Interesting video and the first time I've really looked at/listened to anything related to the virus minus high school students going nuts over it in class and watching on their phones the spread.
Perhaps, most interesting to me is why the latency factor? Why, or to what end were they engineering it in the first place? In my mind, based on the copy/paste there is absolutely no way that it wasn't engineered (for any who question that aspect).
The video makes this a bit more confusing if you ask me. It's very easy to splice a gene, take a section and copy and paste in, I for one created a glowing e-coli in a basic community college genetics class years ago, so I am confused by his somewhat positive belief that part was engineered and that the possibility of this "folding" was just a chance mistake? Yes, perhaps, but likely not with as much time has passed since beginning to play with these things. Sounds to me like they've been working on this particular project for some time and maybe their Frankenstein did work better than they thought and got out of hand, but still they were messing with the HIV antigens which we know attack the immune system and lower white blood cell count for a reason. As I'm typing, I'm thinking this latency factor may have just been a carry-over related to the way the HIV virus operates and not necessarily what was wanted in the creation of a Super virus?
And, as far as coming from bat SARS, etc. for the general masses, this matters next to nil, but how to fight it does, so I suppose good to narrow in on how it effects that organism?
