Transcript

IRA FLATOW, HOST:

This is SCIENCE FRIDAY, I'm Ira Flatow. How much do you personally worry about global warming? The people at the Gallup Poll have been asking that question every year since 1989, and according to their latest polling figures, there's been a bit of an uptick in the numbers: 55 percent said they worry about climate change - that's up about four points from last year.

Mapping The Birthplace Of Modern Languages

Transcript

IRA FLATOW, HOST:

When you hear somebody speaking Polish, another person speaking Persian, they sound like totally different languages, don't they? But listen more closely and you'll hear similarities, like how one of the Persian words for mother is mada, and in Polish, it's matka. That's because both languages belong to a large family known as the Indo-European languages. A group that contains over 400 languages and dialects: Polish, Persian, English, French, German, Russian, Icelandic. The list goes on.

(APPLAUSE)

FLATOW: Yup, they were cheering again this week at the Jet Propulsion Laboratory. The Mars Rover Curiosity made its first moves on the Red Planet. It wiggled its wheels, and it's rolling away from the landing site, toward a spot called Glenelg, actually you can spell it backwards and forwards the same way because it's going to return there.

IRA FLATOW, HOST:

This is SCIENCE FRIDAY, I'm Ira Flatow. Up next, discovering the universe inside your skull, and it is a universe. According to my next guest, a single cubic centimeter of brain tissue contains as many nerve connections as there are stars in the Milky Way - billions and billions just in a tiny bit of your brain. Never mind the other three pounds of brain matter. It's a vast world inside our skulls, and much of it operates without us really knowing or thinking much about it or even understanding it.

The lab was called Wardenclyffe, and it was built by Nikola Tesla, a wizard of electrical engineering whose power systems lit up the Chicago World's Fair in 1893 and harnessed the mighty Niagara Falls.
