A Resistive Soft Robotic Exosuit for Dynamic Body Loading in Hypogravity

open access: yesAdvanced Science, EarlyView.
The resistive hypogravity exosuit is a lightweight wearable robotic exosuit that uses pneumatic artificial muscles to restore Earth‐like metabolic and muscular demands during locomotion in low gravity. Tested on healthy subjects in Earth and simulated Moon gravity, the suit restores energy expenditure and muscle activation without altering gait ...

A Natural Major Module Confers the Trade‐Off between Phenotypic Mean and Plasticity of Grain Chalkiness in Rice

open access: yesAdvanced Science, EarlyView.
This study reveals the genetic and molecular mechanisms controlling the general trade‐off between phenotypic mean and plasticity of grain chalkiness in rice and identifies two major external drivers (high temperature and wide grain) and a natural major module (GCP6‐MPC5) that control this trade‐off.

Mitochondrial Transplantation Augments the Reparative Capacity of Macrophages Following Myocardial Injury

open access: yesAdvanced Science, EarlyView.
Mitochondrial transplantation induces macrophage polarization toward an anti‐inflammatory M2 phenotype, enhances their reparative capacities, and facilitates mitochondrial transfer to cardiomyocytes, collectively promoting tissue repair and functional recovery post‐myocardial infarction.

An Automated Lab‐On‐A‐Chip Approach for Pollen Tube Growth Manipulation in a Controlled Chemical Environment

open access: yesAdvanced Science, EarlyView.
Here, a microfluidic‐based robotic lab‐on‐a‐chip (LoC) device is presented for automated, continuous‐flow investigation and manipulation of single pollen tube growth under precisely controlled chemical gradients. This closed‐loop system streamlines data collection and analysis while enhancing experimental precision compared to manual methods ...

Unveiling Exciton‐Plasmon Polariton Coupling Regions via Polarization‐Enhanced Optical Nanoscopy

open access: yesAdvanced Science, EarlyView.
Polarization‐enhanced single‐molecule localization microscopy, utilizing a liquid crystal variable retarder (LCVR), actively controls the on‐off intensity modulation of fluorophores. This active intensity modulation improves the localization accuracy of the point spread function (PSF), enabling high‐contrast super‐resolution imaging with significantly ...

Ultra‐High Friction and Adhesion in Hydrogel Layer Driven by Wet‐to‐Dry Transition Dynamics

open access: yesAdvanced Science, EarlyView.
This work reveals a critical wet‐to‐dry transition in polyacrylamide hydrogel layers that induces volumetric shrinkage, resulting in enhanced interfacial contact and dramatically increased friction and adhesion. Leveraging this transition enables strong, reversible gripping on diverse surfaces, offering new insights for hydrogel‐based gripping ...

Peptide Electrostatic Modulation Directs Human Neural Cell Fate

open access: yesAdvanced Science, EarlyView.
This study explores the effect of charge on the bioactivity of peptide‐based supramolecular materials. The design of a peptide library with varying charges that self‐assemble into supramolecular fibers is presented, demonstrating how the surface charge of these fibers, used as artificial extracellular matrices, influences the fate of human neural ...
