Human urine is a treasury of health data. It can offer clues to more than 600 illnesses and health conditions; testify to a person’s exercise habits, sleep patterns, and other issues; and spot changes quickly to flag danger signs.
But how to capture those sudden hints of illness?
Leave it to scientists at the University of Wisconsin. They’ve designed a toilet with a built-in portable mass spectrometer that can grab urine samples and test them automatically to spot chemical signatures of health changes.
