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.

That's because the therapy itself is a virus. The Lawrence Berkeley National Laboratory assistant professors created a virus altered to latch onto HIV and mute its ability to become AIDS. They've tested the theory in a computer model and in cells in a dish. The results have been promising, and if they continue in that vein, the researchers could begin animal testing by the end of this year.
