Biologists have created baker's yeast capable of living to 800 in yeast years, with no apparent side effects.
The achievement was reached through a combination of dietary and genetic changes. It could bring science closer to controlling the survival and health of the basic unit of all living systems -- the cell.
The yeast was put on a calorie-restricted diet, and had two genes, which promote aging in yeast and cancer in humans, deactivated. The result was a 10-fold life span extension.
