NEW GRANT OPPORTUNITY! Ever wanted to travel to a different lab to learn more? Or expand your knowledge and experience in the field? #IZFS has a new grant opportunity for you! Read more about the Knowledge Exchange Grant here: www.izfs.org/awards/knowl... #ZebrafishGrant

"The importance of a model is choosing one that allows you to address the question that you’re setting out to address." Sage advice from Prof. Judith Eisen (University of Oregon), Pioneer of Zebrafish Research & 2024 George Streisinger Award Winner. #ZebrafishFunFacts 🧪

How did octopuses evolve novel traits? Rishav Mitra, Richard Han, Trey Scott, et al serendipitously discover a unique ribosome adaptation that increases the accuracy of protein synthesis and evolved alongside their elaborate nervous systems vs deep sea relatives. www.biorxiv.org/content/10.6...

No better way to head to #EZM2026 than with a freshly published success! Our eLife paper is now out: elifesciences.org/articles/107.... We show optimised prime editing in zebrafish for precise DNA substitutions and insertions. Huge thanks to the fantastic team #Zebrafish #GenomeEditing #eLife

Optimised genome editing for precise DNA insertion and substitution using prime editors in zebrafish

Nickase and nuclease Prime Editors offer complementary routes for precise zebrafish genome editing, balancing accuracy for substitutions with efficiency for short insertions.

We're excited to present a single-cell atlas of vertebrate cranial motor neuron development, the first story from my postdoctoral work in the Moens lab, up now on bioRxiv!

How do dozens of distinct muscles emerge from the same pool of precursor cells? Our new Science Advances paper uncovers the developmental logic that coordinates myoblast identities to build diverse muscles. 📄 www.science.org/doi/10.1126/... #DevelopmentalBiology #Drosophila #Muscle

Spatiotemporal control of myoblast identity drives muscle diversity in the Drosophila leg

This study reveals how muscle diversity arises in flies, enabling the complex movements that drive animal behavior.

I am excited to announce the latest paper from our lab, published in Science ! In this study, we show that thalamocortical-like circuits in the zebrafish brain process sensory information hierarchically across topographically organized forebrain circuits.

Hierarchical sensory processing in zebrafish thalamocortical-like circuits

Thalamocortical projections shape the functional regionalization and parallel sensory computations across the mammalian cortex. However, the principles of thalamocortical computations in non-mammalian...

Dear Friends, I just published an insightful review on neural crest evolutionary origin and later transformations. “Co-option and innovation in neural crest evolution”: www.science.org/doi/10.1126/...

Co-option and innovation in neural crest evolution

Neural crest evolution reassembled ancient programs in pigment cell lineage, resulting in vertebrate innovations.

What if an embryo made immune cells before it finished building the tissue they usually come from? In our new preprint, we show that annual killifish embryos specify neutrophils before germ layers are fully resolved. www.biorxiv.org/content/10.6... Huge thanks to my PI, @ohnolog.bsky.social ! 🧵

Early immune cell development precedes gastrulation in annual killifish

During embryogenesis, cell types arise in a predictable order because developmental regulators act sequentially. But how evolutionary changes in morphogenesis reshape the signaling environments that a...

Annual killifish continue to surprise us: they make neutrophils before almost every other cell type, even before gastrulation. Neutrophils usually arise from the lateral plate mesoderm (forming in cyan), but in killifish they are already patrolling around the embryo in gold. tinyurl.com/killiphil

We take for granted that our hands have two sides and can articulate in an endless number of ways. But what about a fish’s fin? Can a fish know something “like the back of its fin,” or have its future told with a fin palm reading? Check out this bluetorial to find out 👇🧪🧬🐟 doi.org/10.1101/2025...

Excited to share this new pre-print from the fantastic @kelsiehunnicutt.bsky.social! Kelsie put together a thoughtful and thorough review on hybridization in animal evolution: ecoevorxiv.org/repository/v.... She tracks notable shifts in perspectives on the study of hybridization through time.

Some great news, Ensembl has released the GRCz12tu and the GRCz12ab annotations on their beta release site, so now the genes can be looked at in a genome browser. You can load up either one (plus a second TU genome) here: beta.ensembl.org/species-sele... #zebrafish

Using light-activated CRISPR in zebrafish, we triggered synchronized DNA breaks and track the repair process. ⚡🐟⚡

These images show live embryos of animals (jellyfish, crustacean, worm, sea urchin, sea squirt, beetle) and one of animals closest single-celled relatives. They were captured taking advantage of fluorescent proteins localised on the outer membrane of cells, allowing us to observe cell outlines. 1/9
