Brazilian science, read through PubMed

48,676 Brazilian researchers, profiled like single cells

We linked the journal articles listed in the Lattes CVs of Brazilian PhD holders to PubMed, counted the MeSH terms on each researcher's articles, and analysed the result with the toolkit built for single-cell RNA-seq. Each researcher is a cell. Each MeSH term is a gene.

Concept by Helder Nakaya · CSBL

DataLattes CVs (CNPq) from the BaseD collection, obtained by Prof. Jesus Mena-Chalco's lab. PubMed/MEDLINE records from the U.S. National Library of Medicine.

ConceptHelder Nakaya conceived the approach of representing researchers as single cells and MeSH terms as genes to map scientific activity.

From Lattes records to PubMed

Explore the publication records behind this atlas, before the MeSH-based single-cell analysis.

How the dataset was assembled. These descriptive analyses cover publication histories, PubMed coverage and title linkage. They do not use single-cell normalization, clusters or UMAP coordinates. The distribution includes all 453,549 researchers; the scatter plot starts with those who have at least 100 PubMed-linked records. The map elsewhere uses a separate cohort of 48,676 researchers with usable MeSH profiles.

01 · Publication histories

Who publishes in PubMed, and when did they start?

First publication in English versus PubMed-linked record count. Search a name to highlight a researcher, or select a point for details.

02 · PubMed coverage

How many researchers have PubMed-linked records?

All 453,549 researchers in the source summary, including those with zero linked records. This chart is independent of the scatter plot filters.

03 · Title linkage

Where do the article records go?

Follow all Lattes journal-article records through English-title detection and PubMed linkage. Hover over a flow for its count, or read the table below. Counts refer to CV records, so shared papers can appear under multiple researchers.

Counts are linked CV records, not deduplicated papers or measures of research quality. First English-publication year refers to the records available in this dataset, not necessarily the beginning of a researcher's career. Source: BaseD, August 2026 update. Read the methods and data credits →
