New Scientist is a weekly international science magazine and website covering recent developments in science and technology for a general English-speaking audience. Founded in 1956, it is published by Reed Business Information Ltd, a subsidiary of Reed Elsevier. New Scientist has maintained a website since 1996, publishing daily news. As well as covering current events and news from the scientific community, the magazine often features speculative articles, ranging from the technical to the philosophical.

It is not a peer-reviewed scientific journal, but it is widely read by both nonscientists and scientists as a way of keeping track of developments outside their own fields of study or areas of interest.Many science articles in the general press are based on its contents,[citation needed] and it is a popular method for artists who are interested in art-science links to get information about scientific innovations, material about how the brain works, and perception.The magazine also regularly includes features, news and commentary on environmental issues, such as climate change.

Based in London, New Scientist has U.S. and Australian editions as well as a British edition.
