Researchers plagiarized chapter of doctoral thesis in mol bio paper

mol cell biochemA journal has pulled a paper about the molecular details of different types of adipose tissues after learning the researchers had plagiarized much of a Ph.D. thesis.

The researchers copied from former Ph.D. student Bettina Meissburger’s doctoral thesis in a 2013 paper in Molecular and Cellular Biochemistry. The retraction note for “Adipose stromal-vascular fraction-derived paracrine factors regulate adipogenesis” provides the name of Meissburger’s thesis: Continue reading Researchers plagiarized chapter of doctoral thesis in mol bio paper

JACS imaging paper “under editorial review”

Screen Shot 2016-01-04 at 2.02.27 PM

The Journal of the American Chemical Society has issued an expression of concern over “the presentation of results” in a 2014 paper about a new probe for use in imaging.

We haven’t heard back from the journal nor the authors of the paper, so there’s not much we can officially say about what the journal is investigating.

Here’s the text from the expression of concern:

2014 ORI finding results in retraction of cancer paper with manipulated images

Mol Can TherA paper flagged in an Office of Research Integrity notice more than one year ago has finally been retracted. According to the notice, the paper includes images manipulated by author H. Rosie Xing, a former University of Chicago cancer researcher.

The main conclusions of the paper are affected by the ORI finding, according to the retraction note from Molecular Cancer Therapeutics. But otherwise, the note contains information that was available in the ORI finding, published in December 2014.

“Pharmacologic Inactivation of Kinase Suppressor of Ras1 Sensitizes Epidermal Growth Factor Receptor and Oncogenic Ras-Dependent Tumors to Ionizing Radiation Treatment” has been cited seven times, according to Thomson Scientific’s Web of Knowledge — twice since the ORI finding came out.

The retraction note explains which images were affected by the manipulation:

Investigation prompts 5th retraction for cancer researcher for “unresolvable concerns”

3.coverAn investigation at the University of New South Wales in Australia has led to a fifth retraction for a cancer researcher long accused of misconduct, due to “unresolvable concerns” with some images.

As we reported in December, UNSW cleared Levon Khachigian of misconduct, concluding that his previous issues stemmed from “genuine error or honest oversight.” Now, Circulation Research is retracting one of his papers after an investigation commissioned by UNSW was unable to find electronic records for two similar images from a 2009 paper, nor records of the images in original lab books.

Again, the retraction note affirms that this is not a sign of misconduct:

UNSW has not attributed any instance of research misconduct or responsibility for the unavailability of the original data to Professor Khachigian or to any of the authors of the publication.

Here’s the retraction note in full for “Angiotensin II-Inducible Smooth Muscle Cell Apoptosis Involves the Angiotensin II Type 2 Receptor, GATA-6 Activation, and FasL-Fas Engagement:” Continue reading Investigation prompts 5th retraction for cancer researcher for “unresolvable concerns”

Another case of plagiarism in papers published only months apart

pageHeaderTitleImageRemember when we recently found PLOS ONE had published two papers with “substantial overlap” from two different groups, that were edited around the same time? Well, we have discovered another similarly perplexing case of plagiarism in two studies published only months apart. But in this instance, we have a possible explanation for how two groups of authors from different institutions could report a similar experiment and data, and even use some of the same text.

It also concerns a paper focusing on cancer biology — in this case, it’s a 2014 paper retracted by Clinical and Investigative Medicine after editors learned that it contained many similarities to a study published only a handful of months before in Tumour Biology.

According to an email from an author on the retracted paper to the editor, Continue reading Another case of plagiarism in papers published only months apart

“There was no effort to commit fraud,” says EMBO awardee under investigation

A recent recipient of an early career award now under investigation by granting agency EMBO told us today that last week’s retraction in Nature Genetics stemmed solely from an “embarrassing error,” and she hopes to republish the data in a new paper.

Last week was rough for Sonia Melo: Nature Genetics retracted one of her papers, and the European Molecular Biology Organization (EMBO) announced it was investigating the papers that formed the basis of her application. The retraction was of “A TARBP2 mutation in human cancer impairs microRNA processing and DICER1 function,” which has been cited 235 times, according to Thomson Scientific’s Web of Knowledge.

Melo’s Installation Grant from EMBO was announced in December, and consists of 50,000 Euros annually for three to five years. She is currently based at the University of Porto, in Portugal.

Melo contacted us today to defend her record: Continue reading “There was no effort to commit fraud,” says EMBO awardee under investigation

You’ve been dupe’d: Data so nice, you see them twice

j repro infertLast Friday we resurrected a previous feature of Retraction Watch, compiling five retractions that appeared to be simple acts of duplication.

This week, we spotlight another five unrelated retractions which, as we said last week, cover duplications in which the same – or some of the same – authors published the same – or some of the same – information in two different papers.

Most duplications are straightforward — all authors simply send the same or similar study to two or more journals, a violation of most journals’ terms of use.  For instance: Continue reading You’ve been dupe’d: Data so nice, you see them twice

EMBO takes back Voinnet’s award, investigates other awardee who just lost a Nature Genetics paper

Screen Shot 2016-01-28 at 11.41.20 AMEMBO has taken back an award given to beleaguered plant biologist Olivier Voinnet in 2009, and is investigating a recent grantee who had a paper retracted from Nature Genetics yesterday.

The European Molecular Biology Organization (EMBO) “promotes excellence in the life sciences” in Europe, in part by awarding prizes to promising young scientists. Voinnet and Sonia Melo earned their awards by exhibiting potential as young scientists studying genetics — of plants and cancer, respectively — but now EMBO is skeptical of the papers that formed the basis of their applications.

Melo’s Installation Grant from EMBO was announced just last month, and consists of 50,000 Euros annually for three to five years. She is currently based at the University of Porto, in Portugal.

Voinnet’s problems are well-documented on this blog — 21 corrections, seven retractions, and two investigations. Earlier this week, we reported that the Swiss National Science Foundation had cut off Voinnet’s funding, and banned him for three years.

Authorship dispute fells membrane paper

no spine minimum. full size. Editor: Barbara Sydow JEM: Clay RTP: Cynthia Porath jpcbfk

A membrane paper has been retracted only two months after publication in the Journal of Physical Chemistry B because of an authorship dispute.

The paper, “Magnetic Interaction of Transition Ion Salts with Spin Labeled Lipid Membranes: Interplay of Anion-Specific Adsorption, Electrostatics, and Membrane Fluidity,” has not been cited, according to Thomson Scientific’s Web of Knowledge. (It appears to be taken down entirely, but it looks like you can read its abstract here.)

Here’s the entire — very short — note:

Seralini paper claiming GMO toxicity disappears after journal domain expires

SJASA paper claiming genetically modified corn may be toxic over long periods has disappeared one day after it was presented at a press conference, after the journal’s domain name expired.

The paper, co-authored by Gilles Seralini — who has published controversial research showing harms of GM food — appeared in the Scholarly Journal of Agricultural Sciences (SJAS). On Tuesday, the Committee for Independent Research and Information on Genetic Engineering (Criigen) scheduled a press conference about the findings, noting the finding presented

new scientific data on Bt toxins and a thorough study of the records show that this GMO Bt maize is most probably toxic over the long term.

But on Wednesday January 27, the journal’s domain name expired. This isn’t a retraction per se, but a disappearance. Now, any link to the study “Pathology reports on the first cows fed with Bt176 maize (1997–2002)” goes to this page, which says in the bottom right corner: Continue reading Seralini paper claiming GMO toxicity disappears after journal domain expires
