Researchers report being beaten to findings by AI systems twice in five weeks. Tristan Buckmaster posted progress on the Navier–Stokes problem on 7 September. OpenAI announced its agents had solved it the next day. Anthropic later said its Claude model found CRISPR-like DNA in viruses. A PhD student had been studying the same patterns for years. Some scientists now avoid sharing work with AI tools. Sandra Laurentino strips code of real names before using AI. Samuel Mehr bans students from uploading protected data to commercial models. OpenAI and Anthropic deny using uploaded work for training. The disputes have not restored trust among researchers.
