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.

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.

View Details

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.

View Details

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.

View Details

You may not give a second thought (or backward glance) to what the toilet whisks away after you do your business.

View Details

View Details

The inhumanly fast world of high-speed trading, an excruciatingly slow experiment, and a physicist plays Zeus.

View Details

View Details

Stories of nature and nurture slamming into each other, & shaping our biological blueprints.

View Details

Mel Blanc was known as "the man of 1,000 voices," but the actual number may have been closer to 1,500. Bugs Bunny, Porky Pig, Tweety, Barney Rubble -- all Mel. His characters made him one of the most beloved men in America. And in 1961, when a car crash left him in a coma, these characters may have saved him.
