'Smoking gun' may help solve mystery of high-temperature superconductivity

Scientists report finding a 'smoking gun' that could explain the mechanism behind high-temperature superconductivity. The phenomenon has eluded explanation for decades despite its use in powerful MRI magnets, efficient power transmission and ultrasensitive sensors.

• The finding may explain the mechanism of high-temperature superconductivity
• The phenomenon has defied explanation for decades
• Superconductors are already used in MRI, power grids and sensors
