Many things would be difficult about conducting a manned mission to Mars, from designing a spacecraft that could make the 34-million-mile journey, to stocking and fueling it, to keeping its astronauts from getting flabby and bored. On Friday, researchers shed light on another potential hurdle: figuring out a way to protect travelers' brains from the damaging effects of cosmic rays in outer space. When UC Irvine neuroscientist Charles Limoli and colleagues exposed mice to radiation similar to that astronauts would encounter far beyond Earth, the animals experienced changes in their brains that impaired their performance on tests of learning and memory, the team reported...
