Physicists make atomic clock breakthrough
Andrei Derevianko, Kyle Beloy, and Ulyana Safronova sat down six months ago and began work on a calculation that will help the world keep better time. In competition with scientists at the University of New South Wales, the University team led by associate professor Derevianko conducted research that increased the accuracy of atomic clocks, and... view more...

A Biological Basis for the 8-Hour Workday?
The circadian clock coordinates physiological and behavioral processes on a 24-hour rhythm, allowing animals to anticipate changes in their environment and prepare accordingly. Scientists already know that some genes are controlled by the clock and are turned on only one time during each 24-hour cycle. view more (2009-04-24)
Chemotherapy for breast cancer is associated with disruption of sleep-wake rhythm in women
A study in the Sept.1 issue of the journal Sleep shows that the sleep-wake activity rhythms of breast cancer patients are impaired during the administration of chemotherapy. view more (2009-09-01)
Emergency angioplasty patients do best at hospitals where it's the 'default' treatment
Across America, hospitals large and small have been racing to offer angioplasty and other minimally invasive treatments to open blocked heart arteries. view more (2006-01-17)
New molecular clock from LLNL and CDC indicates smallpox evolved earlier than believed
Smallpox is older than thought, according to results of a new technique reported in the Sept. 24 issue of the Proceedings of the National Academy of Sciences by researchers from Lawrence Livermore National Laboratory and the Centers for Disease Control (CDC). view more (2007-09-26)
Invisible waves shape continental slope
A class of powerful, invisible waves hidden beneath the surface of the ocean can shape the underwater edges of continents and contribute to ocean mixing and climate, researchers from The University of Texas at Austin have found. view more (2008-07-01)
Tides, Earth's rotation among sources of giant underwater waves
Scientists at the University of Rhode Island are gaining new insight into the mechanisms that generate huge, steep underwater waves that occur between layers of warm and cold water in coastal regions of the world's oceans. view more (2010-02-25)

An interdisciplinary team of researchers at Vanderbilt University has analyzed the simplest known biological clock and figured out what makes it tick. view more (2007-03-27)
A Therapy for Baby Boomers to Sleep On
If you're over 55 and have spent more than a few sleepless nights, you're not alone -- insomnia affects about half of all people over 55 ― but you may also be at increased risk for physical and mental ailments. view more (2008-08-18)
Computers explain why pears may become brown during commercial storage
Internal browning of pears stored under low oxygen conditions is related to restricted gas exchange inside the fruit, according to a study published March 7th in the open-access journal PLoS Computational Biology. view more (2008-03-10)
New medication brings hope of jet lag cure
A team of researchers from Monash University, The Brigham and Women's Hospital (Boston), Harvard Medical School and Vanda Pharmaceuticals has found a new drug with the potential to alleviate jet lag and sleep disorders caused by shift work. view more (2008-12-02)
Invention gives improved gene technology analysis
A patent for a system that gives more reliable results in gene technology-based diagnostic tests has been granted to researchers at the Norwegian Institute of Public Health (NIPH). view more (2008-04-25)
Fire and water reveal new archaeological dating method
Scientists at The University of Manchester have developed a new way of dating archaeological objects - using fire and water to unlock their 'internal clocks'. view more (2009-05-20)
Knobbly kneed ID
Forget LED thumb-pad identification devices, complex retinal laser scanning, or even computerized iris recognition, the way forward for biometric validation is a quick X-ray snapshot of a person's knees, according to a report published in the International Journal of Biometrics. view more (2009-03-26)
Blood's clotting cells harbor 'ticking time bombs,' finding may help extend blood supply
Fragments of cells in the blood known as platelets—which form blood clots and assist in wound healing—have internal "clocks" that act like ticking time bombs, predetermining their death from the moment they are born, according to a new study in the March 23 issue of the journal Cell, published by Cell Press. view more (2007-03-23)
Scientist refines cosmic clock to determine age of Milky Way
The University of Chicago's Nicolas Dauphas has developed a new way to calculate the age of the Milky Way that is free of the unvalidated assumptions that have plagued previous methods. view more (2005-06-30)
Inner Workings of Molecular Thermostat Point to Pathways to Fight Diabetes, Obesity, According to Penn Study
Best known as the oxygen-carrying component of hemoglobin, the protein that makes blood red, heme also plays a role in chemical detoxification and energy metabolism within the cell. Heme levels are tightly maintained, and with good reason: Too little heme prevents cell growth and division; excessive amounts of heme are toxic. view more (2009-09-14)
Diagnostic ultrasound could provide automated method of fingerprint identification
Diagnostic 3D ultrasound of fingers could be used for biometric identification based on matching paired images using internal fingerprint structures that would be difficult to fake, offering the possibility of a unique automated fingerprint identification system. view more (2007-05-07)
Computer model improves ultrasound image
Doctors use diagnostic sonography or ultrasound to visualise organs and other internal structures of the human body. view more (2008-11-05)
Bacteria pack their own demise
Numerous pathogens contain an 'internal time bomb', a deadly mechanism that can be used against them. After years of work, VIB researchers at the Vrije Universiteit Brussel (VUB) were able to determine the structure and operating mechanism of the proteins involved. view more (2009-07-31)
