Robert Crane Dies

Robert Crane — the Washington University of St. Louis biochemist who helped discover how the body absorbs salt and sugar — has died, reports the Chronicle of Higher Education. He was 90. Crane's work helped provide a scientific basis of oral-rehydration therapy, which is used to treat cholera, the Chronicle adds. In an interview given several months before his death to the American Physiological Society, Crane had this advice for young scientists: "Work hard, focus, don't fear making a mistake, pay attention to the possibility that you could be right, although most frequently you'll be wrong, and for that, you'll need a lot of resistance to frustration."
