This study examines how bedrest affects gut and oral microbiomes in older adults, finding that inactivity reduces gut diversity and increases Bacteroides, while exercise mitigates these changes, and oral microbiome diversity is more strongly linked to frailty.

This study identifies 10 novel genomic loci associated with intrinsic capacity using GWAS on UK Biobank and CLSA data, revealing genetic correlations with cellular processes and traits related to healthy aging.

The paper models human aging as a stochastic network of health attributes and shows that network structure influences the recovery of observational health data.
