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
