The record for high-temperature superconductivity has been smashed again

Chemists found a material that can display superconducting behavior at a temperature warmer than it currently is at the North Pole. The work brings room-temperature superconductivity tantalizingly close.
by Emerging Technology from the arXiv

Superconductivity is the weird phenomenon of zero electrical resistance that occurs when some materials are cooled below a critical temperature. The best superconductors have to be cooled with liquid helium or nitrogen to get cold enough (often as low as -250 °C or -480 F) to work. The holy grail for researchers is the idea that…
