Superconductors inch upward — Science Information, March 16, 1974
Superconductivity, the property by which sure metals lose all their electrical resistance, can be a grand factor to make use of technologically had been it not for the acute refrigeration crucial. Each superconductor has a transition temperature above which it turns into an abnormal conductor. Most transition temperatures are close to absolute zero. [Scientists] are discovering metals with larger transition temperatures.

Transition temperatures proceed to creep upward. In 2018, physicists reported {that a} compound of lanthanum and hydrogen beneath excessive strain confirmed indicators of superconductivity as much as about −20° Celsius — the best for any superconductor (SN: 10/13/18, p. 6). However the squeeze and relative chill makes these supplies impractical for widespread use, so the hunt for a fabric that superconducts at room temperature and nearer to atmospheric strain continues. A debunked 2023 declare for such a fabric has some scientists advocating for brand new requirements for figuring out superconductivity (SN: 12/16/23 & 12/30/23, p. 22).
