4D Insights into Coral Biomineralization: Effects of Ocean Acidification on the Early Skeleton Development of a Stony Coral

Advanced Science, EarlyView.
Early coral skeletons grow through formation of two co‐joined zones, rapid accretion deposits and thickening deposits. Advanced imaging and simulations reveal that ocean acidification reshapes these zones, shifting the coral portfolio of mineral phases which alters skeletal resistance to mechanical stress.

High‐Asymmetry Metasurface: A New Solution for Terahertz Resonance via Active Learning‐Augmented Diffusion Model

Advanced Science, EarlyView.
A prior knowledge‐guided diffusion model augmented by physics‐constrained active learning is developed to design high‐asymmetry terahertz metamaterials. Trained on only a small set of classical structures, the model efficiently generates new high‐metrics designs.

A Generative Framework for Predicting Antiferromagnets

Advanced Science, EarlyView.
This work establishes a design paradigm for antiferromagnets (AFM), accelerating next‐generation spintronic material discovery. By integrating a crystal diffusion variational autoencoder with data augmentation, crystal graph convolutional neural networks, and a genetic algorithm, latent vectors are updated toward AFM property spaces, expanding ...

A Programmable, 3D Neuron‐On‐Chip Platform Integrating Near Real‐Time Biosensing and Multiaxial Loading for Mechanobiological Injury Profiling

Advanced Science, EarlyView.
A programmable 3D Neuron‐Injury‐on‐a‐Chip platform integrates multiaxial mechanical loading with ultrasensitive electrochemical biosensing to decode neuronal responses in real time. By mimicking physiologically relevant extension–torsion forces, the system reveals load‐specific biomarker trajectories (T‐Tau, NFL), gene regulation, and apoptosis.
