The Cold-Air Outbreaks in the Marine Boundary Layer Experiment model-observation intercomparison project (COMBLE-MIP) – Part 1: Model specification, observational constraints, and preliminary findings

Models struggle to represent the coupled microphysical, turbulent and radiative processes within widespread, long-lived marine cold-air outbreak (CAO) cloud fields, contributing to forecast and climate biases. Here we combine ground-based and satellite measurements to initialize...

Widespread endocrine-disrupting pollutant alters male courtship behavior in a livebearing fish

Abstract Sexual selection is a potent evolutionary force shaping both pre-copulatory courtship behavior and post-copulatory sperm traits, with male reproductive effort often adjusted to social and mating context. Endocrine-disrupting contaminants are predicted to alter how males...

Soil moisture and evapotranspiration in four temperate agricultural catchments of Southern Sweden under future climatic conditions

Study region We modelled four agriculturally dominated catchments that represent key agro-climatic production zones in southern Sweden: Tidan (58.37 N, 13.92E), Enköpingsån-Örsundaån (59.83 N, 17.0E), Saxån-Braån (55.96 N, 13.14E) and Gamlebyån-Loftaån (57.96 N, 16.30). These cat...

Accelerated lowland thermokarst development revealed by UAS photogrammetric surveys in the Stordalen mire, Abisko, Sweden

Organic matter decomposition in permafrost soils depends on factors such as soil pH, temperature, and redox conditions. Over lowland permafrost soils, these conditions are shaped by microtopography, which evolves with physical degradation, i.e., lowland thermokarst development. A...

Regularisation of regression trees by summation of p values

Abstract The standard procedure to decide on the complexity of a CART regression tree is to use cross-validation with the aim of obtaining a predictor that generalises well to unseen data. The randomness in the selection of folds implies that the selected CART regression tree is...

DARE to wear: digital health promotion and disease prevention using wearable devices

Global healthcare systems are under increasing strain to ensure long-term sustainability, necessitating a transition towards proactive, preventive healthcare strategies. Wearable sensor technologies are uniquely positioned to facilitate this paradigm shift by allowing continuous...

Formation of Refractory Monomethylmercury Pools by Particle Adsorption

Abstract Adsorption of mercury (Hg) onto particles is known to limit Hg availability for important biogeochemical processes, including the methylation of Hg and biological uptake of monomethylmercury (MMHg). However, the extent to which particle adsorption forms refractory Hg poo...

The Cloud Feedback Model Intercomparison Project (CFMIP) contribution to CMIP7

Cloud processes constitute one of the key uncertainties for climate change projections. The fourth iteration of the Cloud Feedback Model Intercomparison Project, CFMIP4, contributes to the Coupled Model Intercomparison Project phase 7 (CMIP7), by providing a set of global climate...

Beyond Blood and Urine: Decoding the Human Chemical Exposome across Matrices and Time

Abstract Environmental chemicals contribute substantially to the global burden of chronic disease, yet for most compounds now detectable in human biological samples, causal links to specific health outcomes remain poorly established. HRMS can profile thousands of chemical feature...

Several multiple sequence alignment-perturbing methods enhance AlphaFold3 sampling of alternative protein states

Abstract Protein function often involves multiple conformational states. Several multiple sequence alignment-perturbing strategies, including stochastic subsampling, clustering, and column masking, have been shown to enhance AlphaFold2 (AF2) sampling of alternative protein states...

Rewriting the Polesine Flood: Gender and Ecology in Sonia Aggio’s Magnificat

On 14 November 1951, the Polesine basin experienced one of the most severe floods recorded in modern Italian history. Despite its historical significance, the event remains marginal in environmental humanities scholarship. This article examines Magnificat (2022) by Sonia Aggio, a...

“Justifying Military Conscription”

ABSTRACT I argue that wartime military conscription can be justified only if potential conscripts have duties to enlist, or duties to participate in an enlistment lottery, that conscription forces them to discharge. I explore whether our interpersonal duties to rescue can ground...

Diamondiyne: A 3D Carbon Allotrope With Mixed sp–sp 3 Hybridization

ABSTRACT The creation of carbon allotropes is synthetically highly challenging, but their practical significance to science and technology cannot be underestimated. Here, we report the synthesis of a new carbon allotrope, diamondiyne, which is the second known one (after diamond)...

Expanding frameworks: Integrating vulnerability, exposure, and critical infrastructure to assess pluvial flood risks in New York City

Extreme precipitation events are increasing their frequency and intensity across the United States, posing growing risks to urban communities through pluvial flooding. Effective adaptation against pluvial flooding through structural and nonstructural measures requires understandi...

Gendered experiences of sublet housing platforms in Stockholm

Subletting, as an informal mode of arranging housing, has become an important segment of the housing market in Sweden and is often facilitated through online groups and platforms such as Facebook. However, little is known about how these digital platforms function as sites for th...

Deciduous forest, habitat diversity and distance to water - but not forest edges - drive bat activity in a managed forest-farmland mosaic in south-eastern Sweden

Understanding how landscape composition and configuration influence bats near their northern range limit is essential for their conservation in managed northern European forested environments. We investigated this in a forest–farmland mosaic of south-eastern Sweden. Using passive...

Problem-driven design methods for organizing collaborative learning: learning circles and change laboratories

Purpose This study aims to examine how two Nordic co-design methods, namely, learning circles (LC) and change laboratory (CL), support collaborative learning and system-level redesign in educational settings. The authors identify learning and facilitation principles that guide th...

36Cl concentrations from polar ice cores set new constraints on the Carrington event.

The Carrington event of 1859 CE is considered one of the largest geomagnetic storms of the observational era and often used as a benchmark for a worst-case scenario. Yet, there exists no robust evidence of an associated solar energetic particle (SEP) event of a significant magnit...

Invited perspectives: Towards usable compound event research

Abstract. Supporting stakeholders with science-based decision-making to mitigate and adapt to climate change impacts is a central mandate of the climate research community. In particular, mapping out scenario-dependent climate risk landscapes is one of the most pressing challenge...

Mechanistic insights into Nrf2- and PARP1-mediated radioresistance of glioblastoma stem cells under photon, proton, and carbon ion irradiation: An in vitro study

Glioblastoma multiforme (GBM) exhibits strong resistance to radiotherapy, partly driven by glioblastoma stem-like cells (GSCs) with enhanced redox homeostasis and DNA repair capacity. This study evaluated whether targeting Nrf2-mediated antioxidant signaling and PARP1-dependent D...
