The circadian clock evolved in diverse organisms to integrate external environmental
changes and internal physiology. The clock endows the host with temporal precision and …

To accommodate daily recurring environmental changes, animals show cyclic variations in
behaviour and physiology, which include prominent behavioural states such as sleep–wake …

Circadian clocks are endogenous oscillators that control 24-hour physiological and
behavioural processes in organisms. These cell-autonomous clocks are composed of a …

Environmental light cycles entrain circadian feeding behaviors in animals that produce
rhythms in exposure to foodborne bacteria. Here, we show that the intestinal microbiota …

The Earth turns on its axis every 24 h; almost all life on the planet has a mechanism—
circadian rhythmicity—to anticipate the daily changes caused by this rotation. The molecular …

The mammalian circadian clock has evolved as an adaptation to the 24-h light/darkness
cycle on earth. Maintaining cellular activities in synchrony with the activities of the organism …

The circadian clock is a complex cellular mechanism that, through the control of diverse
metabolic and gene expression pathways, governs a large array of cyclic physiological …

Most animals alternate periods of feeding with periods of fasting often coinciding with sleep.
Upon> 24 hr of fasting, humans, rodents, and other mammals enter alternative metabolic …

The circadian timing system governs daily biological rhythms, synchronising physiology and
behaviour to the temporal world. External time cues, including the light‐dark cycle and …

Circadian rhythms evolved through adaptation to daily light/dark changes in the
environment; they are believed to be regulated by the core circadian clock interlocking …
