Why Let Conventional Physics Get in the Way of a Good Time in the Lab?

Physicists at the University of Rochester have reduced the speed of light to approximately 1/300th of its normal speed. The scientists filled a chamber with cesium gas, heated to 212 F. When light was beamed through the chamber, it slowed down from 300 million m/s to about 1 million m/s. When the light exited on the other side, it returned to its normal velocity and retained its phase and frequency. Ideally, this technology can be applied to information transmission; conventional methods are reaching their physical limits.

(As of today, Physical Review Letters has not published the paper online. More to come when it does.)
