Hosts and Commensal Bacteria Synergistically Antagonize Opportunistic Pathogens at the Single‐Cell Resolution

open access: yesAdvanced Science, EarlyView.
In the tripartite‐species model, Drosophila larvae stimulate lactate production through excreting digestion enzymes. S. marcescens population senses a cue of lactate and tends to diverge into virulent and reduced virulence subclusters with remarkable heterogeneity to metabolize carbon metabolism and counter colonization resistance, giving a fitness ...

Electronic Microenvironment Regulation of Bismuth‐salophen Single‐site Catalysts for Enhanced Selectivity in CO2 Electrolysis to Formic Acid

open access: yesAdvanced Science, EarlyView.
The microenvironment modulation of Bi SSCs via electronegative group (─F/─H/─OMe) modification demonstrably suppresses the HER at high current densities, achieving a HCOOH FE of 95%. The ─F group optimizes the electronic structure of Bi, significantly enhancing CO2 adsorption and reducing the energy barrier for *OCHO intermediate formation, thereby ...

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.

A Full‐Range Proximity‐Tactile Sensor Based on Multimodal Perception Fusion for Minimally Invasive Surgical Robots

open access: yesAdvanced Science, EarlyView.
A full‐range proximity‐tactile sensing module is developed for safe operation of surgical robots, which performs multimodal fusion perception through ultrasonic sensor for long‐range proximity detection, capacitive sensor for close‐range proximity sensing, and triboelectric sensor for tactile sensing.

Fast pH‐Driven Solubilization Method of Realgar (As4S4) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes

open access: yesAdvanced Science, EarlyView.
Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.

Deciphering Cell Type Abundance in Proteomics Data Through Graph Neural Networks

open access: yesAdvanced Science, EarlyView.
GraphDEC constructs pseudo bulk reference data using a mixup strategy, then learns low dimensional representations via autoencoders to model intra and inter dataset relationships. These are processed through a multi view adaptive neighborhood aware GNN, integrating reference, target, and joint graphs.

Proton Acceleration with Relativistic Electromagnetic Shock

open access: yesAdvanced Science, EarlyView.
New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.
