Shrimp's eye points way to better DVDs
The amazing eyes of a giant shrimp living on Australia's Great Barrier Reef could hold the key to developing a new type of super high-quality DVD player, British scientists said on Sunday. Mantis shrimps, dubbed "thumb splitters" by divers because of their vicious claws, have the most complex eyes in the animal kingdom. They can see in 12 primary colors, four times as many as humans, and can also detect different kinds of light polarization -- the direction of oscillation in light waves. Now a team at the University of Bristol have shown how the shrimps do it, using remarkable light-sensitive cells that rotate the plane of polarization in light as it travels through the eye.
