About The Study: In this cross-sectional study of U.S. participants, intentional searches for gun-related harm content were reported by a notable minority of youth and young adults, especially those facing structural disadvantages and mental health distress. Public health strategies that combine digital interventions with structural reforms offer promising avenues to reduce gun-related harm among vulnerable populations.

About The Study: In this study, AI applications were associated with increased accuracy and confidence of consumer understanding of skin concerns, with the degree of improvement in accuracy varying by the accuracy of presented conditions; benefits further improved when predictions were as accurate as possible. Imperfect guessing accuracy when predictions presented matched dermatologist differentials highlighted the need for further design improvements (such as the condition information presented) to help consumers better understand skin conditions.

Applying new analytic methods to nearly 16,000 ancient genomes reveals natural selection has acted on hundreds, not dozens, of genes in West Eurasia over the last 10,000 years. More than half of the genes have known links to disease risk and other traits today, although it’s not yet clear what made each gene advantageous in prehistoric contexts. The work demonstrates the power of ancient DNA to illuminate human biology and medicine in addition to history.

About The Study: The findings of this study suggest that a community-based point-of-care hepatitis C virus (HCV) RNA testing program was feasible and was associated with a high percentage of same-day treatment for American Indian and Alaska Native participants. This study supports expanding point-of-care HCV RNA testing and integrated treatment to advance HCV elimination.

A California jury awarded $6 million in a social media addiction case, a ruling Meta and Google plan to appeal, spotlighting growing legal and scientific debate. MSU researcher Dar Meshi says excessive use is linked to harm in some studies, but evidence is largely correlational and experts still disagree on whether it qualifies as a clinical addiction.
