Evidence of Earth’s Oldest Glaciers Found in South Africa
The ancient glaciers hint at an Archaean Earth that may have looked similar in some ways to our own time.
Frozen Riverbanks May Erode Faster in a Warming Arctic
Frozen flume experiments reveal the sensitivity of permafrost riverbank erosion to water temperature, bank roughness, and pore-ice content.
Biogeochemical Insights from a Major Amazonian River
Underrepresented in global carbon budgets, tropical rivers like Brazil’s Tocantins are in need of study to establish their baseline characteristics in the face of increasing global change.
Global Earthquake Analysis Seeks Elusive Foreshock Signal
Spotting foreshocks for what they are could help seismologists forecast large earthquakes.
Herbivore Diversity Helps Maintain Arctic Tundra Diversity
A long-term experiment in southwestern Greenland reveals that the presence of musk oxen and caribou helps stave off declines in Arctic tundra diversity brought on by climate change.
A Massive Landslide Beheaded One of the World’s Highest Peaks
Annapurna IV toppled in a Himalayan landslide, and scientists finally figured out when and how it happened.
Precisely Synced Clocks Pave the Way for New Science
Researchers working on Hawaiian mountain tops precisely synchronized two clocks with unprecedented efficiency, demonstrating the potential to create networks of such clocks for geodesy and more.
Mud Could Have Made Meandering Rivers Long Before Plants Arrived
New evidence from 1.2-billion-year-old rocks suggests that single, sinuous channels could have formed in muddy floodplain sediments without the stabilizing help of vegetation.
Education Lies Beneath the Clouds of Earth Observation
Cloud-based Earth Observation offers unique opportunities for education, but leveraging this requires new teaching methods that emphasize technical fundamentals, ethics, and stakeholder engagement.
