Nations expanding their research programmes impose sweeping penalties for malpractice
India, Peru and Vietnam are rolling out policies that limit opportunities for scientists who fall foul of research-integrity guidelines.
We are currently gathering feedback from the research community on potential new Nature Index data products and analytics capabilities. If you use Nature Index data for research performance assessment, strategic planning, benchmarking, reporting, or collaboration analysis, we encourage you to share your views through our short survey.

Nature Index 2026 Nanoscience and nanotechnology
From programmable RNA architectures to next-generation materials for energy and healthcare, researchers are harnessing the unusual properties of the nanoscale to tackle some of society's biggest challenges. This supplement explores the discoveries that are driving the field, the hurdles that remain and the institutions that are leading in nanoscience and nanotechnology research.
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.

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 level 2 topic page included in the Nature Index 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.
