Scientists may one day slow down aging with a simple injection of youthful stem cells. They’ve just proven this can be done in mice, according to a study published Tuesday in Nature Communications. The mice, which had been engineered to mimic a human disease called progeria, would normally have grown old when they were quite young.
Senh: That's getting scary. By the time this becomes useful, we'll hopefully have colonized the moon and Mars for the increasing population.
