This study identifies how maternal diet and genetics influence the human milk metabolome, showing diet explains the most variation and uncovering genetic associations with specific metabolites.

A pectin-based formulation preserves milk fat globule membranes in stored human milk, reducing lipase-driven degradation and maintaining sensory quality.

This study links the infant gut microbiome and resistome to bacterial strains in mother's milk using metagenomic samples from mother-infant pairs.

The paper identifies genetic loci influencing milk gene expression and links these to infant gut microbiome composition in breastfeeding mothers.

The paper investigates the association between human cytomegalovirus in breast milk and milk composition, infant gut microbiome, and infant growth.

This study uses Mendelian randomization to assess the causal relationship between plasma lipid levels and breast cancer risk, finding that higher HDL levels are associated with increased breast cancer risk.

The paper identifies non-identical-by-descent rare variants in population-scale whole genome sequencing data using a Bayesian hierarchical model and finds they correlate with higher mutation rates and genomic features.

The paper identifies mutation rate variation across populations and sequence contexts using the 1,000 Genomes Project data.

The paper identifies shared signatures of recent positive selection across 20 human populations and links them to potential biological mechanisms.
