Compute for Science

BOINC lets you help cutting-edge science research using your computer (Windows, Mac, Linux) or Android device. BOINC downloads scientific computing jobs to your computer and runs them invisibly in the background. It's easy and safe.

About 30 science projects use BOINC; examples include , , and IBM World Community Grid. These projects investigate diseases, study global warming, discover pulsars, and do many other types of scientific research.

You can participate in either of two ways:

Choose science areas

To contribute to science areas (biomedicine, physics, astronomy, and so on) use Science United. Your computer will do work for current and future projects in those areas.
