So for now, the dream of room-temperature superconductors is on pause. But despite LK-99’s unfortunate fate, the dream has never been so tantalizing.

A superconductor at both room temperature and ambient pressure, the material called LK-99 shows promise—but fellow scientists are skeptical.

Claims of a room-temperature superconductor went viral last week. Here's everything we know.

Room-temperature superconductors would revolutionize nearly every technology on Earth, but the path toward that “holy grail” of materials is a long one.
