Scientists take a step closer to an elixir of youth
"Researchers believe boosting the amount of a naturally forming enzyme in the body could prevent cells dying and so lead to extended, healthier, lifespans..
The protein telomerase helps maintain the protective caps at the ends of chromosomes which act like the ends of shoelaces and stop them unravelling.
As we age, and our cells divide, these caps become frayed and shorter and eventually are so damaged that the cell dies. Scientists believe boosting our natural levels of telomerase could rejuvenate them."
