Teaching computers to create an early warning system for kidney disease

About twice every hour, all of the blood in our bodies filters through our kidneys, removing waste and excess water to produce urine. But this important kidney function is irreversibly compromised in about 20 million Americans by chronic disease, most often related to poorly controlled diabetes and high blood pressure. In many cases, modern medicine does nothing to slow kidney disease for one very simple reason—most who are affected don't know it until it's already too late.
