Retraction three for Milena Penkowa, for diabetes-exercise study

diabetesMilena Penkowa, the former University of Copenhagen scientist found by her university to have embezzled grant funds and to have possibly committed misconduct in 15 papers, has another retraction.

An international panel released its findings in July, as Nature reported then: Continue reading Retraction three for Milena Penkowa, for diabetes-exercise study

Retractions three and four for Hopkins cancer biomarker group

Paul Muchowski, a neuroscience researcher at the Gladstone Institute of Neurological Disease in San Francisco, faked data in multiple grant applications, according to findings released today by the Office of Research Integrity (ORI).

In a funded NIH grant, R01 NS054753-06A1, and two submitted grant applications, R01 NS054753-06 and R01 NS047237-06, ORI says that Muchowski “knowingly and intentionally” committed “research misconduct by falsifying and fabricating data” as follows:

ORI sanctions former Texas Tech postdoc for falsification, fabrication, plagiarism

biomed chromatographyThe Office of Research Integrity (ORI) has sanctioned a former Texas Tech postdoc for using data that had actually been generated before he joined the lab in a paper as if it were new.

Shuang-Qing Zhang, according to today’s announcement by the ORI, “engaged in research misconduct by the falsification and fabrication of plagiarized data” in a paper he claimed to have written with his supervisor, Reza Mehvar, “Determination of dextra-methylprednisolone conjugate with glycine linker in rat plasma and liver by high-performance liquid chromatography and its application in pharmacokinetics,” first published online in Biomedical Chromatography in 2009. [see update at end of post]

The work was supported by the National Institute of General Medical Sciences (NIGMS), National Institutes of Health (NIH), grant R01 GM069869. The ORI found that Zhang had: Continue reading ORI sanctions former Texas Tech postdoc for falsification, fabrication, plagiarism

Paper on how swine flu might spread to birds retracted for error

eidcoverEmerging Infectious Diseases, a CDC journal, is retracting a 2010 paper about swine flu by a group of Minnesota researchers who acknowledged misinterpreting their results.

The study, a letter titled “Triple Reassortant Swine Influenza A (H3N2) Virus in Waterfowl,” claimed to shed new light on how flu viruses might jump between species: Continue reading Paper on how swine flu might spread to birds retracted for error

Scientists retract paper because they’re “not satisfied with the quality of some of the data”

antiox and redoxA group of smoking researchers — no, not scientists who are on fire; scientists who study the effects of tobacco smoke — has retracted a 2009 article after deciding that they were no longer “satisfied with the quality of the data.”

The paper, “Cigarette Smoke–induced Oxidative/Nitrosative Stress Impairs VEGF- and Fluid Shear Stress–Mediated Signaling in Endothelial Cells,” came from the lab of Irfan Rahman, a lung disease expert at the University of Rochester. It appeared online in 2009 in Antioxidants & Redox Signaling, which will be familiar to readers watching the case of Dipak Das

Stem cell retraction leaves grad student in limbo, reveals tangled web of industry-academic ties

stem cells developmentA contested retraction in Stem Cells and Development has left the Queensland University of Technology (QUT) graduate student who fought for it in limbo, uncertain if he will earn his PhD. And many of those who didn’t want the paper retracted have a significant financial interest in a company whose work was promoted by the research — despite any lack of disclosure in the now-retracted paper.

Here’s the notice: Continue reading Stem cell retraction leaves grad student in limbo, reveals tangled web of industry-academic ties

University of La Laguna ethics committee finds evidence of misconduct in chemists’ papers

jacsat_v134i049.inddA committee at the University of La Laguna (ULL), in Spain’s Canary Islands, has found evidence of misconduct by two chemists in at least two papers. One of those authors had already been forced to retract a paper in the Journal of the American Chemical Society (JACS).

The story is complicated. Here’s a try at telling it: Continue reading University of La Laguna ethics committee finds evidence of misconduct in chemists’ papers

Sweet nothings: Buggy data force retraction of sugarcane pest paper

Publisher wants $650 to retract duplicated study

am j eng app sciWe’ve heard about a lot of barriers to retraction — author and editor stubbornness being the most frequent. But now there’s a new one: A publisher that wants to charge authors $650 to retract.

University of Colorado librarian Jeffrey Beall — who produces a frequently updated list of predatory publishers — first wrote about the case on his blog last week. Beall alerted a journal about a duplication more than two years ago, and who re-reported it earlier this month when he failed to see a retraction.

What seems to have happened, according to an email exchange between the editor of one of the journals and the two authors of the two papers, is that Pit Pruksathorn, then a PhD student at Chulalongkorn University in Bangkok, submitted a paper to the Korean Journal of Chemical Engineering, a Springer title, without letting his advisor know. Prukshathorn wrote that Continue reading Publisher wants $650 to retract duplicated study
