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.
