Nature’s large-scale patterns emerge from incomplete surveys that borrow ideas from information theory.

Newly discovered particles are forcing physicists to extend their simple picture of subatomic interactions or replace it with a more nuanced understanding.

Our bodies are a genetic patchwork, possessing variation from cell to cell. Is that a good thing?

Physicists have begun to explore the idea that mass and length may not be fundamental properties of nature. The hypothesis could help to avoid the conclusion that our world is just a weird bubble in an endlessly foaming multiverse.

Subhash Khot’s bold conjecture is helping mathematicians explore the precise limits of computation.

Martin Hairer was named a 2014 Fields medalist for an epic masterpiece in stochastic analysis that colleagues say “created a whole world.”
