Global warming, renewable energy, infectious diseases, science education. Scientific American, founded in 1845, is the foremost publication for individuals who want to understand the science and technology that is shaping our world. John Rennie is only the seventh editor in chief in the 160-year history of SCIENTIFIC AMERICAN magazine. In 2000 the Council of Scientific Society Presidents bestowed on Mr. Rennie its Sagan Award for Public Understanding of Science, which is given annually 'to honor those who have become concurrently accomplished as researchers and-or educators, and as widely recognized magnifiers of the public's understanding of science'.
