The race is on to make the first room temperature superconductor

In August and September this year two papers appeared on the arXiv preprint server that brought scientists closer to a discovery craved for many decades: room temperature superconductivity. Different international teams published preliminary measurements of yttrium superhydrides, which only form at very high pressures. This time, they could not produce YH₁₀, which researchers have predicted to be superconducting at temperatures below 326K, or 53°C. But the fact that such predictions are guiding experimentalists shows that superconductivity science is reaching new levels. These calculations are now leading scientists to exciting new frontiers, where tough questions await them.
