This illustration shows how the components of the cyanobacterial circadian clock interact in a 24-hour cycle. (Image credit: Andy LiWang) Daily cycles in virtually every aspect of our physiology are ...

To better understand the circadian clock in modern-day cyanobacteria, a Japanese research team has studied ancient timekeeping systems. They examined the oscillation of the clock proteins KaiA, KaiB, ...

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 ...

Plants harness an internal circadian clock to synchronise myriad physiological processes with the daily cycle of light and darkness. At its core, this system comprises interlocking ...

Circadian clocks, which drive circadian rhythms, are entwined with many essential systems in living things including plants, fungi, insects, and even humans. Because of this, disruptions to our ...

Daily cycles in virtually every aspect of our physiology are driven by biological (or circadian) clocks in our cells. A team of interdisciplinary scientists has now reconstituted the circadian clock ...

Structural studies revealed the role of protein interactions in cyanobacterial circadian rhythms. What does this tell us about biological clocks in complex organisms? Model of rhythmic interactions of ...

In a study published May 28 in the journal npj Digital Medicine, University of Michigan researchers found that individuals with stronger seasonal sensitivity, which determines how a person’s body ...

Chemical oscillators have long been studied by engineers and scientists. The researchers who discovered the chemical oscillator that controls the human circadian rhythm — responsible for our bodies’ ...

The story I’m about to tell happened a few years ago. An older neighbor, whom I'll call "Anna," had spent a few years with wildly irregular sleeping habits. She asked me to set the digital clock on a ...

As our bodies and minds continue to adjust to the recent time change, debates continue around society about whether to make daylight saving time a permanent fixture, eliminate it or stay with the ...
