Google has developed a way to predict your risk of a heart attack just by scanning your eye

Your eyes might be the perfect windows into your heart. At least, they're windows that Google-created artificial intelligence software can use to calculate your risk factors for heart disease. According to a study recently published in the Nature Biomedical Engineering journal, an AI algorithm created by Google AI and Verily Life Sciences (an Alphabet subsidiary that spun off from Google) can predict whether a patient is likely to suffer a major cardiovascular event like a heart attack or stroke within five years, based on a photo of their retina. So far, the predictions work about as well as presently accepted methods that are more invasive, according to the study. The fact that disease can be spotted in the retina isn't a surprise. To mimic that ability, the Verily and Google researchers trained AI software to identify cardiovascular risks by having the system analyze retina photos and health data from 284,335 patients.
