Researchers at the Max Planck Institute for Chemistry in Mainz, Germany, have recently confirmed a record-setting transition temperature of 203 K (-70° C) into the superconducting state of a hydrogen-based compound when it is squeezed under extreme pressures of around 150 GPa, or nearly 1.5 million atmospheres [Nature 2015]. While this result represents the culmination of a long history of searching for ultra-high-temperature superconductivity in metallic hydrogen, first predicted by Neil Ashcroft, the experimental realization blows the top off an old myth that conventional phonon-based superconductivity would be limited to much lower temperatures.
