Research misconduct finding — which university won’t discuss — leads to second retraction for prominent physicist

A rising star in nanotechnology, Dmitri Lapotko, has received his second retraction within a month over “a finding of research misconduct” that the university will apparently only disclose on a need-to-know basis.

According to the notice, the journal’s editor and publisher issued the retraction after Lapotko’s former institution—Rice University in Houston—notified them of research misconduct and cited figure duplication issues, which meant the results “should not be relied upon and may be scientifically unsound.”

We recently covered the Belarusian physicist’s first retraction in the journal Theranostics, in which an official at Rice would not confirm a misconduct inquiry, telling us that, “Rice University’s investigations of research misconduct are confidential.”

This time, however, the retraction notice explicitly states that a Rice University research integrity officer reported research misconduct to the journal Applied Physics Letters (APL). We contacted the official, B.J. Almond, who still stuck to the original script: Continue reading Research misconduct finding — which university won’t discuss — leads to second retraction for prominent physicist

Author duplicated a figure in three papers; two get retracted

Two journals have retracted two papers by the same group within months of each other, after editors were independently tipped off that they contained duplicated figures representing different experiments.

The two papers were published by PLOS ONE and The Egyptian Journal of Biochemistry and Molecular Biology (EJBMB) in 2015 and 2014, respectively. According to the PLOS ONE paper’s corresponding author, last author Saad A. Noeman from Tanta University in Egypt used the same Figure 1 in both papers, along with another 2013 paper in EJBMB.

Corresponding author Yasser S. El-Sayed, head of the Department of Forensic Medicine and Toxicology at Damanhour University in Egypt, told us he learned of this issue after a reader brought the figure manipulation and duplication concerns to PLOS ONE’s attention.

El-Sayed said that he tried to figure out what had happened.

“Strange. Very strange:” Retracted nutrition study reappears in new journal

In an unusual turn of events, a nutrition paper has come back to life a year after being pulled from its original publication.

After the paper was retracted from the journal Obesity, the authors revised it and republished it in another journal, Pediatric Obesity. Both journals are published by Wiley. The second version of the paper doesn’t mention the previous retraction. Indeed, the journal editor told us he didn’t know the paper had been retracted. Still, he stood by his decision to publish it.

The authors told us the paper was retracted after editors at Obesity raised concerns over the authors’ methodology. The authors revised the paper, adding some analysis and explanation of their methodological approach, and said the new version was accepted by peer reviewers before being published in Pediatric Obesity.

However, an outside expert who reviewed both papers for us said he thinks the authors didn’t change enough. According to Patrick McKnight, head of the Measurement, Research methodology, Evaluation, and Statistics group at George Mason University and a Statistical Advisory Board member of STATS.org:

Authors who retract for honest error say they aren’t penalized as a result

Daniele Fanelli

Are there two types of retractions? One that results from a form of misconduct, such as plagiarism or manipulating figures, and another that results from “honest errors,” or genuine mistakes the authors have owned up to? More and more research is suggesting that the community views each type very differently, and don’t shun researchers who make mistakes and try to correct the record. In yet another piece of evidence, Daniele Fanelli and his colleagues recently published the results of their interviews with 14 scientists who retracted papers for honest errors between 2010-2015. Although much of what scientists said affirmed what Fanelli – based at METRICS (the Meta-Research Innovation Center) at Stanford University – has long argued about retractions due to honest error, some of their answers surprised him.

Retraction Watch: We’ve seen the community reward scientists who retract papers for honest error, including a 2013 paper that showed no citation penalty for researchers who self-retract. Yet the interviewees said they were surprised to realize there weren’t any negative consequences to their self-retractions (some even got kudos for doing it). Why do you think people don’t realize how the community will view honest error?

“It’s been three tough years:” Macchiarini whistleblower cleared of previous charges

Karl-Henrik Grinnemo

Karl-Henrik Grinnemo was worried. The doctor and clinical researcher at the Karolinska Institute was working with a high-profile surgeon who was performing a potentially life-saving procedure on patients, but Grinnemo saw that the patients weren’t doing very well. So in 2013, Grinnemo and three other doctors raised concerns about the work of Paolo Macchiarini. The surgeon initially fought back, and accused Grinnemo of misconduct. KI sided with the star surgeon, and found Grinnemo guilty of “carelessness” in a grant application to the Swedish Research Council, including plagiarism. Readers should by now know how the story ends – Macchiarini’s work has since been largely discredited. Recently, to clear his name, Grinnemo asked authorities to take a second look at his case – and he has been exonerated. We talked to him about the last few tumultuous years.

Ousted editor speaks: I did not manipulate citations

Artemi Cerdà

Last month, a publisher announced that one of its editors had resigned, following accusations he’d asked authors to cite particular papers, boosting his profile and that of journals where he worked. The publisher declined to name the editor. But when an anonymous report began circulating about the incident, the publisher named the researcher: Artemi Cerdà, based at the Universitat de València.

Cerdà has since resigned from other journals, but hadn’t made any public statements that we could find about the incident — until now.

We spoke with Cerdà, who asserted repeatedly that he had not forced authors to add citations to their papers, and was being unfairly accused by journals who had to explain why their impact factors had risen dramatically:

Plant scientist logs 4 more notices over figure errors

Researchers in China have retracted a paper and corrected three others in a plant journal, citing problems with multiple figures.

Lixin Zhang, from the Chinese Academy of Sciences in Beijing, is corresponding author on all four papers, published by Plant Physiology. We’ve reported on three retractions and two corrections from Lixin Zhang and some of the same co-authors, bringing Zhang’s total to five retractions and four corrections, by our count.

According to the retraction notice, the authors agreed to pull the article because of figure-related “irregularities and inappropriate data handling” — but despite these issues, they remain confident that their conclusions are still valid.

Here’s the latest retraction notice, issued this February, for “Cooperation of LPA3 and LPA2 Is Essential for Photosystem II Assembly in Arabidopsis:”  Continue reading Plant scientist logs 4 more notices over figure errors

Patient misdiagnosed with rare neurological side effect in retracted case study

When two surgeons in Greece learned that a patient had developed a rare side effect following weight loss surgery, they were eager to publish the case.

After extensive testing, the patient was diagnosed with Wernicke’s encephalopathy—a neurological disorder caused by thiamine deficiency—following a sleeve gastrectomy procedure. As the authors note in the paper, they had seen only eight other cases following the procedure in the literature.

It turns out, theirs was not the ninth. After the patient unfortunately died, he was examined by a coroner, who ruled he did not, in fact, have Wernicke’s encephalopathy. So Dimitrios Manatakis and Nikolaos Georgopoulos, both based at Athens Naval and Veterans Hospital in Greece, have retracted their 2014 case study.

When the first learned of the patient, the authors wanted to alert the surgical community to the case, given the rarity of this side effect, Manatakis told us: Continue reading Patient misdiagnosed with rare neurological side effect in retracted case study

The latest sting: Will predatory journals hire “Dr. Fraud”?

Katarzyna Pisanski

From time to time, academics will devise a “sting” operation, designed to expose journals’ weaknesses. We’ve seen scientists submit a duplicated paper, a deeply flawed weight loss paper designed to generate splashy headlines (it worked), and an entirely fake paper – where even the author calls it a “pile of dung.” So it wasn’t a huge surprise when Katarzyna Pisanski at the University of Sussex and her colleagues found that so-called “predatory” journals – which are allegedly willing to publish subpar papers as long as the authors pay fees – often accepted a fake editor to join their team. In a new Nature Comment, Pisanski and her team (Piotr Sorokowski, Emek Kulczycki and Agnieszka Sorokowska) describe creating a profile of a fake scientist named Anna O. Szust (Oszust means “a fraud” in Polish). Despite the fact that Szust never published a single scholarly article and had no experience as a reviewer or editor, approximately one-third of predatory journals accepted Szust’s application as an editor. We spoke with Pisanski about the project.

President of Taiwan university to step down amidst investigation

Pan-Chyr Yang

The president of a top university in Taiwan has announced he will resign from his post at the end of his first term in June.

President Pan-chyr Yang of National Taiwan University (NTU) has opted not to seek a second term as president given two recent investigations — one which concluded last month and one which is ongoing — into allegations of misconduct in papers he co-authored.

Despite being cleared of misconduct in the investigation conducted by his university, Yang felt that the scandal had left a stain on NTU’s reputation, which he hoped to restore by stepping down as president. Here’s more from Focus Taiwan: Continue reading President of Taiwan university to step down amidst investigation
