“Knowledgeable informant” outs researchers for falsifying data

A pathology journal has retracted a 2015 paper from researchers in China after concluding the authors had falsified and copied some of the data and text.

According to the notice, a “knowledgeable informant” told the journal about the overlap and “fraudulent” aspects of the paper, which the editors were able to confirm. The journal retracted the paper last month.

Here’s the retraction notice for “Genistein attenuates glucocorticoid-induced bone deleterious effects through regulation Eph/ephrin expression in aged mice:”

Journal flags another paper by diabetes researcher who sued to stop retractions

It would seem that resorting to legal means to avoid editorial notices doesn’t always work.

We’re coming to that conclusion after seeing yet another notice for Mario Saad, based at the University of Campinas in São Paulo, Brazil. In this case, it’s an expression of concern from the Journal of Endocrinology, on a 2005 paper that lists Saad as the second-to-last author. According to the notice, the journal is concerned the paper contains spliced and duplicated images; although the authors offered to repeat the experiments, the journal considered that potential delay “unacceptable.”

Despite Saad’s legal efforts, he is now up to 11 retractions, along with multiple expressions of concern.

Here’s the full text of the notice (which is paywalled, tsk tsk):

Prominent physicist loses paper over data falsification

A paper by a promising nanotechnologist has been retracted for data falsification.

Dmitri Lapotko, a Belarusian researcher with a background in laser weaponry, made a name for himself at Rice University in Houston, where he studied the use of nanotechnology to diagnose and treat human diseases. That work earned him significant press coverage, including stories in the New York Times and Science.

But that nanobubble may be bursting. The journal Theranostics has retracted a 2011 paper on which Lapotko is the last and corresponding author, citing questions over data falsification. What’s more, another journal has warned readers there may be a problem with a figure in a 2012 paper on which Lapotko is listed as last author.

Lapotko has since left Rice for Masimo Corp., a developer of monitoring devices for patients in the operating room.

According to the Theranostics notice:

Cancer researcher has dodged accusations for decades (and has a new correction)

Today isn’t a great day for Carlo Croce, chair of the department of cancer biology and genetics at The Ohio State University (OSU).

The New York Times has a lengthy article detailing the misconduct accusations that have swirled around Croce for years. We’ve covered many, but The Gray Lady obtained documents that show there have been many more.

The story mentions a 2013 letter from Ohio State University to pseudonymous whistleblower Clare Francis (which we reported on in 2014), acknowledging Francis’s allegations against Croce. However, in the letter, an administrator said OSU saw no reason to investigate Croce.

The story didn’t stop there, as the Times reports:

Something new: A journal publishes running tally of retractions

Here’s something we haven’t seen before: A journal based in Serbia recently began listing all the articles it has retracted, all due to plagiarism.

Although preventing plagiarism is hardly a new goal for journals, creating a web page dedicated to retractions is certainly a novel attempt. (Even the home page has a link to the page, called “Retracted Articles.”)

This past February, the Journal of Process Management – New Technologies International did exactly that. Currently, this page on the journal’s website features five papers, all retracted in 2016, along with links to notices which indicate the original, plagiarized article.

First, let’s list the notice for “Impact of shopper’s creativeness on shopping methods: A case-study of students of University of Delhi (India),” published in 2014:

“Hindsight’s a bitch:” Colleagues dissect painful retraction

Two blog posts are shining additional light on a recent retraction that included some unanswered questions — namely, the identity of the researcher who admitted to manipulating the results.

To recap: Psychological Science recently announced it was retracting a paper about the relationship between the words you use and your mood after a graduate student tampered with the results. But the sole author — William Hart, an assistant professor at the University of Alabama — was not responsible.

The post raised some questions — for instance, who was the graduate student, and if his or her work was so influential to a paper, why was he/she not listed as an author? Hart declined to identify the student, but two new blogs — including one by one of Hart’s collaborators at the University of Alabama — are providing more details.

Author says he lied about approval for animal research

A researcher in South Korea has retracted a 2015 paper after telling the journal he falsified the institutional approval required to conduct the animal experiments.

In the article, the author explicitly says that the Animal Experiment Review Board of a university based in Seoul, South Korea approved the experiments, but according to the journal, “the author did not receive an approval by the board and he used a false approval number.”

Here’s the retraction notice for “The role of compensatory movements patterns in spontaneous recovery after stroke,” published in the Journal of Physical Therapy Science (JPTS) in September 2015 and retracted in December: Continue reading Author says he lied about approval for animal research

Two retracted papers were published behind bosses’ backs

Researchers have retracted two 2016 papers from the same journal which were published without the permission of the supervising scientists.

According to the retraction notices, the two Applied Materials & Interfaces articles were “published without the full knowledge or consent of the principal investigators” who guided the research, but are not named in the notices.

The papers share the same three authors, listed in the same order. Last author Fangqiong Tang and middle author Laifeng Li are principal investigators in different labs at the Chinese Academy of Sciences in Beijing. First author Nanjing Hao was formerly in Tang’s research group, but is now at Dartmouth College in New Hampshire.

Here’s the retraction notice for “Fabrication of Carbohydrate-Conjugated Fingerprintlike Mesoporous Silica Net for the Targeted Capture of Bacteria,” which was retracted only months after it was published in November 2016: Continue reading Two retracted papers were published behind bosses’ backs

3rd retraction appears for fired Pfizer breast cancer researcher

Pfizer has retracted a paper by a former employee who was fired after the company discovered she had been doctoring data.

The retraction, in Molecular Cancer Research, is the third of five papers Pfizer asked to retract, after an investigation discovered they contained duplicated images. The papers have been discussed on PubPeer, which is also mentioned in the latest retraction notice.

As a result of the investigation, Pfizer terminated the employment of Min-Jean Yin, the last author on the newly retracted paper.

According to the notice, Yin and five of her co-authors agreed to the retraction:

Researcher who lost whistleblower lawsuit logs 4 more retractions

A brain journal has retracted four papers by a researcher due to image duplications that the university uncovered during an investigation into his work.

According to the retraction notice, Wayne State University found that Christian Kreipke had used several images in these articles “to represent different results in grant proposals and/or poster presentations,” and that the data were unreliable. Kreipke now has a total of five retractions, by our count.

As we’ve reported before, Wayne State and Kreipke have been engaged in conflict for several years. In 2012, Kreipke was dismissed from his assistant professor post at Wayne State after the university said it found evidence of research misconduct, according to Courthouse News. Kreipke fired back against the university, filing a whistleblower lawsuit. In it, Kreipke claimed that the institution was “involved in a conspiracy,” according to unsealed court documents, in which it had swindled the U.S. government out of millions in research funding.

A judge dismissed the case in 2014, but the conflict between Kreipke and Wayne State was not over. Continue reading Researcher who lost whistleblower lawsuit logs 4 more retractions
