Growing Bones
Abstract:
Every year, almost 500,000 people go into America's hospitals to receive a total knee replacement, according to the National Center for Health Statistics. For some, it's a painful procedure with significant recovery time.
Materials scientist Robert Haddon from the University of California, Riverside thinks there may be another solution. He has been working with carbon nanotubes, which are so small, they're 100,000 times finer than a human hair. He hopes that one day doctors might be able to inject these nanotubes into a knee, or another injury, where they would encourage damaged or broken bones to regrow. (with Video)
