Engaging in regular physical activity is associated with less decline in cognitive function in older adults, according to two studies published Online First by Archives of Internal Medicine, one of the JAMA/Archives journals. The articles are being released on July 19 to coincide with the International Conference on Alzheimer's Disease in Paris and will be included in the July 25 print edition.

The United States continues to lag behind other nations when it comes to gains in life expectancy, and commonly cited causes for our poor performance -- obesity, smoking, traffic fatalities, and homicide -- are not to blame, according to a Commonwealth Fund-supported study published as a Health Affairs Web First.

Bone cells known as osteoblasts were recently shown to have a role in controlling the biochemical reactions that generate energy via secretion of the molecule osteocalcin. A team of researchers, led by Stavroula Kousteni, at Columbia University, New York, has now determined that the protein FoxO1 regulates this function of osteoblasts in mice.

The U.S. Department of Health and Human Services has added eight substances to its Report on Carcinogens, a science-based document that identifies chemicals and biological agents that may put people at increased risk for cancer.

A synthetic derivative of the curry spice turmeric, made by scientists at the Salk Institute for Biological Studies, dramatically improves the behavioral and molecular deficits seen in animal models of ischemic stroke and traumatic brain injury (TBI). Two new studies suggest that the novel compound may have clinical promise for these conditions, which currently lack good therapies.

Lack of physical exercise is often implicated in many disease processes. However, sedentary behavior, or too much sitting, as distinct from too little exercise, potentially could be a new risk factor for disease. The August issue of the American Journal of Preventive Medicine features a collection of articles that addresses many aspects of the problem of sedentary behavior...

Omega 3 fatty acids may be beneficial for more than just the heart. Researchers at the Indiana University School of Medicine have found at a molecular level a potential therapeutic benefit from these dietary supplements for treating alcohol abuse and psychiatric disorders.

New findings out of Wake Forest Baptist Medical Center reveal that a common test may be useful in predicting early death in individuals with diabetes. The study appears in the May issue of Diabetes Care.

A study led by Mount Sinai School of Medicine researchers of 192 pharmaceutical advertisements in biomedical journals found that only 18 percent were compliant...

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.

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.

As science rushes to develop safe weight loss drugs, a new research report approaches this problem from an entirely new angle: What if there were a pill that would make you want to exercise harder? It may sound strange, but a new research report appearing online in The FASEB Journal suggests that it might be possible.
