Join the Force for Science

The American Association for the Advancement of Science has been the Force For Science since 1848.  We are still standing up for and defending science today and will continue to do so for years to come.

We all need science — to advance medical research, develop new methods of clean energy and uncover new technologies. Now is the time to become part of the global force dedicated to advancing science.
