The previous ambient-pressure mark of 133 K was held by a mercury-based copper-oxide ceramic. The findings were published in the Proceedings of the National Academy of Sciences.\n\nThe key advance is not just the higher temperature but how it was reached. The team demonstrated that the enhanced superconducting properties usually only seen under crushing pressure can be preserved at ambient pressure, removing one of the biggest obstacles standing between lab demonstrations and real-world use.\n\nThe stakes are large. Roughly 8 percent of electricity is lost as heat during transmission, and Chu noted that conserving that energy would mean billions of dollars in savings. Higher-temperature superconductors could enable more efficient power grids, better energy storage, faster electronics, and improved medical imaging."}}
