Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

NNMT Orchestrates Metabolic‐Epigenetic Reprogramming to Drive Macrophage‐Myofibroblast Transition in Hypertrophic Scarring

open access: yesAdvanced Science, EarlyView.
In macrophage‐myofibroblast transition, upregulated NNMT depletes S‐Adenosylmethionine‌ (SAM) and nicotinamide adenine dinucleotide(NAD+), thereby triggering epigenetic reprogramming via Histone H3 Lysine 27 acetylation (H3K27ac) accumulation at the promoter region of master transcription factor Prrx1.

Anisotropically Wettable Porous Transport Layers for Gas Management in Water Electrolyzers

open access: yesAdvanced Science, EarlyView.
Synergistic wetting, achieved by integrating hydrophilic and hydrophobic domains, enhances mass transport in porous transport layers. In situ visualization reveals that dual‐phase wetting suppresses gas accumulation and promotes continuous bubble release, enabling stable, bubble‐free electrolysis within membrane electrode assemblies.

Nuclear Weapon and Military Equipment

open access: yesDefence Science Journal, 1985
Military equipment must survive a, nuclear attack if enough personnel required to operate them remain combat effective. To achieve this goal, the criteria that determine equipment survivability should be established and any new design should incorporate these criteria to evolve a hardened design.

CHB‐Induced Immune Zonation Chaos Elicited LXRα‐mediated Lipid Metabolism Disorders in Kupffer Cells to Induce Cancer Stem Cell Formation

open access: yesAdvanced Science, EarlyView.
By profiling the spatiotemporal hepatic landscape of CHB mouse models, the originally peri‐portal localized KCs migrated to the peri‐central in a CXCL9‐CXCR3‐dependent manner, facilitating their interaction with HBV+ hepatocytes. The interaction promoted LMD in KCs through ASGR1‐induced LXRα degradation, which, in turn, induced CSC formation via Stat3 ...
