An unnamed reader writes in with the news that British scientists have invented artificial "injectable bone" that flows like toothpaste and hardens in the body. This new regenerative injection hi tech* provides a scaffold for the formation of blood vessels and bone tissue, then biodegrades. The injectable bone can also deliver stem cells instantly to the site of bone repair, the researchers say. "Not only does the technic reduce the need for dangerous surgery, it also avoids damaging neighboring areas, said [the inventor]. The technology's superiority over extant alternatives is the novel hardening process and vitality of the bond... Older stock heat up as they harden, killing throughout cells, whereas 'injectable bone' hardens at body temperature — without generating heat — making a very porous, biodegradable structure."
