Data were “fraudulently obtained” in epilepsy paper, probe finds

brain-research-bulletinA brain research journal has retracted a 2016 study about epilepsy after an institutional investigation determined that some of the data were taken from another published paper.

The retraction notice for the study — which appeared in Brain Research Bulletin — cites an investigation by the scientific integrity committee at Tongji University in Shanghai, China, which concluded the authors had engaged in “unethical publishing behavior.”

Here’s the retraction notice for “Clc-2 knockout attenuated experimental temporal lobe epilepsy in mice by tonic inhibition mediated by GABAA receptors:” Continue reading Data were “fraudulently obtained” in epilepsy paper, probe finds

Renewable energy researcher with troubled record loses another paper

renewable-sustainable-energy-reviewsA renewable energy researcher who recycled material in several papers — and has already agreed to withdraw 10 studies — has lost another paper.

In January, we reported that six of 10 papers flagged by an investigation into author Shyi-Min Lu have either been retracted or withdrawn. Now, Lu has lost another paper that was not among the previous ten — again, for reproducing figures from earlier works without seeking permission from original authors. This paper was on a hot topic: gas hydrates, considered to be a potential new energy source to replace oil in the 21st century.

The investigations into Lu’s work took place at the Industrial Technology Research Institute in Hsinchu, Taiwan, where he was formerly based, and the National Taiwan University, in Taipei, Taiwan, which fired Lu from his position at the university’s energy research center.

Here’s the retraction notice in Renewable and Sustainable Energy Reviews, issued last month: Continue reading Renewable energy researcher with troubled record loses another paper

Authors retract 2016 cancer study when data don’t align with figures

cell-death-and-differentiationResearchers have retracted a 2016 cancer study, citing discrepancies between the data and images presented in the paper. 

Although the retraction notice itself contains relatively little information, we’ve obtained a letter from the last author — Jun-Li Luo of The Scripps Research Institute in Jupiter, Florida — to the editor-in-chief of Cell Death and Differentiation that says a bit more. 

According to the letter, after receiving the anonymous email, Luo conducted an investigation, contacting co-authors who contributed each of the figures in question. Although Luo writes that he has no reason to suspect fraud, the researchers were not able to provide some of the original data.

PubPeer commenters have questioned figures 1, 3, 4, 5, 6 and 7 in the study, “IKKα-mediated biogenesis of miR-196a through interaction with Drosha regulates the sensitivity of cancer cells to radiotherapy.”

In the letter, Luo tells Gerry Melino, co-editor-in-chief of the journal from the University of Leicester, UK, that figures 3D and 3E were provided by the study’s first author, Xing Fang, adding: Continue reading Authors retract 2016 cancer study when data don’t align with figures

When does “overlap” become plagiarism? Here’s what PLOS ONE decided

PLOSOne

Consider this: Fragments of a PLOS ONE paper overlap with pieces of other publications. The authors used them without credit and without quotation marks.

This sounds an awful lot like plagiarism — using PLOS‘s own standards, even. But the journal isn’t calling it plagiarism. They’ve labeled this an instance of “text overlap,” a spokesperson told us, based on the amount of material that the paper shares with others.

The last author — Carlo Croce, who has two retractions under his belt — denies that he plagiarized, and says that his university has cleared him of a plagiarism charge from an anonymous whistleblower.

PLOS fixed this case last year with a correction notice — not the common course of action for a case of confirmed plagiarism. Take a look at the notice for yourself:

Social networking site privacy breach complaint prompts retraction

patients-like-meA journal has removed a paper after realizing it contained a verbatim quote from a patient that could reveal the patient’s identity.

The journal learned of the slip-up after receiving a complaint from a social networking site for patients called PatientsLikeMe, which enables people with similar conditions to connect with each other. The retracted paper — ironically about automatically sanitizing private information on social networking sites — included a brief quote from an HIV-positive user of the site, containing specific dates and infections the patient had experienced.

The corresponding author of the study in Expert Systems and Applications confirmed to us that the letter from PatientsLikeMe about two lines of text in the study triggered its removal.

The journal has republished an updated version of the paper without the problematic text. 

Here’s an excerpt from the complaint, sent by Paul Wicks, Principal Scientist and Vice President of Innovation at PatientsLikeMe, to the researchers and the journal in December 2015: Continue reading Social networking site privacy breach complaint prompts retraction

U.S. gov’t researchers withdraw climate paper after using pseudonyms

adv-space-resClimate scientists from the U.S. Department of Agriculture have withdrawn a study they wrote under eyebrow-raising pseudonyms.

The withdrawn paper, about predicting surface temperatures of planets, appeared in Advances in Space Research in August, 2015, and is authored by Den Volokin and Lark ReLlez.

Normally, a withdrawal wouldn’t raise our eyebrows, but climate scientist Gavin Schmidt pointed out on Twitter that the authors’ names are eerily similar to another pair who have published climate papers together: Ned Nikolov and Karl Zeller. Yes, that’s correct — Den Volokin and Lark ReLlez are Ned Nikolov and Karl Zeller spelled backwards. Nikolov and Zeller are currently listed as a physical scientist and a meteorologist, respectively, at the U.S. Department of Agriculture.

The notice doesn’t state the reason for withdrawal, and Pascal Willis, editor-in-chief of Advances in Space Research from the Earth Physics Institute in Paris, France, referred us to the study’s authors for more information. Elsevier, which publishes Advances in Space Research, confirmed that the paper was retracted due to an “authorship issue” — namely, that the authors had used pseudonyms.

We used the contact information listed on the paper for “Den Volokin,” and got this response: Continue reading U.S. gov’t researchers withdraw climate paper after using pseudonyms

How can we improve preclinical research? Advice from a diabetes researcher

Daniel Drucker
Daniel Drucker

By all accounts, science is facing a crisis: Too many preclinical studies aren’t reproducible, leading to wasted time and effort by researchers around the world. Today in Cell Metabolism, Daniel Drucker at the Lunenfeld-Tanenbaum Research Institute of Mount Sinai Hospital in Toronto details numerous ways to make this early research more robust. His most important advice: more transparent reporting of all results (not just the positive findings), along with quantifying, reporting, tracking, and rewarding reproducibility, for both scientists and journals and universities/research institutes.

Biologist loses second paper — again, for unvalidated figures

Cellular SignallingA researcher at Case Western Reserve University in Ohio has retracted a second paper after a review found the figures didn’t match the original data.  

Last year, we reported on a previous retraction of a paper co-authored by biologist Alan Levine in Inflammatory Bowel Diseases, which was pulled for the exact same reason; even the retraction notices use similar language. The first author on both papers is Debasmita Mandal, also listed at Case Western Reserve University.

Here’s the retraction notice for “REDOX regulation of IL-13 signaling in intestinal epithelial cells: usage of alternate pathways mediates distinct gene expression patterns,” published by Cellular Signalling: Continue reading Biologist loses second paper — again, for unvalidated figures

Peer review manipulation fells another study

Spectrochimica ActaA spectroscopy journal has retracted a 2016 study after concluding that its editors had been misled by a fake review.

According to the retraction notice, the journal — Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy — accepted the paper due to positive feedback from someone assuming the identity of an expert reviewer, using an email address provided by the author of the study.

An official from the author’s institution in Turkey informed us that it will conduct an investigation. 

Here’s the retraction notice for “Diagnosis of cervical cancer cell taken from scanning electron and atomic force microscope images of the same patients using discrete wavelet entropy energy and Jensen Shannon, Hellinger, Triangle Measure classifier:” Continue reading Peer review manipulation fells another study

Retraction appears for group whose former member was sanctioned by ORI

Journal of Biological ChemistryResearchers whose former colleague was recently reprimanded by the U.S. Office of Research Integrity (ORI) have retracted a biology paper for duplication.

The retraction includes some familiar names: The last author Steven Grant, senior author of the newly retracted study, is also the last author of 11 papers flagged in a report by the ORI in December, 2015. That report focused on Girija Dasmahapatra, a co-author of the 11 studies who was also based at at Virginia Commonwealth University (VCU). Dasmahapatra left VCU in 2015, and is not listed on the latest retraction.

The retracted paper, published in The Journal of Biological Chemistry (JBC), was also co-authored by Paul Dent, a biochemist at the VCU, who we mentioned last year when he offered to retract another paper in Molecular Pharmacology after concerns arose on PubPeer. The journal has instead issued a lengthy correction (what we call a “mega-correction”).

A VCU spokesperson told us:
