Twisted graphene reveals a hidden superconductivity switch

Scientists have uncovered a surprising new way to control superconductivity — the mysterious phenomenon where electricity flows with zero energy loss. By pairing twisted layers of graphene with a synthetic diamond material, researchers were able to effectively switch superconductivity on and off by tweaking how electrons interact with their surroundings. Even more intriguing, the material behaved in ways that defied the rules of conventional superconductors, hinting at an entirely new kind of physics.
