Well, our retirement lasted four months and it's definitely time for a re-introduction of sorts! ZR! covers highlights of all things #zebrafish and other cool teleost species. We act as a resource hub for questions/queries from the community while celebrating all those that are part of it! #RockOn 🧪
Merry Fishmas, shoalmates! We hope you have a lovely festive season 🎄🐟 🧪

New publication!
Our first zebrafish paper in collaboration with Jeff Amack's lab was accepted by @devdynamics.bsky.social. Our work shows that in zebrafish, a Fhod3 paralog is needed for normal cytoskeletal maintenance in developing skeletal muscle.

Important lesson for fish researchers (tbh, any researcher):
Make your solutions fresh! (e.g. "alarm substance stored overnight at −20°C elicited a diminished alarm response compared to fresh alarm substance of equivalent dilution")

I am delighted to introduce our new Centre of Excellence in Immune-Endothelial Interfaces (IMMENs) funded by the Research Council of Finland.
www.helsinki.fi/en/researchg...
I will be recruiting two postdocs early next year. One image analyst and one biologist interested in working on lymphatics!

Centre of Excellence in Immune - Endothelial Interfaces (IMMENs) | University of Helsinki
The overarching aim of IMMENs, a Research Council of Finland funded Centre of Excellence, is to understand how local immune responses are regulated at the lymphatic endothelium-immune cell interface.

Did you know the last common ancestor of #zebrafish and humans was ~450 million years ago? A whole genome duplication event (3R) occurred early in the teleost fish phylogeny. Despite this event, zebrafish and humans have about the same number of chromosomes. #ZebrafishFunFacts 🧪
