How do sparse mesenchymal cells, with unique stellate arms spanning large gaps between cells, maintain their network while still flowing during development? In our new preprint we describe the avian PSM as a fluid under tension and develop new theory to explain it: www.biorxiv.org/content/10.6...
Sparse mesenchymal cell networks as a fluid under tension
Sparse mesenchymal cellular networks are ubiquitous across animals, shaping both embryonic and adult structures through dynamic interactions with epithelia. Yet, the physical principles underlying the...

Our new paper relating protein folding and jamming is out in PRX Life! All protein cores are densely packed irrespective of overall fold, and we show this arises from a jamming transition where amino acids reach a critical, incompressible density.

Protein Folding as a Jamming Transition
Densely packed protein cores have the same interior packing density irrespective of overall fold, arising from a jamming transition where amino acids reach a critical, incompressible density, as expla...
