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 th...

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  and solitude , as well as colorful musings on airplane farts and belly flops and Blueberry Earths ,  is leaving the show. So we thought it perfect timing to sit down with her and revisit another brainchild of hers, The Cataclysm Sentence, a collection of advice for The End. To explain: one day i...

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...

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...

Tuesday afternoon, summer of 2017: Scotty Hatton and Scottie Wightman made a decision to help someone in need and both paid a price for their actions that day — actions that have led to a legal, moral, and scientific puzzle about how we balance accountability and forgiveness.  In this 2019 episode, we go to Bath County, Kentucky, where, as one health official put it, opioids have created “a hole t...

Cat Jaffee didn’t necessarily think of herself as someone who loved being alone. But then, the pandemic hit. And she got diagnosed with cancer. Actually, those two things happened on the exact same day, at the exact same hour. In the shadow of that nightmarish timing, Cat found her way to a sport that celebrated the solitude that was forced on her, and taught her how to not only embrace self-relia...

How do you fix a word that’s broken? A word we need when we bump into someone on the street, or break someone’s heart. In our increasingly disconnected secular world, “sorry” has been stretched and twisted, and in some cases weaponized. But it’s also one of the only ways we have to piece together a sense of shared values and beliefs. Through today's sea of sorry-not-sorries, empty apologies, and j...

Tiny buttons have such a hold on us. They can be portals to power, freedom, and destruction. Today, with the help of buttons, we tell you about taking charge of the little things in life, about fortunes made and lost, and about the ease with which the world can end.  Confused? Push the button marked Play. Special thanks for the music of  Brian Carpenter's Ghost Train Orchestra Our newsletter comes...

This week we examine one of nature's most humble creations: crabs. Turns out when you look closely at these little scuttlers, things get surprisingly existential — about how to come into being, how to survive chaos, and how to live. We even examine the possibility of evolutionary destiny. This episode is a two-parter, a double-decker crab cake of sorts. Served up on a bed of lettuce and beautiful...

First aired in 2015, this is an episode about social media, and how, when we talk online, things can quickly go south. But do they have to? In the earlier days of Facebook, we met with a group of social engineers who were convinced that tiny changes in wording can make the online world a kinder, gentler place.  We just have to  agree to be their lab rats. Because Facebook, or something like it, is...

After years of being publicly shamed for “fleecing” the taxpayers with their frivolous and obscure studies, scientists decided to hit back with… an awards show?! This episode , we gate-crash the Grammys of government-funded research, A.K.A. the Golden Goose Awards. The twist of these awards is that they go to scientific research that at first sounds trivial or laughable but then turns out to chang...

In this deep cut from 2012, we are searching for platonic ideals longing for completion, engaged in epic quests for holy grails in science, linguistics, and world peace. And along the way, we’ll meet the dreamers and measure just how impossible their dreams are.  First: a perfect moment. On day 86 of a 3-month trek to and from the South Pole, adventurer Aleksander Gamme ( https://zpr.io/ryaJzt5vaN...
