According to the retraction notice in Advanced Materials, Mehdi Ghaffari — formerly based at Penn State — was solely responsible for the misconduct. Ghaffari’s LinkedIn page says he finished his PhD at Penn State in 2014, and now works as an independent consultant in New York, after a stint as a postdoc at Procter and Gamble.
A Penn State spokesperson sent us this statement: Read the rest of this entry »
Earlier this month, Morris Karmazyn, an award-winning cardiovascular researcher who’s published hundreds of papers, was called into a meeting with the office of faculty relations at the University of Western Ontario, and terminated.
The reason? A series of image problems in some of his papers, raised by a former member of his lab. When Karmazyn, Canada Research Chair in Experimental Cardiology, was told it was a case of “misconduct,” he was floored: Read the rest of this entry »
Journals have flagged two papers by prominent social psychologist Jens Förster — whose work has been subject to much scrutiny — over concerns regarding the validity of the data.
Förster already has three retractions, following an investigation by his former employer, the University of Amsterdam (UvA) in the Netherlands. In 2014, we reported on the first retraction for Förster for one of three studies with odd patterns that were flagged by the UvA investigation, a 2012 paper in Social Psychological and Personality Science; subsequently, the Netherlands Board on Research Integrity concluded that data had been manipulated. Three statistical experts from the UvA then carried out a more in-depth analysis of 24 publications by Förster, and found eight to have “strong evidence for low scientific veracity.”
Last year, Förster agreed to retract two more papers as part of a deal with the German Society for Psychology (DGPs); those retractions appeared earlier this year. All three papers that Förster has lost until now are from the “strong evidence for low scientific veracity” category. Recently, two more of Förster’s papers from the same category were flagged with notices, but not retracted.
According to an investigation report released by the ORI last year, all 11 studies co-authored by Girija Dasmahapatra, formerly based at Virginia Commonwealth University (VCU) in Richmond, will either be retracted or corrected. In April, Dasmahapatra lost the first of the 11 papers flagged by the ORI in the journal Leukemia. Earlier this month, a second paper from the list was pulled by Clinical Cancer Research.
Dasmahapatra isn’t the only VCU researcher who’s been busy correcting the literature. All 11 papers mentioned in the ORI report list Steven Grant as last author; Paul Dent is a co-author of nine of these studies. Last month, we reported on a retraction in the Journal of Biological Chemistry (JBC) and a mega-correction in Molecular Pharmacology issued for papers by Grant and Dent due to problems with images. Neither paper included Dasmahapatra as a co-author.
We’ve also previously reported on four other errata for image-related issues for papers by Dent (one of which lists Grant as a co-author). Now, we’ve come across another correction in JBC for the pair, which was published last month.
Chem paper “the product of intentional, knowing, or reckless falsification, fabrication, and plagiarism”
According to the retraction notice in RSC Advances, the first author submitted the paper without the knowledge of the other two co-authors, and the paper was falsified, fabricated, and plagiarized. The notice cites a probe at the University of Tennessee (UT) at Knoxville — where all three listed authors are based — that concluded the study’s findings were invalid.
An investigation into a scientist suing PubPeer commenters over criticisms of his work has concluded that the researcher engaged in widespread misconduct and should retract 42 papers.

According to the EOC, published in RSC Advances, the paper is now under investigation.
Parkinson’s researcher Caroline Barwood pleaded not guilty to fraud-related charges in a Brisbane courtroom Monday.
According to 9News, Barwood is accused of three counts of fraud, and four instances of attempted fraud, which include trying to obtain approximately $700,000 (AUD) from various organizations between 2011 and 2013 for a study that never occurred. The case follows an investigation at her former institution, the University of Queensland (UQ), which resulted in three of her papers being retracted.
Crown Prosecutor Caroline Marco alleged that Barwood was also intimately involved with Bruce Murdoch, her former colleague at the UQ, who has pleaded guilty to 17-fraud related charges, and received a two-year suspended sentence earlier this year.
Marco also claimed that Barwood admitted that Read the rest of this entry »
Nature Communications has issued an expression of concern for a 2014 paper by beleaguered surgeon Paolo Macchiarini, citing concerns over whether the paper accurately reports the experiments that were carried out.
According to the notice, Macchiarini, a former rising star in the field of transplant medicine, agrees with the expression of concern. Three of his 22 co-authors have objected.
“Experimental orthotopic transplantation of a tissue-engineered oesophagus in rats” describes transplanting an esophagus into rats that was seeded with their own stem cells, and notes that all animals survived the study period (14 days), and gained more weight than rats given a placebo operation. It’s a topic Macchiarini has made famous, as the first surgeon to perform a similar procedure with a human tracheal transplant. But he’s faced charges of misconduct in the last few years, resulting in his dismissal from Karolinska Institutet (KI).
We’ve previously reported on four retractions of papers by Stephanie Watkins, a researcher at Loyola Medicine. The previously issued notices — in The Journal of Clinical Investigation and Cancer Research — note that an investigation committee appointed by the National Institutes of Health (NIH) found Watkins to be solely responsible for the misconduct, with none of the co-authors aware of it.
The editor of OncoImmunology previously informed us that the journal was investigating another one of Watkins’ papers; the journal has now pulled that paper, citing “fabrication and falsification of data” in the original studies referenced in the paper.
