Speaking for Evidence

In times of uncertainty and concern about the future, AAAS and the Science family of journals communicate high-quality research and advocate for science with diverse scientific and public audiences.

The AAAS mission focuses our work on advancing science, engineering and innovation throughout the world for the benefit of all people. AAAS lives this mission by leading influential programs in science communication, education, policy, public engagement and international relations, and by partnering with our many affiliates, members and supporters.

In the past year, we shared information on breakthrough research advances with the scientific community, policymakers, reporters and the public; strongly advocated for the conditions that the research enterprise needs in order to thrive; provided valuable training and resources for students, scientists and engineers; and promoted research collaboration across disciplines and borders.

We are grateful to AAAS members and donors for their service and support on behalf of our organization.
