Understanding Cloud Droplets Could Improve Climate Modeling
The microphysical structure of cloud droplets affects behavior like precipitation. Current models may be underestimating how much these structures can vary within a single cloud.
In Arctic Soils, Methane-Eating Microbes Just Might Win Out over Methane Makers
Methanotrophs, including those that capture methane from the air, seem to outcompete methanogens in dry environments, a new study shows.
Global Climate Models Need the Nitrogen Cycle—All of It
Nitrogen plays important roles in areas including climate change, human health, and agriculture. A researcher argues that climate models would benefit from more fully incorporating its influence.
Tectonics and Climate Are Shaping an Alaskan Ecosystem
Biogeochemical research reveals the web of forces acting on a high-latitude microbe community in the Copper River Delta.
New 3D Model Reveals Geophysical Structures Beneath Britain
Using magnetotelluric data to identify subsurface electrically conductive and resistive areas, scientists can identify underground features and predict how space weather may affect infrastructure.
New USGS Map Offers an Interactive Look at the Rocks Beneath Our Feet
The Cooperative National Geologic Map is an interactive tool that builds on both cutting-edge technology and decades of mapping by geoscientists.
Compost and Biochar Could Boost Carbon Sequestration by Crushed Rock
Crushed rock additives may also help decrease soil emissions of other greenhouse gases, such as nitrous oxide and methane.
Isotopes Unearth History of Earthquakes in the Apennines
Dating of cosmogenic chlorine isotopes yields long-term estimates of fault activity in Italy, showing that periods of earthquakes and quiescence alternate over millennia.
Trust in Evanston Tap Water Depends on Gender, Race, and Past Experiences
Residents of the relatively high income Illinois city share why they trust the water in their taps—and others share why they stay away.
