supercool

Physics nerds and sci-fi geeks just about everywhere agree: lasers are cool. But cool enough to drop the temperature of a gas by 119 degrees in a matter of seconds? German researchers say so, having made advances on ideas reaching back 30 years but never successfully executed. Bombarding high-pressure gas with a laser, the scientists were able to create a significant cooling effect, shaving the aforementioned 119 degrees from the gas almost instantly by pushing electrons into higher orbit.
