Advanced Science, EarlyView.Meniscus splitting in the drying of a viscous polymer dispersion is investigated by focusing on nucleation of multiple nuclei with symmetry breaking and asynchronous nucleus formation. Controlled by spatial boundaries, the first nucleus is generated at a position shifted away from the space center and strongly facilitates the asynchronous second ...

High‐Throughput MicroED for Probing Ion Channel Dynamics
Advanced Science, EarlyView.High‐throughput MicroED offers a new approach for visualizing ion channel dynamics. This approach reveals NaK’s sodium binding modes and NaK2CNG’s potassium‐induced selectivity filter dilation and gating. By capturing these distinct structures, this work challenges traditional models of ion channel permeation and selectivity. Abstract Ion channels play
