Angewandte Chemie, EarlyView.The azacitidine biosynthetic gene cluster (aza BGC) was identified by the resistance‐gene‐guided comparative genomics method in Streptomyces mobaraensis IPIO2. The complete biosynthetic pathway of azacitidine, which follows a “base‐first‐then‐glycosylation” logic, was elucidated through in vivo and in vitro experiments.

Hydration‐Gated Photoinduced Electron Transfer in BODIPY Dyes
Angewandte Chemie, EarlyView.Hydration switches photoinduced electron transfer (PET) ON in alkoxy‐coordinated BODIPY dyes via specific hydrogen bonding. This gating yields a fluorescence lifetime span of ∼6 ns, enabling fluorescence lifetime imaging microscopy (FLIM) contrast in live cells and organoids. ABSTRACT Fluorescent probes based on photoinduced electron transfer (PET) are

A TALE OF TWO CITIES: DIET, HEALTH AND MIGRATION IN POST-MEDIEVAL COVENTRY AND CHELSEA THROUGH BIOGRAPHICAL RECONSTRUCTION, OSTEOARCHAEOLOGY AND ISOTOPE BIOGEOCHEMISTRY [PDF]
, 2006 Biogeochemical research has over the past four-and-a-half decades improved our understanding of human interaction with past environments. The application of different isotope systems has allowed archaeologists to interpret ancient diet, migration and ...

Template‐Encoded Assembly and Adaptive Function in Selenium‐Based Molybdenum Chalcoxide Rings
Angewandte Chemie, EarlyView.External templates write structural information into Se‐containing molybdenum rings, while selenium's softness confers adaptive host–guest behaviour and catalytic responsiveness, an integrated framework for programmable inorganic function. ABSTRACT Controlling both structure and function in inorganic self‐assembly remains a major challenge.

Angewandte Chemie, EarlyView.Direct synthesis of sulfonimide‐based polymers of intrinsic microporosity enables comparison with compositionally similar flexible analogs. Incorporation of a common pore‐filling transport medium drives these fundamentally different polymer architectures toward similar bulk conductivity and mechanical properties while revealing distinct microscopic ion‐

Redox‐Modulated σ‐Bond Reactivity in a Radical‐Anion Dimer
Angewandte Chemie International Edition, Volume 65, Issue 44, 26 October 2026.A radialene‐based radical anion σ‐dimer comprising an elongated C‐C bond exhibits orthogonal stimuli responsiveness. Homolytic cleavage of the dimer to the radical state is triggered by mechanical strain and high temperature. Dimer scission is also achieved via oxidation, resulting in formation of neutral radialenes.
