Why retraction shouldn’t always be the end of the story

rsc-logoWhen researchers raised concerns about a 2009 Science paper regarding a new way to screen for enzymatic activity, the lead author’s institution launched an investigation. The paper was ultimately retracted in 2010, citing “errors and omissions.”

It would seem from this example that the publishing process worked, and science’s ability to self-correct cleaned up the record. But not so to researchers Ferric Fang and Arturo Casadevall.

Fang, of the University of Washington, Seattle, and Casadevall, of Johns Hopkins — who have made names for themselves by studying retractions — note today in an article for Chemistry World that

Neuroscience paper retracted after colleagues object to data publication

frontiersA paper published this October in the journal Frontiers In Neuroscience was retracted the following month because the authors’ collaborators did not give them permission to publish some of the data.

The paper detailed how and why the authors use the software program Nengo to test large simulations of nervous system networks. As part of the research, the authors tested five systems, one of which they were working on with another group. Due to a “miscommunication,” the authors thought they had received permission to publish the data; they plan to resubmit a paper describing the other four systems.

Here’s the official retraction note: Continue reading Neuroscience paper retracted after colleagues object to data publication

Authors retract chemistry letter after new data reveal problems in reaction, structure

title

The authors of a letter describing the synthesis of ketonitrones have retracted it, after new data showed that they incorrectly reported the product structures and the reaction mechanism.

We’re not sure what exactly went wrong with the original data in the letter, “Transition-Metal-Catalyzed Ring Expansion of Diazocarbonylated Cyclic N-Hydroxylamines: A New Approach to Cyclic Ketonitrones,” published in Organic Letters. 

Here’s the reaction that the paper reported, from the abstract:

Science retracts physics paper after magnetic field wasn’t what it seemed

F1.mediumScience has retracted an August paper on an interesting electric current researchers observed in a kind of material called a topological insulator. Well, a current the researchers — based at Stanford and MIT — thought they had observed.

A magnetic field with particular attributes reported in the paper seemed to provide evidence of the current. But the researchers soon discovered that the field might have been, in part, an artifact of the very device they used to detect it. The authors, along with a few other researchers, have published that subsequent finding on the physics preprint server, arXiv.

Here’s the retraction note:

In more faked peer review news…10 papers pulled by Hindawi

Screen Shot 2015-12-18 at 9.57.36 AMGuess what? We’ve got more cases of fraudulent peer review to report — our second post of the day on the subject, in fact. In the latest news, Hindawi Publishing Corporation has retracted 10 papers for “fraudulent review reports,” after an investigation of more than 30 papers that had been flagged this summer.

The investigation found that author Jason Jung, a computer engineer at Yeungnam University in Korea, “was involved in submitting the fraudulent review reports” for four of the retracted papers, according to the publisher’s CEO. In the case of the other six, the authors didn’t appear to be involved.

Hindawi Publishing Corporation, which publishes over 400 journals, doesn’t ask authors for potential review suggestions — making a common route to fake peer review more difficult.  In July, when Hindawi announced it was investigating the papers, it posted a statement saying that they suspected the editors had created fake reviewer accounts.

The retraction note on Jung’s papers — identical except for the title at the beginning — explains that each paper has

Astrophysicists issue two detailed corrections

1.coverA group of astrophysicists has notched a pair of corrections for papers on galaxy clusters, thanks to an error that affected several figures in the papers, but not the overall conclusions.

The errors came in the catalog of “mock” galaxies that first author Fabio Zandanel, a postdoc at the University of Amsterdam, created to model features that are found in clusters of galaxies. Two mistakes canceled each other out “almost perfectly,” says Zandanel, making the changes that resulted from them subtle.

Zandanel explained the errors to us:

Investigation into CT scan paper reveals plagiarism

Screen Shot 2015-12-01 at 10.02.20 AMA paper on the quality of computed tomography (CT) images of the human body didn’t stand up to a close examination. It’s been retracted after an investigation found that it plagiarized work from two publications and a poster by another researcher.

The text in the Journal of the Korean Physical Society paper was taken from work by Kenneth Weiss, a radiologist at the University of Miami, and Jane Weiss, CFO of the couple’s medical imaging company. According to emails that Jane Weiss forwarded to us, Kenneth Weiss brought the plagiarism to light after a PhD student pointed out the similarities between the JKPS paper and one of Weiss’s in the American Journal of Roentgenology. Weiss notified the AJR in January. They started an investigation into the matter, and alerted the JKPS.

The retraction note for “Measurement of image quality in CT images reconstructed with different kernels” provides more details about the investigation:

Journal repels a paper on a magnetic material after authorship, funding issues

S03048853

A paper on the properties of a magnetic material is being retracted after including an author without his permission, and omitting a funding source.

According to the note, the work was done in Miao Yu‘s lab at Chongqing University in China; the authors then added Yu’s name to the paper without his authorization, and neglected to list a relevant funding source.

Here’s the retraction note for “Temperature-dependent dynamic mechanical properties of magnetorheological elastomers under magnetic field,” published in the Journal of Magnetism and Magnetic Materials:

Chemists pull non-reproducible paper on method to make opal films

CoverIssue

When two chemists based in China couldn’t reproduce experiments in their paper on opal films, they retracted it.

As the retraction note explains:

In this article we report a method to fabricate 2D TiO2–WO3 composite inverse opal films via a mechanical co-assembly route with a template of polystyrene spheres. Upon repeating the experiments described, we found that this was not an effective method for forming the films; often the film was broken or did not form at all.

The note also explains why the experiment didn’t work:

3-D printing paper accidentally includes secrets

9

A paper on 3-D printing has been pulled because it “inadvertently” included some sensitive material.

We’re not sure which parts of the paper were the specific problem. But the sensitive material may have something with how to improve the surfaces of 3-D printed products, which is the subject of “Feasibility of using Copper(II)Oxide for additive manufacturing.”

Here’s what the paper, published in the International Journal of Precision Engineering and Manufacturing contains, according to the abstract:

Additive manufacturing, in spite of its ever wider application range, is still plagued by issues ranging from accuracy to surface finish. In this study, to address the latter issue, the feasibility of using Copper(II)Oxide powder with a polymer binder deposited through a Fused Deposition Modeling (FDM) 3D printing technique is explored.

Here’s the retraction note:
