Yeast gene makes old cells young again - New Scientist

That's great! Maybe the fountain of youth is just around the corner?

During sporulation, a gene called NDT80 was expressed. What's more, switching on NDT80 in ageing cells doubled their lifespan (Science, DOI: 10.1126/science.1204349). The closest relative of NDT80 in mammals is p53, a gene that regulates cell cycles. "We may have found a way to rejuvenate cells and erase ageing markers," says Amon.
