Longer Genes May Drive Aging

Four independent studies converge on the groundbreaking conclusion that the activity of long genes may be the key driver behind aging. This insight, marking a significant shift from traditional gene-specific aging theories, suggests that conditions affecting long gene activity, like smoking or caloric restriction, can accelerate or slow down aging, respectively.
