Sex‐ and Time‐Resolved Physiological and Gut Ecosystem Responses to a Food‐Grade Microbiome‐Targeted Intervention in Collegiate Endurance Athletes

Advanced Science, EarlyView.
In collegiate endurance athletes, a 6‐week randomized CPYE intervention yielded time‐ and sex‐dependent shifts in field‐based cardiorespiratory, metabolic, and redox indices, accompanied by changes in gut multi‐omics profiles. An exploratory extension during intensified training generates hypotheses warranting future validation.

High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

Advanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.

An ATP‐Driven N Protein–DDX21 Molecular Switch Dynamically Controls SARS‐CoV‐2 RNA G‐Quadruplex Heterogeneity

Advanced Science, EarlyView.
An ATP‐driven molecular switch, comprising viral nucleocapsid (N) protein and host helicase DDX21, dynamically modulates SARS‐CoV‐2 RNA G‐quadruplex (G4) heterogeneity. These viral G4s feature non‐canonical ion‐dependence and act as energy‐sensitive structural checkpoints.

Aryl‐Tethered Pendant Sterically Shielded Imidazoliums for Durable Anion Exchange Membranes

Advanced Science, EarlyView.
An aryl‐tethered, sterically shielded imidazolium architecture protects cationic sites from hydroxide attack while avoiding vulnerable benzylic cation–polymer linkages. Incorporated into poly(arylimidazolium) membranes, this dual‐protection design enhances alkaline and oxidative durability and supports prolonged alkaline water electrolysis, offering a ...

Temporal Trajectories of the Tau Aggregate Interactome Reveal Stage‐Specific Vulnerabilities in Alzheimer's Disease

Advanced Science, EarlyView.
Tau populations with different aggregation states associate with distinct sets of proteins in the Alzheimer's disease brain. Proteomic discovery combined with single‐molecule analysis in neurons reveals dynamic associations involving proteostasis, metabolism and RNA biology.
