In this study, researchers developed highly precise tissue-specific clocks, capable of predicting age within about one year of an individual’s chronological age. They conducted their study of 237 macaques, who live in semi-natural conditions on Cayo Santiago (colloquially referred to as “Monkey Island”), a 38-acre island off Puerto Rico's east coast. The island is inhabited by over 1,500 free-ranging rhesus macaques and managed by the University of Puerto Rico and Caribbean Primate Research Center. By integrating multi-tissue DNA methylation collected in adulthood with detailed records of early life experiences, the team uncovered how adversity and aging interacted to shape biology at the molecular level.
