Statistical Rethinking 2026 is done: 20 new lectures emphasizing logical and critical statistical workflow, from basics of probability theory to causal inference to reliable computation to sensitivity. It's all free, made just for you. Lecture list and links: github.com/rmcelreath/s...

Just saw a great talk by @alnorwood.bsky.social about why you should use her models for your (obviously copious) zebra and other equid d18O data! Also why you should care about enamel histology (and she's done the worrying about it for you)! And to look out for upcoming bovid models #SAA2026SFO

A @nature.com study @ramiro-arqueo.bsky.social coauthored with Huarpe community leaders shows inhabitants of Argentina's Uspallata Valley welcomed migrants even during a crisis, and that people in the region are related to those buried there 2000 years ago. www.nationalgeographic.com/history/arti...

Wonderful article by @timvernimmen.bsky.social in Nat Geo on our recent @nature.com paper on the history of farming societies in the Andes

We are looking forward to welcoming #VanesaVillalbaMouco to #HEASVienna for a #HEASSeminar in #AncientGenomics online and in-person in the #UBB at @univie.ac.at More information and registration on our website 👇🔗

Our new paper led by Gwendoline Maurer is out! Seasonality and mobility at the Kura-Araxes site of Maxta I #stableisotopes #zooarchaeology journals.plos.org/plosone/arti...

We are pleased to share our new paper on the Iberian Aurignacian. We employed a quantitative approach to explore techno-typological variability and test its spatio-temporal dimension. @palomadelalasca.bsky.social Paper: doi.org/10.1371/jour...

Hoy es el día del Investigador y de la Investigadora Científica y si bien la situación es paupérrima celebro a todxs aquellxs que dedican sus días y sus vidas a la generación y aplicación del conocimiento en pos de la realización personal y del enriquecimiento de la sociedad y de la Nación 🇦🇷

Our recent paper in @nature How farming emerged in the Southern Andes. What were its consequences? #archaeology #dna #crisis #resilience

1/6 Just out in @Nature ! 🌽 The history of farming in the southern Andes. In a collaboration between archaeologists, geneticists and Huarpe Indigenous communities, we investigate its origins and consequences in the Uspallata Valley. Read: www.nature.com/articles/s41...

Avanza el conocimiento y ahora comprendemos mucho más sobre la incorporación de la agricultura del maíz en el sur andino 🌽 Excelente trabajo de @ramiro-arqueo.bsky.social y colegas aportando desde múltiples especialidades. 🧵con el artículo + un hermoso video

Congratulations to my former lab at @pasteuredu.bsky.social @nrascovan.bsky.social lead authors @ramiro-arqueo.bsky.social and #pierreLuisi and last but not least thanks @bitesizedna.bsky.social for hosting me at Copenhagen Uni for hours of drilling, extractions, and preps! 👩‍🔬

Archaeologists, geneticists and Indigenous communities together. How did agriculture spread in the Andes? Migration? Cultural exchange? How did farming affect human lives? Tomorrow we share new archaeological and ancient DNA evidence from the Southern Andes Stay tuned! #archaeology #dna @nature.com

🧬 Two pathogens, one disease. Leprosy cannot be understood as a single-pathogen disease. Understanding this duality is critical for modern case detection, surveillance, and long-term control strategies. A commentary with @nrascovan.bsky.social and @avanzich.bsky.social #Leprosy #OneHealth #aDNA

Sharing the commentary we wrote with @marialopopolo.bsky.social and @avanzich.bsky.social 👉 onlinelibrary.wiley.com/doi/10.1002/... in which we discuss the biomedical implications on Leprosy of our recent article on M. lepromatosis in the Americas: www.science.org/doi/10.1126/... @pasteur.fr

Did leprosy exist in the Americas before European invasion?

Ancient DNA studies usually link changes in lifestyle and language in the past to population movements. But not always! A new study in @nature.com reveals a South American ancestry that stayed steady for 8,500 years, despite major cultural and linguistic shifts. @science.org 🏺 🧬

Just out! we challenge the long-standing tradition of defining Upper Paleolithic cultures primarily through stone tool artefacts. Instead, we turn to personal ornaments to explore cultural identities during the past shorturl.at/8mxKe @univbordeaux.bsky.social @cnrsecologie.bsky.social

I'm super proud to share this piece of work, led by @nrascovan.bsky.social, @avanzich.bsky.social and @marialopopolo.bsky.social. See details in Maria's post here:

Big news in #GlobalHealthHistory today. A species of bacterium that causes leprosy, discovered in 2008 in modern patients, has been proven to have been present in the Americas well before European arrival. More details in 🧵 below: www.science.org/content/arti... #GlobalMiddleAges #histmed #aDNA 🧪

Wonderful research by @marialopopolo.bsky.social @nrascovan.bsky.social and a fantastic team. Congrats!!!

A new Science study shows that the mycobacterium M. lepromatosis infected humans in the Americas before European contact. The findings reshape current views of leprosy in the Americas and provide insights into the long-term interactions between humans and infectious diseases. scim.ag/3HuEjGB

Between 1637 and 1697, people who died at Milan's biggest hospital were dropped into underground vaults. Now their remains (including nearly 3 million bones & preserved brains) are helping archaeologists reconstruct the lives, diet and drug habits of people historians often overlook. @science.org

Happy #WorldDownSyndromeDay. It falls on 3/21, because people with Down syndrome have three copies of the twenty-first chromosome. This is the best Down syndrome PSA ever made and I want you to watch and share it. #WDSD2025

Really important, and useful thread. One thing it shows - scientific community needs to organise

Ypres was one of 13th-century Europe’s economic powerhouses. Bart Lambert’s MOTC project drew on isotopic analyses of human skeletons to reconstruct mobility patterns of its inhabitants. Their new paper discusses evidence of regional, female and children’s mobility. link.springer.com/article/10.1...
