Twenty-three new Yersinia pestis genomes from Scandinavia, the Netherlands, Iceland and Armenia extend the Second Plague Pandemic phylogeny, with the first Icelandic plague genome and eastward-spreading pestis secunda strains.

The paper sequenced Norwegian farmhouse yeasts to study their genetic diversity and domestication history, finding they form an early diverging lineage with distinct phylogenetic and population genetic characteristics.

This study analyzes ancient DNA from three European sites to assess the genomic impact of the second plague pandemic, finding no strong positive selection but evidence of reduced long-range immigration post-pandemic.

This study combines histological and metagenomic analyses of archaeological human bones to investigate microbial communities involved in bone degradation, finding that preservation state correlates with microbiome composition and that Streptomyces is prevalent.

The paper critiques a study that claimed to identify ancient plant and fungal DNA in Puerto Rican coprolites, arguing that the results lack proper validation and cannot conclusively support the dietary claims.

This study evaluates the accuracy of genotype imputation for ancient genomes and finds it comparable to modern DNA, with some population-specific biases.

The paper sequences a 5,700-year-old human genome and oral microbiome from Stone Age chewing gum, revealing genetic and microbial insights.

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.

This study applies Y-chromosome capture-enrichment to ancient DNA libraries, showing increased recovery of Y-DNA sequences and enabling haplogroup assignment.

This study improves endogenous DNA recovery from ancient bones and teeth through optimized enzymatic pre-digestion, increasing endogenous DNA content by up to 14 times in teeth.
