At the end of a long week filled with too many deadlines and too little sleep, you wake up one morning woozy with a strange pain in your arm. You call your doctor, and she asks you a series of questions over the phone. She then tells you to go to the emergency room pronto: "I suspect you're having a heart attack." The doctor reached that conclusion not by simply making an educated guess, but by evaluating the data and using deductive reasoning. In medical school, physicians learn to estimate probabilities of disease based on symptoms, patient history, examination findings and labs or images.

An artificial intelligence-powered tool that transforms pixelated images into clear photos has been accused of racial bias. Called Face Depixelizer, the tool was released on Twitter for users to test, who found the technology is unable to process Black faces properly. The tool transformed a pixelated image of Barack Obama into a a white man and other examples included Representative Alexandria-Ocasio Cortez and actress Lucy Liu - all of which were reconstructed to look white. The Face Depixelizer is based on an AI tool developed by a team at Duke University, which uses a method called PULSE that searches through AI-generated images of high-resolution faces to match ones that look similar to the input image when compressed to the same size.
