I believe this is the original study: http://oagb.ru/lib.php?txt_id=12292 http://oagb.ru/lib.php?txt_id=12292 Alas, I cannot read it. Nevertheless, the way the story is told in the article, it is clear that this was not blinded. It is possible that the article was both clear and incorrect, I admit. (Also, I don't know what you mean by double-blinded in an animal study.) From the scientist interviewed in the article, it is difficult to tell if the animals were even randomized, though I assume they were. The last paragraph gives away the political nature of this experiment: "They suggest implementing the project, 'Safety Gene Technology' at the innovation centre, 'Skolkovo' which is being set up near Moscow." Update: the Russian livejournal author's page is Google-translatable, and she states that this study was not even single-blinded. And she points out that this could all be an inbreeding effect, since not enough information is given in the study to rule that out.
