University of Southern California professor Arieh Warshel (C) talks on the phone to Israeli President Shimon Peres as he sits between his wife Tami Warshel (R) and daughter Yael Warshel after hearing he won the Nobel chemistry prize in Los Angeles, California October 9, 2013. Warshel, a U.S. and Israel citizen, won the Nobel chemistry prize with U.S. scientists Martin Karplus and Michael Levitt on Wednesday for pioneering work on computer programs that simulate complex chemical processes and have revolutionised research in areas from drugs to solar energy. The Royal Swedish Academy of Sciences, awarding the prize of 8 million crowns ($1.25 million) to Karplus, Levitt and Warshel, said their work had effectively taken chemistry into cyberspace. Long gone were the days of modelling reactions using plastic balls and sticks. REUTERS/Lucy Nicholson (UNITED STATES - Tags: POLITICS SCIENCE TECHNOLOGY SOCIETY)
