Structural basis for size-selective perception of chitin in plants

Plants detect microbes through pattern recognition receptors that perceive conserved microbial surface motifs known as microbe-associated molecular patterns (MAMPs). Lysin motif (LysM) receptors recognize and mediate downstream responses to chitinous MAMPs. In this study, we eluc...

Tuning Second-Sphere Amine Basicity to Modulate Hydride Intermediates and Selectivity in Molecular Manganese Bipyridine CO2 Electroreduction

Abstract Manganese bipyridine tricarbonyl complexes represent a prominent class of molecular electrocatalysts for efficient and selective CO2-to-CO conversion. Recent efforts have sought to redirect product selectivity toward HCOOH by incorporating second-sphere amine proton rela...

Responsible agrivoltaics in temperate Europe: Making systems work for plants, people, and climate

Societal Impact Statement Agrivoltaics, the co‐location of solar panels and crops, is increasingly promoted to expand renewable energy without compromising agricultural areas. However, systems that are poorly designed impact productivity, landscape, and ecology, and face public c...

Compassionate mid-level educational leadership in higher education

Purpose Mid-level educational leaders in universities are responsible for educational quality yet lack formal managerial authority. This study examines how they exercise compassionate leadership while re-sponding to competing organisational responsibilities. Design/methodology/ap...

Multiple strategies and cues define baleen whale migration

Migration is a do-or-die life-history strategy, yet factors shaping it remain poorly studied in many marine taxa, as direct observations are difficult. Building on animal migration theory, we used satellite tracking data from 21 southern right whales tagged in Aotearoa New Zealan...

Community composition drives metabolic competition and Staphylococcus aureus colonization resistance in synthetic nasal communities

Abstract The human nasal microbiome is a low-diversity ecosystem whose assembly principles and mechanisms of colonization resistance remain poorly understood. Staphylococcus aureus is a member of the nasal microbiome of some individuals with variable abundance. We hypothesized th...

“There’s not much you can do. You put up with it and bottle it up and take more drugs”: how women who use drugs navigate, negotiate, and resist gendered violence

Women who use drugs are disproportionately subjected to gendered violence, often normalized and invisible, that shapes their everyday lives in street-based drug environments and their use of harm reduction services. While research has documented this, more attention is needed to...

Development and evaluation of biopolymer–fly ash amended sand for improved water holding capacity, abrasion resistance, and plant growth in desert ecosystem

Desert sand, although mineral-rich, is unsuitable for agriculture due to its low water holding capacity and weak particle cohesion. In this study, a sustainable sand amendment approach was developed using Fly ash (FA) in combination with biopolymers, such as Guar gum (GG), Xantha...

Genomic prediction of single cross families of perennial ryegrass under two nitrogen managements

Abstract The performance of a single cross is determined by the additive effects of the parents and their interactions, which can be estimated through general combining ability (GCA) and specific combining ability (SCA). With genome‐wide marker information, it is possible to pred...

RNA Organelles in DNA‐Based Artificial Cells Provide Spatial Aptamer Functions and Enhanced Signal Processing

ABSTRACT Naturally occurring biomolecular condensates orchestrate key cellular processes by creating spatially distinct reaction environments, yet engineering synthetic condensates that combine structural programmability with spatioselectively encoded function remains challenging...

Hypoxia and right ventricular dysfunction in patients with acute pulmonary embolism

In patients with acute pulmonary embolism (PE), hypoxia may increase pulmonary vascular resistance and worsen right ventricular dysfunction (RVD), which is a key prognostic factor. However, associations between hypoxia, RVD and clinical outcomes have not been well described. To d...

Self-Replicating Neural Cellular Automata: Quantifying Emergent Phenotypic and Genotypic Diversity in an Open-Ended Substrate

We study an in silico substrate in which every pixel of a two-channel cellular-automata grid carries a tiny neural network (an agent) that senses its Moore neighbourhood. A cell persists only by self-replication: a living neighbour is cloned, and its weights are mutated by a unif...

Assessing the Correct Electrochemical Surface Area of Gold Electrocatalysts by Copper Underpotential Deposition

Abstract Knowing the electrochemical surface area (ECSA) is crucial to fully understand an electrocatalytic system and correctly contextualize the behavior of a catalyst. We show that the surface oxidation method poses several problems for the ECSA determination, while the copper...

Advancing mathematics research with AI-driven formal proof search

Large language models (LLMs) increasingly excel at mathematics tasks, but their unreliability limits their utility in mathematics research. A mitigation is to use LLMs to generate formal proofs in languages such as Lean, in which the compiler verifies every proof step. We present...

Urine Ammonium During Normothermic Machine Perfusion as a Marker of Donor Kidney Function

Background. Optimizing graft selection remains a central priority, and normothermic machine perfusion (NMP) provides a potential platform for pretransplant organ assessment. Kidney ammonium excretion quantifies proximal tubular and interstitial function. This study investigated u...

Profiling peripheral immune cells in Parkinson's disease: A scoping review

Parkinson's disease (PD) is increasingly recognized as a multi-system disorder with immune dysregulation extending beyond the central nervous system. Although numerous studies have examined peripheral immune alterations in people with PD, findings remain heterogeneous and difficu...

Balanced Animal Nutrition for Better Feeds, Healthy Animals, Safe Food, and a Healthy Planet: A One Health Perspective—An Invited Review

Livestock production is increasingly expected to deliver not only higher output, but also better animal health and welfare, safer and more nutritious food, viable livelihoods, and lower environmental pressure. This invited review examines balanced animal nutrition within a One He...

Staphylococcus aureus PSMα1 amyloid structure is modulated by buffer and salt

Amyloid fibrils share a characteristic cross-β structure yet often display pronounced polymorphism, where a single protein or peptide sequence can adopt multiple distinct fibrillar architectures. Environmental factors such as buffer composition, ionic strength, and pH strongly in...

Lifts of endomorphisms of Weyl algebras modulo p2

Let φ denote a k -algebra endomorphism of the n -th Weyl algebra A n ( k ) over a perfect field k of positive characteristic p . We prove that φ can be lifted to an endomorphism of the Weyl algebra A n ( W 2 ( k ) ) over the Witt vectors W 2 ( k ) of length two over k if and only...
