🌍 New research in The Lancet Microbe, co-authored by Carolee Bull, explores how microbiomes connect human, animal, and environmental health through a One Health lens.

A more scientific thread will come soon!
Finally my heart goes to the post-doc dreamteam: Hanin Ahmed, Alex,Evelyn Todd, Ophélie Lebrasseur and my wonderful officemate Kuldeep - you made these years better by being the most supportive people ever.
Finally, as research is team work, thanks Andaine Seguin-Orlando, Clio Der Sarkissian, Patrice, Ameline, Sylvie, Catherine Thèves, Charles Stépanoff, Etienne Patin, Lluis Quintana-Murci as well as the full CAGT team for your help, work and input in this amazing project.
I learned so much through this project on the technical, theoritical and practical point of view, and I hope people will also learn a bit from our paper about what can be done with ancient DNA when you take the time to dissect every aspect of a story.
Being able to actually make the archeological record, the biological and genomic informations communicates together was thrilling, and i'm really thankful for this opportunity. Thanks goes to my PI, Ludovic Orlando, and the archeologist who dedicated 15+ years of his lige to Yakutia: Eric Crubezy.
I'm really really proud of my new paper:
It is the perfect ending of almost 3 years of postdoc in the CAGT and the fruit of a very learnful collaboration.
The main reason is that we submitted the paper in 2024 before Rodriguez-Varela paper came out!
Don't hesite to reach to me, I'm the postdoc who led the study and did all the analyses (genomic and metagenomic), and it's still (fairly) fresh in my mind
Happy to discuss with you about it!

Pie-grièche écorcheur (Lanius collurio). Un de nos plus jolis passereau, qui - comme beaucoup de nos beaux passereaux - passe l'hiver en Afrique. Ici c'est le mâle, bien reconnaissable à son masque de petit voleur. C'est aussi un habitué de nos campagnes, car il a besoin de buissons touffus pour son nid et de milieux ouverts pour chasser. Il doit d'ailleurs son nom à sa petite manie de constituer des réserves en empalant ses proies (gros insectes et mêmes petits vertébrés) sur des tiges ligneuses ou des barbelés. . Red-backed Shrike (Lanius collurio). One of our prettiest passerines, which - like many of our beautiful passerines - spends the winter in Africa. This is the male, clearly recognisable by his little thief's mask. It is also a regular visitor to the countryside, as it needs bushy areas for its nest and open spaces to hunt. It owes its name (in French) to its habit of building up reserves by impaling its prey (large insects and even small vertebrates) on woody stems or barbed wire.
Rossignol philomène (Luscinia megarhynchos). Petit migrateur, chanteur incroyable de par la diversité des sons qu'il produit et parce que c'est un chanteur de nuit. Il ne s'arrête jamais et il illumine de ses airs flûtés et sonores les marches du soir dans la campagne, depuis les buissons épais proche des fossés humides où il aime faire son nid. Nightingale (Luscinia megarhynchos). This small migratory bird is an incredible singer because of the diversity of sounds it produces and because it is a night singer. It never stops, lighting up evening walks in the countryside with its flutey, sonorous tunes from the thick bushes near the damp ditches where it likes to nest.
With all the sun we had in Paris, I want to share pics I took of two birds I strongly associate with spring and summer.

Still relevant today... Counter the weaponization of genetics research by extremists.
Geneticists must rethink how they conduct their research and how they communicate results. www.nature.com/articles/d41... @sramach.bsky.social @cschlebu.bsky.social @haam-community.bsky.social #genetics #research
"I study animals from the past, and they should stay in the past," as I said in this interview, and "the idea that they can fix that [the extinction crisis] with gene editing is missing the big picture.”

The International Day of Women and Girls in Science is always a bittersweet one: it is time for awareness of the benefits of gender equality to advance science, but when we are promoting scientific careers... what careers are those?
A l'occasion de la Journée des femmes et des filles en science, le CRSA tient à mettre à l'honneur ses ingénieures, techniciennes, doctorantes, post-doctorantes, enseignantes -chercheuses, chercheuses et gestionnaires 👩🏼🔬👩🏻👩🏽🎓
Between 2019 and 2023, researchers paid $8.968 billion to make papers open access. Imagine what else could be done with this money if it wasnt paid to for profit publishing companies...

I don't understand researcher using IA art to promote their work, when the discussion in academia about plagiarism, citation, giving credits to people works and idea is so important
"Genetic data are not produced in a political vacuum, can be used and abused in political agenda, and have serious implications in the treatment in marginalized communities [...] whole lives are condensed to a few data points, an inherently dehumanizing process"
Last but not least, I am still baffled by the fact that every scientific conference/event is not at least veggie. Firstly, it's the best way to be inclusive of a lot of religion, and secondly, if even scientists don't apply what's recommended in the papers, who's going to? 10/10
Also, looking back on these 10 years of vegetarianism, I can confidently say that it is much easier to be vegan now than 10 years ago. Even French chefs are coming around to the idea of vegan gastronomy, as we recently got a vegan restaurant with 3 Michelin stars 9/X
For now, I'm taking the same flexi approach to dairy: no dairy at home, but I'm not too strict about it outside. But I do tell my boyfriend that I'm dairy free, and once again I see more options opening up around me. I know that with my French family, no cheese will be a lot harder than no meat. 8/X
Recently, I've spent time in the countryside next to a herd, I've heard cows crying heartbreakingly loud for weeks after their calf has been taken away to be killed. And I could no longer buy cheese. I also found out through research that cheese is really not good when it comes to sustainability.7/X
The simple fact that I am a veggie has made my friends and family consider more veggie options. A recent ex: in a restaurant that usually has one menu, my mum (a meat lover) asked for a veggie menu instead of just asking for no fish, because my partner and I were asking for that option anyway. 6/X
As soon as I told everyone I was a veggie, veggie options started popping up all around me. Fun fact: on a trip to the Alps with classmates, we had tartiflette - and the veggie option was so much better that all the non-vegans got jealous and asked for the veggie option the next day. 5/X
So, after less than a year as a flexi, and another party with frozen pizza with meat on it that was definitely not from a small local farm in France, I switched to a full veggie diet. 4/X
I quickly realised that when you say you're "cutting down" on meat, you're still eating a lot of it, and often not of the quality and origin you wanted (especially when you go out, as people assume you don't mind eating meat). 3/X
In 2014, I tried to become a flexitarian for environmental reasons. I said I wanted to eat less meat, but only high quality meat from small local farms. 2/X
