Nature has retracted a study claiming to have created a room-temperature superconductor due to concerns about the reliability of the data presented. Eight of the study's authors requested the retraction, stating that the published paper did not accurately reflect the materials, experimental measurements, and data-processing protocols. This is the second retraction in two years for physicist Ranga Dias and his team, who have faced allegations of misconduct and plagiarism. #science #nature #superconductor
