By eliminating a hidden inefficiency, computer scientists have come up with a new way to multiply large matrices that’s faster than ever.

Seventy years after the invention of a data structure called a hash table, theoreticians have found the most efficient possible configuration for it.

An idea derived from string theory suggests that dark matter is hiding in a (relatively) large extra dimension. The theory makes testable predictions that physicists are investigating now.

As computer-driven cars and planes become more common, the key to preventing accidents, researchers show, is to know what you don’t know.

Mathematicians prove a theorem that illuminates the geometry of universes with tiny amounts of mass.

Eugenio Calabi, who died on September 25, conceived of novel geometric objects that later became fundamental to string theory.

Some modern image generators rely on the principles of diffusion to create images. Alternatives based on the process behind the distribution of charged particles may yield even better results.

For a half century, mathematicians have tried to define the exact circumstances under which a black hole is destined to exist. A new proof shows how a cube can help answer the question.

A novel type of neural network is helping physicists with the daunting challenge of data analysis.
