Some southern beeches in the Andes have plumbed deeper for moisture as the surface has dried up. But doing so may deplete resources and undermine the trees’ future health.
Rain Makes Skulls Bigger—in Mice
New research shows how regional weather, shaped by towering mountain ranges, might influence the size and shape of local rodents.
Supervolcanoes Linger a While, Then Rush to Erupt
Geologists examined crystals in rock from four massive eruptions in the Chilean Andes.
Understanding Rare Rain Events in the Driest Desert on Earth
A new study reveals the atmospheric paths of storm events that can deliver a decade’s worth of rain in a few hours to the Atacama Desert.
Settlement of Rapa Nui May Have Been Doomed by a Dearth of Dust
Rapa Nui and Hawai‘i offer a tale of two island settlements: Hawai‘i was close enough to Asia for continental dust to help replenish soil nutrients depleted by agriculture. Rapa Nui wasn’t.
Understanding Tremors Through Tree Rings
Researchers look to carbon isotopes and cell-level wood anatomy to understand how seismic-induced changes in water availability affect tree growth.
Glassy Nodules Pinpoint a Meteorite Impact
Researchers working in Chile’s Atacama Desert have collected thousands of “atacamaites” that suggest a meteorite struck the region roughly 8 million years ago.
Chile’s Glacier Protection Law Needs Grounding in Sound Science
In the works for more than a decade, proposed legislation to protect glacial and permafrost environments in Chile suffers from uncertainties and omissions that could sow conflict instead of solutions.
Making the Universe Blurrier
Climate change appears to be directly and indirectly affecting the view from at least one observatory while threatening the existence of others.
Using Earthquake Forensics to Study Subduction from Space
Researchers combined satellite geodetic measurements of surface motion with a new geophysical data inversion method to probe the Chilean subduction zone in the wake of the 2010 Maule earthquake.
