Chem journal cautions readers about data in three papers

A chemistry journal has issued expressions of concern for three papers after a reader notified the editors of “unexplained discrepancies” in the data.

According to the notices, after the editors of Organic & Biomolecular Chemistry confirmed the problems, they contacted the corresponding author on the three papers, Pradeep Kumar—who works at the Council of Scientific and Industrial Research (CSIR)-National Chemical Laboratory in Pune, India—as well as the director of CSIR, Ashwini Kumar Nangia. The institution conducted its own internal review of the spectra and concluded the authors did not intentionally alter them.

Still, the journal and institution could not confirm the accuracy of the data, and the journal published expressions of concern to warn readers about the issues.

Here’s the expression of concern for “A general and concise asymmetric synthesis of sphingosine, safingol and phytosphingosines via tethered aminohydroxylation:”

Chemistry journal issues correction longer than original paper

A 2011 chemistry paper required corrections so extensive that the author published the changes as a second, longer paper.

Both papers, published in the Chinese Journal of Chemistry, described the synthesis of a protein molecule with potential therapeutic applications in cancer. But when the paper’s corresponding author Yikang Wu tried to continue the work, he discovered that a substantial part of the 2011 study was incorrect.

The original paper is not marked with any editor’s note, even though the new paper — which is three pages longer than the 2011 version — acknowledges it is a “partial retraction/correction of previous results.” The new paper does appear in the list of “related content” for the 2011 article.

Given the errors, in the 2017 paper, Wu and his co-authors write: Continue reading Chemistry journal issues correction longer than original paper

Two more retractions for former US prof who altered dozens of images

Two journals have retracted papers by a biologist who was recently found guilty of misconduct by his former employer, the University of Colorado Denver, bringing the total to five.

The investigation report by UC Denver, which we obtained earlier this year via a public records request, had recommended one of the two newest retractions, which appears in the journal Hepatology. The other retraction, in the Journal of Immunology, was not flagged by the report — which found, among other conclusions, that Almut Grenz had altered multiple values in research that had already been submitted for peer review.

Here’s the notice for the Journal of Immunology paper:

Authorship for sale: Some journals willing to add authors to papers they didn’t write

Got $300? Then you can be added as an author to a paper — even if you had no role in the research.

That’s right — some journals are willing to add authors to papers they didn’t write, often for a fee. This realization comes from one of the many sting experiments we’ve witnessed over the years, designed to expose the perils of the publishing industry, in which some journals will claim to peer review and publish any manuscript for a fee — no matter how nonsensical the content. Pravin Bolshete, a medical writer and researcher from India, wanted to explore a different side of predatory publishing — would journals agree to add a fictional author to a manuscript he/she didn’t write?

Presenting his findings at the Eighth Peer Review Congress this week in Chicago, Bolshete reported that, after sending hundreds of emails to publishers considered predatory according to the now-defunct (and controversial) list compiled by librarian Jeffrey Beall, 16% agreed to add an author to a paper.

Bolshete told us:

Pay to play: Scientists are bristling over the cost of a common research tool

A commonly used questionnaire designed to predict how well patients will stick to their drug regimen is stirring up some controversy in the publishing world. Continue reading Pay to play: Scientists are bristling over the cost of a common research tool

Copenhagen revokes degree of controversial neuroscientist Milena Penkowa

The University of Copenhagen has stripped Milena Penkowa of her doctoral degree, after determining she had covered up problems with her research.

According to a release issued today by the university, Penkowa falsified documents to allay suspicions that she had not performed some animal experiments as she’d reported.

This development is the latest in a long story: In 2015, the Copenhagen City Court ruled that Penkowa had forged experiments as part of her thesis, and handed her a nine-month suspended sentence. Penkowa appealed that ruling, and last year, another court dismissed the most serious charges.

But there was enough evidence for the University of Copenhagen’s Faculty’s Academic Council to vote unanimously last week to revoke her degree:

Bone researcher is up to 17 retractions

A bone researcher has lost three more papers for scientific misconduct.

The new retractions bring Yoshihiro Sato’s total to 17 and put him on our Leaderboard.

According to the retraction notices, Sato asked the Journal of Neurology, Neurosurgery, and Psychiatry to retract three of his papers “due to scientific misconduct.” In the letter, Sato—who is corresponding author on all three papers—explained he included co-authors without their consent and that none of the other authors listed worked on the study or article.

In May, the editors issued expressions of concern while they investigated (1, 2, 3), and last month, the journal retracted the three articles.

Here’s the retraction notice for “Amelioration of osteopenia and hypovitaminosis D by 1alpha-hydroxyvitamin D3 in elderly patients with Parkinson’s disease:” Continue reading Bone researcher is up to 17 retractions

Fertility docs said their study didn’t need ethics review. An investigation said they were wrong.

A journal is retracting a paper on the relative merits of one fertility procedure compared to another because the study never received ethical review or approval.

In the paper, “Intracytoplasmic morphologically selected sperm injection versus conventional intracytoplasmic sperm injection: a randomized controlled trial,” originally published Aug. 27, 2015 in Reproductive Biology and Endocrinology, the authors wrote: Continue reading Fertility docs said their study didn’t need ethics review.

Rowdy Roddy Pilferer: Wrestling journal takes down plagiarized paper

A journal devoted to wrestling science — we’re not sure if it’s the only one — has given the old reverse frankensteiner to a 2016 article whose authors stole much of their text from a conference presentation one of them had reviewed for the meeting.

The article, “The Role of Goal Setting, Collectivism, and Task Orientation on Iranian Wrestling Teams Performance,” appeared in International Journal of Wrestling Science, a Taylor & Francis title. Its two authors were Hossein Abdolmaleki and Seyyed Bahador Zakizadeh, of the Islamic Azad University in Karaj, Iran.

Here’s the notice: Continue reading Rowdy Roddy Pilferer: Wrestling journal takes down plagiarized paper

Authors withdraw study, citing “accidentally duplicated” images

Researchers in Australia have withdrawn a 2006 paper in The Journal of Biological Chemistry (JBC), citing image duplication.

In the withdrawal notice, published July 14, 2017, the authors claim that the “errors do not impact the underlying scientific findings of the article.”

Although the notice does not mention an investigation, a comment on PubPeer on March 2017—signed by Mark Hargreaves, the vice-chancellor at the University of Melbourne—indicates that the university conducted an investigation to assess the issues in the paper and determined that research misconduct “did not occur.”

Here’s the withdrawal notice for “Induction of the unfolded protein response in familial amyotrophic lateral sclerosis and association of protein-disulfide isomerase with superoxide dismutase 1:” Continue reading Authors withdraw study, citing “accidentally duplicated” images
