Insert data here … Did researcher instruct co-author to make up results for chemistry paper?

orgnd7_v032i014.inddThe chemistry blogs have been buzzing this week with the story of a paper in the journal Organometallics that may — or may not — contain fabricated data.

But what makes the story a bit juicier — and yes, it’s sad that fabricated data is a bit ho-hum for us — is that one of the authors of the article appears to have been caught in the act of instructing the first author to make up results.

The article, “Synthesis, Structure, and Catalytic Studies of Palladium and Platinum Bis-Sulfoxide Complexes,” appeared last month and came from a group at the Institute for Organic Chemistry at the University of Zurich. The authors were Emma E. Drinkel, Linglin Wu, Anthony Linden and Reto Dorta.

As ChemBark reported earlier this week:

Birds of a feather: Authors who play games with fowl data earn multiple retractions

jmicrobiotechA group of animal health researchers from the Chinese Academy of Agricultural Sciences have lost their 2009 paper in the Journal of Microbiology and Biotechnology because they’d published the data in at least four other articles.

The paper, “Two Novel Duck Antibacterial Peptides, Avian β-Defensins 9 and 10, with Antimicrobial Activity,” reported that: Continue reading Birds of a feather: Authors who play games with fowl data earn multiple retractions

That face rings a bell, but where have I published it before?

ieriprocediaIrony alert: If you’re going to write a paper about face recognition technology, well, do we really need to go on?

A group of researchers in Wuhan, China, evidently didn’t quite realize they were walking into a ridicule trap when they agreed to have their paper, “Face Recognition with Learning-based Descriptor,” published in IERI Procedia. The article appeared in 2012 and was part of an issue devote to that year’s International Conference on Future Computer Supported Education, which took place in Seoul.

And now comes this: Continue reading That face rings a bell, but where have I published it before?

“Sufficient concern” about data prompts retraction of T-cell paper

journal of immunology 8 15The Journal of Immunology has retracted a 2011 paper on T cell activity after the authors decided they couldn’t stand by the reliability of the work.

The article was titled “Human Regulatory T Cells Require IL-35 To Mediate Suppression and Infectious Tolerance.” (On Pubmed the title has the rather ironic precursor “Cutting edge” in front). Here’s the abstract: Continue reading “Sufficient concern” about data prompts retraction of T-cell paper

Anticancer-fungus paper retracted because some of the results “may be inaccurate”

biomacroMaybe it was a case of hitting the “send” button a bit too soon, or maybe it was a spasm of seller’s remorse, but a group of Chinese researchers has retracted a paper they’d published preliminarily a few months earlier.

The paper, “Antitumor and immunomodulatory activity of a polysaccharide from fungus Coprinus comatus (Mull.:Fr.) Gray,” by a group from various institutions in Shaanxi, appeared in April on the website of International Journal of Biological Macromolecules (as what appears to have been an uncorrected proof). But that didn’t stick.

According to a retraction notice dated August 2nd: Continue reading Anticancer-fungus paper retracted because some of the results “may be inaccurate”

Author stalemate in Czech DNA paper leads to retraction

Okay, so it’s not quite Kafka, but a group of forensic geneticists from Prague’s Charles University has lost a paper in Folia Biologica (a journal from that famed institution where Kafka studied) over what appears to be a rather Byzantine dispute about authorship and the quality of the data.

The 2010 article, “DNA analysis of ancient skeletal remains” was written by a trio of authors from Charles University’s Department of Anthropology and Human Genetics. According to its abstract: Continue reading Author stalemate in Czech DNA paper leads to retraction

Privacy breach prompts retraction of three papers from the trauma literature

ejpsychtraumA group of international psychology researchers is retracting three papers in the wake of revelations that they failed to adequately safeguard the identities of the patients who participated in the studies.

So far, only one article has been formally retracted. That article, “Combining biofeedback and Narrative Exposure Therapy for persistent pain and PTSD in refugees: a pilot study,” appeared last year in the European Journal of Psychotramatology. Its authors were Naser Morina, Thomas Maier, Richard Bryant, Christine Knaevelsrud, Lutz Wittmann, Michael Rufer, Ulrich Schnyder and Julia Müller.

According to the notice: Continue reading Privacy breach prompts retraction of three papers from the trauma literature

Not our problem: Journal bows out of data dispute after U Minn challenges previous statement

cellcyclecoverBack in May we reported on an Expression of Concern in Cell Cycle — a notice that had entered life as a retraction but mysteriously metamorphosed into the less dramatic form. The statement limned a rather bizarre dispute between researchers who crossed paths at the University of Minnesota and are now embroiled in litigation over ownership of the data.

Now, it gets weirder. Responding to further correspondence from the university, the journal has effectively washed its hands of the matter — without bothering to wipe down the sink or hang up the towel.

Here’s the “Comment on Expression of Concern“: Continue reading Not our problem: Journal bows out of data dispute after U Minn challenges previous statement

Neural Networks retracts rerun

neuralnetworksIrony alert: If you’re going to write articles about recurrent neural networks, make sure they don’t, well, recur.

The journal Neural Networks has retracted a 2012 paper by a group of researchers from Spain for publishing what amounted to a repeat of a 2011 article in a different but closely related journal. Scientific publishing, alas, is not like Hollywood, where remakes of movies and TV shows is not only acceptable, it seems to be the only flavor producers are willing to taste.

The article was titled “Hopf Bifurcation Stability in Hopfield Neural Networks” — Hopf, for those keeping score at home, is Eberhard Hopf, a famous (and politically controversial) mathematician and founder of something called ergodic theory — and it came from scientists at the University of La Laguna, in the Canary Islands.

According to the notice: Continue reading Neural Networks retracts rerun

Retraction of JBC heparan paper shows much to like

jcb726coverWe have knocked the Journal of Biological Chemistry in the past for what we believed to be needless — and unhelpful — obfuscation. And more recently, we have praised the journal for taking what we believe to be positive steps in the direction of greater transparency.

Here, again, we come not to bury JBC but to praise it.

The journal has issued a retraction for a 2011 article by a group of researchers in London, England, led by Stephen Perkins. The paper, “The solution structure of heparan sulfate differs from that of heparin,” purported to show that:
