HIV Rides Seminal Protein Rafts To Uninfected Free Worlds

Men are so gross. New research shows male semen contains a protein fragment that boosts HIV transmission by 100,000 times. From the Gate:

The fragments dramatically boost HIV infection by clustering into microscopic rafts that ferry crowds of virus particles to cell surfaces, like landing craft disgorging invaders on a beach. ... When researchers try to infect human cells under a microscope with HIV, it takes between 1,000 and 100,000 particles of the virus to cause a successful infection. That's weak, as viral infectivity goes. But when the proteins found by Kirchhoff are added to the mix, it is possible to trigger a successful infection with as few as three particles of virus.

Scientists are working on a way to neutralize said protein, meanwhile two stopgap measures are being enforced: more lesbianism and facials. —David Downs
