BES Highlights

The reorganization of nearby water molecules caused a pore in a material built from proteins to open (left) and close (right). Pore closing leads to expulsion of ordered water molecules close to the protein surface.
Knowing how to assemble a porous architecture from proteins able to morph from one shape to another could benefit filtration, other applications.
Shifting the magnetic field relative to the textured surface (left) reconfigures the fluid surface (graded orange indicates relative height; darkest areas are macroscale features).
A flowing magnetically responsive liquid seamlessly regulates the shape and properties of solids, letting them perform an array of jobs.
