This study uses genomic data from ancient and present-day individuals to trace the 4,000-year demographic history of Bantu speakers in the Congo rainforest, revealing early dispersals and a population crisis.

The paper generates a single-cell transcriptional atlas of Indigenous South American populations and shows genetic ancestry influences immune gene expression, particularly after stimulation.

The paper analyzes mumps virus circulation in the US using genomic data to show multiple co-circulating lineages and transmission patterns, but finds no evidence of vaccine escape variants.

This study sequenced 110 Zika virus genomes from 10 countries, revealing rapid expansion in Brazil, multiple introductions into other regions, and undetected circulation before confirmed cases.
