A new AI system that predicts the health spans of mice could help develop life-extension interventions for humans, according to the tool’s inventors. The system analyzes established measures of frailty to gauge a mouse’s chronological age and their so-called biological age — the condition of their physical and mental functions. It was created by researchers from Harvard Medical School’s Sinclair Lab, who say it’s the first study to track a mouse’s frailty for the duration of its life. They plan to use the predictions to quickly test interventions intended to extend the mice’s lives and move towards doing the same…
