President of Taiwan university to step down amidst investigation

without comments

Pan-Chyr Yang

The president of a top university in Taiwan has announced he will resign from his post at the end of his first term in June.

President Pan-chyr Yang of National Taiwan University (NTU) has opted not to seek a second term as president given two recent investigations — one which concluded last month and one which is ongoing — into allegations of misconduct in papers he co-authored.

Despite being cleared of misconduct in the investigation conducted by his university, Yang felt that the scandal had left a stain on NTU’s reputation, which he hoped to restore by stepping down as president. Here’s more from Focus Taiwan: Read the rest of this entry »

Two more retractions for stem cell researcher appealing her dismissal

with 4 comments

Susana Gonzalez

Susana Gonzalez, a rising star in stem cell research, has had a rough year.

In addition to being fired from her former research institute (which she is now appealing), one of her grants (totaling nearly 2 million Euros) was suspended. Most recently, she has received two new retractions in Nature Communications over figure duplications and missing raw data. By our count, she has a total of three retractions.

Both of the new notices say the papers contained figures duplicated in other papers by Gonzalez, and neither includes Gonzalez among the list of co-authors who agreed to the retraction.

Gonzalez was dismissed from her position at the National Center for Cardiovascular Research (CNIC) in Spain last February over allegations of misconduct. According to the head of basic research at CNIC, Gonzalez is still embroiled in a legal battle with the Center over her dismissal. Vicente Andrés could not go into detail because of the ongoing litigation, but he told us: Read the rest of this entry »

Huh? Cancer paper gets retracted because of its correction

with 2 comments

Here’s a rather odd case: When readers raised issues about some of the images in a 2008 cancer paper, the authors issued a correction last year. But when readers asked additional questions about the corrected images, the authors decided to retract the paper entirely, along with its correction.

Both the original and corrected versions were questioned on PubPeer.

Here’s the retraction notice for the 2008 article “PRIMA-1MET induces mitochondrial apoptosis through activation of caspase-2,” published in Oncogene, which includes a link to the July 2016 correction: Read the rest of this entry »

15-year old paper pulled for image problems

without comments

A group of researchers in France has been forced to retract their 2002 article in the Journal of Virology after learning that the paper was marred by multiple image problems.

The paper, “P0 of Beet Western Yellows Virus Is a Suppressor of Posttranscriptional Gene Silencing,” came from the lab of Veronique Ziegler-Graff, a plant biologist at the University Louis Pasteur, in Strasbourg. The authors attribute some of the image problems to “genuine mounting mistakes,” and have repeated the experiments to confirm the conclusion, as have other labs. However, the researchers couldn’t find all the original data from the 2002 paper.

Although the retraction statement points the finger at the first author, Sebastien Pfeffer, the list of contributors includes Patrice Dunoyer, a frequent collaborator of Olivier Voinnet, a high-profile plant biologist whose work has come under intense scrutiny.

According to the lengthy notice:

Journal flags another paper by diabetes researcher who sued to stop retractions

without comments

It would seem that resorting to legal means to avoid editorial notices doesn’t always work.

We’re coming to that conclusion after seeing yet another notice for Mario Saad, based at the University of Campinas in São Paulo, Brazil. In this case, it’s an expression of concern from the Journal of Endocrinology, on a 2005 paper that lists Saad as the second-to-last author. According to the notice, the journal is concerned the paper contains spliced and duplicated images; although the authors offered to repeat the experiments, the journal considered that potential delay “unacceptable.”

Despite Saad’s legal efforts, he is now up to 11 retractions, along with multiple expressions of concern.

Here’s the full text of the notice (which is paywalled, tsk tsk):

Cancer researcher has dodged accusations for decades (and has a new correction)

with 33 comments

Today isn’t a great day for Carlo Croce, chair of the department of cancer biology and genetics at The Ohio State University (OSU).

The New York Times has a lengthy article detailing the misconduct accusations that have swirled around Croce for years. We’ve covered many, but The Gray Lady obtained documents that show there have been many more.

The story mentions a 2013 letter from Ohio State University to pseudonymous whistleblower Clare Francis (which we reported on in 2014), acknowledging Francis’s allegations against Croce. However, in the letter, an administrator said OSU saw no reason to investigate Croce.

The story didn’t stop there, as the Times reports:

“Hindsight’s a bitch:” Colleagues dissect painful retraction

with 9 comments

Two blog posts are shining additional light on a recent retraction that included some unanswered questions — namely, the identity of the researcher who admitted to manipulating the results.

To recap: Psychological Science recently announced it was retracting a paper about the relationship between the words you use and your mood after a graduate student tampered with the results. But the sole author — William Hart, an assistant professor at the University of Alabama — was not responsible.

The post raised some questions — for instance, who was the graduate student, and if his or her work was so influential to a paper, why was he/she not listed as an author? Hart declined to identify the student, but two new blogs — including one by one of Hart’s collaborators at the University of Alabama — are providing more details.

3rd retraction appears for fired Pfizer breast cancer researcher

without comments

Pfizer has retracted a paper by a former employee who was fired after the company discovered she had been doctoring data.

The retraction, in Molecular Cancer Research, is the third of five papers Pfizer asked to retract, after an investigation discovered they contained duplicated images. The papers have been discussed on PubPeer, which is also mentioned in the latest retraction notice.

As a result of the investigation, Pfizer terminated the employment of Min-Jean Yin, the last author on the newly retracted paper.

According to the notice, Yin and five of her co-authors agreed to the retraction:

Researcher who lost whistleblower lawsuit logs 4 more retractions

with 6 comments

A brain journal has retracted four papers by a researcher due to image duplications that the university uncovered during an investigation into his work.

According to the retraction notice, Wayne State University found that Christian Kreipke had used several images in these articles “to represent different results in grant proposals and/or poster presentations,” and that the data were unreliable. Kreipke now has a total of five retractions, by our count.

As we’ve reported before, Wayne State and Kreipke have been engaged in conflict for several years. In 2012, Kreipke was dismissed from his assistant professor post at Wayne State after the university said it found evidence of research misconduct, according to Courthouse News. Kreipke fired back against the university, filing a whistleblower lawsuit. In it, Kreipke claimed that the institution was “involved in a conspiracy,” according to unsealed court documents, in which it had swindled the U.S. government out of millions in research funding.

A judge dismissed the case in 2014, but the conflict between Kreipke and Wayne State was not over. Read the rest of this entry »

Neuroscientist flags errors in his days-old paper “for the sake of science integrity”

with one comment

Only days after his paper was published online, a neuroscientist has posted a comment on PubMed alerting readers to several duplication errors.

Despite the issues, which the researcher says were introduced into the final manuscript after peer review, he reassured readers that they do not influence the final conclusions in the paper.

On February 9, ten days after the article came online, corresponding author Garret Stuber at the University of North Carolina at Chapel Hill wrote a detailed comment on PubMed Commons, explaining that the “research community” had brought four figure-related errors to his attention. After investigating the concerns, Stuber discovered that the problems emerged after the peer-review process, “while revising the manuscript to comply with Nature Neuroscience’s final formatting guidelines.” In his note, he outlined the specific duplication issues that arose, which he says he plans to detail to the journal in a formal corrigendum letter.

Stuber alerted the scientific community about his PubMed comment via Twitter: Read the rest of this entry »
