British scientist John Gurdon poses for the media after a news conference in London, Monday, Oct. 8, 2012. Gurdon and a Japanese scientist, Shinya Yamanaka, won the Nobel Prize in physiology or medicine on Monday for discovering that ordinary cells of the body can be reprogrammed into stem cells, which then can turn into any kind of tissue, a discovery that may led to new treatments.
