context_page_description: Nature's 10 is an annual listicle of ten "people who mattered" in science, produced by the scientific journal Nature. Nominees have made a significant impact in science either for good or for bad. Reporters and editorial staff at Nature judge nominees to have had "a significant impact on the world, or their position in the world may have had an important impact on science". Short biographical profiles describe the people behind some of the year's most important discoveries and events. Alongside the ten, five "ones to watch" for the following year are also listed.
