Acinar‐Derived Organoids Reveal Stage‐Specific Control of Acinar Plasticity
Advanced Science, EarlyView.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
Advanced Science, EarlyView.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.

Electron Donor–Acceptor Complex Catalysis in Synthetic Chemistry
Angewandte Chemie, EarlyView.Electron donor–acceptor (EDA) complexes are moving beyond stoichiometric photoactivation toward catalytic platforms for radical generation. Productive EDA catalysis requires coordinated donor–acceptor association, charge‐transfer excitation, radical reactivity, and vcatalyst turnover.

Iodine deficiency and thyroid disorders.
, 2015 Iodine deficiency early in life impairs cognition and growth, but iodine status is also a key determinant of thyroid disorders in adults. Severe iodine deficiency causes goitre and hypothyroidism because, despite an increase in thyroid activity to ...

Photoelectrocatalytic Diazidation of Olefins via Synergistic Dual Iron Species
Advanced Science, EarlyView.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‐

Supramolecular Enforcement of Planar Tetracoordinate Halides
Angewandte Chemie, EarlyView.A calix[4]pyrrolato‐indium scaffold preorganizes Li4 pockets that trap Cl−, Br−, and I− in strongly flattened to square‐planar tetracoordinate environments. Computations reveal low planarization energies for the heavier halides, while crystallography shows that their geometry is readily modulated by subtle supramolecular and packing effects ...
