  • The genetic secret helping bats survive a deadly epidemic

    The genetic secret helping bats survive a deadly epidemic
    Oct 5 2026
    We’re easing you into Halloween season with an episode about bats. There’s a silent serial killer decimating little brown bats as they hibernate. White nose syndrome has driven populations across the U.S. to almost the brink of extinction over the last decade. But recently, conservation biologist Giorgia Auteri and her team noticed several genetic mutations in the survivors. These mutations could explain how natural selection has shifted the existing population – and inform conservation efforts in the future.

    Oct 2 2026
    Being more social has a ton of benefits: lower stress, decreased inflammation – even living a longer life! Recently, some scientists have added lowering your blood sugar to the list. To figure it out, researchers had people break bread both in duos and alone. And they think the results could tell us something about the roots of our social nature. Consider it another reason to prioritize our social lives.

  • How much of Earth's life is still undiscovered?

    How much of Earth's life is still undiscovered?
    Sep 30 2026
    If you, like us, clicked on the cute cat photos posted everywhere recently, announcing the discovery of the first new cat species in more than a century, you might have wondered how rare it is to find a new species. Turns out, it’s not! We live in an era of “unprecedented” discovery, says John Wiens, a professor of ecology and evolutionary biology at the University of Arizona. And scientists say we’re still just scratching at the surface of how much life exists on Earth.
