Biofuels paper burned by “improper citation methods” – ie, plagiarism

crestCritical Reviews in Environmental Science and Technology (CRESThas retracted a paper on biofuels for “improper citation methods.”

Given the journal’s track record, we’re guessing this is just another euphemism for plagiarism. (Also because the retraction notice flags a “breach of warranties made by the authors with respect to originality.”) In 2013, CREST retracted two papers for failing to use “proper citation,” which earned it top billing in our Lab Times column about publishers’ seemingly allergic reactions to the P-word.

Here’s some of the notice for “Promising Unconventional Pretreatments for Lignocellulosic Biomass”, which described new ways to process plant biomaterials into fuel: Continue reading Biofuels paper burned by “improper citation methods” – ie, plagiarism

Misconduct dissolves paper on possible clot-busters

amclct_v006i002.inddDrug researchers in India have lost their 2013 paper in ACS Medicinal Chemistry Letters because the first author fabricated findings.

The article, by a group from the Maharaja Sayajirao University of Baroda, Vadodara, in Gujarat, was attempting to synthesize and screen novel clot-busting drugs; one compound exhibited the same activity as aspirin or warfarin, but without increasing bleeding time.

Sadly, it appears as if this potential medical advance was not to be. Here’s the retraction notice for “Novel 2-Aminobenzamides as Potential Orally Active Antithrombotic Agents”: Continue reading Misconduct dissolves paper on possible clot-busters

Chinese heavy metal contamination paper purged for data theft

Environmental_Monitoring_and_AssessmentAn environmental journal has retracted a paper about pollution in China after it discovered the authors lifted the dataset from another group.

The authors of the study — which chronicled the degree of heavy metal pollution on the banks of the Pearl River Delta — didn’t have permission to use the data. Environmental Monitoring and Assessment‘s notice doesn’t suggest the data are inaccurate.

The heavy metals in the soil come from the many manufacturing plants in the area, including those that provide the West with blue jeans, phones, and other electronics. The pollutants’ effects are wide-reaching: According to the South China Morning Post, industrial outfits discharge huge volumes of toxic chemicals into the Pearl River, including arsenic, copper, cadmium, and mercury.

It hasn’t been a good week for scientists going to court to silence criticism of their work.

Yesterday, PubPeer won a near-complete victory in a case seeking the identities of their commenters. And also yesterday, a Massachusetts judge struck down — for the second time — a request by Mario Saad to remove expressions of concern about four of his papers in Diabetes.

In his ruling, Judge Timothy Hillman wrote: Continue reading Researcher loses second bid to quash Diabetes expressions of concern

Sun sets on Sun Yat-sen University cell bio paper

j cell scienceResearchers at Sun Yat-sen University in China have lost a paper in the Journal of Cell Science for “inappropriate figure manipulations,” which they blame entirely on the first author.

According to the notice, three figures were “inappropriately modified” — cells or nuclei were moved, and the edges of cell images were trimmed. The researchers place the responsibility on first author Liping Chen, claiming that “her co-authors were completely unaware.”

The modifications didn’t affect the conclusions, the note says, but after an investigation by Sun Yat-sen University, the journal decided to retract the paper. Liping Chen says she “regrets the inappropriate figure manipulations,” according to the note.

Diabetes researcher won’t give up court fight to quash expressions of concern

Apparently, you can’t keep Mario Saad down.

The researcher, who had 12 figures in a paper corrected this week, was dealt a setback last week when a judge denied his motion to remove expressions of concern on four of his papers in the journal Diabetes, saying that would have amounted to prior restraint — essentially, censorship (a no-no, thanks to the First Amendment).

Saad and his attorneys, however, were undeterred. They filed a motion for reconsideration just four days later, along with a brief, arguing: Continue reading Diabetes researcher won’t give up court fight to quash expressions of concern

Second exercise study retracted in four-paper pileup

nursing and health scienceWe recently wrote about three papers on heart health and exercise that came under fire for reporting the same trial in three different ways. Actually, make that four ways (so far).

The Wiley journal Nursing and Health Sciences has retracted a fourth paper from the group, saying the “main study” was “previously published.” The notice mentions all three previous papers, one of which has already been retracted and another withdrawn from publication.

Here’s the notice for “Can the transtheoretical model motivate patients with coronary heart disease to exercise?”: Continue reading Second exercise study retracted in four-paper pileup

PLoS ONE mega-correction, but no retraction, for researcher who sued diabetes journal

PLoS ONE has just issued a 12-figure correction on a paper by Mario A. Saad, who sued the American Diabetes Association unsuccessfully in an attempt to prevent it from retracting four papers in its flagship journal Diabetes.

The corrections include taking out Western blots copied from another Saad paper, as well as several figures where the bands were “misplaced.”

PubPeer commenters suggest this may not be enough, calling seven additional figures into question. Continue reading PLoS ONE mega-correction, but no retraction, for researcher who sued diabetes journal

Catalyst for change: grad student catches error in chem experiments, prompts retraction

acscatalysisACS Catalysis has retracted a 2012 research letter from a chemistry lab that discovered an error in their experiments.

According to last author Rory Waterman at the University of Vermont, an undetected reaction caused his lab to mistakenly mischaracterize the products of an iridium catalyst. The diligence of a graduate student brought it all to light, he noted: “In short, it was the ability of one of my group members to be a very good scientist.”

The letter, titled “High Activity and Selectivity for Silane Dehydrocoupling by an Iridium Catalyst,” was published in February. It has only accumulated 5 citations, according to Thomson Scientific’s Web of Knowledge.

According to the retraction notice: Continue reading Catalyst for change: grad student catches error in chem experiments, prompts retraction

Heart journal issues expression of concern after fraud report

circulationThe American Heart Association’s journal Circulation has issued an expression of concern for a paper about the molecular underpinnings of arrhythmias that was co-authored by a biomedical engineer who committed fraud on a massive scale.

According to an investigation by the Office of Research Integrity (ORI), former Vanderbilt engineer Igor Dzhura faked nearly 70 images and drastically over-estimated the number of experiments he conducted. He was banned from receiving federal funding for three years.

The fraud has resulted in six retracted papers, Dzhura has agreed to retract six papers, which have been cited more than 500 times. [Ed. note: at this time, only one paper has actually been retracted]
