Anomalous Diffusion by Fractal Homogenization
Annals of PDEFor every $α< \frac13$, we construct an explicit divergence-free vector field $\mathbf{b}(t,x)$ which is periodic in space and time and belongs to $C^0_t C^α_x \cap C^α_t C^0_x$ such that the corresponding scalar advection-diffusion equation $$\partial_t θ^κ+ \mathbf{b} \cdot \nabla θ^κ- κΔθ^κ= 0$$ exhibits anomalous dissipation of scalar variance ...

Intelligent Soft Opto‐Magnetic Robot for Minimally Invasive Interventional Therapy
Advanced Science, EarlyView.An intelligent soft opto‐magnetic (iSOM) robot is developed that integrates remote magnetic actuation, skin‐mimic tactile perception, and photothermal ablation in a near‐millimeter‐scale design. It enables precise intraluminal navigation and localized ablation while providing real‐time optical feedback to support safe and accurate minimally invasive ...

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities
Advanced Science, EarlyView.T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Leaky‐Integrate‐Fire Neuron via Synthetic Antiferromagnetic Coupling and Spin‐Orbit Torque
Advanced Science, EarlyView.A spintronic leaky‐integrate‐and‐fire neuron is realized using Spin Orbit Torque driven domain‐wall motion for integration and synthetic antiferromagnetic coupling for the leaky process. The specialized Hall‐bar geometry enables controlled DW dynamics, achieving repeatable integration and firing events. This compact, CMOS‐compatible design highlights a

Advanced Science, EarlyView.This study elucidates mass transport dynamics within polybromide ionic liquids in dual‐plating zinc–bromine batteries using operando impedance spectroscopy. The findings reveal that sluggish polybromide transport during dissolution contrasts with rapid bromide transport during charging.
