Radiolab

This week: the story of astrophysicist Charity Woodrum. Charity is an extragalactic astronomer who studies the life and death of galaxies, why some galaxies burn bright and others dim and sputter out. And in the midst of an unthinkable grief in her personal life, she discovers something in the sky – a new kind of light that would guide her path forward.  Special thanks to Megan Stielstra, Jad Abum...

This week, two conversations from the archives about parts of the world that are imperceptible to us, verging on almost unthinkable. We start with a moment of uncertainty in physics. Inspired by an essay written by physicist and novelist Alan Lightman, called The Accidental Universe ( https://zpr.io/4965dUdNqtpQ) , taken from a book of the same name. Former Radiolab co-host Robert Krulwich pays a...

Back in 2017 our colleagues at More Perfect gathered a room full of people together to debate a straight forward question: Can free speech go too far? Today, eight years have passed and plenty has changed, but this question feels alive as ever.  And so we’re re-airing More Perfect’s The Hate Debate. Taped live at WNYC's Jerome L. Greene Performance Space, Elie Mystal, Ken White and Corynne McSherr...

This hour of Radiolab, former co-hosts Jad and Robert set out in search of order and balance in the world around us, and ask how symmetry shapes our very existence -- from the origins of the universe, to what we see when we look in the mirror. Along the way, we look for love in ancient Greece, head to modern-day Princeton to peer inside our brains, and turn up an unlikely headline from the Oval Of...

Have you heard On the Media’s Peabody-winning series The Divided Dial?  It’s awesome and you should, and now you will. In this episode they tell the story of shortwave radio: the way-less-listened to but way-farther-reaching cousin of AM and FM radio. The medium was once heralded as a utopian, international, and instantaneous mass communication tool — a sort of internet-before-the-internet.  But,...

Jilted lovers and disrupted duck hunts provide a very odd look into the soul of the US Constitution. What does a betrayed lover’s revenge have to do with an international chemical weapons treaty? More than you’d think. From poison and duck hunts to our feuding fathers, we step into a very odd tug of war between local and federal law. When Carol Anne Bond found out her husband had impregnated her b...

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...

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...

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 crann...

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 th...

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 questi...

Radiolab is on a curiosity bender. We ask deep questions and use investigative journalism to get the answers. A given episode might whirl you through science, legal history, and into the home of someone halfway across the world. The show is known for innovative sound design, smashing information into music. It is hosted by Lulu Miller and Latif Nasser. Hosted by Simplecast, an AdsWizz company. See...

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, glowi...

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 o...

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 s...

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 Pepperber...

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.  EPI...

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 K...

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...

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.  Keep reading if you’re okay with us spoiling t...

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. Thi...

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...

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 tr...

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...

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 conve...
