Is DNA metabarcoding an option for formaldehyde‐preserved zooplankton time series?

Abstract The recovery of amplifiable DNA from formaldehyde‐fixed (FF) zooplankton samples has long been considered problematic, but advances in degraded‐DNA retrieval have renewed interest in FF samples. To access the information stored in long‐term zooplankton time series, we ev...

Outdoor Environmental Comfort, Public-Space Use and Perceived Sociability Among Ageing Populations: Integrating Field Surveys and Microclimatic Simulations

Outdoor environmental comfort is increasingly relevant amid climate change and population ageing because it affects well-being, behaviour and public-space use. However, the relationship between microclimatic conditions, environmental perception, and public-space use among older a...

Toward reliable solid-solid phase change materials for thermal energy storage: Polymer Fibrillar network-reinforced organic plastic crystals

Solid-solid phase change materials (PCMs) offer attractive advantages for thermal energy storage (TES), including leakage-free operation, reduced encapsulation requirements, and design flexibility. Among them, organic plastic crystals (OPCs) such as pentaglycerine (PG) and pentae...

A decagon wave around Saturn’s south pole

Saturn has a unique long-lived, nearly stationary hexagon wave close to its north pole that is coupled to an intense eastward jet. Despite decades of observation, no similar wave has been reported so far in the southern hemisphere or elsewhere on Saturn. Ground-based and Hubble S...

High‐Polarization‐Extinction Raman Conversion in Gas‐Filled Polarization‐Maintaining Hollow‐Core Fibers

ABSTRACT Gas‐filled hollow‐core fibers (HCFs) are versatile platforms for high‐power nonlinear optics, yet integrating robust polarization control remains crucial for advanced practical applications. Here, we demonstrate the generation of highly polarized Stokes light via stimula...

Moiré‐Induced Symmetry Breaking of Charge Order in van der Waals Heterostructures

ABSTRACT Layered materials that stack different lattice symmetries are rare in nature. Misfit layered chalcogenides, which combine square and hexagonal lattices of rocksalt monochalcogenides and transition‐metal dichalcogenides, provide a platform to explore how incommensurabilit...

New Approaches for Monitoring Edible Coating Quality Using Hyperspectral Imaging (HSI) and Chemometrics

Abstract Preserving fruit quality after harvest presents a major challenge for the food industry, and edible coatings are increasingly proposed as sustainable alternatives to synthetic packaging materials. This work offers a concise review of recent advances in edible coatings fo...

Biogeoclimatic Regions and Land-Use Structure Bacterial Biodiversity and Inferred Nitrogen-Cycling Potential in Headwater Stream Sediments

Abstract Microbial communities in freshwater ecosystems are structured by both natural environmental variation and anthropogenic pressures, yet how these drivers interact to shape biodiversity and ecosystem functioning remains poorly understood. Here, we assessed how biogeoclimat...

When Plain Language Deceives: Frequent but Generic Words and Misleading Sentence Simplicity in a Mobile Phone Advertisement—An Eye‐Tracking and Decision‐Task Study

ABSTRACT This study investigates how plain and apparently simple language can mislead readers in online advertising. Using eye‐tracking and a forced‐choice task, we compared an original smartphone advertisement with a revised version. The revision replaced frequent and generic wo...

Sensorimotor teleology and goal-directedness. An organismic framework for normative behaviour

Abstract Teleosemantics explains meaning by appealing to the biological norms that make error possible, but most work in the field still anchors those norms in evolutionary “selected-effect” functions. We develop an organismic alternative grounded in the self-maintenance of auton...

Academic mobility and identity in transition: comparative insights from multilingual scholars across higher educational systems

Purpose This paper aims to examine how bi- and multilingual academics reconstruct professional identities during international mobility and how they exercise agency in relation to language hierarchies, institutional expectations, and belonging across higher education systems. Des...

A compilation of global bio-optical in situ data for ocean-colour satellite applications – version four

Abstract. A global in situ dataset for validation of satellite products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version of the compilation, with data starting in 1996, extends to 2025, which is important for the validation of recent algorit...

Personalized Detection of Functional-State Changes Through Continuous Gait Monitoring: A Methodology for Assistive-Device Users

Lower limb mobility impairments resulting from neurological diseases, trauma injuries or aging significantly impact the quality of life of individuals by limiting their autonomy. Rehabilitation plays an important role in addressing the challenges of these impairments, with early...

Transcription-protein dissociation reveals disrupted cellular stress pathways in the prefrontal cortex of depression and schizophrenia subjects

Abstract Major depressive disorder (MDD) and schizophrenia (SCZ) are severe psychiatric disorders, the molecular mechanisms of which remain incompletely understood. Increasing evidence implicates neuroinflammatory signaling, autophagy dysregulation, and unfolded protein response...

Incidence, prevalence, and ketoacidosis at onset of type 1 diabetes in Spain: a systematic review and critical assessment of the available evidence

The incidence, prevalence and onset of type 1 diabetes (T1D) with diabetic ketoacidosis (DKA) in Spain remain insufficiently characterized, despite multiple regional analyses. This study aims to summarize and critically assess epidemiologic data in Spain, incorporating insights f...

Regression of Left Ventricular Hypertrophy in Primary Aldosteronism

BACKGROUND: Left ventricular hypertrophy (LVH) is frequently identified in patients with primary aldosteronism; determinants of LVH regression after targeted treatment are debated. We assessed LVH prevalence before and after adrenalectomy or mineralocorticoid receptor antagonist...

How Polymer ChainsRemember Their Crystalline Past:Simulations Uncover the Molecular Origin of Melt Memory

Abstract Melt memory in semicrystalline polymers is the remarkable ability of polymer chains to retain structural information from a prior crystalline state after being heated above the melting temperature. This phenomenon can induce extraordinary self-nucleation and strongly inf...

Availability and representativeness of freshwater macroinvertebrate data to enable Europe-wide assessment of biodiversity trends

Freshwater ecosystems, though covering less than 1% of Earth's surface, harbor around 10% of all species. Pressures like pollution, water extraction, and habitat loss can exhibit complex interactions in their effects on freshwater biodiversity. Understanding the effects of these...

Defect Topology Governs Lithiation Pathways in Graphite Anodes

ABSTRACT The electrochemical behavior of graphite anodes is strongly affected by structural disorder, yet graphite crystallinity is often described using averaged descriptors that do not resolve the underlying defect landscape. Here, we investigate a series of industrially releva...

Mechanochemically Prepared Supported Ionic Liquids for Efficient Glycerol Valorization to Glycerol Carbonate

Abstract The valorization of glycerol, a major byproduct of the biodiesel industry, into high value chemicals offers a sustainable pathway to support circular economy objectives within biorefineries. Among various transformation routes, the transesterification of glycerol with di...
