Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

Advanced Science, EarlyView.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Long‐Term Active Rather than Passive Restoration Promotes Soil Organic Carbon Accumulation by Alleviating Microbial Nitrogen Limitation in an Extremely Degraded Alpine Grassland

Advanced Science, EarlyView.
Active restoration increases soil organic carbon stocks by reducing microbial nitrogen limitation. Nitrogen availability promotes particulate to mineral‐associated organic carbon conversion by reducing microbial carbon use efficiency. Passive restoration has no effect on soil organic carbon stocks.

Principles for Rigorous Design and Application of Synthetic Microbial Communities

Advanced Science, EarlyView.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction
