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.

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

Neural networks originally designed for language processing turn out to be great models of how our brains understand places.

What’s a message, really? Claude Shannon recognized that the elemental ingredient is surprise.

Anima Anandkumar wants computer scientists to move beyond the matrix, among other challenges.
