A new study led by a University of California, Berkeley, researcher could give women a little extra motivation to visit their dentist more...

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.

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.

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.

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.

Researchers at McMaster University have developed a cocktail of ingredients that forestalls major aspects of the aging process. The findings are published in the...

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.

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.

Harvard University researchers have uncovered a mechanism through which caloric restriction and exercise delay some of the debilitating effects of aging by rejuvenating connections between nerves and the muscles that they control.

People whose blood shows signs of inflammation are more likely to later develop Alzheimer's disease than people with no signs of inflammation, according to a study published in the May 29, 2007, issue of Neurology®, the scientific journal of the American Academy of Neurology.

Calcium supplements, commonly taken by older people for osteoporosis, are associated with an increased risk of a heart attack, finds a study published online in the British Medical Journal. The results suggest that a reassessment of the role of calcium supplements in osteoporosis management is needed.

Melinda Sothern, PhD, CEP, Professor of Public Health and Director of Health Promotion at LSU Health Sciences Center New Orleans, will present evidence that supports relationships seen in adolescents between insulin sensitivity and fatty liver, belly fat, and total body fat and identifies additional potential early markers of insulin resistance and metabolic syndrome in healthy 7-9 year-old children, including fat in muscle cells, blood pressure, physical activity, and birth weight.
