Focus: Understanding a Spreading Puddle

Classical fluid theory can’t explain a puddle that spreads and then stops. A new theory solves the problem by incorporating intermolecular forces between the liquid and the solid underneath. Read More »

Synopsis: Good Vibrations

With the assistance of lattice vibrations, quantum dots perform as single-photon emitters. Read More »

Notes from the Editors: Highlights from the Physics of Active Matter Conference

At the meeting, researchers presented new models to describe the developing wing of a young fly, colloidal particles that propel themselves, and the liquidlike behavior of cell colonies . Read More »
