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
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
A court in the Netherlands has fined Vrije Universiteit Amsterdam (VU) 7,500 euros to compensate for “immaterial damage” to an economist accused of plagiarism.
Karima Kourtit, a researcher at VU, has been at the receiving end of anonymous complaints to her institution accusing her of plagiarism and her professor, high-profile economist Peter Nijkamp, of duplication (i.e. self-plagiarism). Kourtit is now seeking to prosecute the unnamed source of the complaint for defamation; the VU told us it will no longer accept fully anonymous complaints.
The case began when VU cancelled Kourtit’s thesis defense for plagiarism, and a report published on the VSNU, the Association of Universities, accused Nijkamp of self-plagiarism. Two of Nijkamp’s papers have been retracted as a result of the investigation; Kourtit is an author on one of the retracted papers.
A VU spokesperson told us:

Authors 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:

If 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.

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
Scientific fraud isn’t what keeps Andrew Gelman, a professor of statistics at Columbia University in New York, up at night. Rather, it’s the sheer number of unreliable studies — uncorrected, unretracted — that have littered the literature. He tells us more, below.
Whatever the vast majority of retractions are, they’re a tiny fraction of the number of papers that are just wrong — by which I mean they present no good empirical evidence for their claims.
I’ve personally had to correct two of my published articles. Continue reading Retractions aren’t enough: Why science has bigger problems
A 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
A 2015 study about dietary emulsifiers has been corrected by Nature after another researcher pointed out a few ambiguities.
When it first appeared, the study — which showed emulsifiers cause inflammation in the guts of mice — received a fair amount of media attention, including from Nature’s own news department. But since publication, a researcher noted some imprecision around the ages of mice used in the sample, affecting the paper’s calculations of weight gain over time. Andrew Gewirtz, co-author of the study from Georgia State University, told us the change did not affect the conclusions of the paper.
Here’s the corrigendum for “Dietary emulsifiers impact the mouse gut microbiota promoting colitis and metabolic syndrome”: Continue reading Nature fixes highly cited paper suggesting food additives hurt the gut
