Wham, bam, no thank you, ram: Publisher error leads to retraction of already-withdrawn sheep sperm paper

Caution: Sexual innuendo ahead.

The withdrawal method is a notoriously unreliable form of birth control. It seems that what happens between the sheets applies to paper as well as cotton.

Here’s a retraction notice from BMC Research Notes that speaks — and nudges and winks — for itself. The 2011 article, “Effect of controlled and uncontrolled cooling rate on motility parameters of cryopreserved ram spermatozoa,” by a team of Irani veterinary scientists: Continue reading Wham, bam, no thank you, ram: Publisher error leads to retraction of already-withdrawn sheep sperm paper

Is post-hoc statistical analysis the new fraud detection tool? A new review looks at fraudster Reuben’s work

In the beginning, there was Scott Reuben.

Well, not quite. Reuben, a Massachusetts anesthesiologist who fabricated data and briefly topped our list of most-retracted authors, didn’t invent research fraud, although he did spend six months in federal prison for his crimes. But his case was in no small measure responsible for the birth of this blog, and, well, the rest of human history that followed.

Although Reuben’s retractions are behind him now — his count ends at 22 — and other scientists, including two anesthesiologists, Joachim Boldt and Yoshitaka Fujii, have or likely soon will dramatically eclipsed his mark, a new paper has revisited his publications with an eye toward seeing if they could identify statistical evidence of data manipulation. It’s the same  kind of effort that Ed Yong highlighted as noteworthy about the Dirk Smeesters case, which we covered yesterday and which involved an anonymous statistically inclined whistleblower.

Before we get to whether there was evidence of such manipulation Continue reading Is post-hoc statistical analysis the new fraud detection tool? A new review looks at fraudster Reuben’s work

Misconduct burns authors of wax paper, leads to sharply worded retraction notice

Philosophical Transactions of the Royal Society A is retracting a 2010 paper whose authors misappropriated data, forged an author name — and got a pretty strong backhand slap for the trouble.

The paper, “Green waxes, adhesives and lubricants,” which refers to eco-friendly materials, not Halloween-friendly slimes, was published by a group of researchers from China and Canada. Problem was, the one from Canada evidently didn’t know she was listed on the manuscript, and a big chunk of the work had been misappropriated from her university.

As the notice explains: Continue reading Misconduct burns authors of wax paper, leads to sharply worded retraction notice

JPET peeves: Paper withdrawn after drug company won’t disclose chemical structure

A group of researchers at the drug company ChemoCentryx is withdrawing a 2012 paper in the Journal of Pharmacology and Experimental Therapeutics over failure to appropriately identify the molecule they describe in the article.

The withdrawal notice tells the story: Continue reading JPET peeves: Paper withdrawn after drug company won’t disclose chemical structure

Three more Fujii papers fall for lack of IRB approval

Three journals under the JAMA umbrella are retracting papers by Yoshitaka Fujii, the Japanese anesthesiologist accused of research misconduct so sweeping that it might net him the record for most retractions by a single author.

The papers, in the Archives of Surgery, Archives of Ophthalmology and the Archives of Otolaryngology — Head & Neck Surgery, were published in 2001 and 2005.

Here are the notices, which are essentially identical but for the titles of the articles: Continue reading Three more Fujii papers fall for lack of IRB approval

Resveratrol researcher Das in video: Yes, I manipulated images, but only because the journals asked me to

Das, via UConn

Dipak Das, who until earlier this year ran a high-profile cardiovascular research center at the University of Connecticut, has recorded a slick looking video defense against allegations that he cooked data and manipulated images in scores of published studies, 12 of which have been retracted to date.

Das, who was hit with a 60,000 pages of allegations stemming from a three-year investigation by the university, spends the bulk of the documentary-style interview — which is available on YouTube — talking about the wonders of resveretrol. But he gets into the misconduct charges at about the 15-minute mark.

PLoS ONE expresses concern over flu vaccine paper

PLoS ONE has issued an expression of concern over a  2010 paper by Chinese scientists about how the immune system responds to the vaccine against the swine flu.

The article, “Protection Induced on Day 10 Following Administration of the 2009 A/H1N1 Pandemic Influenza Vaccine,” claimed to study 58 subjects given the inoculation (more on that below) and that Continue reading PLoS ONE expresses concern over flu vaccine paper

Tell-tale hearts: Cardiology journals retract redundant articles

The European Journal of Cardiothoracic Surgery has retracted a 2007 article by Chinese researchers after the senior author decided he liked the data so nice he’d publish them twice. And he appears to have done so without the knowledge of the corresponding author.

Here’s the notice for the paper, titled “Open-heart surgery in patients with liver cirrhosis”: Continue reading Tell-tale hearts: Cardiology journals retract redundant articles

Circulation retracts four papers by author who misled on IRB approval

Circulation has retracted four articles by a pediatric cardiologist in Japan who failed to obtain ethics approval for the studies in question but evidently lied about it to the journal.

The researcher, Hideaki Senzaki, of Saitama Medical University, is a highly-published investigator who trained for a time with at Johns Hopkins.

According to the Circulation notice: Continue reading Circulation retracts four papers by author who misled on IRB approval

Chemist Craig Hill, author of JACS and Science papers, explains the retractions

Last week, we reported that Craig Hill, a prominent chemist at Emory University, and his colleagues at six other institutions are retracting three papers they published in the mid-2000s, two in the Journal of the American Chemical Society and one in Science.

We have now spoken with Hill, who walked us through the history of the research. According to Hill, the international team of researchers, after “unusually extensive experiments” felt they had enough evidence to publish their original articles

but all authors (and others) remained skeptical given the unprecedented nature of these compounds.

Hill’s lab continued to conduct experiments and probe the original data after the publications, he said. (Hill wrote a piece for Nature in 2008 explaining the significance of the research, which, among other things, might lead to better ways of harnessing solar energy.)
