When people are sick, we seek out medications and treatments to help heal. For a long time, scientists thought that was a uniquely human ability. But it turns out, many other animals do a version of it too! And since the late 1980s, western researchers have been trying to get a peek behind the curtain. And aside from just cataloguing all the cool examples just to know, there’s a real hope that studying animals’ medical cabinets may be the most promising way to expand our own. We get into the weeds with freelance science journalist Mandy Nguyen.

Hurricane season is upon us and it turns out that these powerful storms can quickly affect the biology of animals. After hurricanes Irma and Maria hit the islands that make up Turks and Caicos about a decade ago, the silver key anole adapted. They now have a shorter fourth toe on their hind legs! That could help them cling to objects better. But how do you know unless you put lizards in front of a fan and record how long they can hold on?

This study is out now in the journal Current Biology.

Summer is winding down and school is back. And all of that has us thinking about this idea that something happens in the human brain when we turn 25. Suddenly, we can rent a car without fees. Make rational decisions. We may even regret some of our past… indiscretions. All because we’re developed…right? Well, a paper in the journal Nature suggests that may not be the case. Neuroscientists found four distinct turning points in brain development across the human lifespan – and that the brain may be in its “adolescent” phase until about the age of 32. (Encore episode)

Hot weather isn’t just an inconvenience. It’s killing thousands more Americans than show up in official records. That’s the finding from a new NPR investigation, in partnership with Boston University. And the way they came up with that new, better estimate of the true toll of heat is, of course, with science. This episode, we’ll bring you all the details – and chat about why getting good estimates could save lives.
