Glowing bacteria that live in the light-generating organs of the tiny bobtail squid play a key role in determining the animal’s circadian rhythms — the natural cycles that help determine when a creature sleeps, wakes, and eats — according to a study published this week in the journal mBio. It’s the first time a symbiotic bacteria has been found to determine the daily habits of its host, and could offer researchers insight into how the bacteria that live in more complicated creatures — including humans — may affect our day to day lives.
