How does body temperature reset the biological clock?
Numerous processes in our body fluctuate in a regular pattern during the day. These circadian (or daily) variations can be driven by local oscillators present within our cells or by systemic signals controlled by the master ...
Temperature rhythms keep body clocks in sync, researchers find
Researchers at UT Southwestern Medical Center have found that fluctuations in internal body temperature regulate the body's circadian rhythm, the 24-hour cycle that controls metabolism, sleep and other bodily functions.
New chemical may lead to jet lag drug
Body clock regulates metabolism
(PhysOrg.com) -- UC Irvine researchers have discovered that circadian rhythms - our own body clock - regulate energy levels in cells. The findings have far-reaching implications, from providing greater insights ...
To sleep or not to sleep? Math software to help plan astronaut, shift worker schedules
(April 14, 2010) - Shifting work schedules can wreak havoc on a person's ability to get enough sleep, resulting in poor performance on the job.
Keeping time: Circadian clocks
Our planet was revolving on its axis, turning night into day every 24 hours, for 4.5 billion years - long before any form of life existed here. About a billion years later, the very first simple bacterial ...
Fruit flies reveal surprising new evolutionary link for studying human health
New research reveals that fruit flies and mammals may share a surprising evolutionary link in how they control body temperature through circadian rhythm, unlocking new ways to study the insects as models of ...
Breast Cancer and Body Rhythms
Could working the night shift alter a woman's body clock enough to cause breast cancer?
Body clock drugs could ease psychiatric disorders and jet lag
UK researchers have successfully used a drug to reset and restart the natural 24 hour body clock of mice in the lab. The ability to do this in a mammal opens up the possibility of dealing with a range of human difficulties ...
Brain's clock influenced by senses
Humans use their senses to help keep track of short intervals of time according to new research, which suggests that our perception of time is not maintained by an internal body clock alone.
Newly discovered molecule essential to resetting 'body clocks'
(PhysOrg.com) -- Research has shown that light is the key to getting our 'body clocks' back in sync and now a new study exploring the resynchronisation mechanism in insects has discovered a molecule essential ...
Russian spacecraft delivers new crew to ISS
A spacecraft carrying two Russians and an American docked Wednesday with the International Space Station in the first Russian manned mission for five months after a spate of technical failures.
Ease into daylight savings time
With winter now behind us and the longer days of summer looming comes the annual switch to daylight saving time.
Melatonin, a hormone segregated by human body, regulates sleep better than somniferous
Melatonin, a natural hormone segregated by the own human body, is an excellent sleep regulator expected to replace somniferous, which are much more aggressive, to correct the sleep/wakefulness pace when human biological clock ...
