Topology‐Enriched Toughness Enhancement in Quasi‐Periodic Metastructures Featuring Tailorable Strong‐Weak Network

open access: yesAdvanced Science, EarlyView.
A quasi‐periodic Dart‐Kite (QDK) metastructure with a golden‐ratio‐constrained strong–weak bond network simultaneously enhances strength, toughness, and damage tolerance. Its distributed topology enables predictable, tailorable crack paths for precise fracture control and stable mechanics, demonstrating a high‐performance, controllable architecture ...

Aptamer‐Directed Porous DNA Nanocomposite Hydrogel for Active Pulp Preservation: Immunomodulation, Stem Cell Recruitment and Reparative Dentinogenesis

open access: yesAdvanced Science, EarlyView.
This study presents an injectable DNA‐based porous hydrogel integrating catechol motifs and targeting aptamers for pulpitis management. Upon in situ crosslinking, the scaffold actively recruits endogenous dental pulp stem cells, restores redox homeostasis, and modulates immune responses.

A Bone Marrow–Mimetic Hydrogel Enables Dual‐Phase Hemostasis and Vascularized Osteogenesis for Cranial Defects

open access: yesAdvanced Science, EarlyView.
A biomimetic, fiber‐reinforced hydrogel (FE‐PDA@Fib/Gel‐TG) that enables dual‐phase cranial defect repair. The system provides: instant hemostasis in the early stage, and sustained co‐delivery of pro‐angiogenic and osteogenic signals for synergistic vascularized bone regeneration.

Tumor‐Infiltrating mregDCs Restrain Anti‐Tumor Immunity in Early Relapse HCC

open access: yesAdvanced Science, EarlyView.
Tumor‐infiltrating mregDCs are regulated by the TNFR2‐non‐canonical NF‐κB axis, which is mediated by TNF‐α secreted by CD161+CD8+ T cells. These mregDCs recruit CD161+CD8+ T cells via the CCL20‐CCR6 axis, forming a positive feedback loop that enhances immunosuppression, promotes early recurrence of HCC, and further confirms TNFR2 as a key therapeutic ...

Inhibitory Decay and Supercritical Brain Dynamics During Sleep Deprivation

open access: yesAdvanced Science, EarlyView.
Sleep deprivation progressively shifts human brain dynamics from near‐critical toward supercritical states, as revealed by neuronal avalanche analysis of resting‐state fMRI. These changes track subjective sleep pressure rather than vigilance lapses and show marked network heterogeneity. A circuit model suggests that reduced inhibitory efficacy provides

NLSS3 Impairs SHM1 Autophagic Degradation to Regulate Leaf Morphology and Salt Tolerance in Rice

open access: yesAdvanced Science, EarlyView.
In rice, NLSS3 binds and shields SHM1 from autophagic degradation to maintain serine homeostasis. The A132P mutation in nlss3 disrupts this, triggering SHM1 loss, metabolic dysfunction, K+ imbalance, and impaired ROS scavenging, which collectively drive narrow leaves and salt sensitivity.

Targeting ANGPTL3 and IL‐33/ST2 Ameliorates Diabetic Kidney Disease by Reducing Lipotoxicity, Alleviating Inflammation and Inhibiting Fibrosis

open access: yesAdvanced Science, EarlyView.
Dual targeting of ANGPTL3 and IL‐33/ST2 attenuates diabetic kidney disease by reprogramming lipid–inflammatory crosstalk. This strategy reduces renal lipotoxicity, suppresses inflammatory activation, and limits fibrotic remodeling, thereby preserving kidney structure and function and highlighting a mechanism‐guided therapeutic approach for metabolic ...
