Hygromnemics: Programmable Material Memory Matter Actuators via Wet Pre‐Constraining

Advanced Materials Technologies, EarlyView.
Humidity‐based pre‐constraining creates hygromnemics‐shape memory matter. From identical biocomposites actuation in dry and wet states is obtained via hygromnemic and hygromorphic actuation, respectively. Hygromnemic actuators present long‐ and short‐term shape memory abilities.

Acoustic Wavefront Shaping Using Ultrahigh Phase Resolution Metamaterial

Advanced Materials Technologies, EarlyView.
A Bilateral Symmetrical T‐shaped (BST) acoustic metamaterial unit cell capable of achieving a high phase resolution of π/36 radians at 8000 Hz is introduced. The approach enables tunable wavefront control through simple rotational adjustment of BST, which offers an alternative to the conventional complex metamaterials unit cell design and a way for ...

Gallium β‐Cyclodextrin Nanoparticles Containing both Gallium Protoporphyrin and Gallium Nitrate Exhibit Antimicrobial Activity against Nontuberculous Mycobacteria in Vitro and in Vivo

Advanced Therapeutics, EarlyView.
Cyclodextrin nanoparticle containing both Ga(NO3)3 and GaPP is synthesized and tested against non‐tuberculous mycobacteria (NTM). The in vivo efficacy of the nanoparticle therapy is additionally tested by treating pulmonary NTM infections in mice and observed much greater effectiveness in bacterial clearance and survival of mice.

RELA Ablation Contributes to Progression of Hepatocellular Carcinoma with TP53R249S Mutation and is a Potential Therapeutic Target

Advanced Science, EarlyView.
Genome‐wide CRISPR/Cas9 based screening identified RELA as a key tumor suppressor in TP53R249S‐mutant HCC. Its loss promotes tumorigenesis and metastasis via DVL1‐mediated Wnt/β‐catenin activation, while its agonist betulinic acid suppresses tumor progression.
