Colloidal particles at fluid interfaces may strongly hinder or barely affect mass transfer. Using the Fick-Jacobs equation, a new Letter shows that hindrance occurs mainly at short times from reduced cross-section, giving a simple predictive criterion. go.aps.org/4hTKEJR

APS 2025: See You in Houston, Texas! 🤠 APS looks forward to welcoming you to Houston, Texas, from November 23–25, 2025! Today is the last day to register at regular rates 👻 Wishing everyone a Happy Halloween — add a little fun to your day as you plan your trip to Houston! 🎃

Turbulence drives heterogeneous particle adhesion in channel flows, with adhesion strength rising at higher temperatures. DNS show that deposition depends on particle inertia and is shaped by turbulent structures. Read the PRFluids Editors’ suggestion: go.aps.org/4hjW6OK

A two-sphere microswimmer made of responsive hydrogels can move through viscous fluids by swelling and deswelling in response to chemical waves. A model shows how swimming speed depends on the asymmetry of the gel spheres, enabling chemoresponsive motion. go.aps.org/4nDwdf4
