New material means 'xray specs' no longer required
I found this on Digg and it looks really cool. Basically, scientists at Imperial College London and a Swiss university have managed to make solids become transparant by disrupting the movement of the electrons by shining light at them. Something like that anyway! At the moment, it only works on a new material under lab conditions, but they hope that eventually it could be used in medical imagery and even network security. Definitely something to watch.
