Nearby River is Pushing Up Peak of Mount Everest, Study Suggests

Han et al. found that erosion from a river network about 75 km from Mount Everest is carving away a substantial gorge; the loss of this landmass is causing the mountain to spring upwards by as much as 2 mm a year and has already increased its height by between 15 and 50 m over the past 89,000 years.

Mount Everest, also known as Chomolungma in Tibetan or Sagarmāthā in Nepali, is about 15 to 50 m taller than it would otherwise be because of uplift caused by a nearby eroding river gorge, and continues to grow because of it, according to new research. Han et al. found that erosion from a river network about 75 km from Mount Everest is carving away a substantial gorge; the loss of this landmass is causing the mountain to spring upwards by as much...

These 3,500-year-old kefir cheese samples are among the few dairy remains preserved more than 3,000 years and were produced by the Bronze Age Xiaohe population -- a population that possesses mixed lifestyles and techniques (e.g., farming, dairy production, hunting, etc.). Also, although early Xiaohe individuals show little genetic interaction with other populations, mitochondrial DNA data suggest maternal connections with East and West Eurasians. By recovering DNA information from ancient fermented dairy remains, Liu et al. investigated the lifestyle linked to the usage of fermented dairy by the Xiaohe population and explore the co-evolution between the fermented bacteria and their hosts.

Oceanic anoxic events are geologically abrupt phases of extreme oxygen depletion in the oceans that disrupted marine ecosystems and brought about evolutionary turnover. Typically lasting approximately 1.5 million years, these events occurred frequently during the Mesozoic era, from about 183 to 85 million years ago. One hypothesis suggests that anoxic events resulted from enhanced chemical weathering of Earth’s surface in a greenhouse world shaped by high volcanic carbon outgassing. Gernon et al. tested this hypothesis using a combination of plate reconstructions, tectonic-geochemical analysis and global biogeochemical modeling. Image credit: University of Southampton.
