Researchers Propose 'Conductome' Framework Using Bayesian Classifiers to Predict and Explain Human Behavior
Scientists have introduced the 'Conductome' — a theoretical and data-driven framework that defines behaviour as the complete set of factors predicting and explaining it, operationalised through Bayesian classification. The framework addresses the longstanding absence of a discipline-neutral definition of behaviour and a unified predictive model. It represents a potential methodological bridge across psychology, biology, and social sciences for understanding complex human actions.
Researchers have proposed the 'Conductome' as a new conceptual and computational framework for predicting and explaining behaviour, defining it as the complete ensemble of stimulus-response factors measurable for a given system. The approach is explicitly discipline-neutral, aiming to resolve the lack of consensus on what behaviour is and how it should be modelled across fields. By framing behaviour prediction as a classification problem, the authors argue that Bayesian classifiers are well-suited to building explainable, interpretable models that approximate the Conductome. The framework was validated on a dataset of 1,075 individuals with over 3,000 features, constructing a predictive model for sedentariness — a behaviour linked to obesity and metabolic disease. A subset of 396 features across 58 variables was analysed for effect size, coverage, statistical significance, and potential causal relationships. The study positions the Conductome as a scalable, data-driven tool applicable to a wide range of behavioural research questions.
What's missing
The study does not report external validation of the sedentariness model on an independent dataset, leaving generalisability uncertain. It is also unclear how the 1,075-person sample was recruited and whether it is representative of broader populations. The causal claims are described as 'potential' and the paper does not establish causal mechanisms, only statistical associations. As a preprint on bioRxiv, the work has not yet undergone peer review.

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.
