The body's cells respond to stress—toxins, mutations, starvation or other assaults—by pausing normal functions to focus on conserving energy, repairing damaged components and boosting defenses.

they converted male mouse stem cells into female cells and produced functional egg cells. Finally, they fertilized those eggs and implanted the embryos into female mice. About 1% of the embryos ...
