Our paper on the role of neurons in Nematostella head regeneration is now out at @currentbiology.bsky.social Big thank you to all collaborators, it was a pleasure!

Ectopic head regeneration after nervous system ablation in a sea anemone
Via genetic ablation of neurons, Mazloumi Gavgani et al. show that the nervous system
is essential for defining axial polarity during whole-body regeneration in the sea
anemone Nematostella vectensis.

Happy Ctenophore Day!
These glowing ocean drifters look like jellyfish but aren’t! They’re comb jellies, shimmering creatures that light up the sea with rows of beating cilia 💙🌈
Which species can you identify? 👀 Most are raised in @pawelburkhardt.bsky.social lab

Very excited to share that we developed a new non-invasive way to predict spawning time in Octopus vulgaris. Until now, we had no means of knowing when a female was going to spawn, which made planning of our experiments very difficult. But now we solved it! www.biorxiv.org/content/10.1...
