Advanced Science, EarlyView.A compact Phe‐Cys‐Pro‐Phe (FCPF) tag and an environment‐sensitive SBD‐Cl‐derived probe form a sequence‐selective fluorogenic pair for wash‐free live‐cell protein imaging. This minimally perturbing chemistry allows flexible insertion at termini or loops, produces strong fluorescence upon local microenvironment confinement, supports FRET‐assisted ...

Angewandte Chemie, EarlyView.ROXendin668 is a peptidic GLP‐1 receptor agonist that generates toxic singlet oxygen upon irradiation with far‐red light. Pancreatic beta cells can be photo‐ablated in a spatiotemporally controlled manner. This approach has the potential to provide a safer alternative to streptozotocin or alloxan for creating model systems for type 1 diabetes research.

Homotopy Perturbation Method for Investigating Population Dynamics in Oxygen-Depleted Environments
Discrete Dynamics in Nature and SocietyThis research will seek to construct a theoretical model to study both the ultraviolet (UV) degradation of hydrogen sulfide (H2S) without oxygen and population dynamics in anoxic environments. Solving some of the issues in biogas energy usage, this paper

Advanced Science, EarlyView.Direct water contact enhances the performance of a transparent self‐powered FTO/ZnO/NiO/AgNW/ZnO UV photodetector. Reduced surface reflection improves optical transmission, while an electric double layer at the ZnO/water interface modulates interfacial electrostatics and promotes charge separation.

Conformationally Switchable Copper(I) Complexes Amplify BODIPY Triplet Photosensitization
Angewandte Chemie, EarlyView.Coupling a structurally switchable Cu(I) complex to an organic light‐harvesting chromophore boosts photoinduced intersystem crossing via the transient formation of a Cu(II) intermediate. Spectroscopic, physical, computational, and photocatalytic studies support this unique new approach to solar energy upconversion.

Angewandte Chemie, EarlyView.A general strategy for 9,10‐phenanthrenequinone‐electron‐rich alkene (PQ‐ERA) photoclick reactions via triplet–triplet annihilation upconversion (TTA‐UC) under low‐intensity green light is reported. A TTA‐UC system of PdOEP (sensitizer) and DPA (annihilator) mixed with reactants generates UV/blue photons overlapping the absorption of PQ derivatives ...

Advanced Science, EarlyView.Engineered heart tissues (EHTs) derived from human iPSCs replicate mechanisms of ventricular tachycardia at the tissue level. Acquired Long‐QT conditions cause early afterdepolarizations, wavebreak, and transient rotors; in contrast, focal cryoinjury forms a stable substrate that supports ongoing reentry.

The potential and pitfalls of de-extinction
, 2016 ‘De-extinction’ is the nascent discipline that aims to one day literally revive now-extinct species from the dead. Although we have yet to see any successful attempts to truly resurrect an extinct species, several technologies are now in place that might
