Yeast Discovery could be the ‘Fountain of Youth’

Published in the journal Science on April 27, scientists aged yeast cells and rewired the aging process of yeast by reframing deterioration. They engineered a negative feedback loop which prevented deterioration and essentially created a clock-wise effect on the cell, prolonging and slowing aging.

Scientists found that cells usually take one of two paths — one is toward a healthy aging process, and the other is rapidly declining health. By discovering what determines which path a cell takes, researchers were able to rewire the path, called a gene oscillator — which acted like a toggle switch — and allowed the cells to live twice as long.
