A group of cancer researchers in Mexico has lost their third paper over concerns about the integrity of their data.
Neither the new retraction, in the journal Hematology, nor the previous two, cite misconduct as the reason for the removals. However, the statements do refer to lack of reliability of results, “ambiguities and inconsistencies” in the findings and other serious issues.
The first author on each paper is Agustin Avilés, whom the Hematology article listed as being with the National Medical Center in Mexico City.
It started as a simple email exchange over authorship. But it angered one researcher so much that it ended a 20-year collaboration.
In January 2017, a chemist based in Mexico had finished writing a paper describing the structure of a molecule. Sylvain Bernès, at the Instituto de Física Luis Rivera Terrazas, asked his co-author—the head of the lab where the molecule had been synthesized 10 years ago—to review the draft and include any co-authors involved in the initial work.
Check List, the “journal of species lists and distribution,” retracted a paper in February after the authors realized they hadn’t spotted a yellow-red rat snake in a strange range, but rather a green rat snake in its known home.
Alejandra Bravo and Mario Soberon, a wife-husband research team at the National Autonomous University of Mexico (UNAM) who received sanctions — later lifted — for manipulating images in a number of papers have corrected another article.
Last November we wrote about the case of Alejandra Bravo and Mario Soberón, a wife-husband team of microbiologists studying genetically modified crops, who had been disciplined by the National Autonomous University of Mexico for having manipulated images in 11 papers.
