Scientists have succeeded for the first time in extinguishing light in one spot and then making it reapear somewhere else. Physicist Stephen Barlett said the research was an important step to developing light-based technologies.
Nothing travels faster than light, but scientists want to slow it down so they can better manipulate it!Dr barlett said that light can be extinguished in one condensate and revived in other because at quantum level, atoms of the same kind are indistinguishable, no matter how far apart they are."You have to think of the two condensates as one condensate in two different places!"
Superfast quantum computers based on light would be able to handle huge ammounts of information, for example to better model climate change.

Unfortunately I don't have a link either, but I did hear about this research last week, and it seems fascinating. If they find reliable ways of manipulating light, we can have much faster means of communication; this is already used somewhat in fiber optics, but in a very clunky way.
(Just to expand on a line from the original post: nothing can travel faster than the speed of light _in a vacuum_. In other mediums, even air, light slows down depending on what it is passing through).

I cant post links here yet so try to search in yahoo with light scientists

Its gr8 step from the view of scientist efforts. but more really step when he is succeded in making light inside the human being. wht i feel is make minimum interference of human in wht nature is doing, coz whn we human being not having the understanding of nature and not having the control of that thn it should not do that much interference coz wth not knwing hw to stop, never start that experiment. what is good if he remove the cause of climate change, i.e more cities, more pollution, decrease of trees.. isn't it?
It is wht i feel, may be u feel different frm me.

I would of thought you would be able to use this towards space travel, I'm no scientist by any means but it kinda makes sense to me.
