Thanks to @mireniraorb.bsky.social for the invaluable training in archaeological sampling and aDNA processing. This work would have not possible without you ❤️

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! 👩‍🔬

Local agricultural transition, crisis and migration in the Southern Andes - Nature In the Uspallata Valley, agriculture was adopted by local populations, as evidenced by genetic continuity from earlier hunter-gatherers to farmers; maize-dependent groups from the same regional p...

How did farming reach the Southern Andes? Through migration or cultural transmission? Our new paper in @nature.com combines ancient DNA, isotopes, archaeology & paleoclimate to reconstruct 2,000+ years of history in Uspallata, Mendoza.

I defend my PhD ( :O ) next week, and if you are interested in more of what I got up to over the past few years, you can check out an @nrc.nl here: www.nrc.nl/nieuws/2025/...

Having children plays a complicated role in the rate we age The effort of reproducing may divert energy away from repairing DNA or fighting illness, which could drive ageing, but a new study suggests that is only the case when environmental conditions are toug...

Antiviral reverse transcriptases reveal the evolutionary origin of telomerase Defense-associated reverse transcriptases (DRTs) employ diverse and distinctive mechanisms of cDNA synthesis to protect bacteria against viral infection. However, much of DRT family diversity remains ...

1/10 Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from?

Today, we report the discovery of telomerase homologs in a family of antiviral RTs, revealing an unexpected evolutionary origin in bacteria.
