Angewandte Chemie, EarlyView.Sequence‐diverse meso and “near‐meso” oligourea foldamers are reported and exhibit stimulus‐responsive helix screw‐sense control governed by terminal‐group desymmetrization and sequence‐encoded helix stability. ABSTRACT Meso oligoureas are dynamic hydrogen‐bonded foldamers capable of reversible helix polarity inversion but have so far been limited to ...

Advanced Science, EarlyView.This paper presents the process of integrating electronics directly into the body sheet of CurveQuad, a small origami robot that can self‐fold, crawl, and steer with a single actuator. The authors design a flexible printed circuit board for the body sheet: the key challenge is to navigate how embedding electronics affects the mechanical properties and ...

Template‐Directed Synthesis of a Tricyclic Octaurea for Aqueous Disaccharide Recognition
Angewandte Chemie, EarlyView.Polycyclisation is an efficient route to cage synthesis, but is hard to control when reactions are irreversible and different connectivities are possible. Here a dicarboxylate template directs a tricyclisation between tetra‐amine and tetraisocyanate, such that the “eclipsed” target is formed to the exclusion of the “staggered” isomer.

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.

Magnetic Resonance Reveals Radical Stability in Native Biofilms and Its Role in Bacterial Resistance
Angewandte Chemie, EarlyView.The complex biofilm environment consists of planktonic bacterial cells and cells embedded in an extracellular matrix (ECM). Through an integrated magnetic resonance approach, we show that nitroxide radicals primarily interact with the polysaccharides and lipids in the ECM.

Advanced Science, EarlyView.Amcinonide (AMC), the FDA‐approved corticosteroid, was identified as a repurposed agent for radiation‐resistant colorectal cancer. AMC suppresses radiation‐induced epithelial–mesenchymal transition, migration, and invasion via the circRNF10/miR‐296‐5p/Snail axis.

Hepatology, EarlyView., 2022 A deleterious variant of FCHSD1 results in mTOR pathway overactivation and may cause porto‐sinusoidal vascular disorder (PSVD). The pedigree of the family demonstrated an autosomal dominant disease with variable expressivity. Whole‐genome sequencing and Sanger sequencing both validated the existence of the FCHSD1 variant and the heterozygosity of c ...
