Plants droop and shed their leaves when parched, but with a splash of water, their stems regain strength and their leaves ...

The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in vacuum. However, in so-called epsilon-near-zero (ENZ) materials, light exhibits ...
