NASA scientists have discovered a third global energy field around Earth. Known as the ambipolar electric field, this force drives charged particles into space above the poles. Two major global energy ...

In the home, the lab and the factory, electric fields control technologies such as Kindle displays, medical diagnostic tests and devices that purify cancer drugs. In an electric field, anything with ...
