The bacteria that make cheese taste so good may also benefit your gut

17/08/2026 - Scientists studying three artisan British cheeses found that the microbes responsible for their distinctive flavors may also offer surprising benefits for gut health. As the cheeses matured, helpful...

Altered Dorsolateral Prefrontal Glutamate Dynamics During Working Memory in Trauma-Exposed Individuals With and Without PTSD: A 7T Functional Magnetic Resonance Spectroscopy Study

16/08/2026 - Post-traumatic stress disorder (PTSD) has been associated with impairments in cognitive function, including working memory, and may involve altered glutamatergic regulation in the prefrontal cortex....

Drinking orange juice every day may change thousands of genes

13/08/2026 - Orange juice may have a much bigger effect on the body than scientists once realized. Drinking it regularly appears to influence genes tied to inflammation, blood pressure, metabolism, and blood...

SCOUT: Symmetric Consensus Outlier Detection for Failure Localization in LLM Pre-Training

- In LLM pre-training, synchronization propagates rank-local stalls, slowdowns, and numerical errors into job-wide symptoms, obscuring their origin. Existing diagnosis often relies on in-process...

Physics-informed Diffusion Generative Model for Time-Series Data Synthesis in Dynamic Systems

- Industrial time-series signals, such as turbine temperature and rotational speed in aero-engines, are essential for monitoring the health and operational status of complex dynamical systems. However,...

ComBodied Agents: a New Paradigm of Human-Centric Agentic AI

- After an older adult misses a medication dose, a software agent can send another reminder and an embodied agent can bring the medication. Yet neither explains whether the person forgot, is confused,...

Shaping the notion of #wellbeing in the therapy culture context: an analysis through Instagram narratives

- The aim of this paper is to (1) identify textual and visual themes and sub-themes associated with the #wellbeing hashtag on Instagram, (2) assess their varying levels of engagement and (3)...

When Your State Estimator Has Lost The Plot: Detecting Estimator Failures Via Spectral Analysis

- Reliable onboard state estimation is essential for safe robotic operation, yet unmodeled disturbances, such as sensor aliasing or out-of-distribution noise, still cause estimators to degrade or fail...

Mapping the Climate-Health Evidence Base (2007-2023): A Bibliometric, Statistical, and NLP Multi-Label Text Analysis of 22,695 Records

- We analyzed a curated climate--health bibliographic corpus of 22,695 multi-labeled records from 2007--2023 to characterize growth, thematic concentration, and evolving methods. Annual publication...

A full software stack for epidemic disease management: Unlocking the joint potential of software technology and supercomputing

- Infectious diseases remain a major threat to human societies. During the recent COVID-19 pandemic, mathematical modeling and extensive computer simulations proved highly effective in supporting...

Bayesian measurement error modeling of latent time series structure to assess the impact of pollutants on health

- The association between levels of air pollution and mortality rate is well-established, but quantifying the magnitude of the effect is sometimes complicated by limitations in the data. In this paper,...

Generalized Linear Markov Decision Process

- Offline reinforcement learning for longitudinal studies often faces two linked challenges: rewards may be binary or bounded, and reward observations may be available only for a subset of trajectories...

Survey-robust uncertainty quantification in generalised additive models for location, scale, and shape

- Conventional mean-only regression models are often too restrictive for the analysis of complex survey data, where interest frequently extends beyond the conditional mean to other aspects of the...

Ephrin Signaling Patterns Sensory Neurons During Tissue Homeostasis in Planarians

12/08/2026 - Eph and ephrin genes encode receptor-ligand pairs that mediate contact-dependent cell signaling and are essential for nervous system development. However, less is known about the role of Ephrin...

Explainable Machine Learning-Based Security and Privacy Protection Framework for Internet of Medical Things Systems

- The Internet of Medical Things transcends traditional medical boundaries, enabling a transition from reactive treatment to proactive prevention. This innovative method revolutionizes healthcare by...

Deep Multimodal Wearable Sensor Fusion for Detection of Body-Focused Repetitive Behaviors

- Body-focused repetitive behaviors, such as hair pulling and skin picking, are compulsive motor actions commonly associated with obsessive-compulsive and anxiety disorders. Their early, objective...

Does ChatGPT score research quality differently by gender?

- Large Language Models (LLMs) are being considered for research evaluation, raising concerns about the introduction of AI bias. This study investigates whether ChatGPT research quality scores differ...

ELICITED: EHR-grounded Longitudinal Interactive Conversations for Information-seeking Triage Evaluation and Decision-making
