Results now show more than 55,000 players have played protein-folding Tetris, and beat the world's most powerful computers on problems that required radical moves, risks and long-term vision.

During this 2010 "Sort Benchmark" competition -- the "World Cup of data sorting" -- the computer scientists from the UC San Diego Jacobs School of Engineering also tied a world record for fastest data sorting rate.
