Combinatorial Design of Textured Mechanical Metamaterials

[source] We show how to assemble an astronomical number of distinct smart materials that each recognize and morph into a unique shape. To design these, we stack copies of one oriented building block, and crack the three-dimensional jigsaw puzzle that governs the placement of these blocks.

Shape Regulation and Elastic Interactions between Living Cells

[source] Live cells exert contractile forces, which result in elastic deformations of their environment. Cells in live tissue measure the resultant forces and displacements created on their surfaces by neighboring cells and in response correct their own forces in some preprogrammed way.
