Researchers artificially age rodents by suppressing a gene that helps repair telomeres, then rejuvenate them by turning back on the genetic switch. But the work is far from any use on humans. Have scientists finally discovered the genetic fountain of youth? Hardly. But by creating a genetic switch that allows them to artificially age — and rejuvenate — lab mice, scientists have shown that it is possible to reverse some effects of aging in mammals.
