The activation and inactivation mechanisms of a key protein involved in the circadian clock system of cyanobacteria -- an important organism in the evolution of such internal clocks -- have long ...

Research into genetic mutations that affect circadian rhythms offers new insight into the rest-wake cycle and provides a new model for investigating human disease and ultimately developing medical ...

Living organisms possess an internal biological cycle known as the circadian clock, enabling them to adapt to environmental changes arising from the Earth’s rotation. This internal clock regulates ...

Every cell in the human body operates on an intricate internal schedule, governed by circadian rhythms that synchronize our biological processes with the 24-hour cycle of day and night. Coordinated by ...

It has been known for years that the brains of many organisms incorporate a "circadian clock" — a biological time-keeping mechanism that connects the body's rhythms to external light levels. The clock ...

A maximum of six centimeters long and weighing two grams: Despite its inconspicuous appearance, Antarctic krill plays a central role for life in the Southern Ocean. Individually, Antarctic krill ...

In a pair of experimental and theoretical papers published in Nature Communications and eLife, University of Chicago scientists studied the mechanisms of two kinds of circadian “clocks” that nearly ...

New research in mice has found that the immune system does not respond equally well at different times of the day. This suggests that the body clock may influence mechanisms related to immunity. Share ...
