Physicists discover a new switch for superconductivity
Under certain conditions — usually exceedingly cold ones — some materials shift their structure to unlock new, superconducting behavior. This structural shift is known as a "nematic transition," and physicists suspect that it offers a new way to drive materials into a superconducting state where electrons can flow entirely friction-free.
