Bluesky is the new science Twitter, new study by @whysharksmatter.bsky.social and Julia Wester concludes!

"Results show that for every reported professional benefit that scientists once gained from Twitter, scientists can now gain that benefit more effectively on Bluesky than on Twitter."

🌾 Agriculture didn’t always spread with mobility of people.
New ancient DNA research shows that in western Anatolia, while communities stayed put, farming and village life spread through the movement of ideas and practices.

Révolution néolithique: Quand les idées voyagent plus loin que les individus Le passage à l'agriculture et à un mode de vie sédentaire est l'un des grands tournants de l'histoire de l'humanité. Pourtant, la manière dont ce mode de vie néolithique s'est propagé du Croissant fer...

🧬In Neolithic Çatalhöyük, family was built on social relations rather than blood ties.
Genetic analysis shows that over time, co-residents were no longer genetic relatives. Female subadults were buried with 5x more grave goods.
🔍A surprising story of Neolithic social life.

I didn’t know much about the Neolithic, neither had I ever heard the saying « pots don’t equal people ».

Well that changed, thanks to a real fun interview with @dilekopter.bsky.social and her colleagues behind this study (text also available in English, see comments) 👇

Our research confirms the archaeological adage "pots don't equal people." and showed ideas traveled further than people in the ancient Aegean.

"Background mobility", the low but steady movement of individuals sharing ideas and materials, can explain how Neolithic practices spread without mass migration in early Neolithic of Western Anatolia.

In West Anatolia, we found thousands of years of genetic continuity despite rapid cultural changes. People adopted farming through idea exchange, not population replacement.

Key findings: Our results showed that the Neolithic transition wasn't uniform: some regions saw cultural adoption, others experienced population movement, and some combined both.

Integrating paleogenomics and material culture data we found a complex mosaic of cultural change dynamics. This new methodology integrating genomics and archaeology reveals the diverse ways people interacted and changed during this period.

Out-of-Anatolia: Cultural and genetic interactions during the Neolithic expansion in the Aegean West Anatolia has been a crucial yet elusive element in the Neolithic expansion from the Fertile Crescent to Europe. In this work, we describe the changing genetic and cultural landscapes of early Hol...

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

Pre-processing of paleogenomes: mitigating reference bias and postmortem damage in ancient genome data - Genome Biology We investigate alternative strategies against reference bias and postmortem damage in low coverage paleogenomes. Compared to alignment to the linear reference genome, we show that masking known polymo...

Check out our new paper!

We studied reference bias in ancient genomes and proposed bamRefine, a new algorithm for PMD-correction.

We showed that graph alignment + bamRefine is the most practical solution to mitigate bias, and we urge the community to publish raw data!
