We have added research topics to the Nature Index.
Nature Research Intelligence Topics are generated from networks of articles that either cite each other or are highly similar, resulting in over 30,000 unique topics. Organized into a 4-level hierarchy, the Nature Index presents topics from the 2nd level in natural and health sciences, that have enough articles to provide actionable insights.

Each topic page contains an auto-generated summary, tables of leading institutions and countries/territories, 5-year trend data and a list of the top collaborators. In addition on institution-specific pages, the new “Leading research topics” table highlights an institution’s areas of strength.
