I don’t think there’s ever been a clearer example of the British media bullying someone, who was so clearly vulnerable, to death so shamelessly in my lifetime for engagement and clicks
And now we’ll have to watch the people that did it claim they’re shocked, and horrified

We had two great conferences last week, Radiocarbon and Diet and CLARa3.
Thank you so much for your participation and enthusiasm.
I hope we keep working together with the Radiocarbon community. And who knows…maybe in the future Chile will have a Radiocarbon facility (AMS included).

Delighted to have been awarded an ERC Advanced Grant for 'Stocking the Past' which will investigate the balance between arable farming and stockkeeping in Neolithic and Bronze Age Britain and Ireland using a range of isotopic and genomic approaches with a great team. Should be fun!

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
Our new paper builds a set of models to recover real-time seasonality data from serial enamel isotope profiles. It's currently operationalized for Equus, so please use the models on your horse and zebra serial isotope data! The paper is open access and available here: doi.org/10.1016/j.ch...

How did farming reach Uspallata?
Through migration of farmers—or through cultural transmission with local hunter-gatherers?
We address this through an integrative study of human remains spanning the last 2000 years, combining archaeology, isotopes and genomes.

We find strong genetic continuity through time, suggesting that agriculture spread without major population movement. Instead, local communities adopted farming practices while maintaining deep regional ancestry.

But we also find changes…
Isotopes reveal shifts in farming intensity, including a marked intensification of maize farming between ~800 and 600 years ago. And then we found something unexpected…

Strontium isotopes show that many of these individuals did not live in Uspallata and that the valley saw increased immigration. These were families with a matrilineal organization that migrated in succesive generations.

Why did they leave their homes?
We suggest it was a response to a long and multicausal crisis. Low populaiton size, climatic instability and the transmission of infectious diseases-tuberculosis- triggered migration along social networks. This was a resilient response.
