Using a recently developed biomarker of aging known as an epigenetic clock, UCLA researchers working closely with a German team of investigators have found for the first time that obesity greatly accelerates aging of the liver. This finding could explain the early onset of many age-related diseases, including liver cancer, in people who are obese. (more…)

Some 10,000 years ago, people found they didn’t have to live as nomads, hunting and gathering all their food. In the Fertile Crescent, they started planting crops.
The Fertile Crescent extended from the Nile Valley and along the eastern Mediterranean Coast, through the Tigris and Euphrates valleys of Mesopotamia and down to the Persian Gulf. There, the foundation crops of the Western World were first domesticated. (more…)
AUSTIN, Texas — University of Texas at Austin researchers have demonstrated a new and more effective method for regrowing blood vessels in the heart and limbs — a research advancement that could have major implications for how we treat heart disease, the leading cause of death in the Western world.
The treatment method developed by Cockrell School of Engineering Assistant Professor Aaron Baker could allow doctors to bypass surgery and instead repair damaged blood vessels simply by injecting a lipid-incased substance into a patient. Once inside the body, the substance stimulates cell growth and spurs the growth of new blood vessels from pre-existing ones. (more…)

Pathological gamblers are risking more than their money, they are also three times more likely to commit suicide than non-betters. A new Montreal inter-university study has shown these gamblers are also plagued by personality disorders. These findings, published in a recent issue of the Psychology of Addictive Behaviors, may have implications for developing improved targeted suicide prevention programs.
“The World Health Organization estimates that suicide is one of the top ten causes of death in the Western world,” says study co-author, Richard Boyer a Université de Montréal professor and researcher at the Centre de recherche Fernand-Seguin at the Louis-H. Lafontaine Hospital. “In addition, pathological gamblers account for five percent of all suicides. These staggering statistics motivated us to study the difference between gamblers and non-gamblers.” (more…)
