Radiolab

Radiolab is a show about curiosity. Where sound illuminates ideas, and the boundaries blur between science, philosophy, and human experience. Produced by WNYC.

Hello

It's tough to make small talk with a stranger—especially when that stranger doesn't speak your language. (And he has a blowhole.)

Shorts: Happy Birthday Bobby K

It’s Robert’s birthday! (Or it was, anyway, a couple days back.) So today we celebrate with some classic Krulwich radio and a backwards peek into the spirit and sensibility that, in many ways, drives our show.


For his birthday surprise we all listened to some old NPR pieces that Robert did in the 70s, 80s and early 90s — a news piece on the dawn of the ATM, a fake opera on interest rates, and the story of a family business splintered into relatives fighting to be first in the phone book. Along the way, we hear some incredible stories from Robert’s life … 


And, just to celebrate the man whose infectious curiosity draws so many people (including us) to his side … we share with you the kind of gonzo, full-throated Krulwich story we usually can’t include in the show … an epic of secret zoos, sewing machines, an alligator farm, a marching band, and a bus full of French tourists that save the day.

Shorts: For the Birds

Today, a lady with a bird in her backyard upends our whole sense of what we may have to give up to keep a wild creature wild.

Galapagos

Today, the strange story of a small group of islands that raise a big question: is it inevitable that even our most sacred natural landscapes will eventually get swallowed up by humans? And just how far are we willing to go to stop that from happening?


We are dedicating a whole hour to the Galapagos archipelago, the place that inspired Darwin’s theory of evolution and natural selection. 179 years later, the Galapagos are undergoing rapid changes that continue to pose -- and possibly answer -- critical questions about the fragility and resilience of life on Earth.

Shorts: 9-Volt Nirvana

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.

Shorts: ≤ kg

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.
