It's generally agreed that some kind of microbe will be the first form of life we discover on another planet, moon or other space rock. But hardly anyone thinks we'll find an alien virus, which is weird, given how prolific and successful these biological entities are on Earth. A new study seeks to correct this oversight, calling for an entirely new discipline known as "astrovirology".

A new experiment shows that long-term exposure to microgravity affects bacteria at the genetic level -- conferring reproductive advantages that persist even after the bacteria is reintroduced to unaffected colonies and normal levels of gravity here on Earth.
