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.
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. Other groups have made light-emitting devices, but this was the first practical one that could make light that a person could see, rather than invisible infrared light.
Curiosity scooped its first sample of Martian soil on Oct. 7, but activities were halted after a small, bright object — which NASA now says is likely a piece of plastic from the rover — was spotted on the ground. Mike Watkins, Curiosity's mission manager, provides an update.
