Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

open access: yesAdvanced Theory and Simulations, EarlyView.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design

Alistipes senegalensis is Critically Involved in Gut Barrier Repair Mediated by Panax Ginseng Neutral Polysaccharides in Aged Mice

open access: yesAdvanced Science, EarlyView.
An integral functional axis through which GPN and functional metabolites of Alistipes senegalensis can hydrolyze tryptophan into indoles. Furthermore, the Alistipes senegalensis‐indole‐AhR pathway is found to be associated with increased expression of tight junction‐associated proteins and activation of gut stem cells.

Crystalline‐Amorphous Heterostructure: A Novel Configuration for Silver Nanoclusters

open access: yesAdvanced Science, EarlyView.
This study presents a spontaneously formed amorphous‐crystalline heterostructure composite composed of atomically precise carboranylthiolate‐protected silver NCs, demonstrating not only a unique co‐assembly of distinct metal NCs at the macroscopic level but also promising potential applications of metal cluster‐based materials.

Bacteria Optimize Tumble Bias to Strategically Navigate Surface Constraints

open access: yesAdvanced Science, EarlyView.
The study investigates how Escherichia coli optimizes tumble bias (TB) to navigate surface constraints effectively. Using single‐cell tracking and modeling, it reveals that bacterial surface residence time decreases with increasing TB, stabilizing near the wild‐type mean TB (≈0.25), where surface diffusivity peaks.
