Disruptions to our circadian clocks—the internal molecular timekeepers "ticking" in nearly every cell of our body throughout ...

New research has uncovered how a simple circadian clock network demonstrates advanced noise-filtering capabilities, enhancing our understanding of how biological circuits maintain accuracy in dynamic ...

A night-shift worker finishes at dawn. Their phone says Tuesday, but their body feels like it's Monday. The body's internal ...

Researchers have advanced our understanding of the circadian clock, the biological cycle that synchronizes with light-dark exposure. They recently developed a method to study how the circadian clock ...

Two complementary research articles reveal that central and peripheral circadian clocks coordinate to regulate the daily activity of skin and muscles. The coordination between the two clocks (central ...

Circadian rhythms are the cycles that tell the body when to sleep, wake, and eat—the biological and psychological processes that oscillate in predictable patterns each day. This internal clock is ...

Neutrophils cause time-of-day–dependent collateral tissue damage after sterile injury through an intrinsic circadian program.

While bright light helps us see better, our eyes need darkness for better vision. Light breaks down the sensitive machinery of our eyes every day, and during the darkness of night, key pieces are ...

The rituals and habits we cultivate during the day can impact sleep health. The months leading up to December often feel like a race. Regardless of the industry you might be working in, the ...

To say “I’m not a morning person” would be an understatement. Not only is it hard for me to be useful in the first hour (or so) of being awake, but it’s hard for me to wake up. I mean, really hard.
