It's well known that scientists commonly look to nature to create super-strong materials. Diamond powder, for instance, is used for oil drills and road machinery, and soon spider silk could be use in bullet-proof vests.

Recently, researchers have turned their attention to the fang-like jaws of marine worms, which they believe could lead to a new cutting-edge, lightweight material so strong that it could be used for construction and as repair material for spacecraft and airplanes.
