Cancer researcher in Germany loses multiple papers after misconduct finding

with one comment

A pathology journal is retracting two papers after an investigation at the last author’s institution in Germany found evidence of scientific misconduct.

The notice for both papers cites an investigation involving Regine Schneider-Stock, who studies cancer biology at the Friedrich Alexander-University Erlangen-Nuremberg (FAU). Meanwhile, another 2005 paper that lists Schneider-Stock as the first author was retracted in October, noting evidence of image manipulation.

The most recent retractions, from the American Journal of Pathology, note that FAU declined to provide the journal with details of its investigation beyond a prepared statement:

UCLA lab pulls two papers — one by author who admitted to misconduct

with 2 comments

A lab at the University of California, Los Angeles has retracted two papers for duplicated images.

These retractions — in the Journal of Immunology — represent the second and third retractions for the lab head; he lost another paper after one of his former students confessed to manipulating images.

Although Eriko Suzuki admitted to her actions on PubPeer in 2014, the 2007 Oncogene paper wasn’t retracted until June, 2016, when the journal issued a notice citing “data irregularities.”

Unfortunately, Suzuki’s admission in 2014 wasn’t the end of the troubles for lab head Benjamin Bonavida, who recently issued two additional retractions in the Journal of Immunology, only one of which includes Suzuki as a co-author.

Bonavida told us the university received allegations (he’s not sure from who) that some of the control gels were duplicated; he didn’t agree, but couldn’t produce the original gels to disprove it. We asked if any more retractions were coming from Bonavida, who has since retired from running a lab:

Leading diabetes researcher acted negligently, probe concludes

Kathrin Maelder

Kathrin Maedler

Several duplications in the work of a prominent diabetes researcher were the result of negligence, but there is not enough evidence to support charges of misconduct, according to an investigation at her university in Germany.

Recently, we’ve reported on several notices for papers co-authored by Kathrin Maedler, a researcher at the University of Bremen. So far, Maedler has one retraction, multiple corrections, and two expressions of concern to her name, after several of her papers were questioned on PubPeer. Previously, the University of Zurich in Switzerland — where Maedler completed her PhD in 2002 — determined there was a lack of evidence to support allegations of misconduct in papers that were part of her doctoral thesis. 

Last week, the University of Bremen released its own investigation report (in German), which we translated using One Hour Translation. It concludes that Maedler Read the rest of this entry »

Who wrote this chem paper? Author claims her name was removed without consent

without comments

Spectrochimica ActaA researcher is claiming that her former PhD students impersonated her to remove her name as a co-author on a 2015 study.   

According to an editor’s note, published in Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, the journal received confirmation from all three authors that the aforementioned researcher should be removed from the author list during proofing stage. However, the researcher whose name was omitted — Nahid Nishat of the Jamia Millia Islamia in Jamia Nagar, New Delhi, India — later contacted the journal claiming that she didn’t okay this move.  

Nishat told Retraction Watch that she believes the two listed authors on the paper wrote to the journal on her behalf to remove her name:  Read the rest of this entry »

Highly cited cancer researcher logs 8th, 9th retractions

with 12 comments

Bharat Aggarwal

Bharat Aggarwal

Bharat Aggarwal, a highly cited cancer researcher who retired last year from MD Anderson, has logged two retractions following an investigation into his work, bringing his total to nine.

Aggarwal has threatened to sue us in the past, and told us that MD Anderson has been investigating his work. Earlier this year, Biochemical Pharmacology retracted seven studies of which he is the only common author, noting the “data integrity has become questionable.” Now, he’s earned two more retractions in Molecular Pharmacology, both for “inappropriate” or “unacceptable” image manipulation.

Both of the notices are paywalled (tsk, tsk). Here’s one for “Flavopiridol suppresses tumor necrosis factor-induced activation of activator protein-1, c-Jun N-terminal kinase, p38 mitogen-activated protein kinase (MAPK), p44/p42 MAPK, and Akt, inhibits expression of antiapoptotic gene products, and enhances apoptosis through cytochrome c release and caspase activation in human myeloid cells:” Read the rest of this entry »

Philosopher earns 14th retraction for plagiarism

with 2 comments

978-1-4020-3001-7Today, we bring you a case of a serial plagiarizer.

Martin W. F. Stone was a philosophy professor at the University of Leuven — by one account “widely admired and highly respected” — until 2010, when an investigation at the school concluded that his work is “highly questionable in terms of scientific integrity.” Over the past several years, he has racked up retractions, earning his 14th this spring, and spot #30 on our leaderboard.

Stone’s retractions were brought to our attention by philosopher Michael Dougherty, who found a notice for “Michael Baius (1513–89) and the Debate on ‘Pure Nature’: Grace and Moral Agency in Sixteenth-Century Scholasticism,” a chapter in Springer’s Moral Philosophy on the Threshold of Modernity.

The retraction notice says that the chapter Read the rest of this entry »

The standard in transparency? Editor praises author honesty that led to retraction in anesthesia journal

with 5 comments


Sometimes, a junior member of the team sees things an editor-in-chief misses.

Regular readers know that we’re always delighted when we get a chance to commend researchers and journals for doing the right thing. Here’s an example that sets the standard.

Anesthesia & Analgesia (A&A) is retracting a 2015 paper which purportedly found important differences in patient outcomes based on the quality of their anesthesiologists. The trouble with the article: Read the rest of this entry »

Five more notices for Duke pulmonary pair brings retraction tally into double digits

without comments

Two retractions and three corrections have appeared for a group of Duke researchers that already have 10+ retractions under their belts.

The reasoning behind them echoes that which we’ve seen before in notices for Michael Foster and Erin Potts-Kant: Following an inquiry from the university, the journals were informed that some of the data or results weren’t reliable, and not all of the experiments could be repeated.

A colleague aware of the case said that researchers are still working to repeat experiments from papers by Potts-Kant and Foster. It is not known how many more papers might be corrected or retracted. Duke University is fully supporting the validation of these experiments, the source told us.

Foster has retired from Duke, a spokesperson for the university confirmed. Read the rest of this entry »

Poll: Should retracted papers be made available for free?

with 16 comments

RW logoRecently, Robert Geller of the University of Tokyo brought an interesting issue to our attention. In following a particular paper that had been flagged with concerns on PubPeer, he saw that the journal had eventually retracted it. Even though the journal was sold under a subscription-based model, it made the retraction notice available outside the paywall– per the recommendations of the Committee on Publication Ethics (COPE).

The paper itself now included a link to the retraction notice – also recommended by COPE – but the retracted article remained behind the paywall. In other words, to read the retracted paper, non-subscribers would have to pay 3300 Yen (about $30).

Geller contacted us, concerned that the journal was continuing to profit from a retracted paper.

It’s a question we’ve never considered before: Read the rest of this entry »

Sperm paper impaired by “corporate company” analysis

without comments

2.coverWithout a certain protein, mouse sperm have motility disorders. That’s the conclusion of a paper that has itself been stopped — by errors in the data analysis, carried out by a third-party company.

The retraction note pins the analysis, which led to faulty data, on a “corporate company.” Aside from the companies that sell the kits used for substrates, assays, and detection, there’s only one company mentioned in the paper:

Generation of the mouse model was performed by the Cyagen Company (Guangzhou, China)

However, a representative of Cyagen says it does not offer the type of analysis described by the retraction note.

Here’s the full retraction note for the 2015 paper in Biology of Reproduction (which is paywalled — tsk, tsk):
