A time-lapse movie of a WT cyanobacteria strain in a Green Mother Machine. The strain expresses a pkaiBC:eYFP:fsLVA transcriptional reporter (shown in green), which displays circadian oscillations.

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 ...

(NEXSTAR) – If you already dread changing the clocks, a new study from sleep researchers at Stanford Medicine may have you researching a move to Hawaii or Arizona, the two states that do not observe ...

A large England study found fewer NHS visits for sleep, heart, and mental health issues after clocks moved back in autumn.

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 ...

Time moves differently on Mars — not in the Tibetan philosophy sense of the word, but in a measurable, physics-will-ruin-your-mission kind of way that's giving NASA engineers a real headache. As the ...

Muscle cells contain their own circadian clocks and disrupting them with shift work can have a profound impact on aging, according to the results of a preclinical study carried out by Jeffrey Kelu, ...

Researchers from the Institute for Molecular Science (IMS)/SOKENDAI and Kyushu University have uncovered the molecular mechanism that drives the "ticking" of the circadian clock in cyanobacteria.

Titled “Role of Cardiac Clock Misalignment in Promoting Arrhythmias in Swine and Donor Human Hearts,” the five-year, $3.4 million study is funded by a R01 grant from the National Heart, Lung and Blood ...

Graphic illustrating the difference in energy between running a quantum clock (left: a single electron hopping between two nanoscale regions) and reading the ticks of the clock (right). The energy ...
