Chinese boffins have emerged from their smoke filled labs having invented some photonic witchcraft that could drive comms gear faster. Electrons in a magnetic field can pull off neat tricks like ...

Who knew that magnetic fields could be so useful? Astronomers are able to use magnetic fields to map our environment within the Milky Way using a technique called Faraday rotation. It works like this.

"The cells we describe are ideally equipped to detect magnetic fields using electromagnetic induction—enabling pigeons to find their way home using the same physical principle which permits the ...
