Science is the academic journal of the American Association for the Advancement of Science and is one of the world's top scientific journals. The peer-reviewed journal, first published in 1880, is circulated weekly and has a print subscriber base of around 130,000. Because institutional subscriptions and online access serve a larger audience, its estimated readership is one million people. 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. Unlike most scientific journals, which focus on a specific field, Science and its rival Nature cover the full range of scientific disciplines. Science's impact factor for 2010 was 31.364 (as measured by the Institute for Scientific Information).
By using new data from NASA's Chandra X-ray Observatory and Neil Gehrels Swift Observatory as well as ESA's XMM-Newton, a team of researchers has made important headway in understanding how—and when—a supermassive black ...

A trio of chemists at the University of Copenhagen has developed an AI application that can be used to figure out the phase of x-rays that crystals have diffracted as part of efforts to predict the structure of small molecules.
Bacterial small molecule metabolites, such as adenosine-diphosphate-d-glycero-β-d-manno-heptose (ADP-heptose) and their derivatives, act as effective innate immune agonists in mammals.
