Peer review scam leader now up to 20 retractions

We’ve unearthed four more retractions for Khalid Zaman, an economist who lost 16 papers in 2014 for orchestrating fake peer review.

That brings Zaman’s total to 20, and ties him at the #18 spot on our leaderboard.

One of the more recently discovered retractions is for fake peer review, attributed to Zaman; one is for plagiarism, and two other papers were withdrawn while in press, for reasons that are unclear. (Note bene: These retractions are all at least one year old.)

First, the retraction notice for peer review issues, published in April 2015 for “Environmental Indicators and Energy Outcomes: Evidence from World Bank’s Classification Countries:”

Author: I’ll sue if publisher doesn’t retract my retraction

Journal of Homeland Security

An author is preparing to sue a publisher for retracting his paper.

John Bishop, the CEO of an independent media company called Crocels, argues that by taking down his paper, De Gruyter is breaching a contract — their agreement to publish his work.

Perhaps appropriately, the paper suggests ways to combat negative online comments — including litigation.

Bishop told us he learned that his paper was pulled when he was alerted to the brief retraction notice, published in April. The notice, published in the Journal of Homeland Security and Emergency Management, says:

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:

Cancer paper that doctored image from Science story earns retraction

lungcancercoverHere’s a joke for all you middle-schoolers out there. How are doctored images like bad pennies? They keep cropping up!

Here’s the latest one we’ve picked up: Lung Cancer has retracted a 2014 paper on the genetics of tumors after concluding the authors cribbed a figure that had appeared in a 2005 feature story in Science.

The paper, “ß-elemene against human lung cancer via up-regulation of P53 protein expression to promote the release of exosome,” drew attention on PubPeer last September from a reader who noticed striking similarities between one of the images the authors used and a figure in the Science piece (subscription required). According to the PubPeer commenter: Continue reading Cancer paper that doctored image from Science story earns retraction

Stem cell researchers fix two papers following PubPeer comments

Screen Shot 2016-04-13 at 5.56.09 PMA pair of stem cell researchers have earned two corrections, the result of images that were mislabeled, distorted, or compiled incorrectly, according to the notices.

Kang Cheng prepared the gels when he was a research fellow in last author Sanjeev Gupta‘s lab at the Albert Einstein College of Medicine. Gupta told us he reviewed the original gels, and the errors didn’t affect the conclusions in the papers, which were reproducible. He noted he believes the problems are the result of honest mistakes:

The errors did not confer any benefits whatsoever either for the papers or for Dr. Cheng.

On PubPeer, commenters have raised questions about the now corrected papers — along with several others on which Gupta is the senior author, but Cheng is not a co-author.

Edward Burns, research integrity officer at Einstein, told us that the medical school looked into an allegation of misconduct against Gupta:

Imposter edits journal in latest peer review scam

Screen Shot 2016-04-22 at 5.49.05 PMWhen a computer scientist approached a journal about editing a special issue, little did the journal know he — or she — was using a stolen identity.

Before the jig was up, someone posing as a researcher named Xavier Delorme had edited three articles on optimization problems for The Scientific World Journal. The scammer used a fake email address, the publisher told Retraction Watch — a common strategy for duping journals in peer review scams. When the real Delorme, who works at École Nationale Supérieure des Mines de Saint-Etienne in France, began receiving correspondence about articles he had no involvement in, fake Delorme’s cover was blown.

Upon closer look, the publisher found evidence that peer reviews for some articles may have been submitted using phony identities, as well. The publisher has been unable to identify anyone responsible for the scam.

Here’s the retraction notice, which now appears on five articles from the special issue:

Physics journal pulls two papers for data shortcuts

New Journal of PhysicsA publisher is retracting two papers today by a team of physicists who took a short cut in reporting their data.

The papers present a method for imaging very small things — like biological processes on a molecular scale — that could be an alternative to electron microscopy, as the authors explain in a video. But after the papers were published in the New Journal of Physics, last author Ulf Leonhardt, now based at the Weizmann Institute of Science, found out that some of the data

 were pixel-by-pixel mirror-symmetric, which is impossible for genuine experimental data.

One of the researchers co-authored a subsequent paper that acknowledges one of the papers incorrectly assumed the data were symmetrical, and could therefore be extrapolated from one side to the other. A representative of the publisher told us they have not seen any signs of misconduct, and the problem seemed to result from a “series of apparent miscommunications between the authors.”

Here’s the retraction notice for “Evidence for subwavelength imaging with positive refraction:” Continue reading Physics journal pulls two papers for data shortcuts

Journal flags duplicated text by gynecologic cancer researcher with 13 retractions

cancers-logo

When journals discover duplicated material, many choose to retract — but a cancer journal recently faced with the same dilemma involving a researcher with multiple retractions under his belt has instead decided to flag the paper with an expression of concern.

An editor told us that Cancers considered retracting the paper, by gynecologic cancer researcher Noriyuki Takai, but decided not to because the paper

contains some novel content that is of interest to the scientific community.

“Epigenetic Therapy in Human Choriocarcinoma,” published in 2010, has been cited once, according to Thomson Reuters Web of Science, and self-plagiarizes from other publications by Takai and his co-author, Hisashi Narahara. Both are researchers at Oita University in Japan.

Here’s the expression of concern:

Book publisher: Authors plagiarized “in good faith” because they cited previous work

A publisher has retracted a chapter from a book on flow cytometry after determining the authors plagiarized some material — but noted that because the authors cited the article they lifted from, they likely acted “in good faith.”

We were tipped off to this retraction from the authors of the review article the chapter plagiarized from, who told us they were upset by the incident and doubted whether the authors had performed the experiments they described in the chapter.

More broadly, the retraction raises an important question: How can publishers retract one chapter of a book, leaving the rest intact?

First, let’s take a look at the retraction notice: Continue reading Book publisher: Authors plagiarized “in good faith” because they cited previous work
