If you tend to have trouble picking up the latest dance moves or learning to play a new piano piece, there might be an explanation. A new study published online on March 3rd in Current Biology, shows that people who are fast to learn a simple sequence of finger motions are also those whose brains show large changes in a particular chemical messenger following electrical stimulation.

An elderly person's risk of falling is too often overlooked when trying to prevent them from getting serious fractures, for instance of the hip or wrist, according to an article published in the British Medical Journal.

A new study from North Carolina State University shows that the vast majority of patients at high risk for heart disease or stroke do a poor job of taking statins as prescribed. That's especially unfortunate, because the same study shows that taking statins can significantly increase the quality and length of those patients' lives.

New research published online in the British Medical Journal adds to mounting evidence that calcium supplements increase the risk of cardiovascular events, particularly heart attacks, in older women.

The sight of unhealthy food during a period of sleep restriction activated reward centers in the brain that were less active when participants had adequate sleep, according to a new study using brain scans to better understand the link between sleep restriction and obesity.

In a study examining the factors that play a role in an older adult's transition to disability, intervening illnesses and injuries that led to hospitalization or activity restriction were associated with worsening functional ability, especially among those who were physically frail, according to a report in the November 3 issue of JAMA, a theme issue on aging.

An increased intake of 'good' potassium salts could contribute significantly to improving blood pressure at the population level, according to new research. The favorable effect brought about by potassium is even estimated to be comparable with the blood pressure reduction achievable by halving the intake of 'bad' sodium salts (mostly from table salt).

A meta-analysis of previously published studies finds no evidence that statins are associated with a reduced risk of death among individuals at risk for but with no history of cardiovascular disease, according to a report in the June 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Each year as many as 40,500 critically ill U.S. hospital patients die with an unknown medical condition that may have caused or contributed to their death, Johns Hopkins patient safety experts report in a recent study. In a discussion of their findings, described online in BMJ Quality & Safety, researchers say that although diagnostic errors in the intensive care unit (ICU) may claim as many lives each year as breast cancer, they remain an underappreciated cause of preventable patient harm.

The next time you feel your willpower slipping as you pass that mouth-watering dessert case, tighten your muscles. A new study in the Journal of Consumer Research says firming muscles can shore up self-control.

Patients who use anti-depressants are much more likely to suffer relapses of major depression than those who use no medication at all, concludes a McMaster researcher. In a paper that is likely to ignite new controversy in the hotly debated field of depression and medication, evolutionary psychologist Paul Andrews concludes that patients who have used anti-depressant medications can be nearly twice as susceptible to future episodes of major depression.

We've heard obesity can be "spread" between friends when we copy each other's eating habits, but a new study in mice suggests obesity could actually be infectious. That's right, infectious. As in, something you can catch.In the study, mice engineered to have a particular immune deficiency developed fatty liver disease and got fatter when fed a Western-style diet. But strikingly, when these immune-deficient mice were put in the same cage as healthy mice, the healthy mice started to come down with symptoms of liver disease, and also got fatter.
