Online gamers crack AIDS enzyme puzzle

Gamers solve molecular puzzle that baffled scientists” There is this website, Fold.it. People go there to play a video game about Protein Folding. Players can contribute to science by solving these puzzles. Wikipedia sums up the news nicely: “. . . online gamers used Foldit to decipher the crystal structure of M-PMV retroviral protease, which is linked to an AIDS-like virus. Players produced an accurate 3D model of the enzyme in just three weeks. The problem had thwarted scientists for a decade.”   This is significant: We haven’t hit the singularity yet, but the ...
