New Research Reveals That Your Morning Coffee Activates an Ancient Longevity Switch

Researchers at Queen Mary University of London found caffeine affects fission yeast by activating AMPK, a conserved energy-sensing pathway.

Rather than directly hitting major growth-control routes like TORC1, caffeine changed stress responses, DNA-damage handling, and cell-division timing.

The study also linked caffeine to lifespan-related cell viability, suggesting a broader role in cellular aging.

The findings offer new clues about how a common dietary compound may influence longevity biology and overlap with drugs like metformin.
