Harold Kroto, who shared the 1996 Nobel Prize in Chemistry for the discovery of buckminsterfullerene (the molecules commonly known as buckyballs), is a chemist at Florida State University in Tallahassee. His research interests extend from the microworld of nanoparticles to the chemistry of interstellar space. He also campaigns for a new vision of science education, emphasizing the responsibilities that scientists have for cooperating internationally to support efforts aimed at securing a sustainable future for the planet. He spoke on such matters recently at the Euroscience Open Forum 2010 conference in Turin, Italy. Science News editor in chief Tom Siegfried reports excerpts from Kroto’s talk.
