The National Institutes of Health (NIH) is offering a funding opportunity for access to biospecimens from the Adolescent Brain Cognitive Development (ABCD) Study, a significant longitudinal research initiative aimed at understanding brain development and child health. Investigators can apply for biological samples, including saliva, blood, urine, and teeth, to support studies related to adolescent health; however, no funding is provided through this opportunity, and applicants must secure their own financing. This initiative is crucial for advancing knowledge in child health and development while promoting scientific collaboration, with applications due by May 5, 2026. Interested parties can find more information and application guidelines on the NIH grants website or contact NIH Grants Information at grantsinfo@nih.gov for further inquiries.
