NIST method improves reliability of GPS clocks
Widely used by the military, first responders, surveyors and even consumers, GPS is a navigation and positioning system consisting of ground-based monitors and a constellation of satellites that rely on atomic clocks. view more (2005-10-10)
A resetting signal keeps circadian rhythm on track in Drosophila fruit flies
A Brandeis University study published this week in Nature shows for the first time that a molecular signal maintains coherence among brain clock cells that regulate daily activity of Drosophila melanogaster (fruit flies). view more (2005-11-10)
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)
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)
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)
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)
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)
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)
New method to directly probe the quantum collisions of individual atoms
The first demonstration of a fundamentally new method for measuring a particular quantum property of individual atoms will be described in a research paper to be published in the 19 April 2007 edition of the journal Nature. view more (2007-04-19)
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)
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)
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)
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)
Research Paper Illuminates How Light Pushes Atoms
A research paper published in the 18 August edition of the journal Physical Review Letters reveals a new effect in the fundamental way that laser light interacts with atoms. view more (2006-08-21)
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)
REDUCED LONGEVITY OF ATOMIC-BOMB SURVIVORS (p 303)
A study in this week's issue of THE LANCET does not support claims that atomic-bomb survivors exposed to certain doses of radiation live longer than comparable unexposed individuals. There have been conflicting claims regarding the biological and health consequences of exposure to low doses of radiation, with reports that some atomic-bomb... view more... (2000-07-19)
Nanostructures can pose big measurement problems
Materials scientists will tell you that to best understand, characterize and eventually utilize the properties of a specific material, you have to be able to define how the atoms within it are arranged. view more (2007-04-30)
