AI Summary

Scientists used a drug to activate a protein that regulates energy levels, and in a preclinical study the treatment increased the lifespans of several animal species by more than 25% in some cases. The research, published in *Aging Cell*, provides strong evidence that this “energy saver” mode can significantly extend longevity across multiple species. The study demonstrates that targeting the protein’s activity may be a promising strategy for age‑related interventions.
