Aging is a complex biological process that affects nearly every system in the body over time, leading to gradual physical, cognitive, and cellular changes. While aging is a natural part of life, researchers are actively uncovering the mechanisms that drive it—ranging from genetic factors and cellular senescence to inflammation and metabolic shifts. Scientific advances are also exploring how lifestyle, environment, and medical interventions can influence healthy aging and longevity. This page features the latest research and discoveries in the science of aging, including insights into age-related diseases, lifespan extension, and the biology of longevity.
