Ella al-Shamahi is one part Charles Darwin, one part Indiana Jones. She braves war zones and pirate-infested waters to collect fossils from prehistoric caves, fossils that help us understand the origin of our species. Her recent hit BBC / PBS series Human follows her around the globe trying to piece together the unlikely story of how early humans conquered the world.  But Ella’s own origins as an evolutionary biologist are equally ...

This is the story of a three-year-old girl and the highest court in the land. The Supreme Court case Adoptive Couple v. Baby Girl is a legal battle that has entangled a biological father, a heart-broken couple, and the tragic history of Native American children taken from their families. We originally released this story back in 2013, when that girl’s fate was still in the balance of various legal decisions. We thought now was a go...

Over the course of millions of years, human voices have evolved to hold startling power. These clouds of vibrating air carry crucial information about who we are–and we rely on them to push ourselves up and out into the physical world.

This week, we’re on a journey to understand how we got our unique sonic fingerprint, the power it affords us, and what happens when it’s taken away.

In the 1920s, a Russian biologist studying onion roots made a surprising discovery: underground, down in the darkness, it seemed like the cells inside the onion roots were making their own … light. 

The “onion root experiment” went on to become something of a cult classic in science, and eventually the biologically-made light was dubbed “biophotons.” In the ensuing century, biophoton discoveries moved from onion roots to bacteria, f...

How a group of 80’s Cuban misfits found rock-and-roll and created a revolution within a revolution, going into exile without ever leaving home.  Reporter Luis Trelles brings us the story of punk rock’s arrival in Cuba and a small band of outsiders who sentenced themselves to death and set themselves free. We originally released this episode back in 2015 in a collaboration with Radio Ambulante, but the story is so fascinating (and, ...

In August we performed a live taping of the show from a theater perched on the edge of Manhattan, overlooking the Hudson River, overshadowed by the wide open night sky. Three stories about voids. One about a fish that screams into the night – and the mystery of its counterpart that doesn’t. Another about a group of women who gazed at the night sky and taught us just how vast the universe is, and a third about a man who talk to alie...

With this episode, we’re putting on our music hat. For a program that relies so much on scoring and sound, it’s not often we talk about the musicians and the music they make that inspire us. Today, that changes. Today, we bring you two stories. Each about musicians that our former host and creator of Radiolab, Jad Abumrad, loves. 

We originally released these stories many years ago, and both start deep in music itself. Then quickly,...

As he finished his medical school exam, David Fajgenbaum felt off.  He walked down to the ER and checked himself in.  Soon he was in the ICU with multiple organ failure.  The only drug for his condition didn’t work. He had months to live, if that.  If he was going to survive, he was going to have to find his own cure. Miraculously, he pulled it off in the nick of time. From that ordeal, he realized that our system of discovering an...

In an episode first released in 2010, then-producer Lulu Miller drives to Michigan to track down the endangered Kirtland’s warbler. Efforts to protect the bird have lead to the killing of cowbirds (a species that commandeers warbler nests), and a prescribed burn aimed at creating a new habitat. Tragically, this burn led to the death of a 29-year-old wildlife technician who was dedicated to warbler restoration. Forest Service employ...

Until recently, scientists assumed humans were the only species in which females went through menopause, and lived a substantial part of their lives after they were no longer able to reproduce. And they had no idea why that happens, and why evolution wouldn’t push females to keep reproducing right up to the end of their lives. But after a close look at some whale poop, and a deep dive into chimp life, we find several new ways of th...

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 Abumrad, Michael Woodrum, Gina Vivona, a...

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 visit to Brian Greene to ask if the l...

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 McSherry duke it out over whether the first...

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 Office circa 1979.

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, like the internet, many people quickl...

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 best friend, she took revenge. Carol's...

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...
