Lost citation snuffs out Aussie fire paper

A journal has retracted a 2016 paper on wildfires in Australia because the authors neglected to cite earlier work — an unintentional lapse, they said.

The article, “Projected changes in Australian fire regimes during the 21st century and consequences for Ecosystems,” appeared in the International Journal of Wildland Fire. The authors are Sandy Harrison and Douglas Kelley,  of the University of Reading, in the UK. Kelley appears to have done his share of the work as a PhD student at Macquarie University in Australia.

Journal corrects paper by researcher sanctioned for misconduct

A biology journal has issued a correction to a 2014 paper by a researcher with 11 retractions, citing “inadvertent errors” that don’t affect the conclusions.

The researcher, Rony Seger, was recently sanctioned by his institution (The Weizmann Institute in Israel) following a finding of “serious misconduct” involving data manipulation. Specifically, the institute barred him from supervising graduate students, even future ones; his lab is now dedicated to replicating his previous work, with the help of a technician.

Last month, Michal Neeman, vice president of The Weizmann Institute of Science, told us she wasn’t sure how many additional papers by Seger would need to be retracted or corrected.

Recently, one more was revealed — in the August issue of Molecular and Cellular Biology, the following correction notice appears:

Third retraction for former rising star found guilty of misconduct

A once-prominent researcher in the field of infectious disease — who was found guilty of misconduct last year— has had a third paper retracted, a 2006 article in PNAS.

Last year, the University of Dundee in Scotland found that Robert Ryan had committed research misconduct, which included misrepresenting clinical data and duplicating images in a dozen different publications. After a failed attempt to appeal the decision, Ryan resigned.

In April, we covered Ryan’s first two retractions – a 2012 paper in Molecular Microbiology, which cited image errors, and a 2011 paper in Journal of Bacteriology, which cited image duplication.

Now, PNAS has retracted a 2006 paper, which cites potential image duplication as well as “irregularities” in the data.

Here’s the retraction notice for “Cell–cell signaling in Xanthomonas campestris involves an HD-GYP domain protein that functions in cyclic di-GMP turnover:”

“The article must be retracted:” Journal pulls prostate cancer study

A 2016 paper exploring the biology of prostate cancer has been retracted due to figure manipulation.

According to the retraction notice, a reader contacted the journal Clinical Cancer Research in late 2016 with concerns that similar bands appeared multiple times in two images. The editors asked the paper’s corresponding author, Shahriar Koochekpour, about the issue and requested the raw data for the figures. But Koochekpour, based in the Departments of Cancer Genetics and Urology at Roswell Park Cancer Institute in Buffalo, New York, at the time of the study, could not locate the raw data.

Since the lab did not have raw data from such a relatively recent paper, the editors reached out to the research integrity officer at Roswell Park Cancer Institute to investigate. Indeed,  the research integrity officer contacted confirmed that two figures were problematic, and requested the paper be retracted.

Here’s the rather detailed retraction notice, published in July 2017, for “GRM1 is An Androgen-Regulated Gene and its Expression Correlates with Prostate Cancer Progression in Pre-Clinical Models:” Continue reading “The article must be retracted:” Journal pulls prostate cancer study

Journal retracts paper it says authors published twice. Authors disagree.

A journal has retracted a 2012 paper after determining that the authors had already published it elsewhere.

According to the retraction notice, the editors-in-chief of the Journal of Occupational Medicine and Toxicology concluded that the article had  been published in another journal—In Vitro Cellular & Developmental Biology – Animal—the previous month. The authors, however, did not agree to the retraction.

The research, led by Ali Khavanin, who is based at Tarbiat Modares University in Tehran, Iran and is corresponding author on both papers, evaluated whether the vibrations from industrial machinery can harm hearing in rabbits (1, 2).

Here’s the retraction notice for “Assessment of the influence of whole body vibration on Cochlear function”: Continue reading Journal retracts paper it says authors published twice. Authors disagree.

Work by group at Australian university faces scrutiny

A journal is investigating research by a group in Australia, after receiving “serious allegations” regarding a 2017 paper about treating eye burns.

The journal, Frontiers in Pharmacology, has issued an expression of concern (EOC) for the 2017 paper while it investigates. The notice does not specify the nature of the allegations.  Meanwhile, several other papers by the three researchers, based at Deakin University in Geelong, Australia, have also come under scrutiny. Late last month, Frontiers in Pharmacology retracted a 2015 paper by Kislay Roy, Rupinder Kanwar, and Jagat R Kanwar, citing image duplication. A 2015 paper in Biomaterials received a correction in May 2017, again flagging image duplication.

Roy, the first author on the papers, is a postdoctoral research fellow; Rupinder Kanwar, a middle author, is a senior lecturer; and Jagat R Kanwar, the corresponding author on all three, is head of the Nanomedicine-Laboratory of Immunology and Molecular Biomedical Research.

Gearóid Ó Faoleán, the ethics and integrity manager at Frontiers in Pharmacology, explained that the investigation into the flagged article is ongoing and the EOC “must serve as the extent of our public statement for the present.”

A spokesperson for Deakin University declined to comment on the allegations: Continue reading Work by group at Australian university faces scrutiny

Months after neuroscientist flagged errors, Nature journal corrects them — and more

When a neuroscientist noticed there were problems with his January 2017 paper in Nature Neuroscience, he didn’t wait for the journal to take action — instead, he published his concerns about four figures on PubMed Commons. Months later, the journal has issued formal corrections to those figures — along with several more.   

In February 2017, we praised Garret Stuber for alerting the scientific community to issues in his paper only 10 days after it first appeared online. On Twitter, he directed followers to the comment on PubMed Commons and asked them to retweet “for the sake of science integrity” — yet another example of how more researchers are taking matters into their own hands to alert readers to flaws in their papers. But according to the journal, the problems with the paper were more extensive than Stuber initially reported.

Drip, drip: UCLA investigation finds more image duplications

Image duplications and unsupported data continue to plague a network of cancer researchers that includes the former vice chancellor for research at the University of California, Los Angeles, James Economou.

On July 2, the editors at Cancer Research retracted a 2011 paper that Economou published as last author, saying it suffered from image duplication and unsupported figures. This is the second retraction we’re aware of to come out of an investigation by UCLA’s Office of Research Policy and Compliance that has touched this group of scientists.

Here’s the notice for “Molecular Mechanism of MART-1+/A*0201+ Human Melanoma Resistance to Specific CTL-Killing Despite Functional Tumor–CTL Interaction,” which says the retraction comes at the request of UCLA: Continue reading Drip, drip: UCLA investigation finds more image duplications

What a report into scientific misconduct reveals: The case of Frank Sauer

Oct. 3, 2011, was the beginning of the end for Frank Sauer’s tenure at the University of California, Riverside. On that day, an anonymous emailer contacted Sauer’s institution with accusations that the biochemist had cooked his research in at least eight papers over a 16-year period.

Sauer was found to have doctored images in studies using government money — nearly $3 million of it. He went on to lose his position at UC Riverside, several papers to retraction, and, in May, a subsequent legal battle over the severity of the federal sanctions. Along the way, he concocted a fantastic tale of sabotage against German scientists (like himself), replete with poison-pen letters and fabricated credentials. 

Retraction Watch has obtained a copy of UC Riverside’s report on the Sauer case through a public records request. The report, which is undated but which describes committee meetings and interviews from October 2011 to October 2012, lists 33 allegations of scientific misconduct against Sauer, 20 of which the committee determined to involve deception. Of the remaining 13, the committee either could not find proof of guilt or determined that the data were legitimate.

Science journal flags cancer paper under investigation for image manipulation

Science Signaling has issued an expression of concern for a 2016 paper, citing an institutional investigation into image manipulation.

According to a spokesperson for the journal, the corresponding author, Tanya Kalin, became concerned that two images in the paper had been manipulated. Kalin then notified the research integrity officer at Cincinnati Children’s Hospital Medical Center, where she is based.

On May 9 2017, Kalin alerted the journal to the investigation. A week later, the hospital’s research integrity officer followed up with the journal, flagging the figures under question.  The journal then prepared an expression of concern (EOC) to alert readers to the issues and the institution’s investigation.  

Here’s the EOC notice for “The transcription factor FOXF1 promotes prostate cancer by stimulating the mitogen-activated protein kinase ERK5:” Continue reading Science journal flags cancer paper under investigation for image manipulation
