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 ...

In a recently published article in the journal Physics Letters B, researchers investigated the propagation of light within a theoretical model known as an elliptic wormhole (EWH), characterized by ...

It could be argued that there is no right or wrong way to eat a slice of pizza. However, according to a 19th century mathematician the only way to devour a cheesy slice is to fold it in a U-shape.
