IT WAS as if somebody had turned again time. As soon as-faltering paws gripped objects with renewed power. Hearts and livers regained their youthful vitality. Fuzzy reminiscences sharpened. And in response to Steve Horvath’s experiments, the organic age of his rats had been lower in half. “I was stunned,” he says.

Horvath, an anti-ageing researcher on the College of Los Angeles, California, and his colleagues noticed these startling results in 2020 after injecting outdated rats with blood extract from youthful rodents.
