Paolo Macchiarini — once a world-renowned surgeon for creating tracheas from cadavers and patients’ own stem cells – has been dogged for years by accusations of misconduct. Officials at his institution, Karolinska Institute, initially cleared him of many charges, but that all changed earlier this year, when Swedish Television (SVT) aired a series of documentaries about Macchiarini and his work. The series alleged, in part, that he operated on patients in Russia whose conditions were not life-threatening enough to warrant such a risky procedure. Such serious accusations caused a media storm, and prompted officials to take a second look at Macchiarini’s work. KI dismissed Macchiarini, and many others have resigned, including KI’s vice chancellor. Recently, two new reports critiqued KI’s role in the case, and Sweden’s Central Ethical Review Board found Macchiarini guilty of misconduct in a 2014 paper. We spoke with SVT producers Bosse Lindquist and Johannes Hallbom via email about the fallout from their series.
A Copenhagen court has cleared neuroscientist Milena Penkowa of the most serious charges against her after she appealed a 2015 verdict that she had faked data.
According to the CPH Post, the Eastern High Court in Copenhagen dismissed the case. Although the court acknowledged she had committed fraud, it declared it was not “serious forgery.”
Institutions in France and Switzerland are investigating figures in several molecular biology papers, according to a joint press release published today.
Unfortunately, there’s not much more we can tell you about the investigation — the press release doesn’t specify the names of researchers, journals, or even the area within molecular biology that’s under scrutiny.
The National Center for Scientific Research (CNRS) in France will lead the inquiry, with contribution from ETH Zürich in Switzerland. Molecular biology researchers from both institutions were involved in the flagged publications, an ETH Zürich spokesperson told us.
A cancer researcher has added a fifth retraction to his name — but the notice doesn’t mention any problems with the paper itself.
Rather, the Journal of Mammary Gland Biology and Neoplasia decided to retract the paper because it referenced other papers that had been retracted as a result of data manipulation.
The notice doesn’t specify which references were problematic, but the list includes three papers that are now retracted; all three include Scott Valastyan (the sole author of the newly retracted paper) as first author, and two list Robert Weinberg, his former supervisor and prominent cancer researcher, as last author.
A nutrition researcher with multiple retractions who unsuccessfully sued the Canadian Broadcasting Corporation (CBC) for libel has been charged with defrauding a state health insurance plan.
A cancer researcher who tried to sue PubPeer commenters for criticizing his work has earned five more retractions, bringing his total to 18.
All of the new retractions for Fazlul Sarkar, formerly based at Wayne State University in Michigan, appear in the International Journal of Cancer. Allcite an institutional investigation, and relate to issues with images.
With 18 retractions, Sarkar has now earned a spot on our leaderboard.
We first encountered Sarkar when he subpoenaed PubPeer to reveal the names of anonymous commenters that potentially cost him a job at the University of Mississippi. Earlier this month, a Wayne State spokesperson confirmed to us that Sarkar has now retired from the university. (To get up to speed, check out our timeline on the major events in this case.)
Fazlul Sarkar has not had a good month: In the last few weeks, he has earned 13 retractions across four journals, the latest in the fallout from a string of legal cases that have pitted him against one of science publishing’s major players.
Sarkar gained attention in 2014 when he sued anonymous commenters of PubPeer for defamation, and for potentially costing him a new gig at the University of Mississippi. But before all that, he was a respected researcher with hundreds of published papers, 38 of which were cited at least 100 times each. He’d also received $12.8 million in NIH funding for his research. So how did it all fall apart?
A cancer researcher has earned seven more retractions following an investigation into his work by his former employer, MD Anderson Cancer Center in Texas, bringing his total to 18 retractions.
All of the new retraction notices, issued by The Journal of Biological Chemistry (JBC), stem from image-related issues. The now-retired Aggarwal has seven papers that have each been cited at least 1,000 times, and in 2015, he was on Thomson Reuters Web of Science’s list of The World’s Most Influential Scientific Minds. With these new notices, he also has made it to our leaderboard of individual researchers who’ve racked up the most retractions.
