What a fantastic conference dinner we had yesterday at the Golden Hall 🪙 of Stockholms City Hall! 🏫 Even the full-delegate (>380) conference group picture we thought we couldn't pull out, happened organically 📸🎉

Happy to not wear orange potentially ever again with the 5-1 thrashing still fresh in memory, but what a fun conference this was! Enjoyed meeting old friends, and making new ones. Still buzzing from all the fantastic science presented! #ICP2026
ICP2026 Stockholm@palaeogenomics.bsky.social · last mo.♥️ THANK YOU ♥️ We are overwhelmed by the positive comments and are incredibly happy that everyone enjoyed their time in Stockholm! #ICP2026 was only possible with the hard work of the organizing committee and a marvellous team of ECR volunteers 🟠 at @cpgsthlm.bsky.social
Isabelle Feinauer is currently defending their PhD thesis on the genomic consequences of postglacial recolonization of Scandinavian mammals with Morten Tange Olsen as the opponent. Good luck, Isa!
🧬 New paper in Cell! Analysis of 12 cave lion genomes shows that cave lions and modern lions may have diverged more than three times earlier than previously thought – as early as 1.7 million years ago! AND…they interbred when temperatures dropped! Paper: www.cell.com/cell/fulltex... 🧵 1/9

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

New paper alert 🚨 A study led by #CPGSthlm researchers found DNA from a bear in 9.6k year old lake sediments. This potentially rewrites the history of brown bears in Scandinavia! 🧬🐻🐾🏔️🧊 Check @officialernst.bsky.social thread 👉 bsky.app/profile/offi... OA article 👉 www.pnas.org/doi/10.1073/...

Ernst Johnson@officialernst.bsky.social · 4mo agoVery 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/...
Check out our study!
Proceedings of the National Academy of Sciences@pnas.org · 4mo agoBrown bear DNA recovered from 9,600 year-old lake sediment captures information about a single male bear living in what is now northern Sweden. Surprisingly, the bear had genetic signatures associated with southern Swedish bears . In PNAS: https://ow.ly/FcnG50YMPP8
It's wonderful to live in an era where you can extract ancient genomes from lake sediments and obtain this kind of information! Amazing what can be revealed with sedaDNA.

A single wandering male bear has provided crucial insights into the history of brown bears in Scandinavia after the last ice age. This is shown by DNA analysis of clay from a lake. New study from @cpgsthlm.bsky.social & @zoologysthlm.bsky.social published in @pnas.org www.su.se/english/news...
