Researcher at Japan stem cell institute falsified nearly all images in 2017 paper

Shinya Yamanaka

An investigation by Kyoto University in Japan has found a researcher guilty of falsifying all but one of the figures in a 2017 stem cell paper.

Yesterday, Kyoto University announced that the paper’s first author, Kohei Yamamizu, had fabricated and falsified data in the Stem Cell Reports paper. According to the investigation report, none of the other authors were involved in the data manipulation.

Yamamizu works at the Center for iPS cell Research and Application (CiRA) at Kyoto University, directed by Shinya Yamanaka, a Nobel Prize winner for his pioneering work in stem cell biology.

A spokesperson for the journal told us that the authors disclosed the problems last week and Stem Cell Reports will be retracting the paper, published last February.

In the university’s official statement, Yamanaka said: Continue reading Researcher at Japan stem cell institute falsified nearly all images in 2017 paper

University in Japan finds cancer researcher guilty of misconduct

A university in Japan has found a former professor guilty of falsifying and altering images in four published papers, including a 2014 paper about stem cells.

On Dec. 15, Tottori University announced the results of its misconduct investigation, in which the cancer researcher, Norimasa Miura, confessed to altering images in the four papers.

According to the report, which we translated, Miura resigned as associate professor at Tottori University a month before the investigation concluded in October of this year. Miura had already stopped receiving grant and research funding in May, one month into the six-month investigation. Continue reading University in Japan finds cancer researcher guilty of misconduct

Caught Our Notice: After ORI flags a paper by former grad student, university flags another

Title: The L3MBTL3 Methyl-Lysine Reader Domain Functions As a Dimer

What Caught Our Attention: Six months ago, the U.S. Office of Research Integrity (ORI) determined that former graduate student Brandi Baughman had doctored 11 figures in a PLOS ONE article, which was retracted shortly after.  The PLOS ONE paper listed two affiliations for Baughman — the National Institute of Environmental Health Sciences and the University of North Carolina, Chapel Hill (UNC); now UNC has triggered a second retraction of a paper co-authored by Baughman, also due to research misconduct. Although the ORI notice makes no mention of this additional paper, the agency recently took a “targeted approach” by not issuing comprehensive findings of misconduct for one researcher, in order to conserve resources. Of course, sometimes universities make findings that don’t meet the ORI’s bar, too. Continue reading Caught Our Notice: After ORI flags a paper by former grad student, university flags another

Another retraction to appear for Cornell food scientist Brian Wansink

Brian Wansink

The new year will bring a sixth retraction for food scientist Brian Wansink, whose work has been under fire for all of 2017.

Although the notice has not yet been released, the journal Appetite plans to retract a 2003 paper about the different forces that motivate people to try new foods (referring, in this specific context, to soy).

It’s unclear why “Profiling taste-motivated segments” is being retracted (we asked the journal, but haven’t immediately heard back); some potential issues were flagged in March by Nick Brown, a PhD student who has devoted hundreds of hours to analyzing Wansink’s work (and forwarded us the email from Appetite confirming the upcoming retraction).

For instance, Brown alleged the article contains duplicated material, and similarities to the results from another 2002 paper that also measured soy consumption. After analyzing those two papers and a 2004 paper (also about eating soy), Brown concluded:

University finds falsified data in PNAS gene therapy paper, authors retract

A university investigation has found falsified data in a 2011 paper about the side effects of a virus commonly used in gene therapy.

The authors are retracting the paper, but one co-author told Retraction Watch they stand by their main conclusions. According to Roland Herzog, a professor at the University of Florida (UF) College of Medicine and a co-author of the paper, the falsified data were related to a minor part of the paper.

The paper, “Activation of the NF-κB pathway by adeno-associated virus (AAV) vectors and its implications in immune response and gene therapy,” was published in the Proceedings of the National Academy of Sciences (PNAS) in March 2011. All authors were affiliated with UF at the time; the handling editor, Kenneth Berns, is an emeritus professor at UF. The paper has been cited 50 times, according to Clarivate Analytics’ Web of Science. Continue reading University finds falsified data in PNAS gene therapy paper, authors retract

Author of controversial Science fish-microplastics paper committed “intentional” misconduct, says Uppsala

An investigation at Uppsala University has found the authors of a retracted Science paper — which explored the threat of human pollution on fish — guilty of misconduct.  

The decision, published yesterday, states that both authors—Peter Eklöv and Oona Lönnstedt—“violated the regulations on ethical approval for animal experimentation,” and Lönnstedt, the paper’s corresponding author, “fabricated the results.”

Eklöv told us: Continue reading Author of controversial Science fish-microplastics paper committed “intentional” misconduct, says Uppsala

University investigation finds misconduct by bone researcher with 23 retractions

Hirosaki University

As a bone researcher continues to accrue retractions, an investigation at his former university has found misconduct in more than a dozen papers.

On Nov. 15, Japan’s Hirosaki University announced it had identified fabrication and authorship issues in 13 papers by Yoshihiro Sato, and plagiarism in another.

Sato, a professor at Hirosaki University Medical School from 2000 to 2003, died in January. He was last affiliated with Mitate Hospital. Multiple retractions in recent months have pushed Sato higher up our leaderboard; by our count, he now has 23 retractions and the university said there are likely more to come.

Carlo Croce, facing misconduct allegations, accuses former colleague of misconduct

Carlo Croce

Carlo Croce, a cancer researcher who has faced numerous research misconduct allegations, recently accused a former lab member of misconduct. Although an institutional probe did not support that allegation, Croce’s efforts have led to a retraction.

In November 2015, Croce and another cancer researcher at Ohio State University (OSU), Ramiro Garzon, contacted PLOS ONE, alleging that the paper’s corresponding author, Stefan Costinean, published data without their knowledge or permission and without “accurately acknowledging their contributions to the research.” Although the PLOS ONE paper mentioned Croce’s and Garzon’s contributions in the acknowledgements section, the two were not included as co-authors. We have obtained a copy of the report describing OSU’s preliminary probe; it did not find evidence of misconduct, but recommended the paper be retracted for using data without permission. Although Costinean disagreed, the journal has since retracted the paper.

Croce has been on the other side of this process: Seven of his papers have been retracted for issues including manipulation and duplication. After a New York Times article, published in March, explored misconduct allegations against Croce, OSU said the university is “instituting an independent external review.” Croce is currently suing the New York Times, alleging that the newspaper defamed him in the story.

Title: Unravelling the influence of mild traumatic brain injury (MTBI) on cognitive-linguistic processing: A comparative group analysis

What Caught our Attention: RW readers might already be familiar with Caroline Barwood and Bruce Murdoch, two researchers from Australia who had the rare distinction of being criminally charged for research misconduct. Both Barwood and Murdoch received suspended sentences after being found guilty of multiple counts of fraud. In September 2014, University of Queensland announced that: Continue reading Caught Our Notice: Ethics, data concerns prompt another retraction for convicted researchers

Researcher dismissed from university for suspected misconduct denies responsibility

Masashi Emoto

A university in Japan dismissed a researcher earlier this month after a probe uncovered evidence of image falsification in several of his papers.

The immunology researcher, Masashi Emoto, denied any wrongdoing. He has said that the experiments in question were performed by another researcher and “he was not responsible” for the falsification.

In 2013, Emoto filed a suit against Gunma University, in which he claimed another researcher possessed the raw data for the experiments in question. Emoto requested those documents be returned to him. However, the court determined that Emoto possessed the raw data.

According to the report — released by Gunma University on October 11 — without the raw data, the university could not prove Emoto committed the misconduct. However, the university determined that, as the corresponding author on the four papers, Emoto was responsible for the work.

According to our English version of the report, which we translated from Japanese using One Hour Translation, the committee concluded: Continue reading Researcher dismissed from university for suspected misconduct denies responsibility
