Trophic reorganization may contribute to shifts in nitrogen transformations following alleviation of saline alkaline stress

Soil salinization is a widespread form of land degradation, yet how saline-alkaline stress is linked to belowground micro-food webs and shapes nitrogen transformations remains poorly understood. Here we compare natural saline–sodic and reclaimed farmland soils in northeastern Chi...

A microbial therapy-mimicry assay shows how spatial resource dynamics control resistance escape

Abstract The evolution of therapy resistance in structured populations such as biofilms and solid tumours is shaped by emergent spatial organization, with profound consequences for evolution-based therapies. However, how treatment reshapes these patterns remains poorly understood...

Integrative structural modelling reveals the human Mic60-Mic19 subcomplex as a diffusion barrier in mitochondria

Abstract Mitochondrial crista junctions (CJs) operate as regulated gateways into the cristae microenvironment, whose protein, metabolite, and ion compositions are finely tuned for mitochondrial function. The Mic60-Mic19 complex of the mitochondrial contact site and cristae organi...

No CRAB Today! Identifying the Correlates of Individuals’ Climate-Related Abstinence Behavior (CRAB)

Abstract: Considering the ongoing climate crisis, climate-related abstinence behavior (CRAB), defined as an individual’s voluntary tendency to abstain from climate-unfriendly behavior, is pivotal – along with other approaches – to reduce CO 2 emissions. The current study assesses...

Cassini CDA observes compositional segregation of Enceladus’ ice grains from slow freezing and fragmentation of oceanic spray

Salt-rich ice particles, termed Type 3, are a major compositional group within Enceladus’ plume and Saturn’s E ring and are thought to represent frozen micrometer-sized aerosolized droplets of Enceladus’ salty subsurface ocean. Here, we present an analysis on the basis of ≈1000 m...

An Examination of the Cs 2 NaInCl 6 Luminescence: Interplay of Self‐Generated In + and Doped Sb 3+ , Er 3+ /Yb 3+ Ions

ABSTRACT This work introduces a novel explanation of the visible (Vis‐) and near‐infrared (NIR) Cs 2 NaInCl 6 luminescence based on spontaneously formed In 3+ →In + and a doping method by utilizing Er 3+ /Yb 3+ and Sb 3+ ions. A combined experimental and theoretical approach has...

Comparative fitness of reemerging St. Louis encephalitis virus in vertebrate and mosquito cells, Culex tarsalis and Culex quinquefasciatus mosquitoes, and mice

ABSTRACT The human pathogenic orthoflavivirus St. Louis encephalitis virus (SLEV) reemerged in the western United States in 2015 after more than a decade of absence and has since expanded throughout California with sustained interannual transmission. This shift from the historica...

Coherent Vibrational Wave Packet Motion in Er Cry4a Proteins Monitors the Redox State of the Flavin Chromophore

Abstract Cryptochromes are blue-light-sensitive flavoproteins that play central roles in biological function. In European robin (Erithacus rubecula) ErCry4a proteins, optical excitation of their flavin chromophore forms a long-lived radical pair through a sequence of electron-tra...

Network-based characterization of latent co-testing patterns in antimicrobial susceptibility testing

Antimicrobial resistance (AMR) surveillance depends on antimicrobial susceptibility testing, yet antibiotic panels vary by pathogen cohort, specimen, year, ward, and care setting. We term these empirically reconstructed testing architectures shadow antibiograms: structures that s...

Populism and impatience

Abstract We develop a model where highly impatient voters are more likely than others to be subject to institutional frictions in the form of binding borrowing constraints. As impatient, borrowing-constrained voters cannot move long-term policy gains to the present, they turn to...

A note on higher coherence of graphs of groups

Abstract For n ∈ N n\in\mathbb{N} , a group is called 𝑛-coherent if every subgroup of type F n \mathsf{F}_{n} is of type F n + 1 \mathsf{F}_{n+1} . For n ≥ 1 n\geq 1 , we observe that graphs of groups with 𝑛-coherent vertex groups and virtually poly-cyclic edge groups are 𝑛-coher...

Principles of Justice for a Sustainable Economy

Abstract Empirical evidence suggests that decoupling economic growth from greenhouse gases is impossible, thus requiring zero growth. What principles of distributive justice does a zero-growth economy call for? This article focuses on two distribuenda in a zero-growth economy. We...

Psychotherapy remission prediction models show limited cross-clinic generalizability in routine outpatient care

Abstract Clinical prediction models for psychotherapy outcomes have the potential to assist therapists in planning a patient’s individual treatment, but their clinical utility depends on maintaining predictive performance across settings. We assessed prediction of post-treatment...

Chiral Rh Diene NHC Complexes and Their Application in Rh-Catalyzed Cycloisomerization of Enynes

Abstract Chiral dienes and N-heterocyclic carbenes (NHC) are important ligands for transition-metal catalysis. Surprisingly, both ligand classes are rarely employed together in Rh complexes. To get more detailed insight into the interaction between NHC and diene ligand simultaneo...

SARS-CoV-2 and RSV external quality assessment on molecular detection and variant typing in European expert laboratories in 2025

ABSTRACT We herein report on the fourth SARS-CoV-2 wet-lab external quality assessment (EQA) and the second organized by the AURORAE consortium to assess the diagnostic capabilities of European expert public health laboratories. Diagnostic capabilities were investigated regarding...

Shallow Landslides Align With Atmospheric Rivers in Coastal Steeplands

Abstract Rapid, shallow landslides in coastal mountains are triggered by extreme precipitation, shaping topography and impacting human settlements. Using an inventory of >700 landslides mapped from satellite imagery (2009–2024) and an atmospheric river database (1981–2019), this...

Development of a Core Outcome Measurement Set for studies of community pharmacist-led medication reviews in older patients with multimorbidity and polypharmacy

Abstract Introduction A Core Outcome Set (COS) can harmonize outcome reporting. For medication review (MR) studies targeting older, multi-morbid patients with polypharmacy, a COS with seven outcomes is available: Health-related Quality of Life (HRQoL), pain relief, overuse, under...

Transdisciplinary and International Collaboration in Disaster Research: A Procedural Model Approach

Transdisciplinary and international collaboration has become increasingly central to disaster research, yet its organizational and institutional dynamics remain insufficiently understood. Based on insights from a four-year international research project on integrated disaster ris...

Dual antidiabetic potential of arjunglucoside I and arjunetin from Terminalia chebula via modulation of insulin- and gluconeogenesis-related responses

A deciduous tree belonging to the Combretaceae family, Terminalia chebula Retz. has a long history of traditional use in diabetes management. However, it is not fully understood how the extract of T. chebula exerts the antidiabetic effects. To identify the constituents responsibl...
