DNA Polymerase IV dinB Favors the Adaptive Fitness of mcr‐carrying Bacteria Through a Negative Feedback Regulatory Mechanism

open access: yesAdvanced Science, Volume 12, Issue 12, March 27, 2025.
This work demonstrates that DNA polymerase IV dinB favors the adaptive fitness of mcr‐carrying bacteria via a negative feedback regulatory mechanism. Specifically, the elevation of ROS production by intact mcr activates dinB, which in turn represses the mcr expression, maintaining a balance between colistin resistance and bacterial fitness.

Design Principles From Natural Olfaction for Electronic Noses

open access: yesAdvanced Science, Volume 12, Issue 12, March 27, 2025.
Unlocking “universal smell” requires integrating key principles of natural olfactory systems: modulation of gas transport, utilization of non‐selective sensing elements, chemical filters akin to the biological mucus layer to separate compounds, refined context‐specific signal integration, and more.

Advances in Fecal Microbiota Transplantation for Gut Dysbiosis‐Related Diseases

open access: yesAdvanced Science, Volume 12, Issue 13, April 3, 2025.
This article reviews the use of fecal microbiota transplantation (FMT) to treat intestinal diseases like recurrent Clostridioides difficile infection (rCDI), inflammatory bowel disease (IBD), and irritable bowel syndrome (IBS). It discusses FMT's efficacy, influencing factors such as donor selection, recipient characteristics, and treatment protocols ...

Improving CO Oxidation Catalysis Over High Entropy Spinels by Increasing Disorder

open access: yesAdvanced Science, Volume 12, Issue 15, April 17, 2025.
This work demonstrates that changing configurational disorder can significantly improve catalytic activity and stability. A series of high entropy spinel oxides (HESOs) are synthesized using air‐stable molecular precursors to build crystal lattices atom‐by‐atom. Spinel oxide powders are extensively characterized with a variety of advanced methods (i.e.

Ru Single Atoms Anchored on Oxygen‐Vacancy‐Rich ZrO2‐x/C for Synergistically Enhanced Hydrogen Oxidation

open access: yesAdvanced Science, Volume 12, Issue 18, May 15, 2025.
The alkaline HOR performance of ruthenium single atoms electrocatalysts are explored to investigate the catalytic action of ruthenium. Experimental characterization and theoretical simulations further demonstrate that low‐coordination Ru atoms modulate the electronic structure of the reaction site, optimizing hydrogen bonding energy and hydroxyl ...
