Following up: Pamela Ronald publishes updated data following two retractions

Last year, we wrote about two retractions by Pamela Ronald and colleagues, after the group found that a bacterial strain they’d been using was contaminated. The group has now published a paper in PeerJ following their investigation into what went wrong. Ronald tells us the new paper, titled “The Xanthomonas Ax21 protein is processed by … Continue reading Following up: Pamela Ronald publishes updated data following two retractions

Dutch economist Nijkamp embroiled in plagiarism and duplication scandal

The Dutch papers are reporting that Peter Nijkamp, one of the leading economists in The Netherlands, has been embroiled in what looks like a self-plagiarism scandal following the cancellation of a thesis defense by one of his graduate students because of plagiarism. We say “what looks like” because it’s tough to figure out what’s alleged … Continue reading Dutch economist Nijkamp embroiled in plagiarism and duplication scandal

Weekend reads: Who plagiarizes most? Why are women cited less often? And more

It’s been another busy week at Retraction Watch. Here’s what was happening elsewhere around the web in scientific publishing, plagiarism, and retractions:

Third retraction for Karel Bezouška, of lab break-in fame

We’ve found a third retraction for Karel Bezouška, the Czech scientist, who, as we reported this summer, broke into a lab in an attempt to tamper with experiments trying to replicate his own falsified data. The article, “Molecular Characterization of Binding of Calcium and Carbohydrates by an Early Activation Antigen of Lymphocytes CD69,” had appeared … Continue reading Third retraction for Karel Bezouška, of lab break-in fame

Melendez notches retraction 14, Lemus now stands at 12

Two researchers who have appeared frequently on Retraction Watch have racked up another retraction each. This is the fourteenth retraction for Alirio Melendez, who was found guilty of misconduct by the National University of Singapore but denies the allegations. Here’s the notice in The International Journal of Biochemistry & Cell Biology for “Environmental toxicogenomics: A … Continue reading Melendez notches retraction 14, Lemus now stands at 12

Controversial Seralini GMO-rats paper to be retracted

A heavily criticized study of the effects of genetically modified maize and the Roundup herbicide on rats is being retracted — one way or another. The paper — by Gilles Seralini and colleagues — was published in Food and Chemical Toxicology last year. There have been calls for retraction since then, along with other criticism … Continue reading Controversial Seralini GMO-rats paper to be retracted

Duplication leads to recall of toxicology paper

A group of researchers from Egypt and the United States has lost their 2010 paper in the journal Toxicology in Vitro for recycling many of their own words from a previously published manuscript. The article, “Bacterial lipopolysaccharide-induced oxidative stress in adult rat Sertoli cells in vitro,” was written by Hamdy A.A. Aly, Hany A. El-Shemy … Continue reading Duplication leads to recall of toxicology paper

He said, she said: Journal of Neuroscience expresses concern, but doesn’t pursue investigation

The Journal of Neuroscience‘s retraction notices often give us plenty to chew on, and a new Expression of Concern does the same. In the notice — for a 16-year-old paper — the journal notes three cases of what certainly sounds like image manipulation, but carefully avoids calling it that:

Data artifact claims two fruit fly papers from leading UK group — who offer model response

A team of researchers led by Daniel St. Johnston, director of the Gurdon Institute at Cambridge and a prominent developmental biologist in the UK, has lost a pair of articles after finding that their data were unreliable. But rather than “correct” the record with subsequent papers, they’ve withdrawn the problematic work. To our mind, this … Continue reading Data artifact claims two fruit fly papers from leading UK group — who offer model response

Fallout from Science’s publisher sting: Journal closes in Croatia

Science‘s John Bohannon has recently revealed the extent of poor or non-existent peer review in some journals that call themselves peer-reviewed, as we reported on here. Now, an open-access publisher based in Rijeka, Croatia, called InTech, has cancelled its journal that was targeted and exposed by Science’s investigation. The journal was going to charge 400 euros to … Continue reading Fallout from Science’s publisher sting: Journal closes in Croatia
