If you are using CRISPR in zebrafish, you are most likely using the Cas9 plasmid from Wenbiao Chen, one of the most impactful contributions to the community. Consider voting for Wenbiao for the BOD position.

📣 Hiring a postdoc! My lab is hiring a postdoc to model rare genetic diseases in zebrafish utilizing CRISPR, high-throughput phenotyping, and multi-omics approaches.

Special shoutout to Wei Qin from @varshneylab.bsky.social lab. He has done the hard work to make precise editing in zebrafish a snap! Also shout out to all the other speakers in the series!

Cleaning freezers before I move to a new place. Found these plates from @burgesslab.bsky.social, these plates made my career, hard to throw them now.

Is Ensembl dead? Never worked for me for the last few months.

A powerful new technology developed at OMRF could dramatically speed up the process of diagnosing rare genetic diseases. Read more: omrf.org/2026/02/03/o...

High-efficiency TadA cytosine base editors for precise modelling of human disease variants

Our paper on TCBE-Umax is out in @natbiomedeng.nature.com! We developed these high-efficiency cytosine base editors for zebrafish, enabling rapid functional testing of disease variants. This work is led by a talented scientist, Wei Qin. www.nature.com/articles/s41...

Folks, it is finally out! Our paper on T2T assemblies of the zebrafish genome is on BioRxiv: www.biorxiv.org/content/10.1...

Published October 25 years ago, “Effective targeted gene ‘knockdown’ in zebrafish” by Nasevicius & Ekker detail use of antisense morpholino-modified oligonucelotides or #morpholinos that inhibit translation. This landmark spurred a revolution in targeted gene knockdown in vivo. #ZebrafishFunFacts 🧪

While I'm sad our cover submission wasn't selected for our recent human duplication paper, check out the super cool illustration created with @lazaroillustration.bsky.social ! Certainly, you will be seeing Dennis lab members running around with "fishman" t-shirts at future meetings, inspired by Ohno

Does anyone have #zebrafish LC3 reporter lines and would be willing to share them with us? #askzebrafish

#zebrafish genome update, our T2T assembly of the inbred strain of AB (M-AB) generated by my buddy Nori Sakai has now been released at NCBI and will be a second reference genome for zebrafish (GRCz12ab):

CRISPR technologies have transformed genetic research since their adaptation for genome editing in 2012. @burgesslab.bsky.social and I summarize key functional genomics tools being used in vertebrate models. www.nature.com/articles/s12...

Congratulations, Megan! As always inspiring work.

Our paper on TadA-based cytosine base editors is now online in Advanced Science. We introduce zTadCBEs—a next-generation CRISPR base editor optimized for zebrafish. advanced.onlinelibrary.wiley.com/doi/10.1002/...

Congratulations!

🚨🚨🚨 Tol2kit announcement! We have rebuilt the wiki that was corrupted a few months ago! We’re in the process of also linking it to the original address. Please visit us here: tol2kitkwan.genetics.utah.edu Thank you for your patience!! #zebrafish #transgenesis #plasmids #sharing

Dear #izfc2025 participants, if anyone of you are interested in how transcription control defines mRNA fate and translation in zebrafish development, there are/will be several PhD and postdoctoral positions (funded by the Wellcome Trust) for this research. Please find me if interested.

The winners of the 2025 George Streisinger Award are the Course Directors of the Zebrafish Development and Genetics course at MBL, for their tremendous contributions to our amazing community for >25 years! #izfc2025

The new impact factors are out: Development – 3.6, Developmental Cell – 8.7. Why the steady decline in two of Dev Bio's flagship journals?

New preprint just dropped! I really love this paper for many reasons, but the biggest is that this is a really old school genetics/devbio paper, traditional genetics approaches still have the JUCHE. Several years ago now visiting professor Chunxin Fan participated in an ongoing screen for

It has been a while since I advertised some of the tools we have released to help researchers analyze the zebrafish genome. So a brief Bluetorial on our zebrafish genomics UCSC public data hub and the bigger effort led by @ferencmueller.bsky.social to create a zebrafish ENCODE project (Danio-CODE):

Our Collaborative work on TRMT1, a tRNA-modifying enzyme, is out in @ajhgnews.bsky.social. A team of human geneticists led by Drs. Houlden' @qs-neurogenetics.bsky.social and Dragony Fu' labs identified 43 individuals from 31 families with biallelic TRMT1 variants. www.cell.com/ajhg/fulltex...

Piece by @stephaniemlee.bsky.social on one way we are trying to band together to get information about what the hell is going on. Kudos to @annikabarber.bsky.social interviewed here www.chronicle.com/article/nih-...

We pay our academic editors (we don't do special issues with guest editors). Beginning in April, we also pay peer reviewers @biologyopen.bsky.social details to be announced at #biologists100 bit.ly/4h1cmCC @biologists.bsky.social

A journal contacted me to serve as guest editor; I sent them my hourly rates. They came back saying, please suggest someone else who is willing to volunteer. 😆

Reminder that NIH grants are NOT reckless spending. They are extremely competitive. The mean success rate of all grants is <24%. Far lower for R01's that are the lifeblood of most academic labs. All the data can be found here: report.nih.gov/funding/nih-...

Wondering if your study section cancelled? I update this sheet daily. As of today, 56/124 study sections that should have met since Jan 2, 2025 have "not met as scheduled." docs.google.com/spreadsheets...

Kickass worm-friend @rnareylab.bsky.social wrote a piece for @sciencehomecoming.bsky.social and you should read it and send it to your red-state friends and fam. Hurting research hurts all of us. #invertsolidarity 🧪 www.heraldbanner.com/opinion/colu...

An update on NIH funding and the loophole that's keeping it out of scientists' reach. H/T to @avaskham.bsky.social, who had it first. #HigherEd #AcademicSky www.chronicle.com/article/desp...

It’s @katherinejwu.com with the receipts. The NIH memo undercutting the NIH came directly from Trump officials. www.theatlantic.com/health/archi...

MNG study section scheduled in person for 2/20-2/21. Put together in Dec, assignments out 1/14, travel arrangements made mid-Jan. Was NOT posted to Fed Reg. Critiques due 2/14. All normal to that point. Moved to zoom 2/18 in am, discussion order posted 2/18 pm. CANCELLED just now.

I just found out that the study section for my grant has been canceled one day before its scheduled meeting.

AJHG @ajhgnews.bsky.social has a weird policy of allowing only two authors to be listed as senior authors; HGG Advances goes even further, allowing only one person to be listed as a corresponding author. It only hurts the junior investigator.

🆘 Email from my colleague on the Hopkins Research Council🆘 Can anyone confirm? 🧪

Disruptions to the NIH impact more than just science; they will hit all Americans in our wallets. I spoke yesterday with Becky Fogel from @kutnews.bsky.social about the important role NIH-funded research plays in the economy. 🧵 1/n www.kut.org/education/20...

“zTadCBE variants thus offer a robust set of [cytosine base editors] for precise and efficient C-to-T editing in zebrafish, promising to advance the rapid functional assessment of genetic variants in vivo.” New work from @varshneylab.social et al. 🧬🐟

Can we fast forward to 2026? I am done with 2025.
