Science Friday is your trusted source for news and entertaining stories about science. We started as a radio show, created in 1991 by host and executive producer Ira Flatow. Since then, we’ve grown into much more: We produce award-winning digital videos and publish original web content covering everything from octopus camouflage to cooking on Mars.

The Myth of the Woolly Bear

Nov 8, 2013

JOHN DANKOSKY, HOST:

And it's time for the Video Pick of the Week. And joining me now is video producer Luke Groskin. Hello there, Luke.

LUKE GROSKIN, BYLINE: Hi, John.

DANKOSKY: So what do you got for us this week?

GROSKIN: Well, the video pick this week is the myth of the woolly bear.

DANKOSKY: The woolly bear?

GROSKIN: Yes. And we're not talking about the ursine type of bear, like a grizzly o black bear. We're talking about the caterpillars.

DANKOSKY: The little fuzzy guy, he's sort of rust-colored, kind of black?

India and NASA Home In on Mars

Nov 8, 2013

UNIDENTIFIED MAN #1: Zero plus one, two, three, four...

(APPLAUSE)

UNIDENTIFIED MAN #2: Liftoff.

UNIDENTIFIED MAN #3: Liftoff normal.

(APPLAUSE)

JOHN DANKOSKY, HOST:

That's the sound from Mission Control in Sriharikota, India, this past Tuesday. The Indian Space Research Organization launched the Mangalyaan Orbiter to probe the Martian atmosphere. It'll take nearly one year for the orbiter to reach Mars and, if it does, India will be the fourth space program to successfully reach the Red Planet.

Navigating Dietary Supplement Regulations

Nov 8, 2013

JOHN DANKOSKY, HOST:

This is SCIENCE FRIDAY. I'm John Dankosky. Ira Flatow is away. If you walk into any nutritional supplement store today, it seems there are thousands of herbal remedies to treat anything that ails you: Echinacea for colds, dandelion root to help with water retention, grapeseed to promote healthy aging. So many people are including dietary supplements in their daily routine that it's now become a $5 billion industry.

IRA FLATOW, HOST:

When you think about space, usually the big questions come to mind. Is there life on Mars? Did time and space exist before the Big Bang? How do our bodies react to long periods of time in zero gravity? What about some of the smaller questions?

CHRIS HADFIELD: I noticed recently that my fingernails are getting a little long, so it's time to cut your fingernails in Zero G. And now if I just cut my fingernails here, they're going to float everywhere. They'll get in your eyes, people will breathe them. Not good.
