PLOS ONE retraction notice blames deceased author for image manipulation

A 2011 paper in PLOS ONE has been retracted due to “inappropriately assembled” images. The issues, which were highlighted in a correction in TK, are attributed to the corresponding author, Paola Palozza, who has since passed away.

Here’s the notice for “Lycopene Inhibits NF-kB-Mediated IL-8 Expression and Changes Redox and PPARγ Signalling in Cigarette Smoke–Stimulated Macrophages,” which has been cited 33 times, according to Thomson Scientific’s Web of Knowledge: Continue reading PLOS ONE retraction notice blames deceased author for image manipulation

Anesthesiologist “con man” apologizes for faking cover-up charges against Australian university

It’s not uncommon for scientists accused of wrongdoing — especially if they’re fired for it — to attempt to muddy the waters by claiming that they are being framed because they had threatened to blow the whistle on others.  Some of those stories have more than a grain of truth to them.

Here’s one that doesn’t.

Paul Barach, an anesthesiologist who accused his former employer, the University of New South Wales, of a massive cover-up — and in turn accused by his employer of being an academic grifter — has admitted making up the affair.

The Australian, which broke the story, says Barach — a U.S.-born physician — has apologized for making the claims. According to an earlier article in the paper:

Panel says BMJ was right to not retract two disputed statin papers

bmjA panel reviewing The BMJ‘s handling of two controversial statin papers said the journal didn’t err when it corrected, rather than retracted, the articles.

The articles — a research paper and a commentary — suggested that use of statins in people at low risk for cardiovascular disease could be doing far more harm than good. Both articles inaccurately cited a study that provided data important to their conclusions — an error pointed out vigorously by a British researcher, Rory Collins, who demanded that the journal pull the pieces.

In a letter to Godlee this spring, Collins wrote: Continue reading Panel says BMJ was right to not retract two disputed statin papers

Another Nature stem cell paper is retracted

nature 73014Another stem cell paper has been retracted from Nature, this one a highly cited 2008 study that had already been the subject of what the journal’s news section called a “furore” in 2010.

According to that 2010 news story:

The researchers behind the original work1, led by Thomas Skutella of the University of Tübingen, reported using cells from adult human testes to create pluripotent stem cells with similar properties to embryonic stem cells.

But a 2010 Brief Communication Arising called those findings into question. And now, the authors have retracted the paper. Here’s the notice for “Generation of pluripotent stem cells from adult human testis:” Continue reading Another Nature stem cell paper is retracted

Raymond Sawaya, director of MD Anderson’s brain tumor program, presents Jun Fu with the 2014 Caroline Ross Endowment Fellowship.

A former postdoc at MD Anderson Cancer Center faked the results of a mouse study of a Novartis compound designed to fight brain tumors, according to the Office of Research Integrity (ORI).

Jun Fu “admitted to knowingly and intentionally falsifying Figure 8a” in “Novel HSP90 Inhibitor NVP-HSP990 Targets Cell-Cycle Regulators to Ablate Olig2-Positive Glioma Tumor–Initiating Cells,” a paper published in Cancer Research on May 15, 2013:

Authors retract paper “confirming” that narcolepsy is an autoimmune disease

stmA group of researchers at Stanford and elsewhere is retracting a 2013 paper that another scientist told Nature was “one of the biggest things to happen in the narcolepsy field for some time.”

The Science Translational Medicine paper caused a buzz because it claimed to show that narcolepsy was an autoimmune disease. Here’s the notice: Continue reading Authors retract paper “confirming” that narcolepsy is an autoimmune disease

Fred Walumbwa, the leadership researcher at Florida International University who has retracted six papers for what appear to be problematic data, now has an impressive mega-correction in the form of an “addendum.”

The paper, “Relationships between Authentic Leadership, Moral Courage, and Ethical and Pro-Social Behaviors,” was published in Business Ethics Quarterly in October 2011, by Walumbwa and two colleagues, Sean Hannah and Bruce Avolio.

Here’s the abstract for the paper, which has been cited 18 times, according to Thomson Scientific’s Web of Knowledge:

“Authors, please call us. Pretty please? OK, we’re going to retract your paper!”

dovelogoThe title of this post isn’t exactly how the one-sided conversation between the editors of Neuropsychiatric Disease and Treatment and a group of researchers went. But it seems likely it was pretty close.

Here’s an expression of concern for “A cross-sectional study on perception of stigma by Chinese schizophrenia patients:” Continue reading “Authors, please call us. Pretty please? OK, we’re going to retract your paper!”

“Positivity ratio” research now subject to an expression of concern

An expression of concern has been issued for the second of three papers on the idea that, if you have three positive emotions for every negative one, you will be more successful in life.

Psychologist Barbara Fredrickson, of the University of North Carolina, Chapel Hill, has spent the last decade building a brand around this ratio, initially described by a mathematical equation based on fluid dynamics by mathematician Marcial Losada. You can read our coverage of the debunking of that equation, presented in a 1999 paper that has been cited nearly 1,700 times, here.

Nick Brown, co-author with Alan Sokal on the paper that discredited the Losada equation, has written a blog post on the current state of affairs. He also got in touch with us regarding the expression of concern for a 2004 article in American Behavioral Scientist that he had also questioned, “The Role of Positivity and Connectivity in the Performance of Business Teams: A Nonlinear Dynamic Model”: Continue reading “Positivity ratio” research now subject to an expression of concern
