New Scientist is a weekly non-peer-reviewed English-language international science magazine, founded in 1956. The magazine covers current developments, news, reviews and commentary on science and technology. It also prints speculative articles, ranging from the technical to the philosophical. Readers contribute observations on examples of pseudoscience to Feedback, and questions and answers on scientific and technical topics to Last Word; extracts from the latter have been compiled into several bestselling books, published by Profile.
