It's tough to make small talk with a stranger—especially when that stranger doesn't speak your language. (And he has a blowhole.) 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...

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, we consider a series of discoveries that are reshaping our understanding of when and how we can...

Do you believe in ghosts? 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 investigators showed up at his door and made him realize what it really...

The closest we ever came to abolishing the electoral college and why we probably never will.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 hidden in...

Is democracy fundamentally broken? Or does i just need a ... tweak? 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: how do we fix it? We...

Roosevelt, Kennedy, Eisenhower … they all got a pass. But today we peer back at the moment when poking into the private lives of political figures became standard practice. 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...

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 flatlands, prevent erosion and the encroachment of invasive species, usher in sunlight, provide...

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 went back to visit her, month after month, what began as a simple act of motherhood became a...

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 zero, he uses all the available evidence to reimagine the disaster from the perspective of the...

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 coral calendars. 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...

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? Could it parent his kids? Evan feeds his bot the most intimate details about his life, and lets...

Here at the show, we get A LOT of questions, tiny questions, big questions, weird questions, poop questions. Today, we’re dumping the bucket out. 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,...

How a plane crash in Nebraska gave us the modern ER. 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, Dr. Paul Collicott, Irvene Hughe,...

In 2008, the Supreme Court stepped in to settle our fight over the Second Amendment’s meaning. They did. And they didn’t. 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...

Wildfires, a mysterious outbreak, and a question – is there something in the smoke? 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, and reveal...

Birds do it, bees do it...yet science still can't answer the basic question: why do we sleep? 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...

Look up in the sky! It is something that scientists thought could never happen. 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 home together for...

This episode we look at a high profile sporting event where, thanks to a quirk in the tournament rules, the best shot at winning was … to lose. 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....

What would you do if someone’s heart stopped right in front of you? 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 your bed, on the street, on...

Radiolab wishes Oliver Sacks a happy birthday. First aired back in 2013, we originally released this episode to celebrate the 80th birthday of one of our favorite human beings, Oliver Sacks. To celebrate, his good friend, and our former co-host Rober Krulwich, asks the good doctor to look back, and explain how thousands of worms and a motorbike accident led to a brilliant writing career. We have some exciting news! In the “Zoozve” episode, Radiolab named its first-ever quasi-moon, and now...

A man finds himself forever caught between guilt and innocence. In 1995, a tragic fire in Pittsburgh set off a decades-long investigation that sent Greg Brown Jr. to prison. But, after a series of remarkable twists, Brown found himself contemplating a path to freedom that involved a paradoxical plea deal—one that peels back the curtain on the criminal justice system and reveals it doesn’t work the way we think it does.

Can you fit the identity of a whole nation into a dance? Of course not. But we tried anyway. People have been doing the square dance since before the Declaration of Independence. But does that mean it should be THE American folk dance? That question took us on a journey from Appalachian front porches, to dance classes across our nation, to the halls of Congress, and finally a Kansas City convention center. And along the way, we uncovered a secret history of square dancing that made us see...

What does it mean to see – and not see – in your mind? Close your eyes and imagine a red apple. What do you see? Turns out there’s a whole spectrum of answers to that question and Producer Sindhu Gnanasambandan is on one far end. In this episode, she explores what it means to see – and not see – in your mind.

From a suburban sidewalk in southern California, Jad and Robert witness the carnage of a gruesome turf war. Though the tiny warriors doing battle clock in at just a fraction of an inch, they have evolved a surprising, successful, and rather unsettling strategy of ironclad loyalty, absolute intolerance, and brutal violence. David Holway, an ecologist and evolutionary biologist from UC San Diego, takes us to a driveway in Escondido, California where a grisly battle rages. In this quiet...
