Disruptions in outer membrane-peptidoglycan interactions enhance bile salt resistance in O-antigen-producing E. coli

mBio
Bile salts (BS) are antimicrobials that disrupt bacterial cell membranes and induce oxidative stress. The gut bacterium Escherichia coli is naturally resistant to BS, including the model strain K12 MG1655 that produces a lipopolysaccharide (LPS) without ...

Covalent Attachment of Quaternary Ammonium Group to Geopolymer Surface With Silane Coupling Agent to Enable Simultaneous Adsorption of Cations and Anions

Advanced Materials Interfaces, EarlyView.
Modification of geopolymer surface with a silane coupling agent containing quaternary ammonium group enables the development of dual‐functioning ion exchanger for both cations and anions. In the present study, the performance of this material was demonstrated for the uptake of ammonium and nitrate from water.

An N4-like Caulobacter phage requires host smooth lipopolysaccharide biosynthesis for infection

Journal of Bacteriology
Caulobacter species are Alphaproteobacteria that commonly inhabit plant-associated and aquatic microbial communities. Although Caulobacter is widespread and has long served as a model for the study of bacterial cell biology, our understanding of viruses ...

A two-step screen identifies a small molecule that disrupts membrane voltage and is effective against growing and persister gram-negative bacteria

Microbiology Spectrum
New antibiotics effective against gram-negative bacteria are difficult to discover because many small molecules are excluded by the cell envelope. There is a growing consensus that the proton motive force (PMF) represents a key target for the development

An Imaging‐Guided, Patient‐Specific Guiding Aid (RWNGuide) for Safe and Reproducible Inner Ear Drug Delivery

Advanced Materials Technologies, EarlyView.
A patient‐specific, imaging‐guided aid enables precise and reproducible drug delivery to the inner ear. By guiding therapeutic agents directly to the round window niche, this approach reduces variability in drug localization, improves delivery safety, and addresses a critical bottleneck in inner ear therapy, offering a scalable strategy for precision ...

A multilayered cell envelope of a member of the Chloroflexota offers an anchoring platform for the archaellum

Frontiers in Microbiology
In a previous study, we discovered that Litorilinea aerophila, a member of the bacterial phylum Chloroflexota, had acquired a bona fide archaellum gene cluster through horizontal gene transfer from Archaea, a surprising finding given that the archaellum ...

Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

Advanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

Intelligent Maintenance Review for Robots: Multimodal Information, Deep Diagnosis and Embodied Artificial Intelligence

Advanced Robotics Research, EarlyView.
This review maps the methods to monitor robots’ health by fusing vibration, sound, control signals, vision, force, and oil information with artificial intelligence. It identifies deep learning, transfer learning, digital twins, and physics‐informed models as key methodological pathways enabling earlier diagnosis, safer human–robot collaboration, and ...
