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 ...

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 ...

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 ...

A new study of molecular interactions central to the functioning of biological clocks explains how certain mutations can shorten clock timing, making some people extreme “morning larks” because their ...
