Inspired by the cells in leaves that control leaf curvature to regulate water loss, researchers present flat panels that can morph into a stiff, complex 3D structure with a different Gaussian ...

Positive curvature, like that on a sphere, implies a finite universe, while zero curvature, as on a flat plane or negative ...

Cells can sense and respond to surface curvature in very clever ways, as shown in research. The results, which revealed that curvature is a profound biological cue, could pave the way to new tools in ...
