A U of R statement did not say whether the scientist, Ranga Dias, resigned or was fired.

Ranga Dias of the University of Rochester gained worldwide acclaim with a pair of papers in 2020 and 2023 in Nature describing two compounds that appeared to conduct electricity without resistance near ambient temperature.

In the 8 March issue of Nature, researchers led by Ranga Dias, a physicist at the University of Rochester, reported making a blue crystalline compound that when squeezed to moderate pressures turned red and exhibited a long-sought property: It conducted electricity without resistance at room temperature.

Led by physicist/engineer Ranga P. Dias, they reported in an article in Nature the discovery of a room-temperature superconductor — a material that can conduct electricity with no loss of efficiency from friction and no production of heat.

It was the second superconductor paper involving Ranga P. Dias, a professor of mechanical engineering and physics at the University of Rochester in New York State, to be retracted by the journal in just over a year.
