Cross-species cloning in ants 🐜 These two males belong to different species—but share the same mother. How? Why? To celebrate the print release of our last paper in this week’s @nature.com (issue 8084), here’s a thread summarizing the results. Why? Let’s dive in🧵👇 www.nature.com/articles/s41...

Preprint Alert! 🦥 We produced complete genomes for 2 Xenarthra and placed them in a mammalian comparative framework. We found that Xenarthra harbour the largest number of retrocopies in mammals! www.biorxiv.org/content/10.1...

Another record month for bioRxiv - and further evidence the pandemic spike+dip was just that and growth continues. Thanks to all involved and that includes 🫵

Sujet de stage M2 sur la "dock mussel", cet écotype de moules hybrides qui habite dans les ports. L'objectif est de tester si la dock mussel s’est adaptée grâce à sa variance génétique d’admixture ou si l’admixture n’est que le corolaire du contact secondaire entre les deux espèces parentales.

🐜 Une nouvelle étude révèle un phénomène inédit dans le règne animal : certaines reines donnent naissance à des mâles d’une autre espèce. Ce mécanisme appelé « xénoparité » permet à leurs colonies de survivre. Explications avec des GIF de fourmis ⬇️

A new Science study of ants in Fiji—involving genomic sequencing of over 4000 ant specimens from museum collections—shows that most native species have been in decline since humans first arrived in the archipelago 3000 years ago. https://scim.ag/489mI2o

If you’ve heard about our study on ants producing two different species but are still confused about how it works (and don’t have time to read the paper), this 10-minute video made by @bengthomas.bsky.social is very informative: www.youtube.com/watch?v=Z-O4... Paper: www.nature.com/articles/s41...

PhD opportunity in Bodø! You’ll sequence genomes from invasive and non-invasive slug (A. vulgaris) populations to uncover the molecular basis of invasion dynamics. Supervised by Prof. Les Noble & co-supervisor by me. Fully funded, cutting-edge science, great team. Apply by Sept 21: shorturl.at/zJT06

How many chromosomes can an animal have? In our paper out now in @currentbiology.bsky.social we show that the Atlas blue butterfly has 229 chromosome pairs- the highest in diploid Metazoa! These arose by rapid autosome fragmentation while sex chromosomes stayed intact. www.cell.com/current-biol...

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

Preprint out for myloasm, our new nanopore / HiFi metagenome assembler! Nanopore's getting accurate, but 1. Can this lead to better metagenome assemblies? 2. How, algorithmically, to leverage them? with co-author Max Marin @mgmarin.bsky.social, supervised by Heng Li @lh3lh3.bsky.social 1 / N

Excited to share that I’ve started as Associate Professor at the Technical University of Denmark! 🧑‍🎓 I also received an a NNF Emerging Investigator grant to use genomics + machine learning to study extinction. 👉 PhD & Postdoc positions coming soon — follow for updates! Reposts appreciated 🙏

Our paper on rodent thumbnails is out! Big team effort, powered by museum collections. Turns out, nails can reveal a lot about rodent evolution. Shoutout to Dr. Gordon Shepherd for the wild idea to study rodents thumbs!

Mindblowing research out of the wonderful @isemevol.bsky.social (where I'm delighed to be based for the next three months). Opening line: "Living organisms are assumed to produce same-species offspring [1,2]. Here, we report a shift from this norm". 1. Darwin (1859) 2. Mayr (1942).

How is this possible? This ant can lay eggs of two different species, birthed by the same mother

A common type of ant in Europe breaks a fundamental rule in biology: its queens can produce male offspring that are a whole different species go.nature.com/4mOb5T9

Effort to revive New Zealand’s extinct moa stirs controversy | Science | AAAS www.science.org/content/arti...

@cnrsecologie.bsky.social regrette profondément l'adoption de cette loi à la vision court-termiste & ses conséquences graves sur l’environnement, qui méprise santé & bien-être de la population & le rôle des espèces sauvages dans la prod. agricole. La communauté scientifique n'a pas été entendue.

Re-upping given the moa deëxtinction nonsense from #ColossalBio and it’s cofounder Ben Lamm, it’s nominally about dire wolf “deëxtinction” but applies just as well to moas substack.com/inbox/post/1...

Colossal are likely trying to ‘de-extinct’ the moa by tweaking an emu genome. There’s 62 million years of evolution between an emu and a moa. For context, there’s only 42 MY between humans and howler monkeys. You simply can’t make a human with a GM howler monkey www.newscientist.com/article/2487...

I have serious concerns about Colossal Biosciences, Canterbury Museum & Ngāi Tahu Research Centre pursuing moa de-extinction, incl whether informed widespread engagement w/ Ngāi Tahu rūnanga & South Island iwi was done (many are against de-extinction) www.sciencemediacentre.co.nz/2025/07/09/m... 1/3

Four review requests in my inbox this morning. The one I accepted? Society journal. Our Societies consistently reinvest in our communities in ways the glossies never will. And that makes me invest in them.

New preprint: we advertise DAFNEE, a database of academia-friendly eco-evo-archaeo journals. 1/6 #AcademicPublishing #ecoevo #archaeology #EthicalPublishing #SocietyJournals #DiamondOpenAccess doi.org/10.32942/X24...

In @elife.bsky.social: Effective population size does not explain long-term variation in genome size and transposable element content in animals doi.org/10.7554/eLif... This is the revised version of our manuscript, which will become the final published version !

The DAFNEE database of academia-friendly journals is now using OpenAlex instead of PubMed to find your papers for the author index. That's great especially for #archaeology since most are not indexed in PubMed. Go see the second tab on dafnee.isem-evolution.fr ! @nicolasgaltier.bsky.social 🏺🧪

After 15 years of research, we're excited to share that the causative agent of White-Nose Syndrome/Disease is actually two cryptic fungal species, each showing host specialisation. We've also traced the introduction to North America back to Podillia, Ukraine.

Four AI-generated "articles" have now disparaged me, "Colleagues and experts in the field have expressed concerns about the consistency and scientific integrity of his work" gripeo.com/02/vincent-l...

The Last of Us may be over for now, but fungus pandemic news endures. Here's my story on how white-nose disease, which has battered North American bats, may have more devastation in store. 🧪 Gift link: nyti.ms/4mGRyV8
