Excited to finally see my PhD work published! We identified specialized cells in jellyfish and coral larvae with shared features and potentially linked to settlement regulation.

Our chromosome-scale genome assembly of Nanomia septata, a siphonophore -
doi.org/10.1101/2025...
. Much larger than many other cnidarian genomes, fewer chromosomes, and highly rearranged. No smoking gun for how they achieve complex colony-level organization. Great work Namrata Ahuja and friends!

It's publication day of my first book: The Tree of Life. The tree of life is a time machine that can take us back 4 billion years to meet our most distant ancestor. It is the magic that lets us tell the origin stories, beginning with this ancient relative, of everything from mushrooms to man.

Intriguing findings from our Sendai collaborators Ruka Kitsui and Ryusaku Deguchi. While C. hemispherica spawns at dawn, Clytia IZ-D species spawns at dusk. This is not triggered by dark but, unexpectedly, by light-mediated extension of an autonomously-running 20h cycle.

That was another nice find -thanks John. We love Metchnikoff too -especially for his substantial contribution to invertebrate embryology, including of course this !

How come PKA signalling has opposite roles for oocyte maturation in vertebrates compared to many other species? We unpicked this “cAMP paradox” in a cross-species collaboration, charting phosphorylation site evolution of the key regulator ARPP19. Meneau et al. DOI: 10.1242/dev.202655

Would you like to join us in screening these tags in diverse species? Please get in touch. We're happy to share the constructs for generating mRNA, and will be happy to include new species –and new co-authors– in our comparative study. 3/4

Looking for a tag to localise fluorescent proteins to the plasma membrane? Unsure which tag might work in your species? We generated a toolkit of 11 membrane-localising tags, which can be screened rapidly by microinjecting mRNA in your species of interest. 1/4
