Three-dimensional genome architecture persists in a 52,000-year-old woolly mammoth skin sample

This paper reports the 3D genome architecture of a 52,000-year-old woolly mammoth using a novel method, revealing conserved epigenetic features across elephantids.

Demographic history and genetic structure in pre-Hispanic Central Mexico

The paper analyzes pre-Hispanic genetic data from Mexico to show population continuity despite climate change and identifies an ancient unsampled ghost population's contribution.

Ancient viral genomes reveal introduction of HBV and B19V into Mexico during the transatlantic slave trade.

This study reconstructs ancient viral genomes from Colonial-era remains in Mexico, linking their origin to Africa via the transatlantic slave trade.

Plasmodium vivax Malaria viewed through the lens of an eradicated European strain

The paper generates a genome from a historical European Plasmodium vivax strain, revealing its evolutionary relationship to American strains and the presence of drug resistance variants predating their use.

The genetic origins of Saint Helena’s liberated Africans

The paper uses ancient DNA analysis of 20 individuals from St Helena to determine the genetic origins of liberated Africans, finding they came from West Central Africa and were culturally diverse.
