Canadian researchers in legal battle over investigation object to third retraction

The Journal of Clinical InvestigationA third retraction — and a notice of concern — have emerged from the investigation into a husband and wife research team at the University of Toronto that found evidence of faked images and duplicated data.

The problem, according to the latest retraction note for Sylvia Asa and Shereen Ezzat, in the Journal of Clinical Investigation: Portions of the RT-PCR gels “are duplicated in this publication and in a subsequent publication.” That subsequent publication is a 2003 paper that has received a Notice of Concern from the American Journal of Pathology.

According to the retraction note, co-author Gillian E. Wu of York University signed off on the journal’s decision, but Asa, Ezzat and second author Lei Zheng dissented to the retraction. Third author Xian-Feng Zhu couldn’t be reached. Although corresponding author Asa noted that “the initial screen of these samples support the conclusions made in the paper,” the JCI made its position perfectly clear in the note:

“Unethical behavior” breaks crystallography paper

Molecules and Cells

A 2011 paper about the crystal structure of a transcription regulator has been pulled by Molecules and Cells for “unethical behavior by the authors.”

Unfortunately, we can’t say much more than that, because the notice doesn’t, either: Continue reading “Unethical behavior” breaks crystallography paper

Plague or anthrax on the subway? Think again, says now-corrected study

Cell SystemsAuthors of a widely covered study that documented traces of plague and anthrax on surfaces across New York City have revised the paper after public health officials challenged their interpretations of the data.

It’s hard to overestimate the attention these findings received when first published.

“Bubonic plague found in NYC subway,” wrote The Daily Beast.

“Your subway seat mate: Bubonic plague, anthrax, & mysterious DNA,” said Yahoo!

“NY subway has bubonic plague,” declared Newser.

Not so fast. In an erratum published July 29, the authors write: Continue reading Plague or anthrax on the subway? Think again, says now-corrected study

Inquiry into duplications reveals “multiple” image problems in tumor study

STEM_17_1.c1.inddA paper on how abnormal stem cells can cause benign bone tumors has been retracted by Cell Stem Cell after an inquiry into image duplications also uncovered “multiple instances of inappropriate western blot image adjustment.”

The first two authors “declined” to sign the retraction, according to the notice.

Besides confirming initial suspicions that images had been duplicated, the editors also found “multiple instances of inappropriate western blot image adjustment, such as uneven compression of images and removal of background elements:”

Golden rice paper pulled after judge rules for journal

home_coverThe American Journal of Clinical Nutrition is retracting a paper that showed genetically engineered rice serves as an effective vitamin A supplement after a Massachusetts judge denied the first author’s motion for an injunction against the publisher.

The journal announced plans to retract the paper last year following allegations that the paper contained ethical mis-steps, such as not getting informed consent from the parents of children eating the rice, and faking ethics approval documents.

Last July, first author Guangwen Tang at Tufts University filed a complaint and motion for preliminary injunction against the journal’s publisher, the American Society for Nutrition, to stop the retraction.

According to the ASN, on July 17, a Massachusetts Superior Court “cleared the way” for the publisher to retract the paper. So they have, as of July 29. Here’s more from the retraction notice:

Voinnet notches second retraction, two more corrections

PNASOlivier Voinnet — a plant researcher who was recently suspended for two years from the Centre national de la recherche scientifique (CNRS) after an investigation by ETH Zurich and CNRS found evidence of misconduct — has issued his second retraction and two more corrections.

PNAS posted the retraction earlier this week for a 2006 article after an inspection of the raw data revealed “errors” in study images. Authors confirmed the issues in some figures and revealed “additional mounting mistakes” in others.

Voinnet has promised to issue retractions and corrections for every study that requires them. These latest notices bring our tally up to nine corrections, two retractions and one Expression of Concern.

Judge dismisses cardiac stem cell researchers’ lawsuit against Harvard

A Massachusetts judge has dismissed a lawsuit by researchers who argued that an investigation by Harvard cost them job offers.

Last year, Piero Anversa, a stem cell researcher at the Brigham & Women’s Hospital, and a colleague, Annarosa Leri, sued Harvard over an investigation into their work that they claim damaged their reputations: Continue reading Judge dismisses cardiac stem cell researchers’ lawsuit against Harvard

Retracting duplicated paper “may damage the integrity of the literature,” says plant journal editor

In Vitro Cellular & Developmental Biology - PlantIn Vitro Cellular & Developmental Biology – Plant has flagged a 2004 article that was “accidentally” duplicated from another paper published earlier that year — but did so in the form of a publisher’s erratum, not a retraction.

The editor of the journal justified the decision by arguing that the duplicated paper had been cited “over a dozen times” and was old enough to not warrant a retraction:

Considering that both articles were published over a decade ago and both have been referenced by other papers over a dozen times each, it seems like a retraction of one manuscript may damage the integrity of the literature more than using the erratum to point out the error to future scientists.

The study, “In vitro shoot regeneration from cotyledonary node explants of a multipurpose leguminous tree, Pterocarpus marsupium roxb,” developed a protocol for effectively growing shoots of the Indian Kino tree.

The first version has been cited 21 times and the duplicated version was cited 13 times, according to Thomson Scientific’s Web of Knowledge. Here’s the notice:

Oregon grad student admits to faking data in four neuroscience papers

oriweb_logoA graduate student at the University of Oregon in Eugene has admitted to faking data that appeared in four published papers in the field of visual working memory, according to the Office of Research Integrity.

David Anderson’s supervisor at the time was Edward Awh, who has since moved to the University of Chicago.

Anderson told Retraction Watch that the misconduct stemmed from “an error in judgment”:
