Two papers to which I contributed came out back to back in Antiquity recently, which discuss African ancestry in early medieval individuals from England. Even though the data has been available since 2023, we now dedicated more space to these two special samples, and highlight this unusual […]

There is a very nice documentary about the ancient Saxons on Arte and YouTube available here: https://www.youtube.com/watch?v=tzwMzEEnKEE It features our genetic study from 2022 (https://www.nature.com/articles/s41586-022-05247-2), with prominent interviews of lead authors Joscha Gretzinger and […]

#SMBE #SMBE2025 Just notice the preprint of Rare Allele Sharing (RAS) statistics was out on the same day of my talk in @official-smbe.bsky.social . Great thanks to my supervisor @stschiff.bsky.social and co-author Thiseas Christos Lamnidis!

Pls spread the word! We have a postdoc position available in the Rocha Lab @mpi-muenster.bsky.social. Join our team to study mechanisms underlying robust organ development using zebrafish embryos and human organoids. mpi-muenster.mpg.de/career

Happy to share our new study from my PhD on the spread of farming across Anatolia and into the Aegean and then into Europe. @compevohumang.bsky.social www.science.org/doi/10.1126/... 👇🏽

Postdoc position in my group in Tokyo! Please get in touch if you are interested. And happy to discuss projects - these would range from developing new methods to analysis of new genomes that we are now sequencing in the lab. Job Ad: www.riken.jp/en/careers/r... Lab page: speidellab.github.io

Hallo Oberbergischer Kreis! Am 27. Mai spreche ich in der #Demokratiekirche Oberberg: www.demokratiekirche-oberberg.de/veranstaltun...

Scientists used to think diseases that jump from animals to people really took off when people started domesticating cattle, sheep and goats 11,000 years ago. A new look at ancient bacterial DNA in @science.org by @poojaswali.bsky.social and colleagues suggests the pivotal moment came much later.

Really impressive and moving interview by @baym.lol about the Harvard cuts.

Woah. Two of my top trigger words in one paper. Gotta read!

Fascinating new study by Lara Cassidy and Colleagues on a South British Iron Age burial site with an extraordinary matrilocal relatedness pattern (www.nature.com/articles/s41... 1/6

Now this is how #aDNA *and* the #archaeological record are teaming up - The fascinating case of #IronAge Britain's #matrilocality: 🏺 www.science.org/content/arti... by @spoke32.bsky.social via Science Mag

More than 15 years ago I went to @auschwitzmemorial.bsky.social to understand the link between memory and preservation. I was lucky enough to speak with survivors of the camp, only one of whom is still alive. I think the piece I wrote for @smithsonianmag.bsky.social remains relevant today.

Problem solved!

Excellent book review on "The trouble with ancient DNA" by my colleague Kathrin Nägele at the MPI for Evolutionary Anthropology: www.science.org/doi/10.1126/... #adna #books #science

Nice article in National Geographics (in German) on our findings of dynastic relationships among Celtic elite burials, featuring Angela Mötsch from my group: www.nationalgeographic.de/geschichte-u...

#Vortrag am #LEIZA #Mainz Am Donnerstag 16.1. spricht Miguel Morillo Leòn (@uni-kiel.de) über "Bασιλ ̑ηας δωροφάγους. How mobility and exchange shaped Mediterranean Late #Prehistory and how to trace it through the Archaeological record" Aus der Reihe "Time Talks" von LEIZA und @unimainz.bsky.social.

"Ancient DNA reveals family ties" is named on of the top 10 Science Break-throughs in 2024 by Science (www.science.org/doi/10.1126/...). Our work on early Celtic princely burials and their discovered close kinship gets mentioned, too! #ancientDNA #science

Surprising the number of things that sort of work like bank runs

DOGE is literally just this, down to the ridiculous acronym, but with the two most unlikable douchebags in America instead of an awesome kid and even more awesome tiger.

Scientists, academics, researchers: We’re excited to share that @altmetric.com is now tracking mentions of your research on Bluesky! 🧪

This study introduces new methods to estimate hierarchical F–statistics for Pool–Seq data. These methods improve upon traditional F_ST statistics by considering the complex structures within populations. This helps provide a clearer understanding of genetic diversity and differences among groups.

So, who had "Boris Johnson sensationally solves whatever mystery Rapa Nui holds to just end up with the old (and false) ecocide narrative" on their 2024 bingo card? 🏺🤨

Aus der Serie alte Tweets, kurz nach Regierungsbildung 2021. Man darf ja auch mal stolz auf ne richtige, frühe #Prognose sein?😁Zumal Alfred Grosser immer witzelte, Politologen seien Wissenschaftler, die NACHHER erklärten, warum man VORHER hätte wissen können, wie es laufen wird.

For no particular reason here’s a nice new fine-scale study on (mostly) modern and some ancient (medieval) genomes from northwestern France. Includes an individual from Chaussé Saint-Pierre, Angers dating to 414–548 cal. AD who carried predominantly ancestry from North Africa. t.co/BttbzsNtyc
