Superconductor highs and lows.

Physicist Ranga Dias of the University of Rochester made bold claims about creating room-temperature superconductors, but three of his papers have been retracted, raising suspicions about his work and the field of high-pressure physics. However, other research on high-temperature superconductors is considered solid, with multiple groups replicating key results and theoretical calculations aligning with experiments. Scientists are now working on new ways to identify superconductivity, debating standards for claiming superconductivity, and discussing data sharing norms to prevent future questionable claims. Despite the controversy, progress is being made in creating superconductors that require less chilling, and new materials and structures are being explored. [Extracted from the article]
