By lowering the expression of a single gene, researchers have extended the average lifespan of a group of mice by about 20 percent -- the equivalent of raising the average human lifespan by 16 years, from 79 to 95. The research team targeted a gene called mTOR, which is involved in metabolism and energy balance, and may be connected with the increased lifespan associated with caloric restriction.
