Nightmare scenario: Text stolen from manuscript during review

A food science journal has retracted a paper over “a breach of reviewer confidentiality,” after editors learned it contained text from an unpublished manuscript — which one of the authors appears to have reviewed for another journal.

The publisher and editors-in-chief of the Journal of Food Process Engineering became aware of the breach when the author of the unpublished manuscript lodged a complaint that his paper, under review at another journal, had been plagiarized by the now retracted paper.

We’re hazy on a few details in this case. Although the journal editor told us the “main author” of the retracted paper reviewed the original manuscript for another journal, the corresponding author of the retracted paper said he was not to blame. (More on that below.)

When looking into the matter, the publisher found that one of the co-authors of the published paper had acted as a reviewer of the unpublished manuscript. Alexandra Cury, an associate editor at Wiley, explained: Continue reading Nightmare scenario: Text stolen from manuscript during review

Macchiarini blames Karolinska for losing data as he retracts 2014 paper

Ask and ye shall receive: A journal has retracted a 2014 paper by Paolo Macchiarini, upon request from the Karolinska Institutet (KI).

The latest news is only one step in a long-running saga about former star surgeon Macchiarini, who was dismissed from KI last year. To read more, check out our timeline.

KI announced it was asking the journal to pull the paper late last year, after concluding that four authors — including Macchiarini — were guilty of scientific misconduct. The paper had already been flagged by the journal with an expression of concern, noting the data presented in the paper may not be “fully representative” of the experiments.

Today, the journal issued a retraction notice, saying the authors wanted to retract the paper. All of the authors who could be reached have agreed to the retraction, including Macchiarini.

Here’s more from the notice:

Scientist who sued university earns two more retractions, bringing total to five

A scientist who sued his employer for millions of dollars has earned two more retractions, for papers that had already been flagged by the journal.

By our count, Rakesh Kumar now has five retractions and multiple corrections.

Kumar sued his employer, George Washington University, for $8 million, alleging emotional distress when they put him on leave from his position as department chair following a finding of misconduct. That suit was settled last year, for undisclosed terms.

The two newest retractions in the Journal of Biological Chemistry — which tagged the papers with Expressions of Concern last year — both state that, according to Kumar, the problematic figures were assembled by “specific co-authors” — unnamed — in his lab. Here’s the first notice:

Physics paper’s results off by factor of 100

Researchers from China have retracted a physics paper after realizing an error led them to report results that were nearly 100 times too large.

What’s more, the authors omitted key findings that would enable others to reproduce their experiments.

According to the notice, the authors used a value to calculate a feature of electrons—called mobility—that “was approximately 100 times too small,” which led to results that were “100 times too large.” The notice also details several gaps in the presentation of experimental results, which preclude others from duplicating the experiments.

Here’s the retraction notice for “Bulk- and layer-heterojunction phototransistors based on poly[2-methoxy-5-(2′-ethylhexyloxy-p-phenylenevinylene)] and PbS quantum dot hybrids:” Continue reading Physics paper’s results off by factor of 100

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

Why don’t the raw data match what was reported in a chemistry paper?

Chemistry researchers in China have retracted their 2016 paper after reporting that the raw data did not match what they presented in the article.

The authors were attempting to develop a method to produce large amounts of a high-quality two-dimensional form of antimonene, a prized crystal structure that has been notoriously difficult to synthesize reliably.

They were successful, according to the paper, achieving “a large quantity of few-layer antimonene” and demonstrating its “exact atomical structure” and properties.

But they may have spoken too soon. Continue reading Why don’t the raw data match what was reported in a chemistry paper?

Prominent NIH researcher up to a dozen retractions

Neuroscientist Stanley Rapoport hasn’t had much luck with his co-authors.

Recently, we’ve reported on multiple retractions of papers co-authored by Rapoport after three different first authors were found to have committed misconduct. Now, the fallout from one of those cases had led to four more retractions, bringing Rapoport’s total to 12.

The latest batch of retractions stem from the actions of Jagadeesh Rao.

Here’s the first notice, issued by Psychopharmacology:

Another correction for prominent cancer researcher who’s dodged accusations for decades

The chair of a biology department who has faced years of misconduct accusations has taken another hit—a lengthy correction due to text “overlap” between one of his PNAS papers and six other articles.

According to the correction, a reader contacted the journal to notify the editors that text and sentences in multiple sections of the 2015 paper — on which Carlo Croce is last author — were lifted from other sources without quotation marks.

This is the second correction for Croce in PNAS regarding overlap issues in just the last few weeks—the first was published on March 7 (see here). In both instances, PNAS did not call the textual similarities plagiarism, but the notice details multiple instances of overlap.

Croce, the chair of the department of cancer biology and genetics at The Ohio State University (OSU), is no stranger to controversy.

Editors retract paper about anesthesia procedure after investigation uncovers data issues

The editors of an anesthesiology journal have retracted a paper about predicting how patients will respond to a procedure, after the results of an investigation cast doubt on the validity and originality of the work.

According to the retraction notice, the editors became concerned about the validity of the data and conducted an investigation, which found irregularities, “including misrepresentation of results.” Because the authors could not provide adequate evidence to assuage these concerns, the editors decided to retract the paper.

The paper — about which facial muscles best predict if a patient is ready to be intubated — had already been flagged on F1000: A few years ago, two anesthesiologists from Florida commented that they found the article “confusing,” and felt that the authors “did not prove their hypothesis.”

Here’s the retraction notice for “Comparison of four facial muscles, orbicularis oculi, corrugator supercilii, masseter or mylohyoid, as best predictor of good conditions for intubation: A randomised blinded trial,” published in the European Journal of Anaesthesiology in 2013 and cited once: Continue reading Editors retract paper about anesthesia procedure after investigation uncovers data issues

Negligence by stressed-out postdoc led to retraction of high-profile paper, supervisor says

The timing was tight, but Sergio Gonzalez had done it. Gonzalez, a postdoctoral researcher at the Institute for Neurosciences of Montpellier (INSERM) in France, had a paper accepted in a top journal by the end of 2015, just in time to apply for a small number of highly sought-after permanent research positions that open up in France each year.

If Gonzalez had missed the January deadline for this system of advancement, known as concours, he would have had to wait until the following cycle to apply.

Once his paper was accepted by the Journal of Clinical Investigation, Gonzalez could breathe a sigh of relief. He began being invited to interviews. But then, a comment showed up at PubPeer.
