Summary

Story summary

Researchers report superconductivity in the mercury-based compound Hg-1223 at 151 kelvins under atmospheric pressure, a new record per the Proceedings of the National Academy of Sciences.
They used pressure quenching to retain the superconducting state after releasing the applied pressure.
The result surpasses the previous 133 kelvin record set in 1993.
The findings point toward a potential path to room-temperature superconductivity and could transform energy transmission and medical imaging.
