Nobel Peace Prize

Members of the royal family of Sweden—along with 1,300-some guests—honor Nobel laureates at Stockholm City Hall on December 10. The prizes have come under ɿre in recent years for a lack of female honorees, but this year marked the ɿrst time female scientists won in both chemistry and physics. Canada’s Donna Strickland was feted for her work on high-intensity laser pulses, and American Frances Arnold for her work on enzymes.
