When it comes to climate change, you've heard of melting icecaps and rising sea levels, but just how high will the sea levels rise in 20, 30 or 100 years? Will it be enough to notice the difference? New research now says the oceans will swallow up more and more of our coastline, rising not just inches but feet according to two new reports released by the National Research Council and the U.S. Geological Survey.
This is SCIENCE FRIDAY. I'm Ira Flatow. Your telephone is a computer, really. Your microwave, it's got a computer in it. Your television, it's got a computer there. Even, of course, your computer has a computer. Your iPhone, your cellphone. Everything - just about everything in electronics these days has a computer, and they all work the same way like a Turing machine. Decades before your PC, your Mac or your Commodore, Alan Turing was designing a machine which could calculate almost anything: a universal computer.
This is SCIENCE FRIDAY; I'm Ira Flatow. Imagine walking through Times Square, and every step you take it converted into a tiny electric current by the special pavement underfoot. Now multiply by the third of a million people who walk through Times Square on any given day. Wow, it could be a pretty awesome source of renewable energy, right, perhaps enough to power all those neon lights and flashing billboards.
Peter Parker and Gwen Stacy hit the big screen again next week. The new movie "The Amazing Spider-Man" opens on July 3rd. And once you accept the premise that a man can get super spidey skills from a radioactive - sorry to laugh - spider bite, well, you know, just like Johnny Carson used to say, you buy the premise, you buy the bit.
Does Bruce Springsteen's broad appeal lie in the conviction with which he conjures up a New Jersey working-class identity, one with hard boundaries, as David Brooks writes in The New York Times? Politicians could learn from the Boss, offers Brooks: "Don't pretend you're a member of every community you visit. Don't try to be citizens of some artificial globalized community. Go deeper into your own tradition. ... People will come."

It's summer. School's out and college kids are resting their brains.
Except for the thousands who aren't — including students avidly engaged in science, all around the world.
In Uganda, at the Budongo Conservation Field Station, a young male chimpanzee called Zed tries to impress a female named Kumi. He shreds a leaf, he hits the ground, he moves through the repertoire of tried-and-true chimpanzee tactics for luring a mate. No luck; for a good while, Kumi remains impassive.

In the chicken and pork industries, nearly every aspect of the animals' raising has long been controlled by just a handful of agriculture conglomerates. But the cattle industry is still populated by mom-and-pop operations, at least at the calf-raising level.
Often, the familiar hides the deepest mysteries. This is certainly the case with light, one of the take-it-for-granted physical phenomena that surrounds us in everyday life. We wake up to it, we turn it on and off, rarely thinking of what it really is. A good thing, for even the greatest physicists pause before talking about the nature of light.
