Key molecule of aging discovered

Every cell and every organism ages sooner or later. But why is this so? Scientists have now discovered for the first time a protein that represents a central switching point in the aging process. It controls the life span of an individual — from the fly to the...

Cells stop dividing when this gene kicks into high gear

Scientists seeking to unlock secrets of cellular aging have identified a gene that triggers senescence, a phenomenon in which cells stop dividing. The gene, called CD36, is unusually active in older, senescent cells. Heightening CD36 activity also caused young,...
