<< Cells comprising a tissue can pack into disorderly geometries much as do grains of sand in a sandcastle. In doing so they can freeze into a fixed shape—as in a sandcastle—or flow like sand poured from a beach bucket >>
<< This finding makes a deep connection between the physics of inert granular matter such as sand and the geometry of multicellular living systems >> Lior Atia.
