ORI sanctions collaborator of Nobel winner Buck for data fabrication

ori logoThe Office of Research Integrity has sanctioned a former researcher in the lab of Linda Buck, winner of the 2004 Nobel Prize in Physiology or Medicine, for falsifying data in two papers written with the support of grants from the National Institutes of Health.

The researcher, Zou Zhihua, worked with Buck as a post-doc at Harvard and then at the Fred Hutchinson Cancer Research Center, in Seattle, Buck’s current home. After leaving there in 2005, he spent three years at the University of Texas Medical Branch in Galveston, and now appears to be a faculty member at Jilin University in China.

According to the report:

Diabetes researcher Cory Toth up to seven retractions

tothA University of Calgary diabetes researcher, Cory Toth, who told us earlier this year that he would cease publishing in the scientific literature, has two more retractions, making seven.

Both appear in Neurobiology of Disease. Here’s the notice for “Differential impact of diabetes and hypertension in the brain: Adverse effects in white matter:”

Researchers repeat retracted study, republish in same journal sans first author

biol psychWe’ve been following the case of Amine Bahi, a neuroscience researcher in the United Arab Emirates who has managed something unusual in the annals of Retraction Watch: Three different retractions for three completely different reasons. One was for “legal issues,” another was for lack of IRB approval, and the third was for using RNAs from the wrong species.

Now, Bahi’s co-authors have repeated the last of those studies with the right RNAs, and have republished their paper in the same journal, Biological Psychiatry — but without Bahi.

The retraction notice for “Blockade of Protein Phosphatase 2B Activity in the Amygdala Increases Anxiety- and Depression-Like Behaviors in Mice” now includes this final paragraph: Continue reading Researchers repeat retracted study, republish in same journal sans first author

Serial fakery: Researcher found to have committed misconduct at Harvard and Oxford

harvardA former Harvard postdoc who was found guilty of faking data at Oxford as a student did the same thing at Harvard, according to the Office of Research Integrity (ORI).

We first wrote about Helen Freeman in February, when we covered a retraction in Cell Metabolism that said the UK’s Medical Research Council had found that she committed misconduct while working as a student at Oxford. Today, a Federal Register notice from the ORI reports that Freeman faked images in a manuscript submitted to Nature while she was working on federally funded grants at Harvard Medical School and Beth Israel Deaconess Medical Center.

From the ORI’s report: Continue reading Serial fakery: Researcher found to have committed misconduct at Harvard and Oxford

Diabetes researcher who says he will no longer publish now up to five retractions

Cory Toth, the University of Calgary diabetes researcher who told us last month he would stop publishing in science following a string of inappropriate manipulations, has retracted another paper.

Here’s the notice in Brain for “Intranasal insulin prevents cognitive decline, cerebral atrophy and white matter changes in murine type I diabetic encephalopathy:” Continue reading Diabetes researcher who says he will no longer publish now up to five retractions

Authors retract study suggesting magnesium prevents Alzheimer’s in mice

j neuroscienceThe authors of a 2013 Journal of Neuroscience study suggesting that “elevation of brain magnesium…may have therapeutic potential for treating [Alzheimer’s disease] in humans” have retracted it after finding errors in the work.

Here’s the original abstract:

Anonymous blog comment suggests lack of confidentiality in peer review — and plays role in a new paper

neuronA new paper in Intelligence is offering some, well, intel into the peer review process at one prestigious neuroscience journal.

The new paper is about another paper, a December 2012 study, “Fractionating Human Intelligence,” published in Neuron by Adam Hampshire and colleagues in December 2012. The Neuron study has been cited 16 times, according to Thomson Scientific’s Web of Knowledge.

Richard Haier and colleagues write in Intelligence that Continue reading Anonymous blog comment suggests lack of confidentiality in peer review — and plays role in a new paper

Lack of citation prompts correction in Nature journal

nature communicationsIt’s not unusual to hear authors bemoan the fact that a new paper doesn’t cite their work that set the stage for a scientific advance. “The journal limited me to [a seemingly abitrary number of] references,” authors sometimes shrug, with or without apology. This week, however, we found a case of that which seems to have been resolved to everyone’s satisfaction.

The authors of a September 2013 article in Nature Communications have issued a correction for the piece, which failed to cite the source of a key step in their experiment.

The article, “Val66Met polymorphism of BDNF alters prodomain structure to induce neuronal growth cone retraction,” came from the lab of William “Clay” Bracken, a biochemist at Weill Cornell Medical College. According to the abstract: Continue reading Lack of citation prompts correction in Nature journal

Fraud topples second neuroscience word processing paper

neuroimageWe have a second retraction from a group of neuroscience researchers in Belgium who discovered fatal errors in their work on how the brain sets about the task of reading written language. Spoiler alert: Turns out those errors weren’t errors after all.

As we reported back in May, the group, from the University of Leuven, was unable to replicate certain fMRI findings in a November 2012 article in Neuroscience. At the time, Hans P. Op de Beeck, who led the group, told us: Continue reading Fraud topples second neuroscience word processing paper

Doing the right thing: Team finds data merge error in depression paper, retracts

bbicover114A team of neuroscientists from Sweden has retracted their 2013 paper in Brain, Behavior, and Immunity after discovering that they’d made a mistake while merging their data.

According to the abstract, the study, “Lower CSF interleukin-6 predicts future depression in a population-based sample of older women followed for 17 years,” purported to find that: Continue reading Doing the right thing: Team finds data merge error in depression paper, retracts
