I am starting my lab at the University of Geneva next January! Incredibly excited to soon be joining the MOCEL department as an Asst. Professor. The lab will use evolutionary cell biology to study chromosomes, centromeres & speciation 🧬🔬🌱 Intrigued, want to join or collaborate? 🔗 helsenlab.org

🎨 job alert 🐠 Come join us! We have two positions open! These are part of our @erc.europa.eu funded project on the mechanisms underpinning convergence of colour patterns in cichlid fishes! Closing date: 16th August. Postdoc: www.cam.ac.uk/jobs/researc... Technician: www.cam.ac.uk/jobs/researc...

Took me a while, but we finally have a new lab website: ydagdas-lab.github.io/Lab-Website/ I will do my best to keep this one up to date.

🪲🪰 Our preprint is out! This was a team effort with @wolframponisch.bsky.social, @matthewabenton.bsky.social and Ewa Paluch. We asked whether Drosophila and Tribolium use the same cell behaviours to fold their embryos during gastrulation. 🧵👇 www.biorxiv.org/content/10.6...

Huge thanks to Iñaki Ruiz-Trillo for opening our Developmental Biology series 26/27 @embl.org. Iñaki showed us how studying our closest unicellular relatives is reshaping what we know about animal origins and why exploring the unknown is key to any field. We couldn't have asked for a better start! 🦠

How mammals get their fur? New research from the Milinkovitch-Tzika lab, published in PNAS, shows that chemotaxis—cells moving toward chemical cues—drives hair follicle precursor self-organization during embryonic development, generating diverse fur patterns across mammals. doi.org/10.1073/pnas...

#2 Close collaboration with @rocha-lab.bsky.social across institutes. @catfigueiredo.bsky.social shows that neurogenic progenitors in the developing retina can respond to cell death with an unexpected self-renewing division. I am sure Mauricio has more to say :-). www.biorxiv.org/content/10.6...

We are trying for a hattrick this month and two out of three are out: #1 Great work by Margarida Cruz et al. showing that tissue context in addition to cell intrinsic programs can determine migration mode of neurons. Retinal Bipolar Cells as an example. Check it out! www.biorxiv.org/content/10.6...

What if an embryo made immune cells before it finished building the tissue they usually come from? In our new preprint, we show that annual killifish embryos specify neutrophils before germ layers are fully resolved. www.biorxiv.org/content/10.6... Huge thanks to my PI, @ohnolog.bsky.social ! 🧵

Super excited that the first preprint from the lab is out! Led by an amazing student, Gaurav @gvaidya.bsky.social, jointly supervised with @mwdorr.bsky.social.

The first preprint from my PhD is out! :thread: How does an animal choose between two completely different reproductive fates? Here’s how one planarian does it :point_down: www.biorxiv.org/content/10.6...

I am thrilled to share my PhD work with @nicolettapetridou.bsky.social @embl.org: www.biorxiv.org/cgi/content/... A fun collaboration with Bernat Corominas-Murtra, Adrián Aguirre-Tamaral, @bart-smeets.bsky.social , Jef Vanghel and Tom Belpaire! Read the story in the comments below ⤵️

Double preprint! 👇 Check out our latest studies on timing, heterogeneity and collective behaviour (with a fun tiny bonus on evolution!) 1. www.biorxiv.org/content/10.6... 2. arxiv.org/abs/2605.13234

If you’ve built DNA-barcoded antibody panels, you know the pain: every barcode means another conjugation. In our new preprint we introduce UnO, which transforms antibody conjugation problem into a universal barcode conversion workflow, enabling rapid panel generation. www.biorxiv.org/content/10.6...

Do you work with scRNAseq data in non-model organisms that have less-than-stellar gene annotations? ✨ 🧬 You might be interested in GeneExt, a nifty little tool by @zolotarg.bsky.social in @arnausebe.bsky.social's lab, published in #Bioinformatics earlier this year. #singlecell #transcriptomics

Excited to share our new preprint! 🧬❄️ by brilliant @mdreimann.bsky.social and great collaborators! Using cryo-ET&EM, we reveal archaeal chromatin in a near-native state: variable-beads-on-a-string fibers shaped by growth phase and histone composition #ArchaeaSky www.biorxiv.org/content/10.6...

Amazing work! Huge congratulations to @bournsupremacy.bsky.social, @mwdorr.bsky.social , and all co-authors 🙌👏🙌

Vaccines are humanity's greatest scientific achievement.

A very pleasant surprise to see that we got the cover for this paper 🥳 @natphys.nature.com

Here the published version of our work on uncoupling different types of tissue phase transitions during development! Find out more on how contact surface tension-driven rigidity transitions trigger tricellular junction formation and initiate epithelial organization! @natphys.nature.com

🏳️‍🌈This June, we celebrate Pride by discussing with @gunawanlab.bsky.social about his personal and academic journey as an LGBTQIA+ immigrant. Happy Pride month! #PrideinSTEM #LGBT 👉https://rdcu.be/forCt www.nature.com/articles/s41...

Thrilled to be joining the ZMBH, where my lab will continue to explore the evolution and engineering of living membranes. Farewell @bcube-tud.bsky.social...I couldn't imagine a better place to have started my lab! I'm perpetually grateful to my lab group for making this such a successful adventure!!

Two great scientists and humans, whose collaboration shows what it’s like to do science as a positive-sum game. Wonderful news for evolutionary cell biology and for you two @dudinlab.bsky.social @gautamdey.bsky.social! 👏

Congratulations, Gautam Dey and Omaya Dudin! The two collaborators have received the 2026 EMBO Gold Medal for outstanding contributions to the field of evolutionary cell biology. www.embl.org/news/awards-... @gautamdey.bsky.social @dudinlab.bsky.social @embo.org

Science really takes a village. Thrilled to share this with my friend @dudinlab.bsky.social, and with our brilliant and fearless teams, our collaborators around the world and our mentors - in my case a special shoutout to Buzz Baum, Jan Ellenberg and @monicabettencourt.bsky.social. 1/2

"Humbled to receive this recognition. This belongs as much to my team, my family, & to my home, Palestine: the people, the place, the joyful stubbornness to enjoy life." Cheers buddy @gautamdey.bsky.social Thx to my mentors @sophiemartinlab.bsky.social, @paveltomancak.bsky.social, & Pierre Gönczy.

🚨 New preprint 🚨 Massive shoutout to first author @abinagui.bsky.social !!! The common view is that regenerative competence declines with age. We challenge this idea by showing that axolotl tail regenerative competence is emerges during a defined embryonic window. www.biorxiv.org/content/10.6...

Reminder I will be in Paris and that, if you are, too, I'd love to see you there and chat and maybe plot a bit 👀🧪

This is a video of a ribbon eel (Rhinomuraena quaesita) captured by Tjeerd Schone in waters near Padangbai, Bali in 2025. Every ribbon eel is born male, with jet black skin & transitions first to this colorful male, then to female - only when they've reached their max size. Let's talk about it.

How do sperm and egg fuse? Surprisingly, we still don’t fully know… Our field has uncovered many pieces of the fertilization puzzle, but not how they fit together. We identify ✨ SPARK ✨ - a conserved sperm complex that couples sperm-egg binding to fusion. tinyurl.com/34cm4xat Read on! 🧵👇

Multinucleate cells challenge deeply-held assumptions about complexity, ecological success and evolution. Postdoc extraordinaire and gifted writer @mrosjac.bsky.social tackles this subject with aplomb - tell us what you think! www.sciencedirect.com/science/arti... @currentbiology.bsky.social
