Identification of a miRNA–mRNA Regulatory Networks in Placental Tissue Associated With Tibetan High Altitude Adaptation

Frontiers in Genetics, 2021
The Tibetan population has lived and successfully reproduced at high altitude for many generations. Studies have shown that Tibetans have various mechanisms for protection against high-altitude hypoxia, which are probably due, at least in part, to ...

High-altitude medicine

Indian Journal of Occupational and Environmental Medicine, 2010
Sojourns to high altitude have become common for recreation and adventure purposes. In most individuals, gradual ascent to a high altitude leads to a series of adaptive changes in the body, termed as acclimatization. These include changes in the respiratory, cardiovascular, hematologic systems and cellular adaptations that enhance oxygen delivery to ...

Convergent evolution in human and domesticate adaptation to high-altitude environments

Philosophical Transactions of the Royal Society of London. Biological Sciences, 2019
Humans and their domestic animals have lived and thrived in high-altitude environments worldwide for thousands of years. These populations have developed a number of adaptations to survive in a hypoxic environment, and several genomic studies have been ...

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

Advanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...
