The biggest challenge during my PhD within sedimentary ancient DNA was to figure out how to bioinformatically process several hundreds of sequenced samples. This workflow is optimised for identification of eukaryotes from metagenomic shotgun data. Let me introduce the preprint of metaJAM! 1/6

Very excited to share our study of an ancient environmental genome extracted from lake sediment! It originates from a brown bear that lived around 9,600 years ago close to the last ice-sheet remains in northern Sweden, and has an unexpected mitochondrial haplogroup. 1/7 www.pnas.org/doi/10.1073/...

Excited to share our work on #AncientRNA from alcohol-preserved lungs, recovering the oldest human RNA virus genome (an 18th-century rhinovirus). Our study shows that viral RNA remnants persist in centuries-old tissue, opening new ways to study virus evolution and historical disease #Paleovirology🫁🦠
