Gravity-Defying Materials, Microsoft's Start Menu Surprise, and Lunar Robot Canines

In today's episode of Discover Daily by Perplexity, we discuss a new material developed by researchers in Japan that enables stable magnetic levitation without requiring an external power source. The centimeter-sized thin square plate, made from graphite coated with silica, hovers above a grid of magnets by harnessing the diamagnetic properties of graphite. This frictionless, self-sustaining floating platform technology could lead to the development of highly sensitive sensors for measuring f...
