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.
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.
Niveles Altos de Contaminación en Chile se Relacionan Con Parrilladas de Hinchas del Fútbol
Misteriosos picos de contaminación—10 veces más altos que los niveles normales—ocurren en Santiago durante los partidos de fútbol televisados y son causados por decenas de miles de parrilladas, revelan nuevos resultados.

Scientists studying a cyanobacterium isolated from rock samples in the Atacama Desert found out how the bacteria extract water to live. Their results may help identify likely sites for life on Mars.
Pollution Spikes in Chile Tied to Soccer Fans’ Barbecuing
In Santiago, mysterious pollution spikes—tenfold above normal levels—occur during televised soccer matches and are caused by tens of thousands of barbecues, new results reveal.
Atacama’s Past Rainfall Followed Pacific Sea Temperature
