A new optical effect has been created in a London laboratory that means solid objects such as walls could one day be rendered transparent. Researchers from Imperial College London and the University of Neuchatel, Switzerland, have pioneered the technique which could be used to see through rubble at earthquake sites, or look at parts of the body obscured by bone. The effect is based on the development of a new material that exploits the way atoms in matter move, to make them interact with a laser beam in an entirely new way — via Warren Ellis
