Disruption of circadian rhythm linked to breast cancer, shows study

The disruption of a person's circadian rhythm—their 24-hour biological clock—has been linked to an increased risk of breast cancer, according to new University of Georgia research. The culprit, in this study in particular, is artificial light.

Space missions affect sleep patterns in astronauts

The most comprehensive study of sleep patterns during spaceflight has just been published and confirms that astronauts suffer considerable sleep deficiency during both pre-mission training and spaceflight.

Altering the circadian rhythm: an interview with Dr. Doug Kojetin, The Scripps Research Institute

The circadian rhythm is affected by many different stimuli—such as sleep and light, which are the most broadly appreciated ways—but also eating— all of which can modulate, or change, important processes in our bodies such as temperature, production of hormones or other signalling small molecules, cellular regeneration, and others.

Scientists study how artificial light influences biological clock

Researchers at Inserm, led by Claude Gronfier (Inserm Unit 846: Stem Cell and Brain Institute), have, for the first time, conducted a study under real conditions on the body clocks of members of the international polar research station Concordia.

Lipoic acid appears to reset and synchronize circadian rhythms

Researchers have discovered a possible explanation for the surprisingly large range of biological effects that are linked to a micronutrient called lipoic acid: It appears to reset and synchronize circadian rhythms, or the "biological clock" found in most life forms.

Scientists discover new role for pair of compounds which alter circadian rhythm

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have discovered a surprising new role for a pair of compounds—which have the potential to alter circadian rhythm, the complex physiological process that responds to a 24-hour cycle of light and dark and is present in most living things.

Researchers examine link between full moon and sleep

A Swiss research study conducted last year showed that the full moon affects sleep. The findings demonstrated that people average 20 minutes less sleep, take five minutes longer to fall asleep and experience 30 minutes more of REM sleep, during which most dreaming is believed to occur.

Protein complex structure that plays an important role in regulating circadian rhythm identified

Structural biologists have made important progress towards better understanding the functioning of the circadian clock. The circadian or inner clock coordinates the sleep-wake rhythm and many other body processes that regulate, for example, metabolism, blood pressure, and the immune system.

New high-throughput method offers rapid whole-brain imaging at single cell resolution

A major challenge of systems biology is understanding how phenomena at the cellular scale correlate with activity at the organism level. A concerted effort has been made especially in the brain, as scientists are aiming to clarify how neural activity is translated into consciousness and other complex brain activities.
