Researchers need the public's help in observing the behavior of tiny nematode worms. Citizen scientists visiting Wormwatchlab.org are shown a video of a worm wriggling around. The aim of the game is to watch and wait for the worm to lay eggs, and to hit the 'Z' key when they do. By watching these worms lay eggs, citizen scientists are helping to collect valuable data about genetics that will assist medical research.
