DarkAgents: AI-Powered Multi-Agent System for Astroparticle Physics Research
Researchers have introduced DarkAgents, an open-source multi-agent AI framework that combines large language model reasoning with deterministic human-written code to automate complex theoretical astroparticle physics computations. The system was applied to the study of cosmological first-order phase transitions, fitting results to the NANOGrav nanohertz gravitational-wave spectrum. The framework also generates audit reports of assumptions and priors, and its test runs identified inconsistencies in some previously published fits in the literature.
DarkAgents is a newly proposed multi-agent system designed to orchestrate research pipelines in theoretical astroparticle physics by pairing the reasoning and code-generation capabilities of large language models (LLMs) with deterministic, human-verified code. The framework supports multiple LLM backends, including models from Mistral, Anthropic, OpenAI, and locally hosted models via Ollama. As a first demonstration, the system was applied to cosmological first-order phase transitions, beginning from a classically scale-invariant particle-physics model and culminating in a fit to the NANOGrav gravitational-wave spectrum. Outputs include best-fit model parameters, their experimental and observational constraints, and a structured audit report of the assumptions and priors involved — a feature the authors highlight as particularly important for astroparticle physics. Notably, the test runs uncovered inconsistencies in some fits reported in existing literature and produced new fits using a dissipative bulk-flow gravitational-wave template. The code is publicly available, and the paper spans 12 pages with 2 figures. While related AI-assisted approaches have been explored in collider physics and cosmology, DarkAgents specifically targets the model-building and multi-constraint challenges characteristic of astroparticle physics.

Gut Bacteria Enzyme Found to Break Down Heat-Processed Food Compounds, Producing Novel Biogenic Amines
Researchers have discovered that an enzyme in common gut bacteria can degrade N-epsilon-carboxymethyllysine (CML), a compound formed during thermal food processing, producing previously unknown biogenic amines. The enzyme, ornithine decarboxylase SpeC from enterobacteria, acts on CML and related modified lysine derivatives through a low-level 'underground' catalytic activity. This finding suggests a previously unrecognized communication axis between thermally processed dietary compounds and gut microbial physiology, with potential implications for host health.
Full-Length Gene Sequencing Reveals Two Distinct Bacterial Communities in Black-Legged Ticks Expanding Into Canada
Researchers used Oxford Nanopore full-length 16S rRNA gene sequencing to characterize the microbiome of Ixodes scapularis black-legged ticks collected in Nova Scotia, Canada, distinguishing between tick-adapted bacteria and environmentally acquired bacteria. The study comes as I. scapularis — the primary vector of Lyme disease — is rapidly expanding northward into Canada due to climate change. The findings suggest that environmentally derived bacteria in tick microbiomes are not mere contamination, which has implications for how tick microbiome data is collected and interpreted across surveillance studies.
Study Identifies Metabolic Link Between Cell Envelope Stress and Biofilm Formation in Bacteria
Researchers have discovered that the metabolite acetyl-CoA directly inhibits enzymes that degrade the bacterial signaling molecule c-di-GMP, connecting cell envelope biosynthesis stress to biofilm formation in Pseudomonas aeruginosa. The study found that sub-inhibitory concentrations of antibiotics targeting early peptidoglycan biosynthesis — but not other antibiotic classes — elevate c-di-GMP levels by reducing phosphodiesterase activity, with acetyl-CoA competing for the enzyme active site. Because the relevant enzyme domain is broadly conserved across bacterial species, this checkpoint mechanism may be widespread and could have implications for understanding antibiotic-induced biofilm responses.
