Scientists have unraveled key mechanisms behind the mysteries of aging. They isolated two distinct paths that cells travel during aging and engineered a new way to genetically program these processes to extend lifespan. Cells embark upon either a nucleolar or mitochondrial path early in life, and follow this ”aging route” throughout their entire lifespan through decline and death. At the heart of the controls the researchers found a master circuit that guides these aging processes.
