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 suburban sp...

They promised to change you. They ended up changing all of us. On July 20, 1969 humanity watched as Neil Armstrong stepped foot on the moon. It was the dazzling culmination of a decade of teamwork, a collective global experience unlike anything before or since, a singular moment in which every human being was invited to feel part of something larger than themself. There was however, one man who was left out. This week on Radiolab we explore what it means to be together and - of course - the cass...

Chimps. Bonobos. Humans. We're all great apes, but that doesn’t mean we’re one happy family. This episode, a mashup of content stretching all the way back to 2010, asks the question, is cross-species co-habitation an utterly stupid idea? Or might it be our one last hope as more and more humans fill up the planet? A chimp named Lucy teaches us the ups and downs of growing up human, and a visit to The Great Ape Trust in Des Moines, Iowa highlights some of the basics of bonobo culture (be careful, ...

A selection of short flights of fact and fancy performed live on stage. Usually we tell true stories at this show, but earlier this spring we were invited to guest host a live show called Selected Shorts, a New York City institution that presents short fiction performed on stage by great actors (you’ll often find Tony, Emmy and Oscars winners on their stage). We treated the evening a bit like a Radiolab episode, selecting a theme, and choosing several stories related to that theme. The stories w...

Remembering is a tricky, unstable business. This hour: a look behind the curtain of how memories are made...and forgotten. The act of recalling in our minds something that happened in the past is an unstable and profoundly unreliable process--it’s easy come, easy go as we learn how true memories can be obliterated, and false ones added. Then, Oliver Sacks joins us to tell the story of an amnesiac whose love for his wife and music transcend his 7-second memory. Our newsletter comes out every Wedn...

An ode to the small, the banal, the overlooked things that make up the fabric of our lives. Most of our stories are about the big stuff: Important or dramatic events, big ideas that transform the world around us or inspire conflict and struggle and change. But most of our lives, day by day or hour by hour, are made up of … not that stuff. Most of our lives are what we sometimes dismissively call “small potatoes.” This week on Radiolab, Heather Radke challenges to focus on the small, the overlook...

In an episode we last featured on our Radiolab for Kids Feed back in 2020, and in honor of its blocking out the Sun for a bit of us for a bit last week, in this episode, we’re gonna talk more about the moon. According to one theory, (psst listen to The Moon Itself if you want to know more) the moon formed when a Mars-sized chunk of rock collided with Earth, the moon coalesced out of the debris from that impact. And it was MUCH closer to Earth than it is today. This idea is taken to its fanciful ...

There’s a total solar eclipse coming. On Monday, April 8, for a large swath of North America, the sun will disappear, in the middle of the day. Everywhere you look, people are talking about it. What will it feel like when the sun goes away? What will the blocked-out sun look like? But all this talk of the sun got us thinking: wait, what about the moon ? The only reason this whole solar eclipse thing is happening is because the moon is stepping in front of the sun. So in today’s episode, we stop ...

As a treat for the first palindrome date of the calendar year 2024, 4/2/24, (for those who use U.S. formatting of dates anyway), we are releasing a special audio palindrome. A piece that plays the same forward and backward. It’s called “Drawn Onward” and it comes from the producers Alan Goffinski and Sarita Bhatt. It originally aired on the wonderful BBC show Short Cuts which curates fresh, experimental, adventurous audio journeys. Special thanks to Alan Goffinski, Sarita Bhatt, Josie Long, Elea...

This is a segment we first aired back in 2011. In it, we hear a story of a very different kind of lost and found. Alan Lundgard, a college art student, fell in love with a fellow art student, Emilie Gossiaux. Nine months after Alan and Emilie made it official, Emilie's mom, Susan Gossiaux, received a terrible phone call from Alan. Together, Susan and Alan tell Jad and Robert about the devastating fork in the road that left Emilie lost in a netherworld, and how Alan found her again. Then, at the ...

On today’s show, we’re excited to share an episode from our friends at the podcast Throughline . Sometimes, the most dangerous and powerful thing a person can do is to stand up not against their enemies, but against their friends. As the United States heads into what will likely be another bitter and divided election year, there will be more and more pressure to stand with our in-groups rather than our consciences. So the Throughline team decided to tell some of the stories of people who have st...

What happens when you combine an axe-wielding microbiologist and a disease-obsessed historian? A strange brew that's hard to resist, even for a modern day microbe. In the war on devilish microbes, our weapons are starting to fail us. The antibiotics we once wielded like miraculous flaming swords seem more like lukewarm butter knives. But today we follow an odd couple to a storied land of elves and dragons. There, they uncover a 1000-year-old secret that makes us reconsider our most basic assumpt...

Two years ago, the United States did something amazing. In response to the mental health crisis the federal government launched 988 - a nationwide, easy to remember phone number that anyone can call anytime and talk to a counselor. It was 911 but for mental health and they hoped that it would save lives. However, if you call 988 today the first thing you hear isn’t a sympathetic counselor. What you hear is hold music. Today, the story of the highest stakes hold music in the universe, the three m...

This episode begins with a rant. This rant, in particular, comes from Dan Engber - a science writer who loves animals but despises animal intelligence research. Dan told us that so much of the way we study animals involves tests that we think show a human is smart ... not the animals we intend to study. Dan’s rant got us thinking: What is the smartest animal in the world? And if we threw out our human intelligence rubric, is there a fair way to figure it out? Obviously, there is. And it’s a live...

In this episode, Maria Paz Gutiérrez does battle against the one absolute truth of human existence and all life… death. After getting a team of scientists to stand in for death (the grim reaper wasn’t available), we parry and thrust our way through the myriad ways that death comes for us - from falling pianos to evolution’s disinterest in longevity. In the process, we see if we can find a satisfying answer to the question “why do we have to die” and find ourselves face to face with the bitter en...

Albert Einstein asked that when he died, his body be cremated and his ashes be scattered in a secret location. He didn’t want his grave, or his body, becoming a shrine to his genius. When he passed away in the early morning hours of April, 18, 1955, his family knew his wishes. There was only one problem: the pathologist who did the autopsy had different plans. In the third episode of “G”, Radiolab’s miniseries on intelligence, first aired back in 2019 we go on one of the strangest scavenger hunt...

As co-host Latif Nasser was putting his kid to bed one night, he noticed something weird on a solar system poster up on the wall: Venus had a moon called … Zoozve. But when he called NASA to ask them about it, they had never heard of Zoozve, and besides that, they insisted that Venus doesn’t have any moons. So begins a tiny mystery that leads to a newly discovered kind of object in our solar system, one that is simultaneously a moon, but also not a moon, and one that waltzes its way into asking ...

Sometimes a seemingly silly question gets stuck in your craw and you can’t shake the feeling that something big lies behind it. We are constantly collecting these kinds of questions from our listeners, not to mention piling up a storehouse of our own “stupid” questions, as we lovingly call them. And a little while back, we noticed a little cluster of questions that seemed to have a shared edgy energy, and all led us to the same place: Our own bodies. So, today on Radiolab, we go down our throats...

First aired way back in 2009, this episode is all about a wonderfully slippery and smarty-pants word for randomness, Stochasticity, and how it may be at the very foundation of our lives. Along the way, we talk to a woman suddenly consumed by a frenzied gambling addiction, hear from two friends whose meeting seems to defy pure chance, and take a close look at some very noisy bacteria.

Karim Ani dedicated his life to math. He studied it in school, got a degree in math education, even founded Citizen Math to teach it to kids in a whole new way. But, this whole time, his whole life, almost, he had this question nagging at him. The question came in the form of a rule in math, NEVER divide by zero. But, why not? Cornell mathematician, and friend of the show, Steve Strogatz, chimes in with the historical context, citing examples of previous provocateurs looking to break the rules o...

First aired back in 2009, this episode is all about one thing, or rather a collection of things. Whether you love 'em or hate 'em, chances are you rely on numbers every day of your life. Where do they come from, and what do they really do for us? This hour: stories of how numbers confuse us, connect us, and even reveal secrets about us.

As a lifeguard, a paramedic, and then an ER doctor, Blair Bigham found his calling: saving lives. But when he started to work in the ICU, he slowly realized that sometimes keeping people (and their hopes) alive just prolongs the suffering. He wrote a book arguing that a too-late death is just as bad as a too-early one, and that physicians and the public alike need to get better at accepting the inevitability of death sooner. As the book hit the bestseller list, Blair’s own father got diagnosed w...

In this short episode that first aired in 2011, a neurologist issues a dare to a ragtime piano player and a famous conductor. When the two men face off in an fMRI machine, the challenge is so unimaginably difficult that one man instantly gives up. But the other achieves a musical feat that ought to be impossible. Reporter Jessica Benko went to Michigan to visit Bob Milne, one of the best ragtime piano players in the world, and a preternaturally talented musician. Usually, Bob sticks to playing p...

Could puberty get any more awkward? Turns out, yes. Writer Patrick Burleigh started going through puberty as a toddler. He had pubic hair before he was two years old and a mustache by middle school. All of this was thanks to a rare genetic mutation that causes testotoxicosis, also known as precocious puberty. From the moment he was born, abnormally high levels of testosterone coursed through his body, just as it had in his father’s body, his grandfather’s body, and his great-grandfather’s body. ...

The definition of life is in flux, complexity is overrated, and humans are shrinking. Viruses are supposed to be sleek, pared-down, dead-eyed machines. But when one microbiologist stumbled upon a GIANT virus, hundreds of times bigger than any seen before, all that went out the window. The discovery opened the door not only to a new cast of microscopic characters with names like Mimivirus, Mamavirus, and Megavirus, but also to basic questions: How did we miss these until now? Have they been aroun...

In this episode we introduce you to a part of our bodies that was invisible to Western scientists until about five years ago; it’s called "the interstitium," a vast network of fluid channels inside the tissues around our organs that scientists have just begun to see, name, and understand. Along the way we look at how new technologies rub up against long-standing beliefs, and how millions of scientists and doctors failed to see what was right in front (and inside!) of their noses. We also find ou...

Back when Robert was kid, he had a chance encounter with then President John F. Kennedy. The interaction began with a hello and ended with a handshake. And like many of us who have touched greatness, 14 year old Robert was left wondering if maybe some of Kennedy would stay with him. Back in 2017, when this episode first aired, Robert found himself still pondering that encounter and question. And so with the help of what was brand new science back then, and a helping hand from Neil Degrasse Tyson...

Russia simply had more bodies to fight with and more steel to kill with.Fast-forward to today, however, and the war is anything but over. Ukraine has held and regained territory with shocking resilience. Stranger still, a small, cheap gadget that up until now was little more than a toy, has been central to their success.Today on Radiolab, we track the deployment of this weapon and wonder w...

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...
