Food timing may shape how T cells respond to infection and therapy

Short-term nutritional state can reshape T cell metabolism, with post-meal lipid metabolism enhancing T cell metabolic capacity, cytokine production, and persistence after activation. The study identifies triglyceride-rich chylomicrons as key drivers of this effect, suggesting nutritional timing may matter for immune monitoring, vaccination research, and cell-therapy manufacturing.

Five-target drug beats GLP-1/GIP therapy in obese diabetic mice

A Nature study reports a single-molecule GLP-1–GIP–lanifibranor quintuple agonist that targets incretin receptor-expressing cells while activating PPARα/γ/δ pathways. In obese and insulin-resistant mice, the compound reduced body weight, food intake, and hyperglycaemia more effectively than semaglutide or GLP-1R–GIPR co-agonism, while remaining a preclinical finding.

New genetic risk report reveals hidden heart disease risk before symptoms appear

Researchers developed and externally validated integrated polygenic risk scores for eight cardiovascular conditions using large U.S.-based biobank data. The clinically orderable report may help identify inherited cardiovascular risk that traditional clinical markers can miss, although broader prospective validation is still needed.

AgentClinic puts medical AI through a more realistic diagnostic test

AgentClinic is a multimodal benchmark that tests clinical AI agents in simulated, dialogue-driven diagnostic settings rather than static medical question-answer formats. The study found that model performance varied sharply by tool use, language, bias, image handling, and patient-agent interactions, highlighting the need for more realistic AI evaluation before clinical deployment.

New screening tool predicts health risks for people living with obesity

A simple tool, developed by researchers at Queen Mary University of London and the Berlin Institute of Health at Charité, could help identify which people living with obesity or overweight are most likely to develop serious obesity-related conditions such as type 2 diabetes and heart disease.

Dangerous water bead ingestions increase among young children

A new study reveals that ingestions of water beads by young children have surged in recent years. Researchers at the Center for Injury Research and Policy of the Abigail Wexner Research Institute at Nationwide Children's Hospital and the Central Ohio Poison Center analyzed calls to U.S. poison centers and found an alarming 6,532% increase in the rate of reported water bead ingestions among children younger than 6 years from 2019 to 2023, followed by a 24% decrease from 2023 to 2024.

UCLA researchers build programmable artificial organelles using RNA

Just as the human body relies on organs such as the heart or liver for essential functions, cells depend on their own tiny organs, or organelles, to carry out vital tasks, including transporting nutrients, removing waste and regulating genetic activity.
