They tell us about the behaviour of the sun, and galaxies far away; are being used to track sleep in research studies; and tech is changing how radio works too. Radio waves are part of the ...

Such beams of visible light are already used as optical 'tweezers.' Now, the same approach could be applied to radio wavelengths used in telecommunications The research on which this story is based ...

The number of train services on rail networks in Australian cities could eventually increase by 40 per cent because of a recent decision about access to radio bandwidth, operators say. The ...

Automakers attempting to remove AM radio from vehicles has been an ongoing and bizarre battle. Companies want it gone due to claims that the bandwidth can interfere with the newer tech equipped to ...
