Now, Israeli and American scientists have shed light on how one of these systems works, offering clues for extending healthy, active years later in life.

The study focused on a protein known for its role in longevity and disease prevention. Scientists found that it does more than simply protect against ageing: it carefully regulates a molecule called hydrogen sulfide, which supports wound healing, cardiovascular health, and brain function. While hydrogen sulfide levels naturally drop wi...
