And Bone Is Born ...
A U.K. company, RegenTec, is refining a white powder -- known as Injectable Bone and pictured here -- designed to seal broken bones together in minutes. At room temperature, it is an inert white powder. Once injected into a break site with a needle stick, however, the body's higher temperature causes the two materials to fuse together in a hard, spongy mass much like living bone. | Discovery News Video
