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.

A Nobel-winning scientist of great modesty and humour, John Gurdon died on 7 Oct. Not only did he make a discovery that laid the foundations for stem cell research, he also created one of the best environments for research at the Wellcome/CRUK Gurdon Institute wellcome.org/news/sir-joh...

Our latest: combining single-cell RNA-seq from 16 species and HCR validation, we show that monoaminergic neurons share a conserved transcriptional identity across Bilateria. In contrast, we find no evidence for this program in non-bilaterian metazoans. www.biorxiv.org/content/10.1...
Monoaminergic neurons share transcriptional identity across Bilaterian animals
The evolutionary conservation of cell types over deep time has long been theorised but remains difficult to demonstrate. Monoaminergic neurons, which produce molecules such as serotonin and dopamine, ...

This is two stories in one: a case study/cautionary tale on developing genetic tools in new organisms, and the first hint at a gene regulatory network for choanoflagellate multicellular development (which turn out to involve a Hippo/YAP/ECM loop!) A 🧵
