Radiolab

Summer 2023 was a pretty scary one for the planet. Global temperatures in June and July reached record highs. And over in the North Atlantic Sea, the water temperature spiked to off-the-chart levels. Some people figured that meant we were about to go over the edge, doomsday...

Most of us would sacrifice one person to save five. It’s a pretty straightforward bit of moral math. But if we have to actually kill that person ourselves, the math gets fuzzy. That’s the lesson of the classic Trolley Problem, a moral puzzle that fried our brains in an episode we did almost 20 years ago, then updated again in 2017. Historically, the questions posed by The Trolley Problem are great for thought experimentation and conversations at a certain kind of cocktail party...

Today, the story of an idea. An idea that some people need, others reject, and one that will, ultimately, be hard to let go of...

In this episode from 2007, we take you on a tour of language, music, and the properties of sound. We look at what sound does to our bodies, our brains, our feelings… and we go back to the reason we at Radiolab tell you stories the way we do.  First, we look at Diana Deutsch’s work on language and music, and how certain languages seem to promote musicality in humans. Then we meet Psychologist Anne Fernald and listen to parents as they talk to their babies across languages and cultures...

A couple years ago, our producer Annie McEwen listened to an audio documentary that, she said, “tore my heart wide open.” That episode , “Finn and the Bell,” (https://zpr.io/TDjwQuXFDSz6) by independent producer Erica Heilman (maker of the podcast  Rumble Strip), went on to win some of the biggest awards in audio (including a Peabody, https://zpr.io/tu4hwhKQ3TWN), and the rest of the staff finally got around to listening, and it tore our hearts wide open, too...

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...

Matthew Herrick was sitting on his stoop in Harlem when something weird happened. Then, it happened again. And again. It happened so many times that it became an absolute nightmare—a nightmare that haunted his life daily and flipped it completely upside down. What stood between Matthew and help were 26 little words. These 26 words, known as Section 230, are the core of an Internet law that coats the tech industry in Teflon...

In online news, stories live forever. The tipsy photograph of you at the college football game? It’s there. That news article about the political rally you were marching at? It’s there. A charge for driving under the influence? That’s there, too. But what if... it wasn’t? Several years ago a group of journalists in Cleveland, Ohio, tried an experiment that had the potential to turn things upside down: they started unpublishing content they’d already published...

In 1908, on a sunny, clear, quiet morning in Siberia, witnesses recall seeing a blinding light streak across the sky, and then… the earth shook, a forest was flattened, fish were thrown from streams, and roofs were blown off houses. The “Tunguska event,” as it came to be known, was one of the largest extraterrestrial impact events in Earth’s history. But what kind of impact—what exactly struck the earth in the middle of Siberia?—is still up for debate...

Since the beginning of the space program, we’ve expected astronauts to be fully-abled athletic overachievers—one-part science geeks, two-part triathletes—a mix the writer Tom Wolfe called “the right stuff.” But what if, this whole time, we’ve had it wrong? In this episode from 2022, reporter Andrew Leland joins blind Linguistics Professor Sheri Wells-Jensen and a crew of 11 other disabled people...
