Group’s duplication retractions span the globe, from New Zealand to Romania to Croatia

The retraction count continues to grow for a group of Iranian scientists who appear to have published similar work four times.

Researcher logs three retractions for image duplications — two of which with familiar co-authors

A researcher in Brazil is taking responsibility for accidentally mixing up images in three papers in the Journal of Biological Chemistry.  The corresponding author on the three papers told us the mistake happened because the studies were conducted simultaneously, and relied on one computer. There’s a side note to these retractions: The co-author list on … Continue reading Researcher logs three retractions for image duplications — two of which with familiar co-authors

Heart attack: Two cardiology retractions, plus a notice of duplication, in three different journals

We’ve come across three notices in cardiology journals this week, so although they’re unrelated, we’re gathering them here. Item 1, from Circulation Research:

Duplication forces retractions of two 15-year-old entomology papers

A Brazilian entomologist, Claudio Jose von Zuben, has been forced to retract two papers from 1997 after editors became aware that he and his colleagues had used the same figure in both. First, the notice from Memórias do Instituto Oswaldo Cruz:

Gastro journal continues tough stance on duplication, with two new retractions

Monica Acalovschi is serious about ridding the literature of duplicate publications. That would seem to be the message of two new retraction notices in the Journal of Gastrointestinal and Liver Diseases, which Acalovschi edits — two retractions that join another for similar reasons, which we covered earlier this year. Here are the notices, from the … Continue reading Gastro journal continues tough stance on duplication, with two new retractions

Retractions we haven’t had a chance to cover, part 3: Another duplication and plagiarism edition

As more and more journals enroll in CrossCheck, designed to ferret out cases of plagiarism, it’s to be expected that the number of papers retracted for copying and pasting will increase. Sometimes, that plagiarism is actually duplication of material that the same authors have published elsewhere, while other times it’s good old-fashioned plagiarism of someone … Continue reading Retractions we haven’t had a chance to cover, part 3: Another duplication and plagiarism edition
