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.
