Researchers from Tokyo Metropolitan University have used fruit flies to study how daily eating patterns are regulated. They found that the quasimodo (qsm) gene helped sync feeding to light/dark cycles, but not in constant ...

All animals have an internal clock called a circadian clock, which is regulated by cues from their environment—but animals in zoos can be exposed to very different cues from animals in the wild.

A circadian rhythm is a roughly-24-hour cycle in the biochemical, physiological or behavioral processes of living entities, including plants, animals, fungi and cyanobacteria (see bacterial circadian rhythms). The term "circadian", coined by Franz Halberg, comes from the Latin circa, "around," and diem or dies, "day", meaning literally "approximately one day." The formal study of biological temporal rhythms such as daily, tidal, weekly, seasonal, and annual rhythms, is called chronobiology.
Circadian rhythms are endogenously generated, and can be entrained by external cues, called Zeitgebers, the primary one of which is daylight. These rhythms allow organisms to anticipate and prepare for precise and regular environmental changes.
