SALT LAKE CITY -- The University of Utah is investigating allegations chemical engineering researchers may have altered microscopic images in a research paper to prove their theory was correct.
The Salt Lake Tribune reports the paper was published in June, but the research journal Nano Letters retracted it on Aug. 15, citing concerns over data integrity.
The probe into the research was started after a blog questioned microscopic images in the article, alleging they appear to have been digitally manipulated.
University Health Care's medical ethics chief Jeffrey Botkin says the school is also investigating claims of altered images in another paper published by the same researchers.
Earlier this month, the school announced it found an internal medicine lab had "recklessly" manipulated information in 11 papers over a five-year period, including doctored images and fabricated data.
