View a complete list of all research institutions, their research outputs, collaborations and more. Generate a table of institutions ordered by research outputs, by region or country/territory of interest, sector, subject area or journal group.
The Nature Research Intelligence Topics are created from networks of articles that cite each other, or articles that are very similar to each other, and we have over 30,000 topics at the most granular level, grouped into a 4-level hierarchy.

View trending research topics in the current window of the Nature Index.
Each topic page contains an auto-generated summary, leading institutions, leading countries/territories, a 5-year trend and top collaborators.
Institution profiles display leading research topics based on the institution's Share in the topic.

Discover the top-performing institutions and countries/territories in scientific research with the Nature Index Research Leaders.
Nature Index 2025 Science Cities
As coastal cities deal with the twin challenges of subsidence and rising sea levels, collaborations between researchers on the coast and those inland will be essential to finding solutions. This supplement highlights the insights that communities affected by climate change are sharing with researchers and policymakers, and explores changes in global climate data-monitoring.

Institution collaboration
Nature Index collaborations highlight the most fruitful institutional collaborations that lead to high quality research around the world. Naturally, proximate institutions collaborate the most, which hides the many benefits from collaboration further afield. To address this, the overallleading international collaborators are shown as well as the leading collaborations involving countries/territories outside the top 50 (broadening collaborators).

Country/territory collaboration
Country/territory collaboration looks at the leading collaborators around the world, as well as within and between between regions and equatorial hemispheres. To show trends in collaboration between any two countries/territories over the past 10 years we've introduced historical country/territory collaboration.
