Space is a (more dangerous) place

New results of space shuttle research on bacteria has ominous implications. People get weaker in microgravity and have to exercise like crazy just to retain their normal health. But that same microgravity makes Salmonella typhimurium bacteria more virulent. The researchers say the finding might help them concoct new treatments for infections from the bug here on the ground. They probably also better be thinking about this new danger for already-impaired people out in the black.
