Late weekend sleep among teens may lead to poor academic performance
Teenagers who stay up late on school nights and make up for it by sleeping late on weekends are more likely to perform poorly in the classroom. view more (2007-06-13)
Gene that makes people 'early to bed and early to rise' demystified
The recent discovery that a mutant "clock" gene made some people "early to bed and early to rise," a condition known as familial advanced sleep phase syndrome (FASPS), offered one of the first glimpses into the genetic basis of sleep in humans. view more (2007-01-12)
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)
U-M physicists create first atomic-scale map of quantum dots
University of Michigan physicists have created the first atomic-scale maps of quantum dots, a major step toward the goal of producing "designer dots" that can be tailored for specific applications. view more (2009-09-30)
Plants in the fourth dimension
As anyone who has suffered from jetlag knows, we have internal clocks that tell us when to sleep and wake, and we can be miserable when these are disrupted. view more (2008-07-01)
New paper describes connections between Circadian and metabolic systems
A paper by University of Notre Dame biologist Giles Duffield and a team of researchers offers new insights into a gene that plays a key role in modulating the body's Circadian system and may also simultaneously modulate its metabolic system. view more (2009-11-13)
UNC study supports role of circadian clock in response to chemotherapy
For years, research has hinted that the time of day that cancer patients receive chemotherapy can impact their chances of survival. But the lack of a clear scientific explanation for this finding has kept clinicians from considering timing as a factor in treatment. view more (2009-01-13)
Keeping the body in sync — The stability of cellular clocks
A study in Switzerland uses the tools of physics to show how our circadian clocks manage to keep accurate time in the noisy cellular environment. view more (2007-03-13)
Discovery of new gene associated with diabetes risk suggests link with body clock
A connection between the body clock and abnormalities in metabolism and diabetes has been suggested in new research by an international team involving the University of Oxford, the Wellcome Trust Sanger Institute and the MRC Epidemiology Unit in Cambridge. view more (2008-12-08)
New imaging technique reveals the atomic structure of nanocrystals
A new imaging technique developed by researchers at the University of Illinois overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom (less than one hundred-millionth of a centimeter). view more (2009-02-19)
Rutgers researchers 'rewrite the book' in quantum statistical physics
An important part of the decades-old assumption thought to be essential for quantum statistical physics is being challenged by researchers at Rutgers, The State University of New Jersey, and colleagues in Germany and Italy. view more (2006-02-10)
Stopping atoms
With atoms and molecules in a gas moving at thousands of kilometres per hour, physicists have long sought a way to slow them down to a few kilometres per hour to trap them. view more (2007-10-03)
Dramatic developments at Kilauea Volcano: Scientists work to keep public safe and informed
Explosive eruptions and noxious gas emissions at Kilauea Volcano in Hawaii this week have prompted scientists to work around the clock to understand what will happen next and how to keep the public out of harm's way. view more (2008-03-28)
THE MYSTERY OF HUYGENS CLOCKS EXPLAINED - Proceedings of the Royal Society Series A Vol. 458, No. 2019 Cover Date 8 March 2002
Christiaan Huygens` observations in 1665 of anti-phase synchronisation in two pendulum clocks were the subject of some of the earliest deliberations of The Royal Society but have remained a scientific puzzle. Huygens` acute observations are often quoted but have never been adequately explained - until today. The forthcoming issue of Proceedings A,... view more... (2002-02-13)
Central and peripheral signals set the circadian liver clock
Anyone who has experienced jet lag will understand the importance of a smooth-running circadian clock. Crossing time zones decouples our biological rhythms from the natural cycle of light and dark we're used to. view more (2007-01-30)
Joop Hermens awarded SETAC Europe Environmental Education Award
Dr. Joop Hermens was awarded the 2004 Society of Environmental Toxicology and Chemistry (SETAC) Europe Environmental Education Award, sponsored by Dr. U. Noack Laboratorien. Though the award was intended to honor Hermens, he saw it as an acknowledgement of the effort from the environmental toxicology and chemistry research group at the Institute... view more...

Tiny spectrometer offers precision laser calibration
A tiny device for calibrating or stabilizing precision lasers has been designed and demonstrated at the National Institute of Standards and Technology (NIST). view more (2007-05-14)
Structure of enzyme against chemical warfare agents determined
The enzyme DFPase from the squid Loligo vulgaris, is able to rapidly and efficiently detoxify chemical warfare agents such as Sarin, which was used in the Tokyo subway attacks in 1995. view more (2009-01-29)

New Speed Record for Magnetic Memories
Fast memory chips such as DRAMs and SRAMs (Dynamic and Static Random Access Memory) commonly used today have one decisive disadvantage: in case of power interruption, they lose their stored information. view more (2008-08-19)
