Two more papers by Diederik Stapel — who was profiled by The New York Times Magazine this weekend — have been retracted, both in the Journal of Experimental Social Psychology.
The notice for “Hardly thinking about close and distant others: On cognitive business and target closeness in social comparison effects,” by Stapel and David Marx, and cited six times: Continue reading “Unfinished business”: Diederik Stapel retraction count rises to 53
A group of researchers at the University of Minnesota have retracted a paper in Diabetes for image problems, but exactly what happened is still under investigation.
Here’s the notice: Continue reading Diabetes paper retracted for “misgrouping errors” that remain under investigation
A group of cancer researchers in Japan has retracted their 2011 paper in the journal Medicine. The reason: They seem to have had some trouble — well, perhaps a bit more than some — with their patient population.
The article, titled “Usefulness of systemic CT scanning in the detection of malignant lymphadenopathy,” came from the lab of Norio Komatsu, a hematologist at Juntendo University School of Medicine.
The paper’s no longer online, but we did find an abstract floating around: Continue reading Authors retract CT scan-cancer paper, citing faulty data
Rui Curi — the Brazilian scientist who threatened to sue the now-shuttered Science-Fraud.org site for criticizing his work — has rung up his second retraction, this one for a paper that he corrected earlier this year.
Here’s the Journal of Endocrinology notice, whose headers and language are a bit confusing, understandably, because it is retracting two things, a correction and the original paper: Continue reading Streisand Effect meets tough editors as journal retracts already-corrected paper by Rui Curi
Another paper by Milena Penkowa, who is being investigated for embezzlement as well as possible scientific misconduct, has been subject to an Expression of Concern:
Here’s the notice in Glia: Continue reading Another Expression of Concern for Milena Penkowa
A team of researchers in Ireland has retracted two papers from Cancer Letters after concerns were apparently raised about some of the studies’ figures.
Denise Egan, of the Institute of Technology Tallaght in Dublin, and colleagues published “In vitro anti-tumour and cyto-selective effects of coumarin-3-carboxylic acid and three of its hydroxylated derivatives, along with their silver-based complexes, using human epithelial carcinoma cell lines” and “A study of the role of apoptotic cell death and cell cycle events mediating the mechanism of action of 6-hydroxycoumarin-3-carboxylatosilver in human malignant hepatic cells” in 2007.
The two notices say the same thing: Continue reading Two cancer papers retracted because authors “are unable to guarantee the accuracy of some of the figures”
Nature is retracting a 2010 paper by a team from Princeton and Drexel on the workings of Plasmodium falciparum, which causes malaria in people. How that came about seems to have been a winding road.
The article — a research letter — titled “Branched tricarboxylic acid metabolism in Plasmodium falciparum,” came from the Princeton lab of Manuel Llinás. It purported to find that:

Bryan William Doreian, who was found by the Office of Research Integrity (ORI) to have falsified data in his Case Western dissertation, has retracted a 2009 paper in Molecular Biology of the Cell also cited by the ORI.
Here’s the notice: Continue reading Retraction appears for former Case Western dermatology researcher found by ORI to have falsified data
A public health journal has retracted a 2010 paper by a CDC AIDS researcher in Uganda who appears to have lifted much of the work from a Canadian scientist.
The article, “Determinants of project success among HIV/AIDS NGOs in Rakai, Uganda,” appeared in the International Journal of Health Planning and Management, a Wiley title. The author was Stevens Bechange, who was listed as being with the Uganda Virus Research Institute, in Entebbe. Bechange’s Linkedin page says he is a doctoral student at the University of East Anglia, in Norwich, UK, studying “Health, Wellness and Fitness.” His contact information on the article was an email with a CDC address (we’ve put in a call to the agency to find out more about his status but haven’t heard back yet).
As the abstract stated:
Continue reading Paper on anti-HIV efforts in Uganda pulled for plagiarism
Coding errors in a database maintained by Pfizer have led authors to retract two heart biomarker papers in the Journal of the American College of Cardiology.
The two notices, for “Prediction of cardiovascular events in statin-treated patients by lipid and non-lipid biomarkers” and “Plasma PCSK9 levels and clinical outcomes in the TNT (Treating to New Targets) Trial,” are highly detailed and say the same thing: Continue reading Pfizer database errors cause two voluminous retractions for JACC statin-biomarker papers
