🇵🇹Our paper on Portugal's genetic history is now published in @GenomeBiology. We present the largest collection of ancient Portuguese genomes, with deeper analyses than our pre-print, revealing migrations, admixture and remarkable continuity https://t.co/RO8vrL4FJw @TeixeiraJoaoC

🚨 Check out our new paper in Nature!

In our new study, we sequenced 128 high-coverage genomes from Indigenous peoples across Latin America and uncovered their unique genetic diversity and history. 👇🧵

New release of the AADR. In addition to improved curation / group IDs, and more samples (now >23,000), this release include a dataset pulled down on the Fournier et al "compatibility" SNP set which reduces 1240K, TWIST, and shotgun biases to maximize co-analyzability

So happy to see this work on the genetic history of the Central Southern Cone published in @Nature 🌎🧬 Huge congrats to @javier_maravall and everyone involved!

[Javier Maravall-López @javier_maravall]

Happy to see our study on the genetic history of the Central Southern Cone (CSC) of South America, the first piece of work from my PhD, out in @Nature! https://t.co/IhbcVLPdo0

🚨 New paper!
🧬 We explore ancestry shifts, kinship ties & Mediterranean links at Mas d’en Boixos (Catalonia), from the Neolithic to the Iron Age.
👨🏻‍🔬A long journey since my master’s! Huge thanks to @cmpereirasantos Assumpció & Bastien! @ACAD_Research_

Excited to share our new paper! We benchmarked the Twist Ancient DNA kit for in-solution enrichment. It’s cost-effective, robust, and shows no allelic bias, even when pooling libraries!

Great working with @Haarkotter on this project! Excited about the results of applying aDNA to forensic samples! 🦴🧬

[Dr. Haarkötter @Haarkotter]

Ever wondered if aDNA methods could be applied to forensic samples?
Glad to share this work with my fellow @XavierRocaRada done during my stay in @ACAD_Research_
(Spoiler: they could, with magnificent results.)
