Researchers Study Vital ‘On/Off Switches’ That Control When Bacteria Turn Deadly

No matter how many times it’s demonstrated, it’s still hard to envision bacteria as social, communicating creatures. But by using a signaling system called “quorum sensing,” these single-celled organisms radically alter their behavior to suit their population. Helen Blackwell, a professor of chemistry at the University of Wisconsin-Madison, has been making artificial compounds that mimic the natural quorum-sensing signals.
