Parkinson’s researcher Caroline Barwood pleaded not guilty to fraud-related charges in a Brisbane courtroom Monday.

According to 9News, Barwood is accused of three counts of fraud, and four instances of attempted fraud, which include trying to obtain approximately $700,000 (AUD) from various organizations between 2011 and 2013 for a study that never occurred. The case follows an investigation at her former institution, the University of Queensland (UQ), which resulted in three of her papers being retracted. 

Crown Prosecutor Caroline Marco alleged that Barwood was also intimately involved with Bruce Murdoch, her former colleague at the UQ, who has pleaded guilty to 17-fraud related charges, and received a two-year suspended sentence earlier this year.

Marco also claimed that Barwood admitted that Continue reading Parkinson’s researcher in Australia pleads not guilty to fraud

Macchiarini paper in Nature journal earns expression of concern for data questions

nature-communications-228x300Nature Communications has issued an expression of concern for a 2014 paper by beleaguered surgeon Paolo Macchiarini, citing concerns over whether the paper accurately reports the experiments that were carried out.

According to the notice, Macchiarini, a former rising star in the field of transplant medicine, agrees with the expression of concern. Three of his 22 co-authors have objected.

“Experimental orthotopic transplantation of a tissue-engineered oesophagus in rats” describes transplanting an esophagus into rats that was seeded with their own stem cells, and notes that all animals survived the study period (14 days), and gained more weight than rats given a placebo operation. It’s a topic Macchiarini has made famous, as the first surgeon to perform a similar procedure with a human tracheal transplant. But he’s faced charges of misconduct in the last few years, resulting in his dismissal from Karolinska Institutet (KI).

Here’s the text of the notice, scheduled to go live at 10 a.m. UK time today: Continue reading Macchiarini paper in Nature journal earns expression of concern for data questions

Cancer researcher earns 5th retraction after misconduct finding

oncoimmunologyA cancer researcher has logged her fifth retraction following an investigation that concluded she had committed scientific misconduct.

We’ve previously reported on four retractions of papers by Stephanie Watkins, a researcher at Loyola Medicine. The previously issued notices — in The Journal of Clinical Investigation and Cancer Research — note that an investigation committee appointed by the National Institutes of Health (NIH) found Watkins to be solely responsible for the misconduct, with none of the co-authors aware of it.

The editor of OncoImmunology previously informed us that the journal was investigating another one of Watkins’ papers; the journal has now pulled that paper, citing “fabrication and falsification of data” in the original studies referenced in the paper.

Here’s the retraction notice, published online earlier this year: Continue reading Cancer researcher earns 5th retraction after misconduct finding

The infractions occurred at The University of Texas Brownsville, which has since become part of The University of Texas Rio Grande Valley (UTRGV). Once the issues were discovered, UTRGV had to make the reimbursements.

On Tuesday, lawyers representing both sides of the ongoing suit filed by a scientist against PubPeer commenters appeared in court, alleging their criticisms of his work cost him a new job at the University of Mississippi.

In the case described as “FAZLUL SARKAR V JOHN DOE,” lawyers representing PubPeer, Sarkar, and the anonymous commenter at the heart of the case spoke before two judges (one was absent). As the case now stands, a judge has ruled that all but one of the commenters can remain anonymous, and PubPeer has filed an appeal, earning the support of the American Civil Liberties Union (ACLU), as well as Google and Twitter.

According to one of the attorneys representing PubPeer, Alex Abdo at the ACLU, things proceeded as expected. Their main argument, he said, was: Continue reading Sarkar vs. John Doe: What happened at this week’s hearing involving PubPeer
