Casting light on the workings of illegal fishing markets

About 3.5 million fishing vessels ply the world’s oceans, providing livelihoods and food for millions of people. Sound management is key to fisheries’ sustainability, but illegal fishing, along with fishing overcapacity generally and environmental change, are putting many fisheri...

Salt‐Controlled Multistep Phase Separation in Hydroxypropyl Cellulose Colloids for Sustainable Adhesives

ABSTRACT Phase separation is an evergreen subject that shapes our understanding of how order and functionality emerge from disordered complex soft matter systems. Here, we report on the salt‐regulated transition from isotropic liquid‐liquid phase separation to anisotropic liquid‐...

Conformational Analysis and Ultraviolet Photodissociation of Valine in Solid Parahydrogen: Conformer-Specific Photolysis and Product Identification

The conformational composition and ultraviolet photochemistry of neutral valine isolated in solid parahydrogen were investigated using high-resolution infrared spectroscopy, ultraviolet photolysis, and density functional theory calculations. The observed infrared spectrum was ana...

Air Pollution Education: A Novel Curriculum for Pulmonary Fellows

Abstract Background Air pollution plays a significant role in human health, impacting respiratory outcomes. Despite decades of evidence detailing these health consequences as a result of both short and long-term air pollution exposure, the harms of air pollution exposure are infr...

Dental caries experience in first permanent molars and its associated factors among Iranian primary school-aged children: a cross-sectional study

Abstract Background Dental caries in first permanent molars is a highly prevalent condition in primary school-aged children and represents a substantial oral health burden in Iran. This study aimed to assess dental caries experience, based on the decayed, missing, and filled teet...

Spatial patterns and factors associated with vaccination uptake at follow-up among previously identified zero-dose children in Mchinji District, Malawi

Globally, more than 14 million infants remained zero-dose in 2024, having not received the first dose of diphtheria-tetanus-pertussis-containing vaccine (DTP1). In Malawi, national immunisation estimates may mask sub-district inequities, limiting the ability to identify and reach...

Bridging the social license gap: How community-directed communication shapes risk perception and acceptance of carbon capture and storage in the United States

Achieving global climate targets demands rapid deployment of new technologies, yet technological readiness risks outpacing the social license needed for deployment. Carbon capture and storage (CCS) exemplifies this challenge: deployment is expanding rapidly, but public awareness...

Using long-axial field-of-view dynamic PET/CT data to generate synthetic contrast enhanced CT images

ABSTRACT Purpose Dynamic whole-body [ 18 F]FDG PET/CT (DWB-PET/CT) imaging performed on long-axial field-of-view (LAFOV) systems enables the simultaneous assessment of tracer delivery and metabolism across extended anatomical regions. We investigated whether tracer delivery infor...

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food...

The symbolic power of decriminalization and recriminalization in shaping stigma toward people who use drugs in British Columbia

In January 2023, British Columbia (BC) implemented a three-year decriminalization pilot to reduce harms of drug criminalization and address stigma toward people who use drugs. In May 2024, the policy was amended to “recriminalize” drug possession, a reform that excluded most publ...

Ocean Governance and Marine Conservation: Institutional Work as a Lever for Ocean Sustainability

ABSTRACT Ocean governance presents one of the most complex environmental policy challenges of our time, requiring coordinated action across multiple scales, sectors and stakeholder groups. This paper applies institutional work theory to systematically examine how actors create, m...

Social connection and disconnection: Older adults’ life course perspectives on information and communication technologies

Abstract Background and Objectives Research has established that while most older adults use information and communication technologies (ICTs), loneliness and social isolation in later life is a pressing issue. Studies of older adults’ ICT use has largely been cross-sectional, fo...

Annotated genome assemblies of two temperate North American dung beetles, Canthon chalcites and Phanaeus vindex

Dung beetles serve as cultivators of their natural habitats, improving soil health and functions in both natural and anthropogenic environments. Despite their ecological importance, whole genome sequences for Scarabaeinae are limited. Here, we present the draft annotated genome a...

Terminology for describing the 24-h cycle of physical activity, sedentary behaviour, and sleep: a scoping review

Abstract Background Physical activity, sedentary behaviour, and sleep are three behaviours which occupy the 24-h cycle and interact to influence a multitude of health outcomes. Different terms are currently used to describe these behaviours collectively (e.g., movement behaviours...

Frailty and Surgical Invasiveness Are Independently Associated with Complications in Pediatric Spinal Deformity Surgery

Background: The purposes of this study were to determine whether frailty and surgical invasiveness are independently associated with perioperative outcomes and to describe the outcome rates when these 2 risk domains are considered together in pediatric patients undergoing spinal...

Morphology-based screening for sickle cell disease using low-cost automated microscopy and machine learning

Abstract Sickle cell disease (SCD) and β-thalassemia are the most common monogenic diseases, disproportionately affecting low- and middle-income countries, where low-cost and accurate diagnostic tools are needed to reduce the global disease burden. Although the sickling test is c...

Trans-affirming leaders’ professional capital: a critical mixed-methods study of educational policies, organizational practices and leadership on trans school workers' health

Purpose This study examines how policies, workplace climate and leadership contribute to trans PK-12 school workers' health and overall well-being. Design Using a critical mixed-methods design led by queer and trans scholars, we developed an online survey for trans school workers...

Application of a dynamic wound closure device in orthopaedic trauma patients following fasciotomy: A level-1 trauma center perspective and preliminary case series

Abstract The challenge of achieving delayed primary closure of fasciotomy wounds is well known, and multiple techniques of achieving either delayed primary closure or alternative forms of soft-tissue reconstruction have been described in the literature. However, a universally acc...

Endovascular Thrombectomy for Cerebral Venous Thrombosis: Current Status and Future Directions

Abstract Cerebral venous thrombosis (CVT) represents a relatively rare cause of stroke, yet it carries an overall rate of death or dependency of up to 15%. The mainstay of its management is therapeutic anticoagulation, either subcutaneously or intravenously in the acute phase, fo...

A Novel Approach to Characterizing Patterns of Real-World Upper-Extremity Use During Walking and Activities of Daily Living in People with Subacute Stroke

In accelerometer-based measurement, the inclusion of upper extremity (UE) activity during walking can overestimate real-world functional UE use in people post-stroke. This study introduces a comprehensive, accelerometer-based approach to examining real-world UE use, including the...
