For example, do the morning cells fire at a different time than the evening cells, or is the distinction between the two cell groups made at the level of output gene expression? Although the core ...

Human life is governed by a circadian rhythm (around 24 hours) that is controlled by a tiny biological clock located in the ...

“The circadian rhythm is generated by the master clock in the brain, an area of 50,000 cells near the hypothalamus [the hormonal control centre of the brain],” says Dr Kat Lederle, founder of ...

Circadian rhythms are the regular, daily cycles of biological processes or activities, including the regular and predictable variation in the levels of many circulating hormones, ions and the ...

Research from the University of California, Irvine has revealed how disruption of the circadian clock, the body's internal, 24-hour biological pacemaker, may accelerate the progression of ...

The coordination between the two clocks (central and peripheral) guarantees 50% of the circadian functions of tissues, ...

Those mesmerizing blue and orange hues in the sky at the start and end of a sunny day might have an essential role in setting humans’ internal clocks. In new research from the University of ...

Your circadian rhythm is part of your body’s internal clock that causes you to feel alert and awake during the daytime and sleepy at night. When your circadian rhythm becomes disrupted ...

Molecular link between circadian clocks and cardiac function: a network of core clock ... Hsieh PN, Zhang L, Jain MK. Coordination of cardiac rhythmic output and circadian metabolic regulation in the ...

We dove into the research on circadian rhythms, and we woke before dawn with 10 different sunrise alarm clocks and two non-clock lighting devices. Our favorite, the Philips SmartSleep Wake-Up ...

"We're mainly concerned with improving people's circadian ... maximum output would be in the 1,000 to 2,000 lux range, because that’s the kind of strong stimulus that will set the clock ...
