The findings of a study published in Science today (9th October 2009) 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.

ANN ARBOR, Mich.---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.
STANFORD, Calif. — Researchers at the Stanford University School of Medicine have identified a key molecular player in guiding the formation of synapses — the all-important connections between nerve cells — in the brain. This discovery, based on experiments in cell culture and in mice, could advance scientists' understanding of how young children's brains develop as well as point to new approaches toward countering brain disorders in adults.
GAINESVILLE, Fla. --- Attention weekend warriors: the simple act of exercise and not fitness itself can convince you that you look better, a new University of Florida study finds.
People who don't achieve workout milestones such as losing fat, gaining strength or boosting cardiovascular fitness feel just as good about their bodies as their more athletic counterparts, said Heather Hausenblas, a UF exercise psychologist. Her study is published in the September issue of the Journal of Health Psychology.
An F1000 evaluation looks at a Canadian study on how giving caffeine to newborn rats has a long-lasting and detrimental effect on sleep and breathing in adulthood
Breathing problems are the leading causes of hospitalisation and death in premature babies. These babies are therefore often given caffeine because of its qualities as a respiratory stimulant. Until recently, the long-term effects of this treatment in humans have not been examined.
WASHINGTON – A 16-year-old might be quite capable of making an informed decision about whether to end a pregnancy – a decision likely to be made after due consideration and consultation with an adult – but this same adolescent may not possess the maturity to be held to adult levels of responsibility if she commits a violent crime, according to new research into adolescent psychological development.
Philadelphia, PA, 7 October 2009 - Ever since the Accreditation Council for Graduate Medical Educations (ACGME) and its Resident Review Committees instituted limitations on duty-hours for residents, in 2003, there has been an ongoing debate about the benefits and costs of the changes imposed on patient care and the education of residents.
The National Institute of Standards and Technology (NIST) has unveiled a method for calibrating entire waveforms—graphical shapes showing how electrical signals vary over time—rather than just parts of waveforms as is current practice. The new method improves accuracy in calibrations of oscilloscopes, common test instruments that measure voltage in communications and electronics devices, and potentially could boost performance and save money in other fields ranging from medical testing to structural analysis to remote sensing.
DURHAM, N.H -- A new study from the University of New Hampshire finds that U.S. children are routinely exposed to even more violence and abuse than has been previously recognized, with nearly half experiencing a physical assault in the study year.
"Children experience far more violence, abuse and crime than do adults," said David Finkelhor, director of the UNH Crimes against Children Research Center and the study director. "If life were this dangerous for ordinary grown-ups, we'd never tolerate it."
WEST BLOOMFIELD, Mich. – A Michigan hospital is embarking on a research study for advanced Parkinson's disease using a state-of-the-art treatment called gene transfer.
The clinical trial will test whether gene transfer therapy is able to restore better mobility in Parkinson's patients who have lost responsiveness to drug therapy.
PHILADELPHIA – While little is known about the causes of glioma, researchers at the National Cancer Institute have found that this rare but often deadly form of brain cancer may be linked to early life physical activity and height.
WEST LAFAYETTE, Ind. - Just like Lucy pulling the football away from Charlie Brown, kicking a football through goal posts can be an elusive task, according to Purdue University research.
"People trying to kick field goals will see a much smaller goal after unsuccessful attempts," said Jessica K. Witt, an assistant professor of psychological sciences who studies perception in athletes. "But those who kicked better judged the goal posts to be farther apart and the crossbar lower to the ground."
DALLAS – Oct. 6, 2009 – The action of a small protein that is a major villain in Alzheimer's disease can be counterbalanced with another brain protein, researchers at UT Southwestern Medical Center have found in an animal study.
The findings, available online in the journal Proceedings of the National Academy of Sciences, suggest a promising new tactic against the devastating illness, the researchers said.
New research from the University of Southampton has demonstrated that it is possible for communication from person to person through the power of thought alone.
Brain-Computer Interfacing (BCI) can be used for capturing brain signals and translating them into commands that allow humans to control (just by thinking) devices such as computers, robots, rehabilitation technology and virtual reality environments.
