Wildfire exposure and political participation in Africa

Abstract Civic engagement can shape collective responses to climate change. However, evidence on how climate-related disasters affect political participation in Africa remains limited. Combining Global Fire Atlas records with Afrobarometer surveys of more than 100,000 people in 3...

Revealing the Impacts of Molecular Rigidity and Orientation on Interfacial Contact in Efficient Perovskite Solar Cell

Self-assembled monolayers (SAMs) are widely employed as hole transport layers in inverted perovskite solar cells (PSCs), but suffer from insufficient surface coverage and difficulties in spin-coating a perovskite film on top. Herein, we design and synthesize two novel corannulene...

B3GNT3 defines a spatially restricted dysfunctional T-cell niche and predicts immunotherapeutic outcomes in lung adenocarcinoma

Abstract Background Immunotherapy response in lung adenocarcinoma (LUAD) remains highly heterogeneous, underscoring the need for biologically informative markers of tumor immune dysregulation. B3GNT3, a glycosyltransferase implicated in several malignancies, is poorly characteriz...

Synthesis and Phase Evolution of Ultra-High Temperature MC-Type Carbides (M = Hf, Ta, Nb, Zr, Ti) via a Molecular Precursor Approach

In the present work, a series of single-source precursors were prepared via a one-pot synthesis strategy using transition metal chlorides, acetylacetone, and hydroquinone as raw materials. The molecular structure, cross-linking behavior, and polymer-to-ceramic transformation of t...

Prediction of Failure in Lithium‐Rich Cathode Half‐Cells Using Early‐Cycle Data

ABSTRACT Lithium‐ion batteries have attracted sustained attention because of their wide applications in energy storage systems. In laboratory research and development, the electrochemical performance of electrode materials is commonly evaluated using half‐cell configurations. How...

Classification of magnetism and altermagnetism in quasicrystals

Altermagnetism (AM), an unconventional magnetic phase characterized by zero net magnetism protected by symmetry(s) other than parity-time ( \({\mathcal{P}}{\mathcal{T}}\) ) and a resulting spin-split band, has been studied exclusively in crystalline materials. Here, we extend the...

Genetic mutations driving ciprofloxacin resistance in laboratory-evolved Salmonella Typhimurium

ABSTRACT Ciprofloxacin resistance in Salmonella Typhimurium is a significant public health concern, and the mechanisms by which the resistance evolves are poorly defined. Here, by serial passaging under antibiotic selection, we isolated ciprofloxacin-resistant S . Typhimurium mut...

PTTG1-driven self-amplifying loop with SP1 and ENO1 promotes IRF4-mediated myeloma progression and bone destruction

Abstract Multiple myeloma (MM) is a neoplastic disorder of plasma cells within the hematopoietic system and is characterized by osteolytic lesions. Despite significant advances, the molecular underpinnings of myeloma and its associated bone pathologies remain elusive, and there i...

Temporal Evolution and Vertical Distribution of Size-Resolved Aerosol Composition and Mixing State within the Boundary Layer Using an Unmanned Aerial Vehicle

Abstract Characteristics of individual particles and aerosol mixing state strongly influence atmospheric chemistry, radiation, and cloud formation yet remain poorly constrained. Here, we investigated the spatiotemporal evolution of size-resolved particle composition in a coastal...

Phytochemicals Modulating Receptor Tyrosine Kinase Signaling Networks in Endometriosis

Endometriosis is a chronic, estrogen-dependent inflammatory condition that is marked by the growth of lesions outside the uterus, along with angiogenesis, fibrosis, immune dysregulation, and pain sensitization. There is now growing evidence that receptor tyrosine kinase (RTK) sig...

Do trade barriers drive innovation? Micro-level evidence from anti-dumping and countervailing measures on R&D in Chinese solar PV firms

As international trade protectionism continues to grow and the renewable energy sector evolves rapidly, anti-dumping and countervailing measures (ADCV) pose a significant challenge to Chinese photovoltaic (PV) firms. Faced with the challenges of ADCV, it remains crucial to explor...

Sustainability-Driven Seismic Resilience Assessment and Multiobjective Optimization of DSM-Retrofitted RC Bridges on Liquefiable Ground

Abstract Sustainability and seismic resilience are increasingly essential for infrastructure systems, prompted by the demand to endure more frequent extreme events while minimizing environmental impacts. This paper presents a sustainability-driven, multiobjective framework for as...

Discovery of Stereoselective UrCYP71AU Oxidases Catalyzing the Final Biosynthetic Step of Rhynchophylline and Mechanistic Insights into 7R and 7S Spiroindole Skeleton Formation

Abstract Rhynchophylline (RHY) is a spiroindole alkaloid that acts on the cardiovascular and central nervous systems. Based on the distribution patterns of 7R and 7S spiroindole alkaloids in U. rhynchophylla, we hypothesize the existence of hirsutine oxidase responsible for 7R an...

How testosterone administration affects social rank perceptions: A double-blind, placebo-controlled study

Navigating social hierarchies is fundamental to human survival and reproductive success, relying heavily on the accurate perception of social rank. However, the neuroendocrine mechanisms underlying this perception remain largely uncharted. Given testosterone’s established role in...

Organic Matter Sources and Black Carbon Fractions Shape Mercury Partitioning in Intertidal Sediments of the Yangtze Estuary

Estuarine intertidal sediments are important sinks for riverine mercury (Hg), yet the effects of organic matter sources and BC fractions on Hg partitioning are still poorly understood. We analyzed sediments from reed-covered and unvegetated flats in the Yangtze Estuary for total...

Conceptions of GenAI-assisted learning among university students with different levels of self-perceived AI literacy: a drawing-based content analysis and epistemic network analysis

As generative artificial intelligence (GenAI) becomes increasingly prevalent in higher education, understanding how students conceptualize its role in learning has become an important issue in AI education research. Existing studies have examined learning outcomes, usage intentio...

Sustained algal-bacterial interactions promote accumulation of recalcitrant particulate carbon with accelerated radiocarbon aging signatures

Algal-bacterial interactions regulate the production and fate of marine particulate organic carbon (POC), yet their capacity to generate long-lived carbon sinks remains unclear. Using a two-year, nutrient-self-sustaining co-culture of Synechococcus and its mutualistic microbiota,...

Plasmonic-enhanced lanthanide nanotransducers for mid-infrared detection

Advanced mid-infrared (MIR) detection underpins a wide range of applications from chemical sensing to thermal imaging. Conventional MIR photodetectors rely on narrow-bandgap semiconductors that typically require cryogenic cooling, whereas uncooled alternatives suffer from inheren...
