Radiolab

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 Levy eavesdrops on some human-dolphin conversations, from a studio apartment in the Virgin Islands to a research vessel in the Bermuda Triangle.

For much of history, tree canopies were pretty much completely ignored by science. It was as if researchers said collectively, "It's just going to be empty up there, and we've got our hands full studying the trees down here! So why bother?!" But then, around the mid-1980s, a few ecologists around the world got curious and started making their way up into the treetops using any means necessary (ropes, cranes, hot air dirigibles) to document all they could find. It didn't take long for them to realize not only was the forest canopy not empty, it was absolutely filled to the brim with life. You've heard of treehouses? How about tree gardens?!  This week we journey up into the sky and discover Forests above the forest. We learn about the secret powers of these sky gardens from ecologist Korena Mafune, and we follow Nalini Nadkarni as she makes a ground-breaking discovery that changes how we understand what trees are capable of.  P.S. This episode is a layer cake of arboreal surprises (including the reappearance o

Jad started Radiolab roughly 20 years ago. And now he is stepping aside from hosting and producing the show to replenish, to think, to rock in his chair and be with his kids and wife, and maybe make some music. The news has been all over twitter and there’s a letter from Jad and our hosts Latif and Lulu on the website. But in this episode, Jad talks through his decision to leave and the future of the show with Lulu and Latif. And then, as a parting gift, we play him the very first episode of Radiolab (“The Radio Lab” as he called it then). He tells us about biking the CDs over the Brooklyn bridge just before the show was supposed to air, reading the news and weather between segments, and then we just sit back together and listen to where it all began. Jad, for those of us who have been radically changed by the thing you put out into the world, we are both sad to lose you in our ears and endlessly grateful for what you’ve given us.

Last week, Lulu heard an interview that trapped her in her car. She decided to play it for Latif. The interview – originally from a podcast called The Relentless Picnic, but presented by one of Lulu’s current podcast faves, The 11th – is part of an episode of mini pep talks designed to help us all get through this cold, dark, second-pandemic-winter-in-a-row. But the segment that Lulu brings Latif is about someone trying to get through something arguably much more difficult, something a pep talk can’t solve, but that a couple friends — and one very generous stranger — might be able to help make a little more bearable. The episode of The 11th this comes from is “I’m Here to Pep You Up.” The Relentless Picnic is currently running a series of episodes called CABIN, an audio exploration of isolation, which you can listen to here. The organization where Matt volunteers as a counselor is called SUDEP. The Lu Olkowski story Lulu recommends at the end of the episode is “Grandpa,” and the lobster story Latif recommends

It would seem that hackers today can do just about anything they want - from turning on the cellphone in your pocket to holding your life's work hostage. Cyber criminals today have more sophisticated tools, have learned to work collaboratively around the world and have found innovative ways to remain deep undercover in the internet's shadows. This episode, we shine a light into those shadows to see the world from the perspectives of both cybercrime victims and perpetrators. First we meet mother-daughter duo Alina and Inna Simone, who tell us about being held hostage by criminals who have burrowed into their lives from half a world away. Along the way we learn about the legally sticky spot that unwitting accomplices like Will Wheeler find themselves in. Then reporter and author Joseph Menn tells us about the surprisingly lucrative professional hacker structure in places throughout the former Soviet Union. Finally, the co-creator of one of the most notorious online marketplaces to ever exist speaks to us and NP

What was the worst year to be alive on planet Earth?   We make the case for 536 AD, which set off a cascade of catastrophes that is almost too horrible to imagine. A supervolcano. The disappearance of shadows. A failure of bread. Plague rats. Using evidence painstakingly gathered around the world - from Mongolian tree rings to Greenlandic ice cores to Mayan artifacts - we paint a portrait of what scientists and historians think went wrong, and what we think it felt like to be there in real time. (Spoiler: not so hot.)  We hear a hymn for the dead from the ancient kingdom of Axum, the closest we can get to the sound of grief from a millennium and a half ago. The horrors of 536 make us wonder about the parallels and perpendiculars with our own time: does it make you feel any better knowing that your suffering is part of a global crisis? Or does it just make things worse?"Thanks to reporter Ann Gibbons whose Science article "Eruption made 536 ‘the worst year to be alive" got us interested in the first place. In

This past year was a flop. From questionable blockbuster reboots to supply chain shenanigans to worst of all, omnipresent COVID variants. But, in a last ditch effort to flip the flop, we at Radiolab have dredged up the most mortifying, most cringeworthy, most gravity-defying flops we could find. From flops at a community pool to flops at the White House, from a flop that derails a career to flops that give NBA players a sneaky edge, from flops that’ll send you seeking medical advice to THE flopped flop that in a way enabled us all. Take a break from all the disappointment and flop around with us.

When Alana Casanova-Burgess set out to make a podcast series about Puerto Rico, she struggled with what to call it. Until one word came to mind, a word that captures a certain essence of life in Puerto Rico, but eludes easy translation into English. We talk to Alana about her series, and that particular word, then turn to an old story about treating words as signals of something happening just beneath the surface.  Agatha Christie's clever detective novels may reveal more about the inner workings of the human mind than she intended. According to Dr. Ian Lancashire at the University of Toronto, the Queen of Crime left behind hidden clues to the real-life mysteries of human aging in her writing. Meanwhile, Dr. Kelvin Lim and Dr. Serguei Pakhomov from the University of Minnesota add to the intrigue with the story of an unexpected find in a convent archive that could someday help pinpoint very early warning signs for Alzheimer's disease and dementia. Sister Alberta Sheridan, a 94-year-old Nun Study participant, r

Tuck your napkin under your chin.  We’re about to serve up a tale of love, loss, and lamb chops - with a side of genetic modification. Several years ago we told a story about Amy Pearl. For as long as she could remember, Amy loved meat in all its glorious cuts and marbled flavors. And then one day, for seemingly no reason, her body wouldn’t tolerate it.  No steaks. No brisket. No weenies. It made no sense: why couldn’t she eat something that she had routinely enjoyed for decades?  It turned out Amy was not alone. And the answer to her mysterious allergy involved maps, a dancing lone star tick, and a very particular sugar called Alpha Gal.  In this update, we discover that our troubles with Alpha Gal go way beyond food. We go to NYU Langone Health hospital to see the second ever transplant of a kidney from a pig into a human, talk to some people at Revivicor, the company that bred the pig in question, and go back to Amy to find out what she thinks about this brave new world. The original episode was reported b

In this hour of Radiolab, stories of cross-species communication. When we gaze into the eyes of a wild animal, or even a beloved pet, can we ever really know what they might be thinking? Is it naive to assume they're experiencing something close to human emotions? Or is it ridiculous to assume that they AREN'T feeling something like that? We get the story of a rescued whale that may have found a way to say thanks, ask whether dogs feel guilt, and wonder if a successful predator may have fallen in love with a photographer.
