Radiolab

Sunday 7 p.m.
Jad Abumrad & Robert Krulwich
Robert Krulwich

Radiolab is an experiential investigation that explores themes and ideas through a patchwork of people, sounds, and stories. In each episode, Radiolab experiments with sound and style allowing science to fuse with culture, and information to sound like music.

Hosted by Jad Abumrad with co-host Robert Krulwich, Radiolab is designed for listeners who demand skepticism but appreciate wonder; who are curious about the world, but also want to be moved and surprised.

    Learn a new language faster than ever! Leave doubt in the dust! Be a better sniper! Could you do all that and more with just a zap to the noggin? Maybe.

    Sally Adee, an editor at New Scientist, was at a conference for DARPA - The Defense Advanced Research Projects Agency - when she heard about a way to speed up learning with something called trans-cranial direct current stimulation (tDCS). A couple years later, Sally found herself weilding an M4 assualt rifle, picking off enemy combatants with a battery wired to her temple. Of course, it was a simulation, but Sally's sniper skills made producer Soren Wheeler wonder what we should think of the world of brain stimulation. 

    In the last couple years, tDCS has been all over the news. Researchers claim that juicing the brain with just 2 milliamps (think 9-volt battery) can help with everything from learning languages, to quitting smoking, to overcoming depression. We bring Michael Weisend, neuroscientist at Wright State Research Institute, into the studio to tell us how it works (Bonus: you get to hear Jad get his brain zapped). Peter Reiner and Nick Fitz of the University of British Columbia help us think through the consequences of a world where anyone with 20 dollars and access to Radioshack can make their own brain zapper. And finally, Sally tells us about the unexpected after-effects of a day of super-charged sniper training and makes us wonder about world where you can order up a state of mind.

    A plum-sized lump of metal takes us from the French Revolution to an underground bunker in Maryland as we try to weigh the way we weigh the world around us.

    This hour we investigate the objects around us, their power to move us, and whether it's better to look back or move on, hold on tight or just let go.

    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 tiny (really tiny, it’s in an elevator shaft) museum in Manhattan. You can visit them to see the 3D printed skull, along with the other wonderful things in their collection: mosquitoes swatted mid-bite, toothpaste tubes from around the world, and much more.


    Thanks to JP Brown, Emily Graslie and Robert Martin at the Field Museum in Chicago for scanning the skull. Thanks to Curtis Schmitt and shootdigital for refining the scan. Thanks to Bre Pettis and Jenifer Howard at MakerBot for guiding us through the world of 3D printing.

    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.

Mugged By Sound, Rescued By A Waitress

You walk into a room. There are people there, cars outside, dogs, phones ring, the radio is on, somebody coughs; it's the pleasant blur of a busy world, until something, someone catches your attention. Then you lean in, the other sounds fade back, and you focus. That's how listening works — for most of us.

Death, But Softly

It was 1569, or maybe early 1570, when it happened: A young French gentleman was out for a ride with his workers, all of them on horseback, when suddenly, "like a thunderbolt," he felt something thick and fleshy slam him from behind. (It was an overzealous, galloping assistant who couldn't stop in time.) Michel de Montaigne's horse crumbled, he went flying up, then down, he crashed to the ground. Then things went black.

When he came to, a minute or so later, he says,

Finnish Underwater Ice Fishing Mystery Finally Solved

That's ordinary air pouring out of the pail.

I'm going to take you somewhere, but before I do, I should warn you that there's something not quite right about what you'll see. This place I'm going to show you will be astonishingly beautiful. It will be cold. It will be wet. But it will also be a touch — more than a touch — mysterious. So watch carefully.
