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.

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.

This is SCIENCE FRIDAY; I'm Ira Flatow. Last week, I was in southern Idaho, and it was snowing in August, or at least it looked like it. Actually, it was raining ash, closing down airports, forcing people to remain inside, many miles away from the forest fire flames.

This is SCIENCE FRIDAY, I'm Ira Flatow. Up next, discovering the universe inside your skull, and it is a universe.

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.

The Avengers and Expendables 2 are two of the summer's biggest movies, and they share a common theme: a band of heroes trying to save the day.

Film buff Murray Horwitz — with some help from Talk of the Nation listeners — suggests alternative movies to watch at home if you like that theme, but don't want to stand in long lines at the box office.

This is TALK OF THE NATION. I'm Neal Conan in Washington. As the U.S. and NATO start to withdraw combat forces from Afghanistan, many in Kabul are considering the lessons of history this summer, and two years in particular: 1989 and the withdrawal of Soviet troops after 10 years; 1992 and the Afghan civil war.

The Centers for Disease Control and Prevention says 2012's outbreak of West Nile virus is on track to be the worst in U.S. history. The mayor of Dallas recently authorized an aerial spraying program to kill the mosquitoes that carry the virus, which provoked protest from area residents.

The Paralympic Games are the second largest sporting event in the world, after the Olympics, and begin August 29th. 4,000 elite disabled athletes will compete in 20 sports. Many of the sports are familiar, but others — like boccia and goalball — are unique to the Paralympics.

This weekend, a court in Moscow sentenced three women from a previously obscure punk band guilty of hooliganism. They got two years in prison and made Pussy Riot an international sensation. In the Washington Post today, columnist Anne Applebaum writes that for all the attention paid to the case, Madonna's was by far the most damaging, not because she's a serious political figure, but because she isn't.
