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

Happy holidays from the Elkouby lab ✨

Manuscript accepted old fashioned Manhattan🤟🏼 Happy holidays! ✨

1/3 I am very excited to tell you about our latest work where we looked not only into sea anemones but also 🪸 We find in #Nematostella that stress induces not immunity, but also viral replication, actually much faster than the immune response! 🧵 www.biorxiv.org/content/10.1...

www.nature.com/articles/s41... (1/n) Ever wonder how transcription factors locate, "invade," and activate their enhancers during cell fate acquisition? 🧬🚀 Check out our latest collaborative work with the Soufi lab, now published in @Nature

An intriguing mechanism of germline cyst formation through innovative live imaging in fetal mice gonads, and computational modeling. Check out my dispatch in @currentbiology.bsky.social on this beautiful work. kwnsfk27.r.eu-west-1.awstrack.me/L0/https:%2F%2…

Elkouby lab presentations at @ASCBiology @EMBO #CellBio2024 👇👇👇

Finally getting to this masterpiece by @amartinezarias.bsky.social On my way to @ascbiology.bsky.social #CellBio2024, @EMBO , seems appropriate.

🔊 We are recruiting PhD students and Postdocs! We are seeking highly motivated, talented, and creative researchers, with strong background in cell and developmental biology, who are looking to spearhead original interdisciplinary investigations, addressing overlooked biology. 1/5

After so long, I’m finally back in the action 🤟🏼 (Best way to refuel writing, and a good anger management plan for everything going on all around)

🔊I am new on this platform. New updates will be posted here, but as an introduction to our research focus and contributions thus far, feel free to visit my twitter/X profile 👇🏼 I promise, (almost..) only science content. x.com/yanivelkouby

First on this platform - manuscript accepted Negroni 🤟🏼
