Science, also widely referred to as Science Magazine, is the academic journal of the American Association for the Advancement of Science and is one of the world’s top scientific journals. The major focus of the journal is publishing important original scientific research and research reviews, but Science also publishes science-related news, opinions on science policy and other matters of interest to scientists and others who are concerned with the wide implications of science and technology. Specially interesting is the Science in the Classroom section, a collection of annotated research papers and accompanying teaching materials. Unlike most scientific journals, which focus on a specific field, Science and its rival Nature cover the full range of scientific disciplines.
