We all use antennas for radios, cell phones, and WiFi. Understanding how they work, though, can take a lifetime of study. If you are rusty on the basic physics of why an antenna radiates, have a look ...

I hope that you are never in a situation in which you are in danger from a downed, but live, power line. However, if that ever happens, the recommended safety procedure is to move away with tiny, ...

Researchers have discovered a technique for controlling light with electric fields. Researchers from North Carolina State University have discovered a technique for controlling light with electric ...

Normally, semiconductors don't have many free electrons. Since electric current relies on those free electrons, the amount of current that can travel through an isolated semiconductor is negligible.

Spiders don’t have wings, but they can fly across entire oceans on long strands of silk. For more than a century, scientists thought it was the wind that carried them, sometimes as high as a jet ...

Researchers at University of Tsukuba have successfully measured electric fields near the surfaces of two-dimensional layered ...

A new gadget takes advantage of sharks’ sixth sense to send the fish scurrying away from deadly hooks. Sharks, rays and their relatives can detect tiny electric fields, thanks to bulbous organs ...
