The effect of ESG disclosure on firm value in the European context

Atif Mahmood, Asad Mehmood, Simone Terzani et al. · 2025 · Management Decision

Purpose The environmental, social and governance (ESG) topic has recently received increasing attention from scholars due to increasing regulations for firms’ non-financial disclosure with respect to environmental and social issues. For instance, the European Union (EU) recently issued the Corporate Sustainability Reporting Directive (CSRD) in December 2022 and implemented it starting in 2024 in member states. Non-financial disclosure is relevant for various stakeholders and could affect firm value. Therefore, this study aims to examine the effect of ESG disclosure on firm value in the EU cont

The Role of Ballasting, Seawater Viscosity and Oxygen‐Dependent Remineralization for Export and Transfer Efficiencies in the Global Ocean

Onur Karakuş, Cara Nissen, Christoph Voelker et al. · 2025 · Global Biogeochemical Cycles

Abstract The particulate organic carbon (POC) flux from the euphotic zone to the deep ocean is central to the biological carbon pump. It is typically evaluated using “export efficiency” and “transfer efficiency,” which reflect POC formation and sinking and carbon sequestration efficiency in the ocean's interior, respectively. Since observations of these metrics are limited, biogeochemical models can elucidate the controls of large‐scale patterns. This study uses the global ocean‐biogeochemical model FESOM‐REcoM, with a new sinking routine that accounts for ballast minerals, seawater viscosity,

Conceptual and methodological flaws undermine claims of a link between the gut microbiome and autism

Kevin J. Mitchell, Darren Dahly, Dorothy Bishop · 2025 · Neuron

The idea that the gut microbiome causally contributes to autism has gained currency in the scientific literature and popular press. Support for this hypothesis comes from three lines of evidence: human observational studies, preclinical experiments in mice, and human clinical trials. We critically assessed this literature and found that it is beset by conceptual and methodological flaws and limitations that undermine claims that the gut microbiome is causally involved in the etiology or pathophysiology of autism.

Limited overlap between genetic effects on disease susceptibility and disease survival

Zhiyu Yang, Fanny‐Dhelia Pajuste, Kristina Zguro et al. · 2025 · Nature Genetics

Abstract Understanding disease progression is of high biological and clinical interest. Unlike disease susceptibility, whose genetic basis has been abundantly studied, less is known about the genetics of disease progression and its overlap with disease susceptibility. Considering nine common diseases ( n cases ranging from 11,980 to 124,682) across seven biobanks, we systematically compared genetic architectures of susceptibility and progression, defined as disease-specific mortality. We identified only one locus substantially associated with disease-specific mortality and showed that, at a si

Abnormalities of lipid metabolism in the progression and treatment of depression

Xinchi Luan, Xuezhe Wang, Ying Shi et al. · 2025 · Frontiers in Psychiatry

Depression represents a global health challenge with complex etiology and significant societal impact. Recent advancements reveal a critical role of lipid metabolism dysregulation in the pathogenesis and severity of depressive disorders. This review elucidates the impact of lipid imbalance on depression highlighting how dyslipidemia not only makes individuals prone to depression but also exacerbates the progression of depression (including the occurrence of some comorbidities of depression). On this basis, we have summarized that abnormal lipid metabolism may serve as a diagnostic and therapeu

A defined community of core gut microbiota members promotes cognitive performance in honey bees

Amélie Cabirol, Andrew Quinn, Julie Schafer et al. · 2026 · Proceedings of the National Academy of Sciences

Abstract The composition of the gut microbiota has recently been identified as a cause of cognitive variability in humans and animals. Germ-free individuals and individuals exposed to an antibiotic treatment show severe alteration of their learning and memory performance measured in various cognitive tasks. While different species of bacteria are known to interact in the gut, their cumulative or synergistic effects on cognitive performance remain elusive. Here we established a defined bacterial community - composed of core members of the corbiculate bee microbiota - which enhances honey bees’

Habitat choice of the invasive Gammarus tigrinus and the native Gammarus salinus indicates weak interspecific competition

Jonne Kotta, Helen Orav‐Kotta, Kristjan Herkül et al. · 2024 · Työväentutkimus Vuosikirja

Following the establishment of the invasive gammarid amphipod Gammarus tigrinus the native gammarids almost disappeared from some habitats of the northeastern Baltic Sea.The aims of the current work were to experimentally study whether the habitat choice of G. tigrinus and G. salinus was similar and whether G. tigrinus modified the habitat selection of G. salinus, providing thus evidence that competition for space between the two species might explain the disappearance of the native gammarids from the study area.In general, the gammarid amphipods had a significant overlap in habitat selection.

Dual signaling pathways of TGF-β superfamily cytokines in hepatocytes: balancing liver homeostasis and disease progression

Roohi Chaudhary, Ralf Weiskirchen, Marcelo Ehrlich et al. · 2025 · Frontiers in Pharmacology

The transforming growth factor-β (TGF-β) superfamily (TGF-β-SF) comprises over 30 cytokines, including TGF-β, activins/inhibins, bone morphogenetic proteins (BMPs), and growth differentiation factors (GDFs). These cytokines play critical roles in liver function and disease progression. Here, we discuss Smad-dependent (canonical) and non-Smad pathways activated by these cytokines in a hepatocellular context. We highlight the connection between the deregulation of these pathways or the balance between them and key hepatocellular processes (e.g., proliferation, apoptosis, and epithelial-mesenchym

Pharmacoepigenetics of hypertension: genome-wide methylation analysis of responsiveness to four classes of antihypertensive drugs using a double-blind crossover study design

Marja-Liisa Nuotio, Heini Sánez Tähtisalo, Alexandra Lahtinen et al. · 2022 · Epigenetics

Essential hypertension remains the leading risk factor of global disease burden, but its treatment goals are often not met. We investigated whether DNA methylation is associated with antihypertensive responses to a diuretic, a beta-blocker, a calcium channel blocker or an angiotensin receptor antagonist. In addition, since we previously showed an SNP at the transcription start site (TSS) of the catecholamine biosynthesis-related ACY3 gene to associate with blood pressure (BP) response to beta-blockers, we specifically analysed the association of methylation sites close to the ACY3 TSS with BP
