Congratulations, Océane!

Hi, can someone point me to good commercial polyclonal anti-FMRF amide antibody, which is not from rabbit? Ideally, tested on cnidarians. Thanks in advance!

Notch coordinates self-organization of germ layers and axial polarity in cnidarian gastruloids Dissociation and reaggregation experiments in several animal systems have revealed the stunning capacity of self-organization. Reaggregated early gastrula cells (here called gastruloids) of the sea an...

Sanjay's amazing story is available on www.biorxiv.org/content/10.1... Congratulations to @sanjay-n.bsky.social, @ulrichtechnau.bsky.social and everyone else 🎉

Congratulations Venky!

Congratulations to Dr. Paul Knabl @paulknabl.bsky.social Fantastic work and excellent defense!

Congratulations! 🎉

β-catenin-driven endomesoderm specification is a Bilateria-specific novelty - Nature Communications Lebedeva et al. show that unlike Bilateria, the embryo of the cnidarian Nematostella specifies its endomesoderm in the β-catenin-negative domain. In contrast, subsequent β-catenin-dependent axial patt...

Thanks Max (although it's primarily @emmanuelhaillot.bsky.social who deserves the congratulations here). May I suggest that you also look at this paper www.nature.com/articles/s41... - the fit together really well.

Segregation of endoderm and mesoderm germ layer identities in the diploblast Nematostella vectensis - Nature Communications Recent work suggested that diploblast embryos (Cnidaria) may have germ layers that are similar to those seen in bilaterians, but how these are specified remained unclear. Here, they use scRNA-seq and ...

The genomic origin of the unique chaetognath body plan - Nature Genomic, single-cell transcriptomic and epigenetic analyses show that chaetognaths, following extensive gene loss in the gnathiferan lineage, relied on newly evolved genes and lineage-specific tandem duplications, not caused by a whole-genome duplication event, to shape their distinctive body plan.

Loss of Twist impairs tentacle development and induces epithelial neoplasia in the sea anemone Nematostella vectensis The basic helix-loop helix transcription factor Twist plays diverse roles in mesodermal development across bilaterians, but its function in cnidarians remains unclear. Here, we investigate the role of...

Depletion of a neural cell adhesion molecule disrupts both epithelial and germ layer identity in sea anemone embryos Assembly of cells into epithelial layers marks the early steps of tissue organization and embryonic development in most animals. Although several conserved proteins are known to be essential for epith...

Ctenophores possess a unique aboral organ that acts as a multisensory center, controlling complex behaviors. We’ve now created a ctenophore model integrated with our 3D volume EM data. Puts it into perspective.

Gastruloids employ an alternative morphogenetic route to generate a posterior body axis on adherent substrates Morphogenesis emerges from the integration of genetic programs with environmental signals, yet studying this interplay in embryos remains challenging due to the inherent complexity of embryonic system...

BEHOLD! One of Earth's greatest lineages of life: the lil wiggle arm guys, Meteora.

These single-celled critters, originally found in deep-sea sediments, are SO DIFFERENT from other lifeforms on Earth that they're likely in their own kingdom (as in, the Animal Kingdom, the Plant Kingdom etc). 🧪🌿

Planar cell polarity coordination in a cnidarian embryo provides clues to animal body axis evolution The jellyfish embryonic body axis is globally coordinated by conserved planar cell polarity (PCP) mechanisms and oriented by localised Wnt3 in two steps, highlighting PCP’s role in animal axis evoluti...

I don't know... Depends on the context in which you have been cited. Imagine a sentence like "Prof. Moran's ridiculous claims that..." 😜

Congratulations!

Thanks, you are very kind. We'll keep trying.

Congratulations 🎉

Uri does really cool stuff in Hydractinia

Thanks, Uli!

Thank you!

Thanks, Uri!

Thanks, Yehu!

This long, difficult, but super cool project was funded by the @fwf-at.bsky.social, and led to David winning his own ESPRIT grant! Thanks!
