Aging

Researchers from the Perelman School of Medicine at the University of Pennsylvania have identified an abnormal amount a protein called Prostaglandin D2 in the bald scalp of men with male pattern baldness, a discovery that may lead directly to new treatments for the most common cause of hair loss in men.

Popcorn's reputation as a snack food that's actually good for health popped up a few notches as scientists recently reported that it contains more of the healthful antioxidant substances called "polyphenols" than fruits and vegetables. They spoke at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), in San Diego on March 25.

New research finds that a person's memory declines at a faster rate in the two- and-a-half years before death than at any other time after memory problems first begin. A second study shows that keeping mentally fit through board games or reading may be the best way to preserve memory during late life. Both studies are published in the April 4, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Researchers have identified key genes that switch off with aging, highlighting them as potential targets for anti-aging therapies. Researchers at King's College London, in collaboration with the Wellcome Trust Sanger Institute, have identified a group of 'aging' genes that are switched on and off by natural mechanisms called epigenetic factors, influencing the rate of healthy aging and potential longevity.

Researchers at NYU School of Medicine have, for the first time, identified a single gene that simultaneously controls inflammation, accelerated aging and cancer. "This was certainly an unexpected finding," said principal investigator Robert J. Schneider, PhD, the Albert Sabin Professor of Molecular Pathogenesis, associate director for translational research and co-director of the Breast Cancer Program at NYU Langone Medical Center.

A major new study claims the pricey supplement TA-65 may turn back the clock, all the way down to our DNA—but many scientists are brushing it off as snake oil. Thea Singer investigates. In an era of seemingly magical technology, the notion that scientists could develop a pill that might slow the aging process doesn’t seem that far-fetched.

For years the Mediterranean diet has been associated with a lesser chance of illness and increased well-being. A new study has now linked it to mental and physical health too. The Mediterranean diet, which is characterised by the consumption of fruit, vegetables, pulses (beans, peas, chickpeas and lentils etc.) , fish, olive oil and nuts, has been proven to be beneficial to the health in terms of a lesser chance of chronic illness and a lower mortality rate.

Despite modest gains in lifespan over the past century, the United States still trails many of the world's countries when it comes to life expectancy, and its poorest citizens live approximately five years less than more affluent persons, according to a new study from Rice University and the University Colorado at Boulder.

In a recent study, investigators at Boston University Schools of Medicine (BUSM) and Public Health (BUSPH) identified a gene linking age-related cataracts and Alzheimer's disease. The findings, published online in PLoS ONE, contribute to the growing body of evidence showing that these two diseases, both associated with increasing age, may share common etiologic factors.

A study carried out by Dr. Louis Bherer, PhD (Psychology), Laboratory Director and Researcher at the Institut universitaire de gériatrie de Montréal (IUGM), an institution affiliated with Université de Montréal, has shown that all seniors, even those considered frail, can enjoy the benefits of exercise in terms of their physical and cognitive faculties and quality of life and that these benefits appear after only three months.

The combination of two neuroprotective therapies, voluntary physical exercise, and the daily intake of melatonin has been shown to have a synergistic effect against brain deterioration in rodents with three different mutations of Alzheimer's disease.

A new study has outlined for the first time a biological mechanism by which zinc deficiency can develop with age, leading to a decline of the immune system and increased inflammation associated with many health problems, including cancer, heart disease, autoimmune disease and diabetes.
