Research identifies blind spots in AI medical triage

The Mount Sinai Hospital / Mount Sinai School of Medicine
Peer-Reviewed Publication

ChatGPT Health, a widely used consumer artificial intelligence (AI) tool that provides health guidance directly to the public—including advice about how urgently to seek medical care—may fail to direct users appropriately to emergency care in a significant number of serious cases, according to researchers at the Icahn School of Medicine at Mount Sinai. The study, fast-tracked in the February 23, 2026 online issue of Nature Medicine [https://doi.org/10.1038/s41591-026-04297-7], is the first independent safety evaluation of the large language model (LLM)-based tool since its January 2026 launch. It also identified serious concerns with the tool’s suicide-crisis safeguards.

Researchers discover how an anti-obesity drug improves metabolism beyond weight loss

University of Barcelona
Peer-Reviewed Publication

Tirzepatide is one of the drugs that has revolutionized the treatment of obesity and other conditions such as diabetes in recent years. Despite its clinical success, its precise molecular and cellular mechanisms are still not fully understood. A study in mice shows that the drug has a direct impact on improving metabolism by activating brown adipose tissue, a type of fat specialized in energy expenditure. According to the researchers, these results help to better understand the mechanisms of action of tirzepatide and open up new avenues for developing more comprehensive treatments for obesity and other metabolic diseases.

A gold-standard survey of the American mood

PNAS Nexus
Peer-Reviewed Publication

American reports of individual well-being have remained relatively stable over decades, but confidence in the nation has sharply declined. James N. Druckman and colleagues analyzed long-term survey data from two National Science Foundation-supported infrastructure projects: the General Social Survey and the American National Election Studies. The analysis examined trends in economic satisfaction, health, happiness, satisfaction with democracy, affective polarization, political efficacy, and institutional confidence.

How Japanese medical trainees view artificial intelligence in medicine

Juntendo University Research Promotion Center
Peer-Reviewed Publication

Artificial intelligence (AI) is rapidly reshaping medicine, yet how future doctors feel about AI remain poorly understood in Japan. The newly developed 12-item attitudes towards artificial intelligence (ATTARI-12) scale has shown good validity and reliability, prompting researchers to create a Japanese version, J-ATTARI-12. Validated among medical students and residents across Japan, J-ATTARI-12 offers a structured way to understand readiness, concerns, and acceptance of AI in medical training and practice.
