science 🔬 AI can estimate organ age from blood samples
New AI research shows that biological age can be estimated for 40 tissue types across 29 organs. The study used tissue images and paired blood gene expression data from 983 individuals. Models predicted the biological age of tissue within about 4.88 years on average. Blood tests alone detected accelerated organ aging in people with conditions like Alzheimer’s disease and stroke. However, the research cannot yet confirm if these aging signals appear before disease development. 🩺
