Fraud by bone researcher takes down two meta-analyses, a clinical trial, and review

The troubles continue for a bone researcher, who’s lost multiple papers in recent months due to problems ranging from data issues to including authors without their consent.

Now, journals have retracted two more papers by Yoshihiro Sato. And in a sign of the downstream effects that fraud can have, another journal has retracted two meta-analyses by other authors that cited his work.

Earlier this month, the journal Current Medical Research and Opinion retracted the two meta-analyses because they were based on recently retracted papers by Sato, affiliated with Mitate Hospital. The two new retractions of Sato’s papers are a review and a randomized controlled trial.

Sato was not an author on the meta-analyses published in 2008 and 2011; he was, however, first and lead author on all the retracted papers referenced in the notices. The notices state that the trio of authors on the meta-analyses:

Prominent physicist loses four more papers for duplication

A leading physicist in India has lost four more papers for duplication, after colleagues lodged a complaint against him.

According to the most recent retraction notices, issued by Applied Surface Science, the four papers duplicated several figures and portions of text from the authors’ previous works. Although the notices do not single out a responsible party, last year the Mumbai Mirror reported that first and corresponding Naba K. Sahoo had been accused of duplication by colleagues at the Bhabha Atomic Research Centre (BARC), part of Indian government’s Department of Atomic Energy.

(In a bizarre twist, Sahoo also made the news recently for getting into a fist fight with another BARC scientist.)

Sahoo received two retractions last year for duplication, sometimes inelegantly referred to as “self-plagiarism.” All six of his retractions affect papers published by Applied Surface Science between 2005 and 2007.

The first retraction notice explains that a 2006 paper lifted portions of text from an earlier paper by Sahoo: Continue reading Prominent physicist loses four more papers for duplication

Retraction notice cites misconduct investigation into endowed chair’s work; he threatens to sue

Mark Jackson

A researcher has threatened to sue publisher Taylor & Francis for mentioning a misconduct investigation into his work in a retraction notice.

According to the notice, the publisher retracted a 2008 paper and a book chapter after learning about a misconduct investigation into the work of Mark Jackson, a department head and endowed chair, respectively, at universities in Kansas.

Unfortunately, we don’t know much about the nature of the misconduct investigation; Jackson told us he initiated the retractions after raising concerns his colleagues had violated intellectual property. He has since told the publisher he would take legal action if it didn’t remove the phrase noting that the retractions stem from a misconduct investigation into his work from the notice.

Here’s the notice, issued by Materials Science and Technology:

Fired Pfizer cancer researcher loses final two of five papers pegged for retraction

PLOS ONE has retracted the last of five papers by a former employee of Pfizer, who the company fired after determining she had duplicated data.

After its investigation, Pfizer asked journals to retract five papers co-authored by Min-Jean Yin. Last week, PLOS ONE retracted the final two remaining papers. Both notices cite image duplications; Yin contacted the journal about one paper, but did not comment on the other retraction.

Here’s the notice for “miR-221 Promotes Tumorigenesis in Human Triple Negative Breast Cancer Cells:”

Weekend reads: Death of a cancer lab; women economists’ papers are more readable; self-correction grows

The week at Retraction Watch featured a study of why researchers commit misconduct, and the story of former Northwestern scientist who sued the university for defamation. Here’s what was happening elsewhere: Continue reading Weekend reads: Death of a cancer lab; women economists’ papers are more readable; self-correction grows

As third retraction for prominent physicist appears, university still won’t acknowledge investigation

Despite a university’s attempts to avoid discussing a misconduct investigation involving one of its former (and prominent) researchers, we keep reading more about it.

In the third retraction this year for physicist Dmitri Lapotko, the journal mentions a misconduct investigation at Rice University, which concluded the data had been falsified. Trouble is, whenever we’ve tried to talk to Rice about that investigation, they won’t even confirm it took place.

Here’s the retraction notice for “Transient Photothermal Spectra of Plasmonic Nanobubbles,” published by Langmuir:

Why do researchers commit misconduct? A new preprint offers some clues

Daniele Fanelli

“Why Do Scientists Fabricate And Falsify Data?” That’s the start of the title of a new preprint posted on bioRxiv this week by researchers whose names Retraction Watch readers will likely find familiar. Daniele Fanelli, Rodrigo Costas, Ferric Fang (a member of the board of directors of our parent non-profit organization), Arturo Casadevall, and Elisabeth Bik have all studied misconduct, retractions, and bias. In the new preprint, they used a set of papers from PLOS ONE shown in earlier research to have included manipulated images to test what factors were linked to such misconduct. The results confirmed some earlier work, but also provided some evidence contradicting previous findings. We spoke to Fanelli by email.

Retraction Watch (RW): This paper builds on a previous study by three of your co-authors, on the rate of inappropriate image manipulation in the literature. Can you explain how it took advantage of those findings, and why that was an important data set? Continue reading Why do researchers commit misconduct? A new preprint offers some clues

Another retraction for student who confessed to cooking data

A journal has retracted another paper by a graduate student formerly based at Albert Einstein College of Medicine in New York, after she spontaneously confessed to fabricating data.

As we reported in April 2016, principal investigator Florence Marlow alerted the institution’s Office of Research Integrity and two journals about Meredyth Forbes’s admission, prompting an investigation into the extent of the data manipulation.

Three papers were affected: In January 2016, Development flagged one paper with an expression of concern, alerting readers to the potential issues with the data while the authors and Research Integrity Office investigated the scope of the problem. In April 2016, another paper was retracted by Cell Reports; the third, also published in Development, received a correction.

Last month, the authors and Development decided to retract the paper that had been flagged with an EOC (which appears on page 2 here).  Continue reading Another retraction for student who confessed to cooking data

Three figures in blood pressure paper were manipulated, says journal

A pharmacology journal has retracted a 2011 paper after concluding images in three figures had been manipulated.

According to the British Journal of Pharmacology, four of the five authors claim they played no role in the manipulation. There is no comment from the remaining author, first author Ian Morecroft, a research associate at the University of Glasgow.

Here’s more from the notice, which says an investigation at the University of Glasgow is ongoing:

Author surprised when publisher pulls three of her papers

A researcher is strongly objecting to a publisher’s decision to retract three of her papers from two computing journals without informing her first.

The reason: Self-plagiarism, which the author said stemmed from her PhD student using similar descriptions for the background sections of the papers. She argued that if the reviewers had flagged the duplication, she would have been happy to revise the papers before publication. A representative of the publisher, Springer, told us the overlap was extensive enough for the journal to determine the papers should be retracted.

We spoke with Sameem Abdul Kareem from the Department Of Artificial Intelligence at the University of Malaya in Malaysia, last author on all three papers, which she co-authored with her former PhD student Haitham Badi (also referred to as Haitham Hasan in several papers). She explained how the duplication occurred:
