Very happy to share our latest work extending iterative immunofluorescence to in toto imaging of early zebrafish embryos (3D-4i), integrated with a 3D-dedicated image analysis pipeline! 🐟🔬📊
Huge kudos to Max Hess for this PhD milestone! 💪

How can we organize current theoretical approaches for developmental biology - from information to dynamical systems & GRNs - into a common framework?

We propose to think along Marr's 3 levels: computational problem, algorithm, implementation

Vertebral skeletal diversity in mammals is remarkable. How do the differences between vertebral size and shape develop and evolve? See how we tackled this question in our paper published in @natcomms.nature.com today!

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

New preprint from the lab! We discovered a transient fluidization in the basal region of human forebrains by tracking microdroplets in cerebral organoids.This “basal fluidization”, absent in gorilla and mouse, may contribute to greater surface expansion in human forebrains

First, check out my recent bioRxiv preprint w/ @oweinerlab.bsky.social: www.biorxiv.org/content/10.1...
We find contractility shifts the proportion of implantation-competent embryos from young and aged females. Keep reading this for more info!
A mechanical origin for implantation defects in embryos from aged females
Women over 35 experience a marked reduction in fertility. The origin of these fertility defects appears to reside in the implantation capacity of the embryo itself, but the mechanistic basis of this i...

Our latest preprint! Into morphogenesis, Yap, ECM, signaling, vertex models, feedbacks/robustness? There is something here for everyone. We discovered a positive feedback loop that extends inner ear canals, and a built-in mechanism that shuts it down when morphogenesis is done. tinyurl.com/464wsjhd

🚨 New paper out in @pnas.org! 🚨

We show that self-generated gradients allow heterogeneous cell mixtures to co-migrate efficiently over long distances —while optimizing their physical interactions!

I am excited to finally share our work on avian left/right symmetry breaking with you. We reveal a tissue-scale active torque dipole generated at the Hensen’s node, thanks to crazy experiments by Julia @juliapfanzelter.bsky.social and some analysis by me.

An active torque dipole across tissue layers drives avian left-right symmetry breaking
Unlike in mice, frogs, and fish, left-right (L/R) body axis formation in avian embryos does not arise from the chiral beat of cilia. Instead, a counter-clockwise tissue rotation around Hensen′ node, t...

🚨 Second preprint of the week!

We uncover the multiscale dynamics of active viscoelastic buckling in epithelia.

We harness these mechanical instabilities for synthetic morphogenesis.
