Retracted Seralini GMO-rat study republished

env sci europeA highly controversial — and retracted — 2012 study by Gilles Seralini and colleagues of the effects of genetically modified maize and the Roundup herbicide on rats has been republished.

Retraction Watch readers may recall that the editor of Food and Chemical Toxicology decided to retract the heavily criticized paper because it was “inconclusive.” The editor, A. Wallace Hayes, claimed that this was consistent with Committee on Publication Ethics (COPE) guidelines, although we and many others disagreed.

Here’s the original abstract of the Food and Chemical Toxicology paper, which has been cited 55 times, according to Thomson Scientific’s Web of Knowledge: Continue reading Retracted Seralini GMO-rat study republished

Update: Lab head shares “painful” process that led to Molecular Cell retraction

molecular cell 14Last month, we published a guest post by Jean Hazel Mendoza about the retraction of a Molecular Cell paper for sampling errors, flawed analysis, and and miscalculation.

Mendoza heard back from Jean-François Allemand, the head of one of the labs involved. Allemand tells Retraction Watch by email that when his group tried to repeat the experiment, they suspected of “missing” or “averaging” of data points in the retracted paper: Continue reading Update: Lab head shares “painful” process that led to Molecular Cell retraction

Paper claiming a way to “print any drug instantly” gets unprinted

ddtA recent paper proposing a way to “print any drug instantly” has been withdrawn by the author, following bewildered reactions from the blogosphere.

The paper made the rounds at various chemistry-focused blogs last month. Derek Lowe of In The Pipeline picked up on it too, calling the article

one of the oddest papers to appear in Drug Discovery Today, which is saying something.

Apparently, the author — or someone claiming to be the author, using the initials YC — wasn’t crazy about the criticism. He left this comment on In The Pipeline and elsewhere: Continue reading Paper claiming a way to “print any drug instantly” gets unprinted
