Alors que les mesures susceptibles de réduire les émissions de gaz à effets de serre de manière massive et immédiates continuent à se faire attendre, on voit un regain d'intérêt, notamment sur l'affreux Twitter, pour les techniques d'élimination de carbone atmosphérique et de capture et de stockage de carbone.

Dans mon bureau à Orléans, je suis entouré d'experts sur ce sujet - consultez-les!

En attendant, voici ce qu'on peut lire dans le rapport du #GIEC sur le sujet.

Our preprint describes how #EffectivePopulationSize affects #AminoAcid usage. https://www.biorxiv.org/content/10.1101/2023.02.01.526552v2. Within highly exchangeable pairs of amino acids, high Ne species are able to prefer #arginine over #lysine, and #valine over #isoleucine. This matches #thermophile preferences, as expected from theories of marginal protein stability at mutation-selection-drift balance. 1/6

The #ETI2023 workshop has ended ! A week-long whirlwind of ideas, discussions, debates and chalk. Thank you to everyone involved: participants, staff, funders. It was wonderful to see so many viewpoints contrast and resonate. Stay tuned for more ETIs news in the near future !

Some viruses do this crazy thing where the genome is split into different fragments, which are then each transmitted separately. We show that this can evolve quite easily by selection for 'cheating'. https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.3002092

Our latest #preprint develops a new metric of #CodonAdaptation (not just #CodonBias) to measure the kind of #EffectivePopulationSize that matters to #NearlyNeutralTheory, and uses it to discover that #NaturalSelection prefers high #IntrinsicStructuralDisorder https://www.biorxiv.org/content/10.1101/2023.03.02.530449v1 1/6

Pourquoi je me suis retrouvée à interrompre une conférence et me faire traiter d’« anti-science » sur les réseaux sociaux.
Le contexte : l’AFIS, qui se présente comme une association « d ‘information scientifique » organisait jeudi dernier une conférence publique sur « glyphosate, santé, environnement » dans une magnifique salle gentiment mise à disposition par la mairie du Ve arrdt.

Very happy to see new paper in final format out! How development affects evolution. A thread: 1/10

(please share !) We are recruiting a postdoc to work on the joint evolution of enzyme features and metabolic networks. We know a lot about how enzymes work and use this information in mechanistic models to understand simple and universal genotype-phenotype maps. Starts ASAP

Some of you may have seen Elon Musk's endorsement of Robert F. Kennedy Jr.'s crazy antivax conspiracy theories today.

Over at post.news, I just posted a long-form piece about this, and about how science education needs to adapt to online disinformation.

Please a look. If you like it, boost it there or here or — if you dare — over on the birdsite.

'In #malaria parasites, sexual reproduction coincides with transmission to the vector host. Sex determination is non-genetic, with each haploid parasite capable of producing either a male or a female gametocyte in the human host. The hierarchy of events and molecular mechanisms that trigger sex determination and maintenance of sexual identity are yet to be elucidated.'

What would be a greater opportunity for my first post here other than announcing my first (first-author) paper? A thread:

Despite the increasing attention on the oral microbiome, until now we didn't have a good idea about how it evolves in the wild! In our new publication with Adrian Forsythe, @jfy133, Jaelle Brealey, Christina Warinner & Katerina Guschanski we investigate exactly this! 🦷🦠 https://doi.org/10.1093/molbev/msac263

RT @TimKietzmann@twitter.com

Ran one of our essay questions through @OpenAI@twitter.com's new chatbot. Essays are dead.

Back to hand-written exams I guess. Sigh.

As a "fun" side project, I'm the lead author of the PopGen.jl suite of population genetics packages in the Julia programming language. It's ⚡FAST⚡ and 📒well documented 📒, written for easy onboarding. Have a look, try it out, let's chat!

https://github.com/biojulia/popgen.jl

How fast? Well, pairwise FST can be >600x faster than R::hierfstat on the same data. That's the difference between waiting 1 second and 10 minutes!

Here's a lil thread of things I *wish* somebody had told me when I started advising #STEM #gradstudents as a lab head, #PhD program director, and grad school conflict-resolution officer. Or maybe they did and I wasn’t listening? 🧵
