A theorem for coloring a large class of “perfect” mathematical networks could ease the way for a long-sought general coloring proof.

Complex natural systems defy analysis using a standard mathematical toolkit, so one ecologist is throwing out the equations.

Only a few genetic changes were enough to change an ordinary stomach bug into the bacteria responsible for the plague.

A major advance in computational complexity reveals deep connections between the classes of problems that computers can — and can’t — possibly do.

Nima Arkani-Hamed is championing a campaign to build the world’s largest particle collider, even as he pursues a new vision of the laws of nature.

Cellular clocks are almost everywhere. Clues to how they work are coming from the places they’re not.

Einstein refused to believe in the inherent unpredictability of the world. Is the subatomic world insane, or just subtle?

A recent cryptographic breakthrough has proven difficult to put into practice. But new advances show how near-perfect computer security might be surprisingly close at hand.

The mathematician John Horton Conway’s myriad accomplishments — including the Game of Life, sprouts and the surreal numbers — are the product of a mind at play.
