Look at This: A Touch of Gold for the World's Most Powerful Telescope

Golden and gleaming, this convex mirror arrived last week at the Goddard Space Flight Center in Greenbelt, Md., where it will be mounted on the much-anticipated Webb telescope. When the telescope is up and running, sometime later this decade, the Webb will take the title of the most powerful space telescope ever built, ousting even the Hubble. The Boulder-built mirror's color comes from a microscopic layer of gold, 1,000 times thinner than a human hair. The gold will help the telescope better r

Supersymmetry squeezed as Large Hadron Collider spots ultra rare particle decay

Scientists at the Large Hadron Collider (LHC) at CERN, near Geneva, have spotted one of the rarest particle decays ever seen in nature. The result is very damaging to new theories like the extremely popular Supersymmetry.<img src="http://feeds.feedburner.com/~r/sciencedaily/matter_energy/physics/~4/8uA... height="1" width="1"/>

Powering lasers through heat

In micro electronics heat often causes problems and engineers have to put a lot of technical effort into cooling, for example micro chips, to dissipate heat that is generated during operation. Physicists have now suggested a concept for a laser that could be powered by heat. This idea may open a completely new way for cooling microchips.<img src="http://feeds.feedburner.com/~r/sciencedaily/matter_energy/physics/~4/sBU... height="1" width="1"/>

Confining supersymmetry: LHCb presents evidence of rare B decay

Today, at the Hadron Collider Physics Symposium in Kyoto, the LHCb collaboration has presented the evidence of a very rare B decay, the rarest ever seen. The result further shrinks the region in which scientists can still look for supersymmetry.
