A near telomere-to-telomere phased genome assembly and annotation for the Australian central bearded dragon Pogona vitticeps AbstractBackground. The central bearded dragon (Pogona vitticeps) is widely distributed in central eastern Australia and adapts readily to captivity. Among

🎉 Another exciting contribution from our lab this summer!

🧬 Nearly complete, gapless genome of the sex-changing central bearded dragon (Pogona vitticeps) shed new light on the mystery of reptile sex determination.

Proud to be part of this collaborative effort!

Hi Enrik, I would love to be part of the feed, check my ORCID: 0000-0003-4120-0140.

Everything starts with few cells and big hopes 🙂

Amazing Lab and topic!!

Update of our preprint on Inter-individual gene expression variability in fishes! We improved statistical analyses of continuous variables, and especially added machine learning on promoters which confirms cis-regulation of organ-specific expression variability, under stronger sequence […]

Great start of the #CABDseminars 2025/2026 with the talk of Miguel Rodriguez de los Santos!

Dr. Rodriguez gave an insight of the studies from his PhD and Postdoc work focused on rate diseases. He was invited by @crisprscan.bsky.social!

Thanks for coming Miguel!

Teaching biology in the old days relied on large posters. Often beautiful and poetic art pieces. When a chair of @genevunige.bsky.social dept, in Geneva, we digitalised our huge collection (catalogue raisonné). Why? I dont' know. The strange feeling these things should not disappear. Yet they will.

PRC2 silences genes by adding H3K27me3 at the right spots in the genome. Our model shows how the nucleic acid-binding domain (NBD) of SUZ12 keeps this activity under control, and what happens when you remove it.

RNA Pol II-based regulations of chromosome folding How transcription and cohesin complexes interact to regulate 3D genome organization remains unclear. Chapard et al. dissect their respective contributions and their interplay in shaping the genome arc...

Pleased to see this study out, combining experimental work from our lab at the @cbitoulouse.bsky.social, in particular by @nathaliebastie.bsky.social and @beckof.bsky.social, and from Laura Chaptal and @alengronne.bsky.social at IGH Montpellier

A genetically tractable non-vertebrate system to study complete camera-type eye regeneration Nature Communications - Accorsi et al. show that the apple snail Pomacea canaliculata has eyes similar to humans and can fully regenerate them. They then developed genetic tools to establish these...

Evolution’s eye game is wild, but mollusks take it to another level

CRISPR in apple snails gives us a new model to dissect how nature rebuilds complex organs like the camera-type eyes we humans possess

It turns out Evolution doesn’t just innovate, it rewinds, remixes, & regenerates

The cover of Nature Genetics July 2025 issue. Digital art of a mouse paw skeletal prep on dark background, digits I to IV disintegrating into viral particles. A caption says “An endogenous retrovirus causes limb malformation”.

Pretty surreal to see my artwork on the cover of Nature Genetics! Big congrats to @julianeg.bsky.social, @stemundi.bsky.social and the others, and thank you Juliane for letting me help bring your research to life visually.
