Feed SubscriptionPhysicists cool semiconductor by laser light
Researchers at the Niels Bohr Institute have combined two worlds quantum physics and nano physics, and this has led to the discovery of a new method for laser cooling semiconductor membranes. Semiconductors are vital components in solar cells, LEDs and many other electronics, and the efficient cooling of components is important for future quantum computers and ultrasensitive sensors. The new cooling method works quite paradoxically by heating the material

NASA's Kepler spacecraft is starting to put the pieces together in its search for virtual Earth twins in other planetary systems. Kepler, which launched in 2009 , is on the lookout for planets that are about the size of Earth and have temperate surface conditions. One half of that formula was realized on December 5 when mission scientists announced the discovery of a planet in the so-called habitable zone, called Kepler 22 b , a few times larger than Earth

Harold Kroto won the Nobel Prize in chemistry in 1996 for the discovery of buckminsterfullerene, the soccer ball shaped form of carbon better known as buckyballs. On June 28, he spoke to students [at the Lindau Nobel Laureates meeting] about science as a philosophical construct: "I'm going to talk about what science is because it's a totally misunderstood sort of subject

Dear EarthTalk : Recent news reports have revealed the discovery of previously unknown species inhabiting the deepest parts of our oceans. Is anything being done to protect this habitat before humans have a chance to fish it to death or otherwise destroy it? --Matthew Polk, Gary, Ind.

Theories about Stonehenge have historically tended to regard it as a stand-alone monument. But an increasingly well-supported view holds that Stonehenge was just part of a much larger ceremonial landscape, as this article in the March issue of Scientific American explains
