Symbiotic bacteria program daily rhythms in squid using light and chemicals

Glowing bacteria inside squid use light and chemical signals to control circadian-like rhythms in the animals, according to a new study. The results of the study show that, in addition to acting as a built-in lamp, the bacteria also control when the squid expresses a gene that entrains, or synchronizes, circadian rhythms in animals.
