Nearly half of the world’s Nature Index chemistry research is now done in China
A breakdown of leading countries and institutions highlights China’s dominance in the field.
Your gateway to scientific excellence
Discover the world’s leading research institutions, explore collaborations, compare research performance, track top papers with Nature Index.
Institution search supports local language names. (Examples: Universidad Autónoma de Madrid, 筑波大学)
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.
Nature index is planning on expanding to cover the applied sciences by adding a selection of publications following a survey of the research community.
Discover the top-performing institutions and countries/territories in scientific research with the Nature Index Research Leaders.
Nature Index 2026 Chemistry
Chemistry research is undergoing a period of transformation, driven by new technologies and mounting environmental pressures. In this supplement, we explore the trends behind China’s extraordinary rise in chemistry output, and why efforts to curb the use of PFASs are accelerating worldwide. We also look at the innovations that could redefine how chemicals are designed, produced and recycled.
Nature Index 2026 Cancer
Cancer incidence is on the rise. Countries are meeting the challenge in different ways, such as through nationwide action plans and broadening early detection programmes. However, coordinating these efforts to make them accessible, targeted and effective is a balancing act. In this supplement, we explore the factors that are shaping these first lines of defence and the research efforts that are informing them.

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.
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 overall leading 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.
