I really need to see the report before I comment on what the scientists have done; but,... I have suspicions about some of the materials and processes used in the experiment which would really call into validity the usefullness of this data.
This looks awfully familiar to the Pall Corp. blood test in which they claimed they could remove prions from the blood. First, they added prions to the blood and then they removed them.
I doubt the "prion" in this new study is the full prion protein. It is probably only a portion of the prion - lacking the glyco-anchor. If this is the case, of course it would move around, as the anchor is not present to attach it to the cell surface. And, once again it is an inoculation procedure which skips alot of natural processes involved. I'll have to get my hands on it, and get some further comments from other TSE researchers.
Dr. Vitaly Vodyanoy, at Auburn, has a link that shows the "Borrelia burgdorferi" that causes "Lyme disease" boring into a living cell, using dark-field microscopy at: (see Video Demonstration)
I would hope that since the Rocky Mountain Labs study was partially funded by the NIH, that everyone can access this study for free.
