Researchers at Boston's Dana-Farber Cancer Institute reverse the aging process in mice using a gene therapy technique.

Researchers at Boston's Dana-Farber Cancer Institute managed to reverse brain disease and restore fertility and the sense of smell in prematurely aged mice, using a gene therapy technique.
The aging process shortens coatings on the ends of chromosomes, called telomeres, causing cells to stop dividing, stem cells to hibernate, brain cells to die and organs to atrophy. By restoring the telomeres in the mice, scientists were able to halt these processes, according to a study published in the journal Nature.
