Inspired by the results of a game-playing neural network, mathematicians have been making unexpected advances on an age-old math problem.

An energy-efficient chip called NeuRRAM fixes an old design flaw to run large-scale AI algorithms on smaller devices, reaching the same accuracy as wasteful digital computers.

Lattice cryptography promises to protect secrets from the attacks of far-future quantum computers.

A team of physicists has entangled three photons over a considerable distance, which could lead to more powerful quantum cryptography.

Harry Halpin wants our internet conversations to be more private. He’s helped create a new kind of network that might make it possible.

Zero-knowledge proofs allow researchers to prove their knowledge without divulging the knowledge itself.

Efforts to build a better digital “nose” suggest that our perception of scents reflects both the structure of aromatic molecules and the metabolic processes that make them.

A simple geometric idea has been used to power advances in information theory, cryptography and even blockchain technology.

A custom-built machine learning algorithm can predict when a complex system is about to switch to a wildly different mode of behavior.
