The paper presents an ensemble model that improves predictions of perceptual similarity between odor mixtures using a curated dataset and collaborative challenge results.

The paper examines how social network cycles influence microbial strain-sharing in Honduran villages, finding that microbial transmission often occurs within clustered groups but not always aligned with social ties.

The paper develops PolyProf, a method to profile polymorphic toxin systems in metagenomes, showing it predicts microbiome development and disease-related dysbiosis.

The paper characterizes gut microbiomes in rural Honduras, identifying novel species and host-microbiome associations through metagenomic sequencing and genomic data integration.
