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defense against allegations that he cooked data and manipulated images in scores of published studies, 12 of which have been retracted to date.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.

Catching up: Charges against CFS-XMRV researcher Mikovits dropped, ‘gyres’ author Andrulis publishes another paper

A follow-up on two stories we’ve covered here at Retraction Watch:

1. Criminal charges against chronic fatigue syndrome researcher dropped

The state of Nevada has dropped criminal charges against Judy Mikovits, the embattled chronic fatigue syndrome (CFS) researcher whose paper linking the condition to a virus, XMRV, was retracted last year by Science.

As we reported in November, Mikovits was arrested in Ventura County, California on an “out of county warrant” from Washoe County, Nevada, for allegedly taking lab notebooks, a computer, and other material from the Whittemore Peterson Institute in Reno, Nevada, after the WPI fired her in September.

The first report on the dropped charges was apparently by Mikovits’ friend Lilly Meehan on Facebook, news that was picked up by the ProHealth website on June 13 (their post has since been updated). Later that day, ScienceInsider’s Jon Cohen, who has been covering the case closely, reported that Continue reading Catching up: Charges against CFS-XMRV researcher Mikovits dropped, ‘gyres’ author Andrulis publishes another paper

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

Shikeagi Kato, who resigned post in March, retracts Nature paper

Shikeagi Kato, an endocrinologist formerly of the University of Tokyo who resigned on March 31 amidst an investigation into his work, has retracted another paper, this one in Nature.

Here’s the notice for “DNA demethylation for hormone-induced transcriptional derepression,” which was the subject of a correction last October: Continue reading Shikeagi Kato, who resigned post in March, retracts Nature paper

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.)

Biologists delete paper from literature after realizing they’d deleted too many genes

Researchers deleted more genes than they bargained for in a Drosophila strain, a mistake that resulted in a retraction of a paper from 2007.

Ron Wides, a biologist specializing in pattern development at Bar-Ilan University, Israel, and colleagues have retracted a paper published in Mechanisms of Development after his lab found that their technique to delete the Ten-a gene ended up deleting other nearby genes, too.

It was deletions of other genes, and not Ten-a, that killed the fruit flies, Wides concluded. His group had also concluded, erroneously, that Ten-a is what’s known as a “pair-rule” gene. Fruit fly embryos develop in stacked segments, like tubes of Pringles; pair-rule genes guide the development of alternating segments. Those other loci, and not Ten-a, caused lethality and caused the flies to develop improperly early,  Wides concluded.

Paper claiming hottest 60-year-span in 1,000 years put on hold after being published online

The authors of a study of Australasian temperatures over the past millennium have put the print publication of an online-first study on hold after errors were identified in the records they used.

Here’s how RealClimate.org summarized the findings of the original paper, which was published in mid-May:

The conclusion reached is that summer temperatures in the post-1950 period were warmer than anything else in the last 1000 years at high confidence, and in the last ~400 years at very high confidence.

The page at the American Metereological Society site where the paper used to be now reads: Continue reading Paper claiming hottest 60-year-span in 1,000 years put on hold after being published online

JACS, Science retracting three papers from leading Emory chemist Craig Hill

The Journal of the American Chemical Society (JACS) and Science are retracting three papers by Craig Hill and colleagues which, we’re told, have been the focus of intense scrutiny within the field since they first appeared in the mid-2000. Hill is an internationally renowned expert in catalysis who has won a slew of awards for his work.

JACS has acted first, issuing two notices recently about the papers it published. The first notice, for 2005’s “A Palladium-Oxo Complex. Stabilization of This Proposed Catalytic Intermediate by an Encapsulating Polytungstate Ligand,” states: Continue reading JACS, Science retracting three papers from leading Emory chemist Craig Hill
