A mutant seedling revealed how plant tissues scatter incoming light, allowing plants to sense its direction and move toward it. On a shelf lined with terra cotta pots, herbs bend their stems toward ...

Scientists have engineered a type of artificial optical material -- a metamaterial -- with a particular three-dimensional structure such that light exhibits a negative index of refraction upon ...

Researchers fabricated an optical element that uses a forest of tiny, antenna-like nanorods, seen here, that together create a metamaterial able to control the spin of light. The metamaterial nanorods ...
