Dynamic Fibrous Hydrogels for Stem Cell Homing and In Situ Bone Regeneration

open access: yesAdvanced Science, EarlyView.
A dynamic fibrous hydrogel (DFH) is developed by covalent crosslinking of gelatin with tea‐derived trichomes, which integrates the structural and compositional fidelity of native extracellular matrix with photothermal and oxidative responsiveness, introducing a novel “stem cell recruits stem cell” strategy that orchestrates co‐homing of endogenous and ...

A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring

open access: yesAdvanced Science, EarlyView.
Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Allelic Variation in Maize Malate Dehydrogenase 7 Shapes Promoter Methylation and Banded Leaf and Sheath Blight Resistance

open access: yesAdvanced Science, EarlyView.
In this study maize chloroplastic malate dehydrogenase7 (ZmMDH7), is identified as a Rhizoctonia solani resistance gene in maize. ZmMDH7 is regulated by transcription factor ZmWRKY44 via pathogens challenge to elevate mitochondrial ROS and SA signaling pathway.

Operating Point Control System in Single-Phase Motor Pump Sets Used in Irrigation Systems: Development and Evaluation

open access: yesAgriEngineering
Fixed irrigation systems often experience uneven water pressure across different sections, making it challenging to irrigate all areas efficiently without wasting energy. This issue is particularly evident when using low-power, single-phase motors.

Microcystin‐LR Triggers Renal Tubular Ferroptosis Through Epigenetic Repression of GPX4: Implications for Environmental Nephrotoxicity

open access: yesAdvanced Science, EarlyView.
MC‐LR stabilizes DNMT1/3a by blocking their ubiquitin‐mediated degradation, leading to Gpx4 promoter hypermethylation and E2F4/NCoR‐associated transcriptional repression, which drives renal tubular ferroptosis in mice. Pharmacological inhibition of DNA methylation (SGI‐1027) or ferroptosis (Fer‐1) disrupts this DNMT‐GPX4 axis, thereby alleviating MC‐LR‐

Insect I‐Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates

open access: yesAdvanced Science, EarlyView.
Upon rice viral infection, the insect vector activates the Toll–MyD88–Dorsal signaling cascade, inducing i‐type lysozyme (Lyz‐I1) expression. Lyz‐I1 functions as an antiviral protease through its conserved catalytic dyad Glu/Asp (E/D), mediating cleavage of viral proteins at specific Lys (K) residues.

Micro Biomimetic Eyeball for Humanoid Robots: A Visual System with High‐Density Functional Integration Based on an Origami Mechanism

open access: yesAdvanced Science, EarlyView.
A biomimetic eyeball system (BES) based on a 3‐DOF miniature origami mechanism, which addresses the inherent issues of large size and weight in traditional electromechanical BESs is presented. Moreover, it maintains a level of visual functionality comparable to that of the human eye, including capabilities such as rapid scanning, target recognition ...
