Targeting the biology of aging offers a path to stronger resilience and longer health. John C. Newman, M.D., Ph.D., explains that aging arises from measurable cellular processes, often called hallmarks of aging, including changes involving mitochondria, stem cells, cellular senescence, inflammation, and protein quality control. Newman describes how basic science in model organisms reveals mechanisms that can be manipulated to extend healthy lifespan and guide therapies. Emerging approaches aim either to strengthen stress responses that make cells more resilient or to address downstream consequences. Many clinical studies across the country now test interventions that target aging, supported by national efforts to standardize methods and expand training. Newman also investigates ketone bodies as energy sources that influence inflammation, muscle preservation, and other processes relevant to frailty and recovery.
