Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation
Advanced Materials, EarlyView.Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

De Rerum Natura: How Do Halide Perovskites Self‐Heal From Damage?
Advanced Materials, EarlyView.How can lead‐halide‐perovskites self‐heal after damage from light, heat, mechanical strain, or radiation? We show that reversible chemical defects underly performance losses and recovery, highlighting the roles of halide and proton migration, redox‐driven reactions, and acid‐base equilibria.
