Sex differences in immune function and disease risk are not easily explained by an evolutionary mismatch

This study examines sex differences in immune function and disease risk across populations, finding no consistent support for the evolutionary mismatch hypothesis.

Early life adversity has sex-dependent effects on survival across the lifespan in rhesus macaques

This study examines how early life adversity affects survival in male and female rhesus macaques, finding sex-dependent differences in mortality risk across the lifespan.

Adaptations to water stress and pastoralism in the Turkana of northwest Kenya

The paper identifies genetic regions associated with adaptation to water stress and pastoralism in the Turkana people using genome sequencing.

Diet unmasks genetic variants that regulate lifespan in outbred Drosophila

This study identifies lifespan-altering genetic variants in Drosophila under different diets, showing context-dependent effects and genotype-by-environment interactions.

Urbanization and market-integration have strong, non-linear effects on metabolic health in the Turkana

The paper examines how urbanization and market integration affect metabolic health in the Turkana, finding non-linear health declines with increasing urbanicity and early life exposure to urban environments.

Dominance rank-associated immune gene expression is widespread, sex-specific, and a precursor to high social status in wild male baboons

The paper examines how social status affects immune gene expression in wild baboons, finding sex-specific patterns where high-status males show increased pro-inflammatory gene expression, which precedes rank attainment.
