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.
In a letter published this week in Protein & Cell, the researchers add their voices to the critics of the gene-editing technique, first described earlier this year in Nature Biotechnology.
The researchers outline their attempts to apply the technique — known as NgAgo — to a variety of cell types, which fell short:
A Nature Cell Biology paper published only a few months ago by prominent researchers in Taiwan has sparked a heated discussion on PubPeer, which now includes a comment allegedly from an author saying they have requested its retraction.
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.
Here’s the full comment on PubPeer, tagged as coming from one of the authors of the paper:
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.
According to the ORI, Dzhura was a busy boy at Vanderbilt, faking images and drastically inflating the number of experiments he conducted by duplicating computer files and saving them in nested folders. The total body count from his work includes: Read the rest of this entry »
Former University of Tokyo researcher Shigeaki Kato has notched his 26th, 27th, and 28th retractions, all in Nature Cell Biology. The three papers have been cited a total of 677 times.
