Similarities and differences between dog–human and human–human relationships

Borbála Turcsán, Dorottya Júlia Ujfalussy, Andrea Kerepesi et al. · 2025 · Scientific Reports

Most dog owners in Western countries regard their dogs as companions or family members, prompting extensive research on the human-animal bond. However, many studies rely on broad categories or single dimensions, such as satisfaction or attachment, which can oversimplify the complexity of these relationships. In contrast, our study employed a multifaceted approach, examining the dog-owner bond across 13 relationship scales and comparing these scales to four different types of human relationships to reveal the human-like roles of dogs within a family. Participants (N = 717) characterized their r

Antibiotic use and gut microbiome composition links from individual-level prescription data of 14,979 individuals

Gabriel Baldanzi, Anna Larsson, Sergi Sayols-Baixeras et al. · 2026 · Nature Medicine

Disruptions in gut microbiome are implicated in cardiometabolic disorders and other health outcomes. Antibiotics are known gut microbiome disruptors, but their long-term consequences remain underexplored. Here we combined individual-level data from the Swedish Prescribed Drug Register with fecal metagenomes of 14,979 adults to examine the association between oral antibiotic use over 8 years and gut microbiome. In multivariable confounder-adjusted regression models, antibiotic use <1 year before fecal sampling was associated with the greatest reduction in species diversity, but significant asso

Population-scale sequencing resolves determinants of persistent EBV DNA

Sherry S. Y. Nyeo, Erin M. Cumming, Oliver S. Burren et al. · 2026 · Nature

Abstract Epstein–Barr virus (EBV) is an endemic herpesvirus implicated in autoimmunity, cancer and neurological disorders. Although primary infection is often subclinical, persistent EBV infection can drive immune dysregulation and long-term complications. Despite the ubiquity of infection, the determinants of EBV persistence following primary exposure remain poorly understood, although human genetic variation partially contributes to this phenotypic spectrum 1–3 . Here we demonstrate that existing whole genome sequencing (WGS) data of human populations can be used to quantify persistent EBV D

Unraveling the oral microbiome's role in Alzheimer's disease: From pathophysiology to therapeutic potential

Gilliana Rozenblum, Karima Ait‐Aissa, G. E. D. Zahran et al. · 2025 · Alzheimer s & Dementia

Oral dysbiosis contributes to Alzheimer's disease (AD) by promoting neuroinflammation. Pathobionts such as Porphyromonas gingivalis, Treponema denticola, and Fusobacterium nucleatum release virulence factors that induce amyloid beta aggregation and tau hyperphosphorylation, while the loss of commensals like Streptococcus salivarius and Neisseria spp. impairs anti-inflammatory protection, worsening neuronal damage. P. gingivalis is strongly linked to an increased risk of AD, especially in individuals with systemic conditions like diabetes, hypertension, and chronic kidney disease. Its presence

Ecology and spread of the North American H5N1 epizootic

Lambodhar Damodaran, Anna S. Jaeger, Louise H. Moncla · 2025 · Nature

Abstract Since late 2021, a panzootic of highly pathogenic H5N1 has devastated wild birds, agriculture and mammals. Here an analysis of 1,818 haemagglutinin sequences from wild birds, domestic birds and mammals reveals that the North American panzootic was driven by around nine introductions into the Atlantic and Pacific flyways, followed by rapid dissemination through wild, migratory birds. Transmission was primarily driven by Anseriformes, while non-canonical species acted as dead-end hosts. In contrast to the epizootic of 2015 (refs. 1,2 ), outbreaks in domestic birds were driven by around
