Researchers at the George Washington University have found out that lanthanum hydride nearly at room temperature (but under enorme pressure) shows superconductivity.
Who would have thought that Metal Hydrides would do such thing?!

Researchers discover new evidence of superconductivity at near room temperature
"We believe this is the beginning of a new era of superconductivity," Russell Hemley, a research professor at the GW School of Engineering and Applied Science, said. "We have examined just one chemical system – the rare earth La plus hydrogen. There are additional structures in this system, but more significantly, there are many other hydrogen-rich materials like these with different chemical compositions to explore. We are confident many other hydrides—or superhydrides—will be found with even higher transition temperatures under pressure."
