Multivitamins have ignited a fierce scientific debate over whether nutritional supplements are beneficial to our health or a multi-billion-dollar racket. A long-term randomized controlled trial in the ...

Boyajian's Star has baffled astronomers for a decade with its chaotic brightness dips. A new Bayesian analysis by IAC ...

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 ...

New research discovered that too little or too much sleep can be detrimental to your long-term health. Instead, scientists ...

If you’re interested in completely reworking the body’s internal clock, you might be intrigued by medicinal fungi with transformative effects. If you’re just looking to tweak it, you may not need to ...

Clock genes are a set of genes known to contribute to the regulation of the human body's internal 24-hour cycle, also known as the circadian rhythm. One of these genes is the so-called CLOCK gene, a ...

A study led by the University of Oxford has identified a surprising source of entropy in quantum timekeeping—the act of measurement itself. In a study published in Physical Review Letters, scientists ...

Cells with a functioning molecular clock are better able to adapt to changes in glucose supply and can recover faster from long-term starvation, according to a study published today in eLife. The ...

Peak workout performance depends on sleep, nutrition, and increasingly, what time of day we work out. As scientists do more research on our internal clocks, we’re learning that timing a workout to ...

Scientists used quantumly entangled two optical atomic clocks at a distance of two meters, reports a new study. The achievement opens the door to probing fundamental reality on a deep level. It’s hard ...

If you’re hitting the snooze button in the mornings, it might be because you’re chronically tired. A study published in the journal Sleep suggests that those who use an alarm clock to wake up are more ...

Daily cycles in virtually every aspect of our physiology are driven by biological clocks (also called circadian clocks) in our cells. The cyclical interactions of clock proteins keep the biological ...
