Human mission to Mars faces shortage of radiobiologists

The U.S. goal of a human mission to Mars faces many hurdles, among them a shortage of space radiobiologists. It’s a shortage NASA addressed in part with its first space radiation summer school, held last month at Brookhaven National Laboratory. Until recently, space radiobiology, a hybrid mix of biology and physics, was considered a dead-end field. But now, helped by new discoveries and new facilities, the research has gotten more attention.
