Gamers Help Fight AIDS

Online players solve a tough problem that had scientists stumped for a decade.

For more than 10 years, health researchers have been stumped by an enzyme that helps retroviral infections like AIDS reproduce. Biologists studying the enzyme were unable to model its shape, a crucial first step in figuring out how to beat it.

Recently scientists turned the problem over to an unusual team of collaborators: video gamers. Using Foldit, a free online protein folding game developed at the University of Washington in 2008, those gamers competed to see who could produce the most accurate virtual model of the real-life enzyme.

In just three weeks, gamers accomplished what scientists had been unable to do for more than a decade—no special scientific under- standing required. The game offers players an intuitive 3D modeling interface that can be learned in just a few minutes. It then awards a score for each model; a higher score means a virtual virus that more closely fits the known requirements for the enzyme. 

For gamers, it's a milestone. "This is the first instance that we are aware of in which online gamers solved a longstanding scientific problem," according to an article published online by Nature Structural & Molecular Biology in September. But it won't be the last. The game goes on, and according to Foldit's blog, more scientific revelations are already on the way.
