Researchers from Cambridge showed that superconductors could be used as an energy-efficient source for spintronics devices - this was not believed to be possible by most researchers. Superconducting spintronics devices may enable powerful circuits that consumer very little power (in fact superconductors offer 100% energy efficiency):
