Mathematicians have studied knots for centuries, but a new material is showing why some knots are better than others.
While studying materials made from DNA-coated nanoparticles, researchers found a new form of this matter: lattices in which smaller particles roam like electrons in metallic bonds.
What do moiré patterns seen in optics, art, photography and color printing have to do with superconducting layers of graphene?
The stunning emergence of a new type of superconductivity with the mere twist of a carbon sheet has left physicists giddy, and its discoverer nearly overwhelmed.
People have known about magnets since ancient times, but the physics of ferromagnetism remains a mystery. Now a familiar puzzle is getting physicists closer to the answer.
