Brain paper retracted after university report finds “substantial data misrepresentation”

jneurosci_coverThe Journal of Neuroscience is retracting a 2012 paper on how estrogen produced in the brain shapes the auditory system on the basis of “a report from Northwestern University that describes substantial data misrepresentation” in the paper.

The paper, “Mechanistic Basis and Functional Roles of Long-Term Plasticity in Auditory Neurons Induced by a Brain-Generated Estrogen,” is, according to PubMed, the last one published by its last (and corresponding) author Raphael Pinaud, and first author Liisa Tremere, who were both at Northwestern University at the time. Before his position at Northwestern, Pinaud held positions at the University of Oklahoma and the University of Rochester.

Pinaud and Tremere jointly published a handful of papers on the role of estrogen in the auditory system of the brain starting in 2009, some of which are co-authored by two of the other researchers on the current paper, which has been cited 8 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction notice:

Science retracts troubled gay canvassing study against LaCour’s objections

science coverFollowing revelations of data issues and other problems (which crashed our server last week), Science is retracting a paper claiming that short conversations could change people’s minds on same-sex marriage.

The co-author who admitted to faking the data “does not agree” to the retraction, according to Science. Here’s more from the note: Continue reading Science retracts troubled gay canvassing study against LaCour’s objections

Fluid mechanics article retracted with no explanation

JHeatTransf_ak7An article published earlier this year has been retracted from the  Journal of Heat Transfer. But the retraction notice gives no information about what was amiss.

The article is entitled “Neural Network Methodology for Modeling Heat Transfer in Wake Flow,” and the retraction notice, in full, reads: Continue reading Fluid mechanics article retracted with no explanation

Bully for you! Duplication earns demerit for school cruelty paper

Trauma-kashan3Archives of Trauma Research has retracted a 2014 paper on bullying by a group in Iran who appear to have been double-fisted in their approach to publishing.

The article, “Epidemiological Pattern of Bullying Among School Children in Mazandaran Province, Iran,” was written by researchers from Shahid Beheshti University of Medical Sciences, in Tehran. Its conclusions:

Different forms of bullying have a distinct nature and the epidemiological pattern indicates that bullying exists in the Iranian schools. Thus, the effective bullying prevention and appropriate intervention programs are recommended.

Here’s the notice:

Heart repair study retraction marks second for Mercer University researcher

BasicResCardio_ak12Authors of a study on cardiac repair after heart attack are retracting it from Basic Research in Cardiology because they used “the same samples… to represent two distinct groups on two occasions.”

We find the language of the retraction somewhat confusing, but to the best of our understanding it means that they compared apples to the exact same apples.

The study, published online in 2012, examined the mechanism behind the beneficial effects of a procedure called postconditioning in treating heart attacks. Here’s the retraction notice: Continue reading Heart repair study retraction marks second for Mercer University researcher

Chip slip: Irreproducibility erases computer memory paper

nanoscaleResearchers at the Chinese Academy of Sciences have retracted a paper in Nanoscale about an experimental computer chip after they were unable to recreate their published results.

“We retract this article to avoid misleading readers and intend to undertake further tests to confirm our previous results,” they write in the notice.

The scientists are working on developing a chip that uses resistive random-access memory, which allows a huge amount of information to be stored in a tiny package and accessed quickly while using very little power. A number of companies are working on the technology, but none have successfully commercialized it.

Here’s the notice for “High uniformity and improved nonlinearity by embedding nanocrystals in selector-less resistive random access memory” (free, but requires login): Continue reading Chip slip: Irreproducibility erases computer memory paper

“The first author assumes all responsibility:” Malaria vaccine article retracted for image manipulation

InfectAndImmunAuthors of a 2012 article in Infection and Immunity investigating a malaria vaccine strategy are retracting it because it “contains several images that do not accurately reflect the experimental data.”

The paper, “Fine Specificity of Plasmodium vivax Duffy Binding Protein Binding Engagement of the Duffy Antigen on Human Erythrocytes,” has been cited 9 times, according to Thomson Scientific’s Web of Knowledge.

The retraction notice places the blame for the image shenanigans squarely on the first author, Asim Siddiqui, who is currently listed on LinkedIn as a faculty member at the College of Applied Medicine at King Saud University in Saudi Arabia.

Here’s the notice: Continue reading “The first author assumes all responsibility:” Malaria vaccine article retracted for image manipulation

JAMA vitamin-hip fracture study earns Expression of Concern for integrity issues

jama coverJAMA has issued an Expression of Concern about a 2005 study of whether two different types of vitamin B could prevent broken hips in people who’d suffered strokes.

The original study concluded:

In this Japanese population with a high baseline fracture risk, combined treatment with folate and vitamin B12 is safe and effective in reducing the risk of a hip fracture in elderly patients following stroke.

Here’s the notice for the study, “Effect of folate and mecobalamin on hip fractures in patients with stroke: a randomized controlled trial:” Continue reading JAMA vitamin-hip fracture study earns Expression of Concern for integrity issues

The “worst moment of my scientific career:” Two bird migration articles brought down by analytical error

JAvianBio_ak19Evolutionary and conservation biologists in Spain are retracting two articles – one from the Journal of Avian Biology and the other from Ardeola – because they discovered a fatal flaw in their analysis.

The Journal of Avian Biology article, “Are European birds leaving traditional wintering grounds in the Mediterranean?” aimed to determine whether the abundance of passerines had decreased in recent decades, but failed to control for birds that may have gotten killed by hunters. Although it was published in January, we can only find an abstract from its acceptance by the journal in November 2014.

The authors detail the saga of their error in the retraction notice: Continue reading The “worst moment of my scientific career:” Two bird migration articles brought down by analytical error
