A leading virologist at a uni in the states told me, I am not aware of any further details, it was just a throwaway line in an email he sent to me when we were discussing the XMRV and his reaction to it. On rereading my post I know it made me sound smug, I didn't mean it to come across that way, sorry - I just wanted to let you guys know the news without exposing the professor who I don't think would appreciate being on the record. Peace out.
