Journal retracts two papers by authors who lifted others’ data

A journal has retracted two 2014 papers after the editors discovered the authors used data from other research groups without permission.

The papers, both published in the same issue of Cell Biochemistry and Biophysics and retracted in May, suffered from similar issues—the authors published data that was not theirs. The authors are all based at different institutions in China; as far as we can tell, the papers do not have any authors in common.

When we asked the publisher whether a third party, such as a paper mill, may have been involved, a spokesperson for Springer told us: Continue reading Journal retracts two papers by authors who lifted others’ data

No new math: Journal pulls math paper with “already known” results

A mathematics journal has withdrawn a paper after discovering that the results were not new.

The paper, published online in March in Communications in Algebra, explored the properties of group rings, a discipline of algebra. According to editor-in-chief of the journal, Jason Bell, author Francis E. A. Johnson, a professor of mathematics at the University College London, devised a property associated with group rings, and defined it using the term “weakly finite.” But, at the time, Johnson was not aware that other experts had already defined the same property, using the term “stably finite.”

Bell, a professor of mathematics at the University of Waterloo in Ontario, and Lance Small, the journal’s other editor-in-chief, stressed that this issue was “definitely not a matter of plagiarism.” Bell and Small told us in a joint statement that “it was ultimately no one’s fault—it is just one of these things that can happen occasionally in mathematics research.” But given the overlap, the editors thought it best to withdraw the paper, they said: Continue reading No new math: Journal pulls math paper with “already known” results

12 years after researcher found guilty of misconduct, journal retracts paper

In 2005, the U.S. Office of Research Integrity found an obesity researcher had engaged in scientific misconduct.

More specifically, the ORI report revealed that Eric Poehlman, then based at the University of Vermont, had “falsified and fabricated” data in 10 papers. The 2005 report asked that the journals issue retractions or corrections to the papers. By 2006, six of those papers were retracted (1, 2, 3, 4, 5, 6). In 2006, a judge sentenced Poehlman to one year and one day in prison for falsifying research data.

In 2015, we explored how long it takes a journal to retract a paper. We found that four of the 10 papers had still not been retracted — one appeared to be missing from Medline, another had received a correction (as the ORI report requested), and two had not been retracted or corrected (1, 2).

Until now. Continue reading 12 years after researcher found guilty of misconduct, journal retracts paper

Journal alerts readers to “technical criticism” of CRISPR study

A Nature journal has posted a editor’s note to a recent letter on potential unintended consequences of CRISPR gene editing, after an executive at a company trying to commercialize the technology said the paper should be retracted.

The original article, published on May 30 as a correspondence in Nature Methods, suggested that using CRISPR in mice can lead to unexpected mutations. But last week, the journal added an “Editorial note” online. Nature Methods says the notice is not an expression of concern, which would be a stronger suggestion that the paper is problematic; it simply wants to alert readers to the fact that, as the note states:

Big corrections usually weaken findings. But a recent NEJM one strengthened them, author says

A 2016 study in New England Journal of Medicine has received a substantial correction, which affected several aspects of the article.

Typically, an error that affects so much of a paper would undermine the results (and possibly lead to a retraction). But in this case, the revised dose calculations actually strengthened the findings, according to the first author.

The NEJM study aimed to clarify whether patients with a neuromuscular disease called myasthenia gravis benefit from a surgical procedure to remove the thymus. About half of the patients received surgery plus the steroid prednisone, while the rest only received the steroid. The researchers found patients who received the surgery fared better.

Shortly after the paper was published in August 2016, the authors discovered an error in the calculation of the average prednisone dose. According to Gil Wolfe, the first author of the paper, when the researchers corrected the error: Continue reading Big corrections usually weaken findings. But a recent NEJM one strengthened them, author says

NIH researcher doctored 11 figures in 2016 paper, says ORI

A former Research Training Awardee at the National Institutes of Health “falsified and/or fabricated data” in 11 figures in a 2016 paper, according to the U.S. Office of Research Integrity.

This is the first finding of misconduct issued this year by the ORI.

According to the finding, published in the Federal Register, Brandi M. Baughman — formerly at the National Institute of Environmental and Health Sciences (NIEHS) — tweaked data and text in a PLOS ONE paper about screening for compounds that inhibit an enzyme known as inositol phosphate kinase. According to the notice, however, some of those experiments didn’t proceed as described:

Former prof fudged dozens of images, says university

On Dec. 2, 2013, Alison Lakin, the research integrity officer at the University of Colorado Denver, received a concerning email.

The emailer was alleging several problems in a 2012 paper in the Journal of Clinical Investigation, co-authored by one of its high-profile faculty members. Lakin discussed the allegations with some administrators and agreed they had merit; Lakin sequestered an author’s laptop and other materials. Over the next few months, the university learned of additional allegations affecting other papers — and discovered even more serious problems in the JCI paper. Namely, the first author had inserted changes to 21 figures in the paper after submitting it, without alerting the other authors, journal, or reviewers.

That journal retracted the paper this month, citing numerous problems:

Journal hit by citation scandal named among top in field

It’s been a mixed year for Wiley’s Land Degradation & Development.

Following accusations of citation irregularities at the journal (whose its Impact Factor rose dramatically from 3.089 in 2014 to 8.145 in 2015), its editor was asked to resign. Another editor resigned shortly after.

But last week, Clarivate Analytics named the journal among the top 10 in the field of climate change, as part of its annual Journal Citation Reports.

The annual report also lists a number of journals that have been suppressed from Clarivate’s analysis “due to anomalous citation patterns;” Land Degradation & Development is not listed among the 13 journals this year.

A spokesperson for Clarivate told us:

Journal flags cancer paper from Karolinska researchers

A journal has issued an expression of concern (EOC) for a 2011 cancer paper, while Karolinska Institutet investigates “concerns” about some of the data.

After the Journal of Cell Science (JCS) received a tip from a reader, it investigated, but was unable to resolve the concerns. So the journal asked KI–where all the authors work–to investigate further, and issued an EOC to alert readers that there may be an issue with the paper.

According to the notice, the questions center on data from Fig. 1A, but the notice does not specify the nature of the concerns. The 2011 paper received a correction in 2016, which cites inadvertent figure duplication.

Earlier this year, the paper’s last author Boris Zhivotovsky and second author Helin Vakifahmetoglu-Norberg retracted a 2008 paper from Oncogene over potential image duplication. That retraction caught our attention because it was prompted by a 2016 correction to the paper, which had raised additional questions about potential duplication; ultimately, the authors retracted both the paper and its correction.

Here’s the expression of concern for the 2011 JCS paper: Continue reading Journal flags cancer paper from Karolinska researchers

Meet PubPeer 2.0: New version of post-publication peer review site launches today

Since it launched in 2012, PubPeer has grown to become a standard part of the scientific lexicon, and its numerous post-publication discussions have led to more editorial notices than we can count. But it’s also faced its share of critics, including a scientist who took the site to court to unmask commenters he alleged had cost him a job offer. The site won that case on appeal, but is today launching new features that will make it impossible for the site to reveal users’ identities, as well as easier to read and format comments. We spoke with PubPeer co-founder Brandon Stell about what to expect from the new site.
