🪼 Your tax dollars paid a scientist to squeeze jellyfish through cheesecloth. Osamu Shimomura processed tens of thousands on an NSF grant to understand why they glow. He found a protein that glowed green under UV light. Called it "green protein." Nobody cared. For decades.

The Hoffman Lab at Yale is hiring! We’re currently recruiting for a Lab Manager and Post-Graduate Research Associate positions. If you're interested in understanding the function of neurodevelopmental disorder genes in the developing brain using #zebrafish, we'd love to hear from you! #researchjobs

Astrocytes do so much more than any of us thought - they even communicate among specific brain regions across hemispheres! The journey to this paper spanned nearly a decade, but I'm most excited to see what everyone else does with the tools we've built. There's so much for all of us to explore!

Communication between distant brain regions is mediated by plastic networks of gap junction-coupled astrocytes.

🚨 Turning on heart regeneration through immune modulation? Led by @kcinc.bsky.social, we show that activating pro-regenerative macrophages induces Granulin, a key driver of cardiomyocyte proliferation and scar resolution in medaka, now published in @pnas.org 💔➡️❤️ www.pnas.org/doi/10.1073/...

I created this collection of common brain models in neuroscience, all to scale Across species, brains share fundamental principles and many homologous regions But as size increases, complexity and connectivity change. We need the full spectrum, from flies to rodents, non-human primates, and humans

A scaled collection of brains from common neuroscience model organisms arranged side by side. From left to right: a large human brain and a smaller macaque brain on the top row; below them progressively smaller brains from a marmoset, rat, mouse, zebrafish, and a tiny Drosophila (fruit fly). A coin provides size reference. An inset shows a small, irregularly shaped brain organoid.

Very happy to share this study from our group and colleagues now out in Science! We found that in zebrafish, before the immune system is mature, gut epithelial cells perform immune functions by producing the cytokine IL-22 to shape the microbiota to promote early life gut function #Zebrafish #Gut

IL-22 from enteroendocrine cells promotes early-life gut motility in zebrafish through the microbiota

The gut microbiota, immune system, and enteric nervous system interact to regulate adult gut physiology. However, the mechanisms establishing gut physiology during development remain unknown. We repor...

I defended my PhD 10 years ago today. That was the least remarkable thing that happened that day. Sharing something I wrote about it last year. Since then "the horrors persist but so do we." And with dignity.
