One more week to apply!

We are back at it again: the next @v4sdb.bsky.social Student Summer School (on Spatial Transcriptomics) with support from @biologists.bsky.social and contrinbutions from Enikő Lázár, @yinanwan.bsky.social, Jonathan Enriques and khodosevichlab.bsky.social. Encourage your students to apply!

It is hard to foresee what’s in store for Hungarian science in the next years, but I think @barabasi.bsky.social's editorial in Science highlights the best of what we (can) hope for: not just restoring what was lost, but rebuilding something better. www.science.org/doi/10.1126/...

Happy 100th Birthday to David Attenborough! Thank you for a lifetime of inspirational broadcasting, and all your work to promote the understanding of evolution and the natural world.

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

🧬 Celebrating DNA Day (25 April)! DNA research has completely reshaped how we understand evolution. By decoding genetic information, scientists can trace connections between species, uncover shared ancestry, and reveal how life adapts and diversifies over time 🧪 #EvoKE #DNAday

Project Hail Mary is a beautiful brilliant film. But molecular biologists be warned there's a deeply disturbing scene midway through when Ryan Gosling's scientist places two eppendorfs directly next to each other in an otherwise empty unbalanced microcentrifuge & sets it spinning with wild abandon.

Our condelences to those that knew him 😞 #zebrafish Read about Prof. Weinberg’s life and career in his obituary: www.bio.upenn.edu/news/2026/03...

I’m extremely saddened to learn that my former PhD mentor, Eric Weinberg passed away past week. The guidance and opportunities he provided in his lab hooked me on fish research for life. This last picture of us was taken 4 years ago, when we met for a lunch in NYC. RIP Eric.

For last week’s Brain Awareness Week activities, my fantastic students designed a deck of “pokémon” cards with actions related to the lab’s work. Even more fabulously they designed one card for me.

#AnimalResearch : myths vs. facts? The new @eara.eu site cuts through the noise. 🔍 Just launched: A fresh, user-directed hub for real talk on animal research — with actual lab images, policy breakdowns, and news you can trust. Science thrives on openness and accessibility. Check it out:

Just discovered the wonderful covers of 'Genes to Cells', the journal of the Molecular Biology Society of Japan @mbsj-official.bsky.social – absolutely beautiful! here some examples inspired by mitosis, CRISPR, the DNA helix, and plant pigments

Time for a thread on our Christmas preprint “Origin and evolution of acrocentric chromosomes in human and great apes”. I had so much fun with this project and paper. It will be hard to summarize in a thread, but I’ll try www.biorxiv.org/content/10.6... [1/21]

📅EZM2026-Save the date! We are delighted to welcome you to the 13th European Zebrafish Meeting in Vienna, Austria! 📑Submit your abstract by March 15 2026! ✅Early bird registrations are now open until April 15th 2026 We are looking forward to seeing you there!

We usually credit Charles W. Creaser with the first scientific zebrafish paper, but that is true only with some caveats. Meet another strong contender, Hubert B. Goodrich, interested in all things related to fish genetics. (Photo: Smithsonian, prod.learninglab.si.edu/resources/vi...) (1/9)

Next, in my miniseries on early researchers using zebrafish is Jane M. Oppenheimer, fish embryologist and science historian par excellence. (True, I’m cheating here a bit, but if I mentioned Hellen Battle in the previous bluetorial, it is fair to mention Oppenheimer here.) (1/4)

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. :)
