A new hydrogen-rich compound may be a record-breaking superconductor

Material appears to transmit electricity without resistance at a relatively high temperature

HELLA HYDROGEN  The compound LaH10 is composed of 10 hydrogen atoms (pink) for each lanthanum atom (green). This hydrogen-rich material was predicted to exhibit superconductivity, evidence for which has now been found.

Superconductors are heating up, and a world record-holder may have just been dethroned.
