Spontaneous synchronization in the lab today, induced by our #zebrafish?

#zebrafish advice: We are looking for a protocol for antigen retrieval for zebrafish embryos/tissue whole mounts. Any pointers would be appreciated 🙏🏼

🥁We are recruiting PhD students/Postdocs with strong proven background in developmental/molecular/cell biology & related areas, for various projects- check out our lab website👇🏼 We offer: competitive stipends, super equipped lab, fun international team! yanivelkoubylab.com

Thank you for featuring this beautiful image of a #zebrafish developing ovary from Amal’s recent work! 🐟🔬✨

I had great fun presenting and having really interesting discussions in this really nice forum. Thanks for the invitation!

Now out from our lab in @currentbiology.bsky.social! An mTOR-Stat3-Stathmin pathway controls #centrosome and #microtubule dynamics for #oocyte polarization www.cell.com/current-biol...

SAVE THE DATE! Stoked to organize the 2026 Santa Cruz Developmental Biology Meeting with @rashmi-priya.bsky.social, @lowelab.bsky.social, and Shelbi Russell. Come learn about Biomedicine, Biomechanics, and the Biosphere, August 24-28, 2026. Registration dates, etc., coming soon! Please RT

Was a pleasure to participate in ScoRe - Scientific Conference On REproduction - celebrating 150/y since the observation of sperm and egg pronuclear fusion in @flatironinstitute.org. A stellar gathering discussing all things germ cells! Thanks @haysconun.bsky.social, Stas Shvartsman for the invite!

🔥A second preprint from our lab this week! Especially proud of this one that helps unlock a black box in #reproduction. We propose a #morphogenetic framework for #oocyte production from germline stem cells in #zebrafish and from progenitors in humans. > www.researchsquare.com/article/rs-7...

🔊New preprint from our lab! Zygotene cilia regulates meiosis, germ cell development, and fertility in zebrafish, mice, and humans www.researchsquare.com/article/rs-7...

Super proud of Neta Hart for being awarded the travel grant by The Science Bank and for delivering an excellent talk at the Notch Signaling Meeting about her pioneering work on newly identified mode of early #oogenesis in #zebrafish and human, regulated by Notch (more to come!).

For the new Jewish year, we wish for a better and peaceful year all around, filled with joy, prosperity, and lots of scientific discoveries 🙏🏼

Six more years—plus a lot of blood, sweat, and tears—later, we are thrilled to finally share it: a cytological framework of female meiosis in Arabidopsis! www.biorxiv.org/content/10.1...

I can now share that during the recent Israel-Iran conflict, our main #zebrafish husbandry facility collapsed abruptly, resulting in the loss of ~85% of our fish. With careful management, we were able to preserve all lines, and are currently operating from backup systems. >>

Two Elkouby lab students received the Hebrew University @hebrewuniversity.bsky.social Faculty of Medicine Prizes for Outstanding MSc Thesis today. Congratulations Amal Shawahny and Adam Ahmad for this well deserved recognition, we are super proud of you! 🎉🐟

Grateful to the Israel Science Foundation for additional five years of funding! Thank you to all reviewers and panel members out there for believing in our science. Excited for what’s coming next 🤞🏻

Was a pleasure to give the @embo.org talk in #EMBO #meiosis meeting today, and share our findings about the Zygotene #cilium: novel mechanisms, conserved functions and links to human #reproduction disfunction. Thanks to the organizers for the invite and for a fantastic meeting.

My students @amytlis.bsky.social, Karine Levy, and myself were invited to speak at the Foundation Singer-Polignac #Fertilty meeting, Paris. We could not join in person at the current circumstances. This is how I ended my talk: 🔊

Iranian missiles or on the way… I’m in one bomb shelter, my student Neta is in another, yet we are working on our next paper, shelter-to-shelter. The passion for science and the human spirit will always prevail!

Was a pleasure to serve on the interviewing panel for the @maxperutzlabs.bsky.social PhD scholarship in @viennabiocenter.bsky.social . All finalists were outstanding with excellent and exciting science. Congratulations to the winners!

Super-talented PhD students, Neta Hart and Avishag Mytlis, from our lab rocking the annual meeting of the Israeli #Fertility Association with two talks in one session! Making some splash introducing #zebrafish to the meeting 🐟 @zebrafishrock.bsky.social

Nice collection, well done!

'Centrosomes and cancer: balancing tumor-promoting and inhibitory roles' - It was so much fun writing this review with Renata Basto! Thanks for bringing me on board 🙏 Perfect timing to reflect on the field's most recent advances and open questions 👇 www.cell.com/trends/cell-...

We move to magnificent #meiosis #ChromosomalBouquet & #zygotene cilia with Avishag Mytlis (@yanivelkouby.bsky.social lab, Hebrew University, IL) on unpublished work for countering mechanical forces allowing telomere rotation & clustering. Role in human infertility- #ciliopathies? #UKCilia2025 3/7

Check out our very own @amytlis.bsky.social to learn the latest about the zygotene #cilium in the always inspiring @ukcilianetwork.bsky.social series.

Was a great pleasure to visit @pennmedicine.bsky.social yesterday and give a seminar at my postdoc alma mater @upenn.bsky.social CDB. Thanks @marymullins.bsky.social and @buenoscience.bsky.social for having me!

💥🐟 The new and updated Elkouby lab website is now live! yanivelkoubylab.com

Honored to have given the keynote lecture at the DBSUMI meeting. Such an exciting dev bio community! Thanks @zakswartz.bsky.social for the invitation and kind hospitality at wonderful @mblscience.bsky.social. The naturalist approach to science and rich history in this place are inspiring.

I had a great time visiting Princeton Department of Molecular Biology. Such an honor presenting our work to an audience of giants in the field and meet passionate dev bio trainees. Thanks to the organizers of the Colloquium Series on Developmental Biology for the invitation!

🐟🐟🐟 We are looking for the floxed dnStat3 line (pd59Tg) - Tg(actb2:LOXP-DsRed-STOP-LOXP-dnstat3-GFP), which was generated by the Poss lab (or similar). If anyone maintains the line and able to kindly share embryos, that would be much appreciated. Thanks! @zebrafishrock.bsky.social

Now live! The #DanioDigest for February 2025 is now posted to @the-node.bsky.social 😎 Don't worry, we will still post to Bluesky in a mega-thread in the coming days but until then, get a sneak peek of the latest happenings in the #zebrafish community! #RockOn thenode.biologists.com/daniodigest-... 🧪

bioRxiv had been a huge transformation in science in many ways, and this is yet another step forward. Well done!

Supporting my friends and colleagues in the USA and all over the world in standing for science, for the benefit of all of human kind! 🤟🏼

Birth defects are the #1 cause of death in the first year of life (🧵). Birth defects kill more than twice as many children as cancer. Birth defects are diseases of developmental biology. Here are CDC statistics for 2021. 1/5 wisqars.cdc.gov/pdfs/leading...

ZFIN is now on Bluesky!

Looking forward to this very exciting meeting! Thanks @mhverlhac.bsky.social and @bokelab.bsky.social for organizing and for the invitation.

#Zebrafish friends, anyone aware of specific guidelines for allowed vibration and noise levels in fish husbandry water (in dB, Hz)? I can find reports in papers but not specific guidelines. Thanks! @zebrafishrock.bsky.social

Seeking advice please: Has anyone encountered issues with performing HCR FISH on cultured organs (post culture)? We don’t get a signal in our cultured ovaries, while side by side control of fixed ovaries works perfectly. Thanks! @hcrimaging.bsky.social #zebrafish @zebrafishrock.bsky.social

#TubulinTuesday!!

📣 Latest from our lab, now out in PLoS Genetics @plos.org: The piRNA protein Asz1 is essential for germ cell and gonad development in zebrafish and exhibits differential necessities in distinct types of germ granules. #zebrafish @zebrafishrock.bsky.social > journals.plos.org/plosgenetics...
