SAVE THE DATE for the 13th Canadian Developmental Biology Conference — March 7–10, 2027 — bringing together researchers, trainees, and innovators in developmental biology from across Canada and beyond.

It's out! Happy to present ITEC, a semi supervised algorithm with an extremely low error rate that can track cells in files of any size (think Terabytes!). We used it in many organisms, including zebrafish, to study how organs form and linked it to gene expression www.biorxiv.org/content/10.6... +🧪

We‘re looking for a motivated Master student to join our team! Do you want to optogenetically control metabolic activity to see how metabolism affects patterning and morphogenesis? 💡🧫🧬🔬 Then please apply! #optogenetics #metabolism #devbio #hESCs Please RT. Thank you!🙏

I am thrilled to share our paper introducing RBPscan, a novel approach to profile RNA–protein interactions in living cells. Free access link at the end ⬇️ 🧵 1/ www.cell.com/molecular-ce...

#Canada 🍁 has opened prestigious CIRTA fellowship for internationally based candidates in Ph.D. and postdoctoral levels. We (Physical biology of developing systems lab at McMaster University) are interested in recruiting through that stream. Please apply / spread the word for those interested:

Oh my god, @biologyopen.bsky.social put this newbie next to John Gurdon in their @biologists.bsky.social 100-year anniversary cover dedicated to reviewers! What a lovely gift and coincidence for closing the year... 🤩

Lovely little pre-Christmas present to see this out @natcellbio.nature.com! Some 🔥 new results in here since the biorvix incl (1) a new RARE-GFP reporter ✳️🙌, (2) additional NMP quantification 🔢, (3) no neural tube patterning on RA inhibition 🙅 etc. Enjoy! 😍 www.nature.com/articles/s41...

It was one-of-a-kind moment to meet Sir John Gurdon at @socdevbio.bsky.social meeting in 2019. Such a humble, down-to-earth personality who was deeply content with life! An exemplary scientist that one could find at the benchside playground regardless of age or career stage! May he rest in peace...

1/5 Lab's first manuscript 🎉 is out @biorxivpreprint.bsky.social today! Beautifully, it is performed by a senior undergraduate thesis student, Mohammed! We developed a 3-D printed #zebrafish embryo imaging chamber 🔬and connected it to syringe pumps to be able to perfuse drugs in a timely fashion. 🧪

🚀 Our new paper is out @natmethods.nature.com! Kuffer & Marzilli engineered conditionally stable MS2 & PP7 coat proteins (dMCP & dPCP) that degrade unless bound to RNA, enabling ultra–low-background, single-mRNA imaging in live cells. 🔗 www.nature.com/articles/s41... 🧬 www.addgene.org/John_Ngo/

Mathematical modelling of the first fate decision This Research Highlight showcases the work from Maria Avdeeva, Madeleine Chalifoux, Bradley Joyce, Stanislav Y. Shvartsman, Eszter Posfai @eposfai.bsky.social : journals.biologists.com/dev/article/...

Preprint - Excited to present WHOLISTIC, which extends the concept of whole-brain functional imaging to the entire body. Pioneering work by incredibly talented Virginia Ruetten @vmsruetten.bsky.social, this platform reveals whole-organism cellular dynamics in vivo. www.biorxiv.org/content/10.1...

Are different cell types like oil and water? Over a century ago, researchers found that dissociated sponges and embryonic tissues can self-assemble into functional structures. Join me, @benswedlund.bsky.social to explore the differential adhesion hypothesis & its applications in tissue engineering!

CIHR rant here: our panel funded 6 (!!) out of 42 applications. That is only 14% success rate. That is as bad as the worst of times. So much good science left unfunded, labs closing, skilled workers let go. Without a $$ infusion, the Canadian research ecosystem is never going to survive and thrive.

I was interviewed recently by @stemcellpodcast.com I witter on about morphogens, notochord, @dev-journal.bsky.social & how biology is becoming a data science Thanks @stemcellpodcast.com for talking to me stemcellpodcast.com/ep-299-spina...

📣 We're on the lookout for a creative postdoc with strong computational skills! Be the go-to person in the lab for building simple but powerful simulations that test wild ideas on biological rythems: from daily cycles of mussel groups at deep sea, to firefly flash synchronization! More info below👇

Have you ever thought about inflating tissues? Or maybe quickly deflating those inflated tissues? New #EpithelialMechanics pre-print: doi.org/10.1101/2025... 🧵 with pressure control, multiscale buckling, controlled wrinkling

Happy to share a new preprint from my lab! We characterize the on/off kinetics, light dosage-dependence, and more for a suite of optogenetic signaling activators in zebrafish embryos 💡 www.biorxiv.org/content/10.1...

Lastly : if Canada wants to be serious about this, they should massively increase tri council grants for everyone, to create those self reinforcing effects. Everything is explained in the Bouchard report ised-isde.canada.ca/site/panel-f...

It has been a while since I advertised some of the tools we have released to help researchers analyze the zebrafish genome. So a brief Bluetorial on our zebrafish genomics UCSC public data hub and the bigger effort led by @ferencmueller.bsky.social to create a zebrafish ENCODE project (Danio-CODE):

Tenure-track Faculty position just opened up in my department! If you want to be part of a dynamic group who is excited about science, apply. For more details, visit www.usherbrooke.ca/emplois/offr... Please share in your networks! #microsky

Beautiful #microscopy and science! Quite interesting that Wnt signal's role appears flipped in between cnidaria and bilateria... 🧪
