Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get.

Colonies of bacteria grown aboard the Space Shuttle Atlantis behaved in ways never before observed on Earth, according to a new NASA-funded study from Rensselaer Polytechnic Institute, Troy, New York. Recent findings provide important evidence of spaceflight's effect on the behavior of bacterial communities, and represent a key step toward understanding and mitigating the risk these bacteria may pose to astronauts during long-term space missions.
