Multilevel Optical Programming of Intrinsic Vacancies in Solution‐Processed MoS2 Films for Retinomorphic Color Differentiation

Advanced Optical Materials, EarlyView.
Solution‐processed MoS2 films with intrinsic sulfur‐vacancy traps are used to integrate light sensing and memory in a simple two‐terminal pixel. Successive optical pulses program persistent, multilevel conductance states, while oxygen exposure enables rapid erasure.

Effects of Soluble Electron Shuttles on Microbial Iron Reduction and Methanogenesis

Applied and Environmental Microbiology
AbstractIn many aquatic and terrestrial ecosystems, iron (Fe) reduction by microorganisms is a key part of biogeochemical cycling and energy flux. The presence of redox active electron shuttles in the environment potentially enables a phylogenetically diverse group of microbes to use insoluble iron as a terminal electron acceptor.

Cancer‐Associated Fibroblasts Functions as Multifunctional Architects of the Tumor Stroma and Represent Emerging Therapeutic Vulnerabilities

Advanced Science, EarlyView.
ABSTRACT Cancer‐associated fibroblasts (CAFs) are the predominant stromal components within the tumor microenvironment (TME), playing multifaceted roles in cancer progression through dynamic interactions with neoplastic and immune cells. Emerging evidence has revealed remarkable heterogeneity and plasticity of CAFs, which originate from diverse ...

Farnesyltransferase Deficiency in Cardiomyocytes Initiates Senescence and Contributes to Cardiac Fibrosis

Advanced Science, EarlyView.
Lipid overload suppresses SREBF2‐mediated FNTB expression, leading to defective Lamin A maturation and nuclear envelope instability. This nuclear catastrophe triggers a pro‐fibrotic senescence program in cardiomyocytes. Notably, restoring nuclear integrity via AAV9‐based gene therapy effectively attenuates cardiac remodeling, identifying the ...
