Researchers at the University of California, Irvine have discovered how atomic-scale mechanics enhance superconductivity in iron selenide (FeSe) films on strontium titanate (STO) substrates. Using advanced vibrational spectroscopy, they observed new phonons at the interface, which couple with electrons to increase the superconductivity transition temperature to 65 Kelvin, the highest for its class. This study, published in Nature, highlights the role of electron-phonon coupling and interface uniformity in superconductivity, paving the way for scalable superconductor applications in quantum computing and other fields.

Physicist Ranga Dias has been terminated from the University of Rochester following a formal investigation that concluded he engaged in research misconduct related to his controversial claims of high-temperature superconductivity. Dias' papers, which initially reported breakthroughs in superconductivity at high temperatures, were retracted due to data reliability concerns. Despite Dias' denial of wrongdoing and a dismissed lawsuit claiming bias in the investigation, the university's decision was upheld by the Board of Trustees.
