Using several imaging techniques, Lawrence Berkeley National Laboratory scientists found that a common soil bacterium stays connected by a network of chain-like membranes. They believe the bacterium uses its network to coordinate social activities-such as evading bacterial enemies and snaring prey-without revealing its location. Even bacteria use social networks
