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/

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

Paper alert! I am really pleased to share the final version of the work led by Irène Amblard in the team on a regulatory switch controlling Cdx2 expression during posterior body development! #regulatorylogic #devbio @mrc-lms.bsky.social @imperialmed.bsky.social

Very very happy to participate in the 10th Biophysical Society of Canada annual meeting ! Opening words by Cecile Fradin/ Très heureux de participer au 10e congrès de la BSC avec le Discours Introductif de Cecile Fradin. #BSC2025

Great #zebrafish talk on tissue biomechanics going on at the @biophyscanada.bsky.social meeting @mcmasteruniversity.bsky.social given by @manningresearch.bsky.social #bsc2025

Lovely microscopy with too many -but never enough- somites in them! 🤩

Looking for MSc and PhD students to join my lab and work on vascular development in zebrafish and mouse. Feel free to share or reach out if you have questions! jobrxiv.org/job/universi...

I'm excited to join @pritiagarwal.bsky.social and @tarafinegan.bsky.social as a co-organizer for the International Developmental Mechanics Seminar Series. The series will resume in September 2025, and call for speakers is now open! More info is on our new website: sites.google.com/view/devmech...

Fluorescence lab is upon us. Time to get to know (and love) beads. #AQLM2025

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... 🧪

1/2 We are hosting the Biophysical Society of #Canada annual meeting @mcmasteruniversity.bsky.social in May 20-23rd. This is a single stream event with sessions on #computational &theoretical #biophysics, new tools for biophysics, #development, mechanics of cells &tissues, #AI in biophysics,...🧪+

The language used by lecturer here is worrisome as well. A mistake in import documents is not stg. to be dumped on the postdocs. Rather, the lab should pay some effort to reach out to the officials to undertake the responsibility. Esp. when hired a researcher politically targeted in their country.

We are hiring! A postdoc position is available in the lab studying gene expression dynamics in Drosophila embryos, as part of a larger research effort in collaboration with @mrattray.bsky.social 🧬🔬🪰 Full details are in the ad: www.jobs.manchester.ac.uk/Job/JobDetai...

⭐️ Please Fwd. Are you in Paris on 16th May? See👇 poster of symposium on « Information processing in biological systems » @collegedefrance.bsky.social Fantastic line of speakers 🤩. It is free, w/o registration, and it will be exciting.m! Follows from my series of lectures at CdF last fall.

Scientists in the Ozbudak Lab discovered that DeltaD — once thought secondary to DeltaC — also regulates Notch signaling, playing a key role in synchronizing the segmentation clock through a newly identified feedback loop. rdcu.be/ec2Yz

I’m excited to participate in the Women in Biophysics event organized by Divya Yadav, Lauren Conger and Jie Xiao. I look forward to sharing my perspectives and hearing those of inspiring colleagues.
