Journals retract paper, flag two others by cancer doc under investigation

Carlo Croce

This weekend, Carlo Croce had some reprieve from the misconduct accusations that have followed him for years (recently described in a lengthy article in the New York Times) and that have prompted his university to re-open an investigation. On Sunday, he received a prestigious award from the American Association for Cancer Research, honoring his work.

But the moment may have been short-lived. Today, Croce received two expressions of concern (EOCs) from PNAS for two well-cited papers published over a decade ago, on which Croce — chair of the Department of Cancer Biology and Genetics at The Ohio State University (OSU) — is last author. The two EOCs cite concerns over duplicated bands. What’s more, another journal recently decided to retract one of his papers, citing figures that didn’t represent the results of the experiments.

PNAS chose to issue EOCs, rather than retractions or corrections, because the authors didn’t agree that the bands were duplicated, according to executive editor Diane Sullenberger. She explained how the journal learned of the issues with the two papers: Continue reading Journals retract paper, flag two others by cancer doc under investigation

Five retractions for engineering duo in South Korea over duplication, fraudulent data

An engineering student in South Korea and a professor have retracted five papers from four different journals for reasons ranging from figure duplication to manipulated or fraudulent data.

Jae Hyo Park, who is pursuing his PhD, and Seung Ki Joo, a professor in the department of material science and engineering at Seoul National University in South Korea, appear on all five papers as first and last author, respectively.

According to an official at IOP Publishing, the retractions began when a third party contacted them last March about “potential misconduct” in a paper published earlier that year in one of its journals—Journal of Physics D: Applied Physics. The IOP official Simon Davies explained: Continue reading Five retractions for engineering duo in South Korea over duplication, fraudulent data

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.

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

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

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

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:

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.
