Radiolab

  Today, the story of one little thing that has radically changed what we know about humanity’s humble beginnings and the kinds of creatures that were out to get us way back when.   Wits University Professor Lee Berger and Dr. Chris Stringer from London’s Natural History Museum explain how a child’s skull, found in an ancient cave, eventually helped answer one of our oldest questions: Where do we come from? Then Lee takes us on a journey to answer a somewhat smaller question: how did that child die? Along the way, we visit Dr. Bernhard Zipfel at Wits University in Johannesburg to actually hold the skull itself.   We wanted to give you a chance to hold the skull, too. So we did a little experiment: we made a 3D scan of it. If you visit our page on Thingiverse, you’ll see the results. Anyone with access to a 3D printer can print their own copy of the skull. (We printed a bunch, with help from our friends at MakerBot—there’s even a purple one with sparkles.)   We also collaborated with the folks at Mmuseumm, a t

It’s hard to think of anything more rational, more logical and impersonal than a number. But what if we’re all, universally, also deeply attuned to how numbers … feel? Why 2 is warm, 7 is strong and 11 is downright mystical.    

From boom bap to EDM, we look at the line between hip-hop and not, and meet a defender of the genre that makes you question... who's in and who's out.

They buzz. They bite. And they have killed more people than cancer, war, or heart disease. Here’s the question: If you could wipe mosquitoes off the face of the planet, would you?

This hour, we examine three very different kinds of black boxes—those peculiar spaces where it’s clear what’s going in, we know what’s coming out, but what happens in-between is a mystery. From the darkest parts of metamorphosis, to a sixty year-old secret among magicians, to the nature of consciousness itself, we confront the stubborn gaps in our understanding.

At the start of this new year we crack open some fossils, peer back into ancient seas, and look up at lunar skies to find that a year is not quite as fixed as we thought it was.  

Jilted lovers and disrupted duck hunts provide a very odd look into the soul of the US Constitution.

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.

Cataclysmic destruction. Surprising survival. In this new live stage performance, Radiolab turns its gaze to the topic of endings, both blazingly fast and agonizingly slow.

Scientists' obsession with one particular man - and with the tiny scraps of evidence left in the wake of his death - gives us a surprisingly intimate peek into the life of someone who should've been lost to the ages.

Legions of athletes, sports gurus, and scientists have tried to figure out why Kenyans dominate long-distance running. In this short, we stumble across a surprising, and sort of terrifying, explanation.

When we first released Famous Tumors, Rebecca Skloot's book about the life and legacy of Henrietta Lacks (and her famous cells) had just hit the shelves. Since then, some interesting things have happened to both Henrietta's cells and her family. So, 4 years later, we have a newly updated show!

For many of us, quicksand was once a real fear -- it held a vise-grip on our imaginations, from childish sandbox games to grown-up anxieties about venturing into unknown lands. But these days, quicksand can't even scare an 8-year-old. In this short, we try to find out why. 

You may not give a second thought (or backward glance) to what the toilet whisks away after you do your business. But we got wondering -- where would we wind up if we thought of flushing as the start, and not the end, of a journey? In this short, we head out to trace the trail of sludge...from Manhattan, to wherever poop leads us.

We've all felt it, that irresistible urge to point the finger. But new technologies are complicating age-old moral conundrums about accountability. This hour, we ask what blame does for us -- why do we need it, when isn't it enough, and what happens when we try to push past it with forgiveness and mercy?

In this short, Jad puts on his music hat and shares his love of Dawn of Midi, a band that he recently started using on the show.

What do you do in the face of a monstrous disease with a 100% fatality rate? In this short, a Milwaukee doctor tries to knock death incarnate off its throne.

From medicine to the movies, the horrifying to the holy, and history to the present day -- we're kinda obsessed with blood. This hour, we consider the power and magic of the red liquid that runs through our veins.

One of our favorite human beings turns 80 this week. To celebrate, Robert asks Oliver Sacks to look back on his career, and explain how thousands of worms and a motorbike accident led to a brilliant writing career.

Producer Lu Olkowski brings us the story of a tightly-knit family caught on opposite sides of a very big divide. If you ask Ally Manning's mom and sister, they'll tell you there's no question: they're black. But as a teenager, Ally decided that what was true for them didn't make sense for her.
