Ultrathin 2D In2O3 Nanosheets Confining Cu Single Atoms Synergized With Oxygen Vacancies for High Selectivity of Photocatalytic Reduction of CO2 to CO

Advanced Science, EarlyView.
In this work, we constructed an ultrathin two‐dimensional (2D) In2O3 nanosheet (In2O3‐Ns) structure based on oxygen vacancies (OV)‐rich defects and low crystallinity to anchor Cu single atoms (Cu SAs) and synthesized Cu/In2O3‐Ns photocatalysts. ABSTRACT In this work, we constructed an ultrathin two‐dimensional (2D) In2O3 nanosheet (In2O3‐Ns) structure ...

Oligosaccharides With Defined Glycosidic Bonds Shape Gut Microbial Succession and Metabolism Via Bond‐Specific Microbial Responders

Advanced Science, EarlyView.
Oligosaccharides with defined glycosidic bonds drive divergent gut microbial succession and shape unique metabolic profiles. Absolute time‐series profiling with Bayesian generalized Lotka–Volterra modeling identifies bond‐specific microbial responders, while monoculture validation and metaproteomics reveal linkage‐matched transport and cleavage modules.

YTHDC1 Orchestrates Glucose and Glutamate Rewiring to Overcome Lethal Metabolic Stress in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
Lai et al. find that m6A reader YTHDC1 is specifically overexpressed in triple‐negative breast cancer (TNBC) and orchestrates glucose and glutamine metabolism in an m6A‐dependent manner to confer robust adaptability to lethal metabolic stress. Leveraging YTHDC1 knockdown‐induced metabolic vulnerability, an ATF4 mRNA‐targeted nanotherapy is developed to
