This is SCIENCE FRIDAY. I'm Ira Flatow. Fifty years ago this week, a team of researchers at General Electric created something new: a solid-state device that could emit visible red light without getting hot like a light bulb.

For nearly a decade, scientists and Northwest tribes in Washington state fought bitterly over whether to bury or study the 9,500-year-old bones known as Kennewick Man. Scientists won the battle, and now, after years of careful examination, they're releasing some of their findings.

This is SCIENCE FRIDAY; I'm Ira Flatow. The 2012 Nobel Prizes were announced this week in Stockholm, and groundbreaking research on stem cells, cloning, cell receptors and quantum optics, yeah, claimed the honors this year. The physics prize was awarded to French physicist Serge Haroche and American David Wineland of the National Institute of Standards and Technology and the University of Colorado.
Ben Affleck's Argo is two-two-TWO movies in one, and while neither is especially original, by merging them Affleck pulls off a coup. First, he gives you espionage with the You Are There zing of a documentary. Then he serves up broad showbiz satire. For his final feat, he blends the two into a pulse-pounding nail-biter of a climax.
