Two more retractions for stem cell researcher appealing her dismissal

Susana Gonzalez

Susana Gonzalez, a rising star in stem cell research, has had a rough year.

In addition to being fired from her former research institute (which she is now appealing), one of her grants (totaling nearly 2 million Euros) was suspended. Most recently, she has received two new retractions in Nature Communications over figure duplications and missing raw data. By our count, she has a total of three retractions.

Both of the new notices say the papers contained figures duplicated in other papers by Gonzalez, and neither includes Gonzalez among the list of co-authors who agreed to the retraction.

Gonzalez was dismissed from her position at the National Center for Cardiovascular Research (CNIC) in Spain last February over allegations of misconduct. According to the head of basic research at CNIC, Gonzalez is still embroiled in a legal battle with the Center over her dismissal. Vicente Andrés could not go into detail because of the ongoing litigation, but he told us: Continue reading Two more retractions for stem cell researcher appealing her dismissal

Huh? Cancer paper gets retracted because of its correction

Here’s a rather odd case: When readers raised issues about some of the images in a 2008 cancer paper, the authors issued a correction last year. But when readers asked additional questions about the corrected images, the authors decided to retract the paper entirely, along with its correction.

Both the original and corrected versions were questioned on PubPeer.

Here’s the retraction notice for the 2008 article “PRIMA-1MET induces mitochondrial apoptosis through activation of caspase-2,” published in Oncogene, which includes a link to the July 2016 correction: Continue reading Huh? Cancer paper gets retracted because of its correction

Neuroscientist flags errors in his days-old paper “for the sake of science integrity”

Only days after his paper was published online, a neuroscientist has posted a comment on PubMed alerting readers to several duplication errors.

Despite the issues, which the researcher says were introduced into the final manuscript after peer review, he reassured readers that they do not influence the final conclusions in the paper.

On February 9, ten days after the article came online, corresponding author Garret Stuber at the University of North Carolina at Chapel Hill wrote a detailed comment on PubMed Commons, explaining that the “research community” had brought four figure-related errors to his attention. After investigating the concerns, Stuber discovered that the problems emerged after the peer-review process, “while revising the manuscript to comply with Nature Neuroscience’s final formatting guidelines.” In his note, he outlined the specific duplication issues that arose, which he says he plans to detail to the journal in a formal corrigendum letter.

Stuber alerted the scientific community about his PubMed comment via Twitter: Continue reading Neuroscientist flags errors in his days-old paper “for the sake of science integrity”

Journal retracts paper due to image mismatch; one co-author alleges fraud

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:

Major publisher threatened to sue author who didn’t realize he owed open access fees

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:

Nature paper with massive correction can’t be reproduced, says independent group

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.

Lack of reproducibility triggers retractions of Nature Materials articles

The authors of a highly cited 2015 paper in Nature Materials have retracted it, after being unable to reproduce some of the key findings.

The move prompted the journal to also retract an associated News & Views article.

Here’s the retraction notice for “Fast and long-range triplet exciton diffusion in metal–organic frameworks for photon upconversion at ultralow excitation power:” Continue reading Lack of reproducibility triggers retractions of Nature Materials articles

Karolinska requests retraction of 2014 Macchiarini paper

Paolo Macchiarini

It has been a tough couple of years for surgeon Paolo Macchiarini, once lauded for pioneering a groundbreaking procedure to transplant tracheas.

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.

Here’s more from a release from the institution: Continue reading Karolinska requests retraction of 2014 Macchiarini paper

Controversial gene-editing study flagged by Nature journal

nature-biotechnologyNature Biotechnology has issued an editorial expression of concern (EOC) for a widely criticized study describing a potentially invaluable new lab tool.

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.

Here’s the EOC, published yesterday: Continue reading Controversial gene-editing study flagged by Nature journal

Nature Cell Biology retracts hotly debated cancer paper

ncbLast 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.

Here’s Nature Cell Biology‘s official statement about the paper, in the form of a retraction notice that appears to be written by the authors:  Continue reading Nature Cell Biology retracts hotly debated cancer paper
