A new study done with mice has discovered that supplements of lipoic acid can inhibit formation of arterial lesions, lower triglycerides, and reduce blood vessel inflammation and weight gain – all key issues for addressing cardiovascular disease.

Biologists have created baker’s yeast capable of living to 800 in yeast years without apparent side effects. The basic but important discovery, achieved through a combination of dietary and genetic changes, brings science closer to controlling the survival and health of the unit of all living systems: the cell.

One of the nation’s pre-eminent genetic researchers, Eric Hoffman, PhD, of Children’s Research Institute at Children’s National Medical Center, predicts that in relatively short order, medicine
