The scientists at the University of Utah have created a synthetic version of superglue which is produced naturally by the sea worms called Phragmatopoma californica. It might be possible to repair fractured human bones with its help. The worms Phragmatopoma californica inhabit the ocean floor along the California coast. They build “castles” using sand and shattered sea shells, sticking them together with their special glue. The glue hardens in 30 seconds after a worm produces it. Usually these worms build their sandcastles close to each other. This results in big colonies like coral reefs which are also stuck together with the glue. Full story
