A Norwegian survey carried out between 1974 and 2003 showed that there was a graded independent increase in the risk of AF with increasing levels of physical activity in a population-based study among men with ostensibly no other heart disease. In women the data were inconclusive.

New research from the University of Montreal shows that inattention, rather than hyperactivity, is the most important indicator when it comes to finishing a high school education. "Children with attention problems need preventative intervention early in their development," explained lead author Dr. Jean-Baptiste Pingault, who is also affiliated with Sainte-Justine Mother and Child University Hospital. The researchers came to their conclusion after looking at data collected from the parents and teachers of 2000 children over a period of almost twenty years.

The premise behind a symposium occurring today at the National Meeting & Exposition of the American Chemical Society is the lack of charm, charisma, people skills and communication skills among the 20 million science and engineering people in the US alone.

Called "Empowering Tomorrow's Science Super Heroes", it opens a discussion on how to give scientists a touch of the panache of the stock comic book and Hollywood characters who worked for the public good.

DURHAM, N.C.—A large-scale trial finds that apixaban, a new anticoagulant drug, is superior to the standard drug warfarin for preventing stroke and systemic embolism in patients with atrial fibrillation. Moreover, apixaban results in substantially less bleeding and also results in lower mortality.

The results were presented by Duke University Medical Center researchers at the European Society of Cardiology in Paris, France, today, and published simultaneously online in the New England Journal of Medicine.

The rising prevalence of obesity around the globe places an increasing burden on the health of populations, on health care systems and on overall economies.

Using a simulation model to project the probable health and economic consequences from rising obesity rates in the United States and the United Kingdom, researchers at Columbia University's Mailman School of Public Health and Oxford University forecast 65 million more obese adults in the U. S. and 11 million more in the U.K. by 2030, leading to millions of additional cases of diabetes, heart disease, stroke, and cancer.

Acorn woodpeckers are cooperative breeders, meaning adult birds often join breeding groups and help raise young that are not their own.

Scientists have long thought that communal breeding may have evolved to help birds deal with food shortages and other difficult times, but a study by researchers from Cornell and Gonzaga shows that for acorn woodpeckers, the opposite seems to be true: Help contributed by other family members is beneficial only when the acorn crop is large.

(SACRAMENTO, Calif.) — People with lower socioeconomic status are much more likely to develop heart disease than those who are wealthier or better educated, according to a recent UC Davis study. Published online in BMC Cardiovascular Disorders, the outcomes also show that this risk persists even with long-term progress in addressing traditional risk factors such as smoking, high blood pressure and elevated cholesterol.

It has long been known that hereditary factors play a role in coronary heart disease. However, it has been unclear whether the increased risk is transferred through the genes or through an unhealthy lifestyle in the family. A new study from the Center for Primary Health Care Research in Sweden, published in the American Heart Journal, shows that genes appear to be most important.

"It's not that the salmon are biting less, there are less of them," explained Eva García Vázquez, lead author and Functional Biology researcher at the University of Oviedo (Spain).

The study, published in Transactions of the American Fisheries Society, shows a "very marked" decline in Atlantic salmon (Salmo salar) populations in the Narcea, Sella and Cares rivers (Asturias, northern Spain), especially during the last decade, almost simultaneously with the reduction in the amount caught by recreational fishermen.

Providing access to an outpatient clinic isn't enough to keep some trauma patients who have been discharged from the hospital from returning to the emergency department (ED) for follow-up care, even for such minor needs as pain medication refills and dressing changes, according to new Johns Hopkins research.

Believe it or not, one thing that predicts how well a CEO's company performs is the width of his face, according to Elaine M. Wong at the University of Wisconsin-Milwaukee and her colleagues.

MADISON - Globally, irrigation increases agricultural productivity by an amount roughly equivalent to the entire agricultural output of the U.S., according to a new University of Wisconsin-Madison study.

That adds up to a sizeable impact on carbon uptake from the atmosphere. It also means that water shortages - already forecasted to be a big problem as the world warms - could contribute to yet more warming through a positive feedback loop.

Temporary staff members working in a hospital's fast-paced emergency department are twice as likely as permanent employees to be involved in medication errors that harm patients, new Johns Hopkins research suggests.

San Diego, CA, August 30, 2011 – The benefits of physical activity accumulate across a lifetime, according to a new study published in the October issue of the American Journal of Preventive Medicine. Researchers in England and Australia examined the associations of leisure time physical activity across adulthood with physical performance and strength in midlife in a group of British men and women followed since birth in March 1946.

WASHINGTON, D.C. – At its public meeting on August 29 in Washington, the Presidential Commission for the Study of Bioethical Issues will publicly discuss several key findings as it refines the conclusions of its historical investigation into the U.S. Public Health Service (U.S. PHS) studies done in Guatemala in the 1940s. The U.S. PHS research involved intentionally exposing and infecting vulnerable populations to sexually transmitted diseases. The Commission's historical investigation is due to President Obama in September.
