Direct evidence of apex–hypha interactions during vegetative growth of fungal thallus via comprehensive network and trajectory extraction

Abstract The mycelium of a filamentous fungus is a growing, branching network of numerous entangled hyphae exhibiting polarized apical growth. Expansion occurs during the vegetative phase from a single ascospore, driven by the need to explore and occupy surrounding space—limiting...

Co‐Ligand‐Induced Electronic Modulation Controls Substrate Adsorption and Selectivity in Biomass Electrooxidation

ABSTRACT The electrooxidation of 5‐hydroxymethylfurfural (HMF) to 2,5‐furandicarboxylic acid (FDCA) is often limited by competitive adsorption between HMF and surface‐bound hydroxyl species (OH ads ), which governs both activity and selectivity, yet independent control over these...

Orographic impacts of Réunion Island and Madagascar on heavy rainfall during Tropical Cyclone Batsirai (2022)

Abstract. During the passage of tropical cyclone (TC) Batsirai (2022), the mountainous regions of Réunion Island and the eastern part of Madagascar experienced devastating floods. TC Batsirai passed north of Réunion Island (minimum distance of ~210 km) before making landfall alon...

2D Covalent Organic Frameworks as Robust n‐Type Organic Mixed Ionic‐Electronic Conductors for Electrochemical Transistors

ABSTRACT Organic mixed ionic‐electronic conductors (OMIECs) with exclusive electrochemical modulation and coupling between ions and electrons have exhibited intriguing efficiencies in bioelectronics, logic circuits, and wearable devices. However, OMIECs are typically linear polym...

Matrix‐Activated Aptamer Sensors for Human Serum Analysis

ABSTRACT Owing to their ease of operation, solution‐phase fluorescent sensors hold a crucial position among aptamer‐based detection tools. However, their performance is regularly compromised when exposed to increasing levels of blood fluids, such as human serum, which limits thei...

Stochastic Optimal Control for Systems with Drifts of Bounded Variation: A Maximum Principle Approach

Abstract. We study a stochastic control problem for nonlinear systems governed by stochastic differential equations (SDEs) with irregular drift. The drift coefficient is assumed to decompose as [Formula: see text], where [Formula: see text] is bounded and Borel measurable, [Formu...

Adsorption of Cobalt onto Microplastics in Riverine Mesocosms: Influence of Biofilm Development

The plastisphere critically modulates interactions among microplastics (MPs), biofilms, and trace metals under environmentally realistic conditions, governing the interfacial reactivity of plastisphere-coated microplastics. Here, we investigated cobalt (Co) adsorption onto large...

Robust inference and correlates from genetic associations with personality

Personality traits describe stable differences in how people think, feel and behave, and how they interact with and experience their social and physical environments1,2. Many questions remain unanswered about associations between DNA and personality traits, such as their robustne...

Cost-utility study of cognitive-behavioural management of auditory hallucinations in schizophrenia: a study protocol

Abstract Background Auditory verbal hallucinations (AVHs) affect 60–80% of patients with schizophrenia, causing significant distress and functional impairment. Although cognitive-behavioural therapy (CBT) has been shown to reduce AVH-related distress and relapse risk, its use rem...

DNA methylation either antagonizes or promotes Polycomb recruitment at transposable elements in Arabidopsis

Abstract Transposable elements (TEs) are usually silenced by DNA methylation and H3K9me2, but in the absence of DNA methylation they can instead acquire the Polycomb-associated mark H3K27me3. Here, we initially set out to test whether DNA methylation and H3K27me3 compete during T...

Integrated experimental and modeling study of air psychrometry and velocity effects on cooling pad performance

This study presents a combined experimental and modeling investigation of cellulose-based evaporative cooling pads, focusing on the synergistic effects of inlet air psychrometric conditions and air velocity on cooling performance. Unlike conventional studies that examine temperat...

Accurate MAG reconstruction from a complex soil microbiome through combined short- and HiFi long-reads metagenomics

Abstract Background Advances in high-fidelity long-read (HiFi-LR) sequencing technologies have opened new opportunities to explore the microbial genomic diversity of complex environments, such as soils. While short-read (SR) sequencing has enabled broad insights at the gene level...

Increased maximum carbon release offsets half of the growth trend in annual land carbon sink

The terrestrial carbon sink has strengthened in recent decades through enhanced maximum CO2 uptake (MCU) and a longer carbon uptake period (CUP), whereas maximum CO2 release (MCR) remains less quantified. Using atmospheric inversion estimates and 16 terrestrial biosphere models,...

The interplay of time pressure and AI assistance reveals moral responsibility recalibration in high-stakes decisions

As artificial intelligence (AI) systems are increasingly integrated into high-stakes decision-making environments, understanding how humans interact with these systems under time pressure is critical for ethical and effective human-AI teaming. While previous research has shown th...

Combined effects of difenoconazole and salinity stress on growth, photosynthetic pigments, and oxidative responses in tomato (Solanum lycopersicum L.)

Environmental contamination by pesticides and salts is a growing agricultural issue, especially in arid and semi-arid regions. Difenoconazole (DIF), a commonly used fungicide, and sodium chloride (NaCl), a widespread salinity stressor, often coexist in soil and water, yet their c...

Zoological biobanks as a resource for microplastic analysis: a Py-GC-MS/MS case study on sea cucumbers

Microplastics have spread through every ecosystem studied. Yet, documenting their spatiotemporal distribution remains challenging, particularly in marine environments where sampling is costly and difficult. Archived specimens in zoological biobanks offer an underused resource for...

Regulation-aware combinatorial optimization of energy community formation under geographic proximity constraints

Renewable Energy Communities (RECs) enable collective self-consumption by allowing geographically proximate households to share locally generated renewable energy. While most existing studies optimize the operation of a pre-defined community, the prior problem of how to partition...

Septin architecture dictates size-dependent diffusion barriers on biomimetic membranes

Abstract Septins are cytoskeletal filaments bound to the inner leaflet of the plasma membrane, essential for cell division. They are involved in the formation of diffusion barriers for membrane-bound components. Whether septins directly function as barriers or as part of a broade...

Molecular basis of nick ligation in the nucleosome by DNA Ligase IIIα

Eukaryotic genomic DNA is packaged into chromatin through a fundamental repeating unit known as the nucleosome core particle. Within this chromatin context, genomic DNA is constantly exposed to endogenous and exogenous stress that result in the formation of DNA damage, which must...
