A ticking clock in the belly warned Captain Hook of a crocodile’s approach. A different kind of internal clock in gut bacteria may one day prove just as helpful.
Researchers have transplanted a simple circadian clock from cyanobacteria — also known as blue-green algae — into E. coli. The feat, researchers report June 12 in Science Advances, is a first step toward creating organisms that may stave off jet lag or even make drugs on a schedule.
