HIV Transmission Captured On Video
Technology Review has promising news on the AIDS front: researchers have captured HIV T cell transmission on video. The upshot could be new avenues of treatment. "The resulting images and videos show that, once an infected cell adheres to a healthy cell, the HIV proteins... migrate within minutes to the contact site. At that point, large packets of virus are simultaneously released by the infected cell and internalized by the recipient cell. This efficient mode of transfer is a distinct pathway from the cell-free infection that has been the focus of most prior HIV studies, and reveals another mechanism by which the virus evades immune responses that can neutralize free virus particles within the body."
It's been caught on video many times before - and sold.
Scary stuff, really.

The blurb does kind of make it sound that way, the third sentence in the actual science article cites a 1993 paper: "In vitro, infection with cell-associated HIV can be thousands fold more efficient than infection with cell-free virus."
I disagree. This assumption of everyone being racist/homofobic/etc. until they "prove" that they aren't by belonging to the group in question is offensive to me as a nonracist, etc..
The joke was the same regardless of who said it because the end result for us readers is the same. If it is something that can make us laugh, it is good. If not, it isn't.
And for the record, I think it was a pretty sucky joke regardless of the poster's health. -1 is appropriate
No, if it killed instantly then people wouldn't need to be careful not to get it because it would be extremely rare (unless it had a very common transmission vector which it didn't kill).
