Nobel winner reunited with sister lost in WWII

After winning the Nobel Prize for medicine, University of Utah geneticist Mario Capecchi learned he has a younger sister. Capecchi and half-sister Marlene Bonelli met last month in northern Italy. They were too young to remember when they were separated in the early days of World War II, and Bonelli had long believed that Capecchi and their mother had died in the war.
