Fungal frontiers for sustainability: unlocking the hidden kingdom

Fungi have repeatedly delivered transformative advances across industries, from medicine to food to materials, yet these breakthroughs have emerged from a narrow base of organisms and well-studied systems. Although mycology has taken a big leap forward in the past decades because...

Deep phenotyping of white matter tissue composition in dementia with Lewy bodies

Abstract Background White matter signal abnormalities (WMSA) on MRI are common in dementia with Lewy bodies (DLB), and more severe WMSA have been associated with increased neurodegeneration in DLB. However, the underlying mechanisms of WMSA remain unclear. Single-Shell 3-Tissue C...

Acceptance of Organs From Deceased Donors: Results of a Global Survey.

Background: With <10% of transplantation needs being met, one contributing factor may be the potential subjectivity in transplant specialists' acceptance of organs. Such decisions, if influenced by knowledge and/or comfort gaps, warrant intervention. We assessed knowledge and com...

The first annotated checklist of the bees of Colombia reveals an overlooked diversity and areas with major data deficiencies

Background Most existing knowledge about bee biodiversity comes from temperate regions, where diversity is presumed highest—yet substantial data gaps across the tropics confound this pattern. Checklists are critical for documenting species presence, identifying knowledge gaps, an...

Mind the Gap: Disparities in Education on Organ Donation and Transplantation-Results of a Global Survey.

Background: Widely accessible education on organ donation and transplantation (ODT) is a tool to reduce waiting lists, as <10% of transplant needs are met (Global Observatory on Donation and Transplantation). We aimed to assess the current state of access to education on ODT worl...

Effect of dialkyl carbonates on soot precursor formation in ethylene laminar opposed-flow flames

Diethyl carbonate (DEC) and dimethyl carbonate (DMC) are environmentally friendly oxygenated fuel additives due to their low toxicity, engine compatibility, miscibility with conventional fuels, and sustainable synthesis from alcohols and CO₂. While DEC has demonstrated strong pot...

Scaling of an evidence-based intervention program in older people with diabetes and frailty in Latin America. Diabfrail-Latam clinical trial protocol

Objectives Diabfrail-Latam is a project funded by the Horizon 2020 program of the European Commission (EC) and the Global Alliance for Chronic Diseases (GACD). The main objective of this protocol is to describe the clinical validation of a multimodal intervention aimed at older p...

The impact of lying aversion and prosocial lies on cheating

Abstract This paper examines how prosocial motivations shape lying behavior in a strategic setting. Two players each privately choose a color in their mind, then draw a color at random, and report whether the two colors match. Both players receive a high payoff if at least one re...

Testing rational and behavioral predictions to long-term reversal: industry evidence from Latin America

The rational school predicts that return reversal may be significant in optimistic states but not in pessimistic ones. The behavioral school predicts that reversal may exist in industry segments with greater mispricing potential and more investor biases. We found little support f...

Traditional Ecological Knowledge of the Arhuaco People on Water Management in the Sierra Nevada de Santa Marta

Abstract This article analyzes the role of Traditional Ecological Knowledge (TEK) of the Arhuaco people in water management in the upper Ariguaní river basin, in the Sierra Nevada de Santa Marta (Colombia), in a context of accelerated socio-environmental transformation. From an e...

Do Bio-Inoculants Improve Composting Under Field Conditions? Comparative Study of Homemade, Commercial, and Laboratory-Developed Bio-Inoculants

Microbial bio-inoculants have been proposed to enhance composting efficiency; however, relatively few studies have evaluated their effectiveness under real operating conditions. This study evaluated three bio-inoculant application protocols, including an artisanal inoculant, a co...

Comparing Machine and Deep Learning for Electricity Theft Detection from Monthly Billing Data in an Emerging Energy Market

This study addresses a regime-conditioned question in electricity theft detection: when only monthly billing series and inspection-confirmed labels are available, which supervised model families recover irregular consumption without relying on the temporal resolution of advanced...

Professional identity formation and the limits of intelligibility in medical education: a queer reframing

Abstract Professional identity formation (PIF) has become a central tenet of medical education, yet its dominant assumptions leave a constitutive question underexamined: under what conditions can diverse configurations of knowledge, body, affect, and authority be recognized as le...

Anthropometric Characteristics, Neuromuscular Performance and Cardiorespiratory Fitness of Chilean Youth Soccer Players: A Cross-Sectional Study

Background and Objectives: Comprehensive physical profiling is important for monitoring athletic development in youth soccer players (YSP), yet integrated data from competitive South American players remain limited. This study aimed to characterize the anthropometric profile, neu...

Influence of Concrete Cover Thickness on Magnetic Field–Based Nondestructive Monitoring of Reinforced Concrete Structures

Abstract Structural health monitoring of reinforced concrete elements increasingly requires nondestructive techniques capable of assessing the internal condition of embedded reinforcement. This study investigates the feasibility of using the passive magnetic response of reinforci...

How Norms Depend on the Presence and Status of Observers: The Relational Contingency of Everyday Behaviors in 90 Societies

Norms are fundamental to social life, but basic questions about how they are affected by social context remain. Specifically, how do normative constraints depend on the presence and status of observers, and how do such relational contingencies vary across cultures? Using data fro...

Regional Hydroclimatic Sensitivity of Monthly Precipitation Anomalies to ENSO in the Colombian Andes and Orinoquia

El Niño–Southern Oscillation (ENSO) modulates tropical South American rainfall, but its Colombian expression is filtered by terrain, rainfall regime, moisture pathways, and atmospheric state. We quantify ENSO-related sensitivity of standardized precipitation anomalies in the Colo...

Presence of Microplastic-like Structures in a University Community and Its Companion Animals, from Bogotá-Colombia: An Exploratory Study

Microplastics (MPs) are widely distributed among humans and companion animals. Fecal samples from members of the university community at the Pontifical Javeriana University in Bogotá, Colombia, and their companion animals (pets) were analyzed to investigate a possible association...

Pituitary neuroendocrine tumors: imaging features, clinical relevance, and a proposal for standardized MRI reporting

Pituitary neuroendocrine tumors (PitNETs) are a heterogeneous group of lesions redefined in the 2022 WHO classification, emphasizing their neuroendocrine nature and biological variability. Despite advances in imaging, radiological reporting of PitNETs remains inconsistent and lac...
