“Mixed up” images earn biologists four retractions

525480Four different journals have pulled papers from the same authors due to alleged duplication or manipulation of images.

All four papers have two authors in common — Jianting Miao and Wei Zhang, both based at The Fourth Military Medical University in Xi’an City, Shaanxi, China. Many of the other co-authors are also listed in two or three of the retracted papers.

Miao claims that the photographs got “mixed up” due to the researchers’ “great carelessness” and “insufficient knowledge.” He told us:

Biologist under investigation asks journal to swap image, journal retracts the paper

When a researcher discovered one of the images in her papers was a duplication, she asked the journal to fix it — but the journal decided to retract the paper entirely.

The researcher, Suchitra Sumitran-Holgersson, is currently being investigated by the University of Gothenburg in Sweden after a number of her papers were questioned on PubPeer. She told us the duplication was the result of ‘‘genuine human error.’’ Tissue Engineering Part A, however, decided the request to swap the image was a ‘‘cause for concern,’’ and chose to retract the paper. 

Here’s the retraction notice:

Materials journal breaks three papers from the same author

Metals and Materials Journal.

Metals and Materials International has retracted three papers from one author, due to suspicions of plagiarism and authorship issues.

The three papers have one thing in common — the same lead author, Reza Haghayeghi from the Islamic Azad University in Tehran, Iran.

The retraction notices — all released in March, 2016 — lead with the following:

Seven more retractions for anti-terrorism prof brings count to 15

MemonAnti-terrorism researcher Nasrullah Memon has notched seven more retractions, bringing his total up to 15 — earning him a spot on our leaderboard.

We previously reported on eight pulled papers authored by Memon, based at the University of Southern Denmark in Odense. There was some confusion over whether his count then increased to nine — but, following a retracted retraction, his total was back to eight.

Now, it seems like the retracted retraction has been re-retracted, and six other of Memon’s publications have been pulled. Memon has also been found guilty of plagiarising his PhD thesis, and more of his work is being questioned online.

The retraction notices for the newly pulled material — all published by Springer — include the following statement: Continue reading Seven more retractions for anti-terrorism prof brings count to 15

How much does a retracted result pollute the field?

Research Integrity and Peer Review

When a paper is retracted, how many other papers in the same field — which either cite the finding or cite other papers that do — are affected?

That’s the question examined by a study published in BioMed Central’s new journal, Research Integrity and Peer Review. Using the case of a paper retracted from Nature in 2014, the authors found that subsequent research that cites the retracted paper often repeats the problematic finding, thereby spreading it throughout the field. However, papers that indirectly cited the retracted result — by citing the papers that cited the Nature paper, but not the Nature paper itself — typically don’t repeat the retracted result, which limits its spread.

Here’s how the authors describe their findings in the paper: Continue reading How much does a retracted result pollute the field?

Plant biologist’s paper pulled for falsification, three more questioned on PubPeer

PMBP Cover ImagePhysiology and Molecular Biology of Plants has retracted a paper about using Darjeeling tea clones against abiotic stress for problems with one of the figures.

The specific problem: “falsification/fabrication” of data underlying the figure, which the corresponding author — Sauren Das from the Indian Statistical Institute in Calcutta, West Bengal — couldn’t resolve. Das told us he denies the allegations made by the journal.

Meanwhile, three other papers by Das have been questioned on PubPeer. 

Let’s take a look at the retraction note: Continue reading Plant biologist’s paper pulled for falsification, three more questioned on PubPeer

Confusion reigns: Are these four retractions for compromised peer review, or not?

Open Automation Journal CoverThe Open Automation and Control Systems Journal has published five items this calendar year — and all of those are retraction notices.

That’s what we’re sure about. Now to what we’re not clear on in this story, which is one of a growing number of cases we’ve seen in which so-called “predatory” publishers are starting to retract papers, perhaps because they hope the practice suggests they are rigorous. Four of the papers have been pulled for “compromised” peer review, some of which are due to the actions of an “external agent,” according to the journal. A co-author of one of these manuscripts, however, claims the paper has been pulled for using material from another researcher’s paper without acknowledgement but the journal has retracted it for issues with peer review.

The remaining paper has been pulled for plagiarizing from another published paper.

Let’s take a look at the retraction notice for the four papers felled by rigged peer review, which are all similar. They read: Continue reading Confusion reigns: Are these four retractions for compromised peer review, or not?

Neuroscience journal retracts expression of concern 15 years after investigation

Here’s something we don’t get to write about often: A journal has retracted an expression of concern (EOC) more than 15 years after issuing it.

What took so long? Apparently, the European Journal of Neuroscience (EJN) just recently learned about a review carried out by the author’s previous institution, which concluded that she had not committed misconduct.

Let’s take a look at the retraction note of the expression of concern, which was published last month: Continue reading Neuroscience journal retracts expression of concern 15 years after investigation

Paper linking fecal transplants to obesity in rats retracted for faked data

Diabetes Cover

A paper linking the fecal microbiome to obesity has been retracted after it became clear that one of the co-authors faked some of the data.

The 2014 paper in Diabetes — which found that rats given fecal transplants from obese mice were more likely to become obese themselves if given a particular diet — was pulled after after an institutional investigation found a co-author guilty of falsifying data underlying one figure and fabricating the data of two others.

Co-author Yassine Sakar — formerly based at the French National Institute of Agronomic Research (INRA) in Paris, France — was found responsible for the misconduct. But an official from the institution said that some responsibility must also be shared by the corresponding author Mihai Covosa, who has since resigned from the institution.

Here’s the retraction notice: Continue reading Paper linking fecal transplants to obesity in rats retracted for faked data

Biologist critiques own paper, journal retracts it — against her wishes

Evolution Cover ImageThe journal Evolution has retracted a 2007 paper about the roles of the different sexes in searching for mates, after the same author critiqued the work in a later paper. 

The case raises important questions about when retractions are appropriate, and whether they can have a chilling effect on scientific discourse. Although Hanna Kokko of the University of Zurich, Switzerland — who co-authored both papers — agreed that the academic literature needed to be corrected, she didn’t want to retract the earlier paper; the journal imposed that course of action, said Kokko.
