Another retraction from University of Waterloo, this time for duplication

Canada’s University of Waterloo is racking up the retractions, with one in July for plagiarism, another earlier this month for faked data from a graduate student who had her master’s degree revoked, and now a third for duplication.

Here’s the notice, for “The influence of friends, family, and older peers on smoking among elementary school students: Low-risk students in high-risk schools,” which appeared in Preventive Medicine in March 2006: Continue reading Another retraction from University of Waterloo, this time for duplication

Update: Data fabricator had masters’ degree revoked

On Friday, we reported on the case of a retraction in the American Journal of Physiology — Cell Physiology by kinesiology researchers at Canada’s University of Waterloo for data fabrication by a graduate student, Sara Michelle Norris. We heard back from Waterloo yesterday, and have more details.

In our Friday post, we wondered whether Norris’s 2009 masters’ thesis,“Contribution of Sarcoplasmic Reticulum Calcium Pumping to Resting Mouse Muscle Metabolism,” might have been compromised. Waterloo tells us Norris is no longer at the university: Continue reading Update: Data fabricator had masters’ degree revoked

Data fabrication fells muscle physiology paper

Kinesiology researchers at the University of Waterloo in Canada have been forced to retract a 2010 paper in the American Journal of Physiology — Cell Physiology in the wake of revelations that the first author, then a graduate student, fabricated her data.

The paper, “ATP consumption by sarcoplasmic reticulum Ca2+ pumps accounts for 50% of resting metabolic rate in mouse fast and slow twitch skeletal muscle,” was written by Sarah Michelle Norris and colleagues and published in March 2010.

According to the retraction notice: Continue reading Data fabrication fells muscle physiology paper

ORI investigating University of Florida ob-gyn researcher accused of misconduct

A prominent researcher at the University of Florida is under federal investigation for research misconduct and has lost at least one paper as a result of the fraud.

The researcher, Nasser Chegini, was a professor of obstetrics and gynecology at the U of Florida until about six months ago, when he retired, according to the chair’s office. Nasser has received at least $4 million in federal grant funding, according to the university.

The retracted paper, “MicroRNA 21: response to hormonal therapies and regulatory function in leiomyoma, transformed leiomyoma and leiomyosarcoma cells,” was published in 2010 by Molecular Human Reproduction. The authors were Qun Pan and Xiaoping Luo and Chegini.

Another retraction for Anil Potti, with an inscrutable notice

We’ve seen a lot of retraction notices for work by Anil Potti — 10, to be precise, along with 7 corrections and one partial retraction notice. As notices go, they tend to be pretty complete. So when we saw one in CHEST for this 2008 abstract, we were expecting something similar.

Instead, we were confused.

Here’s the notice: Continue reading Another retraction for Anil Potti, with an inscrutable notice

JAMA’s first-ever Expression of Concern appears for hip protector study

JAMA has issued its first-ever Expression of Concern over a 2007 study of hip protectors in the elderly that came under scrutiny from Federal regulators.

As the Boston Globe was first to report yesterday, the journal’s editor and executive deputy editor wrote in a notice published online: Continue reading JAMA’s first-ever Expression of Concern appears for hip protector study

Former Harvard psychology prof Marc Hauser committed misconduct in four NIH grants: ORI

Two years after questions surfaced about work by former Harvard psychology professor Marc Hauser, an official government report is finally out.

It’s not pretty.

The findings by the Office of Research Integrity were first reported by the Boston Globe, which was also first to report the issues in Hauser’s work. They’re extensive, covering misconduct in four different NIH grants (we’ve added some links for context): Continue reading Former Harvard psychology prof Marc Hauser committed misconduct in four NIH grants: ORI

ORI finds Harvard stem cell lab post-doc Mayack manipulated images

Shane Mayack, a former post-doc in Harvard lab of Amy Wagers, a rising star in the stem cell field, has been sanctioned by the Office of Research Integrity for misconduct.

Mayack, who has defended her actions on this blog as honest error — albeit sloppiness — and has not admitted to wrongdoing, must undergo supervision if she receives any federal grant funding over the next three years, under the voluntary agreement.

Here’s the notice, which appeared in the Federal Register this week (and which the Boston Globe was first to report): Continue reading ORI finds Harvard stem cell lab post-doc Mayack manipulated images

Hypertension retracts paper over data glitch

The anticipation of having one’s blood pressure measured can cause it to spike.

So, evidently, can errors in data processing — on a national scale.

Hypertension, a journal published by the American Heart Association, has retracted a 2011 paper looking at the implications of blood pressure management guidelines after the authors discovered they had bungled the merging of their data files.

As the notice explains: Continue reading Hypertension retracts paper over data glitch

Plagiarism costs Canadian lab-on-a-chip researcher a paper — in his own journal

We have long (well, for the past two years) wondered about the pitfalls of publishing in one’s own journal, and here’s a case that illustrates precisely how fraught that practice can be.

The journal Microfluidics and Nanofluidics has retracted a 2010 article, titled “Induced-charge electrokinetic phenomena,” by Dongqing Li and Yasaman Daghighi, of the University of Waterloo in Canada, for what appears to be extensive misappropriation of text and data.
