A combination of composite-likelihood and gene network-based methods to investigate the impact of Denisovan introgression on the evolution of complex (i.e., polygenic) adaptive traits in high-altitude populations of Tibetan/Sherpa ancestry.
Comparative transcriptome analyses of human placenta reveal regulatory divergence between native highlanders and lowland immigrants living at high altitude, and a sex-biased pattern of genetic adaptation.
Hypobaric hypoxia exposure initiates splenic ferroptosis, reducing red pulp macrophages and exacerbating high-altitude polycythemia by impairing erythrophagocytosis and increasing red blood cell retention.
A survey of oxygen-dependent enzymes suggests new candidates for oxygen sensors, expanding potential mechanisms underlying hypoxia-related adaptations or diseases in humans.
Measurements of bar-headed geese flying in a wind tunnel in hypoxia reveal that these birds sustain aerobic flight at high altitude via a reduction in metabolism.

Radiotelemetric and genetic studies of peripheral tissue response show that a peripheral tissue can dynamically alter cardiovascular adaptation to changes in environmental oxygen.
