Physical Biology of Developing Systems

Really cool experiments to solve a developmental mystery! 👏🏻I see how torque arises, but where does the chirality come from? Why are they whirling counter clockwise as seen from dorsal? Sorry didn't dig the preprint yet..

If you can combine with a controlled (in space and/or time) chemokine signal, would be interesting to see how to win the tug of war with optogenetic pulses...

I was seeing those in clouds frequently when doing drug induced somite experiments 🙃

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.

The day which will come for every single one of us... It is interestingly different to live expecting it to come near while enjoying the legacy of what has been gifted and what awaits around the corner. With much respect and support. 🩵

Ep. 299: "Spinal Cord Development" Featuring Dr. James Briscoe - The Stem Cell Podcast Dr. James Briscoe is a Group Leader at the Francis Crick Institute and Editor-In-Chief of Development. His lab uses an interdisciplinary approach, including mice, chicks, and other models, to study de...

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

To see supplementary figure S39 which I have no idea how ended up there go to page 109!

📣 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!

Have you ever thought about inflating tissues?
Or maybe quickly deflating those inflated tissues?

Congrats to Cyril on this very cool first, first author publication 🏆! This started when he was a bachelor's student (and he's now completing his masters!).

And many thanks to my other awesome co-authors🙏

Dynamic BMP signaling regulates sclerotome induction and lineage diversification in zebrafish Summary: Loss- and gain-of-function manipulations reveal that dynamic regulation of BMP signaling is essential for the induction and diversification of the sclerotome lineage in zebrafish.

Excited to share our latest work led by my PhD student Linjun Xie on sclerotome development: Dynamic BMP signaling regulates sclerotome induction and lineage diversification in zebrafish, now published on @dev-journal.bsky.social! #zebrafish #devbio 1/8 doi.org/10.1242/dev....

It’s out! 🥳

Stas Shvartsman from Princeton University explains how the coupled oscillators are interesting for Physicists from Huygens apparatus in 1600s to fruit fly embryo cell divisions.

Paul François from UdeM shows BSC audience dynamic features of waddington landscape for segmentation clock in embryos.

Ahmad Mahmood from McGill Univ explains how plant pollen tubes are tweaking the physical limits to grow so quickly.
