Some positive AIDS news, for a change

>  It took Adam Arkin and David Schaffer just $200,000 and a grad student to develop a potential treatment for AIDS. And that scares them.

They genetically engineered a virus, whose mission in life is to kill HIV. It’s built from the shell of HIV, gutted and replaced with stuff that inhibits HIV’s reproductive abilities. It travels along with HIV, from person to person, in much the same way. This method could have some fairly serious drawbacks though – the new virus could mutate with the old one, to create an all-new potentially more dangerous strain.

Anyway, Wired News has the rest of the story.
