Cancer paper retracted after author discovers signs of data manipulation

with one comment

A molecular biology journal has retracted a 2017 cancer paper only two months after it appeared online, after the corresponding author notified the journal about possible data manipulation.

According to the notice, Chunsun Fan, from Qidong Liver Cancer Institute & Qidong People’s Hospital in China, requested the retraction after finding “signs of data manipulation” in the paper that was published online in April. The journal, FEBS Letters, acted quickly, publishing a retraction earlier this month.

“Searching our souls”: Authors retract paper after researcher admits to fabricating data

without comments

Researchers at a prominent Japanese university have retracted a 2016 paper in a chemistry journal after the first author admitted to scientific misconduct.

According to the notice, Kyushu University investigated and verified that the first author had committed scientific misconduct.

We requested a copy of the misconduct report, which revealed that the researcher, Prasenjit Mahato, a postdoctoral fellow at Kyushu University who is no longer affiliated with the university, “admitted to falsifying research” in two papers on which he was first author: a highly cited 2015 paper in Nature Materials, which was retracted in 2016, as well as the 2016 paper in Journal of the American Chemical Society (JACS), retracted earlier this month. The university investigated and confirmed misconduct in both papers.

We covered the Nature Materials retraction last year, but at the time, the paper’s corresponding author, Nobuo Kimizuka, only told us that the “matter has been under investigation by the formal investigation panel of our University.”

According to the five-page misconduct report — which we translated from Japanese using One Hour Translation and is also available in Japanese on the university’s website — in July 2016, a member of the lab (“Faculty Member B”) began to suspect a problem after he reviewed the data with Mahato (“the defendant”): Read the rest of this entry »

12 years after researcher found guilty of misconduct, journal retracts paper

with 4 comments

In 2005, the U.S. Office of Research Integrity found an obesity researcher had engaged in scientific misconduct.

More specifically, the ORI report revealed that Eric Poehlman, then based at the University of Vermont, had “falsified and fabricated” data in 10 papers. The 2005 report asked that the journals issue retractions or corrections to the papers. By 2006, six of those papers were retracted (1, 2, 3, 4, 5, 6). In 2006, a judge sentenced Poehlman to one year and one day in prison for falsifying research data.

In 2015, we explored how long it takes a journal to retract a paper. We found that four of the 10 papers had still not been retracted — one appeared to be missing from Medline, another had received a correction (as the ORI report requested), and two had not been retracted or corrected (1, 2).

Until now. Read the rest of this entry »

NIH researcher doctored 11 figures in 2016 paper, says ORI

with 3 comments

A former Research Training Awardee at the National Institutes of Health “falsified and/or fabricated data” in 11 figures in a 2016 paper, according to the U.S. Office of Research Integrity.

This is the first finding of misconduct issued this year by the ORI.

According to the finding, published in the Federal Register, Brandi M. Baughman — formerly at the National Institute of Environmental and Health Sciences (NIEHS) — tweaked data and text in a PLOS ONE paper about screening for compounds that inhibit an enzyme known as inositol phosphate kinase. According to the notice, however, some of those experiments didn’t proceed as described:

Former prof fudged dozens of images, says university

with 16 comments

On Dec. 2, 2013, Alison Lakin, the research integrity officer at the University of Colorado Denver, received a concerning email.

The emailer was alleging several problems in a 2012 paper in the Journal of Clinical Investigation, co-authored by one of its high-profile faculty members. Lakin discussed the allegations with some administrators and agreed they had merit; Lakin sequestered an author’s laptop and other materials. Over the next few months, the university learned of additional allegations affecting other papers — and discovered even more serious problems in the JCI paper. Namely, the first author had inserted changes to 21 figures in the paper after submitting it, without alerting the other authors, journal, or reviewers.

That journal retracted the paper this month, citing numerous problems:

NIH neuroscientist up to 16 retractions

with 11 comments

Neuroscientist Stanley Rapoport just can’t catch a break.

Rapoport, who’s based at National Institute on Aging, is continuing to experience fallout from his research collaborations, after multiple co-authors have been found to have committed misconduct.

Most recently, Rapoport has had four papers retracted in three journals, citing falsified data in a range of figures. Although the notices do not specify how the data falsification occurred, Jagadeesh Rao, who was recently found guilty of research misconduct, is corresponding author on all four papers.

Back in December, Rapoport told us that a “number of retractions [for] Rao are still in the works:” Read the rest of this entry »

Journal retracts paper eight months after U.S. Feds announce findings of misconduct

without comments

In August, the U.S. Office of Research Integrity announced that a former postdoctoral fellow at the National Human Genome Research Institute (NHGRI) doctored data in two published papers.

It took one journal a little longer than five months to remove the researcher’s name from the co-author list, and replace one figure.

It took the second journal more than eight months to retract the paper.

Here’s the notice for “A BLOC-1 Mutation Screen Reveals that PLDN Is Mutated in Hermansky-Pudlak Syndrome Type 9,” published by the American Journal of Human Genetics (AJHG):

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

with 4 comments

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:

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

with one comment

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:

Another retraction for student who confessed to cooking data

without comments

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).  Read the rest of this entry »
