Move over, anti-aging cream. Researchers have found a new biological clock in human DNA that determines the rate at which bodily tissues agerevealing some surprising things about which parts of our bodies feel the brunt of aging soonest, and how such aging may eventually be reversed.
Geneticist Steve Hovarth explained in the Daily Mail,
"To fight ageing, we first need an objective way of measuring it My goal in inventing this clock is to help scientists improve their understanding of what speeds up and slows down the human ageing process."
Hovarth's team looked at 8,000 tissue samples that had been gathered for previous studies on DNA methylationthe process by which methyl groups are added to or taken away from DNA to change its expression. This process, a type of epigenetic modification, occurs early on in human development as cells diff
