PhD student expelled for submitting paper without co-authors’ consent

PLOS OneA PhD student has been expelled from a university in China after publishing a paper in PLOS ONE without the permission of her co-authors, and using an external company to complete some of the work. 

PLOS ONE has now retracted the paper, noting that they were tipped off to the problems by a reader who raised concerns about some of the figures. The notice states that the study’s first author, Zhenni Zhang, takes full responsibility. 

The last author of the paper — Zongfang Li from the Xi’an Jiaotong University in China — told us Zhang was his PhD student who was close to completing her PhD, but has now been expelled.

Here’s the retraction notice, issued on July 25: Continue reading PhD student expelled for submitting paper without co-authors’ consent

Researcher who sued to stop retractions earns his 7th

A diabetes researcher who sued to stop a publisher from retracting his papers has just received his seventh retraction.

The latest retraction for Mario Saad, who is based at the University of Campinas (Unicamp) in São Paulo, Brazil, is for a PLOS ONE paper (which was altered last year by a mega-correction). Although an institutional investigation found no evidence of research misconduct, the notice states:

the preparation of the figures falls below the standard of publication and therefore the authors and the editors have agreed that the correct action is to retract the article. 

Saad previously sued the American Diabetes Association (ADA) to remove expressions of concern from four of his papers published in the organisation’s flagship journal, Diabetes. However, all four of the papers were later retracted after the suit was dismissed in 2015.

PLOS ONE pulls malaria study for “inappropriate manipulation” of figures

PLOS OnePLOS ONE has retracted a malaria paper after an institutional investigation found evidence the authors had manipulated multiple figures.

According to the notice, the authors’ institution — the International Centre for Genetic Engineering and Biotechnology (ICGEB) in New Delhi, India — recommended the journal retract the paper.

Here’s the retraction notice, issued by PLOS ONE on June 30: Continue reading PLOS ONE pulls malaria study for “inappropriate manipulation” of figures

A journal has retracted a paper by a leading diabetes researcher — who has also issued three corrections — after questions about her research were raised on PubPeer.

Kathrin Maedler — who works at the University of Bremen in Germany — corrected another paper in 2014. All of the notices are dated from 2015, and all describe issues with figures.

The ongoing comments have led Maedler to carefully look through her original data, according to a statement she emailed us: Continue reading Diabetes researcher logged 1 retraction, 3 correx, after PubPeer comments

PLOS ONE retracts 2 malaria papers over doubts experiments ever took place

PLOS One

Authors have retracted a pair of PLOS ONE papers after an investigation suggested the articles might contain some fiction.

In the papers, the authors describe collecting and analyzing the DNA of mosquitoes to look for changes following the introduction of bed nets treated with insecticides to combat malaria. However, an investigation by the Institut de Recherche pour le Développement in France could not confirm some of the experiments ever took place.

Here’s the retraction notice for “How the Malaria Vector Anopheles gambiae Adapts to the Use of Insecticide-Treated Nets by African Populations,” which appears at the top of the paper:

Conservative political beliefs not linked to psychotic traits, as study claimed

American Journal of Political Science

Researchers have fixed a number of papers after mistakenly reporting that people who hold conservative political beliefs are more likely to exhibit traits associated with psychoticism, such as authoritarianism and tough-mindedness.

As one of the notices specifies, now it appears that liberal political beliefs are linked with psychoticism. That paper also swapped ideologies when reporting on people higher in neuroticism and social desirability (falsely claiming that you have socially desirable qualities); the original paper said those traits are linked with liberal beliefs, but they are more common among people with conservative values.

We’re not clear how much the corrections should inform our thinking about politics and personality traits, however, because it’s not clear from the paper how strongly those two are linked. The authors claim that the strength of the links are not important, as they do not affect the main conclusions of the papers — although some personality traits appear to correlate with political beliefs, one doesn’t cause the other, nor vice versa.

In total, three papers have been corrected by authors, and a correction has been submitted on one more.

We’ll start with an erratum that explains the backstory of the error in detail. It appears on “Correlation not Causation: The Relationship between Personality Traits and Political Ideologies,” published by the American Journal of Political Science: Continue reading Conservative political beliefs not linked to psychotic traits, as study claimed

PLOS ONE republishes removed chronic fatigue syndrome data

PLOS OnePLOS ONE has republished data that were abruptly removed two weeks ago after the authors expressed concerns they did not have permission to release them.

The dataset — de-identified information from people with chronic fatigue syndrome — was removed May 18, noting it was “published in error.” But this week, the journal republished the dataset, saying the authors’ university had been consulted, and the dataset could be released.

This paper has drawn scrutiny for its similarities to a controversial “PACE” trial of chronic fatigue syndrome.

Here’s the second correction notice for “Therapist Effects and the Impact of Early Therapeutic Alliance on Symptomatic Outcome in Chronic Fatigue Syndrome,” released June 1:

Authors reused images in three papers, concludes journal probe

JBCBiologists are retracting three papers after the journal concluded they contain reused images, designed to represent different experiments. The authors stand by the conclusions, some of which they say have been “extensively validated.”

The Journal of Biological Chemistry used image analysis software to evaluate the images, first published at least a decade ago. Unfortunately, the raw data behind the problematic images were not available. The authors have also corrected a fourth paper in another journal, and wrote on PubPeer that they are working with journals to address concerns in three more.

The papers share two authors: Mireia Duñach at the Autonomous University of Barcelona, and Antonio García de Herreros at the Institut Hospital del Mar d’Investigacions Mèdiques. A representative of the Institut Hospital del Mar d’Investigacions Mèdiques told us it is looking into Garcia de Herreros’s work.

We’ll start with “β-Catenin N- and C-terminal tails modulate the coordinated binding of adherens junction proteins to β-catenin,” which has been cited 45 times since it was published in 2002, according to Thomson Reuters Web of Science. The retraction notice says:

Epilepsy researcher gets retraction, correction after former colleague flags work

EpilipsiaEpilepsy researcher Toni Schneider has received a retraction and a correction in quick succession, after a former colleague raised red flags about the work. 

The retraction for Schneider, based at the University of Köln in Germany, is for “unintentional inclusion of erroneous data” due to limitations of the recording system used in the paper, according to the notice. 

Marco Weiergräber, a former colleague of Schneider’s, has claimed that the authors of the paper did not use the test properly. The journal editor, however, told us he believes the original analysis is an “honest mistake,” and there is “no evidence” to suggest that the authors intentionally published incorrect analyses.

Here’s the retraction notice, issued by the journal in March 2016: Continue reading Epilepsy researcher gets retraction, correction after former colleague flags work

PLOS ONE paper plagiarized from 17 articles — yes, 17

PLOSOneA PLOS ONE paper about chronic pain plagiarized from multiple sources — 17, in fact.

According to the retraction notice released by the journal last week, the paper contains “extensive verbatim use of text from other sources.”

How did this make it past the editors? The journal published the paper in 2012 — before it began screening papers for plagiarism, according to a spokesperson.

Here’s the retraction notice for “The Effect of Social Stress on Chronic Pain Perception in Female and Male Mice:”
