Tumour acidosis remodels the glycocalyx to control lipid scavenging and ferroptosis

Aggressive tumours are defined by microenvironmental stress adaptation and metabolic reprogramming. Within this niche, lipid droplet accumulation has emerged as a key strategy to buffer toxic lipids and suppress ferroptosis. Lipid droplet formation can occur via de novo lipogenesis or extracellular lipid-scavenging. However, how tumour cells coordinate these processes remains poorly understood. He

Coping for climate resilience : climate emotions, empathy, and nature connectedness predict patterns of pro-environmental behavior and impairment in adolescents

In the face of climate change, today’s young people need to balance the challenges of being active and maintaining mental health. This study investigated climate resilience, meaning patterns of climate engagement and mental health among adolescents. Using latent profile analysis, we identified three profiles in a sample of N=603 Swedish adolescents: climate-resilient (17%, active and not impaired)

PON-Del predictor for sequence retaining protein deletions

Protein deletions are frequent among both disease-causing and tolerated variants. Several mechanisms at the DNA, RNA and protein levels can lead to deletions. Many deletions are misclassified in the literature and databases, especially when the mRNA is degraded by the cellular quality-control mechanism. We developed a novel predictor for sequence retaining protein deletions, i.e., variants that do

Interspecific variation in hatching success among three sea duck species at one breeding site in the Baltic Sea

Understanding variation in survival and reproduction is key for conservation and management of bird populations. By compiling and analysing data on hatching success (i.e. proportion of nests with at least one hatched egg) from Common Eider Somateria m. mollissima, Velvet Scoter Melanitta fusca and Red-breasted Merganser Mergus serrator, all breeding on a single island in the Baltic Sea, we demonst

Five-Year Experience of Nationwide Implementation of Colorectal Cancer Screening in Sweden

Background: Colorectal cancer (CRC) is a major health concern. In Sweden, a CRC screening program was implemented nationwide between 2019 and 2022. This study evaluated participation, colonoscopy adherence, and diagnostic outcomes for the program's first five years. Methods: The target group of screening was all residents 60–74 years old. Data were retrieved from SveReKKS, the Swedish national qua

Traceability in the Indian dairy industry : concept and practice

The rise in milk adulteration and contamination, fraud incidents and improper handling necessitates effective traceability systems in the Indian dairy industry. Thus, this review investigates current trends, associated challenges, traceability and its fundamental applications to address food safety and quality issues. The paper covers the evolution of milk adulteration and contamination detection

Navigating hybrid governance : a longitudinal comparison of university reforms in Denmark and Sweden

Purpose – This article’s purpose is to examine how the balance between autonomy (stewardship) and control (principal-agent) has evolved over 2 decades through a comparative longitudinal study of university governance reforms in Denmark and Sweden. Design/methodology/approach – Employing a longitudinal comparative case study design, the study draws on extensive document analysis and applies a theor

What if eye…? Computationally recreating vision evolution

Natural selection has produced diverse vision systems, from simple patches of photoreceptors to complex camera eyes, representing just one set of evolutionary outcomes. Computational evolution offers a way to systematically test hypotheses, isolate individual factors, and ask the “why” questions behind vision. We recreate vision evolution by coevolving eyes and behaviors in embodied agents and use

Wall-to-Wall Mapping of Forest Canopy Height using ICESat-2 Data and Multi-source Remote Sensing Images in a Machine Learning Framework

Forest Canopy Height (FCH) is one of the key variables for understanding forest structure distribution and growth. Remotely sensed data such as the NASA Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) ATL08 provides accurate FCH measurements; however, its point-based nature limits spatial continuity. This study addresses the challenge by generating a continuous FCH map over the West Usambara

Nutritional adequacy of the EAT-Lancet diet : a Swedish population-based cohort study

BACKGROUND: The EAT-Lancet planetary health diet emphasises plant-based foods while including moderate amounts of animal-sourced foods. Simulation-based modelling studies suggest that the diet can provide adequate micronutrients, but concerns remain about potential deficiencies as studies have used different methodologies and few have assessed nutrient intakes using both dietary and biomarker data

Neuronal networks quantified as vector fields

The function of the brain is defined by the interactions between its neurons. But these neurons exist in tremendous numbers, are continuously active, and densely interconnected. Thereby, they form one of the most complex dynamical systems known and there is a lack of approaches to characterize the functional properties of such biological neuronal networks without resorting to dimensionality reduct

Takotsubo Cardiomyopathy : An Exploration of the Intersection Between Stress, Coronary Dysfunction, and Cardiac Outcomes

Takotsubo syndrome (TTS) is an acute, reversible form of left ventricular dysfunction, typically triggered by emotional or physical stress. The hallmark feature is reversible regional wall motion abnormality extending beyond a single coronary distribution, most commonly presenting with an apical ballooning pattern. The pathophysiology is multifactorial, encompassing neurohormonal dysregulation, ca

Mitigation of groundwater salinity vulnerability through land cultivation scenarios

Groundwater in most parts of the world is an important source of agricultural water supply for food production. Soil salinization, however, threatens groundwater quality and may cause irreparable damage to agricultural land. A key to tackling this threat is to analyze the link between agricultural crop water requirements and groundwater quality. This study aimed to investigate salinity effects on

Global molecular landscape of early MASLD progression in human obesity

Metabolic dysfunction-associated steatotic liver disease (MASLD) is often asymptomatic early on but can progress to irreversible conditions like cirrhosis. Due to limited access to human liver biopsies, systematic and integrative molecular resources remain scarce. In this study, we performed transcriptomic analyses on liver and metabolomic analyses on liver and plasma samples from morbidly obese i

Background Assessment of myocardial sympathetic innervation with iodine-123-metaiodobenzylguanidine ([123I]mIBG) scintigraphy is conventionally performed by determining the heart-to-mediastinum ratio (HMR) on planar images. This study aimed to investigate the feasibility of determining HMR from reprojected [123I]mIBG planar images derived from tomographic data by a ring-configured cadmium-zinc-tel

Fullerene derivative integration controls morphological behaviour and recombination losses in non-fullerene acceptor-based organic solar cells

The complex and varied relationship found in intermolecular interactions within the photo-active layers plays a decisive role in determining the photovoltaic energy conversion and overall device performance of organic solar cells (OSCs). Among different approaches, the ternary blend strategy serves as an effective technique to control the morphology within the active layer in OSCs. In this work, P

Achieving global immunity against hepatitis A through universal vaccination : a position paper from the European Society of Clinical Microbiology and Infectious Diseases Study Group for Viral Hepatitis

Hepatitis A virus (HAV) remains a preventable cause of acute viral hepatitis, with an estimated 159 million new infections and 39 000 deaths in 2019. Although improved care and hygiene reduced deaths, global incidence rose by approximately 4%, driven by increased symptomatic cases and population growth. The availability of safe and highly immunogenic vaccines and the absence of chronic carriage ma
