New fruit fly protein illuminates circadian response to light
Researchers at the University of Pennsylvania School of Medicine have identified a new protein required for the circadian response to light in fruit flies. view more (2006-06-30)
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)
WUSTL research finds individual cells isolated from the biological clock can keep daily time, but are unreliable
Alexis Webb enters a small room at Washington University in St. Louis with walls, floor and ceiling painted dark green, shuts the door, turns off the lights and bends over a microscope in a black box draped with black cloth. Through the microscope, she can see a single nerve cell on a glass cover slip glowing dimly. view more (2009-09-10)
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)
Old gastrointestinal drug slows aging, McGill researchers say
Recent animal studies have shown that clioquinol - an 80-year old drug once used to treat diarrhea and other gastrointestinal disorders - can reverse the progression of Alzheimer's, Parkinson's and Huntington's diseases. view more (2009-01-07)
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)
OHSU primate center research suggests multiple 'body clocks'
Research conducted at Oregon Health & Science University suggests that contrary to popular belief, the body has more than one "body clock." view more (2006-05-23)
FLYING THROUGH TIME
UK scientists demonstrate Einstein's theories of relativity and 'travel' through time view more (1999-12-22)
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)
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)
Racing against the clock to distribute H1N1 flu vaccine
Drug companies are sprinting ahead in a race against the clock to deliver millions of doses of vaccine for the H1N1 influenza virus before cooler weather ushers in the 2009-2010 flu season. view more (2009-10-01)
Mood Lighting: Penn Researchers Determine Role of Serotonin in Modulating Circadian Rhythm
Researchers at the University of Pennsylvania School of Medicine have determined how serotonin decreases the body's sensitivity to light and that exposure to constant darkness leads to a decrease in serotonin levels in the brain of fruit flies. view more (2005-07-11)
Pain and stiffness intensity ebb and flow according to body clock in osteoarthritic patients
Levels of pain intensity and arthritic stiffness closely follow the rhythms of the body clock, reveals research in the Annals of the Rheumatic Diseases. view more (2002-11-12)
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)
Atomic clock signals may be best shared by fiber-optics
Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS). But today's best atomic clocks are so accurate—neither gaining nor losing one second in as long as 400 million years—that more stable methods are needed. view more (2007-03-05)
The food-energy cellular connection revealed
Our body's activity levels fall and rise to the beat of our internal drums-the 24-hour cycles that govern fundamental physiological functions, from sleeping and feeding patterns to the energy available to our cells. view more (2009-10-16)
NIST atomic fountain clock gets much better with time
The world's best clock, NIST-F1, has been improved over the past few years and now measures time and frequency more than twice as accurately as it did in 1999 when first used as a national standard, physicists at the National Institute of Standards and Technology (NIST) report. view more (2005-09-26)
Scientists unravel the molecular basis of monarch butterfly migration
Since its discovery, the annual migration of eastern North American monarch butterfly has captivated the human imagination and spirit. That millions of butterflies annually fly up to 2000 miles to reach a cluster of pine groves in central Mexico comprising just 70 square miles is for many an awesome and mysterious occurrence. view more (2008-01-09)
'Suction climbing' and Vertical Cycling at TU Delft
Invitation to the final of the design contest at Mechanical Engineering 'Suction climbing' and Vertical Cycling at TU Delft Students that climb along walls and ceilings like geckos, or that ride a bike up a cable. This can be seen at TU Delft on 7 June 2002, during the annual design contest at the Faculty of Mechanical Engineering. "At this... view more... (2002-06-04)
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)
