Radiolab

Saturday Noon
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.

    This hour we pull apart one sentence, written in the hours after September 11th, 2001, that has led to the longest war in U.S. history. We examine how just 60 words of legal language have blurred the line between war and peace.

    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?

    What do frozen horses and a scorching universe have in common? That's what we wanted to know.

    From the stage to the cage, a series of showdowns that leave us wondering about the price of being right ... or coming from the left.

Who Wants To Eat Jellyfish Omelettes? Dolphin Meatballs? Mouse-On-Toast? These Guys

Aaron Birk for NPR

Foodwise, we live in choosy times, mostly choosing "no thank you."

More and more of us choose not to eat meat or fish or eggs or fatty foods. We don't want anything too sugary, too fried, too raw, too strange. We tiptoe through the grocery as if it's a danger zone, hoping not to be tempted by a glazed doughnut.

That Old Rice-Grains-On-The-Chessboard Con, With a New Twist

Robert Krulwich/NPR

Once upon a time, says the science writer David Blatner, there was this con man who made chessboards for high-end clients — in this case, a king.

The craftsman was good; his chessboards were better than beautiful. The king, he knew, loved chess. So he hatched a plan to trick the king into handing over an enormous fortune. His plan? He figured, "This king is not too good at math."

So when the craftsman presented his chessboard at court, he told the king,
