Today, our paper on kinship and social organisation at the Early Bronze Age burial site of Leubingen was published! Lots of thanks to @haak_wolfgang @BRohrlach @AinashC Mario Küßner, Jan Nováček, Corina Knipper and Johannes Krause for making this possible!

We are excited to release READv2, a new version of the popular tool for detecting biol relatedness in aDNA data. @masterolojist made it faster and more precise than v1 while adding features for telling apart sibs and parent-offspring + 3rd degree

#MetagenomicsMonday 🧬
A large-scale #environmentalDNA metagenomic study of ancient plant and mammal communities! Researchers analyzed 535 permafrost and lake sediment samples from across the Arctic spanning the past 50,000 years. 🦣🫎🌿🌲 #sedaDNA

[Centre for Palaeogenetics @CpgSthlm]

Scientists from #CpgSthlm & @FriedlanderLab have for the first time recovered RNA from an extinct species! From ∼130 yr old dry tissue!

A game-changer for studies on gene expression in extinct species & RNA virus evolution (SARS, ebola, influensa, etc)?

Science’s carbon footprint - lab research produced an estimated 5.5 million tonnes globally in 2015, accounting for nearly 2% of total plastic waste. Now a @wellcometrust report looks at how health research can cut emissions https://t.co/2nXdwq4PRq

Extensive family trees provide insight into the social organization of a #Neolithic community. New study in @Nature by Maïté Rivollat, @haak_wolfgang & an intl. research team. @MPI_EVA_Leipzig @univbordeaux @PACEA_Bordeaux See: https://t.co/mRD6y5sb1X & https://t.co/ICi0jWBYrf

This example has four fletches, which were cut to shape and fastened to the arrow shaft using tar and thread. Hard to believe that the arrow is c. 1500 years old, but it is🙂

2-million-year-old microbial and viral communities disentangled using ancient environmental DNA. This was far from straightforward. Why? Take a read of our new preprint out today. Fantastic work by Antonio Fernandez-Guerra and team. @SedimentaryDNA ⁦🧵

Huge new paper on #Neanderthal birch tar just dropped!
New images & scans of the two Königsaue pieces, plus lots of v. exciting results, with the headline being:
- chemical analyses = *both* made using trickier oxygen-restricted, underground methods

In this preprint, I survey data archiving in ancient genomics—I find widespread shortcomings, which hinder reproducibility and data reuse. I argue that we need to step up our collective archiving game in #aDNA genomics, with six practical recommendations:
