News stories on using pets in clinical trials to test veterinarian drugs, debunking the Piltdown Man once and for all, and deciding just how smart crows can be, with David Grimm.


From the magazine

It’s really difficult to figure out how old a free-living animal is. Maybe you can find growth rings in bone or other calcified body parts, but in sharks like the Greenland shark, no such hardened parts exist. Using two different radiocarbon dating approaches, Julius Neilsen and colleagues discovered that the giant Greenland shark may live as long as 400 years.

News stories on bees that live perilously close to the mouth of a volcano, diagnosing arthritis in dinosaur bones, and the evolution of the female orgasm, with David Grimm.

 From the magazine

Rivers deliver water to the ocean but water is also discharged along the coast in a much more diffuse way. This “submarine groundwater discharge” carries dissolved chemicals out to sea. But the underground nature of these outflows makes them difficult to quantify.  Audrey Sawyer talks with Sarah Crespi about the scale of this discharge and how it affects coastal waters surrounding the United States.

Stories on birds that guide people to honey, genes left over from the last universal common ancestor, and what the nose knows about antibiotics, with Devi Shastri.

 The Endangered Species Act—a 1973 U.S. law designed to protect animals in the country from extinction—may need a fresh look. The focus on “species” is the problem. This has become especially clear when it comes to wolves—recent genetic information has led to government agencies moving to delist the grey wolf. Robert Wayne helps untangle the wolf family tree and talks us through how a better understanding of wolf genetics may trouble their protected status.

Stories on a lichen threesome, tremors caused by tides, and a theoretical way to inspect nuclear warheads without looking too closely at them, with Catherine Matacic.


Despite concerns about antibiotic resistance, it seems like antimicrobials have crept into everything—from hand soap to toothpaste, and even fabrics. What does the ubiquitous presence of these compounds mean for our microbiomes? Alyson Yee talks with host Sarah Crespi about one antimicrobial in particular—triclosan—which has been partially banned in the European Union.

Listen to stories on how once we lose cartilage it’s gone forever, genetically engineering a supersniffing mouse, and building an artificial animal from silicon and heart cells, with Online News Editor David Grimm.

 As we learn more and more about exoplanets, we find we know less and less about what were thought of as the basics: why planets are where they are in relation to their stars and how they formed. Kevin Wagner joins host Sarah Crespi to talk about the latest unexpected exoplanet—a young jovian planet in a three-star system.
