The "8% of your genome" comes from the first paragraph of the News and Views article which reviews the actual article by Horie et al, and is referring to ALL viral remnants in the human genome, not just this new Bornavirus one. From a quick scan of the paper, it looks like they didn't estimate what fraction of the human genome comes from their Bornavirus, but they only describe 4 actual elements - so that's a vanishingly small part of the human genome. The vast majority of viral elements in the genome come from retroviruses and other retrotransposons, and that's been known for a long time.
Yeah, I thought the exact same thing. A Firefox plugin that will detect when you download a PDF from some journal, and automagically upload the PDF to some open repository. That would be of immense use to scientists who don't have access to all the many expensive journals out there. Unfortunately, since almost all journals force authors of the papers to relinquish copyright to the journal, a open-access database of papers would copyright-infringing as hell. You'd have to host it some non-copyright-friendly country........
A great idea tho - I'd use it in a second! I download probably 50 papers a month from various paywall journals!
The only problem with being a man of leisure is that you can never stop and take a rest.
