Today (05/31/00), I heard a news commentator on CNBC state that a 
publication (perhaps "Science Today") had published an article claiming 
that the speed of light was "faster" (than c) when the beam was passed 
through a Cesium cloud.  The commentator stated that the article said that 
the light beam "exited the cloud before it entered."  I was wondering if 
you could provide ANY information regarding either the article or the 
experiment yielding these reults.  Thanks very much!
