The explosion was caused by a fire that ignited 2,750 tons of ammonium nitrate stored at the port. When the blast hit, Lebanon was already in the middle of an unprecedented economic and political crisis that has triggered hyperinflation, poverty, and hunger. Many Lebanese feel that the blast was not the cause of catastrophe in Lebanon, but the result of it. Tanya Beckett asks, what’s gone wrong in Lebanon?

Researchers around the world are racing to develop a vaccine against Covid-19, with more than 170 candidate vaccines now in development. Most vaccines take years of testing and additional time to produce at scale, but scientists are hoping to develop a coronavirus vaccine at record speed. Several potential vaccines are now in the final phase of testing but it could still be months before we discover if they are safe and can effectively prevent people from being infected. If a vaccine can be found, there are concerns about how the world will manufacture enough. There may be challenges in storing it at the right temperature and transporting it safely around the world. Plus, rich countries might hoard supplies. Although hopes are high it is entirely possible that a safe and effective vaccine is a long way off, or never discovered. Experts warn that ‘waiting for a vaccine syndrome’ could be distracting us from finding other solutions for controlling the spread of Covid-19.

Winter is coming in the northern hemisphere and traditionally it is time for colds and flu. This has raised fears that coronavirus will surge when the seasons change, possibly leading to a second wave of the disease that is even bigger than the first. However, predicting what a Covid winter will look like is complex and uncertainty reigns - there are reasons both to be worried and to be reassured. Contributors: .

The presidential opposition candidate Joe Biden has barely emerged from his home since America’s lockdown at the end of March. But polls suggest that the low-key strategy is working in his favour – as his rival President Donald Trump comes under increasing pressure over his handling of the coronavirus and a resurgence of racial tension. With four months to go until the election, is staying in the basement Joe Biden’s best option? What are the risks if he does? And how could Donald Trump turn things around? Contributors: .

President Vladimir Putin has been in power for 20 years. The Russian people have been voting on a change to the constitution that could keep him in the Kremlin until 2036. While world leaders and opponents struggle to second guess him, some objectives appear to be clear: stability at home, respect abroad and power maintained for his inner circle.

Why is the movie business having trouble representing the world’s population on and behind the big screen? A rising share of the U.S. population are black, more than half of the demographic are female – so why is it so difficult to translate this into cinema? Hollywood has found itself red-faced in an era of Black Lives Matter and MeToo movements. From #OscarsSoWhite to criticism of who’s behind the films we see, the pressure to change is stacking up. Charmaine Cozier discovers the issues within the industry and what movie bosses prioritise over diversity. But will activists, actors and data be enough to convince big studios that the revolution is here – or will it just be business as usual?

From the bubonic plague and cholera to tuberculosis, pandemics have changed the ways cities have been designed and built. The coronavirus has been no different: with cities all over the world on lockdown, our cities have changed to become quieter, greener, with wildlife returning on an unprecedented scale. Now, with the lockdowns beginning to ease, Kavita Puri asks: what is the future of our cities? Will they return to the way they were - and do we want them to?

Ever since a mysterious virus was reported in December 2019 in the Chinese city of Wuhan, the world has been watching China. Silenced whistleblowers, unregulated wildlife trade in wet markets, limited international cooperation, and even a local biosafety lab have been held up as examples of how China mishandled the crisis. But how far can it be blamed for Covid-19 becoming a pandemic? This week on The Inquiry, Kavita Puri asks what the Chinese government could, or should, have done differently to prevent a global catastrophe.

To date, 7500 people have lost their lives in Germany in a population of 80 million. Other comparably sized European countries like the UK, France, Italy and Spain – some with smaller populations have deaths far exceeding Germany several times over.

In news reports and newspapers, pictures of British healthcare workers who have lost their lives to Covid-19 sit side by side. And if you look at those faces one thing stands out clearly. Of the 119 cases of NHS deaths more than two thirds are black or an ethnic minority - yet they only make up 20% of the workforce. Figures from the National Health Service in England show a disproportionate number of Covid-19 deaths are amongst these groups. And it’s not just in the UK. In the United States on available data – it’s a similar story with African Americans accounting for many more deaths in a community that make up 13% of the population. So what’s going on?

As some nations begin to tentatively lift their lockdowns, Tanya Beckett asks how best this can be done. What lessons, if any, can we learn from past pandemics? How do states make the decision, juggling the increasing demands of economic and social factors against public health concerns, amid worries of a new wave of infections from the disease? And what will our lives look like in a post-lockdown world? We hear from contributors based in France, the United States, South Korea and Denmark - one of the first countries to begin to lift its lockdown.

Last month, everyday supermarket items turned into valuable and vanishing commodities overnight – none more so than toilet paper. There are now billions of us around the world living in lockdown conditions, a situation we’ve not been prepared for. And we seem to be in this for the long haul. In this week’s Inquiry, we’ll be asking how we can help people stay rational in a pandemic.

How will Africa deal with Covid-19? It began in China then reached the Middle East, Europe and the United States, now Africa is bracing itself for a surge in coronavirus cases. But how will the continent, with its weaker health care systems and often poor populations cope? The picture is not the same everywhere. Some countries and some sections of society may fare better than others, but the worry is that many African countries simply don’t have the tools or resources to stand up to this pandemic. Or might there be some lessons learnt from the Ebola outbreak which could help? This is a continent of young people, so demographics could work in their favour, but many of them are already compromised by HIV, malaria and other disease outbreaks. Tanya Beckett speaks to the director of a hospital in rural Uganda, to the head of the Nigeria’s Centre for Disease Control, to the CEO of the Confederation of Zimbabwe Industries and to the former President of Liberia, Ellen Johnson Sirleaf, about their worries and preparations for Covid-19.

The race is on for the world’s scientists to develop a safe and effective Covid-19 vaccine. The Inquiry examines quickly how this can be done and what hurdles need to be overcome to roll out a vaccine in 12-18 months, rather than the many years it would normally take. Presented by Kavita Puri. (medical doctor with a vaccine. Credit: Getty images)

After China, South Korea was next in line to be struck by the Coronavirus outbreak. And in the early days the number of cases was going up fast – many of them related to a secretive religious sect. But the country has rapidly managed to get a grip on the outbreak and has kept its mortality rate low. It has done this without an official lockdown. The secret appears to be preparation, widespread testing and acting fast. With the help of four expert witnesses, Kavita Puri investigates what else we can learn from South Korea in its battle against Covid-19.

‘It’s a failing, let's admit it’ says top health official, Dr Anthony Fauci. He’s talking about the fact that it took a month for a working coronavirus test to be rolled out around the country, while other countries were testing thousands of people. How was this allowed to happen? In this edition of The Inquiry, we explore the ways in which the US lost valuable time in dealing with the coronavirus and how their health system could make things more difficult still.

There are now significantly more new cases of coronavirus outside China than inside. On the first day of this week there were only 44 new cases in the whole country. Just a few weeks ago that figure was in the thousands. While the authorities have been criticised for their initial slow response to the outbreak, allowing it to spread quickly, since January they have taken unprecedented action to clamp down on the spread of the virus. Whole cities have been put into quarantine and travel restrictions have been imposed on millions of people. New hospitals have been built with lightning speed and huge amounts of money has been spent on testing kits and other technology to fight Covid-19. China has been accused of infringing civil liberties in its fight against Coronavirus but it has also been praised for the extreme public health measures it has taken. So what did the Chinese actually do and can it be replicated elsewhere?

Climate change models have been a key tool to project what could happen with global warming in the future. But there’s a debate in the scientific community and some are saying too much emphasis has been put on the worst-case scenarios. Others argue that the impacts of climate change are too unpredictable and all scenarios, even the most serious, less likely ones, need to be kept on the table. All agree, though, that human-induced climate change is happening and that even the most likely projected temperature increases will be serious and potentially very damaging.

We have a great capacity to ignore facts and only believe what we want to believe – particularly if those facts clash with our convictions. Why is that and is it getting worse? It’s an area that is being intensely studied by psychologists, political scientists and neuroscientists. Ruth Alexander explores why we ignore facts, even if it’s bad for us. Though she also hears how, in some circumstances, it can be good for our mental health. But our casual attitude towards facts can have serious consequences. According to experts this is happening across the world, in politics, in health and in our daily lives. This behaviour is not the preserve of any particular political group – everyone does it when it suits them.

Britain is trying to make multiple trade deals since leaving the EU. Some negotiations between countries have lasted for years. The breakdown in the World Trade Organization, the changing nature and complexity of world trade and a general lack of trust between nations means it could be a very drawn out process. Presented by Tanya Beckett.

The Coronavirus outbreak in China has been declared a public health emergency of international concern. It is raising fears of a global disease pandemic. In the past viral infections have killed millions. Possibly the worst ever pandemic was the 1918-19 flu, which spread just as the First World War was coming to an end. Estimates of the death toll now range between 50 and 100 million. At the upper range that means it was more deadly than both World Wars put together. So could another pandemic emerge today and kill millions? How might it happen and how prepared are we to confront it? The world is a very different place to 100 years ago. Scientific and public health advances do mean some parts of the world are more prepared but our ways of living could make us more susceptible to a new virus. Speaking to a leading virologist, a disease modeller, a public health policy expert and a senior African health official, Ben Chu asks where the virus threat might come from, how fast it could spread, what containment policies work and whether the world is ready.

Could a new law in India be a step towards making Muslims second class citizens? The government says the Citizenship Amendment Act is a humanitarian law giving protection for people escaping religious persecution. But critics say that by excluding Muslims, the CAA contravenes the country’s secular constitution. Charmaine Cozier reports. (Women hold anti-government placards during a protest in Delhi.

How did Trump’s personality and way of dealing with people lead to a trial in the Senate? The answer involves Trump’s long standing belief in conspiracy theories, his transactional way of doing business, the revolving door of staff turnover at the White House and his admiration for Russian president Vladimir Putin.

On 25 July 2019, the President of the United States made a phone call to the recently-elected President of Ukraine - congratulating him on his party’s election victory. What Donald Trump said in that call to Volodymyr Zelensky has ended up threatening his own presidency, triggering the impeachment of the president. Donald Trump says his interest was in rooting out corruption. Meanwhile Joe Biden’s role in Ukraine was to do the same - root out corruption. The Inquiry asks why Ukraine has such a corruption problem. Presented by Ruth Alexander. (A Ukrainian flag flies in Independence Square in Kyiv, the capital of Ukraine.

President Trump’s decision to assassinate Qasem Soleimani came as a shock to America’s foes and allies alike. He was Iran’s top general and has been described as one of the country’s most powerful figures, second only to the Supreme Leader Ayotollah Ali Khamenei. He was, effectively, head of Iran’s foreign policy. He’s been credited as being instrumental in the fight against ISIS but has also been accused of arming and supporting terror groups. But why did Donald Trump order his death? Presenter: Tanya Beckett Producer: John Murphy (Image: Lieutenant General Qasem Soleimani / Photo handout from the Iranian Supreme Leader's office)

What is the chance of the human race surviving the 21st century? There are many dangers – climate change for example, or nuclear war, or a pandemic, or planet Earth being hit by a giant asteroid. Around the world a number of research centres have sprung up to investigate and mitigate what’s called existential risk. How precarious is our civilisation and what can be done to stop a global catastrophe? David Edmonds talks to four expert witnesses to try and find the answer. (Apocalyptic landscape.

Despite heroic efforts to vaccinate against this crippling disease, why does it persist? The fight to eradicate polio is an amazing story: It began with a grassroots movement in the United States and led to a global campaign to wipe out a disease that can cause paralysis and even death. There is no cure, but countless cases have been prevented by an extraordinary campaign to vaccinate every child aged five and under. It’s an operation that requires access to some of the poorest and most remote regions of the world. But polio was supposed to have been eliminated by the year 2000. Nearly two decades later, new cases are still springing up. Why? Neal Razzell examines the challenges and the triumphs in the effort to rid the world of polio.

Donald Trump is threatening to withdraw the US from Nato while the French President Emmanuel Macron has called it “brain dead”. Charmaine Cozier asks if the 70-year-alliance can survive?

Excluding dictators and royalty, there are around 2,000 people in the world who are billionaires. Some inherit wealth while others might build fortunes through inventions, businesses or investments. Some say individuals holding onto extreme amounts of money is wasteful because it could be diverted to other areas that would benefit more people such as education and healthcare. Others reason than some billionaires should keep what they have because they drive economic growth and inspire others to innovate. Are billionaires the right focus or should attention move to the systems and processes that enable them to make and keep huge amounts of money?

An estimated 2.6 billion people use social media, but in the online world not everything is what it seems. Fake accounts and automatic programmes can be used to spread disinformation and influence political narratives. We hear from experts across the world about how elections have been fought, and won, with the help of this electronic – and sometimes not so electronic – army. In a world where social media expansion shows no signs of slowing – how do we protect our elections from social media manipulators?

A year ago more than a quarter of a million people took to the streets across France, in what became known as the “gilets jaunes” protests. They began as a reaction to an increase in fuel tax - a tax which was supposed to help the environment, but which the protesters said meant they could no longer afford to drive their cars or get to work. These were the first high profile demonstrations against policies designed to tackle climate change, but they put a spotlight on a sense of unrest that has spread far beyond France. So if it is widely accepted that climate change is a real threat, why is there a backlash against climate policies?

If there was a serious illness that we knew thirty percent of us would experience in our lives, wouldn’t we do everything in our power to address it? Well research suggests that one in three of us will experience a serious mental health problem at some point in our lives; it’s a topic many are uncomfortable about discussing but one that shows no signs of going away. Slowly we’re beginning to learn more about which factors cause anxiety and depression but old prejudices are hard to come overcome so – what can we do about the world’s mental health problem?

In September 2019 violence broke out in the city of Johannesburg. Many people were beaten, at least 12 were killed, and shops were looted and burned down. The perpetrators were mainly poor black South African men, and those attacked were predominantly immigrants from other African countries and from Asia. This just the latest in a long line of xenophobic attacks in the country. In 2015 the army was even deployed to deter further unrest. Immigrants are often subject to threats on social media, and some have even voluntarily returned to their home countries in response. But in the country once labelled “the rainbow nation”, why are foreigners so often subject to violence?

This month activists all over the world have taken over city centres, demanding urgent action to halt climate change. They say we need to eliminate all carbon emissions by 2025. Most people think that’s impossible. But scientists are warning that if we want to stop global warming, we need to cut our CO2 emissions fast. So how soon can the planet achieve carbon zero? Helen Grady speaks to: Chukwumerije Okereke, professor in Environment and Development at Department of Geography and Environmental Science, University of Reading and director of the Centre for Climate Change and Development, Alex Ekwueme Federal University (AE-FUNAI), Ndufu-Alike, Ebonyi state, Nigeria; Mercedes Maroto-Valer, Director of the Research Centre for Carbon Solutions at Herriot Watt University in Edinburgh, Scotland; Roger Pielke Junior, Professor at the University of Colorado; Rachel Moncrief, deputy director at the International Council on Clean Transportation Producer: Beth Sagar-Fenton (Photo: Wind turbines in California USA.

Turkey’s push to clear the Kurds from its border with Syria has brought howls of betrayal. Many Kurds believed the Americans would protect them, after they’d defeated the so-called Islamic State terror group together. But this is just the latest of the dozens of conflicts in which the Kurds have been involved over the past few decades. Why can’t they find peace? Is it their fault? Should the regimes they live under take responsibility? Or does the blame lie further back in history?

After deaths in the US and bans around the world, how risky are e-cigarettes? In some countries, smokeless cigarettes are all the rage. In the UK, doctors say if smokers switch from tobacco to e-cigarettes, it will save lives. But in the US, where the authorities are investigating an outbreak of lung injury linked to vaping, they’re advising vapers to consider stopping. In India, Mexico and dozens of other countries, vaping is banned altogether. It’s a confused international picture. Vaping is still relatively new and scientists are still researching how harmful it may be in the long-term. What we do know is that every year, eight million people die worldwide as a consequence of smoking tobacco. What are the potential health risks associated with vaping? We’ll find out from our expert witnesses, who include a neuroscientist, a pulmonary critical care doctor and a professor of nicotine and tobacco studies.

The far right conspiracy theory featuring child molesters and baby eaters may sound far-fetched, but the FBI names Q Anon in a report warning conspiracy theorists pose a growing threat of violence. So can we dismiss Q Anon? Q releases anonymous internet posts and claims to have a high level of security clearance in the US, signing messages with only ‘Q’. The cryptic posts apparently reveal that Trump is fighting a battle against the deep state and trying to take on an A list paedophile ring. The followers decode the messages and enjoy feeling part of an online community who have ‘insider knowledge’. There’s no evidence behind any of it. The worrying thing is, it’s not just an online community, some followers have taken real world action, turning up in the desert with guns to hunt for satanic child molesters and a murder suspect has appeared in court with a letter Q written on his palm. Recently, the site Q posts on has been shut down, but our expert witnesses say that doesn’t mean we can dismiss Q Anon.

The world’s two biggest economies are fighting a trade war, European growth is slowing and global manufacturing data looks grim. Financial markets are flashing warning signs. It’s been a decade since the last global recession and in 2019 so far, the data has started to turn down. Are we on the verge of an economic meltdown? And what can countries do to avoid recession or reduce its impact when it comes? (A container ship being loaded in a harbour in Asia. Credit: Getty images)

It’s been almost 15 years since a successful campaign to erase the crushing debts of Africa’s poorest countries. Now, debt levels are again creeping up, thanks in part to a risky mix of easy credit and easy spending.

In the afternoon of August 20th this year, the sky over Brazil’s largest city, Sao Paulo turned dark. The cause of this premature night was the smoke from fires burning thousands of kilometres away in the Amazon rainforest. The scale of the fires caught the attention of the world, but the Amazon is one story among many. The global community has long worried about deforestation, five years ago nations agreed to work to halve global tree loss by 2020 and end it by 2030. This month, those targets were acknowledged to be missed. This week we investigate what tactics are being used to preserve forests around the world, and ask if any of them are effective. image: View of a burnt area of forest in Para state, Brazil, in the Amazon basin.

Bruce Springsteen is turning 70; rock’s gods are getting on. It’s not clear who’s there with electric guitars to replace them. Younger acts are failing to make hit singles. Veteran rock journalist Mark Coles believes rock music has lost its ability to surprise and innovate. Record label boss Vanessa Higgins describes how the writing of hit songs no longer favours the rock format. Music critic Michael Hann blames the high costs of making rock as part of the reason for its decline. But Chris Woltman, manager of the band Twenty One Pilots, believes bands have adapted rock for a new generation of fans and industry veteran Sat Bisla details how rock is making headway in non-traditional markets like India and Indonesia.

Quantum computers could transform our lives. Based on a branch of Physics that even Einstein found "spooky", the machines are still in their infancy. But governments and corporations are spending billions trying to turn them into workable technology. Neal Razzell finds out why by talking to four experts: Shohini Ghose, Professor of Physics and Computer Science at Wilfred Laurier University in Canada Stephanie Wehner, Professor in Quantum Information at Delft University of Technology in the Netherlands Winifried Hensinger, Professor or Quantum Technologies at the University of Sussex Jonathan Dowling, Professor of Theoretical Physics at the University of Louisiana and author of 'Quantum Technology - The Second Quantum Revolution' and 'Schrödinger's Killer App - Race to Build the World's First Quantum Computer'.

Fact-checkers say the President of the United States has made more than 10,000 false or misleading statements since coming to office. Whether it’s the size of the crowd at his inauguration, the pay rise offered to the military or where his father was born, Donald Trump often says things that are untrue. And he doesn’t rush to correct them, even when they’re outright fabrications. Ruth Alexander examines Donald Trump’s long record of falsehoods, which stretch back even to his schooldays. And she explores his motives, both political and psychological. Photo: US President Donald Trump addresses the press in the White House briefing room. Credit: Nicholas Kamm/Getty Images.

Porn, smart phones and the ‘slutty transmitter’. Adults in the US have sex on average about 50 times a year, which has dropped by 20 per cent over the last two decades. It’s a similar story in the UK, Australia, Germany, Finland and Japan. Could it be down to porn or our smart phones? Or is it actually down to something much harder to switch off? Some of the answers might surprise you. Picture: A couple in bed using their phones. Credit: Getty Images

It’s known for precision and punctuality but Europe’s engine is slowing down. Germany’s economy relies heavily on selling its products abroad. Famed for luxury cars like Porsche, BMW and Mercedes-Benz, exports are nearly half the German economy. So if countries decide they don’t want to buy, or can’t afford to buy, the things that Germany makes, it’s a problem. And that’s what’s been happening to Germany today. China – the most important market for most German car makers - is slowing down. Much of Europe is struggling and the US is pursuing its own protectionist policies, to get Americans to buy US-made goods. On top of that, the German car industry is facing tough new EU emissions tests (prompted by the Volkswagen emissions’ scandal of 2015), with crippling penalties if they don’t comply. So, buffeted by these adverse winds in part self-inflicted, in part beyond its control, the German government is being urged to boost its economy at home – by spending more on roads, bridges and broadband networks. But, as Neal Razzell discovers, despite having plenty of cash in the coffers, events in its past means Germany is reluctant to loosen the purse strings.

In 1965 a report from within the US government noted that the number of children born outside marriage, and the number of divorces, in the parts of the American population were rising rapidly. It argued that having many households run by a single woman risked holding back the progress of the next generation. At the time it was very controversial, rejected by mainstream academia and described as victim blaming. More than fifty years on, from the 'Moynihan' report we look at what modern research tells us about how children develop with married, cohabiting and single parents. Is there really a marked difference in their behaviour, cognition or emotional development?

Families from the Northern Triangle countries of Guatemala, Honduras and El Salvador now make up the majority of migrants arriving at the US southern border. Many from urban areas are fleeing endemic gang violence, while those from rural regions are affected by droughts and food security issues. The Mexican government is increasing security along their borders, while the Trump administration has been changing asylum law. Could these measures help to lower the number of people choosing to make the dangerous journey? Or is there another way to make sure migrants don't feel like they need to leave their homes?

Last month Hong Kong witnessed its largest ever protests, the most violent in decades. A proposed law to allow extradition of criminals to mainland China caused uproar. This bill exposed the cracks in relations between Hong Kong and the Beijing government. The current ‘one country, two systems’ arrangement gives the region some autonomy from Beijing. Pro-democracy protesters worry that this is being eroded as the Communist party is trying to bring it further under its influence. Complicating matters is Hong Kong’s significant but shrinking economic importance to China. With this year being the 30th anniversary of the Tiananmen square massacre the international community is nervously watching to see how modern China will respond to the civil disobedience on such a large scale.

With his unruly blond hair and shambolic appearance, Boris Johnson is Britain’s best-known politician. He’s also favourite to become the UK’s next Prime Minister. To his supporters, the former Mayor of London is charismatic, entertaining and a man of the people. His critics say he’s unprincipled, ruthless and flexible with the truth. If he wins the Conservative party leadership race, he’ll have to deliver Brexit. But what kind of leader might he be and how will he unite the country? Becky Milligan talks to some of those who’ve worked closely with him to find out what makes him tick.

South India’s biggest city, Chennai, is currently in the grip of drought. With the four main reservoirs which supply the city dry, residents have to queue for hours to collect pots of water from government tankers. Critics argue that the shortage isn’t just the result of a single failed monsoon season, but also the responsibility of the government who failed to plan for this scenario. Experts say 21 Indian cities could run out of groundwater next year, and that demand for drinkable water could outstrip supply by double in just a decade. So this week we ask, what can be done to solve this crisis? Image: Indian residents get water from a community well in Chennai Credit: Arun Sankar//AFP/Getty Images

Our species is facing a whole lot of problems. Antibiotic resistance is on the rise, land based minerals are depleting and there are serious concerns about how warm everything’s becoming. As the population grows these problems are only going to get worse, but what if we could find some of the solutions to our most pressing problems beneath the waves? Scientists have discovered that deep sea sponges could help fight MRSA, your smart phone could be powered by minerals located thousands of metres beneath the sea, and there are even enzymes that could help your washing machine run on a colder cycle, saving both energy and your new cashmere sweater. Is the deep sea the answer to some of our biggest problems? There’s a lot of promise, but what are the risks? Presenter: Ruth Alexander Producer: Lizzy McNeill (Photo: Sunset over the sea.

The Democratic Republic of the Congo is in the midst of an Ebola epidemic, with over 2,000 cases now confirmed. In June the virus spread to neighbouring Uganda.

Alabama has long been the butt of jokes in America. The stereotype is that it is backward, racist and right wing. This month the state passed one of the most restrictive laws on reproductive rights in the USA, banning abortion, even in cases of rape and incest. But it is not alone - many other states have similarly restrictive abortion laws but they do not get the attention that Alabama does. So why is it Alabama that always gets picked on?

Ever wanted to meet your historical heroes or explore the inventions of the future? Travelling in time has long been a dream of writers and filmmakers, but what does science tell us about how possible this would be to achieve in real life? We explore how physics shows us that time runs at different rates depending on where we are and how we’re moving - time goes more slowly for astronauts on the international space station for example. We hear about the very dangerous ways we could possibly exploit this to skip forwards through time and into Earth’s future, and we do the maths on wormholes, to see if they offer a possible portal to our past.

On 8 May 2018, the United States withdrew from the Joint Comprehensive Plan of Action - a nuclear deal between Iran, the US and other countries. Since then, tensions between Iran and the US have escalated to the point where some believe a conflict is imminent.

It's a multi-billion dollar industry, with bands selling out stadiums across the world. K-Pop, or Korean Pop has created some of the biggest global music stars. How did bands, singing in Korean come to such prominence? The Korean government has capitalised on the soft power that its music industry has offered. But with the latest scandals involving the rape and abuse of women is there a darker side to it all? And could it tarnish brand Korea?

After months of protests, the Sudanese president, Omar al-Bashir was removed from office on 11th April by a military coup. Initially there were celebrations, but weeks later, with no clear plan for the military to hand over power to a civilian government many in the country are starting to worry whether their victory has been lost. So is the country heading towards democracy or another autocratic regime? Photo: Sudanese protesters wave national flags near the military headquarters, Khartoum, April 2019.

The world’s population is set to grow from 7.7 to 11 billion by the end of this century. The challenge is to produce enough food to feed this number of people. In the 1960s the Green Revolution provided answers to similar problems – but the projected population growth of the future is on a much greater scale than before, and so new measures are required. In east Africa they’re working to reduce the amount of food that’s lost before it even gets to market – globally this stands at around 30 per cent. In the United States scientists are working to improve the natural process of photosynthesis – to make plants themselves function more efficiently. And in India they’re working to preserve genetic diversity – conserving rice varieties that can flourish in salt water or in conditions of drought.

Who benefits from our fear and is there more than just global reporting behind it? Has the world become more dangerous or has our perception of the world just changed? Rolling news and social media makes us aware of every threat no matter where in the world. From Ebola to flying we investigate the deeper reasons behind our modern fears. Speaking with experts in public health, risk and fear to find out why we are all so afraid.

In February a bomb blast killed at least 40 Indian paramilitary police officers in Kashmir; the worst attack by Pakistani militants in years. Indian military jets were deployed and one was shot down. As concerns over the pilot’s fate grew, fears mounted that India and Pakistan might go to war over Kashmir – again. The countries have been at war four times since partition in 1947. And Kashmir, which both countries claim in entirety but each one controls only in part, has been a key factor in the conflicts. But even when there is no war, there is no stable peace in Kashmir. Violent protests and street fighting are commonplace and daily life is made hard in numerous other ways. Unemployment is high, communication blackouts frequent and security fears constant. The Inquiry explores why the crisis has been so difficult to solve and what it might take for a resolution to emerge.

Life expectancy is going up as we develop new cures for the diseases that kill us off. But can we beat the most fatal condition of all - old age? We talk to scientists on the frontier of fighting the ageing process itself, when our bodies just start to wear out. In India, Tuhin Bhowmick is working towards 3D printing new organs so people don’t die waiting for transplants. In the US, Meng Wang is developing ways to use the tiny creatures that live in our guts to extend our lives. And in the UK, Lorna Harries and her team have made an amazing discovery that could let us roll back the ageing process in our own cells. But is there an upper limit to the human life span? With all these advances racing ahead we ask – how long can humans live?

Many nations have now entered the space race. China first sent a man into space in 2003 and in the last few months made a successful, unmanned, landing on the far side of the moon. This was a world first. India has its own record. A few years ago it launched more satellites into space, in one go, than any other nation. Nigeria is talking about sending an astronaut into space. And Kyrgyzstan is developing its first satellite, built entirely by female engineers. The Inquiry explores what lies behind all this activity. Is the power of national prestige giving way to different goals; education, economic progress and human rights?

In recent years, in trouble spots and war zones around the world – places such as Syria, Eastern Ukraine and Central African Republic – The Wagner Group has been active. They are fighters for hire. But very little else, for certain, is known about them. Are they mercenaries working for the Russian intelligence service? Or are they muscle men securing the financial interests of powerful oligarchs? The Inquiry traces the history of the group; why they emerged and how they operate now. It is a story that twists and turns and leads to surprising – and dangerous - places. Presenter: Kavita Puri Producer: Jordan Dunbar Picture Credit: Valentin SprinchakTASS via Getty Images

The European Union was formed in the years after the Second World War to secure peace and promote economic progress. It aimed to achieve that by ensuring that countries worked together. But that optimistic vision has now been shaken. There is mounting anxiety about whether the EU can hold together. Some are even saying that the EU is facing an existential crisis. That’s because the elections in May are likely to bring in another wave of populist politicians promoting nationalist agendas. The Inquiry will detail the fissures that have been exposed in recent years. One cause has been migration from countries outside the EU and the pressures caused by free movement within its borders. The severe economic downturn has threatened unity too. Kavita Puri explores whether there are moments in the European Union’s history when, had different decisions been made, the EU might have hung together better.

Driverless cars powered by renewable energy whisking their healthy and happy citizens between gleaming skyscrapers, criss-crossing efficient roads. That’s the dream of many so called smart cities. The trend for ‘smart cities’ has grown immensely over the last decade and their definition has evolved too. Hundreds are planned or are already being built around the world, in both rich and poor countries. From Google’s Sidewalk city to Eko Atlantic in Nigeria, tech companies are seeking to tame our ever more urban world. But critics worry that instead of being clever solutions they simply reinforce the existing poverty and inequality. How can a tech giant solve the problems of the developing world when people need water not wifi? We ask, are smart cities dumb?

Tens of thousands of children have been forced to join militia or terror groups in recent years. The Inquiry looks at conflicts around the world to find out what it takes to rehabilitate a child who has witnessed or taken part in violent extremism. We hear from experts who say it is as important to mend the community as much as the child. And we consider the position of stateless children, including those who have never been registered anywhere and those whose nationality is in dispute. If they end up belonging nowhere, can they ever recover? Presenter: Feranak Amidi Producer: Rosamund Jones Image: Children holding guns Credit: Mohammed Hamoud/Getty Images

Suicide is the second leading cause of death among 15-29 year olds globally. But innovative and unexpected ways to tackle this public health issue are emerging. From Nigeria to Finland, ordinary people and experts are putting their own experiences and expertise to use in coming up with ways that help prevent deaths in their communities. School timetables, video games and social media are among some of the new ways being trialled to cut deaths and break the taboo surrounding youth suicide. We ask what can be done to stop young people taking their own lives? Presenter: Kavita Puri Producer: Lucy Proctor (A young man watches the sunrise. Photo credit: Chalabala/ Getty Images)

Three million people in Yemen have been forced from their homes, and the dead are estimated to number many tens of thousands. But, compared to similar conflicts, global attention has been slight. The Inquiry asks why. It explores how the media has told the Yemeni story, and the impact valuable arms sales have had on international pressure – or the lack of it – to bring the conflict to an end. There are other factors too. The conflict in Yemen has created countless refugees, but they have not fled beyond the country’s borders. And Yemen’s divisive history has created a diaspora community that struggles to speak with one voice. What will it take to shine a brighter light on Yemen?

The tech giant has had a meteoric rise over the last ten years. It has overtaken Apple in the global smartphone market, and its equipment is in telecommunications systems in 170 countries worldwide. But Huawei now finds itself at the centre of a global scandal. Its chief financial officer - the daughter of the company’s founder - is under house arrest in Canada, accused of selling telecom equipment to Iran in contravention of US sanctions. A week later, a US court charged the whole company with bank fraud, obstruction of justice and theft of technology from rival T-Mobile. The company has been banned in New Zealand and Australia, and there are moves in the US to stop government employees from buying their products. Critics say if it wins the contracts for the new 5G network being created globally, it could give the Chinese government control over everything from smart phones, to cars, to pacemakers in other countries. So why has the success story soured? This week, we ask: what’s so scary about Huawei? Presenter: Kavita Puri Producer: Jordan Dunbar

More children than ever before attend school – so why have reading rates been so slow to improve? In some countries teachers are absent from class one day every week, in others early years education barely exists. And many children are taught to read in languages they do not speak. The Inquiry explores what reading skills get measured, and whether they are the right ones. And it asks how the quality of literacy education could best be improved.

In November 2018, a Chinese scientist stunned the world by announcing that he had successfully edited the genes of two embryos. These twins had their DNA changed to try and make them resistant to HIV, it was only successful in one. Shock and outrage followed as the media proclaimed that the age of the designer baby had arrived and we had opened a door that could never be closed. The Chinese government ordered an inquiry and the scientist rumoured to be put under house arrest. For many in the genetics community it had only been a matter of time until this happened. The game changer came in the form of a new technology known as CRISPR, a relatively simple and cheap way of changing genes. One that could be used in fertility clinics worldwide. Does this now mean an age of elite super humans could be born to the ultra-rich? Children created with superior traits, tall, beautiful and hyper intelligent. The truth is not so simple. This week we ask: should we fear ‘designer babies’? Producer: Jordan Dunbar Presenter: Michael Blastland (picture: foetus in utero /Getty images)

Ever since Donald Trump took office in 2016 his critics have been focussed on getting rid of him. As the Mueller probe into Russian collusion in the presidential election heads into its last six months, several members of President Trump’s inner circle have been convicted of serious crimes. For some, it’s only a matter of time before Trump himself is implicated. For others, the evidence so far is simply not substantial enough. With Democrats now in control of Congress, the votes are there to impeach Trump and send him for trial in the Senate. But what would it take to get the two thirds majority needed to remove him from office?

Human activity is sending animals and plants extinct. But there is a fightback going on. Scientists all over the world are coming up with radical solutions to save them - from transplanting polar bears, to “de-extincting” a very strange frog. And experts say each one of us can make a difference. So is it too late to save the planet, or can we stop a mass extinction?

This week we’re looking at nothing less than the state of life on earth. The planet has seen mass extinctions before, periods of widespread and dramatic species loss. Some now fear human activity is driving another one: land cleared for farms, homes and roads; waters filled with pollution and emptied of fish; skies choked with gasses causing climate change. But does it add up to a mass extinction? In the first of a two-part series, we examine the evidence of species loss and compare it with the geological record.

Millions of us take a vitamin tablet every day - how did they become so popular? We follow the rise and rise of vitamins from their discovery just a century ago, to the multi-billion dollar market of today. The story of how the vitamin supplement entered our daily lives takes us from the targeted guilt-tripping of concerned mothers, to the use of vitamins as a weapon against the Nazis, via a plan for vitamin doughnuts. Experts question whether most of us need to take them at all – so how did we get hooked on vitamins?

#MeToo became viral following allegations of sexual harassment and violence at the hands of Harvey Weinstein. Now women and men in their millions around the world have been mobilised by the hashtag to share their stories of abuse. But its founder Tarana Burke fears the movement has moved away from its original remit to give a voice to victims of sexual violence. She worries it is being talked about as a vindictive plot against men. So what is the reality on the ground around the globe? We hear about the impact of the #MeToo in India and Iran. What did it really achieve? Presenter: Kavita Puri Producer: Jim Frank (South Korean demonstrators at a rally for the country's #MeToo movement in Seoul, 2018.

Journalists have been subject to more killings, and increasing levels of violence and intimidation in 2018, according to monitoring groups. This year alone more than 30 have been murdered, including Mexican veteran journalist Carlos Domínguez Rodríguez who was stabbed to death in January, 5 journalists shot dead at their office in Annapolis in the US in June, and the story that has dominated the news, the murder of Saudi journalist Jamal Khashoggi at his consulate in Istanbul in October. The suspects range from organised criminals to state-sponsored assassins. And it’s not just about murder – imprisonments and intimidation are also on the rise. Why should the public care? What’s behind the surge? And how can the press and the public fight back? We talk to those journalists and activists from across the world to find out: is this the most dangerous time to be a journalist?

The UK voted to leave the European Union in June 2016. More than two years on, it’s still not clear how that will happen, or what will come after. Consensus within Westminster seems impossible, and if the deal currently on offer from Brussels is voted down on December 11, the UK could crash out of the EU with no deal at all. What makes it so hard to come up with a solution? The BBC has followed all of the twists and turns of the Brexit negotiations in minute detail. In this special programme, four correspondents from across the organisation give their take on what makes Brexit such a fraught process.

There’s talk of a new Cold War between Russia and the West. What responsibility does the West carry for the dismal state of relations? Russian leaders say Nato has expanded far beyond the borders that were agreed when the Soviet Union collapsed and a new European order was thrashed out. They see troops and hardware stationed close to their towns and cities as highly provocative. America and the EU are seen as meddling in the internal affairs of Russia and the states surrounding it by funding pro-democracy movements and helping to topple regimes. And a new arms race is underway. Russian military leaders perceive an active threat from the West – are they right? The previous edition was: Is Russia At War With The West? Presenter: Kavita Puri Producer: Lucy Proctor

There are currently a number of serious allegations made in the West against Russia. They include the attempted murder of the former spy Sergei Skripal on British soil; interference in the 2016 US election; the hacking of the American electricity grid. To some, it feels like the West is under attack. But do any of these actions amount to war? Olga Khovostunova, a Russian media analyst, describes the effect of the collapse of the Soviet Union on the psyche of President Putin and his close knit circle of security chiefs. For them, the threat from the West is real. Norwegian foreign correspondent Oystein Borgen says Russia is engaged in a hybrid war with the West, in which Norway has become a little-known front line. Lawyer Michael Schmitt, from the US Naval College, sets out how Russian security chiefs, almost certainly surrounded by a team of international law experts, operate in the grey zone of international law. Political scientist Kimberley Marten explains how private military contractors operating in Ukraine, Libya, the Central African Republic and Syria give the Russian state plausible deniability in conflict zones.

There are different routes to pariah status. North Korea, with its gross human rights abuses and illicit nuclear weapons programme tops the list and represents the classic pariah - completely ostracized from the international system. Another sure-fire way to become a pariah is to sponsor international terrorism, like Muammar Gaddafi’s Libya in the 20th century. But as his example shows, international rehabilitation can happen almost overnight. Then there are less clear cut pariahs like Zimbabwe, condemned by the West but very much part of the regional African system. Four expert witnesses examine these cases and explore whether the notion of a pariah state is meaningful in the 21st century multi-polar world.

Warnings about the approaching post-antibiotics apocalypse have been sounding for years. There are now strains of deadly bacteria that are resistant to all antibiotics. This means that doctors are faced with patients who have completely untreatable infections. Hundreds of thousands of people worldwide are dying due to antibiotic resistance - and this number is set to rise rapidly. If we carry on like this, scientists predict we will return to a pre-antibiotic era, where organ transplants, chemotherapy and C-sections are impossible. We have come a long way since 1928, when the famous chance discovery of penicillin led to a golden age in which antibiotics were seen as wonder drugs, heralding in an age of huge medical advances and increased human life spans. But by the 1990s we were running out of new antibiotics and infections were again a killer. How did this happen? Our expert witnesses are medic and historian, Dr Eric Sidebottom, Dr Scott Podolsky of Harvard Medical School, journalist Maryn McKenna and infectious disease specialist Brad Spellberg.

The burgeoning relationship between China and Africa has been one of the great economic stories of the 21st century. Billions of dollars of investment and loans from China have created radical change in many African countries. But not everyone is happy, with some even claiming this is a new form of colonialism. As signs of discontent grow in countries like Zambia, and investment numbers start to slip down, we ask: is the China-Africa love affair over?

Thousands died when an earthquake and tsunami struck Palu, Indonesia – but could more lives have been saved? Accusations have been made of a host of failings: alert systems that were out of action, sirens that didn’t sound, a government slow to give emergency help - even people who were too busy filming the disaster to run away. How much truth is there to this? Was everything done to warn people beforehand, and rescue people in the aftermath? We speak to experts on the ground and around the world to find out.

Most countries in the world have signed up to the idea that no child should work at all under a certain age – but is this the best approach? This week Nicolle, a 17 year old from Peru, has been part of a delegation of child labourers visiting the UN to ask them to rethink their ban on child labour. She’s been working since she was 8 years old, and says not only did her family need the money she earned, but working brought her status and respect. Some charities and experts working with child labourers agree that there are safe forms of child work. They say non-hazardous work can allow children to help their families, gain life skills, and even pay for the school uniforms and equipment they need to stay in education. But the UN and other former child labourers disagree, saying an outright ban is the only way to protect children from exploitation. We ask whether it’s time to rethink the ban on child labour.

DNA testing is big business. Millions of people worldwide are finding out about their ancestry and genetic health traits by sending off a spit sample to one of the big consumer genetic testing companies. But what do your genes really tell you? And could genetic testing have harmful consequences for our health and for society? Four experts chart the rise of consumer genetic testing and examine the claims made and our expectations about the results.

The story of how a line on a map becomes a hard state border that no one can cross. Korea was ruled as one Kingdom for a thousand years. They valued poetry and scholars helped rule the country. But their Kingdom was invaded by Japan. When Japan left, Russia and America raced to take their place. Amid frantic organising, a line dividing Korea in two was suggested. Who knew that line would become the front line in a war, eventually creating a hard border between two new countries? This is a special edition that 10-14 year olds can also enjoy, but if you are not in that age bracket we hope that there’s something in it for you too.

Ever since it began, women’s sport has been beset by a fundamental question: who gets to compete as a woman? It’s a debate which is more heated now than ever. That’s because in a few months, athletics’ governing body, the International Association of Athletics Federations, will introduce controversial new rules, regulating the participation of athletes with disorders of sexual development, commonly known as intersex conditions. It’s a debate that goes far beyond sport - throwing up difficult questions about what separates men from women. In this edition of The Inquiry we plunge into this debate, which is troubling women’s sport.

Thousands of cyberattacks occur every single day. Some hackers steal credit card details or pilfer money from online bank accounts. Others cripple businesses, or even governments. As tensions mount in cyberspace, what are countries doing to strengthen their cyber power and build a hacking army? In this Inquiry, we delve into some of the world’s most intriguing cyber operations – including Iran, Russia and North Korea. (Black Hat DEF CON cybersecurity conference in Las Vegas, Nevada USA.

It’s graduation day at the end of a religious summer school in Yemen’s Saada province. A class of young boys are off on a trip to a shrine. In a land of war, they are happy - jostling and full of energy on their school bus. Moments later, most of the boys are dead. A Saudi-led coalition airstrike has hit their bus. The bomb that was dropped by the Saudis was made in the United States, and Saudi Arabia is the America’s single biggest customer when it comes to buying arms. Critics argue that Donald Trump is quietly escalating America’s role in the Saudi-led war on Yemen, and many, including US Congress, have begun to question the relationship between the United States and Saudi Arabia. Will the US support Saudi Arabia no matter what? So on this week’s Inquiry we’re asking, who’s in the driving seat when it comes to the US – Saudi alliance?

The year 2030 was set by the UN as the world's deadline for halting the spread of HIV, stopping Aids deaths, and having the first generation since 1980 born and raised completely free from infection. But at last month’s 22nd International Aids conference the mood was less optimistic. Deaths from the disease, having stabilised, are now beginning to increase, with some people fearing the disease is now poised to add massively to its global death toll. As global funding for Aids decreases, and drug resistant strains of HIV rise, this week’s Inquiry asks, could we see another Aids pandemic?

It was May 2013 when Cody Wilson went public with his 3D-printed handgun. An online video showed the crude plastic object fixed on top of a tripod. The trigger was pulled from a distance by someone pulling a long piece of string. Since that first successful firing, 3D printed guns and the debate around them has come a long way. The design for Cody Wilson’s plastic firearm, dubbed the ‘Liberator’ has been downloaded from the internet nearly 100,000 times. The US government has tried to block its publication. But is the cat already out of the bag? Does the 3D printing revolution mean that people anywhere can print anything they want, as long as they get their hands on the right design? Can we control 3D printing? (image: A three dimensional (3D) printer creating a product / Shutterstock)

In India, false rumours about child kidnappers, spread on WhatsApp, have prompted fearful mobs to kill innocent people. In May 2018 a video went viral. The original, a Pakistani child safety video, had been edited to show two men on a motorbike driving up to a group of children playing cricket in the street. They swoop up a small boy in a red t-shirt and drive away. As the video spread across India people started receiving messages in their WhatsApp groups, some claiming to be from the local police, saying a gang of 250 to 300 people from outside their region had entered the area. It appealed to parents not to lose sight of their children. Rumours like this have led to the deaths of at least 18 innocent people across India over the last few months. But what is it about this simple messaging platform - one that a fifth of the planet use every single day - that breeds intimacy, fuels emotions, and spreads fear? This week on The Inquiry we ask: Is WhatsApp fuelling vigilantism and why? Image: A sign that says 'WhatsApp Neigbourhood Prevention'. Photo Copyright: Antal Guszlev

It’s a July morning in Ethiopia and Addisalem Hadigu, a journalist in his 50s, boards a flight to neighbouring Eritrea. But it’s no ordinary plane. This ‘bird of peace’ is the first commercial flight to operate between the two countries since 1998, and Addisalem is flying to see his wife and two daughters – the family he hasn’t seen in 20 years. Reunions like this are happening across Ethiopia and Eritrea, after the two countries finally agreed a peace deal and ended Africa’s longest war. But will it last? In this week’s Inquiry, we examine the ties that hold Eritrea and Ethiopia together, and the forces which could push them apart.

As relations with Iran and the West reach a new low point with the collapse earlier this year of the nuclear deal and the reintroduction of strict economic sanctions we ask: what does Iran think of the West? Pooneh Ghoddoosi explores a long and tortuous history of outside interference in the country. It dates back to the Western desire for Iran's rich oil reserves in the early 20th century, and continues through the CIA-backed coup in 1953, which strengthened the Shah's grip on the throne. The Western powers supported Saddam Hussein during the Iran-Iraq War, while the US is believed to have unleashed a highly effective cyber-weapon against the Iranian nuclear programme. Iran has reasons to be equally suspicious of Moscow - with the Russian Empire seizing large parts of historical Persia in the 19th century.

By the time she died at the age of 46, Koko the gorilla was a global superstar. Not only could she apparently understand two thousand words of spoken English and convey her own thoughts and feelings using sign language, but she was even able to give her own pet kitten a name. Some say that it’s impossible to know whether Koko really understood what she was communicating, or whether she was just trying to please people by signing certain things. Either way, her death raises questions about animals, and the ways in which we try to understand them. On this week’s Inquiry we examine how recent discoveries are bringing us closer to understanding our fellow creatures. We reveal some surprising animal capabilities, and ask whether we can ever know what it’s like to be anything other than human. image: European Hamster (Shutterstock)

Food production accounts for as much global greenhouse gas emissions as all forms of transport combined. That’s why many scientists think we can’t tackle climate change without addressing what we eat. So – in this week’s repeat Inquiry – we’re looking at alternative climate-friendly diets and asking what it would take to move the world towards them.

The world’s two biggest economies are on the brink of a costly standoff. The US has announced tariffs of 25% on a swathe of Chinese goods, starting July 6th. China has vowed to respond in kind. ‘If someone wants a trade war,’ China’s Commerce Minister said, ‘we will fight to the end.’ President Trump is bullish, threatening further tariffs and tweeting: ‘trade wars are good, and easy to win.’ But the WTO has warned that a trade war would have a ‘severe’ impact on the global economy. We look at the forces driving the conflict and how each side might back down. With Helen Grady. (Image: Cargo containers with USA and Chinese flags on their sides crashing together.

Donte Robinson and Rashon Nelson were waiting to meet a business associate in Starbucks. After two minutes, the store manager called the police and the African-American men were removed from the café in handcuffs. The Starbucks CEO has described the incident as “racial profiling”, claiming that the manager acted on unconscious racial bias. In response, he closed 8,000 branches of the coffee giant so his staff could attend anti-bias training. It’s not just Starbucks - diversity training, such as this, has become a multi-million dollar global business. On this week’s Inquiry, we examine why these biases are so ingrained and what we can do to eradicate them. (Photo: Two little boys on the grass. Credit: Shutterstock)

More than half the world’s countries are not producing enough babies to offset the number of deaths. Russia is the latest to experience a dip in the fertility rate, despite the government rolling out measures to encourage people to have more children. They have tried mortgage subsidies, giving couples days off to have sex, and rewarding fruitful mothers with the grand prize of a refrigerator. But the fertility rate continues to drop. It is a situation that governments in Spain, Singapore, Germany, South Korea and Japan all face. Many are calling this a demographic crisis, so this week we are asking how do you make people have babies?

Last year, the world watched as Islamic State was driven from Raqqa, the city they claimed as their capital. The UN has estimated that around 80% of the city’s buildings were destroyed or damaged in the battle. Eight months later, many Raqqans are returning home. Amid the rubble, life is slowly returning to Raqqa. This week, we investigate what life is like after Islamic State.

Chicago resident Robert McDaniel was surprised when a police commander showed up at his home to warn him that they were watching him. With only a misdemeanour conviction and arrests for a number of suspected minor offenses, he had somehow made it onto the Chicago Police Department’s so called ‘heat list’ - a list of names created by algorithm of those deemed to be most at risk of either being a victim or perpetrator of violent crime. In this Inquiry we look at whether computers can predict future of when, where and by whom crimes will be committed. Can analysing ‘big data’ help target scarce resources in more intelligent ways? Or are the algorithms exacerbating the already heightened tensions between police and the public? How effective are some of the ‘predictive policing’ systems already in use? The inner workings of many of these programmes are protected by private copyright laws too so how can you challenge the decision made by a secret algorithm?

Armenia's recent successful uprising is being celebrated as unprecedented for a former Soviet state. The so-called “velvet revolution” began on the last day in March with a protest walk. It ended two weeks and 100km later with the government overthrown. Yet revolutions rarely triumph. In this Inquiry we look at the factors that need to come together for such a revolution to succeed. Do they always need to be bloody and brutal or can non-violence resistance be as effective? How important are state institutions like the military to determining success? And what role do international relationships have to play? (Photo: Supporters of Armenian opposition leader Nikol Pashinyan celebrate at the central square of Yerevan, 2 May 2018.

Not long ago, they were calling each other names and raising fears of a nuclear war. Now, it is feasible they could together win the Nobel Peace Prize - if they can reach a deal. The mooted meeting between America’s Donald Trump and North Korea’s Kim Jong Un could go wrong in many ways. Mr Trump has already talked of walking out. But in a spirit of optimism, this week’s Inquiry hears from those who have brokered some of the world’s most unlikely pacts for advice on how to strike the deal of a lifetime. With Helena Merriman.

In late December 2017, one of the world’s leading neurobiologists died of pancreatic cancer. His name was Ben Barres. He was an extraordinary scientist, advancing our understanding of how the brain works, in particular how certain cells in the brain may contribute to degenerative brain diseases like Alzheimer’s and Parkinson’s. He had also lived the last 20 years of his life as a transgender man. He used his unique perspective of having ‘lived in the shoes of a woman and…the shoes of a man’ to become an outspoken opponent of gender bias. As the voice of the transgender community continues to grow in influence, what can wider society learn from people who’ve been in this rare position of living life as both a perceived man and woman? What does their experience tell us about the nature of gender bias? And does it help us fix it? (Photo: People hold a giant transgender flag at a gay parade. Credit: Bulent Kilic/AFP/Getty Images)

China’s ivory market is now closed for business. The country has long been one of the world's biggest consumers of ivory. But as of this year, buying and selling ivory in China is illegal. Carving factories, workshops and jewellers have all shut their doors. How did this happen? And will it be enough to save the African elephant?

When Robert Mugabe was deposed last year, he had ruled Zimbabwe for nearly four decades. How do dictators and authoritarians stay in power? James Tilley, a professor of politics at Oxford University in the UK, finds out what's in the dictators' survival guide. How do they control ordinary people and stop revolts? How do they stop rivals from taking over? And why are elections often helpful to securing their rule? Producer: Bob Howard.

The tide of public opinion is turning on plastic. The image of a whale with plastic stuck in its mouth on the BBC nature documentary Blue Planet 2 woke people up across the world to the reality of plastic pollution in our oceans. Experts think that by 2050, there could be more plastic than fish in the sea. Communities across the globe are saying that something must be done. But does this change in public mood spell disaster for plastic? And if so, what would replace it? We go from Europe, to the US and Indonesia to examine the supply and demand of plastic.

“Humans are the only species that willingly deprive themselves from sleep”. Ever since fire was discovered, we have traded off sleep time for other activities - from creating stone tools to partying. As our technology progressed, the list of things to do rather than sleep just got longer. But with sleep deprivation now a growing health problem, could we be reaching our limits? Or is tiredness part of our condition? In this week’s programme, an evolutionary biologist, a historian and a neuroscientist give us their take on whether we are now any more tired than our ancestors. We hear what makes human sleep unique and how it has evolved in surprising ways. And finally we hear from a woman with a dream – that we may never have to sleep again. Presenter: James Fletcher Producer: Estelle Doyle and Sarah Shebbeare This programme was first broadcast in July 2017. (Photo: A woman shows signs of tiredness as she counts ballot cards.

From courtrooms and prisons to rehab centres and martial arts training. We look to Europe, Iraq, Central Asia and Saudi Arabia to investigate how they are dealing with Islamic State militants. The defeat of Islamic State in Iraq and Syria has raised a new, global challenge. While Iraq is funnelling huge numbers of Islamic State suspects through its courts, thousands of foreign fighters are returning to their home countries. What is happening to former IS fighters?

It is one of the largest, most profitable companies in the world, with billions of users, but more and more questions are being asked of Facebook. Accused of allowing the spread of fake news and hate speech, and of turning a blind eye to election meddling by Russia, Facebook is in the spotlight for the wrong reasons. Facebook’s founder and CEO, Mark Zuckerberg has committed himself to “fixing Facebook.” With the help of experts in the field, in the US, India and Germany, we ask if Facebook really is in trouble.

The US and UK governments have accused Russia of orchestrating the most damaging cyber-attack in history. It caused billions of dollars’ worth of damage in over 60 countries. This programme tells the story of the attack as it unfolded across the globe. With the help of the world’s leading cyber security experts we take a forensic look at how the attack began, the extraordinary way in which it spread, and examine the international repercussions.

Women earn less than men in every country in the world. Women are now more educated than ever before. But, on average, they don't take home the same in their pay packets. And laws against discrimination in the workplace haven't been enough to close the gap. This inequality in wages has proven difficult to shift. Governments, employers and unions are struggling to find solutions to this stubborn and deep-rooted problem. How do you close the gender pay gap?

It is feared than in a few months’ time Cape Town could run out of water. The city is planning for so-called Day Zero when the supply is switched off and people will have to collect water rations. Cape Town is an extreme example of what is now a global phenomenon of water scarcity. We investigate how the city got so close to the brink, and whether there’s anything that other cities around the world can do to avoid a similar fate. (image: A man collects drinking water from taps that are fed by a spring in Newlands,Cape Town at the foot of Table Mountain. Photo credit: Rodger Bosch/Getty Images.)

The Taliban have staged devastating attacks in the capital of Afghanistan, Kabul, in recent weeks. And a BBC study has discovered the group is active across the majority of the country – pushing beyond its traditional southern stronghold into eastern, western and northern parts. Seventeen years after the Taliban were toppled by a US-led invasion, it is clear the insurgent group has not been defeated. Why are the Taliban so resilient? Presenter: Helena Merriman Producers: Ruth Alexander and Josephine Casserly

The story of how the search for a material to replace ivory changed our lives forever. In the 19th century a billiard ball company placed an advert in a newspaper offering $10,000 to anyone who could come up with a substitute for ivory. There was growing concern that companies were hunting elephants into extinction so they could use their ivory for billiard balls, buttons and umbrella handles. The story that follows takes us from explosive factories that often went up in smoke to the modern world we find ourselves in today. How did plastics go from being a saviour of the environment to a cause for concern? How did we get hooked on plastic?

China has long been keen to assert its authority in the South China Sea. In recent years, it has undertaken a huge programme of island-building to stake its claim to the region. Fiery Cross, once a tiny reef, is now a fortified airbase. And this is just one of China’s seven artificial islands in the Sea. But China is not the only one. Bordered by seven states, many others also claim parts of the South China Sea as their own. Experts warn these hotly contested waters could be a flashpoint for conflict in 2018. Why is the South China Sea so important to China? (Photo: Fiery Cross. Credit: CSIS Asia Maritime Transparency Initiative/DigitalGlobe)

The EU’s launched the ‘nuclear option’ against Poland, the first time it’s triggered the disciplinary measure in its history. They say recent changes to the legal system mean there is a serious threat to the rule of law and as a punishment, Poland could lose its voting rights in the European Union. The ruling party say this is an attack on Poland and that the EU should not be telling them what to do. The government says that actually their judiciary is threatened by the legacy of communism which is why they have made the legal reforms. They also say they’re being singled out by the EU for their refusal to take refugees, which they claim pose a threat to their country. If you believe the government, there are lots of threats to Poland, but what is actually being threatened and is there something far greater at stake? What is the greatest threat to Poland?

In 2017 the black flag of the Islamic State group flew in the southern Philippines as a mixture of local and foreign fighters attacked the Islamic City of Marawi. While the government did eventually regain control, it took five months to break the siege and many terrorist leaders escaped during the fighting. It's led to fears that the extremist violence could spread. In this Inquiry we investigate the long history of conflict which provided a fertile place for IS's Islamist ideas to grow, and ask how important the region is to IS now that they're retreating in the Middle East.

In 1994 a United Nations conference, backed by 173 countries, announced that ‘female genital mutilation’ was a “violation of basic rights and a major lifelong risk to women’s health”. Agreeing it should end, international agencies and charities quickly swung into action, and over the next two decades millions were spent on campaigns to eradicate the practise around the world. Today though, pricking or cutting of the genitalia still happens to an estimated 3 million girls a year in 30 countries, and some experts are saying we should rethink how we tackle it. In this episode of The Inquiry we talk to four expert witnesses, all with very different views on what the next steps should be. This programme contains frank discussions of a physical and sexual nature. (Image: A demonstration against female genital mutilation at the Nairobi World Social Forum in Nairobi, Kenya.

Making sense of the digital currency and the ideology of its founders, fans and future. In 2010 a developer spent 10,000 bitcoin to buy two pizzas. Seven and a half years later that was the equivalent of over $80m. Bitcoin has been exploding in value throughout 2017 as more and more people buy into the idea of a digital currency. Traditional financial institutions have even begun to get involved. But far from a mainstream investment, Bitcoin started life as an idea from the radical cypherpunk movement, who wanted to use decentralised technologies as a way to disrupt governments and corporations. In this edition of The Inquiry we trace the history and development of Bitcoin – and ask whether its future will stay true to its libertarian roots. (Image: The Digital Cryptocurrency Bitcoin.

What next for North Korea? Kim Jong-un's nuclear ambitions and their global repercussions are explored in this special, extended edition of the programme. After a year of repeated weapons testing by the secretive regime that’s sparked a war of words with the United States, Ruth Alexander brings together six expert witnesses to dive deep into the detail of what is one of the biggest geopolitical challenges of our time. Their discussion examines North Korea’s weapons capability, the mind-set of its leader, the chance of war breaking out and the possibilities of finding a diplomatic solution.

Governing moon miners, asteroid hunters and space junk sounds pretty tricky, but we better get our act together. This year the majority of space launches included commercial enterprises. Space is no longer just the playground of governments but companies; companies that want to mine the moon for water that they could sell as rocket fuel, companies that want to mine the moon for helium -3 which could be sold and used as energy back on earth and companies that want to mine asteroids for platinum that they could sell for huge profits. But is this legal? The Outer Space Treaty, a set of laws written in the 1960s, says no state can conquer or own the moon or any other celestial body. So if you can’t own the moon, can you sell what you find on it? Perhaps it’s time for a new set of laws. So, how do we rule the universe?

There is a place on the internet where almost two billion of us regularly go – many of us, every day. Facebook: the social network which Mark Zuckerberg started in his university dorm room and which has grown, in a little over a decade, into one of the most valuable companies in the world. But what does Facebook’s lines of computer code do with the data we give it – and what could it do in the future? Just how powerful is Facebook's algorithm? The answer will surprise you. Produced by Estelle Doyle and Sarah Shebbeare This programme was first broadcast in April 2017.

Forty-two Americans die every day from an overdose involving painkilling prescription opioids. President Donald Trump recently declared the US opioid epidemic a national public health emergency. Yet in the world’s poorest countries, cancer patients and people recovering from major surgery often get no effective pain relief at all. Why is access to prescription painkillers so unequal? And is the shortage of opioids in much of the world getting the attention it deserves? (Photo: View of poppies in a poppy field in the state of Guerrero, Mexico. Credit: Pedro Pardo/Getty Images)

Missiles, fighter jets and mines waiting on the sea bed - war games in the gulf. Tension between Iran and Saudi Arabia is at an unprecedented level since a missile was intercepted over Saudi Arabia’s capital city. The Saudi Crown Prince blames Iran and says the attack may be considered an act of war. This is what would happen if they did go to war. (Photo: An Iranian missile is test-launched during war games in Qom, south of Tehran. Credit: Shaigan/Getty Images)

The world’s most profitable company is accused of aggressively dodging tax. Leaked documents in the Paradise Papers show Apple moved hundreds of billions of dollars in untaxed foreign profits to Jersey, where foreign companies pay no corporation tax. Yet Apple says it pays “every dollar it owes in every country around the world”. Confused? Not for long. (Customers wait in front of the giant Apple logo for the store to open in Munich, Germany.

He’s pushed through reforms but some fear there is a darker desire driving the ruler. In one night, Crown Prince Mohammad bin Salman arrested over a dozen Princes and government ministers on corruption charges. To turn on his own royal family, he must be serious. But is corruption the Crown Prince’s real target or is this a power grab? There are also fears that the aggressive stance he has taken with Lebanon, Yemen and Qatar is increasing tensions with regional rival Iran. If the tension reaches a tipping point, there are fears the conflict could widen beyond the region. So what is he up to? What does the Saudi Crown Prince want?

Academic research stands accused of turning a blind eye to dodgy data, failing to reconcile contradictory findings and valuing money over knowledge. We examine the criticisms, which go the very heart of our pursuit of knowledge. (Photo: Scientist working in a research laboratory. Credit: Shutterstock)
