Shortly after last year’s Olympics, the urine samples of some six dozen athletes came back with traces of a banned stimulant. Career-altering penalties loomed. But they were avoided thanks to some nimble sleuthing by anti-doping scientists in the U.S. and Germany. The scientists discovered the stimulant could be found in an ingredient present in an over-the-counter sunscreen. (AP Photo/Gregory Bull, File)
