Stunning new maps of myelin-making mouse brain cells advance understanding of nervous system disorders

Johns Hopkins Medicine
Peer-Reviewed Publication

Johns Hopkins scientists say they have used 3D imaging, special microscopes and artificial intelligence (AI) programs to construct new maps of mouse brains showing a precise location of more than 10 million cells called oligodendrocytes. These cells form myelin, a protective sleeve around nerve cell axons, which speeds transmission of electrical signals and support brain health.

Invisible harms: drug-related deaths spike after hurricanes and tropical storms

Columbia University's Mailman School of Public Health
Peer-Reviewed Publication

Tropical cyclones, including hurricanes and tropical storms, are linked to increased rates of drug-related deaths up to three months after the storm passes—particularly in higher-income, White communities and among younger populations. The study of more than 30 years of data by researchers at Columbia University Mailman School of Public Health points to one overlooked health impact of climate change, which is leading to more active and severe storms.

Adolescent cannabis use and risk of psychotic, bipolar, depressive, and anxiety disorders

JAMA Network
Peer-Reviewed Publication

About The Study: This cohort study found that adolescent cannabis use was associated with increased risk of incident psychiatric disorders, particularly psychotic and bipolar disorders. These results could inform the development of clinical and educational interventions for parents, adolescents, and clinicians, as well as protective policies to prevent or delay adolescent cannabis use in the context of expanding cannabis legalization.

Anxiety, depression, and care barriers in adults with intellectual and developmental disabilities

JAMA Network
Peer-Reviewed Publication

About The Study: In this cross-sectional study, U.S. adults with intellectual and developmental disabilities experienced substantially higher rates of mental health conditions, treatment use, and cost-related barriers compared with those without functional impairments. These findings highlight critical gaps for accessible, affordable, and disability-informed mental health services and policy reforms to address systemic inequities.
