The story of Levon Khachigian’s research is a long and winding tale.
One place to start would be in October 2009, when a paper co-authored by Khachigian — whose work at the University of New South Wales (UNSW) has been funded by millions of dollars in funding from the Australian government, and has led to clinical trials, although more on that later — was retracted from Biochemical and Biophysical Research Communications. The “corresponding author published the paper without the full consent or acknowledgement of all the researchers and would like to apologize for this error,” according to that notice. Continue reading An Australian university cleared a cancer researcher of misconduct. He’s now retracted six papers.
The Journal of Biological Chemistry (JBC) has retracted a 2003 paper that resulted from the PhD thesis of Maryanne Demasi, an Australian journalist whose reporting on statins and the risks of cancer from cell phones has been a lightning rod.
The move, for what the journal says was attempts to reuse images to represent different experiments, follows an investigation by the University of Adelaide into allegations of image manipulation in Demasi’s thesis. In the investigation, Demasi
A researcher at the University of Kentucky who studies the cancer risks of toxic chemicals has retracted three papers. All of the retraction notices, which appear in the Journal of Biological Chemistry, refer to some kind of image duplication. The papers were originally published between 2014 and 2017, with the 2014 paper cited 39 times, according to Clarivate Analytics’ Web of Science.
A cancer researcher and emeritus professor at The Ohio State University has retracted four more papers, bringing his total to nine from a single journal.
The four retractions of work by Samson Jacob appear in the Journal of Biological Chemistry, from which Jacob retracted five papers in March. The original papers — one of which has been cited more than 250 times — date back to 2002.
Adeel Safdar was once a rising star in the field of kinesiology. After completing his doctorate degree at McMaster University in Canada, working with one of the titans of his field, Safdar took a postdoc at Harvard, then accepted a newly created chair position at another university in Ontario.
That all came crashing down last year, when Safdar went on trial in Canada, accused of horrifically abusing his wife. Over the course of the trial, allegations arose about his research, prompting two journals to flag papers he co-authored with his former mentor, Mark Tarnopolsky.
A cancer researcher based at The Ohio State University has retracted five papers from one journal, citing concerns about figures.
The notices for all five papers state the Journal of Biological Chemistry raised questions about some figures, and the authors were not able to supply raw data in all instances. Four of the notices say the authors offered to submit data from repeat experiments and corrected figures, which the journal declined.
According to Kaoru Sakabe, data integrity manager at JBC, the authors “agreed to withdraw these articles after we declined their offers.”
Researchers in Australia have withdrawn a 2006 paper in The Journal of Biological Chemistry (JBC), citing image duplication.
In the withdrawal notice, published July 14, 2017, the authors claim that the “errors do not impact the underlying scientific findings of the article.”
Although the notice does not mention an investigation, a comment on PubPeer on March 2017—signed by Mark Hargreaves, the vice-chancellor at the University of Melbourne—indicates that the university conducted an investigation to assess the issues in the paper and determined that research misconduct “did not occur.”
