What's up in

The impasse in math and science instruction runs deeper than test scores or the latest educational theory. What can we learn from the best teachers on the front lines?

When divvying something up, there’s more than one way to define what’s fair.

Computer scientists have come up with a bounded algorithm that can fairly divide a cake among any number of people.

Computer scientists can prove certain programs to be error-free with the same certainty that mathematicians prove theorems.

Recent tests show that quantum computers made by D-Wave systems should solve some problems faster than ordinary computers. Researchers have begun to map out exactly which queries might benefit from these quantum machines.

A project to decipher the brain’s learning rules could revolutionize machine learning.

The Go-playing program teaches itself to replicate something very much like human intuition, an advance that promises far-reaching consequences.

The biological world is computational at its core, argues computer scientist Leslie Valiant.

Computer scientists are abuzz over a fast new algorithm for solving one of the central problems in the field.
