Sox2 explained it pretty well, I'll try to dumb it down even more. Certain enzymes recognize patterns on DNA, and chop them right at that location. HIV is a virus that inserts itself into your DNA (unlike most viruses, which just use your cells resources to reproduce). The scientists evolved an enzyme that recognizes the sites on either side of the HIV, chops them up, and splices them back together--effectively removing the HIV.
The reason it's "preliminary work" and not a magical cure is because the 'patterns' recognized by the enzymes (and the enzymes themselves) were morphed into "fake" sites. In actuality, it's much harder to create enzymes that recognize the actual patterns of the HIV. In addition, these enzymes might find patterns elsewhere in DNA and accidentally chop up your DNA in the wrong locations, removing important parts of your DNA.
Dozens of people have already replied with different technologies, and they all use one reference medium: wikipedia.
Why is wikipedia not on the list? I consider this the best invention of technology ever--a method that combines the power of the internet with the minds of people.

Not to mention the fact that they can probably design it to only block visible light--perhaps infrared or radio communication would work?
