Evidence for cortisol production in a shark

Corticosteroids are essential regulators of numerous physiological functions in vertebrates, including energy balance, immune responses, osmotic balance and metabolism. The terminal corticosteroids are highly conserved across jawed vertebrates, where cortisol or corticosterone me...

Polyethylene biotransformation by an earthworm gut-derived Streptomyces sp.: insights into microenvironment-associated metabolism

Abstract Polyethylene (PE) is a highly recalcitrant polymer that resists microbial degradation owing to its hydrophobic and chemically inert structure. In this study, a Streptomyces sp. strain MH-1, isolated from the earthworm gut, was investigated for its interaction with PE und...

A new megaraptoran dinosaur from the Lower Cretaceous Wessex Formation, UK, and its implications for theropod evolution and biogeography

Abstract Theropod dinosaur remains from the Barremian (Lower Cretaceous) Wessex Formation of the Isle of Wight, UK, are rare and often fragmentary. Here, we present a previously undescribed braincase from this formation that represents a new coelurosaurian, Invictibellatrix amber...

Choline chloride-based deep eutectic solvents for efficient anthocyanin recovery from black rice: process, kinetics and nanoliposomal formulation

Abstract This study investigated the recovery and nanoliposomal formulation of anthocyanin-rich extracts from black rice using choline chloride-based deep eutectic solvents (DESs). Choline chloride/1,2-propanediol (DES2) produced the highest anthocyanin content, 85.5 ± 3.4 mg l−1...

Change in the demographic dynamics of a spatially structured population of a colonial waterbird after a perturbation affecting a large colony

Localized perturbations may affect spatially structured populations (SSPs) as a whole by altering dispersal between patches. Yet, such large-scale consequences remain poorly understood and may depend on the proportion of the SSP affected by the perturbation. Here, we used correla...

Hearing shapes: the Bouba–Kiki effect in adult domestic dogs

The 'Bouba-Kiki effect' is an example of spontaneous association between auditory and visual stimuli, described in humans as a case of sound symbolism, a predisposition linked to language. Recent evidence showed that 3-day-old chicks also exhibit a spontaneous association between...

Reshaping Insulin Fibrillation at the Nano-Bio Interface Using Carbon Quantum Dots: Implications for Amyloid Inhibition

Abstract Insulin (Ins), a 51-residue α-helical hormone, is prone to forming insoluble aggregates during administration, production, and storage, which poses significant challenges to its stability, effectiveness, and formulation. In this regard, nanoparticles have attracted treme...

Monograph 29 (Field-16): Global Jurisprudential Formalism—Live Mathematical Audit, Admissibility Filters, and the Absolute Demilitarization of Macro-State Conflicts

Monograph 29 (Field-16) formalizes Global Cybernetic Jurisprudence (A_jurisprudence), an architectural framework engineered to replace kinetic geopolitical warfare with live-streamed, mathematically rigorous proof audits. Operating under non-violence constraints (sigma_ahimsa), t...

Effectiveness of multi-component, dynamic begging displays as honest signals of nestling hunger

Abstract Parent–offspring communication depends on offspring signals that help parents assess need and allocate care. Nestling begging is often treated as a graded, information-rich and therefore honest signal of hunger, as predicted by costly signalling models. We quantified how...

The co-evolution of hominins and Stone Age culture

Human biological and cultural evolution are tightly intertwined; the two display dependent relationships and each influences the trajectory of the other. Archaeological evidence for hominin culture first emerges ca 3.3 million years ago, but increasing data attests to an earlier,...

Penelitian ini bertujuan membandingkan biaya relevan antara alternatif membuat sendiri dan membeli dari luar pada PT Indah Kiat Pulp & Paper Tbk. selama periode 2021-2025 dengan menggunakan analisis biaya diferensial. Data yang digunakan adalah data sekunder yang diolah dari lapo...

Surface-Engineered Polythiosemicarbazide Membranes via Chelation-Controlled Silver Nanoparticle Growth for Antibacterial and Underwater Oleophobic Performance

Abstract Biofouling continues to limit the performance of ultrafiltration membranes for oil–water separation, creating demand for materials that combine high flux, strong selectivity, and built-in antimicrobial activity. Here, we report a chelating polythiosemicarbazide (PTSC) ul...

Does pasture diversity enhance growth and nutritive characteristics of dairy pastures in south-eastern Australia?

Context Australia’s dairy production relies predominantly on grazed rainfed perennial ryegrass pastures. Multi-species pastures, including grasses, legumes, and herbs, have potential to improve pasture dry-matter (DM) production and nutritional value, relative to perennial ryegra...

An Open-Loop Endpoint Memory Model for Incompressible Vorticity with a Null-Distance Channel and a Two-Branch Time Plane: Endpoint Response, Non-identifiability, and Numerical Checks

We study a candidate passive extension of the local rotation of an incompressible viscous fluid. The vorticity \(\boldsymbol\omega=\nabla\times\boldsymbol v\) is passed, as a boundary value, to an auxiliary half-line ("null-distance channel") \(y\ge0\) on which a diffusion field...

A niche construction-based approach to evolution by natural selection without reproduction—proof of concept and implications

Abstract In past decades, conceptual analysis has established that evolution by natural selection (ENS) can occur without reproduction (Bouchard 2008 Philos. Sci. 75, 560–570 (doi:10.1086/594507); Papale, 2021 Synthese 198, 10 429–10 455 (doi:10.1007/s11229-020-02729-6)). The aim...

Gene-rich fungus gnat germline-restricted chromosomes are largely transcriptionally quiescent

Germline-restricted chromosomes (GRCs) constitute a unique class of chromosomes confined to germ cells. Arising in multiple evolutionarily distant lineages, GRCs have been identified in three insect families (non-biting midges, gall midges, and fungus gnats), each within the orde...

Painless Spontaneous Spinal Epidural Hematoma Mimicking Acute Ischemic Stroke: A Case Report

AIM: Spontaneous spinal epidural hematoma is a rare neurological emergency. Its painless variant is particularly uncommon and can easily be misdiagnosed as acute ischemic stroke, especially in patients receiving anticoagulant therapy. This study aims to enrich the clinical recogn...

Training the Next Generation of Future Surgical Residents: A Scoping Review and Proposal for an Undergraduate Curriculum From the Italian Polispecialistic Society of Young Surgeons

AIM: The transition from medical school to surgical residency is marked by a persistent gap between theoretical instruction and clinical readiness. In Italy, variability in training programs across centers creates persistent gaps in residents’ medical education. Scientific societ...

The Divergence of the Termini: On Charity, Constitution, and What Becomes of a Communion When Two Histories End Apart

This essay examines what becomes of a genuine interpersonal communion when two histories, once joined in love, terminate in radically different relations to God. Working within the Gaitan Topology and in dialogue with Catholic doctrine and Thomas Aquinas, it distinguishes charity...
