:::But by the sound of it, the Swiss group's study is currently a self-published source which WP policy states "are largely not acceptable as sources" and which contravenes the rule of verifiability that you yourself quote as requiring sources to have "already been published by a reliable source" (my emphasis). Until such point as the study has been published by a third party (and ideally, although not necessarily passed peer-review) it is not reliable. Otherwise anybody could make up an experiment, fabricate the results, post it on their personal website and use it on WP. You're right that self-published sources may be used as sources of information about themselves, but only if the material "does not involve claims about third parties" and that "there is no reasonable doubt as to its authenticity" and "the article is not based primarily on such sources." Until we see the source we can't answer those three issues. 
 Can you post a link to it here so I can look at it? What language is it in?
