Surface Graphitized Mesoporous Carbon Surpasses the Conductivity–Porosity Trade‐Off

open access: yesAdvanced Science, EarlyView.
Electrochemical cathodic polarization in molten CaCl2‐NaCl converts mesoporous carbon (MC) into surface‐graphitized mesoporous graphite, simultaneously increasing surface area (397–867 m2/g) and electrical conductivity (26–450 S/cm) without mass loss.

Bidirectionally Thermochromic Nanocolloid System for on‐Demand Optical Switching and Agricultural Energy Management

open access: yesAdvanced Science, EarlyView.
A bidirectionally thermochromic nanocolloid system is developed for facility agriculture. The bidirectional and wide‐temperature response dynamically modulates light radiation, stabilizing the indoor climate, improving supplemental lighting efficiency, and accelerating plant photosynthesis.

ACSL1‐Dependent Microglial Lipoimmunometabolic Reprogramming Underlies Cognitive Deficits in Alcohol Use Disorder

open access: yesAdvanced Science, EarlyView.
This study reveals that chronic alcohol exposure selectively upregulates ACSL1 expression in prefrontal cortical microglia, driving lipid metabolism reprogramming and lipid droplet accumulation, which activates the NLRP3 inflammasome and sustains neuroinflammation. To reverse this process, a dual‐targeted lipid nanoparticle, siACSL1@LNP‐MR, is designed

Neuronal Cholesterol Deficiency Mediated by Astrocytic SREBP2 Downregulation Leads to Postoperative Cognitive Dysfunction Through Impairment of Hippocampal Synaptic Plasticity and Excitatory Synaptic Transmission

open access: yesAdvanced Science, EarlyView.
The results showed that the reduction of plasma 24‐hydroxycholesterol (24‐OHC) was related to the cognitive decline in elderly surgical patients. Neuroinflammation induced by anesthesia and surgery significantly downregulated SREBP2 in hippocampal reactive astrocytes, resulting in reduced cholesterol synthesis.

Endothelial PDGF Signaling Dysregulation Impairs Testicular Interstitial Homeostasis in Diabetes

open access: yesAdvanced Science, EarlyView.
Testicular endothelial cells (TECs) function as central signaling hubs that coordinate interstitial homeostasis. Diabetes disrupts TEC‐derived PDGF signaling, silences the JUND‐MCL1 survival program in Leydig cells, and impairs peritubular function, leading to fibrosis and testosterone insufficiency.

A Subset of Pro‐inflammatory CXCL10+ LILRB2+ Macrophages Derives From Recipient Monocytes and Drives Renal Allograft Rejection

open access: yesAdvanced Science, EarlyView.
This study uncovers a recipient‐derived monocyte‐to‐macrophage trajectory that drives inflammation during kidney transplant rejection. Using over 150 000 single‐cell profiles and more than 850 biopsies, the authors identify CXCL10+ macrophages as key predictors of graft loss.
