Community workers sound alarm on mental health crisis for Venezuelan migrants

A new study reveals growing concern among community workers in Nariño, Colombia, about the lack of mental health support for Venezuelan migrants, especially those traveling without legal status. The study, published in PLOS Mental Health, comes as Colombia has taken steps to expand health care access to some of the 2.86 million Venezuelans in the country, including offering temporary protection status.

Flavored tobacco bans linked to lower youth vaping in California

Researchers from the University of California San Diego have found that local sales bans on flavored tobacco in California are associated with reduced youth vaping over time without increasing cigarette smoking. The findings, based on an analysis of more than 2.8 million middle and high school students, were published April 10, 2026, in JAMA Health Forum.

Reprogramming regulatory T cells could help immunotherapy work in pancreatic cancer

Researchers at Oregon Health & Science University have uncovered a key reason why immunotherapy has largely failed in pancreatic cancer—and identified a promising strategy to overcome that resistance. The study, published in the journal Immunity, shows that pancreatic tumors actively reshape their immune environment by co-opting regulatory immune cells that normally shut down tumor-killing cells. By reprogramming those cells, the research reveals a potential pathway to make immunotherapy effective against one of the deadliest and most treatment-resistant cancers.

New guidance on adenomyosis, an overlooked uterine condition affecting 1 in 3 women

A University of Hawaiʻi at Mānoa physician is working to change how a common but often overlooked gynecologic condition is diagnosed and treated. Kimberly Kho, who holds the nation's first professorship in advanced gynecological surgery in the John A. Burns School of Medicine (JABSOM), authored a clinical expert series review on adenomyosis in Obstetrics & Gynecology. The publication places Kho among a select group of internationally recognized experts in women's health.

Hippocampal pathways once thought separate converge to integrate ‘where’ and ‘why’ in reward processing

New research from the University of Maryland, Baltimore County (UMBC) reveals how two different parts of the brain's memory center team up in a key reward region to help mice—and likely humans—combine memories of places and contexts with the drive to pursue rewards. The findings offer fresh insight into how the brain integrates information about "where" and "what feels good" to guide everyday decisions, such as heading to a favorite restaurant to meet friends or seeking out rewarding experiences. Specifically, this discovery, published in the Journal of Neuroscience, shows that inputs from the dorsal and ventral hippocampus converge on the same individual neurons in another brain region, the nucleus accumbens, where they interact in ways that amplify each other's effects.
