Doing the right thing: Physicists retract paper after becoming aware of “a fundamental error”

prl-bannerThe authors of a paper in Physical Review Letters have retracted it, after another researcher pointed out a mistake.

F. Sattin and D.F. Escande write in the notice for “Alfvénic Propagation: A Key to Nonlocal Effects in Magnetized Plasmas” (which is behind a paywall) that after the paper was published, they “we became aware of a fundamental error in the normalization of our equations.” Excerpt: Continue reading Doing the right thing: Physicists retract paper after becoming aware of “a fundamental error”

MS paper second to fall following University of Queensland investigation

aphasiologyTwo former University of Queensland researchers have lost another paper following an investigation into their work.

In September, the university announced that a paper in the European Journal of Neurology by Bruce Murdoch and Caroline Barwood would be retracted because

no primary data can be located, and no evidence has been found that the study described in the article was conducted.

The university continued its investigation, and announced today that: Continue reading MS paper second to fall following University of Queensland investigation

“Unable to dispel the doubts,” authors lose protein structure paper

ebjA suggestion: If you’re going to use the words “overestimated accuracy” in the title of your paper, you’d better make sure you aren’t guilty of the same yourself.

A group of authors in China has lost their June 2013 paper in the European Biophysics Journal because they appear to have misinterpreted their data.  The paper, “Overestimated accuracy of circular dichroism in determining protein secondary structure,” came from chemists at Fudan University in Shanghai, and purported to find that:

Biotech company retracts Parkinson’s treatment study after “possible deviation from protocol”

LCTLiving Cell Technologies (LCT), a biotech company headquartered in Australia, has retracted a 2011 paper purporting to show that their product reversed Parkinson’s symptoms in rats after “being unable to reconfirm their reported results and a possible deviation from the protocol.”

LCT is developing NTCELL, which, according to their site: Continue reading Biotech company retracts Parkinson’s treatment study after “possible deviation from protocol”

Neurology expresses concern over dementia study after authors report error in analysis

neurologyNeurology has issued an expression of concern over a 2013 article by a group of scientists in The Netherlands and the United States who found a potentially devastating error in their analysis.

The article, “Structural and functional brain connectivity in presymptomatic familial frontotemporal dementia,” came from the lab of John C. van Swieten, of Erasmus University in The Netherlands. According to the abstract of the article:  Continue reading Neurology expresses concern over dementia study after authors report error in analysis

Psychology researcher explains how retraction-causing errors led to change in her lab

jperssocpsychLast month, we brought you the story of two retractions by Yale’s Laurie Santos because the team discovered errors in the way the first author had coded the data. That first author, Neha Mahajan, took full responsibility for the coding problems, according to the retraction notices, and a university investigation cleared her of any “intentional, knowing, reckless, or grossly negligent action.”

But a few of our readers noted that the papers refer to a second coder on some of the experiments, and have questioned whether that’s compatible with Mahajan being solely responsible for the errors.

We asked Santos earlier this week to explain the apparent discrepancy, which she did along with a description of how her lab has made changes to prevent such errors in the future: Continue reading Psychology researcher explains how retraction-causing errors led to change in her lab

Doing the right thing: Authors retract protein paper after finding experimental errors

embo reportsA group of researchers in the Netherlands has retracted a paper once they realized that the findings weren’t reproducible and that there had been an error in the experiments.

Here’s the notice for “Ubiquitin‐specific protease 4 is inhibited by its ubiquitin‐like domain,” by MP Luna‐Vargas, AC Faesen, WJ van Dijk, M Rape, A Fish, and TK Sixma: Continue reading Doing the right thing: Authors retract protein paper after finding experimental errors

Doing the right thing: Authors retract brain paper with “systematic human error in coding”

fronthumneuroA group of Swiss neurologists have lost their 2013 article in Frontiers in Human Neuroscience after reporting that their data were rendered null by coding errors.

The article, “Spontaneous pre-stimulus fluctuations in the activity of right fronto-parietal areas influence inhibitory control performance,” purported to find that: Continue reading Doing the right thing: Authors retract brain paper with “systematic human error in coding”

Simulation slip-up leads to retraction of explosives paper

applsci-logoApplied Sciences has retracted a 2012 article by a researcher whose efforts to model a particular kind of explosion called a shaped charge proved to be a dud.

The paper, “Steady State Analytical Equation of Motion of Linear Shaped Charges Jet Based on the Modification of Birkhoff Theory,” was written by Seokbin Lim, a mechanical engineer in the Energetic Systems Research Group at  New Mexico Tech, in Socorro.
