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

Changes in pathways of lipid oxidation, glycolysis, and mitochondrial oxidative phosphorylation are common strategies to cope with high-altitude hypoxia, but some changes require longer evolutionary time to arise.

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.

Ostrich eggshell from the Liushu Formation in northwestern China push ancient protein preservation into the Miocene.

Prediction models for pulmonary hypertension based on a cohort inhabiting Tibet, China were established and validated.

Bar-headed geese lower their flight metabolic rates to fly in low-oxygen conditions.

Two therapsid clades, dicynodonts and cynodonts, independently acquired and developed an endotherm-like thermoregulation during the Late Permian period, that probably helped them to survive the major global climate and environmental fluctuations of the end-Permian.

Fine-grain mobility data empirically quantify the propensity for human mixing to be indoors across the US and improve understanding of the relationship between the physical environment and infection risk in light of global change.
