The beat goes on for room-temperature superconductivity, thanks to a new experiment that replicates contested results.
When researchers announced in 2020 that a sample made of hydrogen, sulfur and a bit of carbon, dreams of room-temperature superconducting seemed to be on the verge of coming true. One hitch was that the material had to be under enormous pressures, about 2.6 million times atmospheric pressures — roughly the pressure found in parts of Earth’s core. Still, the discovery hailed a potential scientific and technological revolution.
The new experiment isn’t a duplicate of the one reported in the retracted paper, but the researchers replicated a portion of their research that raised red flags in the scientific community. “I didn’t know it would be retracted, but was hoping it would be retracted,” says Hirsch, who was not affiliated with either the original or new experiment. He says he asked the authors for the raw data from the earlier study one month after it was published, but he was refused. “The authors said, ‘No we cannot give you the data because our lawyers said that it would affect our patent rights.’”, Hirsch eventually got the numbers. What he saw disturbed him.
