Twenty-five years ago this month, researchers first identified buckminsterfullerenes -- chemical structures shaped like tiny carbon soccer balls. The scientists had discovered an new form of carbon, separate from graphite or diamond. The work went on to earn Robert Curl, Richard Smalley, and Harold Kroto the Nobel Prize. We'll talk with Dr. Kroto about the discovery and what's been learned about fullerenes since then.
