Ultra‐Low Intensity Continuous Wave Laser Ablation Propulsion With Graphene‐Engineered Wood
Graphene delignified wood converts continuous wave laser energy into thrust. Laser propulsion experiments in vacuum reveal the lowest laser ablation threshold intensities and the greatest density‐normalized specific impulse in literature. The results highlight graphene delignified wood as a potential efficient, sustainable, strong, and lightweight ...

An origami worm‐inspired robot achieves multimodal locomotion in confined pipelines through mechatronic integration that embeds actuation, control, and communication within each origami module. Large, reversible configuration and dimensional changes enable 25 gaits synthesized by a unified framework across peristaltic, inchworm, and wheel‐rolling modes

Floral meristem (FM) activity is crucial for the initiation of floral organs. In this study, SE represses IPT7 expression and cytokinin signaling via both the miR171c‐5p–KNAT2 and miR164c–CUC1/2–KNAT2 regulatory modules, thereby repressing FM activity. In contrast, STM induces both KNAT2 and IPT7 expression.

Electrohydraulic Folding Ring Actuators for Radially Contracting Applications
This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

Enhancing Biogenic Formic Acid Production in the Modified OxFA Process by Acetonitrile Addition
In this study, the beneficial effect of using acetonitrile as a co‐solvent in the modified OxFA process is shown, outperforming methanol, demonstrating improved reaction kinetics combined with high selectivity for the HPA‐2 (H5PV2Mo10O40) catalyzed oxidation of xylose to FA.

A sulfated polysaccharide (SCP) from Cyclocarya paliurus alleviates ulcerative colitis by reshaping the gut microbiome. This remodeled microbiota orchestrates the upregulation of the host‐derived lipid 12‐HEPE, which directly inhibits the TLR4/NF‐κB pathway to suppress inflammation.
