Melanopsin plays a key role in the inner workings of the eye

A Brown University team has found that a protein called melanopsin plays a key role in the inner workings of mysterious, spidery cells in the eye called intrinsically photosensitive retinal ganglion cells, or ipRGCs.

Lack of sleep could make you fat

Lack of sleep could make you fat. In an editorial published in the Jan. 10 issue of the Archives of Internal Medicine, two Northwestern University researchers stress the need to better understand the growing epidemic of obesity in the United States by studying how loss of sleep alters the complex metabolic pathways that control appetite, food intake and energy expenditure.

Biological clock affects the patterns of heart-rate control in healthy individuals

In a newly reported, first-ever finding, physicists from Boston University and physiologists from Boston’s Brigham and Women’s Hospital (BWH) have found that the body’s biological clock affects the patterns of heart-rate control in healthy individuals independent of sleep/wake cycle or other behavior influences.

Discovery of gene mutation in fruit flies that alters sensitivity to crack cocaine

Researchers at the University of California, San Francisco (UCSF) and New York University have discovered a gene mutation in fruit flies that alters sensitivity to crack cocaine and also regulates their internal body clock.

Discovery of internal molecular clock that governs the metabolism of sugars and fats within the body

Researchers at the University of Pennsylvania School of Medicine have discovered that components of the internal molecular clock of mammals have an important role in governing the metabolism of sugars and fats within the body.

First study to measure the influence of night-shift work on hormone levels that may affect breast-cancer risk

Three years ago, investigators at Fred Hutchinson Cancer Research Center made headlines nationwide when they published the results of a population-based study that suggested women who work the graveyard shift have an increased risk of breast cancer as opposed to women who work the day shift.

Conference – Childhood leukaemia: incidence, causal mechanisms and prevention

The advances in treating childhood leukaemia over the last forty years have been one of cancer’s outstanding success stories – but the fall in mortality has diverted attention from a rise in incidence, a London conference will hear today (Monday 6 September).

Circadian rhythm research may lead to greater understanding of jet lag and human diseases

Our biological clock, or circadian rhythm, is upset by travelling across time zones, but very soon the body adjusts to the new day/night cycle.

Enzyme activation key to body clock

Feel like time is repeating itself and won’t move on? It could be your internal clock is backpedaling because your PKG-II is out of whack.

Natural hormone called melatonin may guide our sleep patterns

Our general sleep patterns – being sleepy at night and awake during the day – are guided to a great extent by our exposure to light and darkness.

Seasons may be involved in onset of menopause

Research by Hungarian fertility experts published (Thursday 10 June, 2004) in Europe’s leading reproductive medicine journal Human Reproduction, has revealed that the onset of the menopause may not be dictated only by the fact that a woman’s lifetime supply of eggs are running low, but also by changes in the seasons.

People with extremely early or extremely late sleep times may suffer from Circadian Rhythm Sleep Disorder

You probably know "night owls," those people not ready to fall asleep until the wee hours of the morning. And, you may also know "larks," those early risers who wake before the sun comes up and are ready for bed right after dinner. People with extremely early or extremely late sleep times may suffer from Circadian Rhythm Sleep Disorder (CRSD).

Suprachiasmatic nucleus brain tissue sheds light on jet lag

New research led by a University of Washington biologist demonstrates that there are at least two circadian clocks in the mammal brain, one that sticks strictly to an internal schedule and another that can be altered by external influences such as light and dark.
