Image splicing, duplications, inversions kill paper for well-known longevity researcher and alum of lab

A well-known scientist at the Massachusetts Institute of Technology who studies longevity has retracted a paper for “numerous examples of unindicated splicing of gel lanes,” as well as other problems.

This is Leonard Guarente‘s second retraction. He shares both with Gizem Donmez, an alum of his lab who now has three retractions. Donmez left her post as a Tufts professor in 2014.

Guarente told us in March — when we reported that he’d published a mega-correction on another paper — that he had planned to address issues with the paper, “SIRT1 Protects against α-Synuclein Aggregation by Activating Molecular Chaperones,” published in the The Journal of Neuroscience. Now, a retraction note has appeared “at the request of the authors.” It explains:

Philosophy journal spoofed, retracts hoax article

A philosophy journal that focuses on the teachings of philosopher Alain Badiou has apparently fallen victim to yet another Sokal hoax, and has retracted a fake article submitted by authors trying to expose the publication’s weaknesses.

The paper, “Ontology, Neutrality and the Strive for (non-)Being-Queer,” attributed to Benedetta Tripodi of the Universitatea Alexandru Ioan Cuza in Romania, is apparently the work of two academics, who submitted the absurd article to Badiou Studies to expose its lack of rigor in accepting papers.

Just a quick look at some of the text of the fake paper exposes its peculiarities. Here are the first few lines of the abstract: Continue reading Philosophy journal spoofed, retracts hoax article

Scientific misconduct and sexual harassment: Similar problems with similar solutions?

Michael Chwe
Michael Chwe

Today colleges and universities face a crisis of accountability in two domains: scientific misconduct and sexual harassment or assault.  Scientific misconduct and sexual harassment/assault are obviously different, but the way they are reported, handled, and play out have many similarities. Michael Chwe at the University of California in Los Angeles has been thinking about this for a while.  Just last summer his own department was rocked by the high-profile retraction of a Science paper about gay canvassers, and two graduate students in the UCLA history department sued the university for failing to investigate sexual harassment complaints.  Chwe suggests that, if scientific misconduct and sexual assault are similar, they might have similar solutions.

Scientific misconduct and sexual assault have more in common than you might think. Continue reading Scientific misconduct and sexual harassment: Similar problems with similar solutions?

Journal retracts groundwater pollution paper for plagiarism

ecotoxThe journal Ecotoxicology has retracted a paper that described a way to analyze nitrates in groundwater after discovering the authors had lifted a substantial amount of material from three other papers.

Here is the retraction notice for “Isotopic analysis of N and O in NO3 – by selective bacterial reduction to N2O for groundwater pollution:” Continue reading Journal retracts groundwater pollution paper for plagiarism

Does this scientific image look familiar? It’s from a catalog

cover (4)There’s something strange about a 2008 paper on the role of nicotine receptors in promoting lung cancer: One of the western blot analyses looks like a version of an image from a commercial catalog.

A commenter on PubPeer pointed out the similarities between an image in “Role of α7-nicotinic acetylcholine receptor in human non-small cell lung cancer proliferation,” which was published in Cell Proliferation, and one used to promote an enzyme sold by Cell Signaling Technology.

Unfortunately, if the images are indeed the same, we can’t tell for certain who copied from whom. But a representative of the company told us it generates its own images, and this one was likely created before the paper was published. The last author — for whom we’ve found three other retractions — denied that the paper copied the image.

Here’s the panel from the paper, which was published in 2008: Continue reading Does this scientific image look familiar? It’s from a catalog

Authors pull 14-year-old paper from PNAS over concerns of fabrication

13.coverAuthors have retracted a 2002 paper from PNAS because part of a figure “may have been fabricated,” and they no longer have the original data to prove otherwise.

The paper in question, “Deficient Smad7 expression: A putative molecular defect in scleroderma,” studied the signaling pathways that may underlie the autoimmune disease. It has been cited 198 times, according to Thomson Reuters Web of Science.

The authors, led by Pascal J Goldschmidt-Clermont, currently the Dean of the School of  Medicine at the University of Miami, have issued a retraction note, which appeared online yesterday: Continue reading Authors pull 14-year-old paper from PNAS over concerns of fabrication

Five more notices for Duke pulmonary pair brings retraction tally into double digits

Two retractions and three corrections have appeared for a group of Duke researchers that already have 10+ retractions under their belts.

The reasoning behind them echoes that which we’ve seen before in notices for Michael Foster and Erin Potts-Kant: Following an inquiry from the university, the journals were informed that some of the data or results weren’t reliable, and not all of the experiments could be repeated.

A colleague aware of the case said that researchers are still working to repeat experiments from papers by Potts-Kant and Foster. It is not known how many more papers might be corrected or retracted. Duke University is fully supporting the validation of these experiments, the source told us.

Foster has retired from Duke, a spokesperson for the university confirmed. Continue reading Five more notices for Duke pulmonary pair brings retraction tally into double digits

Now this is transparent: Retraction for plagiarism earns 4-page editor’s note

The Photogrammetric Record

A journal has retracted a paper about 3D imaging after concluding the authors used equations from another researcher without attribution — and has conveniently included a detailed editorial explaining exactly what happened.

It’s rare for us to see a journal be so transparent in explaining what went wrong with one of its papers, so we’re thanking Stuart Granshaw, from Denbighshire in Wales, UK, the editor of The Photogrammetric Record, for “doing the right thing.”

Even the retraction note is reasonably forthcoming: Continue reading Now this is transparent: Retraction for plagiarism earns 4-page editor’s note

Lancet issues expression of concern for 2011 Macchiarini paper

The Lancet has tagged an expression of concern onto a seminal 2011 paper by Paolo Macchiarini, the Italian surgeon whose work and conduct outside the operating room has earned months of  heavy criticism that recently culminated in his dismissal from the Karolinska Institutet.

“Tracheobronchial transplantation with a stem-cell-seeded bioartificial nanocomposite: a proof-of-concept study,” which described the first case of a transplant using an artificial trachea seeded with the patient’s own stem cells, now bears an expression of concern from The Lancet editors, citing ongoing investigations. The journal has also removed three more authors from the paper, upon their request.

The expression of concern essentially presents the timeline of the controversy that led the journal to make this move:

Poop paper flushed due to possible sample contamination

cover (3)The authors of a paper on a new probiotic strain of bacteria found in pig feces have retracted it from Animal Science Journal after discovering some of the bacteria might have been contaminated.

Readers likely know by now how easy it is for this to happen, as we frequently report on retractions due to similar reasons. Like other instances of mistaken cell identity, the authors of this 2013 paper realized the mistake following further tests of the bacteria used in the experiment.

The retraction for “Isolation, characterization, and effect of administration in vivo, a novel probiotic strain from pig feces”
