The ocean is the largest region of the planet and remains a source of newly discovered species. But what do you do with a treasure trove of new viruses? A research team wrote in Science last month about finding thousands of new RNA viruses, and five new taxonomic phyla, in water samples from around the globe.
The new species more than doubles the known number of RNA viruses on the planet, painting a clearer picture of the vast abundance and diversity of viruses in ocean ecosystems. Though they may be small, research on DNA viruses in the ocean has previously suggested tiny viruses may have a role in something as large as the global carbon cycle.

How Recreational Weed Transformed A Small California Town
From the outside, Jose Rivas’s gray, one-story office building seems just as unassuming as Woodlake, the small Tulare County City where it’s located. But once you’ve been escorted inside the wrought iron gate and checked in at the security desk, you’ll see a chemistry lab of so many potheads’ dreams: bubbling evaporators, storage tanks of liquid nitrogen, and trays and trays of drying marijuana buds.
But Rivas isn’t a pothead – he’s the CEO of a cannabis company known as Premium Extracts that squeezes, distills and steams everything it can from the flower. “Essentially what we’ve developed here is a methodology to isolate the components and molecules of the cannabis plant, which are responsible for its taste, its flavor, and all the nuanced aroma that comes from each individual cannabis strain,” Rivas said.
Meet The Doctor Trying To Bring Medical Marijuana Into The Mainstream
An increasing number of states in the U.S. are legalizing medical cannabis, which means millions of people have access to medical marijuana cards. These can be used to buy cannabis to manage pain, treat mental health conditions, and help sleep issues.
But a majority of U.S. medical schools offer no education about medical marijuana and its effects on the body. As a result, many physicians and medical professionals do not feel knowledgeable enough about cannabis to make recommendations to patients about what their options are: With so many methods of taking marijuana, and an endless combination of dosages and strains, many patients and doctors feel at a loss.
Dr. Mikhail Kogan is trying to change that. As the medical director for the George Washington University Center for Integrative Medicine in Washington, D.C., Dr. Kogan is one of the foremost experts on using medical cannabis to treat a variety of conditions. A majority of his patients are geriatric and suffer from conditions as wide-ranging as cancer and Alzheimer’s. Dr. Kogan traces his experience using marijuana as an alternative medicine in his book, Medical Marijuana: Dr. Kogan’s Evidence-Based Guide to the Health Benefits of Cannabis and CBD.
Ira chats with Dr. Kogan about why marijuana is successful as a treatment for so many medical conditions, and how interested patients should approach their physicians if they feel it could be right for them.
The World According to Sound: Listening to WiFi
When you walk down a city street, you may not know it, but you’re being bombarded with WiFi data streaming from people’s home routers, phones, and businesses.
Frank Swain and Daniel Jones recorded the WiFi signals while walking down a few streets in London. They used smartphones to capture the data and turn it into sounds. It’s like a geiger counter, but for WiFi instead of radiation. Faster clicks mean higher wifi signal strength, robotic beeps are the router ID numbers. They call this project “Phantom Terrains.” They want us to consider how much of our urban world is saturated by invisible streams of data.
Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
