The Department of Health and Human Services announces a funding opportunity for access to biospecimens from the Adolescent Brain Cognitive Development (ABCD) Study, managed by NIH's Brain Development Cohorts Biorepository. This longitudinal research initiative will collect data from over 11,000 children to explore the interplay between childhood experiences and brain development. Investigators can apply for biological samples including oral fluids, blood, and teeth for studies related to adolescent health. With no funding provided through this opportunity, applicants must secure their own research financing and follow specific application guidelines, adhering to various requirements, including submission deadlines. Key dates for the application process span from September 5, 2023, with the NIH urging early submissions to allow correction of any errors. The initiative aims to advance understanding of child health and development while promoting open scientific collaboration. Successful applications must demonstrate the significance of the proposed research while ensuring that access to biospecimens aligns with ethical considerations surrounding participant consent and potential resource depletion.
