(Nanowerk News) When humans, animals, and machines move throughout the world, they always push against something, whether it’s the ground, air, or water. Until recently, physicists believed this to be ...

Electricity can now be bent with lasers, using a technique based on a strange principle of physics. Researchers found they can use lasers to direct the path of electricity, causing the energy to curve ...

If you shine a beam of light from a laser or flashlight, the beam will spread out over distance, becoming wider and less intense far from the source. That phenomenon is called diffraction, and it is ...

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 ...
