Last March, a PhD student at Harvard filed a misconduct allegation against his mentor, a prominent stem cell researcher. Three months later, he was taken from his home by police in the middle of the night for a forced psychiatric evaluation.

One of the retracted papers in the Journal of Neurosurgery (JNS) had multiple problems that were “too extensive to revise,” according to the lengthy retraction notice, relating to issues with authorship, data analyses, and patient enrollment. The notice is signed by first author Hua Liu of the Nanjing Medical University in China.
Liu is also the first author of another recently retracted paper in Frontiers in Neuroscience, pulled for incorrectly categorizing patients.
In 2011, authors of a Nature letter caught some flak for issuing a lengthy correction to a neuroscience paper that had raised eyebrows within days of publication — including some suggestions it should be retracted.
The correction notice, published months after the original letter, cited errors in image choice and labeling, but asserted the conclusions remained valid.
Now, those conclusions appear up for debate. In a recent Nature Brief Communications Arising (BCA) article, a team that raised concerns about the paper five years ago says they are unable to reproduce the results. But the authors of the original paper aren’t convinced: They argue that the BCA fails to cite important evidence, has a “complete absence or low quality of analysis,” and the scientists disregard some of their data.
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.
So ends a judge’s September 30, 2016 opinion dismissing a case brought in 2014 by Andrew Mallon, a former Brown University postdoc, alleging that his advisor and former business partner, John Marshall, had published a paper in 2013 in PLOS Biology that should have listed him as a co-author.
As with most court cases, this one had a long backstory: An earlier version of the paper had listed Mallon as a co-author, but was rejected by Neuron in 2011; after the authors had a dispute over the data, a different version of the manuscript was submitted to PLOS Biology in 2012, leaving Mallon off the co-author list. So Mallon had sued to have the paper retracted.
In communications with Retraction Watch and other media, as well as during depositions of the plaintiffs, Mallon referred frequently to allegations of scientific misconduct, including the fact that the first author of the PLOS Biology paper had an unrelated paper retracted in 2010 for duplicated data. However, this case was brought under the Copyright Act, which focused on the authorship dispute.
Kevin Tottis, who represented Marshall and co-defendant Dennis Goebel, told Retraction Watch his clients “are delighted with the judge’s decision.” Massachusetts District Court Judge Timothy Hillman, he said, Read the rest of this entry »
Two remaining charges against a Parkinson’s researcher recently convicted of fraud have been dropped by an Australian court.
In October, Caroline Barwood, formerly at the University of Queensland (UQ) in Brisbane, was found guilty of five out of seven charges. Subsequently, Barwood was handed two suspended sentences: one for two years, and another for 15 months, both to be served concurrently. She will not serve jail time.
Initially, Barwood pleaded not guilty to the three charges of fraud and four instances of attempted fraud — unlike her former UQ colleague Bruce Murdoch, who pleaded guilty to 17 fraud-related charges in March, and also earned himself a two-year suspended sentence.
Barwood was found guilty of five charges against her, but the jury could not reach a majority verdict on one count of fraud and another of attempted fraud. She was asked to re-attend court for a “mention.”
On December 6, those charges were withdrawn. Barwood told us: Read the rest of this entry »
That’s the sound of learning that a third scientist you worked with committed misconduct.
In the last two years, we reported on two retractions for neuroscientist Stanley Rapoport, the result of misconduct by two different first authors. We’ve since discovered more retractions resulting from those cases — and a new retraction stemming from the actions of yet another co-author.
Although the latest retraction notice doesn’t reveal the reason for retraction, both the journal editor and Rapoport — based at the National Institute on Aging (NIA), part of the National Institutes of Health (NIH) — confirmed to us that it is the result of misconduct by the last author, Jagadeesh Rao. According to Rapoport, a “number of retractions [for] Rao are still in the works.”
We asked Rapoport for his reaction to multiple cases of misconduct by his colleagues, including the two first authors we’ve already reported on, Fei Gao and Mireille Basselin:
The abstract — published online in Frontiers in Public Health after being accepted November 21 — reported findings from anonymous online questionnaires completed by 415 mothers of home-schooled children 6-12 years old. Nearly 40 percent of children had not been vaccinated, and those that had were three times more likely to be diagnosed with neurodevelopmental disorders such as autism, the study found.
After receiving criticism on Twitter, Frontiers released a public statement, noting that the study was only “provisionally accepted but not published,” and is being re-reviewed. When asked for a comment, a Frontiers spokesperson referred us to the statement. Read the rest of this entry »
In March, 2013, a graduate student joined the lab of a prominent researcher in Australia, investigating new therapies for Parkinson’s. A few months later, everything fell apart.
In September 2013, the University of Queensland (UQ) announced it was retracting one of the lab’s papers, returning the money used to fund the research and launching a fraud investigation. Since then, the scandal has grown to the point where the lead researcher and his co-author have been convicted of fraud in an Australian court.
Now, the graduate student is fighting back. After losing her research project and being escorted off campus for allegedly erratic behavior, she has appealed to UQ to reimburse her for tens of thousands of dollars in tuition, and is now awaiting a verdict from a government ombudsman. The graduate student goes by “Dominique,” which is not her real name; Retraction Watch is keeping her identity confidential to protect her privacy. Read the rest of this entry »
The 2012 paper in the Indian Journal of Dermatology, Venereology and Leprology (IJDVL) told the tale of a 14-year old boy with Delleman syndrome, a condition that often results in the development of cysts within the cavities of the skull, leading to malformations in the eyes, brain, and skin.
Mabel Nocito, the study’s first and corresponding author from Hospital Churruca in Buenos Aires, Argentina told us the parents initially gave permission to publish their son’s picture, but then became concerned when they realized the paper was freely accessible: Read the rest of this entry »
