Kleptotherms

from Radiolab · host WNYC Studios

In this episode, we break the thermometer and watch the mercury spill out as we discover that temperature is far stranger than it seems. We first ran this episode in 2021: Five stories that run the gamut from snakes to stars. We start out underwater, with a species of snake that has evolved a devious trick for keeping warm. Then we hear the tale of a young man whose seemingly simple method of warming up might be the very thing making him cold. And Senior Correspondent Molly Webster blows the lid off the idea that 98.6 degrees Fahrenheit is a sound marker of health.

Pickle WNYC Studios Is it ever okay to tell a lie? What makes a real friend? And here’s a question: How much is a person’s life worth? Yikes, that’s a tough one! Join the cast of Pickle as we explore life’s stickiest wickets, with the help of curious kids – and the occasional elephant. It’s philosophy, made fun. WNYC Studios is a listener-supported producer of podcasts including Radiolab, Snap Judgment, On the Media, Death, Sex & Money and many others.© WNYC Studios The Other Latif WNYC Studios Radiolab reporter Latif Nasser always believed his name was uniquely his own. Until he makes a shocking discovery that he shares his name with another man: Detainee 244 at Guantanamo Bay. The U.S. government paints a terrifying picture of The Other Latif as Al-Qaeda’s top explosives expert, and an advisor to Osama bin Laden. Nasser’s lawyer claims that he was at the wrong place at the wrong time, and that he was never even in Al-Qaeda. This clash leads Radiolab’s Latif into a years-long investigation, trying to uncover what this man actually did or didn’t do. Along the way, Radiolab’s Latif reflects on American values and his own religious past, and wonders how his namesake, a fellow nerdy, suburban Muslim kid, traveled such a strikingly different path. Note to Self WNYC Studios Is your phone watching you? Can texting make you smarter? Are your kids real?

You don’t have to be a kid to listen, just someone who likes to see the world anew.You’ll hear a range of nature stories on this podcast. Sometimes these will be brand new Terrestrials episodes, full of original songs (by “The Songbud” Alan Goffinski) that tell a fantastical-sounding story about nature that is 100% true. Sometimes these will be our very best, shiniest, furriest, leafiest Radiolab episodes about animals or plants or nature. The stories that drop here will always be family-friendly and safe for kids.
