Researchers have engineered a material that could lead to a new generation of computing devices, packing in more computing power while consuming a fraction of the energy that today's electronics require.

The improvement results from techniques that allow computer processors to retrieve data more efficiently.

Machine learning can predict strains of bacteria likely to cause food poisoning outbreaks, research has found.

"Such a network will enable secure communication without having to worry about eavesdropping, and allow distant quantum computers to connect." 

A computer science expert weighs in. 

Augmented reality (AR), where the correct placement of virtual content is not only crucial, but a matter of life and death.

But in practice, this isn't always the case.

And it doubles the range of signal.
