Small, Small World

Once upon a time, science fiction authors imagined a future in which microscopic machines could repair our bodies at the cellular level. Today, real life scientists believe it may one day be reality. Monday on the Sound of Ideas, we'll talk with local scientists about the latest developments in nanotechnology-the ability to build big things out of little things - really little. Less than 500 times smaller than a human hair. It's a nano-world after all, Monday at nine, on 90.3.
