Authors use same images in two studies — one is retracted, the other flagged by journal

After researchers in China included the same images in two papers published online one month apart, one paper has been retracted, and the other flagged with an expression of concern. 

According to the retraction notice in the International Journal of Molecular Medicine (IJMM), the authors intended that the two different papers offered “different research perspectives.”

Meanwhile, the Chinese Medical Journal — which published the same images one month later — has issued an expression of concern (EOC), noting it “should not be considered as a statement regarding the validity of the work.” Both papers describe how cells regulate blood flow to the retina.

Normally, journals choose to retract the most recent paper containing duplicated images, but in this case, the IJMM paper was published online in February 2016, and the Chinese Medical Journal in March.

Here’s the retraction notice: Continue reading Authors use same images in two studies — one is retracted, the other flagged by journal

Prominent researcher in Taiwan loses another paper for image duplication

In November, a vice president at an institution in Taiwan retracted a hotly debated cancer paper from Nature Cell Biology, citing image problems including duplications. Now, the Journal of Biological Chemistry has done the same, again citing image duplications.

There are a few things to note about the latest retraction: One, the last author is again Kuo Min-liang — who holds an appointment at National Taiwan University (NTU), and is also a vice president at Kaohsiung Medical University in Taiwan. Kuo is currently facing allegations that he accepted bribes to add co-authors to his papers; NTU told us it is investigating the latest retraction in the Journal of Biological Chemistry, including Kuo.

The other notable feature of the retraction is the notice itself, which lists a remarkable number of duplicated images. Take a look:

ORI misconduct findings fell in 2016. Why? We ask the director

Kathy Partin

Every year, the U.S. Office of Research Integrity (ORI) issues a series of findings against researchers it has determined committed fraud of some kind. In contrast to many agencies such as the National Science Foundation and around the world, the ORI names the offender, describes the offense, and states the penalty – often a temporary ban on federal funding, for instance.

2016 brought a lot of changes to the agency – it was director Kathy Partin‘s first year, which brought reports of staff unrest (and threats to resign). But there was another notable feature of last year, as we and others have noted – the agency issued only seven findings of misconduct, compared to 14 in 2015 and 11 the year before. (Once a sanction has lifted the finding disappears from the ORI site; here is a count of the agency’s activity from previous years.) We spoke to Partin about this relative lack of action from the agency last year.

“My time and energy were stolen:” Peer reviewer reacts to retraction

Martha Alibali

When a former Stanford psychology researcher lost her fifth paper last year due to unreliable results, one researcher took particular notice: Martha Alibali at the University of Wisconsin-Madison. Why? She had reviewed the 2006 paper, and took to social media to express her dismay at the result of the time and effort she spent on the research. We spoke with Alibali further about her reactions to the news.

Retraction Watch: You reviewed the paper more than 10 years ago. Can you recall what you thought about it? In retrospect, were there any red flags or doubts you had about the findings that you wish you’d caught?

Researcher loses 4th paper flagged by misconduct probe

A researcher in Germany has logged her fourth retraction following an investigation by her former employer that found evidence of scientific misconduct.

The latest retraction for Tina Wenz in the Journal of Applied Physiology mentions the probe at the University of Cologne in Germany, which recommended retracting six of her papers. One had already been retracted by the time the report was released; last month, we reported that two others had been pulled. Now, we’ve come across a fourth.

Here’s the latest retraction notice: Continue reading Researcher loses 4th paper flagged by misconduct probe

Weekend reads: Fake news in science; how not to stress about science; another hilarious sting

The final week of 2016 at Retraction Watch featured the retraction of a high-profile paper on diabetes from Harvard, and the retraction of a JAMA article on whether zinc was useful for the common cold. Here’s what was happening elsewhere: Continue reading Weekend reads: Fake news in science; how not to stress about science; another hilarious sting

The Retraction Watch 2016 year in review — and a sneak peek at our database

It’s been another exciting year for us at Retraction Watch. As always, there has been more to cover than we have time for. At the same time, we’ve expanded our efforts in other media, telling bigger stories and offering more analysis. And we’ve made major progress on our database — more on that in a moment.

A sampling of what happened this year: Continue reading The Retraction Watch 2016 year in review — and a sneak peek at our database

Authors in Spain issue string of corrections

Following a journal probe and questions on PubPeer about their work, authors in Spain have issued four corrections, citing missing raw data for experiments conducted more than 10 years ago.

All papers include the same last two authors, Mireia Duñach at the Autonomous University of Barcelona, and Antonio García de Herreros at the Institut Hospital del Mar d’Investigacions Mèdiques.

Three of the corrections were issued by the Journal of Biological Chemistry, from which the authors retracted three papers earlier this year after a journal investigation concluded they contain reused images, designed to represent different experiments.

Duñach told us the latest corrections are the result of her own initiation:

Cancer researcher in Germany loses multiple papers after misconduct finding

A pathology journal is retracting two papers after an investigation at the last author’s institution in Germany found evidence of scientific misconduct.

The notice for both papers cites an investigation involving Regine Schneider-Stock, who studies cancer biology at the Friedrich Alexander-University Erlangen-Nuremberg (FAU). Meanwhile, another 2005 paper that lists Schneider-Stock as the first author was retracted in October, noting evidence of image manipulation.

The most recent retractions, from the American Journal of Pathology, note that FAU declined to provide the journal with details of its investigation beyond a prepared statement:
