Cholesterol paper duplicated; “The authors believed that they had taken the necessary steps to withdraw.”
A review journal is pulling a 2013 article about advances in researchers’ understanding of cholesterol after seeing the same article in another journal.
Although the retracted paper appeared first — online in Biological Reviews in February, 2013 — the journal decided to retract it after learning the authors had initially submitted it elsewhere. The first submission was eventually published (with the exception of one author) in 2014 in Frontiers in Bioscience.
The authors say they “believed that they had taken the necessary steps to withdraw their paper from Frontiers in Bioscience before they submitted to Biological Reviews in June 2012.” Here’s more from the retraction notice:
The authors of a 2015 paper about non-native spider populations in Chile are retracting it from the Journal of Arachnology because they copied the introduction of a 2011 paper verbatim.
The retraction was triggered by the first author, who “insisted on a full retraction in lieu of milder remedies,” according to the journal’s editor-in-chief.
The paper, “Alien spiders in Chile: evaluating Darwin’s naturalization hypothesis,” tested Darwin’s hypothesis that introduced species that are phylogenetically distant from native animals are more likely to thrive. It was published in April. Authors Andrés Taucare-Ríos and Ramiro O. Bustamante are both based at the University of Chile in Santiago.
The notice reads:
A natural disaster is to blame for a retraction about lethal brain tumors. At least, that’s where the authors say the problem started: with a 2010 earthquake that caused a loss of “substantial data.”
The paper, “Superoxide-dependent uptake of vitamin C in human glioma cells,” looks at how the cells of lethal brain tumors interact with the vitamin commonly used to reduce side effects of therapies.
Post earthquake, someone digitally filled in a western blot analysis of proteins from a cell line and rat brains, as a “temporary solution.” And then the temporary solution made its way into the Journal of Neurochemistry.
Here’s the retraction note from the journal, including an image of the sneaky western blot:
The Journal of Multivariate Analysis has retracted a paper it was never meant to publish — a problem, it seems, of multivariate analyses.
The article, titled “Regression estimation with locally stationary long-memory errors,” came from a pair of statisticians in Chile, Wildredo Palma and Guillermo Ferreira.
