Evolutionary barriers to horizontal gene transfer in macrophage associated Salmonella.

This study measures the fitness effects of horizontally transferred genes from E. coli to Salmonella in infection environments, finding gene length and environmental factors significantly hinder HGT.

The Core Human Fecal Metabolome

This study characterizes the core human fecal metabolome through untargeted metabolomic analysis of populations along an industrialization gradient, revealing shared and industrialization-related metabolites.

Strategy guides feature recall of a single object in working memory task

This study investigates how repeating feature questions affects recall accuracy in a working memory task, finding that repeated probes degrade recall for both color and location.

Recalling a single object: going beyond the capacity debate

This study investigates recall accuracy for features of a single object across three experiments, finding that errors increase with the number of recall questions and question order, challenging slot and resource models of working memory.

CoproID predicts the source of coprolites and paleofeces using microbiome composition and host DNA content

The paper introduces a method to determine the source of coprolites and paleofeces using microbiome composition and host DNA content, distinguishing between human, canine, and non-fecal materials.

Biogeographic study of human gut-associated crAssphage suggests impacts from industrialization and recent expansion

This study examines crAssphage prevalence in human gut metagenomes, finding lower prevalence in hunter-gatherer populations and suggesting a recent expansion linked to industrialization.

The dental calculus metabolome in modern and historic samples

This study characterizes the metabolome of modern and historic dental calculus to identify patterns of metabolite persistence and loss over time.
