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:

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:

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
Back in January, we wrote about the retraction of a paper in the International Journal of Radiation Oncology *Biology* Physics, the first from that journal in its 38-year history.
At the time, the journal’s new editor, Anthony Zietman, of Mass General, told us that he was working on a second retraction. That one has arrived.
The paper, “High-Dose Conformal Radiotherapy Reduces Prostate Cancer–Specific Mortality: Results of a Meta-analysis,” came from a team of radiation oncologists in Brazil, and was published last August.
According to the retraction notice:

The twelfth of Alirio Melendez’s 20-something retractions has appeared, in Clinical and Experimental Pharmacology and Physiology.
Along with the retraction notice, the journal runs letters from the paper’s two co-authors. Melendez writes: Continue reading Retraction 12 appears for Alirio Melendez, this one for plagiarism
We have an update on two papers about lung cancer screening by Claudia Henschke and colleagues that were subject to an Expression of Concern early last year.
The original Expression of Concern in Cancer read, in part: Continue reading ORI, OHRP find “some human subject issues” in Henschke lung cancer studies, but no evidence of misconduct
Last August, we reported on an Expression of Concern in the American Journal of Respiratory and Critical Care Medicine for a paper on HIV and lung injury. The notice said that the University of Nebraska, home to several of the paper’s authors, had begun an inquiry.
Today, the university issued a statement on the case, clearing the researchers of misconduct: Continue reading University of Nebraska clears HIV researchers of misconduct
