Lee Smolin has a radical idea for how to understand an object with no exterior: Imagine it built bit-by-bit from relationships between events.

Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry […]

What do moiré patterns seen in optics, art, photography and color printing have to do with superconducting layers of graphene?

In just three pages, a Russian mathematician has presented a better way to color certain types of networks than many experts thought possible.

Contrary to popular belief, bacteria have organelles too. Scientists are now studying them for insights into how complex cells evolved.

A recent challenge to Stephen Hawking’s biggest idea — about how the universe might have come from nothing — has cosmologists choosing sides.

Immunologists confirm an old hunch: T-cells identify what belongs in the body by timing how long they can bind to it.
