Downregulation of EPAS1 and EGLN1 mRNA Expression Associated With High‐Altitude Adaptive Genetic Variants in Sherpa Highlanders

open access: yesAnnals of Human Genetics, Volume 90, Issue 3, Page 202-214, May 2026.
ABSTRACT Background and Aims Sherpa highlanders exhibit remarkable tolerance to hypoxia, most likely due to genetic adaptations shaped by natural selection at high altitude. This study examined the roles of endothelial PAS domain protein 1 (EPAS1) and egl‐9 family hypoxia‐inducible factor 1 (EGLN1) in the genetic mechanisms underlying this adaptation ...

Cenozoic Time Constraints on the Evolution of a Gleysol‐Ferralsol‐Podzol Toposequence, Northwest Amazon Basin, Brazil

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
ABSTRACT Deciphering the time milestones of clay formation is crucial for modeling the evolution of major geological systems near the Earth's surface. In the present study, kaolinite samples collected along four vertical profiles within a Gleysol‐Ferralsol‐Podzol soil toposequence near São Gabriel da Cachoeira, NW Amazon Basin (Brazil) are dated using ...
