Three more retractions for Vietnamese physicists who plagiarized a plagiarized paper

Last week, we brought you the story of Thong Duc Le and his colleagues, physicists who were forced to retract four papers, including one that cited, as we noted “their own study that had already been retracted for plagiarism.”

The team has now retracted three more papers:

Astrophysics retraction trail includes paper that plagiarized another already retracted for…plagiarism

Sometimes, the full story of scientific misdeeds isn’t clear until several retraction notices appear. Take the case of a group of Vietnamese astrophysicists led by Thong Duc Le.
