A Resistive Soft Robotic Exosuit for Dynamic Body Loading in Hypogravity

Advanced 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 ...

Multi‐Habitat Landscape Promotes Microbial Diversity: Insights from the Traditional Agricultural Heritage and the Global Trend

Advanced Science, EarlyView.
The 2500‐year‐old Mulberry‐dyke and Fish‐pond agricultural heritage system reveals how interconnected habitats foster microbial diversity. Multi‐habitat landscapes enhance microbial diversity through cross‐habitat dispersal and adaptive trait convergence. Globally, regions with diverse habitats support a greater diversity of soil microbiomes.

Depth‐Dependence Changes in Soil Stoichiometry in China's Croplands Over the Past Four Decades

Advanced Science, EarlyView.
This study reveals depth‐dependent changes in soil C:N:P ratios across Chinese croplands over four decades. Changes in stoichiometry vary markedly between topsoil and subsoil, with initial soil C:N:P ratios playing a key role in determining their trajectories.

Bioinspired Twisted Artificial Muscles with Enhanced Performance for Underwater Applications

Advanced Science, EarlyView.
A climbing plant‐inspired twisted artificial muscle (TAM) with a braided configuration and seal‐inspired thermal insulation enables high‐performance underwater actuation. Enhanced deformation, reduced heat dissipation, and rapid motion are validated through a bionic ray that exhibits straight and turning motions.
