Radiolab

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.

One spring evening in 2024, science journalist Rachel Gross bombed at karaoke. The culprit was a bleed in a fist-sized clump of neurons tucked down in the back and bottom of her brain called the Cerebellum. A couple weeks later, her doctors took a piece of it out, assuring her it just did basic motor control - she might be a bit clumsy for a while, but she’d still be herself. But after that surgery Rachel did not feel quite like herself. So she dove into the dusty basement of the brain (and brain science)  to figure out why. What Rachel found was a new frontier in neuroscience. We learn what singing Shakira on stage has to do with reaching for a cup of coffee  — and why the surprising relationship between those two things means we may need to rethink what we think about thinking.

A man on a mission to make a movement to make you feel better about yourself … and, in so doing, maybe change the world. Most of us spend some part of our lives feeling bad about ourselves and wanting to feel better. But this preoccupation is a surprisingly new one in the history of the world, and can largely be traced back to one man: a rumpled, convertible-driving California state representative named John Vasconcellos who helped spark a movement that took over schools, board rooms, and social-service offices across America in the 1990s. This week, we look at the rise and fall of the self-esteem movement and ask: is it possible to raise your self-esteem? And is trying to do so even a good idea?

This episode, first aired in 2019, brings you the story of John Scott, the professional hockey player that every fan loved to hate.  A tough guy. A brawler. A goon. But when an impish pundit named Puck Daddy called on fans to vote for Scott to play alongside the world’s greatest players in the NHL All-Star Game, Scott found himself facing off against fans, commentators, and the powers that be.  Was this the realization of Scott’s childhood dreams? Or a nightmarish prank gone too far? Today on Radiolab, a goof on a goon turns into a parable of the agony and the ecstasy of the internet, and democracy in the age of Boaty McBoatface. Special thanks to Larry Lynch and Morgan Springer.

A year ago we brought you a show called Shell Game where a journalist named Evan Ratliff made an AI copy of himself. Now on season 2 of the show, Evan’s using AI to do more than just mimic himself — he’s starting a company staffed entirely by AI agents, and making a podcast about the experience. The show is a smart, funny, and truly bizarre look at what AI can do—and what it can’t. This week we bring you the first episode of Shell Game Season Two, Minimum Viable Company. You can sign up to get the rest of the Shell Game ad-free, and the Shell Game newsletter, at shellgame.co . EPISODE CREDITS: Shell Game Hosted by Evan Ratliff, Produced and edited by Sophie Bridges.

Qasem Waleed is a 28-year-old physicist who has lived in Gaza his whole life. In 2024, he joined a chorus of Palestinians sharing videos and pictures and writing about the chaos and violence they were living through, as Israel’s military bombardment devastated their lives. But Qasem was trying to describe his reality through the lens of the most notoriously confusing and inscrutable field of science ever, quantum mechanics. We talked to him, from a cafe near the Al-Mawasi section of Gaza, to find out why. And over the course of several conversations, he told us how this reality-breaking corner of science has helped him survive. And how such unspeakable violence actually let him understand, in a visceral way, quantum mechanics’ most counter-intuitive ideas.

When we think of China today, we think of a technological superpower. From Huawei and 5G to TikTok and viral social media, China is stride for stride with the United States in the world of computing. However, China’s technological renaissance almost didn’t happen. And for one very basic reason: the Chinese language, with its 70,000 plus characters, couldn’t fit on a keyboard. Today, we tell the story of Professor Wang Yongmin, a hard-headed computer programmer who solved this puzzle and laid the foundation for the China we know today. Special thanks to Martin Howard.

This is the story of a three-year-old girl and the highest court in the land. The Supreme Court case Adoptive Couple v. Baby Girl is a legal battle that has entangled a biological father, a heart-broken couple, and the tragic history of Native American children taken from their families. We originally released this story back in 2013, when that girl’s fate was still in the balance of various legal decisions. We thought now was a good time to bring the story back, because the Act at the center of the story is still being questioned. When then-producer Tim Howard first read about this case, it struck him as a sad but seemingly straightforward custody dispute. But, as he started talking to lawyers and historians and the families involved in the case, it became clear that it was much more than that. Because Adoptive Couple v. Baby Girl challenges parts of the 1978 Indian Child Welfare Act, this case puts one little girl at the center of a storm of legal intricacies, Native American tribal culture, and heart-wrenching personal stakes.
