“Immorally” affecting the literature: Authors blame sloppy work from an outside lab for retraction

SpandidosA group of Chinese researchers has retracted a paper, saying that an outside lab switched their immunofluorescent stains with another research group’s.

The group has decided to repeat the experiments on their own next time.

Here’s the notice in Molecular Medicine Reports for “Protective role of Klotho on cardiomyocytes upon hypoxia/reoxygenation via downregulation of Akt and FOXO1 phosphorylation”: Continue reading “Immorally” affecting the literature: Authors blame sloppy work from an outside lab for retraction

Former Pitt cancer researcher admits to faking findings

A former researcher at the University of Pittsburgh inflated the number of mice used in his experiments, and faked data in a number of images in a paper reporting the results, according to the Office of Research Integrity (ORI).

Dong Xiao admitting to having

intentionally fabricated data contained in a paper entitled ‘Guggulsterone inhibits prostate cancer growth via inactivation of Akt regulated by ATP citrate signaling,’ specifically Figure 6G,

the ORI reports. The paper was published in  in July 2014 in Oncotarget. Here’s Figure 6: Continue reading Former Pitt cancer researcher admits to faking findings

Cut and paste and a PC crash: figure manipulations sink two papers

jnc

Two papers by an overlapping group of researchers in Italy have been retracted for manipulated figures.

In late 2013, perennial tipster Clare Francis sent their concerns about several papers, including the two that have been retracted, by authors who frequently publish together. One of the papers, in the Journal of Neurochemistry, is from a team led by Ferdinando Nicoletti; four other papers from the group have been criticized on PubPeer for image manipulation, which he addressed via email with us.

The second retracted paper, from the Journal of Immunology, has shares one author with the first: Patrizia Di Iorio of the University of Chieti, though according to Nicoletti she had no role in preparing the figures.

Here’s the April 2014 notice for “Neuroprotection mediated by glial group-II metabotropic glutamate receptors requires the activation of the MAP kinase and the phosphatidylinositol-3-kinase pathways” in the Journal of Neurochemistry. It’s behind a paywall, but the journal has assured us this is against policy and they will be fixing it shortly:

Authors get away with throwing quotation marks around plagiarized passages. Again.

PNAS jan15Back in November 2013, we wrote about a correction in PNAS about a May 2012 paper by a group from Toronto and Mount Sinai in New York who, as we said at the time

had been rather too liberal in their use of text from a previously published paper by another researcher — what we might call plagiarism, in a less charitable mood.

Stem cell researcher Jacob Hanna responds to criticism

Over the past few months, there has been a great deal of criticism of the work of stem cell researcher Jacob Hanna, especially on PubPeer.

Now, Hanna has responded in the comments of the PubPeer entries for a number of papers. He has also posted a number of PDFs, including his PhD thesis, and correspondence with scientists who have been critical of his work.

He also wrote a response to a criticism published on bioRxIV, a non-peer reviewed repository of biology pre-prints.

One of Hanna’s comments on PubPeer is a summary of the issues with his Blood paper on PubPeer, blaming the figure errors on “medical trainees” who did the word while he was away at Mount Sinai. Here’s his explanation:  Continue reading Stem cell researcher Jacob Hanna responds to criticism

Retracted paper on herbicide-ovarian cancer connection republished

ehpA retracted 2008 paper originally flagged by Clare Francis has been republished in Environmental Health Perspectives with updated figures and new data.

According to the editor’s note appended to the newly published paper, there was no evidence of intentional misconduct on the part of the authors. The new paper went through peer review as an entirely new submission, and comes to the same conclusion as the original:  Continue reading Retracted paper on herbicide-ovarian cancer connection republished

Prominent geneticist nets retraction, two corrections, and a lot of questions

A team led by David Latchman, a geneticist and administrator at University College London, has notched a mysterious retraction in the Journal of Biological Chemistry, and has had 25 more papers questioned on PubPeer.

The JBC notice for “Antiapoptotic activity of the free caspase recruitment domain of procaspase-9: A novel endogenous rescue pathway in cell death” is as useless as they come, a regular occurrence for the journal: Continue reading Prominent geneticist nets retraction, two corrections, and a lot of questions

Franken-paper from U.S. federal contractor heads to the grave

Image via Insomnia Cured Here.

Hindawi journal PPAR Research has pulled a cancer immunology paper after discovering it contained almost no new information.

Instead, it was a Frankenstein-style stitch job, containing sentences ripped from 33 different papers. 18 of those ended up in the citations; for 15 more, the authors didn’t even do them that courtesy. You can see a meticulously color-coded call out here.

Here’s the notice for “A Role for PPARy in the Regulation of Cytokines in Immune Cells and Cancer”: Continue reading Franken-paper from U.S. federal contractor heads to the grave

Heaven still waiting: Publisher pulls book after boy recants on visit to heaven

malarkeyTyndale House says it will be recalling copies of The Boy Who Came Back from Heaven after the boy in question, Alex Malarkey (yes, that’s really his name), said he didn’t make the trip after all.

Malarkey made the claim after having been injured in a car accident when he was 6. The book became a best-seller for Tyndale, which, according to NPR, called it Continue reading Heaven still waiting: Publisher pulls book after boy recants on visit to heaven
