Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary ...

With two light barriers closely positioned one after the other it is possible to establish in which direction they have been crossed. If, for example, you place it at the entrance of the toilet then ...

Future iPhone cameras that capture the direction light is traveling may provide greater 3D detail that will improve Apple AR walk-through experiences. Current iPhone cameras capture the intensity of ...

Today I would like to present the turbine-powered optical isolator, a steampunk-sounding bit of hardware that only allows light to pass in one direction. That, I must admit, is a sentence I never ...

Researchers have identified key structures in photosensitive plant tissue that allow them to determine the direction of light, leading to positive phototropism. A recent research collaboration between ...

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 ...

Researchers found how plants, which have neither brains nor eyeballs, understand how to grow in the direction of light. Plants don't have eyes but somehow know how to stretch toward the light — in ...
