A major physics journal is retracting a two-year-old scientific paper that described the transformations of a chemical compound as it was squeezed between two pieces of diamond. Such an esoteric finding — and retraction — would not typically garner much attention. But one of the leaders of this research is Ranga Dias, a professor at the University of Rochester in New York who made a much bigger scientific splash earlier this year, touting the discovery of a room-temperature superconductor. While Dr. Dias continues to defend the work, to some scientists, there is now clear evidence of misconduct. “There’s no plausible deniability left,” said N. Peter Armitage, a professor of physics and astronomy at Johns Hopkins University in Baltimore who is among the scientists who have seen the reports. “They submitted falsified data. There’s no ambiguity there at all.” Related: The Scientific Breakthrough That Could Make Batteries Last Longer and Room-Temperature Superconductor Discovery Meets with Resistance

Seven major automakers announced a plan on Wednesday to nearly double the number of fast chargers in the United States in an effort to address one of the main reasons that people hesitate to buy electric cars. The carmakers — BMW Group, General Motors, Honda, Hyundai, Kia, Mercedes-Benz Group,, and Stellantis — will initially invest at least $1 billion in a joint venture that will build 30,000 chargers on major highways and other locations in the United States and Canada. The United States has about 32,000 fast chargers — those that can replenish a drained battery in 10 to 30 minutes. The chargers will have plugs designed to use the connections used by most carmakers other than Tesla, as well as the standard developed by Tesla that Ford, G.M.,, and other companies have said they intend to switch to in 2025.
