Podcast: Reading pain from the brains of infants, modeling digital faces, and wifi holograms

This week, we discuss the most accurate digital model of a human face to date, stray Wi-Fi signals that can be used to spy on a closed room, and artificial intelligence that can predict Supreme Court decisions with Online News Editor Catherine Matacic.

Caroline Hartley joins Sarah Crespi to discuss a scan that can detect pain in babies—a useful tool when they can’t tell you whether something really hurts.
