Regular cannabis use during adolescence can alter brain development in ways that may have lasting consequences for cognition and mental health. Researchers continue to find links between teenage marijuana use and changes in brain structure and function, raising concerns as the drug becomes more accessible and socially normalized. The findings add urgency to public health conversations about age restrictions and youth education.
Read article →Teenagers who use cannabis show measurably slower development in thinking and memory skills, according to the largest study of its kind conducted in the United States. Researchers at UC San Diego analyzed data from more than 11,000 participants over time, finding consistent cognitive gaps between users and non-users. The findings add significant weight to growing concerns about cannabis's impact on the still-developing adolescent brain.
Read article →Scientists at USC's Keck School of Medicine have identified a gene switch that rewires heart muscle cells in infants with AARS2-related cardiomyopathy, a rare inherited condition that is typically fatal before a child's first birthday. The discovery sheds new light on the molecular mechanisms driving the disease, for which no treatment currently exists. The findings open a potential therapeutic avenue for one of medicine's most urgent and underserved cardiac conditions.

The AGA is calling for stronger prevention strategies alongside improved early-detection tools for hepatocellular carcinoma, which is the leading cause of cancer death among cirrhosis patients. With HCC ranking third globally in cancer-related mortality, the guidance underscores that upstream intervention — not just better treatment — is where the battle must be won.
Read article →Researchers at NYU Langone Health have found that the unique bacterial composition of a patient's gut can predict melanoma recurrence after surgery and immunotherapy with up to 94% accuracy. The study suggests that microbial profiles could serve as a powerful diagnostic tool for identifying which patients face the highest relapse risk. If validated at scale, this discovery could fundamentally reshape how oncologists monitor and manage melanoma patients post-treatment.
