Language of a liar named Stapel: Can word choice be used to identify scientific fraud?

stapel_npcA pair of Cornell researchers have analyzed the works of fraudster Diederik Stapel and found linguistic tics that stand out in his fabricated articles.

David Markowitz and Jeffrey Hancock looked at 49 of the Dutch social psychologist’s papers — 24 of which included falsified data. (Stapel has lost 54 papers so far.)

According to the abstract for the article, “Linguistic Traces of a Scientific Fraud: The Case of Diederik Stapel,” which appeared in PLoS ONE: Continue reading Language of a liar named Stapel: Can word choice be used to identify scientific fraud?

PLOS ONE retraction notice blames deceased author for image manipulation

A 2011 paper in PLOS ONE has been retracted due to “inappropriately assembled” images. The issues, which were highlighted in a correction in TK, are attributed to the corresponding author, Paola Palozza, who has since passed away.

Here’s the notice for “Lycopene Inhibits NF-kB-Mediated IL-8 Expression and Changes Redox and PPARγ Signalling in Cigarette Smoke–Stimulated Macrophages,” which has been cited 33 times, according to Thomson Scientific’s Web of Knowledge: Continue reading PLOS ONE retraction notice blames deceased author for image manipulation

Authors of three retracted PLOS ONE papers to retract four more, with one researcher resigning

ChemosphereThe hits keep coming for a research group at the Institute of Microbial Technology (IMTECH) in Chandigarh, India.

Last week, we reported that PLoS ONE was retracting three papers by the research group because “there are no data available underlying this study and thus…the published results are fabricated.” Now, according to The Hindu, four more papers are being retracted:

PLOS ONE retracts breast cancer genetics paper after claim of misappropriated data

plosonePLOS ONE has retracted a 2012 article by a group of breast cancer researchers after another scientist — a leading U.S. oncologist — objected that the data came from his lab.

The paper, “GREB1 Functions as a Growth Promoter and Is Modulated by IL6/STAT3 in Breast Cancer,” came from a team composed of researchers at the Morehouse School of Medicine, Xavier University of Louisiana and the University of Miami School of Medicine. It purported to find that: Continue reading PLOS ONE retracts breast cancer genetics paper after claim of misappropriated data

PLoS ONE issues expression of concern when company won’t share bacterial strain

plosoneThe editors of PLoS ONE have issued an expression of concern for a 2014 article on a form of nitrogen-fixing bacteria called Bacillus pumilus.

The reason: The company that provided the strain of microbe used in the research won’t let other researchers look at the organism.

The article is titled “Bacillus pumilus Reveals a Remarkably High Resistance to Hydrogen Peroxide Provoked Oxidative Stress,” and it came from a group led by Stefan Handtke, of the University of Greifswald, in Germany.

Here’s the notice: Continue reading PLoS ONE issues expression of concern when company won’t share bacterial strain

Three PLOS ONE papers retracted for totally made-up data

This one comes to us from Twitter, where Willem van Schaik went to express his frustration that a PLOS ONE paper he’d edited had been retracted for fake data.

Two other papers from the same group at the Institute of Microbial Technology, Council of Scientific and Industrial Research (CSIR), Chandigarh, India, were retracted simultaneously.

We sent van Schaik an email to get a clearer picture of the situation. He responded: Continue reading Three PLOS ONE papers retracted for totally made-up data

Wayward “contractor” prompts expression of concern for PLoS ONE paper on cancer cells

logoThe editors of PLoS ONE have issued an Expression of Concern (which seems likely to become a retraction) for a 2014 paper by a group of researchers in China who claim to have been led astray by a contractor hired to “edit the language” of the report.

The article, “Arsenic Sulfide Promotes Apoptosis in Retinoid Acid Resistant Human Acute Promyelocytic Leukemic NB4-R1 Cells through Downregulation of SET Protein,” came from a group in the Department of Hematology at the First Affiliated Hospital at Xi’an Jiaotong University, and was led by Yuwang Tian, a pathologist at the General Hospital of Beijing Military Area of PLA.

Or at least that’s what the manuscript eventually said. According to the expression of concern, however, that’s not what it said initially: Continue reading Wayward “contractor” prompts expression of concern for PLoS ONE paper on cancer cells

Wrong cell line leads to retraction of kidney cancer study

plosoneA group of authors in China has retracted their December 2013 paper in PLoS ONE after realizing that they’d been studying the wrong cells.

The paper, “Up-Regulation of pVHL along with Down-Regulation of HIF-1α by NDRG2 Expression Attenuates Proliferation and Invasion in Renal Cancer Cells,” came from Lei Gao, of the Fourth Military Medical University, in Xi’an, and colleagues. It purported to find that:

Chutzpah: Authors blame PLOS ONE for failing to find plagiarism in paper on Botulinum toxin

plosonelogoHoly Chutzpah, Batman! A team of researchers in India has retracted their 2012 paper in PLoS One on botulinum toxin for plagiarism — while blaming the journal for failing to use its “soft wares” to catch the plagiarism.

The article, “Small-Molecule Quinolinol Inhibitor Identified Provides Protection against BoNT/A in Mice,” was written by a group from the Defence Research and Development Establishment, in Madhya Pradesh.

According to the retraction notice: Continue reading Chutzpah: Authors blame PLOS ONE for failing to find plagiarism in paper on Botulinum toxin
