1/2 Could we one day train living matter through experience? We’re exploring a step in that direction.
In our new @PNASNexus paper with @ShilaBanerji, we show how this can work in a tissue model.

2/2 Local contractions produce lasting changes in its mechanics and leave memories that affect later responses. With repeated mechanical stimuli, we can also train its elastic properties, even making it auxetic: it widens sideways when stretched.

How does the brain, which uses ~20% of the body’s energy, make and ration its power? Today the @SimonsFdn launches SCOBE: $80M, 10 years, 26 investigators, including the Allen Institute’s Anton Arkhipov.

Ecstatic to share that WE GOT THE COVER! 🥹🎉
Seeing this on NCB's cover feels surreal. So much time, science, and teamwork went into this project, and I couldn’t be more excited to see it celebrated like this.
A very very happy day for this really really old and grown embryo 🐭
🧵 What if one reason fertility declines with age isn’t just genetic-but mechanical?
Thrilled to share our new paper in @NatureCellBio:
Elevated contractility drives implantation failure in mouse embryos from aged females… here’s what we found 👇

Happy to share a new preprint from my group on polarity-resolved imaging of active Janus nanoparticles in liquid-phase TEM, led by @isabelpanicker and in collaboration with @katy_requejo, @moshe_assaf, and colleagues at UC Berkeley, UChicago, and the @molecularfndry.
If you have ever wondered which direction the catalytic side of a nanomotor is pointing when it makes active jumps, we can now visualize that directly for ~100 nm particles. Using the power of liquid-phase TEM together with SAM-EM, we can distinguish the high-contrast Pt side from the low-contrast polystyrene side and correlate particle polarity with its motion in the presence of chemical fuel.
If you want to read more, check out the manuscript!

1/6 Can learning in physical systems help us understand how embryos shape themselves?
Our PNAS paper with Andrea Liu & @ManningResearch introduces a tunable-matter framework for morphogenesis, using convergent extension as a case study.

5/6 Every strategy achieved elongation; but left a distinct mechanical and geometric fingerprint.
Only the length-and-orientation rule matched experimental cell shape, junction alignment, and high-tension patterns.

Cell intercalation is an exchange of cell neighbours. Now it is shown in a minimal system of four cells that intercalation is driven by junction tension and migratory forces.

Tissue phase transitions are key to morphogenesis. Now adhesion-driven rigidification is identified as key to epithelial organization but only if uncoupled from density-driven jamming.
