SignOnSanDiego.com > News > Science/Health -- Scientists freeze pulse of light, for an instant: "Physicists say they have brought light to a complete halt for a fraction of a second and then sent it on its way, an achievement that could someday help scientists develop powerful new computers.
The research differs from work published in 2001 that was hailed at the time as having brought light to standstill.
In that work, light pulses were technically 'stored' briefly when individual particles of light, or photons, were taken up by atoms in a gas."
Hmm, more reading necessary. /. has good coverage.
