Music listening may decrease pain via psychobiological mechanisms. Music listening style (MLS) influences music processing: Music empathizers (ME) focus on emotional aspects of music, whereas music systemizers (MS) focus on structural aspects, potentially affecting processes of music-induced analgesia. The effects of the MLS on music-induced analgesia might depend on the source of music selection (i.

Heat Stress Drives Rapid Viral and Antiviral Innate Immunity Activation in Hexacorallia.

Mol Ecol

September 2025

Department of Ecology, Evolution and Behavior, Alexander Silberman Institute of Life Sciences, Faculty of Science, The Hebrew University of Jerusalem, Jerusalem, Israel.

The class Hexacorallia, encompassing stony corals and sea anemones, plays a critical role in marine ecosystems. Coral bleaching, the disruption of the symbiosis between stony corals and zooxanthellate algae, is driven by seawater warming and further exacerbated by pathogenic microbes. However, how pathogens, especially viruses, contribute to accelerated bleaching remains poorly understood.

State Key Laboratory of Herbage Improvement and Grassland Agro-Ecosystems, College of Ecology, Lanzhou University, Lanzhou, P. R. China.

Chromosomal fissions and fusions are common, yet the molecular mechanisms and implications in speciation remain poorly understood. Here, we confirm a fission event in one zokor species through multiple-omics and functional analyses. We traced this event to a mutation in a splicing enhancer of the DNA repair gene in the fission-bearing species, which caused exon skipping and produced a truncated protein that disrupted DNA repair.

Theory predicts that high population density leads to more strongly connected spatial and social networks, but how local density drives individuals' positions within their networks is unclear. This gap reduces our ability to understand and predict density-dependent processes. Here we show that density drives greater network connectedness at the scale of individuals within wild animal populations.

Coral reefs are threatened worldwide from unprecedented increases in ocean temperatures, resulting in corals gradually living closer to their maximum thermal threshold. With ocean temperatures expected to warm up to 3 °C by 2100, understanding the effects of chronic elevated baseline temperature is important in determining the thermal physiological limits of corals and developing realistic restoration strategies to ensure the future of coral reefs. Here, we tested the effects of 26 weeks (i.

In the last decade, the free energy principle (FEP) and active inference (AIF) have achieved many successes connecting conceptual models of learning and cognition to mathematical models of perception and action. This effort is driven by a multidisciplinary interest in understanding aspects of self-organizing complex adaptive systems, including elements of agency. Various reinforcement learning (RL) models performing active inference have been proposed and trained on standard RL tasks using deep neural networks.

Many insects rely on skylight polarization patterns to navigate their habitats. To perform this vital task, most insect species have evolved specialized ommatidia in the dorsal rim area (DRA) of their compound eyes, which are adapted to detect linearly polarized light in large patches of the sky. In this study, we conducted electrophysiological recordings of ultraviolet-sensitive photoreceptors in the DRA and other regions of the compound eyes in honeybees () and bumblebees () to map their receptive fields (RFs).

Background: The prevalence of mental health symptoms is substantially higher in incarcerated individuals than in the general public. However, little is known how different types of incarceration, including pre-trial and correctional detention as well as detention exclusively for deportation proceedings (administrative detention), are associated with mental health symptoms. We aimed to investigate the prevalence of mental health symptoms in this vulnerable population and examine the impact of different types of detention as well as risk factors on their mental health symptoms.

Brain plasticity, the brain's inherent ability to adapt its structure and function, is crucial for responding to environmental challenges but is usually not linked to a significant change in size. A striking exception to this is Dehnel's phenomenon, where seasonal reversible brain-size reduction occurs in some small mammals to decrease metabolic demands during resource-scarce winter months. Despite these volumetric changes being well documented, the specific microstructural alterations that facilitate this adaptation remain poorly understood.

Extensive research explores the relationship between deepening conflict over socio-cultural issues and stagnating social mobility, typically focusing on men. Upwardly mobile women are routinely mentioned as belonging to the progressive "winners" of the knowledge-based society, yet their experiences and politics have received far less attention. This paper theorizes and investigates how women view their individual and collective trajectories and how these views relate to perceptions of future opportunities and political attitudes.

Extant studies suggest that cognitive overload, as a nascent phenomenon, has become increasingly pervasive among university students, precipitating a multitude of detrimental consequences. Nevertheless, the adverse impacts of cognitive overload, particularly on Chinese higher education students, remain markedly underexplored in the extant literature. To improve academic understanding, this research combines quantitative data with the stimulus-organism-response (SOR) framework, constructing a robust theoretical model that elucidates the antecedents and sequelae of cognitive overload in relation to academic productivity in educational contexts.

The fundamental frequency (F0) is a key parameter for characterising structures in vertebrate vocalisations, for instance defining vocal repertoires and their variations at different biological scales ( population dialects, individual signatures). However, the task is too laborious to perform manually, and its automation is complex. Despite significant advancements in the fields of speech and music for automatic F0 estimation, similar progress in bioacoustics has been limited.

Thermal screening of coral source material is likely crucial to enhancing long-term restoration success under ocean warming. It is unclear, however, whether reef-based donor colonies retain their thermal tolerance in a nursery environment. Here, we used CBASS acute thermal assays to compare standardized thermal tolerance thresholds (ED50s) of donor colonies from Acropora cytherea and Acropora florida from two sites in Pulau Lang Tengah, Malaysia to their 'nursery propagules' reared in a common garden coral nursery over 365 days.

Meiotic maturation of vertebrate oocytes occurs in the near-absence of transcription. Thus, female fertility relies on timely translational activation of maternal transcripts stockpiled in full-grown prophase-I-arrested oocytes. However, how expression of these mRNAs is suppressed to maintain the long-lasting prophase-I arrest remains mysterious.

Genomic instability markers are important hallmarks of aging, as previously evidenced within the European study of biomarkers of human aging, MARK-AGE; however, establishing the specific metabolic determinants of vascular aging is challenging. The objective of the present study was to evaluate the impact of the susceptibility to oxidation of serum LDL particles (LDLox) and the plasma metabolization products of nitric oxide (NOx) on relevant genomic instability markers. The analysis was performed on a MARK-AGE cohort of 1326 subjects (635 men and 691 women, 35-75 years old) randomly recruited from the general population.

The covalent attachment of ubiquitin (Ub) to target proteins (ubiquitylation) represents one of the most versatile post-translational modifications (PTM) in eukaryotic cells. Substrate modifications range from a single Ub moiety being attached to a target protein to complex Ub chains that can also contain Ubls (Ub-like proteins) or chemical modifications like acetylation or phosphorylation. The entirety of this complex system is entitled as "the Ub code".

Background: Single base substitution (SBS) mutations, particularly C > T and T > C, are increased owing to unrepaired DNA replication errors in mismatch repair-deficient (MMRd) cancers. Excess CpG > TpG mutations have been reported in MMRd cancers defective in mismatch detection (dMutSα), but not in mismatch correction (dMutLα). Somatic CpG > TpG mutations conventionally result from unrepaired spontaneous deamination of 5'-methylcytosine throughout the cell cycle, causing T:G mismatches and signature SBS1.
