Unconventional Biexciton Dynamics in Superradiant Perovskite Quantum Dots Driven by Many‐Body Correlations

ABSTRACT Excitons and biexcitons emission traits, for example, quantum yield, lifetime, and coherence, govern device performance metrics including brightness, optical gain thresholds, and the efficiency of single‐ and entangled‐photon generation. Biexcitons are conventionally und...

Can Organic Amendments Override Environmental Filtering of Soil Microbiomes? Evidence From 20 Years Old Agricultural Field Trials in Contrasting Tropical Sites

ABSTRACT Soil microbial communities underpin ecosystem functions critical for sustainable agriculture, yet our understanding of how long‐term management of tropical agroecosystems shapes these communities remains limited. This is particularly the case in sub‐Saharan Africa where...

Lysine Oxidation by LOXL2 in Single Strands Versus Triple Helices: Implications for Collagen‐Related Diseases

ABSTRACT Collagen cross‐linking is essential for the structural integrity of the extracellular matrix. In several pathological conditions, the triple‐helical core of collagen is disrupted, and proline‐rich single strands occur. Lysyl oxidases (LOXs), enzymes that initiate cross‐l...

Haplotype-phased assemblies of the two poplar rust fungi species: Melampsora larici-populina and Melampsora allii-populina

Dikaryotic rust fungi maintain two distinct haploid nuclei for most of their life cycle, making their large, repeat-rich genomes difficult to assemble and phase. Here we present haplotype-phased, near chromosome-scale genome assemblies for the poplar rust pathogens Melampsora lar...

GIANT LEAPS Policy Brief 4 Consumer insights to encourage the dietary shift

This policy paper, intiated by the Horizon Europe GIANT LEAPS project (grant no. 101059632), aims to provide a perspective on consumer acceptance in relation to a dietary shift from animal-based to alternative proteins. In recent years, many meat, milk, cheese, or yogurt alternat...

Interpretable machine learning for urban heat mitigation: Attribution and weighting of multi-scale drivers

Abstract Strategies to mitigate urban heat are often analysed using complex models. Here, we propose a machine learning method for highly interpretable emulators of such models to efficiently inform actionable levers to mitigate urban heat. We first pre-classify parameters accord...

Disentangling the drivers of heterogeneity in SARS-CoV-2 transmission from data on viral load and daily contact rates

Abstract SARS-CoV-2 transmission is highly overdispersed, with a minority of individuals responsible for the majority of transmission, though the drivers of this heterogeneity are unclear. Here, we assess the contribution of variation in viral load and daily contact rates to this...

SCENE: A Framework for Single-cell Gene Co-expression Network Analysis Across Cell Types and Conditions

Single-cell RNA sequencing (scRNA-seq) enables detailed characterization of gene expression across diverse cell types and conditions. While most analyses focus on differential expression and cell-type abundance, changes in gene–gene interaction patterns—key drivers of cellular fu...

Global Circulation of Martian Ionospheric Currents Revealed by Magnetometer Data

Abstract In the dynamo region of the Martian ionosphere, a large‐scale current is generated by charge separation: ions collide with neutrals while electrons preferentially gyrate around local magnetic field lines. Using MAVEN magnetometer data and a physics‐informed neural networ...

Multiband condensate of magnons in two dimensions

Wavelike bosonic particles can accumulate in a single mode characterized by a particular wavelength, and such condensates are at the heart of phenomena such as superconductivity and superfluidity where usually a single complex number describes their state. If there are several fl...

Towards resilient forest establishment in Europe: functional traits, genetic diversity and multifunctional design

Abstract Forest restoration and afforestation across Europe are accelerating, yet the decision-making processes governing forest establishment remain unevenly examined, especially from a biodiversity perspective. Considering this and the global environmental changes of climate sh...

Agrivoltaics can reduce political polarization and local opposition to solar energy on land

Abstract As solar energy deployment on land intensifies, political polarization and local opposition increasingly challenge its social acceptance. We propose that agrivoltaics – a dual land-use technology that combines solar power generation with agricultural production – can hel...

Residual distribution predictive systems

Conformal predictive systems are sets of predictive distributions with theoretical out-of-sample calibration guarantees. The calibration guarantees are typically that the set contains a forecast distribution whose prediction intervals exhibit the correct marginal coverage at all...

A two-tier SHM framework for nonlinear identification of friction pendulum isolators in base-isolated buildings

This paper presents a structural health monitoring (SHM)–oriented framework for the nonlinear identification of friction pendulum isolators in a real base isolated school building. Based on a parametric investigation carried out for this study, which identifies the high-speed fri...

Non-Gaussian Noise Magnetometry Using Local Spin Qubits

Atomic scale qubits, as may be realized in nitrogen vacancy (NV) centers in diamond, offer the opportunity to study magnetic field noise with nanometer scale spatial resolution. Using these spin qubits, one can learn a great deal about the magnetic-field noise correlations, and c...

Post-heatwave immune challenge reshapes selection on heatwave responses

Abstract Climate change increases the frequency and intensity of heatwaves, yet predicting selection on heatwave-induced phenotypic responses is difficult because their fitness consequences may depend on subsequent environmental conditions. We experimentally tested how variation...

Attitudes towards carbon taxation in the EU: messenger effects vs. content effects

Abstract This paper investigates how European Union institutional sources influence public support for carbon taxes through messenger effects. Our framework predicts that support decreases with higher tax rates, an effect moderated by respondents’ associations with the source, na...

Determinants of highly pathogenic avian influenza spread during bird migration

Abstract Migratory waterfowl are central to the global spread of the Goose/Guangdong lineage of H5 highly pathogenic avian influenza (HPAI), yet the parameters and processes shaping their role remain poorly understood, with evidence scattered across studies focused on narrow sets...

Beyond benchmarking: an expert-guided consensus approach to spatially aware clustering

Spatial omics technologies have revolutionized the study of tissue architecture and cellular heterogeneity by integrating molecular profiles with spatial localization. In spatially resolved transcriptomics, delineating higher-order anatomical structures is critical for understand...

Importance of hydrated aerosol particles for aerosol–fog relationships in the Italian Po Valley

Abstract. Air pollution and fog are closely connected, influencing both visibility and human health. As relative humidity rises, aerosol particles absorb water and grow hygroscopically, potentially activating into fog droplets when supersaturation is reached. Distinguishing betwe...
