Supportive marriages may shape appetite control through oxytocin and the brain–gut axis
Vijay Kumar Malesu
News-Medical·2025
Supportive marital relationships are associated with lower BMI, fewer food addiction symptoms, higher oxytocin, stronger frontal brain responses to food cues, and favorable gut tryptophan metabolites.
These coordinated social, neural, hormonal, and gut pathways suggest a plausible biological link between emotional support and healthier eating regulation.

Ken Ishihara, Hideaki Shimazaki
Nature Communications·2025
<jats:title>Abstract</jats:title>
<jats:p>Neuronal ensemble activity, including coordinated and oscillatory patterns, exhibits hallmarks of nonequilibrium systems with time-asymmetric trajectories to maintain their organization. However, assessing time asymmetry from neuronal spiking activity remains challenging. The kinetic Ising model provides a framework for studying the causal, nonequilibrium dynamics in spiking recurrent neural networks. Recent theoretical advances in this model have enabled time-asymmetry estimation from large-scale steady-state data. Yet, neuronal activity often exhibits time-varying firing rates and coupling strengths, violating the steady-state assumption. To overcome this limitation, we developed a state-space kinetic Ising model that accounts for nonstationary and nonequilibrium properties of neural systems. This approach incorporates a mean-field method for estimating time-varying entropy flow, a key measure for maintaining the system’s organization through dissipation. Applying this method to mouse visual cortex data revealed greater variability in causal couplings during task engagement despite reduced neuronal activity with increased sparsity. Moreover, higher-performing mice exhibited increased coupling-related entropy flow per spike during task engagement, suggesting more efficient computation in the higher-performing mice. These findings underscore the model’s utility in uncovering intricate asymmetric causal dynamics in neuronal ensembles and linking them to behavior through the thermodynamic underpinnings of neural computation.</jats:p>

Eponine Moreau
Journal of Audiovisual Translation·2025
<jats:p>This paper examines Netflix’s most prominent transnational strategies and their impact on the AVT sector in general, and the work of subtitlers in particular. After a brief historical overview of the milestones that have led Netflix to become the most influential streaming platform, this paper explains how the company’s main strategies and practices, namely its release model and its self-produced originals, may impact the work of AV practitioners and the quality of the subtitles. It then explores the apparent paradox pertaining to Netflix’s localization practices, which seemingly serve its purpose of local integration – by allowing viewers to watch audiovisual content subtitled in their own language – while also conflicting with established national subtitling practices. More specifically, the discussion focuses on using the same template as a starting point to produce subtitles in multiple languages and Netflix Timed Text Style Guides.
Lay summary
This paper examines Netflix’s most prominent transnational strategies and their effects on the audiovisual translation sector in general, and the work of subtitlers in particular. After a brief historical overview of the milestones that have led Netflix to become the most influential streaming platform, the article explains how the company’s main strategies and practices, namely its release model, its self-produced originals and, more recently, its integration of AI and machine-translation tools, may impact the work of audiovisual practitioners and the quality of subtitles.
It then explores the apparent paradox pertaining to Netflix’s localization practices, which seemingly serve its purpose of local integration – by allowing viewers to watch audiovisual content subtitled in their own language – while also conflicting with established national subtitling practices. More specifically, the discussion focuses on using the same template as a starting point to produce subtitles in multiple languages and on Netflix Timed Text Style Guides. The paper concludes by considering the implications of Netflix’s transnational strategies for subtitling norms and by outlining avenues for future research.</jats:p>
