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)...

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...

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...

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 f...

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 s...

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 t...

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 d...

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...

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....

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 fo...

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, a...

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. So we thought it per...

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...

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 th...

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 detonate...

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 understandi...

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 au...

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 o...

Foreign enemies have seldom brought war to U.S. soil… right? In this episode from 2017, we tell you strange stories of foreign enemies landing on our shore. From bombs floating across the country without a sound (or even a discussion), to Nazi prisoners of war leading placid lives in towns nationwide, listen to how war quietly wormed its way into the heartland of the United States. Our newsletter...

Testudinology. Enigmatology. Hagfishology. Raccoonology. Meteorology. Chronobiology. Chickenology. Delphinology. Bryology. Vampirology. Zymology. Echinology. Screamology. Melaninology. Dolorology. In this episode, we introduce you to one of our all-time favorite science podcasts. Ologies . A show that’s a kindred spirit to ours, but also… very different. In each episode, Host Alie Ward interviews...

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....

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...

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 ge...

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...
