Working with mice, they found that the enzyme could reactivate chromosomes and effectively turn back the aging clock. Both of the mice they used were the same age, but the more youthful looking one had the enzyme treatment.
Scientists at the Dana-Farber Cancer Institute in Boston said they were able to reverse brain disease, restore sense of smell and even restore fertility by tweaking DNA in the mice.
Researchers admitted that they have a long way to go before they can turn back the aging clock in humans.
