Butterflies have evolved a unique mechanism to create a dazzling display of colour which puts physicists in the shade. Modern light emitting devices have traditionally been inefficient because most of the light created can't escape, but now in a paper published in Science, University of Exeter scientists have discovered the butterfly has been doing what physics couldn't, for more than 30 million years.

Very cool stuff.

just imagine what we'll be doing in 30 million years... if we don't vaporize ourselves in conflict.
