New Nobel Prize Winner In Chemistry Reflects On Win

Three U.S.-based scientists won the Nobel Prize in Chemistry today. Martin Karplus, Michael Levitt and Arieh Warshel met at Harvard in the early 1970s, and it was there that they developed a computer program that brought together classical and quantum physics in order to study molecular reactions.

Their breakthrough allowed scientists to simulate chemical reactions onscreen instead of in the lab, and that's helped increase the speed and sophistication of everything from drug development to solar cell design.

The winners will share a $1.2 million prize.

Co-winner Arieh Warshel, 72, who teaches chemistry at the University of Southern California in Los Angeles, speaks to Here & Now.
