MD Anderson postdoc faked results of Novartis anti-cancer compound study

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:

UT-Southwestern cancer research group notches ninth retraction

A research team at the University of Texas-Southwestern that has retracted eight papers for image manipulation has retracted another, this one in Lung Cancer.

Here’s the notice for “Aberrant methylation of Reprimo in lung cancer,” published by Adi Gazdar’s group: Continue reading UT-Southwestern cancer research group notches ninth retraction

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

A 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

Mega-correction appears for Florida leadership scholar Walumbwa following six retractions

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:

“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

ORI sanctions collaborator of Nobel winner Buck for data fabrication

The Office of Research Integrity has sanctioned a former researcher in the lab of Linda Buck, winner of the 2004 Nobel Prize in Physiology or Medicine, for falsifying data in two papers written with the support of grants from the National Institutes of Health.

The researcher, Zou Zhihua, worked with Buck as a post-doc at Harvard and then at the Fred Hutchinson Cancer Research Center, in Seattle, Buck’s current home. After leaving there in 2005, he spent three years at the University of Texas Medical Branch in Galveston, and now appears to be a faculty member at Jilin University in China.

According to the report:

Paper about widely touted but unapproved “cure” for cancer, autism retracted

A paper about a protein being used — unapproved by health agencies — to treat diseases including cancer and autism has been retracted.

Here’s the notice from the International Journal of Cancer about a 2007 paper purporting to show that the substance, GcMAF, is useful against breast cancer: Continue reading Paper about widely touted but unapproved “cure” for cancer, autism retracted

Incorrect analysis leads to Nature’s sixth retraction in 2014

In what seems to be an example of researchers swiftly and transparently correcting the literature, and acknowledging errors, a pair of scientists have retracted a 2013 paper from Nature.

Here’s the retraction notice for “Genomic organization of human transcription initiation complexes,” by Bryan Venters and Frank Pugh: Continue reading Incorrect analysis leads to Nature’s sixth retraction in 2014

U.S. senator appears to have plagiarized his master’s thesis

A Democratic senator from Montana, John Walsh, is the latest high-profile politician to face plagiarism charges.

The New York Times reports:

…one of the highest-profile credentials of Mr. Walsh’s 33-year military career appears to have been improperly attained. An examination of the final paper required for Mr. Walsh’s master’s degree from the United States Army War College indicates the senator appropriated at least a quarter of his thesis on American Middle East policy from other authors’ works, with no attribution.

In an infographic, the Times lays out the overlapping passages: Continue reading U.S. senator appears to have plagiarized his master’s thesis
