• Now, in yeast cells, researchers at Harvard Medical School and BIOMOL Research Laboratories have for the first time found a way to duplicate the benefits of restricted calories in yeast with a group of compounds found in red wine and vegetables. One compound extended yeast life span by up to 80 percent. The molecules are also active in human cells cultured in the laboratory. "The sirtuin stimulation provided by certain, but not all, polyphenols may be a far more important biological effect than their antioxidant action," said co-author Konrad Howitz, director of molecular biology at BIOMOL, a biochemical reagents company in Pennsylvania.
