Drug researchers retract two papers, one because “human stem cells were actually mouse stem cells”

A group of drug researchers has lost a pair of 2020 papers for a lack of reproducibility and other problems, including the unfortunate mislabeling of murine stem cells as having come from humans. (In case you’re wondering, mouse and human stem cells are at once quite similar and highly divergent.)

One article, “Divergent synthesis of 5-substituted pyrimidine 2′-deoxynucleosides and their incorporation into oligodeoxynucleotides for the survey of uracil DNA glycosylases,” appeared in Chemical Science. The second, “Convenient synthesis of pyrimidine 2′-deoxyribonucleoside monophosphates with important epigenetic marks at the 5-position,” was published in Organic & Biomolecular Chemistry. Both journals belong to the Royal Society of Chemistry.

The senior author on the papers was Yana Cen, a medicinal chemist now at Virginia Commonwealth University in Richmond. Cen has not responded to a request for comment.

According to the abstract of the Chemical Science paper:

Elsevier journals ask Retraction Watch to review COVID-19 papers

Ivan Oransky: Not a COVID-19 expert

At the risk of breaking the Fourth Wall, here’s a story about peer reviews that weren’t — and shouldn’t have been.

Since mid-February, four different Elsevier journals have invited me to review papers about COVID-19. Now, it is true that we will occasionally review — often with our researcher, Alison Abritis — papers on retractions and closely related issues. And at the risk of creating more work for ourselves, we often wonder who exactly reviewed some of the papers we see published, given how badly they mangle retraction data.

These manuscripts, however, had nothing whatsoever to do with retractions. In case you need evidence, here it is:

Authors retract Nature Majorana paper, apologize for “insufficient scientific rigour”

The authors of a Nature paper that could have meant a great leap forward for Microsoft’s computing power are retracting it today after other researchers flagged serious problems in the work.

The researchers, led by Leo Kouwenhoven, a physicist at Delft Technical University in the Netherlands who is also employed by Microsoft, published “Quantized Majorana conductance” on March 28, 2018. Along with work at other labs, the paper, which claimed to have found evidence for a long-elusive particle known as a Majorana fermion, prompted this quotation in a BBC story:

Journal flags a dozen papers as likely paper mill products a year after sleuths identified them

A journal has issued a dozen expressions of concern over articles that a group of data sleuths had flagged last year on PubPeer as showing signs of having been cranked out by a paper mill.

The 12 articles were published between 2017 and 2019 in the International Journal of Immunopathology and Pharmacology and were written by authors in China. They carry the same notice:

The week at Retraction Watch featured:

“I absolutely stand by the validity of the science” says author of energy field paper now flagged by journal
What happened when a group of sleuths flagged more than 30 papers with errors?
“The right decision”: Group retracts Nature Chemical Biology paper after finding a key error
Legal researcher who claimed false affiliation up to 31 retractions
University of New Mexico investigation finds manipulated data and images, prompts retractions

Our list of retracted or withdrawn COVID-19 papers is up to 86.

Here’s what was happening elsewhere (some of these items may be paywalled, metered access, or require free registration to read):

An author loses a fifth paper because it “bears the hallmarks of plagiarism”

A researcher in France has lost his fifth paper for plagiarism, this one a 2015 article on weakness in the elderly.

The study, “Identification of biological markers for better characterization of older subjects with physical frailty and sarcopenia,” appeared in Translational Neuroscience and came from a group in France led by Bertrand Fougère, of the Universitaire de Toulouse.

As we reported in 2019, Fougère had tallied previous retractions for plagiarism dating back to 2018. At the time, he told us:

University of Tennessee investigation finds manipulated images in Science paper

An investigation by the University of Tennessee Health Sciences Center, in Memphis, into a 2006 Science paper found evidence that three figures in the article had been manipulated.

Science sleuth Elisabeth Bik first flagged the paper, titled “Molecular Linkage Between the Kinase ATM and NF-κB Signaling in Response to Genotoxic Stimuli,” to the editors of Science in 2015. Today, Science issued an expression of concern for the paper:

University of New Mexico investigation finds manipulated data and images, prompts retractions

A research group at the University of New Mexico has lost at least two papers after an inquiry found evidence of manipulated data.

One article, “Large-Area Semiconducting Graphene Nanomesh Tailored by Interferometric Lithography,” appeared in 2015 in Scientific Reports, a Springer Nature title, and has been cited 25 times, according to Clarivate Analytics’ Web of Science.

The other, “Vertical Charge Transfer and Lateral Transport in Graphene/Germanium Heterostructures,” was published in 2017 in the American Chemical Society’s journal Applied Materials & Interfaces. It has been cited twice.

The senior author on both articles was Sanjay Krishna, who has since moved to the Ohio State University, where he is the George R. Smith Chair in Electrical and Computer Engineering.

The retraction notice for the paper in Scientific Reports states:

Legal researcher who claimed false affiliation up to 31 retractions

A law researcher who has falsely claimed to have been affiliated with several institutions has lost eight more publications, bringing his retraction total to 31 and earning him a spot in the top 20 of our leaderboard.

The most recent retractions for Dimitris Liakopoulos include The Regulation of Transnational Mergers in International and European Law, an entire book he co-authored. They also include three papers from Homa Publica and two from Lex et Scientia International Journal. An example:

“The right decision”: Group retracts Nature Chemical Biology paper after finding a key error

Nicola Smith, credit Karl Welsch, Welsch Photography

Researchers in Australia have retracted a 2016 paper in Nature Chemical Biology after discovering a critical error in their research, bringing some closure to a gut-wrenching case for the scientists involved.

As we reported in January, Nicola Smith, the senior author of the article, titled “Orphan receptor ligand discovery by pickpocketing pharmacological neighbors,” described learning of the error as “the most horrific time” of her career.

Smith, then at the Victor Chang Cardiac Research Institute in Sydney (she’s now at the Orphan Receptor Laboratory at the University of New South Wales) told us that she briefly considered letting the flawed research — which has been cited 26 times, according to Clarivate Analytics’ Web of Science — go uncorrected.

After all, as one colleague told her, the subject of the studies was so arcane that
