A huge thanks to our amazing collaborators from @msarscentre.bsky.social, @unibergen.bsky.social and @univie.ac.at who helped investigate how commonly EU ends up in the wrong macro-molecule. 👏

So excited to see @malinkjosavik.bsky.social beautiful work out @bmc.springernature.com 🤩! Check it out to see where the RNA-label ✨EU✨ shows up in our favourite sea anemone and how to catch your organism crafting DNA from RNA labelling tools 🧬👀.

Fantastic news! 👏Congrats James!

Preprint alert! 🧪📣 The latest work of the Steinmetz group @prhsteinmetz.bsky.social on the nutritional control of quiescence in Nematostella is out! Congratulations to lead author @eudaldpascual.bsky.social & @ktgarschall.bsky.social 👏 Read the story ⤵️

Thrilled to see #choanoflagellates on the cover of Science Advances🤩. Our latest work "Electrical signaling and coordinated behavior in the closest relative of animals" out now. Link: www.science.org/doi/10.1126/... 👏 @jeffcolgren.bsky.social @msarscentre.bsky.social

Heat stress drives rapid viral and antiviral innate immunity activation in Hexacorallia The cnidarian class Hexacorallia, encompassing stony corals and sea anemones, plays a critical role in marine ecosystems. Coral bleaching, the disruption of the symbiosis between stony corals and zoox...

1/3 I am very excited to tell you about our latest work where we looked not only into sea anemones but also 🪸
We find in #Nematostella that stress induces not immunity, but also viral replication, actually much faster than the immune response! 🧵

Happy to share that the Gahan lab will be branching out (or more like returning) to working on Nematostella in the near future. Details will follow but for now if anyone is interested in doing a Postdoc or PhD in 2025 on chromatin in Nematostella drop me a message :)
