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:

Authors suspended as duplications sink papers on ship building

Computational Materials Science

A pair of researchers affiliated with the University of Galati in Romania were suspended after duplicating work in their papers on materials used to build ships, earning them four retractions last year, and one the year before.

According to Romanian newspaper Impact Est, in December an ethics committee found that co-authors Ionel Chirica and Elena-Felicia Beznea committed “a number of breaches of ethics,” including self-plagiarism. Both received two-year suspensions from holding certain research positions.

These aren’t the only problems Chirica has faced: In 2013, he resigned from his position as the director of the Doctoral School of Engineering, according to Impact Est, for reasons that are unclear. In 2012, he also lost two additional papers on which he is the sole author.

Last fall, Computational Materials Science retracted four papers by Chirica and Beznea, publishing almost identical notices. We’ll start with the one for “Response of ship hull laminated plates to close proximity blast loads:”

Data manipulation flushes paper on gut bacteria

cell reportsData manipulation in a Cell Reports paper blew the importance of a kind of bacteria out of proportion.

Retracted this month — less than three months after it was published — the paper showed, according to a summary on the cover page:

B. subtilis is a symbiont that resides in the gut of C. elegans and generates nitric oxide that is essential for the host. Xiao et al. demonstrate that nitric oxide promotes defense against pathogenic bacteria by activating p38 MAPK, demonstrating the importance of commensal bacteria in host immunity.

But B. subtilis — a member of the Bacillaceae family — aren’t actually as plentiful as they appeared, explains the retraction notice for “Gut-Colonizing Bacteria Promote C. elegans Innate Immunity by Producing Nitric Oxide:”

Biologists earn 5th retraction following Swedish investigation

plos pathA team of biologists have earned a fifth retraction for a paper containing manipulated images, following an investigation by the Swedish government.

Last year, the investigation found that former Uppsala University doctoral student Apiruck Watthanasurorot had manipulated figures in five papers, four of which have already been retracted. Earlier this year, we reported that his supervisor, last author Kenneth Söderhäll, had requested PLOS Pathogens simply correct the fifth paper because independent groups have confirmed the findings. But according to the retraction notice for “Bacteria-Induced Dscam Isoforms of the Crustacean, Pacifastacus leniusculus,” Söderhäll has since agreed to the retraction:

Team in Japan earns third retraction for misconduct

JSRA team of researchers has earned its third retraction after an investigation at Oita University in Japan found instances of misconduct in their research.

The most recent notice mentions the investigation, and specifies that the first author, Satoshi Hagiwara, was responsible for the problematic figures in the paper. Hagiwara is also the first author on two retracted papers we reported on last year; one of the earlier retractions also mentions the investigation, but does not assign responsibility to any particular author. All three papers share three authors.

The retraction notice for “Continuous Hemodiafiltration Therapy Ameliorates LPS-Induced Systemic Inflammation in a Rat Model,” published in the Journal of Surgical Research, explains the issues with the paper:

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

Poll: Should there be a statute of limitation on retractions?

With PubPeer and other online resources (such as PubMed Commons and our comment section), it’s never been easier for readers to raise public suspicions of published papers. But what should we do when we learn about potential problems in papers that are decades old, and all of the authors are deceased?

That’s the question we’re asking ourselves, after reading “Due process in the Twitter age,” this week’s editorial from Science editor Marcia McNutt.

She presents this compelling scenario:

Raw files help fix 2003 figure by heart researcher accused of fraud

7.cover

A researcher accused of misconduct by an anonymous Japanese blogger has corrected a 2003 paper in Circulation Research, after providing a university investigation with the original source files.

Allegations of fraud have dogged Shokei Kim-Mitsuyama for years, and even caused him to step down from his position as editor in chief at another journal. However, Kim-Mitsuyama and his colleagues call the latest correction a “mistake,” which didn’t affect any of the paper’s conclusions.

We’ve unearthed a total of five publications co-authored by Kim-Mitsuyama that have earned corrections, the latest of which cites an investigation by the university:

Singapore investigation leads to another retraction, correction for Harvard research fellow

After an investigation found evidence of misconduct, a biologist has issued a third retraction.

Sudarsanareddy Lokireddy — now a research fellow at Harvard Medical School — “admitted falsification,” a Research Integrity Officer at Nanyang Technological University in Singapore told us in December. According to The Scientist, another journal has also published a correction that the authors had requested earlier.

The newly retracted paper is “Myostatin is a novel tumoral factor that induces cancer cachexia,” published in Biochemical Journal and cited 40 times, according to Thomson Reuters Web of Science. Here’s the retraction note:

Communications researcher loses two book chapters, investigated for plagiarism

BrillA researcher who studies how others communicate is struggling with his own communications: Peter J. Schulz has lost two book chapters for misappropriating the work of others, and is under investigation by his university.

Although the publisher believes the errors were unintentional, the retractions have prompted it to stop selling the books altogether.

Schulz now has a total of three retractions and one erratum for failing to properly cite other works. The University of Lugano in Switzerland, where he is based, told us they’re investigating allegations of plagiarism against him.

Both of the chapters that were recently retracted appear in books published by Brill. The retraction notes say the same thing:
