Paper plagiarizes from handwritten manuscript

semiform groupThis case of plagiarism is a little weirder than usual.

A paper has been retracted from Semigroup Forum because it includes material taken from another researcher’s manuscript — which was handwritten. In fact, the same journal had already published a paper by the plagiarized researcher, also based on the same manuscript. The journal editor told us that, although the two papers are similar, they are not word-for-word copies, and thus escaped detection.

The retraction notice for “Varieties of bands with a semilattice transversal” gives more details about the handwritten manuscript:

Researcher who sued to stop retractions gets his sixth

A sixth retraction has appeared for a diabetes researcher who previously sued a publisher to try to stop his papers from being retracted.

Mario Saad‘s latest retraction, in PLOS Biology, stems from inadvertent duplications, according to the authors.  Though an investigation at Saad’s institution — the University of Campinas in Brazil — found no evidence of misconduct, a critic of the paper told The Scientist he does not believe that the issues with blots were inadvertent.

Previously, Saad sued the American Diabetes Association to remove four expressions of concern from his papers; they were later retracted, even though Unicamp recommended keeping three of them published.

Here’s the new retraction notice, for “Gut Microbiota Is a Key Modulator of Insulin Resistance in TLR 2 Knockout Mice:” Continue reading Researcher who sued to stop retractions gets his sixth

Context matters when replicating experiments, argues study

PNASBackground factors such as culture, location, population, or time of day affect the success rates of replication experiments, a new study suggests.

The study, published today in the Proceedings of the National Academy of Sciences, used data from the psychology replication project, which found only 39 out of 100 experiments live up to their original claims. The authors conclude that more “contextually sensitive” papers — those whose background factors are more likely to affect their replicability — are slightly less likely to be reproduced successfully.

They summarize their results in the paper:

“Lack of scientific contributions and novelty” fells math paper

A journal apparently changed its mind about the uniqueness of a math paper, published last year.

We’ll get right to the brief retraction notice:  Continue reading “Lack of scientific contributions and novelty” fells math paper

Editors say they missed “fairly obvious clues” of third party tampering, publish fake peer reviews

BJCP Cover

The editors of a journal that recently retracted a paper after the peer-review process was “compromised” have published the fake reviews, along with additional details about the case.

In the editorial titled “Organised crime against the academic peer review system,” Adam Cohen and other editors at the British Journal of Clinical Pharmacology say they missed “several fairly obvious clues that should have set alarm bells ringing.” For instance, the glowing reviews from supposed high-profile researchers at Ivy League institutions were returned within a few days, were riddled with grammar problems, and the authors had no previous publications. 

The case is one of many we’ve recently seen in which papers are pulled due to actions of a third party. 

The paper was submitted on August 5, 2015. From the beginning, the timing was suspect, Cohen — the director for the Centre for Human Drug Research in The Netherlands — and his colleagues note: Continue reading Editors say they missed “fairly obvious clues” of third party tampering, publish fake peer reviews

PLOS editors discussing authors’ decision to remove chronic fatigue syndrome data

After PLOS ONE allowed authors to remove a dataset from a paper on chronic fatigue syndrome, the editors are now “discussing the matter” with the researchers, given the journal’s requirements about data availability.

As Leonid Schneider reported earlier today, the 2015 paper was corrected May 18 to remove an entire dataset; the authors note that they were not allowed to publish anonymized patient data, but can release it to researchers upon request. The journal, however, requires that authors make their data fully available.

Here’s the correction notice: Continue reading PLOS editors discussing authors’ decision to remove chronic fatigue syndrome data

Authors retract non-reproducible Cell paper

CellAuthors have retracted a paper from Cell after they were unable to reproduce data in two figures, compromising their confidence in some of the findings.

The authors revisited their experiments after another lab was unable to replicate their data, about proteins that may play a role in lung cancer.

The first author told Nature News in 2013 that the paper may have helped her secure her current position at the Novartis Institutes for Biomedical Research in Massachusetts.

Pulling “Cytohesins are cytoplasmic ErbB receptor activators” appears to be a case of doing the right thing, given the detailed retraction notice:

Structural biology corrections highlight best of the scientific process

Nature_latest-coverIf you need evidence of the value of transparency in science, check out a pair of recent corrections in the structural biology literature.

This past August, researchers led by Qiu-Xing Jiang at the University of Texas Southwestern Medical Center corrected their study, first published in February 2014 in eLife, of prion-like protein aggregates called MAVS filaments, to which they had ascribed the incorrect “helical symmetry.” In March, Richard Blumberg of Harvard Medical School, and colleagues corrected their 2014 Nature study of a protein complex called CEACAM1/TIM-3, whose structure they had attempted to solve using x-ray crystallography.

In both cases, external researchers were able to download and reanalyze the authors’ own data from public data repositories, making it quickly apparent what had gone wrong and how it needed to be fixed — highlighting the very best of a scientific process that is supposed to be self-correcting and collaborative.

Software glitch — not intentional manipulation — sunk immunology paper, says author

A black box appears over the control lane on the left

New evidence suggests a retracted paper was felled not by intentional manipulation — as it first appeared — but by a software glitch.

In 2014, we reported that Biochemical Journal had retracted a paper on suspicion it contained “shoddy Photoshopping”  — someone appeared to have blacked out a control lane in one figure. Now there’s evidence that it wasn’t done on purpose: An investigation at Duke into eight papers, including the Biochemical Journal paper, did not find evidence of misconduct; lead author Paul Kuo, currently chair of surgery at Loyola Medicine, told us that a glitch in the software caused the black box. Nevertheless, the journal does not plan to un-retract the paper. Continue reading Software glitch — not intentional manipulation — sunk immunology paper, says author

Journal pulls parasite paper over potential for patient harm

Parasitology ResearchA journal has retracted a paper about a molecular diagnosis for leishmaniasis out of concern it could lead to incorrect clinical diagnoses. 

According to Parasitology Research, all data behind the figures in the main manuscript and supporting information are correct, but the authors’ misinterpretation of the data could lead doctors to diagnose patients incorrectly. 

Let’s take a look at the retraction notice, which tells us a bit more about the nature of the problem: Continue reading Journal pulls parasite paper over potential for patient harm
