Did your holiday gift list include radiation-shielding undies to protect your privates from cellphone radio waves? A radiation expert explains they’re unnecessary – your phone won’t affect your fertility.
A new development could mean vastly increase data transfer over optical fibre cables.
The design of a new chip to detect the twisted nature of light waves could pave the way for next generation of optical communication technologies.
We find them at the beach, in every sound and light show, the miracle of wi-fi and now in the fabric of space-time itself. But what exactly is a wave?

Warfare is changing, and our approach to dealing with our adversaries must change too.
The Large Hadron Collider is playing a key role in enabling the collection of big data.
Big data is about processing large amounts of data. It is often associated with multiplicities of data. But the ability to generate data outpaces the ability to store it.
