Radiolab

This is episode five of Swimming with Shadows: A Radiolab Week of Sharks.

Today, the strange, squirmy magic behind how sharks make more sharks. Drills. Drama. Death. Even a coliseum of baby sharks duking it out inside mom’s womb. And a man on a small island in the Mediterranean trying, against all odds, to give baby sharks a chance in a little plastic aquarium in his living room. Can a human raise a shark? And if so, what good is th...

This is episode four of Swimming with Shadows: A Radiolab Week of Sharks.

Alison Kock was working at a car wash in Cape Town when she made a discovery that completely changed the course of her life. Inside a customer’s trunk, she found photographs of white sharks flying so high above the water they looked like airplanes. She followed those photographs to False Bay, “the Great White Capital of the World.” These sharks, in this place,...

This is episode three of Swimming with Shadows: A Radiolab Week of Sharks.

Today, we take a trip across the world, from the south coast of Australia to … Wisconsin. Here, scientists are scouring shark blood to find one of nature’s hidden keys, a molecular superhero that might unlock our ability to cure cancer: shark antibodies. They’re small. They’re flexible. And they can fit into nooks and crannies on tumors that our antibodies ca...

This is episode two of Swimming with Shadows: A Radiolab Week of Sharks.

Jaws spawned a thousand imitators: sharks in tornados, sharks in avalanches, sharks that battle giant octopuses. Hollywood has officially turned sharks into monsters of every shape and size. And yet, somehow, there will always be more.

But drop below the surface, into the cold, quiet blue, and another creature appears. One that has survived mass extinctions, out...

Episode one of Swimming with Shadows: A Radiolab Week of Sharks.

Rodney Fox went into the ocean one summer day in 1963. He came out barely alive, his body torn apart by a great white shark. At the time, it was one of the worst shark attacks ever survived.

After he recovered, he was pulled back into the shadowy world he feared most. Again and again and again. That shark attack left behind a question that still lingers, for Rodney, and...

In the summer of 1975, Jaws scared an entire generation out of the water. The film burned an idea into our cultural memory: they are mindless, man-eating monsters. We set out to tell a different story about sharks. Five stories over five days. We tear down deep-seated myths about sharks, plunge into the water with them, and find sharks that explode our sense of what they are – flying sharks, glowing sharks, baby sharks, sharks unde...

We first aired this episode in 2012, but at the show we’ve been thinking a lot about resilience and repair so we wanted to play it for you again today. It’s about a man who experienced maybe one of the most chilling traumas… twice. But then, it leads us to a story of generational repair. 

On the morning of August 6th, 1945, Tsutomu Yamaguchi was in Hiroshima on a work trip. He was walking to the office when the first atomic bomb was...

Doctor and special correspondent, Avir Mitra takes Lulu on an epic journey live on stage at a little basement club called Caveat, here in New York. Starting with an ingredient in breastmilk that babies can’t digest, a global hunt that takes us from Bangladesh to the Mennonite communities here in the US, we discover an ancient symbiotic relationship that might be on the verge of disappearing.  So sip a vicarious cocktail, settle in,...

Animals rescue people all the time, but not like this. In this episode, first aired more than a decade ago, Jim Eggers is a 44-year-old man who suffers from a problem that not only puts his life at risk—it jeopardizes the safety of everybody around him. But with the help of Sadie, his pet African Grey Parrot, Jim found an unlikely way to manage his anger. African Grey Parrot expert Irene Pepperberg helps us understand how this coul...

Today you can convert speech to text with the click of a button. Youtube does it for all our videos. Our phones will do it in real time. It’s frictionless. And yet, if it weren’t for an unlikely crew of protesters and office workers, it might still be impossible. 

This week, the story of our attempts to make the spoken visible. The magicians who tried. And the crazy spell that finally did it.

Now that we have the ability to see inside the brain without opening anyone's skull, we'll be able to map and define brain activity and peg it to behavior and feelings. Right? Well, maybe not, or maybe not just yet. It seems the workings of our brains are rather too complex and diverse across individuals to really say for certain what a brain scan says about a person. But Nobel prize winner Eric Kandel and researcher Cynthia Fu tel...

What happens when a voice emerges? What happens when one is lost? Is something gained? A couple months ago, Lulu guest edited an issue of the nature magazine Orion. She called the issue “Queer Planet: A Celebration of Biodiversity,” and it was a wide-ranging celebration of queerness in nature. It featured work by amazing writers like Ocean Vuong, Kristen Arnett, Carmen Maria Machado and adrienne maree brown, among many others. But ...

Today we bring you a story stranger than fiction. In 2006, paleobiologist Natalia Rybczynski took a helicopter to a remote Arctic island near the North Pole, spending her afternoons scavenging for ancient treasures on the ground. One day, she found something the size of a potato chip. Turns out, it was a three and half million year old chunk of bone.

For years, scientists thought nothing could live above 73℃/163℉.  At that temperature, everything boiled to death. But scientists Tom Brock and Hudson Freeze weren’t convinced. What began as their simple quest to trawl for life in some of the hottest natural springs on Earth would, decades later, change the trajectory of biological science forever, saving millions of lives—possibly even yours.

This seismic, totally unpredictable dis...

In honor of our Earth, on her day, we have two stories about the overlooked, ignored, and neglected parts of nature. In the first half, we learn about an epic battle that is raging across the globe every day, every moment. It's happening in the ocean, and your very life depends on it. In the second half, we make an earnest, possibly foolhardy, attempt to figure out the dollar value of the work of bats and bees as we try to keep our...

A couple years ago, an entomologist named Martha Weiss got a letter from a little boy in Japan saying he wanted to replicate a famous study of hers. We covered that original study on Radiolab more than a decade ago in an episode called Goo and You – check it out here – and in addition to revealing some fascinating secrets of insect life, it also raises big questions about memory, permanence and transformation. The letter Martha rec...

In an episode first aired in 2012, Lulu Miller introduces us to Jeff Lockwood, a professor at the University of Wyoming, who spent a part of his career studying a particularly ferocious set of insects: Gryllacrididae. Or, as Jeff describes them, "crickets on steroids." They have crushingly strong, serrated jaws, and they launch all-out attacks on anyone who gets in their way--whether it's another cricket, or the guy trying to take ...

Earth can sustain life for another 100 million years, but can we?

In this episode, we partnered with the team at Planet Money to take stock of the essential raw materials that enable us to live as we do here on Earth—everything from sand to copper to oil— and tally up how much we have left. Are we living with reckless abandon? And if so, is there even a way to stop? This week, we bring you a conversation that’s equal parts terrifyin...

We all think we know the story of pregnancy. Sperm meets egg, followed by nine months of nurturing, nesting, and quiet incubation. this story isn’t the nursery rhyme we think it is. In a way, it’s a struggle, almost like a tiny war. And right on the front lines of that battle is another major player on the stage of pregnancy that not a single person on the planet would be here without. An entirely new organ: the placenta.

In this ep...
