Nature paper adds non-reproducibility to its list of woes

with one comment

Despite taking some serious hits, a 2006 letter in Nature isn’t going anywhere.

Years ago, a university committee determined that two figures in the letter had been falsified. The journal chose to correct the paper, rather than retract it — and then, the next year, published a correction of that correction due to “an error in the production process.” To round it out, in June of last year, Nature published a rebuttal from a separate research group, who had failed to replicate the letter’s results.

Still, the first author told us there are no plans to retract the paper, since the follow up experiments published in the corrections confirmed the paper’s conclusions.

Two more retractions for stem cell researcher appealing her dismissal

with 4 comments

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: Read the rest of this entry »

Huh? Cancer paper gets retracted because of its correction

with 2 comments

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: Read the rest of this entry »

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

with one comment

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: Read the rest of this entry »

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

with 16 comments

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

with 11 comments

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

with one comment

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

with one comment

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:” Read the rest of this entry »

Karolinska requests retraction of 2014 Macchiarini paper

without comments

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: Read the rest of this entry »

Controversial gene-editing study flagged by Nature journal

with 2 comments

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: Read the rest of this entry »
