"Researchers at Cornell have designed, built and demonstrated the first "cloak" that hides events in time. The process relies on similar methods of distorting electromagnetic fields as invisibility cloaks, but it exploits a time-space duality in electromagnetic theory: diffraction and dispersion of light in space are mathematically equivalent. Scientists have used this theory to create a "time-lens [that] can, for example, magnify or compress in time."

hmmm hiding events in time... i see a big market for college students who wake up next a big girl...

FTFA: Right now, the cloak can only last for 120 nanoseconds, and the theoretical max for the current design measures just microseconds.

Unless that guy is really, uhh, premature, I don't think this will help so much
