Doug Melton

Harvard stem cell researcher Doug Melton got a lot of press last year for research on a hormone he named betatrophin, after its supposed ability to increase production of beta cells, which regulate insulin.

Now, the conclusions from that paper, which has been cited 59 times, according to Thomson Scientific’s Web of Knowledge, have been called into question by research from an independent group, as well as follow-up work from the original team.

The interest was driven by the hormone’s potential as a new treatment for diabetes. In 2013, Melton told the Harvard Gazette that betatrophin could be in clinical trials within three to five years. Here’s Kerry Grens in The Scientist: Continue reading “I kind of like that about science:” Harvard diabetes breakthrough muddied by two new papers

Kidney journal pulls abstract for author issues

A tale of two notices as Tunisian chemists lose two papers for duplicated data

molecules-logoMolecules has pulled a 2010 article by a trio of chemists from Tunisia who tried — and succeeded, for a while, at least — to publish the same data twice. The article was titled “An Expeditious Synthesis of [1,2]Isoxazolidin-5-ones and [1,2]Oxazin-6-ones from Functional Allyl Bromide Derivatives.” And indeed it was expeditious. Here’s the notice: Continue reading A tale of two notices as Tunisian chemists lose two papers for duplicated data

University of Utah investigation fingers chem engineering grad student for misconduct

acs nanoA second retraction has been issued in a case of research misconduct at the chemistry department of chemical engineering at the University of Utah.

The first retraction, in August of 2013, got a lot of attention for how poorly faked the figures were. At the time, an expression of concern was issued on the paper that has just been retracted.

Today, we exchanged emails with Jeffery Botkin, the research integrity officer at the University of Utah, who ran the investigation into the misconduct. He summarized the report for us below. Continue reading University of Utah investigation fingers chem engineering grad student for misconduct

Heart journal pulls paper for image manipulation

cardresCardiovascular Research has retracted a 2010 paper by a group of prominent cardiology researchers in Brazil.

The reason: Image manipulation — which the authors say didn’t materially affect the conclusions of the paper.

The article, “FAK mediates the activation of cardiac fibroblasts induced by mechanical stress through regulation of the mTOR complex,” came from a group led by Ana Paula Dalla Costa, from the State University of Campinas.

Here’s the abstract of the study, which has been cited 19 times, according to Thomson Scientific’s Web of Knowledge: Continue reading Heart journal pulls paper for image manipulation

“Embarrassing and regrettable incident of faulty memory” leads to retraction

aaaIs there any accounting for plagiarism?

A set of educational materials for accounting classes has been retracted for plagiarizing work published a decade earlier.

We spoke to the author of the retracted work, who explained that over the course of ten years of revising his classroom material, he lost track of what was original, and what was written by him or his fellow University of Saskatchewan professors.

Here’s the notice for “Ramm Wholesale: Reviewing Audit Work”: Continue reading “Embarrassing and regrettable incident of faulty memory” leads to retraction

Asking for a retraction was “an overbearing response, though I agree that the student screwed up big time”

celluloseJust two months after a PhD student at King Fahd University of Petroleum and Minerals in Saudi Arabia published a paper in August without the knowledge of his co-author, a professor at the university, the paper was retracted by Cellulose.

Here’s the notice for “Corrosion protection of steel sheets by chitosan from shrimp shells at acid pH,” by graduate student Ubong M. Eduok and professor Mazen M. Khaled (well, not really by Khaled): Continue reading Asking for a retraction was “an overbearing response, though I agree that the student screwed up big time”
