Postbiotic could reduce the risk of brain damage after a concussion

18/08/2026 - Giving mice a byproduct produced by gut bacteria reduced their risk of severe brain damage and cognitive difficulties after a traumatic brain injury

Global transmission architecture of VIM carbapenemases reveals host-specific dissemination strategies

17/08/2026 - Carbapenemase-producing Gram-negative bacteria carrying Verona integron-encoded metallo-β-lactamase (VIM) pose a persistent global threat, yet the mechanisms driving their worldwide dissemination...

Functional profiling of ESKAPE viromes uncovers resistance-limiting phage-host dynamics

17/08/2026 - ESKAPE pathogens drive clinical antibiotic resistance and intractable infections, severely compromising antimicrobial therapies. Bacteriophages are promising alternatives to antibiotics, yet their...

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...

Genetic diversity and population structure analysis of Ethiopian mustard (Brassica carinata A. Braun) accessions using simple sequence repeat markers

12/08/2026 - Brassica carinata A. Braun is an oilseed that originated in Ethiopia with a wide range of industrial and food applications. Exploring the genetic structure of the crop is crucial for breeding and...

Templated or fully Synthetic? Prompt construction as a confound in measuring LLM political stance beyond writing assistance

- Political stance detection in LLMs has long been dominated by closed-ended, multiple-choice political survey questions---originally designed for humans, and thus lacks the realism and nuance of...

Neuroevolution Arena: Nested Ecological Evaluation of Update-and-Inheritance Regimes across Neural Architectures

- Competitive artificial-life systems can rank trained controllers differently under training and ecological evaluation. We present Neuroevolution Arena, a GPU-accelerated spatial ecology of...

Bayesian inference on beta diversity via feature allocation models with imperfect detection

- Beta diversity quantifies variation in species composition across ecological communities and is fundamental for understanding biodiversity patterns across space and environmental gradients....

Response diversity can stabilize or destabilize community dynamics depending on the number of insensitive species

12/08/2026 - Investigating the factors that stabilize biological communities is a central topic in ecology. Response diversity, defined as variation in species responses to environmental change, has been proposed...

Physics-Informed Learning for Robust Acoustic Localization with Calibrated Uncertainty

- Recent advances in Passive Acoustic Monitoring (PAM) offer an opportunity to obtain ecological spatial point-process data at unprecedented scale. However, realizing this opportunity necessitates the...

Graphing the Everyday: A Neurosymbolic Approach to Eliciting Routines for Just-In-Time Adaptive Interventions

- Just-In-Time Adaptive Interventions (JITAIs) increasingly rely on conversational agents to elicit user routines, yet translating fluid human dialogue into rigid schedule data remains a significant...

Hardware is an AI Ethics Problem: Expert Visions for a Sustainable and Equitable Semiconductor Industry

- As the foundation of contemporary AI systems, the semiconductor industry is increasingly shaped by critical social, environmental, and geopolitical challenges. Nonetheless, prior research has often...

An IMU Dataset for Human Activity Recognition to Support Independent Living in Smart Homes (IMU-HAR-IL)

- This document introduces HAR-IMU-IL, a dataset developed for human activity recognition (HAR) using inertial measurement unit (IMU) sensors within a smart home environment with a focus to support...

Why Study Emergent Behavior When You Can Regulate It? Aligning Multi-Agent Systems with Reward Prediction

- Multi-agent simulations are widely used to study complex social and ecological systems, where rich and often unexpected emergent behaviors arise from local interactions. A large body of prior work...

Georeferencing Non-Gazetteered Place Names using Biological Specimen Records

- Biological specimen records collected by natural history institutions constitute a rich source of temporal geographic knowledge, capturing biodiversity information about regional landscapes as they...

Risk-Aware Decision Policies for Agents Under Noisy Perception

- Perception in biological systems is inherently noisy, requiring organisms to make decisions under uncertainty where misclassification can be costly or fatal. We present an Artificial Life...
