Second in the “unsung heroes of zebrafish research” series is Canadian born Kenichi Kenneth Hisaoka. We might consider him the “grandfather” of zebrafish toxicology, and also the author of the best pre-Kimmel “developmental series” table. (1/8)

Over the past weeks I have been reading the earliest papers on zebrafish development, and came to realize that in the “canonized" version of zebrafish history we neglect some important people pre-Streisinger. I will try to correct here the record. Let’s start with Edward C. Roosen-Runge. (1/7)

30 years ago today, December 31st 1995, the last ever Calvin & Hobbes comic strip was published. Even now, I still find it so poignant & moving.

I was today years old when I learned that there is a superb (freely available) documentary from 1961 on early zebrafish development by J.V. Durden. collection.nfb.ca/film/embryon... (1/2)

It was great to host Kevin @wiringthebrain.bsky.social for two fantastic lectures. There was a lot to think and talk about :). Thanks for coming!

Free Will in an Indeterministic Universe - my lecture at the Hungarian Academy of Sciences, Dec 2nd 2025 www.youtube.com/watch?v=t61N... w/ thanks to @mvargam.bsky.social for the invitation! 😊

Gentle reminder that everyone should read Jacob and Monod, 1961. And then read it again every once in awhile. A master-class on clear writing (and, ya know, Nobel Prize winning stuff, too). www.sciencedirect.com/science/arti...

I’m very much excited about these ones, and the discussions they will bring. :)

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

#ZebrafishFunFacts: In a 2016 article titled, "The Doctor of Delayed Publications - The remarkable life of George Streisinger", @mvargam.bsky.social takes the reader down memory lane to provide a life history of the Founding Father of #zebrafish research. 🔗 thenode.biologists.com/doctor-delay... 🧪

It is a fantastically well written plea to fund basic sciences. Money quote: "We are currently burning through a stockpile of knowledge accumulated during a more enlightened era of public investment, while allocating insufficient resources for replenishing it."

The figures from this book are all freely available through @figshare.com, hopefully helpful for presentations and teaching: figshare.com/projects/Epi... Please let me know if you find any inaccuracies and I'll fix them. I've already updated one of the figures. #EpigeneticsBook

Very sad news, John Gurdon has died. A developmental biologist's developmental biologist, Nobel prize winner His work is the foundation of much of today's dev & stem cell bio. An inspiration to many, including me. Always asking questions & wanting the answers www.magd.cam.ac.uk/news/profess...

Sad news: Jane Goodall has died. She did more than any other human for our understanding and appreciation of our closest relatives, the chimpanzees. That chimpanzees are Endangered tells you everything about our species and about what made her so exceptional. www.nytimes.com/2025/10/01/o...

Massive sibling regression study finds that human traits are largely environmentally driven (average heritability = 0.3)

With the caveat productivity is defined as the number of papers published, it's notable to see that the gender and English proficiency gaps are about the same overall. Then the gender gap decreases along the career, while the English proficiency gap widens

A giant in molecular biology and virology has passed. RIP David Baltimore. www.nytimes.com/2025/09/07/s...

Wow, that was amazing! We thank everyone for attending the V4SDB 2025 meeting! You all made it an excellent conference, where we had the opportunity to hear from outstanding speakers,share ideas and experiences, and of course have some unforgettable time during social activities!

Next we look forward to hearing from Máté Varga @mvargam.bsky.social from ELTE Eötvös Loránd University, who will tell us about the Evolution and Development of Breathing Strategies in Paradise Fish! #V4SDB2025 #developmentalbiology #evodevo

Just realized that I have not moved over the lab’s yearly hike thread to Bluesky yet :-/. So previously (somewhere on X) we had summit photos for: Triglav 🇸🇮 (2864 m) in 2019, Säuleck 🇦🇹 (3086 m) in 2021, Kôprovský štít 🇸🇰 (2367 m) in 2022, Ankogel 🇦🇹 (3254 m) in 2023 and Mangart 🇸🇮 (2679) last year.

Some of our colleagues arrived yesterday to attend the amazing two-day Young Developmental Biologist Workshop, a Round table on the use of Artificial Intelligence in research, and of course some social networking! #V4SDB2025 #conference #developmentalbiology #evodevo #morphogenesis #organoids

Better later than never, I guess - we are quite happy to see this paper out in @commsbio.nature.com. Spearheaded by my super talented colleague, Zoltán Varga, we have compared the behaviour of zebrafish and paradise fish larvae, which turned out to be quite different. www.nature.com/articles/s42...

Plus, the “Barkley Marathon” included a canoe trip to the other side of the river, and, of course, to become a #Finisher (we had 5), you needed to bring the pages back FIVE times. But everyone knows that, right? It’s #Barkley! 😉

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...

I wrote a little bit about a cool recent paper looking at heritability estimates from very large registry data, and how we still really don't understand why outcomes track in families. A short 🧵:

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 "reproducibility crisis" in science constantly makes headlines. Repro efforts are often limited. What if you could assess reproducibility of an entire field? That's what @brunolemaitre.bsky.social et al. have done. Fly immunity is highly replicable & offers lessons for #metascience A 🧵 1/n

some how replicating this post seems very appropriate. Sad to see you go Dr. Stahl
