Super cool work on medaka by @ewanbirney.bsky.social and colleagues www.cell.com/cell-genomic...
Includes an excellent summary from Ewan via linkedin... and I maintain that 'humans aren't special' 😊 www.linkedin.com/pulse/little...
And it's out indeed! Huge congrats to @josanesousa.bsky.social, @gabrielalima19.bsky.social, @perezlouise.bsky.social & Hannah Schof! A true tour-de-force that highlights how emerging model systems can shed new light on long-standing macro-evolutionary questions. Go #axolotl, #polypterus #zebrafish!
Figure depicting the four classes of important questions that frequently arise when using research organisms to study biomedical questions and translating findings to humans. a, How to predict disease–gene or function–gene relationships across species? Diagram depicts genes in each species associating with specific functions, diseases and phenotypes. b, How to identify functionally equivalent molecular components across species? Diagram depicts finding the most equivalent gene, pathway or expression module or phenotype between species. c, How to infer perturbed molecular profiles across species? Diagram depicts gene expression in each species as a result of taking a particular perturbation like a drug. d, How to map equivalent cell types and cell states across species? Diagram depicts alignment of cell types across species. This Perspective comprehensively lays out the landscape of recent and state-of-the-art data-driven strategies, including those that leverage artificial intelligence and machine learning (ML), for answering these questions.

Why are some species smaller than a paperclip while others grow longer than a school bus? How is body size evolution governed in animals? Out now in @pnas.org we tackle these longstanding questions through a genetic lens using my favorite group of fishes as our model!! www.pnas.org/doi/10.1073/...

Meet the mesmerizing new addition to our Into the Deep/En lo Profundo exhibit, rough snailfish! These ethereal charmers live in the benthic zone, a scientific term for the seafloor.
Congrats @liujuan.bsky.social, our very own @zzhou32.bsky.social and all co-authors! Fintastic work!
Update of our preprint on Inter-individual gene expression variability in fishes! We improved statistical analyses of continuous variables, and especially added machine learning on promoters which confirms cis-regulation of organ-specific expression variability.

Schematics depicting the dorsal and ventral sides of fins and limbs
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...
The Braasch Lab @fishevodevogeno.bsky.social will soon post a position to replace manager of our *Ancient Fish Facility* at Michigan State. Looking for aquaculturist excited for unusual 🐟 species (gar, bowfin, paddlefish, polypterus) + zebrafish. Pls send candidates our way (DM or braasch@msu.edu)!
At #PASEDB we embrace all organisms. Each one has its own evolutionary trajectory that makes life so diverse 🌈🦄

deep-sea adaptations have evolved independently in several groups. Eye shape: A prominent morphological example is the evolution of an elongated tubular, barrel eye to maximize photon capture in several deep-sea groups. Groups, where tubular eyes are common, are marked by a black square and a tubular eye scheme; groups with one/ few cases of tubular eyes but where the majority of species have a camera-type eye are marked with black dots (i.e. anglerfishes and dragonfishes). Retina: Rod-only retinas are a common feature of many adult deep-sea fishes. In other cases, they possess the typical duplex retina with cones (green cells) and rod cells (grey cells). Multibank: In some species, the rod cells are organized in multiple layers, forming a multibank retina, while other deep-sea fishes have the typical vertebrate single layer. Cone/rod id: Some deep-sea fishes have photoreceptor cells with an uncertain id that is intermediate between rods and cones due to a mismatch of the opsin and phototransduction cascade genes (e.g. in Scopelarchidae and Evermanellidae; Aulopiformes), or thanks to the presence of transmuted cells (i.e. rod-like cones in Maurolicus spp.; Sternoptychidae; Stomiiformes). Rhodopsins: Like other vertebrates, most lineages only have one rhodopsin (rh1) gene. Two rhodopsins are found in pearleyes (Scopelarchidae; Aulopiformes), and hatchetfishes (Sternoptychidae, Stomiiformes), and more than three rhodopsin genes are found in lanternfishes (Myctophiformes), spinyfins (Diretmidae), and tube-eye (Stylephoriformes). Photos (from top to bottom): Threadfin dragonfish, Echiostoma barbatum (Stomiiformes; photo Zuzana Musilova); pearleye, Benthalbella sp. (Aulopiformes; photo Zuzana Konvičková); and silver spinyfin, Diretmus argenteus (Trachichthyiformes; photo Vít Kaufman). Based on data from Collin and Partridge (1996), De Busserolles et al.
