- Reposted by Aissam IkmiOnly a few days left for abstract submission at the brand new EMBO|EMBL Symposium Collectivity in living systems: emergence, function and evolution. We have stellar speakers in cell, animal collectives & beyond @priscaliberali.bsky.social @icouzin.bsky.social @ricardsole.bsky.social Join us!
- Reposted by Aissam IkmiOur Special Issue on Lifelong Development #LifelongDevSI is now complete! Guest edited by Meri Huch and Mansi Srivastava, it contains 26 research and review-type articles. On the cover: the dorsal vasculature of an adult zebrafish's first gill arch. See Preußner et al. doi.org/10.1242/dev....

- Great having you at @embl.org, Michel! Inspiring science, great discussions, and a fantastic perspective on quantitative evo-devo.
- Had the pleasure of working with @mohannad-dardiry.bsky.social to rethink what it means to develop for life. Many thanks to @dev-journal.bsky.social! @embl.org #LifelongDevSI
- Phenotypic plasticity as the foundation of lifelong development In this #LifelongDevSI Hypothesis, @mohannad-dardiry.bsky.social & @aikmi.bsky.social (@embl.org) challenge the paradigm of organismal terminal differentiation doi.org/10.1242/dev....

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!)

- Reposted by Aissam IkmiLatest paper elifesciences.org/articles/107... closes an important cycle in our efforts to study regeneration: week-long recordings allow us to observe the behaviour of cells during the entire course of regeneration in a crustacean leg – bright objects in movie are fluorescent nuclei of cells. 1/6

- Reposted by Aissam IkmiCtenophores 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. Check out our recent work here: www.biorxiv.org/content/10.1... #ctenophores #volumeEM

Paul showed that BMP signaling is active in the diffuse nervous system of the sea anemone Nematostella and the box jellyfish Tripedalia. Moreover, suppression of BMP signaling in Nematostella leads...
