Optical atomic clock becomes portable
You imagine a clock to be different - yet the optical table with its many complicated set-ups really is one. Optical clocks like the strontium clock in the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig could be the atomic clocks of the future; some of them though are already ten times more precise and stable than the best primary... view more...

U-M discovery about biological clocks overturns long-held theory
University of Michigan mathematicians and their British colleagues say they have identified the signal that the brain sends to the rest of the body to control biological rhythms, a finding that overturns a long-held theory about our internal clock. view more (2009-10-09)
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)
First molecular evidence of body's internal clock in controlling blood pressure
It has been known for decades that heart attacks and strokes occur most frequently in the early-morning hours. Now, researchers at the University of Pennsylvania School of Medicine have provided the first evidence for the role of our body's internal molecular clock in controlling blood pressure and a mechanism by which this occurs. view more (2007-02-20)
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)
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)
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)
UNC study: Tinkering with the circadian clock can suppress cancer growth
Researchers at the University of North Carolina at Chapel Hill have shown that disruption of the circadian clock - the internal time-keeping mechanism that keeps the body running on a 24-hour cycle - can slow the progression of cancer. view more (2009-02-04)
Scientists reveal new pattern in our daily clock
The findings of a study published in Science today turn a long-held theory on circadian rhythms on its head and mean that we may now be able to develop new drugs and approaches to tune the daily clock to treat sleep disorders and to aid recovery from long-distance flights. view more (2009-10-09)
Mercury atomic clock keeps time with record accuracy
An experimental atomic clock based on a single mercury atom is now at least five times more precise than the national standard clock based on a "fountain" of cesium atoms. view more (2006-07-17)
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)
Internal Clock, External Light Regulate Plant Growth
Most plants and animals show changes in activity over a 24-hour cycle. Now, for the first time, researchers have shown how a plant combines signals from its internal clock with those from the environment to show a daily rhythm of growth. view more (2007-07-10)
Molecular 'clock' could predict risk for developing breast cancer
A chemical reaction in genes that control breast cancer provides a molecular clock that could one day help researchers more accurately determine a woman's risk for developing breast cancer and provide a new approach for treatment, UT Southwestern Medical Center researchers have found. view more (2008-05-14)
Individual differences in a clock gene predict decline of performance during sleep deprivation
People are known to differ markedly in their response to sleep deprivation, but the biological underpinnings of these differences have remained difficult to identify. view more (2007-03-09)
Active optical clock
Institute of Quantum Electronics, School of Electronics Engineering and Computer Science, Peking University, has proposed the concept, principles and techniques of active optical clock. view more (2009-04-13)
Scripps research scientists model 3D structures of proteins that control human clock
In an Early Edition issue of The Proceedings of the National Academy of Sciences (PNAS) on April 9, 2009, the researchers report that they have been able to determine the molecular structure of a plant photolyase protein that is surprisingly similar to two cryptochrome proteins that control the "master clock" in humans and other mammals. view more (2009-04-13)
Different Processes Govern Sight, Light Detection
A Johns Hopkins University biologist, in research with implications for people suffering from seasonal affective disorder and insomnia, has determined that the eye uses light to reset the biological clock through a mechanism separate from the ability to see. view more (2008-04-28)
Ytterbium gains ground in quest for next-generation atomic clocks
An experimental atomic clock based on ytterbium atoms is about four times more accurate than it was several years ago, giving it a precision comparable to that of the NIST-F1 cesium fountain clock, the nation's civilian time standard, scientists at the National Institute of Standards and Technology (NIST) report in Physical Review Letters. view more (2009-08-12)
Gene controlling circadian rhythms may be involved in onset of bipolar disorder
Disrupt the gene that regulates the biological clocks in mice and they become manic, exhibiting behaviors similar to humans with bipolar disorder, UT Southwestern Medical Center researchers have found. view more (2007-03-20)
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)
