Modulation of the nociceptive withdrawal reflex in walking is not changed by the presence of tonic painNARA Subscribed
Tonic pain inhibits the nociceptive withdrawal reflex (NWR). NWR magnitude varies across the gait cycle, but it is unknown whether tonic pain affects this phase-dependent modulation of the NWR during walking. Sixteen healthy participants (mean ± SD age: 29 ± 9 years, 3 males) walked on a treadmill with and without tonic pain applied to the left arm. Lower-limb kinematics and electromyography (EMG) from bilateral biceps femoris...
Petrogenesis of isolated high-silica rhyolites in IcelandNARA Subscribed
High-silica rhyolites (HSRs) are rhyolites containing > 75 wt% SiO 2 on an anhydrous basis. In this contribution we have studied four Icelandic isolated occurrences away from central volcanoes (i.e., Icelandic volcanoes with a well-developed volcanic plumbing system): three in active rift zones (Mælifell, Ketilhyrnur and Prestahnúkur) and one in a flank/off-rift zone (Sultarfell). With no established central volcano, in which...
In response to increasing global interest in the utility of environmental DNA (eDNA) for non-invasively monitoring fish populations, the relationships between eDNA concentrations and electrofishing-derived relative biomasses and abundances were assessed for two ecologically distinct Australian native freshwater species: Murray cod ( Maccullochella peelii ) and bony herring ( Nematalosa erebi ). Species-specific eDNA assays tar...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...

Water pollution drives environmental degradation in a seasonally influenced Neotropical coastal riverNARA Subscribed
Aquatic and coastal ecosystems are increasingly altered by human activities, particularly through the removal of riparian vegetation, pollution, urbanization, and biological invasions. This study aimed to assess environmental conditions and identify a gradient of human disturbance in the Guaraguaçu River, located on the coastal plain of southern Brazil and subjected to multiple stressors. To achieve this, we evaluated land use...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
Effect of Stockholm Convention Listing on Temporal Trends of Halogenated Flame Retardants in Herring Gull Eggs in Canada (2008–2023)NARA Subscribed
Halogenated flame retardants (HFRs) are chemical additives used in many household and commercial products. Due to their persistence, long-range transport, bioaccumulative potential, and toxicity, several HFRs were listed for elimination or restrictions under the international Stockholm Convention on Persistent Organic Pollutants (SC-POPs). To understand how levels of HFRs in the environment have changed since being listed unde...
The 56th meeting of the Executive Committee (EC) of the International Committee on Taxonomy of Viruses (ICTV) was held in Bari, Italy, in July/August, 2024, and 115 submitted taxonomy proposals were reviewed. A total of 112 were subsequently ratified by the ICTV membership. An additional 9 error correction proposals were also approved in August 2025. This article lists the taxonomy proposals that have now been incorporated int...
