The Proceedings of the National Academy of Sciences (PNAS) is subjecting a much-criticized study involving Facebook that it published just two weeks ago to an Expression of Concern.
From the abstract of the original study: Continue reading Rapid mood swing: PNAS issues Expression of Concern for controversial Facebook study
Surface chemistry journal Langmuir has retracted an article on a new MRI contrast agent — but only one of the authors agreed.

A significant chapter of the nearly six-month saga of the STAP stem cell controversy has come to an end, with Nature running retraction notices for the two papers involved. The journal has also published an editorial about the case that’s worth a read.
The retractions for “Bidirectional developmental potential in reprogrammed cells with acquired pluripotency” and “Stimulus-triggered fate conversion of somatic cells into pluripotency” both read: Continue reading STAP stem cell papers officially retracted as Nature argues peer review couldn’t have detected fatal problems
A 2011 paper in Science has been subjected to an expression of concern and has led to an investigation by the Texas university where the work was done.
Here’s the expression of concern, signed by Science editor in chief Marcia McNutt (and paywalled): Continue reading Chemistry paper in Science earns expression of concern for unreliable data
A Boston doctor indicted on charges of Medicare fraud in 2007 has had a paper relating to the case retracted this month.
Abdul Razzaque Ahmed was considered something of a miracle worker by his patients, treating two rare and disfiguring skin conditions called pemphigoid and pemphigus vulgaris. He used more powerful medicines than the typical course of treatment, including a drug normally used to treat cancer.
The initial indictment stated that Ahmed mixed blood samples to falsely show a “dual diagnosis” of both diseases, and prove to Medicare that they required the more rigorous (and expensive) treatment. It also alleged that he profited massively from the government pay-outs. He was convicted of obstruction in 2007; the other charges were dropped when he agreed to forfeit assets worth $2.9 million.
Now, a 2001 paper by Ahmed, which claimed fifteen patients had a dual diagnosis, has been retracted because the samples were all mixed. Here is the retraction notice from Clinical Immunology: Continue reading Alleged Medicare cheat loses paper for data mix-up
A group of cancer genetics researchers in Italy and the U.S. has retracted three papers in the Journal of Biological Chemistry (JBC) after it became aware they had duplicated some bands in their figures.
Here are the three papers: Continue reading Cancer genetics group retracts three papers for “inappropriate presentation of data”
Melanie Pallansch-Cokonis, a former research technician at Southern Research Institute, faked data in work funded by NIH contracts and grants, according to the Office of Research Integrity (ORI).
According to the ORI’s case summary, available today in the Federal Register: Continue reading Research technician faked NIH-funded research: ORI
Dong Pyou-Han, a former researcher at Iowa State University who spiked rabbit blood samples to make it look as though a potential HIV vaccine was working, was arrested earlier this week on felony charges.
According to the Des Moines Register: Continue reading Unusual: HIV vaccine researcher who faked data arrested, faces felony charges
Check List, the “journal of species lists and distribution,” retracted a paper in February after the authors realized they hadn’t spotted a yellow-red rat snake in a strange range, but rather a green rat snake in its known home.
Here’s the notice for “New distribution and elevation records for the snake Pseudelaphe flavirufa Cope, 1867 (Squamata: Colubridae) in Oaxaca, Mexico,” as written by the authors: Continue reading Rats! Snake mistake sinks paper
The journal Blood has retracted a 2010 paper over the objections of most of its authors, two of whom were found by their university to have used “fraudulent methods” to obtain the data.
We first reported on the case of Gerold Feuer last fall. The State University of New York (SUNY) Upstate Medical Center in Syracuse fired Feuer in 2010 after determining that he had misused state funds to enrich a company he had founded, HuMurine. A court agreed with many of the university’s claims, but ordered his reinstatement in 2012.
Meanwhile, as we noted last fall: Continue reading Journal retracts stem cell study despite objections of most authors
