UN Chief and Red Cross Renew Call for International Rules on Autonomous Weapons

UN Secretary-General António Guterres and the International Committee of the Red Cross (ICRC) have jointly renewed their appeal for international rules governing lethal autonomous weapons systems (LAWS), highlighting growing concerns about the ethical implications of AI-driven combat. Speaking ahead of a scheduled review conference, Guterres emphasized the urgent need for

FDA Opens Public Comment Period on Generative AI Medical Device Framework

The U.S. Food and Drug Administration (FDA) has taken a significant step toward formalizing oversight of generative AI (GenAI) in medical devices by publishing a draft framework and opening a public comment period. The framework addresses a growing category of software-based medical tools that use generative AI to perform

FDA Clears AI Tool for Pulmonary Hypertension Detection via Standard ECGs

The U.S. Food and Drug Administration has granted clearance to an artificial intelligence software designed to identify signs of untreated pulmonary hypertension using signals from standard 12-lead ECGs—a diagnostic test commonly available in clinical settings. Pulmonary hypertension is a condition characterized by high blood pressure in the arteries

Guardrails Needed: Addressing AI Misinterpretation of Biomedical Research

A new perspective piece published in Nature Digital Medicine examines the growing challenge of AI systems misinterpreting scientific literature, particularly in the biomedical domain. The issue stems from the inherent complexity of scientific papers—dense language, nuanced statistical claims, and contextual dependencies that current AI systems struggle to parse accurately.

Study Reveals Common Medications May Reshape Gut Microbiome for Years

The Hidden Legacy of Common Medications A growing body of evidence suggests that the medications many people take routinely may leave a lasting imprint on their gut bacteria. While antibiotics have long been known to disrupt the microbiome, new research indicates that several other commonly prescribed drug classes can reshape

The Sweet Spot for Sleep: New Research Finds 6.4 to 7.8 Hours May Slow Biological Aging

Sleep duration appears to influence how quickly the body ages biologically, according to a comprehensive review of multiple aging clocks. Researchers examining 23 different biological aging metrics found that the lowest levels of cellular and systemic aging were associated with sleeping approximately 6.4 to 7.8 hours per day.

Motor Neurons Found to Play Active Role in Organizing Movement Sequences

Traditionally, motor neurons have been understood as simple relay units, passing commands from the brain to muscles to produce movement. However, a new study using fruit flies challenges this view by demonstrating that motor neurons engage in two-way communication with the central nervous system. Researchers found that motor neurons send
