The paper compares gut microbiomes of Tsimane and Hadza populations to show that many microbes co-migrated with humans globally, but are now vanishing in industrialized populations.

This study compares lumbar paraspinal muscle size and density between the US Framingham Heart Study and Tsimane forager-horticulturalists, finding differences in muscle characteristics and age-related changes.

This study examines how APOE isoforms affect biological outcomes in industrialized and non-industrial environments, finding lifestyle-dependent effects and weak reproductive benefits for APOE ε4.

This study evaluates how face-to-BMI Vision Transformer models perform across diverse human populations, finding that training on population-specific data improves accuracy, while global training data enhances performance in underrepresented groups.

This study shows that inflammaging mediates age-related testosterone declines in men and that high testosterone with inflammation increases mortality risk.

This study examines how maternal glucocorticoids and behavior influence developmental trade-offs in wild baboon infants, finding that low maternal capital correlates with reduced play, independence, and growth.

The paper examines an energetic trade-off model linking inflammaging and immunosenescence using data from the US Health and Retirement Study and UK Biobank, finding evidence of TNFR1 and GDF15 mediating age-related immune declines and health risks.

The paper optimizes a reduced representation DNA methylation sequencing protocol for cost-effective, population-scale studies across species.
