Doing the right thing: Psychology researchers retract after realizing data “were not analyzed properly”

cerebral cortexAmid an ongoing investigation, a group of psychology researchers at the University of Leuven (KU Leuven) in Belgium have taken a painful decision to retract a paper now that they’ve realized there were serious problems with one aspect of the work.

Here’s the notice for “The Emergence of Orthographic Word Representations in the Brain: Evaluating a Neural Shape-Based Framework Using fMRI and the HMAX Model,” by Wouter Braet, Jonas Kubilius, Johan Wagemans, and Hans P. Op de Beeck: Continue reading Doing the right thing: Psychology researchers retract after realizing data “were not analyzed properly”

Scientists doing the right thing: Malfunctioning lab equipment leads to retraction of neuroscience paper

cerebral cortexFor the second time inside of a week, we come to praise scientists who did the right thing when they realized their lab equipment or reagents weren’t performing as expected.

Here’s the retraction of a 2011 paper in Cerebral Cortex: Continue reading Scientists doing the right thing: Malfunctioning lab equipment leads to retraction of neuroscience paper

A model retraction in the Journal of Neurochemistry for “unexpected effect” of a filter

jneurochemThey say that a poor workman blames his tools. If you’re a scientist and you discover your tools don’t do exactly what you thought they did, however, the right thing to do is let other scientists relying on your work know.

That’s what the University of Auckland’s Nigel Birch and colleagues did recently, after a 2012 study they published in the Journal of Neurochemistry didn’t hold up. Here’s the notice, which we’d consider a model for retractions everywhere: Continue reading A model retraction in the Journal of Neurochemistry for “unexpected effect” of a filter

Mitochondrial fission paper falls for fusing data from earlier work

brain research coverA team of neuroscientists in Japan has lost their 2012 article in Brain Research for duplicating elements of a figure from a paper they’d published earlier that year in another journal.

The article, “Dynamic changes of mitochondrial fission proteins after transient cerebral ischemia in mice,” came from a lab at Okayama University. The last author was Koji Abe. According to the retraction notice:

Duplicate publication of headache paper earns Expression of Concern, erratum

eottA 2003 paper is now subject to an Expression of Concern after its author reused a lot of its material in a 2007 paper.

Here’s the Expression of Concern for “New therapeutic target in primary headaches – blocking the CGRP receptor” by Lars Edvinsson of the University of Copehagen: Continue reading Duplicate publication of headache paper earns Expression of Concern, erratum

Second retraction appears for University of Wisconsin neuroscientist who faked images

brain researchA University of Wisconsin scientist who was found by the Office of Research Integrity (ORI) to have faked data in two papers, has had a second study retracted.

Here’s the notice: for “Secretory phospholipase A2 IIA is up-regulated by TNF-α and IL-1α/β after transient focal cerebral ischemia in rat,” by Rao Adibhatla and colleagues and originally published in Brain Research in February 2007: Continue reading Second retraction appears for University of Wisconsin neuroscientist who faked images

Kenji Okajima retraction count grows to five

We’ve been following the case of Kenji Okajima, a professor at Nagoya City University in Japan who was suspended for six months following an investigation into work in his lab. Bits of the story — including at least one other university investigation, and scrutiny of Okajima’s colleagues, one of whom was fired — have been dribbling out for almost two years since a retraction notice in the Journal of Neuroscience.

In all, it looks as Nagoya found evidence of misconduct in 19 papers. The Journal of Neuroscience retraction appeared in 2011, and another showed up in the Journal of Immunology last year. Now there are three more: One in Translational Research and two in Blood.

Here’s the notice from Translational Research: Continue reading Kenji Okajima retraction count grows to five

U Wisconsin neuroscientist who faked images has first paper retracted

jbc315Rao Adibhatla, a University of Wisconsin scientist who was found by the Office of Research Integrity (ORI) to have faked data in two papers, has had one of those studies retracted.

Here’s the notice for “CDP-choline significantly restores phosphatidylcholine levels by differentially affecting phospholipase A2 and CTP: phosphocholine cytidylyltransferase after stroke,” by Adibhatla and a number of colleagues in the Journal of Biological Chemistry (JBC): Continue reading U Wisconsin neuroscientist who faked images has first paper retracted

MIT lab retracts Cell synapse tagging paper for falsification or fabrication

cell feb 2013A rising star at MIT has retracted a paper after an investigation found that her former postdoc had “falsified or fabricated figures.”

Alice Ting, winner of an NIH Directors Pioneer Award and named one of Technology Review’s “Innovators Under 35,” published the paper, “Imaging Activity-Dependent Regulation of Neurexin-Neuroligin Interactions Using trans-Synaptic Enzymatic Biotinylation,” in Cell in 2010 along with Amar Thyagarajan.

The notice is refreshingly detailed given the circumstances: Continue reading MIT lab retracts Cell synapse tagging paper for falsification or fabrication
