Five hundred million years ago, something that was not yet an animal became one. This week, in a lab in Jena, somebody got close to watching it happen.

They found the master switch — the cells that tell a body what to build — inside a comb jelly, one of the oldest branches on the animal tree. Then they moved those cells into a sea anemone from a wholly different phylum, and the anemone grew a whole second working mouth.

The body remembers things older than every empire that ever called us unnatural.

What Survives the Morning: The Burning Doesn't Ask Permission, and Neither Does the Green Coming Up Through It

A lyrical guide to HR survival from someone in the trenches—practical wisdom, real-world advice, and the quiet resilience that grows through workplace fire.

1/5 A fascinating new #ctenophore preprint 🧵 Ferraioli et al. uncover a “ladder-like” neural architecture in the living comb jelly Mnemiopsis and connect it to preserved neuroanatomical traces in Cambrian fossils. But the real importance isn’t the anatomy. It’s what the anatomy implies.

#Ctenophore sampling with the lab on a perfect day around #sunnybergen on the R/V Brattström. Always one of the biggest highlights of the year 🤩. @[email protected] @[email protected]
@xenomatt.bsky.social Beautiful photo! So hard to capture the delicate shapes and iridescence. So fragile too. I have tried to draw / paint them, with little success...

Neural connectome of the ctenophore statocyst

Volume EM and connectome reconstruction of the apical organ of a ctenophore combined with high-speed imaging reveals a neuronal coordination of balancer cilia in the gravisensory organ.

A throwback for Ctenophore Day! If you ever wondered how to pronounce Ctenophore, today is October 4, the 10th month, fourth day and it sounds like ten oh four. They are a phylum of marine invertebrates, like this comb jelly which look a bit like jellyfish, but instead of stinging tentacles they have comb-like cilia (hairs). 🧵1/2

We have received the reviews for our "Neural #Connectome of the Ctenophore Statocyst" paper from @eLife

"This fundamental work significantly advances our understanding of gravity sensing and orientation behavior in the ctenophore, an animal of major importance in understanding the evolution of nervous systems. Through comprehensive reconstruction with volumetric electron microscopy, and time-lapse imaging of cilia motion ... []"
