Zebrafish Rock!

@engertlab.bsky.social et al. used “head-fixed and free-swimming larvae to assess their capacity to detect and follow the direction of optic flow, as well as to characterize swimming speed patterns and individual tail bout properties following administration of the two Carbadiazocine photoisomers.”

Thanks for sharing! We are big fins of yours 😊

“Together, these findings establish a comprehensive assessment of zebrafish models that reveal both shared core functions and specialized roles of ATXN1 family genes in development, neuroimmune regulation, sensorimotor behavior, and retinal signaling.”

And they passed! Congrats, Dr. Zelle @srzelle.bsky.social 🎉 #PhDone

Special congrats to the outgroup! #GarsRock

Congrats, @bailinwu.bsky.social 🎉 #YouRock

We’ve got FOMO! How’d it turn out @srzelle.bsky.social?!?

For those interested, Research Investigator role available in Pediatric Hematology at University of Michigan Medicine, within the zebrafish-friendly lab of @clot1.bsky.social! careers.umich.edu/job_detail/2...

"These results provide the first evidence of a number-space association in zebrafish and demonstrate that number-space mapping extends to a basal vertebrate lineage."

Screenshot of the left panel of the ZFIN website following the query for 'Phenotype' and 'otoliths'. It shows 'Phenotype gene', 'Phenotype tag', 'Phenotype Statement' and 'Stage'

You can further restrict the query based on 11 different categories including the 'Gene', 'Phenotype tag' (e.g. abnormal, normal, ameliorated or exacerbated), 'Phenotype statement' (e.g. otolith decreased size, abnormal) and by developmental stage among others. Go ahead and give it a try! 🐟🪨 3/end

Screenshot of the ZFIN website with the 'Phenotype' search query of 'otoliths'

As an example, we will search for 'otoliths' or ear stones (Since #ZebrafishRock). These calcium-carbonate biocrystals are responsible for auditory and vestibular processing as the fish explores its environment. Here's the search query for a reference: zfin.org/search?categ... 2/n

Screenshot of the ZFIN website with the search query set for phenotypes associated with 'otoliths abnormal'

Did you know you can search by phenotypes on ZFIN (zfin.org)? From the dropdown, select 'Phenotype' and try inputting any structure or behavior into the search bar. We'll give an example in this thread. And stay tuned for more tips and tricks under the hashtag: #ZFINtips! @zfinmod.bsky.social 🧪 1/n

We still didn't have any luck finding it but it sounds like something @stainierlab.bsky.social might have made or have in their facility? You could try emailing Didier: zfin.org/ZDB-PERS-960...

"We demonstrate that the medial facial lymphatic vessel requires cartilage of the hyoid arch for development and identify pregnancy-associated plasma protein A2 (pappa2) as a possible candidate for mediating the cartilage-lymphatic interaction."
