Food timing may shape how T cells respond to infection and therapy6:02 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 mice4:58 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 appear4:27 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 test3:23 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 obesity22:36 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. Pathogens drive inflammation by reprogramming host cell metabolic processes22:36 An intestinal pathogen reshapes the gut environment to fuel its own colonization and cause diseases, a multi-institutional team including researchers at Vanderbilt Health has discovered. Sickness behavior may be a coordinated whole organism immune strategy22:36 Symptoms such as fatigue, loss of appetite, altered sleep, and social withdrawal are often treated as inconvenient side effects of infection. Strategic social network targeting produces greatest reduction in smoking22:36 Targeting only a small group of well-connected individuals with smoking reduction interventions produces the largest reductions in smoking, researchers report. Dangerous water bead ingestions increase among young children22:36 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. Liquid biopsy predicts immune response in high-risk breast cancer patients22:36 Immunotherapy has become a standard of care in treating high-risk, early-stage breast cancers, yet it has had limited success in shrinking tumors. |
