Circadian surprise: A heat sensor for body-clock synchronization
New research on the fruit-fly brain points to a possible mechanism by which temperature influences the body clock, according to scientists from Queen Mary, University of London.   view more (2009-10-30)

Researchers propose new molecule to explain circadian clock
The internal clock in living beings that regulates sleeping and waking patterns -- usually called the circadian clock -- has often befuddled scientists due to its mysterious time delays. Molecular interactions that regulate the circadian clock happen within milliseconds, yet the body clock resets about every 24 hours.   view more (2007-08-28)

Flowers to Order
How do growers ensure their Poinsettias are ready for Christmas or their roses for Valentine’s Day? Professor Andrew Millar (Warwick University) will present current work on Thursday 3 April (in session P9.9) which could help breeders to schedule their crops more accurately. Like most organisms, plants possess a ‘clock’ which... view more... (2003-03-31)

Faulty body clock may make kids bipolar
Malfunctioning circadian clock genes may be responsible for bipolar disorder in children. Researchers writing in the open access journal BMC Psychiatry found four versions of the regulatory gene RORB that were associated with pediatric bipolar disorder.   view more (2009-11-12)

Plants' internal clock can improve climate-change models
The ability of plants to tell the time, a mechanism common to all living beings, enables them to survive, grow and reproduce.   view more (2009-07-06)

Study led by Scripps Research scientist reveals little-known cell networks vital to circadian rhythm
Circadian rhythm is the basic 24-hour cycle that involves various behaviors, including sleeping and eating, in all living organisms. In mammals, the circadian clock is organized hierarchically in a series of multiple oscillators.   view more (2007-05-04)

Clock molecule's sensitivity to lithium sheds light on bipolar disorder
Researchers at the University of Pennsylvania School of Medicine discovered that a key receptor protein is a critical component of the internal molecular clock in mammals. What's more, this molecule -called Rev-erb- is sensitive to lithium and may help shed light on circadian rhythm disorders, including bipolar disorder.   view more (2006-02-17)

Novel connection found between biological clock and cancer
Dartmouth Medical School geneticists have discovered that DNA damage resets the cellular circadian clock, suggesting links among circadian timing, the cycle of cell division, and the propensity for cancer.   view more (2006-06-30)

Circadian rhythm-metabolism link discovered
UC Irvine researchers have found a molecular link between circadian rhythms - our own body clock - and metabolism. The discovery reveals new possibilities for the treatment of diabetes, obesity and other related diseases.   view more (2008-07-25)

Gene controlling circadian rhythms linked to drug addiction, UT Southwestern researchers find
The gene that regulates the body's main biological clocks also may play a pivotal role in drug addiction, researchers at UT Southwestern Medical Center have found.   view more (2005-06-14)

Phase of clock gene expression in human leukocytes correlates with habitual sleep timing
The phase of clock gene expression in leukocytes, assessed in the absence of the masking effects of light-dark and sleep-wake cycles, correlates with habitual sleep timing, according to a study published in the May 1 issue of the journal SLEEP.   view more (2008-05-01)

Another reason to avoid high-fat diet -- it can disrupt our biological clock
Indulgence in a high-fat diet can not only lead to overweight because of excessive calorie intake, but also can affect the balance of circadian rhythms - everyone's 24-hour biological clock, Hebrew University of Jerusalem researchers have shown.   view more (2008-12-29)

Resistance exercise resets the body clock
Resistance exercise may directly reset the body clocks in skeletal muscle, according to research published in Genome Biology this week. This result may partly explain how exercising early in the day helps jet-lagged bodies readjust to their new time zone. Many processes in the body vary in a 24-hour rhythm called the circadian rhythm. These... view more... (2003-09-24)

More evidence mammals, fruit flies share make-up on function of biological clocks
A study by researchers at New York University and the University of London offers additional evidence that mammals and fruit flies share a common genetic makeup that determines the function of their internal biological clocks. The study appears in the latest issue of Current Biology.   view more (2006-03-07)

Mouse vision has a rhythm all its own
In the eyes of mammals, visual information is processed on a daily schedule set within the eyes themselves-not one dictated by the brain, according to a new report in the August 24 issue of the journal Cell, a publication of Cell Press.   view more (2007-08-24)

Genetic pathway responsible for link between body clock disturbance and worsening arthritis
The genes that regulate human circadian rhythm, or 'the body clock', are significantly disturbed in individuals with arthritis.   view more (2009-06-11)

Feeling sleepy is all in your genes
Genes responsible for our 24 hour body clock influence not only the timing of sleep, but also appear to be central to the actual restorative process of sleep, according to research published in the online open access journal BMC Neuroscience.   view more (2007-10-18)

NYU dental professor discovers biological clock
Why do rats live faster and die younger than humans? A newly discovered biological clock provides tantalizing clues.   view more (2008-04-07)

Biological Timekeeper Studies Reveal New Temperature Regulator and Track Clock Protein across a Day
Dartmouth Medical School geneticists have made new inroads into understanding the regulatory circuitry of the biological clock that synchronizes the ebb and flow of daily activities.   view more (2009-05-18)

Simplest circadian clocks operate via orderly phosphate transfers
Researchers at Harvard University and the Howard Hughes Medical Institute have found that a simple circadian clock found in some bacteria operates by the rhythmic addition and subtraction of phosphate groups at two key locations on a single protein.   view more (2007-10-05)
