Inquiry into duplications reveals “multiple” image problems in tumor study

STEM_17_1.c1.inddA paper on how abnormal stem cells can cause benign bone tumors has been retracted by Cell Stem Cell after an inquiry into image duplications also uncovered “multiple instances of inappropriate western blot image adjustment.”

The first two authors “declined” to sign the retraction, according to the notice.

Besides confirming initial suspicions that images had been duplicated, the editors also found “multiple instances of inappropriate western blot image adjustment, such as uneven compression of images and removal of background elements:”

Golden rice paper pulled after judge rules for journal

home_coverThe American Journal of Clinical Nutrition is retracting a paper that showed genetically engineered rice serves as an effective vitamin A supplement after a Massachusetts judge denied the first author’s motion for an injunction against the publisher.

The journal announced plans to retract the paper last year following allegations that the paper contained ethical mis-steps, such as not getting informed consent from the parents of children eating the rice, and faking ethics approval documents.

Last July, first author Guangwen Tang at Tufts University filed a complaint and motion for preliminary injunction against the journal’s publisher, the American Society for Nutrition, to stop the retraction.

According to the ASN, on July 17, a Massachusetts Superior Court “cleared the way” for the publisher to retract the paper. So they have, as of July 29. Here’s more from the retraction notice:

Voinnet notches second retraction, two more corrections

PNASOlivier Voinnet — a plant researcher who was recently suspended for two years from the Centre national de la recherche scientifique (CNRS) after an investigation by ETH Zurich and CNRS found evidence of misconduct — has issued his second retraction and two more corrections.

PNAS posted the retraction earlier this week for a 2006 article after an inspection of the raw data revealed “errors” in study images. Authors confirmed the issues in some figures and revealed “additional mounting mistakes” in others.

Voinnet has promised to issue retractions and corrections for every study that requires them. These latest notices bring our tally up to nine corrections, two retractions and one Expression of Concern.

Author disputes retraction of pine needle paper published “without the knowledge” of all authors

Screen Shot 2015-06-25 at 1.16.27 PM

The properties of pine needles in northwestern China differ — both inside and out — depending on where on the slope of a mountain they are situated. The properties of a recent paper on this phenomenon have recently changed from “published” to “retracted.”

It appears that some of the authors didn’t realize it had been submitted to The Scientific World Journal. The paper has not been cited, according to Thomson Scientific’s Web of Knowledge.

Here’s the notice:

Retracting duplicated paper “may damage the integrity of the literature,” says plant journal editor

In Vitro Cellular & Developmental Biology - PlantIn Vitro Cellular & Developmental Biology – Plant has flagged a 2004 article that was “accidentally” duplicated from another paper published earlier that year — but did so in the form of a publisher’s erratum, not a retraction.

The editor of the journal justified the decision by arguing that the duplicated paper had been cited “over a dozen times” and was old enough to not warrant a retraction:

Considering that both articles were published over a decade ago and both have been referenced by other papers over a dozen times each, it seems like a retraction of one manuscript may damage the integrity of the literature more than using the erratum to point out the error to future scientists.

The study, “In vitro shoot regeneration from cotyledonary node explants of a multipurpose leguminous tree, Pterocarpus marsupium roxb,” developed a protocol for effectively growing shoots of the Indian Kino tree.

The first version has been cited 21 times and the duplicated version was cited 13 times, according to Thomson Scientific’s Web of Knowledge. Here’s the notice:

Serial plagiarizer notches three retractions

frontCover

The chips are starting to fall from investigations into the works of Mustapha Marrouchi, a former English professor at the University of Nevada Las Vegas (UNLV) — he’s lost three papers from the journal College Literature.

Things began publicly unraveling for Marrouchi last year when an investigation by the Chronicle of Higher Education found lifted material in his books, essays, and peer-reviewed papers. (It’s worth scanning the comparisons to text from Salman Rushdie, John Updike, and other authors.)

Meanwhile, an investigation by the UNLV found that 23 out of 26 of his papers published between 2008 and 2013 contained instances of plagiarism. He was later fired.

Now, the fallout continues, with the retraction of three works published in 2010 and 2011 in College Literature. All papers were for plagiarism uncovered as the result of a UNLV investigation (presumably, the same one).

The retracted papers are: Continue reading Serial plagiarizer notches three retractions

“Falsified” data shelve two more drug studies from discredited U Colorado student

The authors of a pair of papers in Molecular Pharmaceutics are retracting them following an investigation at the University of Colorado Denver, which found a graduate student had faked data.

Rajendra Kadam was a prominent member of the Research lab of Uday B. Kompella, until the investigation revealed earlier this year that he had “falsified” data from a liquid chromatography-mass spectroscopy (LC-MS) machine for years.

So far, we’ve found four retractions (including the latest two) and one expression of concern for Kadam. There may be more on the way: Continue reading “Falsified” data shelve two more drug studies from discredited U Colorado student

Oregon grad student admits to faking data in four neuroscience papers

oriweb_logoA graduate student at the University of Oregon in Eugene has admitted to faking data that appeared in four published papers in the field of visual working memory, according to the Office of Research Integrity.

David Anderson’s supervisor at the time was Edward Awh, who has since moved to the University of Chicago.

Anderson told Retraction Watch that the misconduct stemmed from “an error in judgment”:

UPitt investigation brings total retraction count to four for pair of cancer researchers

Journal of Biological Chemistry1An official inquiry by the University of Pittsburgh has led to two more retractions for a pair of cancer researchers, Tong Wu and Chang Han. By our count, the pair now have four retractions under their belt, all the result of the university investigation.

The Journal of Biological Chemistry published the notices earlier this month, after it was discovered the papers contained cropped panels, among other issues. Importantly, the two papers appear to even have shared some data.

One 2006 paper, “Modulation of Stat3 Activation by the Cytosolic Phospholipase A2α and Cyclooxygenase-2-controlled Prostaglandin E2 Signaling Pathway,” investigated the molecular actors in cancer growth, such as overexpression of cyclooxygenase-2 (COX-2). It has been cited 34 times, according to Thomson Scientific’s Web of Knowledge. Here’s the notice:
