Genome-wide association study of idiopathic pulmonary fibrosis susceptibility using clinically curated European ancestry datasets

Daniel Chin, Tamara Hernández-Beeftink, Lauren J. Donoghue et al. · 2026 · European Respiratory Journal

ABSTRACT Background Idiopathic pulmonary fibrosis (IPF) is a rare, incurable lung disease with a median survival of 3-5 years after diagnosis. Treatment options are limited. Genetic association studies can identify new genes involved in disease that might represent potential new drug targets, and it has been shown that drug targets with support from genetic studies are more likely to be successful in clinical development. Previous genome-wide association studies (GWAS) of IPF susceptibility have identified more than 20 signals implicating genes involved in multiple mechanisms, including telome

Probiotics and Fermented Foods in Human Nutrition

Irene Dini · 2026 · Molecules

Fermented foods and probiotics represent complementary yet distinct components of human nutrition. Fermented foods are shaped by biochemical transformations driven by microbial metabolism, whereas probiotics are live microorganisms that may confer health benefits to the host. In both cases, bacteria, yeasts, and filamentous fungi mediate key metabolic activities that generate bioactive compounds and modulate host-microbiota interactions. During fermentation, microbial communities synthesize organic acids, peptides, exopolysaccharides, vitamins, and other metabolites that enhance food safety, s

Electric vehicle charging at the workplace: Experimental evidence on incentives and environmental nudges

Teevrat Garg, Ryan Hanna, Jeff Myers et al. · 2026 · Journal of Environmental Economics and Management

Aligning electric vehicle (EV) charging with periods of abundant clean energy is essential for decarbonizing transportation. In solar-dominated grids, this requires shifting charging to midday hours – when vehicles are typically parked at workplaces. Yet workplace charging networks operate under institutional constraints such as shared infrastructure, bundled parking and charging services, and limited willingness to require drivers to move vehicles, making time-of-day pricing and active management difficult to implement. In a natural field experiment (n = 629 drivers) across a large workplace

The extracellular matrix in inflammation and cancer

Wanting Zhang, Yuhang Xiang, Chen Lu et al. · 2026 · Molecular Biomedicine

The extracellular matrix (ECM) forms a dynamic structure around cells, providing environmental cues, mechanical support, and tissue protection. It is composed of fibrous proteins, glycosaminoglycans (GAGs), proteoglycans, and glycoproteins. The molecular, physical, and mechanical properties of the ECM regulate the motility, survival, and function of immune cells. In most cancers, inflammatory cytokines and proteases-particularly matrix metalloproteinases(MMPs)-released within the immune-infiltrated inflammatory microenvironment can remodel the ECM. Cytokines such as tumor necrosis factor-α (TN

GLP-1 and the cardiovascular system

Florian Kahles, Andreas L. Birkenfeld, Nikolaus Marx · 2026 · Journal of Clinical Investigation

The incretin hormone glucagon-like peptide-1 (GLP-1) exerts potent effects on glucose metabolism, prompting the development of therapeutic strategies that enhance activity of the GLP-1 receptor (GLP-1R) pathway. Inhibitors of dipeptidyl peptidase 4 (DPP-4) prolong the half-life of endogenous GLP-1 and typically achieve reductions in HbA1c of 0.5%-0.8%. However, large-scale cardiovascular (CV) outcomes trials (CVOTs) with DPP-4 inhibitors demonstrated CV safety but did not show a reduction in CV events. A second incretin-based therapeutic approach was the development of GLP-1R agonists (GLP-1RA

Abstract This article provides the first comprehensive global evidence on people’s fairness and efficiency preferences, beliefs about the sources of inequality and the efficiency cost of redistribution, and policy attitudes toward redistribution. Using a globally harmonized consequential experiment with more than 65,000 individuals across 60 countries, we show that the source of inequality plays a substantially larger role for inequality acceptance than the efficiency cost of redistribution. At the global level, implemented inequality increases by 85% when inequality is caused by merit rather
