Radiolab

This holiday season, we want to take you on a trip around the heavens. First, co-host Latif Nasser, with the help of Nour Raouafi, of NASA, and an edge-cutting piece of equipment, explain how we may finally be making good on Icarus’s promise. Then, co-host Lulu Miller and Ada Limón talk about how a poet laureate goes about writing an ode to one of Jupiter’s moons. And one more thing! It is almost...

The early bird gets the worm. What goes around, comes around. It’s always darkest just before dawn. We carry these little nuggets of wisdom—these adages—with us, deep in our psyche. But recently we started wondering: are they true? Like, objectively, scientifically, provably true? So we picked a few and set out to fact check them. We talked to psychologists, neuroscientists, runners, a real estate...

Back in 2012, when we were putting together our live show In the Dark, Jad and Robert called up Dave Wolf to ask him if he had any stories about darkness. And boy, did he. Dave told us two stories that became the finale of our show. Back in late 1997, Dave Wolf was on his first spacewalk, to perform work on the Mir (the photo to the right was taken during that mission, courtesy of NASA.). Dave was...

In August of 1973, Jan-Erik Olsson walked into the lobby of a bank in central Stockholm. He fired his submachine gun at the ceiling and yelled “The party starts now!” Then he started taking hostages. For the next six days, Swedish police and international media would tie themselves in knots trying to understand what seemed to them a sordid attachment between captor and captives. And this fixation,...

In today’s story, which originally aired in 2014, we meet a very special cylinder. It's the gold standard (or, in this case, the platinum-iridium standard) for measuring mass. For decades it's been coddled and cared for and treated like a tiny king. But, as we learn from writer Andrew Marantz, things change—even things that were specifically designed to stay the same. Special thanks to Ken Alder,...

When he rounded them up, he had a 100. A few months ago, Wendy Zukerman invited our own Latif Nasser to come on her show, and, of course, he jumped at the chance.  Laughter ensued, as they set off to find the "The Funniest Joke in the World." When you just Google something like that, the internet might serve you, "What has many keys but can't open a single lock??” (Answer: A piano). So they had to...

It's hard to start a conversation with a stranger—especially when that stranger is, well, different. He doesn't share your customs, celebrate your holidays, watch your TV shows, or even speak your language. Plus he has a blowhole. In this episode, which originally aired in the summer of 2014, we try to make contact with some of the strangest strangers on our little planet: dolphins. Producer Lynn...

As we grow up, there are little windows of time when we can learn very, very fast, and very, very deeply. Scientists call these moments, critical periods. Real, neurological, biological states when our brain can soak up information like a sponge. Then, these windows of learning close. Locking us in to certain behaviors and skills for the rest of our lives. But … what if we could reopen them? Today...

In an episode we first aired in 2014, we meet a man named Dennis Conrow, who was stuck. After a brief stint at college, he’d spent most of his 20’s back home with his parents, sleeping in his childhood room. And just when he finally struck out on his own, fate intervened. He lost both his parents to cancer. So Dennis was left, back in the house, alone. Until one night when a group of paranormal in...

As the US Presidential Election nears, Radiolab covers the closest we ever came to abolishing the Electoral College. In the 1960s, then-President Lyndon Johnson approached an ambitious young Senator known as the Kennedy of the Midwest to tweak the way Americans elect their President. The more Senator Birch Bayh looked into the electoral college the more he believed it was a ticking time bomb hidde...

Back in 2018, when this episode first aired, there was a feeling that democracy was on the ropes.  In the United States and abroad, citizens of democracies are feeling increasingly alienated, disaffected, and powerless.  Some are even asking themselves a question that feels almost too dangerous to say out loud: is democracy fundamentally broken?   Today on Radiolab, we ask a different question: ho...

In 1987, Gary Hart was a young charismatic Democrat, poised to win his party’s nomination and possibly the presidency. Many of us know the story of what happened next, and even if you don’t, it’s a familiar tale. Back in 2016, we examined how, when this happened, politicians and political reporters found themselves in uncharted territory. And with help from author Matt Bai, we looked at how the ev...

As dead as they seem, tree stumps are hubs of life and relationships.  Co-host Lulu Miller is back with another season of her hit spinoff show Terrestrials , and to celebrate, we’re sharing the first episode with you. From stumps to snags, dead wood provides habitat for rodents, falcons, insects, and even humans. Stumps hold together the forest floor, give hunting perches to birds of prey in flatl...

A mile under the ocean, we get to watch an octopus perform a heroic act of heart and determination. First aired back in 2020, this episode follows the story of an octopus living one mile under the ocean as she performs a heroic act of heart and determination. In 2007, Bruce Robison’s robot submarine stumbled across an octopus settling in to brood her eggs. It seemed like a small moment. But as he...

Today we follow a sleuth who has spent over a decade working to solve an epic mystery hiding in plain historical sight: did anyone survive the eruption of Mount Vesuvius in 79AD?  Tired of hearing the conventional narrative that every Pompeiian perished without any evidence to back it up, Classicist Steven Tuck decides to look into it himself. Although he is nearly two millennia late to ground zer...

This episode first aired back in December of 2013, and at the start of that new year, the team was cracking open fossils, peering back into ancient seas, and looking up at lunar skies only to find that a year is not quite as fixed as we thought it was. With the help of paleontologist Neil Shubin, reporter Emily Graslie and the Field Museum's Paul Mayer we discover that our world is full of ancient...

One man secretly hands off more and more of his life to an AI voice clone. Today, we feature veteran journalist Evan Ratliff who - for his new podcast Shell Game - decided to slowly replace himself bit by bit with an AI voice clone, to see how far he could actually take it. Could it do the mundane phone calls he’d prefer to skip? Could it get legal advice for him? Could it go to therapy for him? C...

First aired back in 2017, here’s a show of questions and, sometimes, answers. Cause, we get a lot of questions. Like, A LOT of questions. Tiny questions, big questions, short questions, long questions. Weird questions. Poop questions. We get them all. And over the years, as more and more of these questions arrived in our inbox, what happened was, guiltily, we put them off to the side, in a bucket...

February 1976. A flight out of California turned catastrophic when it crashed into a farm in rural Nebraska. What happened that night at the local hospital, and crucially, what went wrong, would inspire a global sea-change in how emergency rooms operate and fundamentally alter the way doctors think in a crisis. Special thanks to Jody and Jay Upright, Heather Talbott, Dr. Ron Simon, Dr. John Sutyak...

Given that we’re all gearing up for the Presidential race, and how gun rights and regulations are almost always centerstage during these times. Today, we’re re-releasing a More Perfect episode that aired just after the October 2017 Las Vegas shooting. It is an episode that attempts to make sense of our country’s fraught relationship with the Second Amendment. For nearly 200 years of our nation’s h...

Two scenes. In the first, a doctor gets a call — the hospital she works at is having an outbreak of unknown origin, in the middle of the worst wildfire season on record. In the second, an ecologist stands in a forest, watching it burn. Through very different circumstances, they both find themselves asking the same question: is there something in the smoke? This question will bring them together, a...

We had a question back in 2007, about a thing every creature on the planet does--from giant humpback whales to teeny fruit flies. Why do we all sleep? What does it do for us, and what happens when we go without? We take a peek at iguanas sleeping with one eye open, get in bed with a pair of sleep-deprived new parents, and eavesdrop on the uneasy dreams of rats.  We have some exciting news! In the...

High above the banks of the Mississippi river, a nest holds the secret life of one of America’s most patriotic creatures. Their story puzzles scientists, reinforces indigenous wisdom, and wows audiences, all thanks to a park ranger named Ed, and a well-placed webcam. If you want to spoil the mystery, here ya go: it’s a bald eagle. Actually, it’s three bald eagles. A mama bird and daddies make a ho...

To celebrate the imminent start of the Summer Olympic Games in Paris, France we have an episode originally reported in 2016. No matter what sport you play, the object of the game is to win. And that’s hard enough to do. But we found a match where four top athletes had to do the opposite in one of the most high profile matches of their careers. Thanks to a quirk in the tournament rules, their best...

We get it… the world feels too bleak and too big for you to make a difference. But there is one thing - one simple tangible thing - you can do to make all the difference in the world to someone, possibly even a loved one, at arguably the worst moment of their life. Statistics show that 1 out of every 5 people on earth will die of heart failure. Cardiac arrests can happen anywhere, anytime - in you...
