Last week, we learned a 2016 paper heavily discussed on PubPeer might be retracted — today, we learned that Nature Cell Biology has indeed pulled the paper, citing inappropriate image modifications.
As we reported last week, a comment on PubPeer flagged as coming from an author said they had requested a retraction. A representative of National Taiwan University (NTU) told us the first author had resigned, and the paper was under investigation — an investigation which included the last author, a prominent researcher who is also a vice president at another institution in Taiwan.
A new letter signed by 20 researchers is casting additional doubts on the validity of a potentially invaluable lab tool — and alleges the lab that produced the initial results turned them away when they tried to replicate its findings in mammalian cells.
Although a representative of the journal wouldn’t confirm to us that the authors had requested a retraction, the comment on PubPeer says the paper contains several figures that were “inappropriately manipulated” by the first author.
A Nature Cell Biology article on insulin regulation has been retracted after scientists noted that the antibodies used in their research were not as specific as they had previously believed.
The notice is clear on the problems with the science, which together “call into question the main conclusions of the paper.” Three of the paper’s five authors were employed at Novartis at the time of publication.
A former Vanderbilt University biomedical engineer committed fraud on a massive scale, according to a new Office of Research Integrity (ORI) report.
Igor Dzhura is banned from receiving federal funding for three years, and is retracting six papers, which have been cited more than 500 times. Since leaving Vanderbilt, he has worked at SUNY Upstate Medical University, and now works at Novartis.
