Increments of melt trapped in crystals reveal upper crustal magmas in the Main Ethiopian Rift are rich in water and other volatiles, leading to extensive diffuse degassing and hydrothermal systems.Read More »Biogeosciences
Research at an experimental lake suggests that phosphorus inputs from runoff may affect the health of aquatic ecosystems long after external additions of the nutrient are reduced.Read More »Geohealth
Fine particulate matter from dust storms can exacerbate respiratory diseases, and now scientists have shown that critical care hospital visits spike during and after such events.Read More »Geochemistry, Mineralogy, Volcanology
Ocean alkalinity plays a major role in ocean’s carbon uptake, in buffering, and in calcium carbonate production and dissolution, and it impacts and is affected by various biogeochemical processes.Read More »Atmospheric Sciences
Fieldwork is revealing a history of landscape evolution over the past 5 million years that links climate change and river capture to critical mineral resources across the Alaska-Yukon border.Read More »Geochemistry, Mineralogy, Volcanology

A colossal volcanic eruption at Santorini, Greece, 3,600 years ago sent the island’s Bronze Age population fleeing for their lives. Where did the people go?Read More »Atmospheric Sciences
Using climate and habitat modeling, researchers show that solar dimming caused by an asteroid impact would have plunged the world into an “impact winter” and decimated dinosaur habitats.Read More »Planetary Sciences
Humans found hundreds of thousands of craters on Mars greater than 1 kilometer in diameter, but now computers automate the process delivering crater counts as well as geologically meaningful ages.Read More »Geochemistry, Mineralogy, Volcanology
Flat-slab subduction appears to have played a minor role in the growth of the Southern Central Andes, with evidence for eastward migrating deformation.Read More »
