By making use of randomness, a team has created a simple algorithm for estimating large numbers of distinct objects in a stream of data.

### Game Theory Can Make AI More Correct and Efficient

Researchers are drawing on ideas from game theory to improve large language models and make them more consistent.

### New Breakthrough Brings Matrix Multiplication Closer to Ideal

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

### Scientists Find Optimal Balance of Data Storage and Time

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

### In a ‘Dark Dimension,’ Physicists Search for the Universe’s Missing Matter

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.
