The paper identifies a plasmid, pTP33, unique to Second Pandemic Yersinia pestis strains, which may have increased transmission and mortality during that pandemic.

This study identifies the oldest known plague strains in Lake Baikal hunter-gatherers 5500 years ago, showing early outbreaks were lethal and challenged the idea that agriculture was necessary for plague epidemics.

This study uses environmental DNA from Lake Tjornin to challenge the narrative of Norse-induced environmental collapse in Reykjavik, showing dynamic human-environment interactions shaped by both cultural practices and external stressors.

The paper introduces efficient algorithms for fine-scale local ancestry inference using haplotypes, revealing recent selection on immune-related genomic regions in the UK Biobank.
