Polymers experience changing conditions during manufacturing, which can affect their final properties and performance. The way they react to manufacturing forces can be extremely complex and hard to measure. Researchers combined theory and modeling to characterize melted polymers under steady flow and revealed universal features that can inform the design of advanced materials for manufacturing.

A surprising way to trap a microparticle
When physicists steered a tiny microparticle toward a cylindrical obstacle, they expected one of two outcomes to occur. The particle would either collide into the obstacle or sail around it. The particle, however, did neither.
