For 15 years, scientists and their computers had tried to solve a biological puzzle seen as a key hurdle in the fight against AIDS.
On Sept. 18, the journal Nature Structural & Molecular Biology announced that two teams of computer gamers had solved it in three weeks.
Using a game called FoldIt, the teams uncovered the structure of a class of proteins scientists say is vital to the growth and reproduction of the virus linked to AIDS. The discovery could help scientists neutralize the protein.
FoldIt represents a unique approach toward engaging citizen scientists, and it is the latest innovation in a decade-long trend – researchers enlisting everyday people and their personal computers to take part in humanity's scientific enterprise.
Some scientists, like FoldIt's creators, seek to tap the competitive, problem-solving skills of gamers. Others are asking outsiders to make their computers part of data-crunching networks. And some amateurs are helping to classify everything from distant galaxies to features on the moon.
