Study Linking GM Maize To Rat Tumors Is Retracted
ananyo writes "Bowing to scientists' near-universal scorn, the journal Food and Chemical Toxicology has fulfilled its threat to retract a controversial paper which claimed that a genetically modified (GM) maize causes serious disease in rats after the authors refused to withdraw it. The paper, from a research group led by Gilles-Eric Séralini, a molecular biologist at the University of Caen, France, and published in 2012, showed 'no evidence of fraud or intentional misrepresentation of the data,' said a statement from Elsevier, which publishes the journal. But the small number and type of animals used in the study means that 'no definitive conclusions can be reached.' The known high incidence of tumors in the Sprague-Dawley rat 'cannot be excluded as the cause of the higher mortality and incidence observed in the treated groups,' it added. Today's move came as no surprise. Earlier this month, the journal's editor-in-chief, Wallace Hayes, threatened retraction if Séralini refused to withdraw the paper, which is exactly what he announced at a press conference in Brussels this morning. Séralini and his team remained unrepentant, and allege that the retraction derives from the journal's editorial appointment of biologist Richard Goodman, who previously worked for biotechnology giant Monsanto for seven years."
Imo, withdrawing papers makes sense mainly if there is indeed, "evidence of fraud or intentional misrepresentation of the data". Faked data doesn't help advance science, and should be purged from the record.
But merely questionable conclusions are another story. Science is a back-and-forth process: someone publishes a study purporting to show X, and then someone else criticizes their conclusions, re-analyzes their data, attempts to replicate it, etc. Then they publish their own conclusions, purporting to show not-X. Withdrawing the original study in this case doesn't make sense to me, if it was not fraudulent: we don't typically retroactively go into old journals and blank out the articles that have subsequently turned out to be wrong. We just write new articles with better analysis.

Funny how Monsanto isn't required to definitively prove their crap is safe, but everyone else is required to definitely prove that it isn't.
So basically we've got an evidentiary double-standard where Monsanto et al get to say "perfectly safe until proven otherwise", and we don't get to say "prove it". And then we all get to be the test subjects in the long-term studies.
And, more importantly, having worked at Monsanto should automatically exclude you from being considered from holding an editorial position like this. You mostly have to assume these guys are going to be paid shills who have already made up their mind that it's safe, and he's basically just demonstrated that Food and Chemical Toxicology isn't interested in objective science.
Lost at C:>. Found at C.
Fortunately, in this case, it's ok to be annoyed by both sides: Elsevier and the guys who did the study. Both are bad.
"First they came for the slanderers and i said nothing."
They're not Monsanto fanboys - simply ignorance haters. Monsanto might be corrupt, but they're nowhere near as evil as hippie conspiracy theorists think.
Direct health effects of GMO foods are IMHO only the third most important potential concern with GMOs.
The first concern is that whatever you have engineered, it is self-reproducing and could potentially take over a niche in a whole ecosystem, displacing other species or naturually adapted varieties, and you in general could not stop this if it happened. So eco-systems then become fully the responsibility of human biology tweakers.
This seems generally unwise. The consequences of such ecosystem shifts is too complex to be predicted.
A second concern is that each genetic engineering modification needs to be fully assessed separately from all others, due to the complexity of the systems into which they are being inserted. Or at least, very narrow equivalence classes of modifications need each to be individually, and in combination, re-tested for long term effects, viability, viability and effects of likely mutations of the tweak etc, each time they are tweaked.
The cost of such repeated and long term safety testing is well beyond the capability of the companies producing the products, so we can be sure that such rigorous, long term, and repeated (when product is varied) testing is not being done.
Instead, smaller numbers of specific tests on a subset of engineered varieties are generalized in alleged applicability and conclusion, to save money.
So there is still a lot of know unknown and unknown unknown out there, and it is the kind of product that in general, self-reproduces and also expands in range.
Where are we going and why are we in a handbasket?
