Living organisms absorb external nutrients to grow, changing their macroscopic shapes to meet various challenges through mass transport and integration. While several strategies have been developed to ...

The cell cortex is defined as a thin layer of filamentous actin, myosin motors, and regulatory proteins beneath the plasma membrane. Assembly and contraction of this actin meshwork generates cortical ...

High crosslinking and low shrinkage stress are difficult to reconcile in the preparation of performance-enhancing photopolymer materials. Here we report the unique mechanism of upconversion ...
