TechnologyScientists Find 'On-Off Switch' for Superconductivity in Twisted GrapheneAn Ohio State team can flip superconductivity on and off in twisted bilayer graphene by tuning its surroundings — a step toward the long-sought goal of room-temperature electronics with zero energy loss.
TechnologyFinland Builds Sensor That Detects Energy Below a ZeptojouleResearchers at Aalto University built a calorimeter that can detect energy pulses smaller than 0.83 zeptojoules — a milestone for quantum computing and the hunt for dark matter.
