A cancer researcher who went to court — unsuccessfully — claiming that commenters on PubPeer had cost him a new job has just lost another 12 papers.
The twelve now-retracted papers by Fazlul Sarkar and colleagues — as well as another by Sarkar that is now subject to an editor’s note — all appeared in Cancer Research, which made for a long table of contents in its September 15 issue.

Tokyo Women’s Medical University has stripped a researcher of her PhD, following the retraction of a paper — for data duplication — that was based on her thesis.
The August 30th announcement notes that a degree was revoked on July 20. The announcement does not name the researcher, but refers to degree number 2881, which corresponds to Rika Nakayama’s PhD. The university describes carelessness and errors, but not misconduct.
Here’s a rough Google translation of the announcement: Continue reading Japanese university revokes PhD following a retraction
Journals have retracted all but 19 of the 313 tainted papers linked to three of the most notorious fraudsters in science, with only stragglers left in the literature. But editors and publishers have been less diligent when it comes to delivering optimal retraction notices for the affected articles.
That’s the verdict of a new analysis in the journal Anaesthesia, which found that 15% of retraction notices for the affected papers fail fully to meet standards from the Committee for Publication Ethics (COPE). Many lacked appropriate language and requisite watermarks stating that the articles had been removed, and some have vanished from the literature.
The article was written by U. M. McHugh, of University Hospital in Galway, Ireland, and Steven Yentis, a consultant anaesthetist at Chelsea & Westminster Hospital in London. Yentis was editor of Anaesthesia during the three scandals and had a first-hand view of two of the investigations. He also is the editor who unleashed anesthetist and self-trained statistician John Carlisle on the Fujii papers to see how likely the Japanese researcher’s data were to be valid (answer: not very likely). Continue reading When it comes to retracting papers by the world’s most prolific scientific fraudsters, journals have room for improvement
Five journals published by a prominent cancer research society have retracted a total of 10 papers — most of them by a former researcher at the MD Anderson Cancer Center in Houston.
Nine of the 10 retractions share that researcher, Bharat Aggarwal, as an author. Aggarwal — who more than five years ago threatened to sue us for reporting on an investigation into his work — is now up to 28 retractions, and has left his post at MD Anderson. The AACR is also appending an editor’s note to eight of his other papers — but it has not explained the reason for what it acknowledges is a lag in moving on these articles.
“Unfortunately, we have been delayed in correcting the published record, and for this we apologize,” writes the publisher of The American Association for Cancer Research (AACR), Christine Rullo, in a note in this month’s issue of Cancer Research. Rullo doesn’t say how long the journals took to handle the retractions. Continue reading Cancer journals retract 10 papers, flag 8 more, and apologize for the delay
If you read this space, you probably know the name Brad Bushman. He studies the effects of violent video games on the people who play them. He also has just retracted his third paper, and significantly corrected another.
Although Bushman remains a prominent voice in a highly contentious field — prompting numerous media to consult him after school shootings or other violent acts — he’s retracted two papers, one following an investigation at his institution, the Ohio State University (OSU), which prompted OSU to strip his co-author of her PhD. (There’s a lot more to tell about that story, including the backlash outside critics faced for taking their concerns about the paper public. To read more, check out our in-depth piece in Motherboard.)
Bushman’s third retraction came this month; he nearly had a fourth as well, but attorneys for the publisher decided that a massive correction (to a paper which previously had been flagged with an expression of concern) would be more appropriate.
The retraction notice from Current Opinion in Psychology states the paper showed too much similarity to a 2016 paper in the same journal by Bushman and Arlin James Benjamin, based at the University of Arkansas-Fort Smith. It notes that although Bushman was the guest editor of the issue of the journal:

The similarities between recent papers in two different journals about energy were striking — so striking that a number of people have taken to Twitter and Facebook to let the world know about them.
[1415 UTC, August 29, 2018: See update at the end of this post.]
One paper, “Systematic investigation of the impact of operation conditions on the degradation behaviour of perovskite solar cells,” was authored by a group of researchers in Lausanne, Switzerland and appeared on January 1, 2018 in Nature Energy. Its abstract reads: Continue reading UPDATED: Elsevier retracts a paper on solar cells that appears to plagiarize a Nature journal. But the reason is…odd.
Ulrich Lichtenthaler, a management professor who has had to retract 16 papers for data irregularities, has a new position in academia.
According to a news release from the International School of Management (ISM), a business school based in Germany, Lichtenthaler has been appointed Professor of Business Management and Entrepreneurship at the Cologne campus. Lichtenthaler is also taking over as one of the directors of the Entrepreneurship Institute at ISM, which conducts research in the field.
Lichtenthaler’s name may be familiar to readers: After journals retracted more than a dozen of his articles, he resigned from a previous post at the University of Mannheim in 2015.
We emailed Lichtenthaler to ask if he had disclosed his history to his new employers; he forwarded the email to ISM’s head of marketing and sales, who told us:

Sometimes, corrections are so extensive, they can only be called one thing: Mega-corrections.
Recently, the Proceedings of the National Academy of Sciences (PNAS) issued a four-page correction notice to a paper about a compound that appeared to reduce the chances a cancer will recur. The notice describes figure duplication, problems with error bars and figure legends — as well as the loss of statistical significance for some data.
According to the authors’ statement in the notice:

The authors of a 2018 paper on how noisy distractions disrupt memory are retracting the article after finding a flaw in their study.
The paper, “Unexpected events disrupt visuomotor working memory and increase guessing,” appeared in Psychonomic Bulletin & Review, a publication of the Psychonomic Society. (For those keeping score at home, psychonomics is the study of the laws of the mind.)
The article purported to show that an unexpected “auditory event,” like the sudden blare of a car horn, reduced the ability of people to remember visuomotor cues. Per the abstract:

When Nature published a paper in 2011 describing a compound extracted from a pepper plant that appeared to kill cancer cells but leave healthy cells unscathed, it got some attention.
Of course, the news caught the media’s eye, but also that of other researchers, who have since jumped on the concept, and continued to study the effects of the compound — piperlongumine — on cancer, as well as other conditions.
But ever since the 2011 letter appeared, researchers have raised concerns about some of the figures — including one that showed mice with massive tumors, suggesting they had experienced an unreasonable amount of distress during the study. Nature has responded by issuing two lengthy correction notices in 2012 and 2015 — as well as an editorial that admitted the animals may have “experienced more pain and suffering than originally allowed for,” but did not warrant retracting, as the results remained “valid and useful.”
Today, the journal is retracting the paper, with the following brief notice:
