Nutrition researcher Chandra loses libel case against CBC

CBCThe self-proclaimed “father of nutritional immunology,” Ranjit Kumar Chandra, has lost a libel lawsuit against the Canadian Broadcasting Company (CBC).

The suit was in response to a 2006 three-part documentary from the CBC, which examined allegations of fraud against the former Memorial University researcher.

After the 58-day trial, the Ontario Superior Court of Justice “ruled in favour of CBC, on the grounds that the words in the broadcast were true,” according to CBC producer Lynn Burgess: Continue reading Nutrition researcher Chandra loses libel case against CBC

Head of major diagnostic lab in Canada steps down amid investigation

AJPA_v185_i7_COVER.inddA prominent endocrinologist pathologist has resigned from running the largest hospital diagnostic laboratory in Canada following an investigation that has uncovered evidence of falsified data in two papers, Retraction Watch has learned.

Sylvia Asa was the Program Medical Director of the Laboratory Medicine Program at the University Health Network, affiliated with the University of Toronto, until this past spring when she stepped down, according to UHN spokesperson Gillian Howard:

Psych journal axes study of child molesters

Journal Of Sexual Aggression

A journal has issued a “notice of redundant publication” for a paper that used virtual reality to understand arousal patterns in child molesters — the result of “an unfortunate sequence of personal events relating to the first author.”

The study, “Using immersive virtual reality and ecological psychology to probe into child molesters’ phenomenology,” was originally published online in 2011 and printed in 2013.

The Journal of Sexual Aggression announced the “notice of redundant publication” after the editors discovered the article contained “content of which much was included in an article published between the first online publication date of the original article and the final publication”. The article shares many of the same co-authors, and has since been retracted.

Patrice Renaud, the first author and a lecturer at the University of Quebec in Outaouais, took responsibility for the additional publications. In an email to Retraction Watch, Renaud said that the issues arose because of a family medical emergency:

Asphalt paper paved over for allegedly plagiarizing a student’s thesis

PSTThe publishers of the journal Petroleum Science and Technology have retracted a paper because one of the authors “did not agree to co-author this manuscript,” and did not even communicate with the other three authors.

According to one involved party, the problem is bigger than just lack of communication: The paper, “Fatigue and Low Temperature Fracture in Bitumen Mastic,” authored by a dean of civil engineering in Iran, was “copied word for word” from a Canadian student’s master thesis, according to the student’s advisor.

Three of the authors on the paper are engineers at the Shahid Rajaee Teacher Training University in Tehran, Iran, including the dean of civil engineering, Saeed Ghaffarpour Jahromi. The fourth author, B. J. Smith, is listed as a member of the Department of Chemistry at Queen’s University in Kingston, Ontario.

Duplication snuffs out pollen abstract

AACIA Canadian research team has retracted a meeting abstract “published in error” from a supplement by Allergy, Asthma & Clinical Immunology, as it had previously been published in another journal.

The December 2014 abstract, “A post-hoc qualitative analysis of real time heads-up pollen counting versus traditional microscopy counting in the environmental exposure unit (EEU),” describes a custom digital imaging method for counting pollen in real-time. The abstract was published ten months earlier, in February 2014, under the same title in the Journal of Allergy and Clinical Immunology.

Here is the full retraction note:

Cancer team loses two papers for image manipulation

bba_2A team spread across multiple institutions in China and McGill University in Canada has retracted two cancer papers over “inaccurate and inappropriately processed Western Blots.”

Some of the figures were also reused between the two articles, both in Biochimica et Biophysica Acta General Subjects.

The articles both tested the cancer-fighting properties of a derivative of the active compound present in Boswellia serrata gum resin.

Stats mistake crashes bike accident paper

Two researchers at the University of Saskatchewan in Canada have retracted a paper that came to fairly common-sense conclusions about bike safety.

In the September 2014 issue of the Journal of Transport and Health, the authors concluded that slippery road surfaces, night-time biking, and higher speed limits were all associated with higher probabilities of a bicycle accident.

Despite these logical conclusions, the authors discovered a statistical error that “would significantly change the discussion,” according to the retraction notice.

Authors get away with throwing quotation marks around plagiarized passages. Again.

PNAS jan15Back in November 2013, we wrote about a correction in PNAS about a May 2012 paper by a group from Toronto and Mount Sinai in New York who, as we said at the time

had been rather too liberal in their use of text from a previously published paper by another researcher — what we might call plagiarism, in a less charitable mood.

Fat cell paper earns unusually detailed retraction

jcbA pair of cell biologists have taken responsibility for extensive figure errors that scuttled their paper in the Journal of Cell Biology.

While there were five authors, first and last authors Eva Szabo and Michal Opas took responsibility in the notice. A number of figures “contain incorrect data and/or presentation errors,” and the original data isn’t available for verification. The notice is unusually clear about which figures and data are compromised.

The paper was published in 2008, and retracted on January 12, 2015. It has been cited 32 times, according to Thomson Scientific’s Web of Knowledge.

Geothermal paper undermined by borrowing data without citing

rsesAn international group of engineers lost a paper in November after the journal realized the majority of the data came from a government assessment of Australia’s energy resources without a citation.

The paper, published in Renewable and Sustainable Energy Reviews, focused on geothermal energy, while the government report was far broader in scope. However, the lack of independent research was enough to sink the review. We covered another Renewable and Sustainable Energy Reviews retraction recently, making us wonder if this is part of a crack-down for the journal.

Here’s the notice for “A review of geothermal energy resources in Australia: Current status and prospects”: Continue reading Geothermal paper undermined by borrowing data without citing
