Many other scientists greeted the announcement with skepticism because an earlier Nature paper by Dr. Dias describing a different and less practical superconducting material had already been retracted. The university had previously conducted three preliminary inquiries into Dr. Dias’s research and decided the concerns did not warrant further scrutiny. On Tuesday, Dr. Hamlin said he was pleased that the journal had taken his concerns seriously. He said there were two additional instances of apparent data duplication in Dr. Dias’s work that he hoped would also be reviewed. One involves another Nature paper; the other is what Dr. Hamlin describes as a duplication of data in Dr. Dias’s thesis.
