Exploring the effects of ecological parameters on the spatial structure of genealogies

This study investigates how spatial ecological parameters affect genealogical structure through simulations and maximum likelihood estimation.

Emergence of Heartbeat Frailty in Advanced Age: Perspectives from Life-Long EKG Recordings in Mice

This study tracks EKG recordings in mice to identify age-related changes in heart rhythm variability, linking them to signs of cardiac and systemic frailty in advanced age.

Modelling the spatiotemporal spread of beneficial alleles using ancient genomes

This paper introduces a method to model the spatiotemporal spread of beneficial alleles using ancient genomes and applies it to West Eurasian data to estimate selection strength and diffusion rates.

The evolutionary history of Neandertal and Denisovan Y chromosomes

The paper analyzes ancient Y chromosomes from Denisovans and Neandertals, finding they split from a shared lineage around 700 kya, with Neandertal Y chromosomes diverging from modern humans around 370 kya.

The limits of long-term selection against Neandertal introgression

The paper shows that apparent declines in Neandertal ancestry in modern humans are artifacts, not evidence of negative selection, and finds no long-term decline in Neandertal ancestry over 45,000 years.
