While scouring the Sonoran Desert for objects left behind by migrants crossing into the United States, anthropologist Jason De León happened upon something he didn't expect to get left behind: a human arm, stripped of flesh. This macabre discovery sent him reeling, needing to know what exactly happened to the body, and how many migrants die that way in the wilderness. In researching border-crosser deaths in the Arizona desert, he noticed something surprising. Sometime in the late-1990s, the numb...

Originally aired in 2018, this episode features reporter Brena Farrell as a new mom. Her son gave her and her husband a scare -- prompting them to call Poison Control. For Brenna, the experience was so odd, and oddly comforting, that she decided to dive into the birth story of this invisible network of poison experts, and try to understand the evolving relationship we humans have with our poisonous planet. As we learn about how poison control has changed over the years, we end up wondering what ...

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. In the face of this, Hank Green (a long time environmentalist and science educator behind SciShow , Crash Course , and more), took to social media to put things in context, to keep people focused on what we can do about clim...

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. Now, new technol...

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. Last, we go...

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. It’s a story about a death, bu...

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...

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. No matter what happens, who gets hurt, or what harm is done, tech compan...

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. Photographs, names, entire articles...

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. Producer Annie McEwen dives into one idea t...

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. They embark on a mission to prove not just that they have what it takes to go to space, but that dis...

At a tree ring conference in the relatively treeless city of Tucson, Arizona, three scientists walk into a bar. The trio gets to talking, trying to explain a mysterious set of core samples from the Florida Keys. At some point, they come up with a harebrained idea: put the tree rings next to a seemingly unrelated dataset. Once they do, they notice something that no one has ever noticed before, a force of nature that helped shape modern human history and that is eerily similar to what’s happening ...

This is a story about your butt. It’s a story about how you got your butt, why you have your butt, and how your butt might be one of the most important and essential things for you being you, for being human. In this episode from 2019, Reporter Heather Radke and Producer Matt Kielty talk to two researchers who followed the butt from our ancient beginnings through millions of years of evolution, all the way to today, out to a valley in Arizona, where our butts are put to the ultimate test.

Sad news for all of us: producer Rachael Cusick— who brought us soul-stirring stories rethinking grief (https://zpr.io/GZ6xEvpzsbHU) and solitude ( https://zpr.io/eT5tAX6JtYra ), as well as colorful musings on airplane farts ( https://zpr.io/CNpgUijZiuZ4 ) and belly flops ( https://zpr.io/uZrEz27z63CB ) and Blueberry Earths ( https://zpr.io/EzxgtdTRGVzz )— is leaving the show.

Given reporter Julia Longoria’s long love affair with the Supreme Court, it’s no surprise she’s become the new host of More Perfect (https://zpr.io/4R9fMg9gJ96k), a show all about how the Supreme Court got to be so… supreme. This week, we talk to Julia about her journey to the host seat, and we highlight an episode she produced for Radiolab in 2019 about a specific case: González v. Williams. In 1903 the U.S. Supreme Court refused to say that Isabel González was a citizen of the United States. T...

Shipworms. Hairy Chested Yeti Crabs. Parasitic Barnacles in the cloaca of Greenland Sharks. These are the types of creatures Sabrina Imbler, a columnist at Defector, likes to write about. The stranger, the better. In this episode, Imbler discusses how they balance maintaining scientific rigor while also drawing inspiration and metaphor from the animal world. Then they read a stirring essay from their new book, How Far the Light Reaches: A Life in Ten Sea Creatures . It’s about the sand striker, ...

Ross McNutt has a superpower: he can zoom in on everyday life, then rewind and fast-forward to solve crimes in a shutter-flash. But should he? In 2004, when casualties in Iraq were rising due to roadside bombs, Ross McNutt and his team came up with an idea. With a small plane and a 44 megapixel camera, they figured out how to watch an entire city all at once, all day long. Whenever a bomb detonated, they could zoom into that spot and then, because this eye in the sky had been there all along, th...

In the 1970s, as LGBTQ+ people in the United States faced conservatives whose top argument was that homosexuality is “unnatural,” a pair of young scientists discovered on a tiny island off the coast of California a colony of seagulls that included… a significant number of female homosexual couples making nests and raising chicks together. The article that followed upended the culture’s understanding of what’s natural and took the discourse on homosexuality in a whole new direction. In this episo...

At the 1998 Olympics in Nagano, Japan, one athlete pulled a move that, as far as we know, no one else had ever attempted. In this episode, first aired in the Spring of 2016, we tell you about Surya Bonaly. Surya was not your typical figure skater: she is black, she is athletic, and she didn’t seem to care about artistry. Her performances—punctuated by triple jumps and other power moves—thrilled audiences around the world. Yet commentators claimed she couldn’t skate and judges never gave her high...

In 2021, editor Alex Neason's grandfather passed away. On his funeral program, she learned the name of his father for the first time: Wilson Howard. Not Neason. Howard. And when she asked her family why his last name was different from everybody else's, nobody had an answer. In this episode, we tag along as Alex searches for answers through swampy cemeteries, libraries, and archives in the heart of south Louisiana: who was her great grandfather, really? Is she supposed to be a Neason? Where did ...

At first glance, Golden Balls was just like all the other game shows — quick-witted host, flashy set, suspenseful music. But underneath all that, each episode asked a very serious question: can you ever really trust another person? Executive producer Andy Rowe explains how the show used a whole lot of money and a simple set of rules to force us to face the fact that being good might not end well. The result was a show that could shake your faith in humanity — until one mild-mannered fellow unvei...

Heaven and hell, Judgement Day, monotheism — these ideas all came from one ancient Persian religion: Zoroastrianism. Also: Sky Burials. Zoroastrians put their dead on top of a structure called The Tower of Silence where vultures devour the body in a matter of hours. It’s clean, efficient, eco-friendly. It’s how it’s been for thousands of years. Until 2006. That’s when a Zoroastrian woman living in Mumbai snuck up into the tower and found bloated, rotting bodies everywhere. The vultures were gone...

Abortion pills — a combo of two drugs, mifepristone and misoprostol — are on notice: on April 7, 2023, a federal judge said the FDA’s approval of mifepristone was invalid. And then, not more than an hour later, another federal judge in a separate case said that mifepristone had to stay on the market in certain states. With these two contradictory rulings, mifepristone — and medical abortion, in general — is in the crosshairs. So, today, we want to rewind to an episode we made last year. It looks...

How much does knowledge cost? While that sounds like an abstract question, the answer is surprisingly specific: $3,096,988,440.00. That’s how much the business of publishing scientific and academic research is worth. This is the story of one woman’s battle against a global network of academic journals that underlie published scientific research. In 2011, Alexandra Elbakyan had just moved home to Kazakhstan after a disappointing few years trying to study neuroscience in the United States when she...

In this 2019 episode, we go to Bath County, Kentucky, where, as one health official put it, opioids have created “a hole the size of Kentucky.” We talk to the people on all sides of this story about stemming the tide of ove...
