Hypobaric hypoxia exposure initiates splenic ferroptosis, reducing red pulp macrophages and exacerbating high-altitude polycythemia by impairing erythrophagocytosis and increasing red blood cell retention.

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

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.
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.
A survey of oxygen-dependent enzymes suggests new candidates for oxygen sensors, expanding potential mechanisms underlying hypoxia-related adaptations or diseases in humans.
