A scalable laser‐assisted surface patterning method regulates zinc ion flux and promotes lateral epitaxial growth for stable aqueous batteries. Periodic micro‐holes effectively minimize interfacial resistance and reconstruct the zinc texture to favor the compact (002) basal plane. This structured anode suppresses both dendrite propagation and parasitic

Acinar‐Derived Organoids Reveal Stage‐Specific Control of Acinar Plasticity
An acinar‐derived organoid system maintains adult pancreatic acinar identity ex vivo, converts it along an ordered acinar‐to‐ductal‐like trajectory, and then partially restores it. Each transition carries its own signal requirement, with EGF/EGFR initiating conversion and a staged glucocorticoid–IGF1R switch driving redifferentiation.

Hypothalamic POMC Neurons Gate the Fear‐Feeding Trade‐Off
Hungry animals must continually arbitrate between feeding and defensive behaviors when confronted with potential threats. We show that hypothalamic POMC neurons engage CRH‐expressing stress circuits and downstream hormonal responses to coordinate this behavioral selection between competing behaviors.

ABSTRACT Extracellular vesicle therapies have been developed for tissue repair, but how donor‐cell senescence reshapes vesicle‐mediated mitochondrial transfer remains unclear. Here, we show that senescent adipose‐derived stem cells (ADSCs) redirect damaged mitochondria into microvesicles (MVs), converting protective vesicles into pro‐degenerative ...

Photoelectrocatalytic Diazidation of Olefins via Synergistic Dual Iron Species
We report a simple and general approach for 1,2‐diazidation of alkenes by a photoelectrochemical strategy using TMSN3 as an azide source. This transformation proceeds using earth‐abundant iron under mild reaction conditions. It displays broad functional group compatibility and accommodates diverse alkene types‐including unactivated, activated, electron‐

Highly Linear Perovskite Synapses for Neuromorphic Computing
Voltage spikes applied to an Au/ACI‐phase perovskite/ITO memristor emulate the ionic signaling of a biological synapse, generating a tunable postsynaptic current. The vertically aligned perovskite film confines iodide‐vacancy migration, enabling highly linear, and symmetric conductance updates with 100 states and 5.5 aJ per event. Such synapses sustain
