Vat Photopolymerized HEMA/HEA Hydrogels for Solvent‐Responsive Transparency and Optical Encryption

Advanced Optical Materials, EarlyView.
Vat‐photopolymerized HEMA/HEA hydrogels exhibit reversible transparency‐opacity switching via hydration‐induced microphase separation and solvent exchange. The printed materials enable hydration sensing, optical encryption, and information storage, while maintaining high ductility and reversible rheology.

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

Advanced Robotics Research, EarlyView.
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.

Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

Advanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

Tim1 Deficiency Mediates Gestational Hyperglycemia‐Related Syncytiotrophoblast Dysfunction and Fetal Growth Restriction

Advanced Science, EarlyView.
Hyperglycemia during pregnancy impairs the fusion of trophoblast cells into syncytiotrophoblasts, leading to fetal growth restriction. This impaired fusion is mediated by Tim1 downregulation via hyperglycemia‐induced ROS. Antioxidant therapy during pregnancy promotes syncytiotrophoblast formation by upregulating Tim1 expression, thus alleviating fetal ...

Engineered Living Systems With Self‐Organizing Neural Networks: From Anatomy to Behavior and Gene Expression

Advanced Science, EarlyView.
Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Electrical Control of the Transduction Channels’ Gating Force in Mechanosensory Hair Cells

Advanced Science, EarlyView.
The inner ear's hair cells rely on mechanosensitive ion channels to convert vibrations of their hair‐bundle into electrical signals. We show that varying the electrical potential (U) across the sensory epithelium modulates a key determinant of mechanosensitivity—the gating force (FG)—by modulating the gating swing (d), ranging from the size of the ...

Metabolic Reprogramming Driven by Trophoblasts and Decidual XCR1+PMN‐MDSC Crosstalk Controls Adverse Outcomes Associated With Advanced Maternal Age

Advanced Science, EarlyView.
The interaction between trophoblasts and decidual polymorphonuclear myeloid‐derived suppressor cells (dPMN‐MDSCs) via the XCL1–XCR1 axis is crucial for fetal development during the third trimester. Disruption of this axis impairs FOXO1 activity and causes metabolic imbalance in dPMN‐MDSCs, contributing to adverse outcomes associated with advanced ...

S3RL: Enhancing Spatial Single‐Cell Transcriptomics With Separable Representation Learning

Advanced Science, EarlyView.
Separable Spatial Representation Learning (S3RL) is introduced to enhance the reconstruction of spatial transcriptomic landscapes by disentangling spatial structure and gene expression semantics. By integrating multimodal inputs with graph‐based representation learning and hyperspherical prototype modeling, S3RL enables high‐fidelity spatial domain ...
