UV‐Triggered Cascading Degradation of Silicone Elastomer via Self‐Fluoride Amplification

Advanced Science, EarlyView.
UV‐triggered degradable materials offer proficient control of functional lifetime, while having issues with trigger efficiency. This work enhances the UV‐triggered degradation mechanism of silicone elastomer by introducing the UV‐initiated synergetic fluoride self‐amplification. The silicone composite shows excellent mechanical properties and on‐demand

Bacteria Optimize Tumble Bias to Strategically Navigate Surface Constraints

Advanced 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.

Zoborg: On‐Demand Climbing Control for Cyborg Beetles

Advanced Science, EarlyView.
A novel on‐demand climbing protocol enables Zoborg (a cyborg beetle from the living Zophobas morio) to seamlessly transition from horizontal floors to vertical walls. Multiple unrestrained mechanosensors allow wall sensing while electrical stimulation of the elytron initiates climbing. Leveraging the agile locomotion and exceptional adaptability of the
