Designer molecules promise bone repair breakthrough

Newly designed molecules that mimic the nanostructure of bone could lead to a breakthrough in bone repair, a US study suggests. The "designer" molecules hold promise for the development of bone-like material for use in fractures or even for treating bone cancer, say researchers from Northwestern University in Evanston, Illinois, who describe the molecules in Science (November 23). The molecules may also have application in the regeneration of other tissues and organs, they add.
