How Yeast Hit the Reset Button on Life: Cellular Rejuvenation in a Microchannel
The yeast that bakes our bread knows how to cheat time. Its sex cells are born with a full supply of divisions, even if the parent cell has already grown old. But exactly how a cell clears out accumulated damage long remained a mystery: measuring the age of hundreds of gametes by hand was far too labor-intensive.
