Yonath, 70, is the fourth woman to win the Nobel chemistry prize and the first since 1964, when Dorothy Crowfoot Hodgkin of Britain received the award. "I'm really, really happy," Yonath said. "I thought it was wonderful when the discovery came. It was a series of discoveries. ... We still don't know every, everything, but we progressed a lot."
