When Mechanics Rewrites Chemistry: Divergent Pathways of Hardening and Softening in High Strength Al‐Alloys

open access: yesAdvanced Science, EarlyView.
Mechanics reshapes chemistry: plastic flow actively governs two divergent, atomic‐scale mechanochemical pathways that tailor strain localization and ductility in high‐strength 7xxx Al alloys. Rather than relying on static structures, deformation dynamically reinforces the solution‐treated state via clustering, yet destabilizes the peak‐aged condition ...

A Tumor‐Boundary Niche Enriched for PD‐1+CD8+T Cells and BTLA+B Cells Drives Resistance to Immunotherapy in NSCLC

open access: yesAdvanced Science, EarlyView.
A spatial niche composed of BTLA+B cells and CD8+T cells is enriched at the tumor boundary in non‐small cell lung cancer. Within this specialized niche, BTLA+B cells act as a dominant source of IL‐6, upregulating PD‐1 on CD8+T cells via STAT3 signaling.

Acid‐Responsive Nanobot‐Integrated Core‐Shell Microneedles Reprogram the Degenerative Annulus Fibrosus Microenvironment Through Epigenetic Suppression of Ferroptosis

open access: yesAdvanced Science, EarlyView.
An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

Printing‐Assisted Integration of Thermal, Fluidic and Electrical Components in Implants for Focal Brain Cooling

open access: yesAdvanced Science, EarlyView.
Extrusion‐based 3D printing of silicones and discrete electronic components are combined to create cortical implants for rodents that integrate thermal neuromodulation and electrical recording. Linked to an autonomous auxiliary driver unit, the system enables rapid, stable and localized hypothermia alongside ECoG recording.

Granzyme B PET Imaging Reveals Lgmn+ Macrophage‐Mediated Immune Evasion and Guides Immunotherapy in EGFR‐TKI‐Resistant NSCLC

open access: yesAdvanced Science, EarlyView.
Graphical illustration of 68Ga‐GZB PET/CT imaging reveals immune dynamics post‐EGFR‐TKI resistance in NSCLC; Lgmn+ macrophages‐derived Lgmn‐containing extracellular vesicles inhibit glycolysis, induce CD8+ T cell exhaustion, and targeting Lgmn restores immunotherapy sensitivity.
