Washington University runs a project Folding@home that uses computer time and capacity volunteered by users all around the world. In order to join the project, owner of a personal computer needs to install the software, which then runs in the background using spare GPU power for the calculations.
Foldit is a crowdsourcing game that enables individuals to participate in scientific research. In this particular case the project aims at determining structure of the 2019 coronavirus and finding a protein that binds to the coronavirus spike protein, thus blocking interaction with human cells. The project has multiple stages, and in each stage the players are presented with particular puzzles and attempt to resolve them.
