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

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

Karel Bezouška, who broke into lab to tamper with investigation, has JACS paper retracted

jacsat_v136i001.inddKarel Bezouška, who, as we noted last year “broke into a lab refrigerator so he could tamper with samples being used to try to replicate the experiments during the investigation,” has had his fourth paper retracted.

Here’s the notice, for “Synthesis of Multivalent Glycoconjugates Containing the Immunoactive LELTE Peptide: Effect of Glycosylation on Cellular Activation and Natural Killing by Human Peripheral Blood Mononuclear Cells,” in the Journal of the American Chemical Society (JACS): Continue reading Karel Bezouška, who broke into lab to tamper with investigation, has JACS paper retracted

First retraction appears in case of cardiologist Poldermans

EBPOM_00219_M3Don Poldermans, the cardiology researcher in the Netherlands whose prominent career came to disgrace in a rather confusing scandal, finally has a retraction.

Poldermans, formerly of Erasmus Medical Center, copped to charges of misconduct but not of fraud in the case — which, if you speak Dutch, you can read about in detail here.

As we wrote in 2012: Continue reading First retraction appears in case of cardiologist Poldermans

Another retraction for sex researcher Weijmar Schultz

Willibrord Weijmar Schultz, the Groningen sex researcher (and Ig Nobel winner) who misused the 1985 thesis of an American scholar, and the work of another researcher, in at least five published articles, has tallied another retraction in the affair, his sixth.

As we reported earlier, Schultz had been cleared of plagiarism but found to have abused the work (in an “unintended and unknowing” fashion, we’re told) of one Diana Jeffrey, by taking passages from her dissertation without acknowledgement. These articles are pretty long in the tooth, having been published in the 1990s.

The latest, in the Journal of Sex Education and Therapy, appeared in 1992. Titled “Sexual rehabilitation after gynecological cancer treatment,” Schultz wrote it with a colleague H.B.M. Van de Wiel, whose name shows up on the other retractions, too.

According to the notice: Continue reading Another retraction for sex researcher Weijmar Schultz

Fourth retraction results from Cardiff investigation

mol immResearchers have retracted a fourth paper following an investigation at Cardiff University that found evidence of image manipulation by a researcher named Rossen Donev.

Here’s the notice for “The mouse complement regulator CD59b is significantly expressed only in testis and plays roles in sperm acrosome activation and motility,” a paper first published in Molecular Immunology in 2008: Continue reading Fourth retraction results from Cardiff investigation

Gut instinct: Intestinal flora paper yanked for plagiarism

frontcellinfectmicroA group of researchers in China has lost a paper on the human microbiome in Frontiers in Cellular and Infection Microbiology for cannibalizing much of it from previously published work by other scientists.

The article, titled “Human gut microbiota: dysbiosis and manipulation,” appeared on Sept. 27, 2012, and was written by a team from the Beijing Genomics Institute-Shenzhen. It has been cited just once, according to Thomson Scientific’s Web of Knowledge, by another paper in the same journal.

According to the retraction notice: Continue reading Gut instinct: Intestinal flora paper yanked for plagiarism

Here’s the most recent notice, from the British Journal of Clinical Pharmacology, of a paper that has been cited 23 times, according to Thomson Scientific’s Web of Knowledge: Continue reading Urology researcher in Iran has third paper retracted

Doing the right thing: Yale psychology lab retracts monkey papers for inaccurate coding

developmental scienceIn the midst of the holiday season, it’s a pleasure to be able to share the story of a scientist doing the right thing at significant professional cost — especially a researcher in psychology, a field that has been battered lately by scandal.

Sometime after publishing two papers — one in Developmental Science and another in the Journal of Personality and Social Psychology — Yale’s Laurie Santos and her students realized there were problems with their data. We’ll let Santos — who made sure to respond to our request for comment immediately, in the midst of holiday travel, so that we had all the details and could help get the word out — tell the story: Continue reading Doing the right thing: Yale psychology lab retracts monkey papers for inaccurate coding
