Understanding spatial and temporal evolution of progressive excavation damage zone in granitic rocks – development of a novel mine-by and laboratory experimental framework at the BedrettoLab

Abstract. The brittle damage around tunnels in the form of spalling is common in massive crystalline rocks subjected to high in-situ stresses. Understanding the short-term development and long-term evolution of the Excavation Damage Zone (EDZ) is particularly important for deep g...

A standardized permafrost ground temperature collection for Canada 2025

Abstract. Ground temperature is an essential variable for monitoring the thermal state of permafrost, developing models, and conducting fundamental research. However, the usability of GT data in Canada is often hampered by inconsistent file formats, a lack of metadata standardiza...

Descriptive analysis of dairy cow imports from the United States into Ontario, Canada between 2009 and 2019: implications for the risk of H5N1 introduction

Since first being identified in March 2024, infections of highly pathogenic avian influenza (H5N1) have been reported in over one thousand dairy herds in the United States. Canadian dairy cattle have remained free from H5N1 infection, due in part to the testing regulations for in...

Microplastics in stair-step moss and lake water on Baffin Island, Nunavut, reflect a local source component

Microplastics (MPs) are contaminants of emerging Arctic concern due to their adverse effects on ecosystems, yet lake water and shorelands on Baffin Island, Nunavut, remain understudied for contamination. To address this knowledge gap, we investigated microplastic pollution in mos...

Glucose amendments are associated with structural and hormonal shifts in a Fungal-Algal-Bacterial (FAB) consortium

Abstract The fungal-algal-bacterial (FAB) consortium composed of Euglena mutabilis, Talaromyces, and Acidiphilium acidophilum is a natural acid-tolerant assemblage whose heavy metal handling may depend on interspecies cooperation rather than a single-organism uptake alone. Here,...

Using Limestone to Assess the Impacts of Passivation and Ca-Silicate Formation on Lime Carbonation Efficiency for Looping Technology

Abstract Maximizing process efficiency in the lime looping process for direct air capture (DAC) is essential for reducing costs and energy demands to scale up this carbon dioxide (CO2) removal (CDR) technology. Here, we investigated two inefficiencies in the lime looping process:...

Acid Leaching for Carbon Sequestration with Prospects for Critical Metal Recovery

Abstract Reducing carbon emissions and supplying critical metals for the green energy transition are essential to limiting global warming to below 1.5 °C. Here, we propose heap leaching ultramafic material with sulfuric acid followed by sequential precipitation for nickel recover...

Performance of a 307 kHz acoustic telemetry system in a small freshwater lake

Abstract Background Acoustic telemetry is widely used to study the movements of aquatic animals, yet spatial and temporal variation in acoustic system performance can bias inferences if not properly accounted for. Here, we conducted the first field-based assessment of detection e...

The biogeography of giant viruses and interactions with Eukaryotes across European lakes

Abstract Advances in genomics have revealed a diversity of nucleocytoplasmic large DNA viruses (phylum Nucleocytoviricota) that infect eukaryotes, but their ecology beyond the oceans remains poorly understood. We recover 208 Nucleocytoviricota genomes, including 205 putative new...

Short-term exposure to artificial light at night has little effect on parental provisioning or nestling growth in a breeding aerial insectivore ( Tachycineta bicolor )

Abstract Increased urbanization has altered nightscapes on a global level, with artificial light at night (ALAN) often extending well beyond localized urban centers. In breeding birds, previous studies have shown that ALAN can disrupt circadian rhythms with subsequent impact on t...

On recent measurements of toponium threshold enhancement in entire-function-regulated nonlocal quantum field theory

Abstract The recent (not so recent now) data from the LHC has a reported threshold enhancement in top-antitop production, we want to present a reinterpretation of the the recently published data. We do this in nonlocal quantum field theory and we show that the observed threshold...

Little variation in field-based upper thermal tolerance among populations of a freshwater fish exhibiting strong life history differences

As aquatic ecosystems warm, intraspecific variation may contribute to population- and species-level resilience. Thermal tolerance is typically studied in the laboratory, which can control for acclimation but might mask population differences. We measured critical thermal maximum...

The Personal Is Professional: Judith Fetterley’s Amazing Grace

I have titled this brief commentary on celebrating Provisions and Judith Fetterley’s impact on literary studies “The Personal is Professional: Judith Fetterley’s Amazing Grace.” The first part of t...

Greenhouse gas emissions of subsea telecommunications cables: A comparative study of trans-Atlantic and trans-Pacific systems

Subsea cables are critical for international data exchange. Yet lifecycle assessments (LCA) remain scarce, leaving a critical gap in understanding both the climate impacts of these systems and wider global telecommunications networks. Drawing on a unique model of industry collabo...
