Keep your heart healthy and you may slow down the aging of your brain, according to a new study reported in Circulation: Journal of the American Heart Association. In the study, people whose hearts pumped less blood had brains that appeared older than the brains of those whose hearts pumped more blood.

When lean healthy young adults gained about 9 pounds, the functioning of their blood vessel lining became impaired -- but shedding the weight restored proper functioning, according to a Mayo Clinic research report. The finding is important because this vessel disorder, known as endothelial dysfunction, is a predictor of heart attacks and stroke, and the effects of modest weight gain on the disorder were not previously known.

People who sleep less than six hours a night may be three times more likely to develop a condition which leads to diabetes and heart disease, according to researchers at the University of Warwick.

Washington State University researchers have discovered the mechanism by which the brain switches from a wakeful to a sleeping state. The finding clears the way for a suite of discoveries, from sleeping aids to treatments for stroke and other brain injuries.

Simply getting older is not the cause of mild memory lapses often called senior moments, according to a new study by researchers at the Rush Alzheimer's Disease Center. The study, published in the September 15, 2010, online issue of Neurology, the medical journal of the American Academy of Neurology, found that even the very early mild changes in memory that are much more common in old age than dementia are caused by the same brain lesions associated with Alzheimer's disease and other dementias.

Researchers at Stanford University were able to use light to induce normal patterns of muscle contraction, in a study involving bio-engineered mice whose nerve-cell surfaces are coated with special light-sensitive proteins.

Insulin resistance, a condition in which insulin produced by the body becomes less effective in reducing blood glucose levels, appears to be associated with an increased risk of stroke in individuals without diabetes, according to a report in the October issue of Archives of Neurology, one of the JAMA/Archives journals.

No matter how you slice it, watermelon has a lot going for it -- sweet, low calorie, high fiber, nutrient rich -- and now, there's more. Evidence from a pilot study led by food scientists at The Florida State University suggests that watermelon can be an effective natural weapon against prehypertension, a precursor to cardiovascular disease.

The blood vessels of obese children have stiffness normally seen in much older adults with cardiovascular disease, Dr. Kevin Harris told the Canadian Cardiovascular Congress 2010, co-hosted by the Canadian Cardiovascular Society and the Heart and Stroke Foundation. The clock is ticking and the shape of the 13 year-old-heart is changing -- for the worse.

Dietary supplementation with sodium bicarbonate (baking soda) on the morning of a tennis match allows athletes to maintain their edge. A randomized, controlled trial reported in BioMed Central's open access Journal of the International Society of Sports Nutrition found that those players who received the supplement showed no decline in skilled tennis performance after a simulated match.

A new study has found that regular consumption of soda and other sugar-sweetened beverages is associated with a clear and consistently greater risk of metabolic syndrome and type 2 diabetes. According to the Harvard School of Public Health (HSPH) researchers, the study provides empirical evidence that intake of sugary beverages should be limited to reduce risk of these conditions.
