Enhancement of Endocannabinoid Signaling by Dual MAGL/ABHD6 Inhibition Reduces Neurodegeneration and Neuro-Inflammation Following AMPA-Mediated Excitotoxicity

Excitotoxicity mediated by the α-amino-3-hydroxy-5-methyl-4 isoxazolepropionic acid receptor (AMPAR) is a major contributor to neuronal degeneration and inflammation in various neurological disorders. The endocannabinoid system (ECS), specifically through the endocannabinoid 2-ar...

Stability of the expanding region of Kerr de Sitter spacetimes

We prove the nonlinear stability of the cosmological region of Kerr de Sitter spacetimes. More precisely, we show that solutions to the Einstein vacuum equations with positive cosmological constant arising from data on a cylinder that is uniformly close to the Kerr de Sitter geom...

Breaking the Blend: A multi-tracer kinematic decomposition method for IFS data applied to disentangling the AGN outflow and circumnuclear ring in NGC 5728 with JWST

Abstract Integral field spectroscopy (IFS) of the central kiloparsecs of active galactic nuclei (AGN) reveals a mixture of spatially coincident emission from star-formation and AGN feedback exciting the interstellar medium. Disentangling these components remains a challenge, as m...

Digital solutions for tackling mental health in cancer patients and their families: The ALTHEA project

Despite advances in cancer treatment, the growing global cancer burden underscores the need for comprehensive and supportive care to address the needs of patients and their families. However, access to psycho-oncological support remains often limited across healthcare systems. Th...

Dual Porphyrin Sensitized Photocatalytic System for Visible‐Light‐Driven CO 2 Reduction

Dye‐sensitized photocatalysis offers a powerful strategy for combining the molecular selectivity of transition‐metal catalysts with the robustness and charge‐separation capabilities of semiconductor materials. Herein, we report a dual porphyrin–sensitized TiO 2 platform for visib...

An Arctic climatology of particle number size distributions and cloud condensation nuclei during warm and moist intrusions

Abstract Recent studies indicate that warm and moist intrusions are significant sources of aerosols in the Arctic. Yet their contribution to different aerosol particle size modes, cloud condensation nuclei (CCN), and droplet number concentrations ( N d ) remains largely unconstra...

GRAPHERGIA Poster: Industrial-Scale Laser Modification of Graphene and Graphitic Anodes for High-Capacity and Fast-Charging in Lithium-Ion Battery Cells

The GRAPHEGIA project was present at Graphene Week 2026 (September 2026, in Porto, Portugal) sharing its research progress and results with the European graphene researchers’ and innovators’ community. Konstantinos Mylonas, Materials & Processes Engineer at PLEIONE Energy (Greece...

Estimation of Total VOC Emission and Ozone Removal Rates in a Primary School Classroom

Abstract Measurements of gaseous and particulate pollutants were conducted inside and outside a classroom in an urban area of Athens, Greece, using both reference instruments and low cost sensors. These data were used to evaluate indoor air quality and to estimate the emissions o...

Backbone Chemistry Determines Ion Dissociation and Nanostructure Morphology in Charged-Neutral Blends with Low-Molecular-Weight PEO

Abstract Charged-neutral polymer blends provide a versatile platform for controlling ion dissociation, nanoscale organization, and thermodynamic behavior through polymer chemistry, making them attractive materials for applications ranging from ion-containing soft matter to single...

Upcycling Agro-Food Industrial Biomass Waste into Functional Activated Carbon for Selective CO2 Capture and Supercapacitor Applications

Abstract Activated carbon (AC) materials were developed via a single-step method from three different biowaste sources and tailored for application in carbon dioxide (CO2) capture and electrochemical energy storage, combining the concept of biowaste valorisation with sustainable...

Highly Efficient Exciton Modulation in MoSe2/PdSe2 Heterostructures

Abstract We report a pronounced ∼6-fold enhancement of room-temperature A-exciton emission in a type-I MoSe2/PdSe2 van der Waals heterostructure, yielding a photoluminescence quantum yield of 6%, as compared to ∼1% for as-exfoliated monolayer MoSe2. This unusual enhancement is ac...

A new Earth Observation–based WRF configuration for urban regional climate simulations over Paris

In this study, Earth Observation (EO) data describing urban morphology and thermal properties are used to configure the urban representation of Paris in the Weather Research and Forecasting (WRF) model. Model performance is assessed in convective permitting simulations (3 km) in...

Gap-Entropy Testing (GET): A Framework for Structural and Distributional Differences

The classical two-sample problem is framed as the detection of differences in marginal distributions, in terms of location, scale, or overall shape. In this paper, Gap–Entropy Testing (GET) is proposed, a novel nonparametric framework that extends the two-sample paradigm by addin...

Immunomodulatory Amacstatins facilitate feeding and Rickettsia parkeri transmission by Amblyomma maculatum ticks

Ticks rely on salivary immunomodulators to sustain prolonged blood feeding and transmit pathogens, yet the protein effectors that mediate these processes remain incompletely defined. Here, we characterize three divergent cysteine protease inhibitors—Amacstatins—from the Gulf Coas...

The efficient star-forming regions of stripped-envelope supernovae

Abstract Massive stars ($\ge 8\, \rm {M}_{\odot }$) play a key role in shaping the interstellar medium of galaxies through stellar feedback. However, how these stars form and evolve before exploding as core-collapse supernovae (SNe) remains elusive. We compute for the first time...

Dicyandiamide-driven surface reconstruction of high-loading highly-dispersed Fe-N-C catalysts for enhanced acidic durability

The development of highly active and durable electrocatalysts with no platinum-group metals remains a critical challenge for the widespread commercialization of Proton-Exchange Membrane Fuel Cells. While Fe-N-C materials offer promising initial performance, their structural insta...

GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow

Abstract We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (z = 0.153), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt γ-ray emission and a Comptonized spectrum. The burst occurred at the edge of a blue host ga...

Future climate change favours the increase in abundance of smaller, shorter‐lived fish in the northeastern Mediterranean

Abstract As species distributions shift due to climate change, functional alterations may also occur within marine communities, potentially leading to ecosystem‐wide transformations. With Mediterranean marine ecosystems projected to undergo tropicalization, it is crucial to under...

Evolution of the Surface Composition of Graphene Oxide Films During Laser-Induced Reduction

Graphene oxide (GO) and reduced graphene oxide (rGO) are widely studied two-dimensional carbon nanomaterials for optoelectronic devices. Because the oxygen content and degree of reduction govern the electronic structure of GO-derived films, controlling the reduction process is es...
