Four retractions follow Swedish government findings of negligence, dishonesty

242915_1uu_logoA Swedish ethical review board has censured two biologists and their employer, Uppsala University, for events related to “extensive image manipulations” in five papers published between 2010 and 2014. The case has led to criticism from an outside expert — who brought the allegations to Uppsala — over the current system in Sweden for handling such investigations.

Four of the papers have been retracted, and the authors have requested a correction in the fifth.

After an eight-month investigation, in September the government-run Expert Group for Scientific Misconduct at the Central Ethical Review Board in Stockholm, Sweden, concluded that Uppsala professor Kenneth Söderhäll — who has published more than 200 papers — and lecturer Irene Söderhäll acted “negligently” and “dishonestly” by Continue reading Four retractions follow Swedish government findings of negligence, dishonesty

New developments cause authors to pull paper on drugs’ environmental impact

integrated envThe authors of an article about the effects of pharmaceutical drugs on the environment have retracted it before publishing the final version due to new developments in the field, which would have required a major revision.

The authors pulled the paper from Integrated Environmental Assessment and Management before it went through the final publication process – such as copyediting and proofreading – after they learned about new findings related to assessing to the risks of human exposures to pharmaceuticals in the environment.

We’d try to figure out which portions of the paper might need updating, but publisher Wiley recently pulled the original article and abstract, against the journal editor’s wishes.

Here’s the retraction note: Continue reading New developments cause authors to pull paper on drugs’ environmental impact

A bullshit excuse? My lab notebook “was blown into a manure pit”

CleanA researcher who studies how to turn dairy cattle manure into natural gas falsified and fabricated data in a journal article and failed to declare a commercial conflict of interest, a Washington State University investigation has found.

The study “Evaluation of Co-Digestion at a Commercial Dairy Anaerobic Digester” was published in 2011 in the journal CLEAN: Soil, Air, Water. First author Craig Frear was a Ph.D. student at WSU Pullman when the study was carried out and an assistant professor at the time of the investigation. The editor-in-chief of CLEAN, Prisca Henheik, told us that the retraction is a done deal even though it has not been posted online: Continue reading A bullshit excuse?

Voinnet’s notice count grows, as he notches his 18th correction

home_coverOlivier Voinnet, a high-profile plant scientist at ETH Zurich, has earned a mega-correction. It wrapped up a rough year for the biologist, which included his seventh retraction, and a CNRS investigation that found evidence of misconduct.

This latest correction, to a paper on the mechanisms behind RNA silencing in Arabidopsis, was published in RNA. The 2007 paper has been cited 101 times, according to Thomson Scientific’s Web of Knowledge. The corrigendum modifies three figures in total.

The notice is long, so we’re not going to post the whole thing here. The first error in “Transitivity in Arabidopsis can be primed, requires the redundant action of the antiviral Dicer-like 4 and Dicer-like 2, and is compromised by viral-encoded suppressor proteins” is a clarification to a legend:

Neuroscience paper retracted after colleagues object to data publication

frontiersA paper published this October in the journal Frontiers In Neuroscience was retracted the following month because the authors’ collaborators did not give them permission to publish some of the data.

The paper detailed how and why the authors use the software program Nengo to test large simulations of nervous system networks. As part of the research, the authors tested five systems, one of which they were working on with another group. Due to a “miscommunication,” the authors thought they had received permission to publish the data; they plan to resubmit a paper describing the other four systems.

Here’s the official retraction note: Continue reading Neuroscience paper retracted after colleagues object to data publication

Paper pulled when authors backtrack on identifying mad cow disease in Texas

Journal food protectionA journal is pulling a paper that reported a grain sample in Texas tested positive for mad cow disease after the authors asked to change the results to say the sample contained “animal protein prohibited for use in ruminant feed.”

Shortly after the paper was published in October, the authors contacted the Journal of Food Protection to retract the finding that the grain sample tested positive for bovine spongiform encephalopathy (BSE). After review, the journal decided to retract the entire paper, with the authors’ agreement, citing changes that “significantly affect” the findings.

JFP scientific editor Lauren Jackson filled us in on some details: Continue reading Paper pulled when authors backtrack on identifying mad cow disease in Texas

JAMA retracts osteoporosis paper with manipulated data

Screen Shot 2015-12-29 at 10.48.49 AMA JAMA study on an inexpensive treatment for osteoporosis has been retracted because the first author falsified or fabricated data. We’ve been expecting this one: An investigation at Women’s College Hospital in Toronto, the bone researcher’s former workplace, had already revealed issues with the paper.

An internal memo sent to staff (available in full here) in October explained that the investigation had found “unequivocal evidence of systematic data manipulation” by Sophie Jamal, who had already resigned from her positions at WCH and the University of Toronto.

The study appeared to show that nitroglycerin ointment could have a small positive effect on bone mineral density in postmenopausal patients. It’s been cited 30 times, according to Thomson Scientific’s web of Knowledge. (That’s two more times than when we last reported on the paper: It was cited once by the investigation, and once by a paper that was published earlier in October, but had not yet been indexed.)

Here’s the retraction note for “Effect of Nitroglycerin Ointment on Bone Density and Strength in Postmenopausal Women: A Randomized Trial:”

Neuroanatomy paper riddled with errors pulled by authors

Journal-of-NeurosurgeryAuthors have retracted a paper from the Journal of Neurosurgery that contained many errors, including mislabeled figures, anatomical errors, and mismatched citations. They said that the paper’s preparation was rushed and not all authors had a chance to verify that it was accurate.

Two of the authors of the paper had previously contacted the journal to request the paper be withdrawn. Jo Ann Eliason, communications manager for the Journal of Neurosurgery, said that the withdrawal request came too late, since the paper had already been published online: Continue reading Neuroanatomy paper riddled with errors pulled by authors

Authors retract antioxidant paper after more work reverses their conclusion

Screen Shot 2015-12-03 at 12.29.58 PM

The authors of a paper about the benefits of an antioxidant found in blueberries known as pterostilbene have retracted it after their subsequent research suggested the antioxidant might actually be harmful.

The paper presented evidence that the antioxidant might help rats after heart attack, in part by inhibiting cell death (apoptosis). But according to the retraction note, more work

found that pterostilbene might induce apoptosis in the heart and can be harmful, and we are now focusing on the phenomenon.

The rest of the retraction note for “Pterostilbene attenuates inflammation in rat heart subjected to ischemia-reperfusion: role of TLR4/NF-κB signaling pathway,” published in the International Journal of Clinical and Experimental Medicine, suggests that the authors would consider republishing their findings if they became more confident in the data:

Authors retract meningitis paper over permission — but data are in a public database

plos1A study characterizing subtypes of the bacteria that cause bacterial meningitis is being retracted after the authors didn’t have permission to publish the data, even though the data itself remain available in a public database.

The paper, in PLOS ONE, relied on a laboratory collection of patient samples. In October, the authors retracted it because they “did not have permission” from the laboratory “to publish the data in their current form.” The data — anonymized — are now available at PubMLST.

Here’s the retraction notice, published on October 16: Continue reading Authors retract meningitis paper over permission — but data are in a public database
