Aged immune cells may drive memory decline by releasing a brain-aging protein
3+ hour, 5+ min ago (134+ words) A mouse study reveals how aging immune cells may impair memory outside the brain, showing that blocking CD8+ T cell activity or their secreted factor, granzyme K, helped restore cognitive performance in aged animals. Study: Aged circulating CD8+ T cells and their…...
AI eye scans reveal who may be at higher risk of osteoporosis
4+ hour, 9+ min ago (579+ words) A new study suggests that AI-powered retinal imaging may capture systemic aging signals linked to weaker bones, offering a potential low-cost route to identify people who may need formal osteoporosis assessment before fractures occur. Study: Retinal biological age correlates with…...
AI beats primary care doctors in simulated diagnosis study using images and ECGs
4+ hour, 50+ min ago (651+ words) A state-aware medical AI system interpreted images, ECGs, and clinical documents during live diagnostic chats, outperforming primary care physicians in simulated consultations while raising urgent questions about how such tools should be tested before real-world care. Study findings revealed that…...
