What the fuck does anything in that study have to do with OPs question about how viruses are created or spread?

So you can put cancerous neurons and virus samples in a petri dish together and the one will "infect" the other? Yeah and i can infect a cheeseburger into my stomach but that has precisely fuck all to do with where the cheeseburger came from.

Nice try says the guy who hasn't read the first post link. What is posted here still doesn't explain away the premise in the article. I've had too much to drink and I'm going to drop it here to avoid making an ass out of myself. Appreciate your effort regardless, have a good evening, friend.
