The study found that caffeine influences energy pathways linked to AMPK which is a key energy sensor that helps the cells to respond to stress.(Image: Canva) For millions of people, a morning cup of coffee is almost a ritual, something that feels as much like a necessity as it does a pleasure. But a growing body of research now suggests that caffeine, the key stimulant in coffee, may be doing something far more significant inside our bodies than simply keeping us alert. A new study from the Cellular Ageing and Senescence Laboratory at Queen Mary University of London , published in the journal Microbial Cell, has found that caffeine changes how cells move through their natural life cycle and how they respond to damage. It does this by activating a deeply rooted energy pathway in the body, one that scientists are increasingly linking to how long living organisms survive and age.…
