Article Synopsis
- The study investigates ancient microbiomes in archaeological dental calculus from 102 individuals across 10 Pacific islands and one island in Southeast Asia over ~3000 years, revealing insights into human migration patterns.
- DNA from oral microbiomes in dental calculus is better preserved than human DNA from bones, allowing for a clearer analysis of historical microbial communities.
- The oral microbial communities from the Pacific and Island Southeast Asia are distinct from those in Europe, Africa, and Asia, indicating that geographic factors influence the composition of these ancient microbiomes.
Background: Gout, the most common inflammatory arthritis disease, and hyperuricaemia onset are influenced by environmental and genetic factors. We sought to investigate these factors in an Indigenous community in Guam.
Methods: In this cross-sectional study, the University of Guam led the qualitative inquiry with the native community, training (pre-screening of participants, data collection methods, and biospecimen handling), study implementation (outreach and recruitment, data collection, and DNA extraction and quantification), and qualitative and epidemiologic data analyses.
The ethics of the scientific study of Ancestors has long been debated by archaeologists, bioanthropologists, and, more recently, ancient DNA (aDNA) researchers. This article responds to the article "Ethics of DNA research on human remains: five globally applicable guidelines" published in 2021 in by a large group of aDNA researchers and collaborators. We argue that these guidelines do not sufficiently consider the interests of community stakeholders, including descendant communities and communities with potential, but yet unestablished, ties to Ancestors.

Although the genetic diversity from this region is therefore crucial to decipher past population movements in South America, its characterization has been overlooked so far. We report 92 modern and 22 ancient mitogenomes spanning a temporal range of 5000 years, which were compared with a large set of previously reported data.

- The marbled polecat is a largely unexplored species in the Mustelidae family, particularly in terms of its phylogeny and genetic diversity.
- A study was conducted to sequence the mitochondrial genome of the marbled polecat and to understand its relationship within Mustelidae.
- The resulting mitochondrial genome is 15,982 base pairs long, featuring 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region.
