Scientists have long known that cutting calories can extend lifespan, at least in lab animals. Now, new research suggests that rapamycin—a drug originally used to prevent organ transplant rejection—might offer similar longevity benefits without the need for drastic diet changes. While the findings are still limited to animal studies, it’s a promising hint that we could one day have a pill that mimics the life-extending effects of calorie restriction.

Editor’s Note: If you’ve ever winced at the idea of slashing your food intake to live longer, this could be good news. Rapamycin might offer a workaround, though it’s still early days—human trials will be key. For now, it’s a fascinating step toward understanding how we might slow aging without extreme lifestyle changes.
