Glowing, Blinking Bacteria Reveal How Cells Synchronize Biological Clocks
At right, periodic pulses of arabinose (in red) act like day and night cycles to simulate how the blinking bacteria synchronize their biological clocks. At left, a simulation of bacteria in constant darkness reveals how the blinking bacteria are unable to synchronize their biological clocks. The in-phase and out-of-phase oscillations of the biological clocks are shown by the bottom two graphs. Credit: UC San Diego
