“I kind of like that about science:” Harvard diabetes breakthrough muddied by two new papers

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

Weekend reads: Scientists behaving badly; sexual harassment at Yale; help us find Retraction Watch bugs

First, a housekeeping note: We migrated web hosts this week, and while the move seems to have gone mostly smoothly, we’ve noticed a few issues: Comments aren’t threaded (even though we have them set up to be), categories aren’t properly nesting, and a small percentage of comments didn’t transfer over with the rest, the way they should have. We’re working on getting this resolved, and looking into whether we can (or should) restore upvoting and downvoting on comments, so please let us know of any other issues you see, and thanks as always for your patience.

Here’s what was happening elsewhere: Continue reading Weekend reads: Scientists behaving badly; sexual harassment at Yale; help us find Retraction Watch bugs

Kidney journal pulls abstract for author issues

Nephrology Dialysis Transplantation has retracted a 2014 meeting abstract by a group of researchers on Crete whose ranks were inflated by one.

The abstract, titled “GENOTYPE (A) OF ENOS GENE AND R229Q MUTATION OF NPHS2 APPEARS TO BE ASSOCIATED WITH A WORSE OUTCOME IN PATIENTS WITH IGA NEPHROPATHY,” was presented at the European Renal Association-European Dialysis Association’s annual meeting.

Here’s what it reported: Continue reading Kidney journal pulls abstract for author issues

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

Molecules 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

A 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

Cardiovascular 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

Is 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
