Pleased to share our latest paper led by @tomlewin.bsky.social, now out in @currentbiology.bsky.social! We present the first chromosome-level genome of a phoronid and show that shared chromosomal fusions unite phoronids and bryozoans as sister groups.

Cette éponge carnivore (Chondrocladia sp. nov.) fait partie des 30 nouvelles espèces découvertes autour des îles Sandwich du Sud.
"Nous n'avons analysé que 30 % des échantillons prélevés. La confirmation de ces 30 nouvelles espèces témoigne donc d'une immense biodiversité encore inexplorée"

Our study, just published in #ScienceAdvances and funded by @hfspo.bsky.social, explores the post metamorphic cell composition of the sea urchin juvenile, revealing that its body is head-like. Long considered brainless creatures, they’re all brain instead!

Single-nucleus profiling highlights the all-brain echinoderm nervous system
A sea urchin is a head with a brain-like organization and a vertebrate-type retinal signature.

How can we see the cells that make up a living organism? Membrane-localising tags can drive fluorescent proteins to the cell's outer membrane, making their outlines visible. But the tags don't work well in all organisms. How do you find one for your species of interest? 🧵

🔬 Limb regeneration depends on regenerative signaling center cells — but how do these cells influence others to proliferate, migrate, or differentiate?
We’re recruiting PhD or Postdoc candidates to explore this with our collaborator @osvaldo-chara.bsky.social !

Abstract. To limit transposable element (TE) mobilization, most eukaryotes have evolved small RNAs to silence TE activity via homology-dependent mechanisms
