Researchers have retracted a biology paper that included an image mismatch — despite the fact that, as they claim, another image in the same paper confirms the original findings.
The authors say they plan to resubmit the paper with the corrected figure panel.
The second to last author — Carlo Croce, chair of the department of cancer biology and genetics at The Ohio State University — told us he believes there’s more to the retraction than what the notice says. Specifically, he said that the paper includes an image from a previous paper by the same authors, which he called “fraud.”
Here’s the latest retraction notice, published in Cell Death and Differentiation:
Around two years ago, when mathematics researcher Jean Ecalle submitted a paper to Acta Mathematica Vietnamica, he saw that he had the option of making the paper open access. So he checked a box on the submission form — which included a mention of the fees that he apparently missed — and didn’t think anything of it.
The paper “Eupolars and their Bialternality Grid” appeared online in October, 2015.
So Ecalle was quite surprised when, sometime later, he received an email from a representative of the publisher saying he owed 2,640 Euros. He responded in January 2016, guessing what the fees might stem from:
In 2011, authors of a Nature letter caught some flak for issuing a lengthy correction to a neuroscience paper that had raised eyebrows within days of publication — including some suggestions it should be retracted.
The correction notice, published months after the original letter, cited errors in image choice and labeling, but asserted the conclusions remained valid.
Now, those conclusions appear up for debate. In a recent Nature Brief Communications Arising (BCA) article, a team that raised concerns about the paper five years ago says they are unable to reproduce the results. But the authors of the original paper aren’t convinced: They argue that the BCA fails to cite important evidence, has a “complete absence or low quality of analysis,” and the scientists disregard some of their data.
The move prompted the journal to also retract an associated News & Views article.
After a series of documentaries prompted his former employer, Karolinska Institutet (KI), to reopen a misconduct investigation against him, KI has today released one verdict regarding a 2014 Nature Communications paper: guilty.
KI said it is contacting the journal to request a retraction of the paper, which has already been flagged with an expression of concern.

The EOC mentions the lack of reproducibility of the gene-editing technique, known as NgAgo. Alongside it, the journal has published a correspondence which includes data from three separate research groups that cast doubt on the original findings.
According to a spokesperson for the journal, some of the paper’s authors have objected to the decision to issue an EOC.
Earlier this month, we reported on a letter signed by 20 researchers which also raised concerns about the genome-editing activities of NgAgo — and alleged the lab that produced the initial results turned away investigators when they attempted to validate the tool in mammalian cells.
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:
Nature Communications has issued an expression of concern for a 2014 paper by beleaguered surgeon Paolo Macchiarini, citing concerns over whether the paper accurately reports the experiments that were carried out.
According to the notice, Macchiarini, a former rising star in the field of transplant medicine, agrees with the expression of concern. Three of his 22 co-authors have objected.
“Experimental orthotopic transplantation of a tissue-engineered oesophagus in rats” describes transplanting an esophagus into rats that was seeded with their own stem cells, and notes that all animals survived the study period (14 days), and gained more weight than rats given a placebo operation. It’s a topic Macchiarini has made famous, as the first surgeon to perform a similar procedure with a human tracheal transplant. But he’s faced charges of misconduct in the last few years, resulting in his dismissal from Karolinska Institutet (KI).
