Scientists at Stanford University used advanced technology to study 6,000 eye proteins and predict people's ages using artificial intelligence.
They discovered proteins related to Parkinson's disease in the eyes, which could help diagnose the disease earlier.
The eye, like a live camera, allowed researchers to see diseases as they happen and understand what's occurring at a tiny, molecular level.
Instead of traditional tissue samples, they used liquid samples from the eyes to identify proteins and specific cell types, making it easier to diagnose diseases.
This research suggests that different body parts might age at different rates, which could lead to better and more precise medical treatments.
This study was published in the journal "Cell" and could change how we understand and treat diseases.
