Testing the strong equivalence principle with multimessenger binary neutron star mergers

Abstract The constancy of the gravitational constant G is a cornerstone of the strong equivalence principle and of general relativity, yet its possible temporal variation remains a key target in tests of fundamental physics. Gravitational-wave (GW) astronomy, especially when comb...

Higher inter-rater agreement but more low-risk judgments: the influence of rater experience on RoB 2 assessments

It remains unclear whether risk-of-bias judgments made using the revised Cochrane risk-of-bias tool for randomized trials (RoB 2) by less experienced raters, even after standard training, systematically differ from those made by experienced raters. Our study recruited 12 inexperi...

Synbiotic HQP08 Supplementation for Hair Loss and Depressive Symptoms: An Open-Label Pilot Study of Clinical Outcomes and Gut Microbiome Changes

Background: Gut microbiota dysregulation has been implicated in hair loss via the gut–skin axis, but human interventional data are limited. We previously showed that Bifidobacterium longum HK003 reverses alopecia-like phenotypes in mice. Methods: We conducted an open-label, singl...

Early transmission risks of Ebola disease outbreak caused by Bundibugyo virus in the Democratic Republic of the Congo

An outbreak of Ebola disease caused by Bundibugyo virus (BDBV) has been ongoing since April 2026, primarily in the Democratic Republic of the Congo. We estimated the initial reproduction number of BDBV at 1.85 (95% CrI: 1.09, 3.25), underscoring the urgent need for timely impleme...

Safety and satisfaction of voluntary medical male circumcision among men who have sex with men in China

PURPOSE: To investigate the safety and satisfaction of circumcision among men who have sex with men (MSM), as voluntary male medical circumcision (VMMC) may be an innovative and acceptable tool for HIV prevention among this population in the future. METHODS: Participants who volu...

Are individual differences in social behaviour a cause or a consequence of endoparasite infection in feral cattle?

Host–parasite interactions are often described as ‘vicious circles’, with infected hosts differing from their noninfected conspecifics in ways that can increase their parasitic load and risk of concurrent infections. However, the question of whether individual differences are a c...

Digest: Local adaptation of dormancy onset cues in a species expanding its range

Abstract In temperate climates, dormancy enables organisms to survive winter, with timing often tied to environmental cues, such as daylength, that differ along latitudinal gradients. Adaptation to these gradients is crucial during range expansion. Clark et al. (2026) found that...

Gender differences in prolonged grief: a network perspective on symptom interconnections and functional impairment

Background: While prior studies have reported gender differences in prolonged grief symptom severity, less is known about symptom interconnections and their associations with functional impairment. Clarifying these may inform more targeted bereavement care.Methods: A total of 1,0...

Deep learning to monitor the deep sea: a category‐oriented automated framework for quantifying animal behavior at hydrothermal vents

Abstract Increasing evidences show that fauna living in deep‐sea ecosystems exhibit various complex behaviors that remain understudied. Although several in situ observatories have been set up around the globe, the use of their imagery data to gain insights into animal behavior ac...

Distribution and viral load of canine respiratory coronavirus in naturally infected dogs: evidence from clinical sampling sites and tissue detection

Canine respiratory coronavirus (CRCoV) is a respiratory pathogen associated with the canine infectious respiratory disease complex (CIRDC). Although CRCoV is primarily considered a respiratory virus, its distribution beyond the respiratory tract remains poorly understood. This st...
