Research conducted at Texas Health Presbyterian Hospital's Institute for Exercise and Environmental Medicine in Dallas suggests that it's never too late for women to reap the benefits of moderate aerobic exercise. In a 3-month study of 16 women age 60 and older, brisk walking for 30-50 minutes three or four times per week improved blood flow through to the brain as much as 15%.

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a microminiaturized device that can make complex viscosity measurements -- critical data for a wide variety of fields dealing with things that have to flow -- on sample sizes as small as a few nanoliters.

Scientists have long puzzled over the many hours we spend in light, dreamless slumber. But a new study from the University of California, Berkeley, suggests we're busy recharging our brain's learning capacity during this traditionally undervalued phase of sleep, which can take up half the night.

Scientists are reporting an in-depth analysis of how the caffeine in coffee, tea, and other foods seems to protect against conditions such as Alzheimer's disease and heart disease on the most fundamental levels.

Stress wreaks havoc on the mind and body. For example, psychological stress is associated with greater risk for depression, heart disease and infectious diseases. But, until now, it has not been clear exactly how stress influences disease and health.

After two decades of improvement, the percentage of Americans without major heart disease risk factors is dropping, according to a report in Circulation: Journal of the American Heart Association. “From a preventive health point of view, it’s important that individuals achieve as many of these goals as possible, and it’s disappointing that less than 10 ...

Since the 1930s scientists have proposed food restriction as a way to extend life in mice. Though feeding a reduced-calorie diet has indeed lengthened the life spans of mice, rats and many other species, new studies with dozens of different mouse strains indicate that food restriction does not work in all cases.

An overgrowth of bacteria in the gut has been definitively linked to Irritable Bowel Syndrome in the results of a new Cedars-Sinai study which used cultures from the small intestine. This is the first study to use this "gold standard" method of connecting bacteria to the cause of the disease that affects an estimated 30 million people in the United States.

There is no doubt that eating a balanced diet is essential for maintaining a healthy body weight as well as appropriate arousal and energy balance, but the details about how the nutrients we consume are detected and processed in the brain remain elusive. Now, a research study discovers...

A comprehensive assessment of the benefits of medical cannabis for cancer-related pain found that for most oncology patients, pain measures improved significantly, other cancer-related...

Obesity is the main culprit in the worldwide avalanche of Type 2 diabetes. But how excess weight drives insulin resistance, the condition that may lead to the disease, is only partly understood. Scientists at Joslin Diabetes Center now have uncovered a new way in which obesity wreaks its havoc, by altering the production of proteins that affect how other proteins are spliced together.

A group of scientists from across the world have come together in a just-published study that provides new insights into how fructose causes obesity and metabolic syndrome, more commonly known as diabetes. In this study which was performed in lab animals, researchers found that fructose can be metabolized by an enzyme that exists in two forms.
