If the link doesn't work then just go to google website, click on 'groups' and type in sci.med.vision. You will be redirected to google groups sci.med.vision.
The newsgroup sci.med.vision itself was yes not made by google. It was made by Grant Sayer. But in fact there is a sci.med.vison google group; I mean a sci.med.vision provided by Google. If you visit the link what I posted then you will see it. I think Dan You are just being silly and too fussy about google groups and newsgroups distinction.
Also Dan I don't think shistola is a actual word what you will find in the dictionary, but it is maybe an expression?
