NASA has made a huge discovery: the ambipolar field, an invisible electric field around Earth that could reshape our understanding of our planet.

In the Earth (see image below right), the liquid metal that makes up the outer core passes through a magnetic field, which causes an electric current to flow within the liquid metal. The electric ...

allowing them to change orientation when exposed to electric fields. This change in orientation affects the light's ability to pass through the liquid crystal layer, enabling the display to produce ...
