Published by the American Association for the Advancement of Science (AAAS), Science serves its readers as a forum for the presentation
and discussion of important issues related to the advancement of science, including the presentation of minority or conflicting points of view,
rather than by publishing only material on which a consensus has been
reached. Accordingly, all articles published in Science—including
editorials, news and comment, and book reviews—are signed and reflect
the individual views of the authors and not official points of view adopted by
AAAS or the institutions with which the authors are affiliated.
AAAS was founded in 1848 and incorporated in 1874. Its mission is to
advance science, engineering, and innovation throughout the world
for the benefit of all people. The goals of the association are to: enhance
communication among scientists, engineers, and the public; promote and
defend the integrity of science and its use; strengthen support for the
science and technology enterprise; provide a voice for science on societal
issues; promote the responsible use of science in public policy; strengthen
and diversify the science and technology workforce; foster education in
science and technology for everyone; increase public engagement with
science and technology; and advance international cooperation in science.
