Single‐Cell Map of Early Lung Adenocarcinoma Uncovers Invasion‐Associated Tertiary Lymphoid Structures

Advanced Science, EarlyView.
Early thoracic lesions are already heavily infiltrated by immune cells, yet these infiltrates largely consist of bystander T lymphocytes within an immunosuppressive microenvironment. Pathological invasion is strikingly associated with the neogenesis of T/B cell‐rich TLSs that predominantly remain immature.

Broadband Near‐Field Computational Microwave Imaging Enabled by Nonperiodic Dispersive Unit‐Cell Loading in a Passive Metasurface

Advanced Electronic Materials, EarlyView.
A compact passive engineered surface converts changes in microwave frequency into many distinct illumination patterns, allowing nearby objects to be imaged without mechanical scanning, active tuning, or a large antenna array. Operating from 18 to 28 GHz, the single‐port system uses measured field patterns to reconstruct metallic targets and distinguish
