Help Me Recall...

[Star-struck]

I recall, vaguely, an article I read a year or so ago where some type of experiment was being performed in which light was sent, maybe in a vacuum and the time it took to travel from the source to the target was recorded with syncronized clocks on both ends. It turned out that the light actually somehow reached the target chronologically before it was sent (according to the syncronized clocks). I don't remember the specifics though or what ever came of it. Ring a bell with anyone?

I believe you may be talking about "Gain-Assisted Superluminal Light Propagation."
