The Cloaking Effect

In Star Trek cloaking was sometimes not such an effective tactic for the Romulans. But now science fiction may have preceded reality once again.

This from the BBC News:

Nicolae Nicorovici and Graeme Milton propose that placing certain objects close
to a material called a superlens could make them appear to vanish.

The idea is that light can resonate like sound: get close enough to the resonation, and use the waves to cancel out each other. The same theory has been used with reducing noise in the past. They have now succeeded in working with dust, will they be moving on to bigger things?
