Ranga Dias

Physicist (University of Rochester) whose two headline claims of room-temperature superconductivity — carbonaceous sulfur hydride (2020) and nitrogen-doped lutetium hydride (2023) — were both later retracted by Nature following forensic critiques of the underlying susceptibility data. Matters to this vault as the central subject of its data-forensics/retraction cluster: he and his coauthors maintained the raw data supported the original claims even as Nature's editors and outside critics converged independently on the same specific mechanism (an undisclosed, non-reproducible background-subtraction procedure).
