Dearest shoalmates: Please consider posting a comment to the NIH regarding the Strategic Plan that includes reducing funding for animal research. Responses from the research community are currently greatly underrepresented compared w/ advocacy groups opposing animal experimentation. 🔗 below ⬇️ 1/2

Happy fluorescence friday! And I'm very excited to cellebrate it with my new paper "Deep-learning deconvolution and segmentation of fluorescent membranes for high-precision bacterial cell-size profiling", out yesterday in @commsbio.nature.com ! rdcu.be/fkg2G

ICYMI… Huge congrats to Prof. David Grunwald @utah.edu for winning this year’s George Streisinger Award from IZFS! #RockOn 🐟 #zebrafish

New preprint from my lab! Will Anderson developed a transgenic #zebrafish ubiquitously expressing an optogenetic FGF/ERK activator. We're having a lot of fun with it and think you will too! www.biorxiv.org/content/10.6...

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

Overly proud that Katie Holden's image won Evident Microscopy's 6th Annual Image of the Year "Global Winner" award🏆 The image shows Live iPSC-derived neurospheres. DNA (magenta) & MT (blue) were stained with our probes SiR-tubulin & SPY555-DNA probes. evidentscientific.com/en/landing/i...

The RasgonLab is anticipating several postdoc openings to work on development & application of CRISPR in arthropods, dependent on final approval of funds and HR approval of positions. Candidates must already be physically located in the USA. H1B visa sponsorship is not possible. Email me for info

Mesmerizing light sheet imaging of neutrophils swarming at a yeast target! The neutrophils were labeled with SPY650-DNA (yellow) and a calcium dye (blue). This movie is part of the recent manuscript by @strickland-evelyn.bsky.social that we highly recommend reading! www.biorxiv.org/content/10.6...

Happy #fluorescencefriday (and start of vacation!) to all those who are celebrating Lifeact-labeled epidermal stem cells closing a wound after in vivo adult zebrafish skin injury

Zebrafish finds Nemo. New paper with our great collaborators on gap junctional communication in widely divergent species. www.nature.com/articles/s41...

It's out! Happy to present ITEC, a semi supervised algorithm with an extremely low error rate that can track cells in files of any size (think Terabytes!). We used it in many organisms, including zebrafish, to study how organs form and linked it to gene expression www.biorxiv.org/content/10.6... +🧪

Happy #FluorescenceFriday! I've shared this before but am reposting b/c I think the developing #lung is just so darn pretty! This is an E18.5 🐭 lung with 🟢 marking cells that express my favorite gene, Shh.🟣 marks cell membranes. 🔬 by @stjuderesearch.bsky.social postdoc👩‍🔬 @christinaadaly.bsky.social 🧪

This movie shows lysosomes (orange) and keratin (gray) in a cultured cell over 10 minutes.

I am proud to have contributed to this project during the first part of my postbaccalaureate fellowship, and excited to spend the rest of my time in this lab further investigating this structure.

#KnowYourZDM: In 2019, a 10-year-old patient w/ a life-threatening lymphatic disorder was losing hope. Zebrafish to the rescue! Scientists created zebrafish with the same gene mutation and found a melanoma drug that fixed the fish. Then, doctors used the same drug on the patient to save his life! 🧪

#KnowYourZDM: Humans and #zebrafish carrying mutations in VEGFC or its receptor (FLT4) have defects in the formation of their lymphatic systems, which are important for draining lymph back into the circulation system.  As a result, these individuals display severe #lymphedema. 🧪
