There’s “no evidence” research was conducted at all in retracted cancer paper

cov200h (1)To one reader of a paper on a nerve cancer, the researchers, based at a hospital in China, seemed to have found a very large number of cases of a rare cancer to study. That observation triggered an investigation into the paper that led to its retraction — and the concern that the authors in the paper never did the research at all.

The authors say they recruited 156 patients who had a particular kind of cancer that affects the tissue around nerves, known as malignant peripheral nerve sheath tumors. For context on how rare that is: Other researchers found a mere 1,182 new cases over a nearly four-decade period in the U.S. The study, according to the methods section of the paper, was supposedly done with patients who had a specific type of the disease, and who were

consecutively recruited from Wuhan Union Hospital, Huazhong University of Science and Technology in Wuhan (Hubei, China) between July 2000 and November 2012

According to the retraction note for “Common genetic variants in the microRNA biogenesis pathway are associated with malignant peripheral nerve sheath tumor risk in a Chinese population,” the hospital where the work was done never treated all of those patients:

Dutch investigation of researcher violated rules of “fair play”: Ombudsman

Pankaj Dhonukshe

The National Ombudsman of The Netherlands has criticized some aspects of an investigation by Utrecht University that found a researcher had committed “a violation of academic integrity.”

Specifically, the Ombudsman found the investigation — which we covered last year — did not adequately involve the affected researcher, Pankaj Dhonukshe, and therefore violated rules of “fair play.” Dhonukshe expressed relief in a statement he emailed to us about the ruling: Continue reading Dutch investigation of researcher violated rules of “fair play”: Ombudsman

Investigation ends in 6th retraction for Voinnet

PLOS PathogensA sixth paper co-authored by plant researcher Olivier Voinnet has been retracted by PLOS Pathogens “following an investigation into concerns.”

The investigation found “several band duplications” in one figure provided by fifth author, Patrice Dunoyer, who took it from “the Master thesis of a former student working under his supervision, without the prior consultation or consent of this student,” according to the notice. There was also an incorrect “loading control” in another figure, attributed to first author Raphael Sansregret and last author Kamal Bouarab. 

Voinnet and Bouarab, the study’s corresponding authors, took full responsibility for “the publication of this erroneous paper.”

Although investigators found that the raw data in the duplicated figure backed up its conclusions, “given the nature and extent of data manipulation,” the authors asked the journal to retract the paper .

Danish neuroscientist sentenced by court for lying about faked experiments

court caseIn a rare development, neuroscientist Milena Penkowa has been sentenced by a Danish court for faking data.

The ruling, from the Copenhagen City Court, resulted from Penkowa’s publication of her 2003 thesis describing experiments that she never carried out. The court “placed weight” on the fact that she didn’t just commit fraud, but “systematically supplied false information” to avoid being caught, according to the court’s notice.

The sentence is nine months of “conditional imprisonment,” according to our translation; The University Post, a newspaper affiliated with the University of Copenhagen, calls it a “nine month suspended sentence with a two years probation.”

Here’s the full summary of the new ruling, from the Copenhagen City Court (translated from Danish by One Hour Translation):

NIH rescinds grant to Texas eye researcher

banner-nihlogoA scientist who uses imaging to study the eye and brain has lost a major grant from the U.S. National Institutes of Health.

In June, the NIH revised the award for Timothy Duong at the University of Texas Health Science Center at San Antonio from $332,500 per year to $0, and included this statement: Continue reading NIH rescinds grant to Texas eye researcher

4th ORI-flagged paper by Oregon student is retracted

home_cover (2)The last of four papers containing data falsified by University of Oregon neuroscience student David Anderson has been retracted.

When the Office of Research Integrity report flagging the papers came out in July, Anderson told us he “made an error in judgment,” and took “full responsibility” for the misconduct.

The newly retracted paper, “A common discrete resource for visual working memory and visual search,” published in Psychological Science, has been cited 28 times, according to Thomson Scientific’s Web of Knowledge. According to the abstract, it demonstrates a possible link between working memory and the ability to “rapidly identify targets hidden among distractors.”

But according to the retraction note, Anderson produced “results that conformed to predictions” by “removing outlier values and replacing outliers with mean values”  in some of the data.

Here’s the retraction note in full:

Mirror image in plant study flagged on PubPeer grows into retraction

djs_mpmi_28_9_cover-online.inddA 2010 paper on plant fungus has been retracted after a comment on PubPeer revealed that a study image had been flipped over and reused to represent two different treatments.

In May, a commenter pointed out the plants in Figure 2a of the paper in the journal Molecular Plant-Microbe Interactions “look remarkably similar.” A commenter writing under the name of corresponding author, Yukio Tosa at Kobe University in Japan, posted a response two days later agreeing with the assessment and stating that the paper should be retracted.

The notice reads: Continue reading Mirror image in plant study flagged on PubPeer grows into retraction

Biologist banned by second publisher

TF

Plant researcher Jaime A. Teixeira da Silva has been banned from submitting papers to any journals published by Taylor & Francis. The reason: “continuing challenges” to their procedures and the use of “inflammatory language.”

This is the second time Teixeira da Silva has been banned by a publisher —  last year Elsevier journal Scientia Horticulturae told him that they refused to review his papers following “personal attacks and threats.”

Apparently, Taylor & Francis has too become frustrated with Teixeira da Silva’s communication strategy. Anthony Trioli, from Taylor & Francis, told Teixeira da Silva in an email (to which Teixeira da Silva copied us on his reply) that they would no longer accept his papers:

PLOS Genetics updates flagged paper with expression of concern

Screen Shot 2015-09-15 at 2.15.29 PM

PLOS Genetics has upgraded a notice on a paper to an expression of concern, raising the count for author chemist Ariel Fernandez to one retracted paper, and three expressions of concern.

The journal published “Protein Under-Wrapping Causes Dosage Sensitivity and Decreases Gene Duplicability” in 2008. In 2013, Fernandez corrected it, claiming that the work was not actually funded by the U.S. National Institutes of Health, as the original paper had said. The paper has been cited 33 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the expression of concern in full, which was published on September 14:

Author appeals retraction after co-authors dispute Nature Comm paper

nature comm

Two weeks after Nature Communications published a paper on asymmetric cell division in July, it posted a retraction notice saying the paper was submitted “without the knowledge or consent” of all but the corresponding author.

The following day the journal “amended” the retraction note to include the initials of the corresponding author, Aicha Metchat, then based at European Molecular Biology Laboratory in Heidelberg, Germany.

The final notice for “An actin-dependent spindle position checkpoint ensures the asymmetric division in mouse oocytes” reads:
