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

Penn State postdoc faked data in cancer manuscript

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:

Head of major diagnostic lab in Canada steps down amid investigation

AJPA_v185_i7_COVER.inddA prominent endocrinologist pathologist has resigned from running the largest hospital diagnostic laboratory in Canada following an investigation that has uncovered evidence of falsified data in two papers, Retraction Watch has learned.

Sylvia Asa was the Program Medical Director of the Laboratory Medicine Program at the University Health Network, affiliated with the University of Toronto, until this past spring when she stepped down, according to UHN spokesperson Gillian Howard:

What do you do after painful retractions? Q&A with Pamela Ronald and Benjamin Schwessinger

2013 was a rough year for biologist Pamela Ronald. After discovering the protein that appears to trigger rice’s immune system to fend off a common bacterial disease – suggesting a new way to engineer disease-resistant crops – she and her team had to retract two papers in 2013 after they were unable to replicate their findings. The culprits: a mislabeled bacterial strain and a highly variable assay. However, the care and transparency she exhibited earned her a “doing the right thing” nod from us at the time.

After many months spent understanding what went wrong and redoing the experiments correctly, today Ronald and her team release another paper in Science Advances that reveals the protein they thought they had identified in 2013.

Ronald and co-first author Benjamin Schwessinger (who recently became an independent research fellow at the Australian National University in Canberra) spoke to us about the experience of recovering from the retractions and finally getting it right. The conversation has been edited for brevity and clarity.

-What did you do differently this time so you didn’t repeat the same mistakes?

“Part of a paper that had already appeared”: Materials paper pulled for plagiarism

1-s2.0-S1387181115X00035-cov150hMicroporous and Mesoporous Materials has retracted a 2015 paper after it was discovered the authors “have plagiarized part of a paper that had already appeared.”

The paper, “Ionic liquid assisted synthesis of flexible and super-hydrophobic porous gels,” described the synthesis of a form of flexible aerogels “through a facile one-pot preparation,” according to the abstract. According to Thomson Scientific’s Web of Knowledge it has been cited zero times.

Here is the retraction note, in full:

Author’s ties to NFL lead to correction for review that cast doubt on brain risk from sports

PLOS ONE

A review paper that suggested the degenerative brain disease that’s striking former football players may not be tied to contact sports has been corrected to reveal the first author spent decades working for the National Football League.

The correction appears in a review in PLOS ONE about chronic traumatic encephalopathy – the degenerative brain disease that was the basis of a $765 million settlement for former NFL players, along with a number of similar lawsuits. It fixes incorrect statements and adds conflicts of interest, including those with with first author Joseph Maroon, who spent more than 30 years working with the NFL and seven for the wrestling group the WWE.

It appears as if all the original paper declared was that Maroon was an “unpaid consultant” to the Pittsburgh Steelers. But apparently there was a lot more to it, according to the notice:
