Warming pushes Western US toward driest period in 1,000 years
During the second half of the 21st century, the U.S. Southwest and Great Plains will face persistent drought worse than anything seen in times ancient or modern, with the drying conditions "driven primarily" ...
Buried fossil soils found to be awash in carbon
Soils that formed on the Earth's surface thousands of years ago and that are now deeply buried features of vanished landscapes have been found to be rich in carbon, adding a new dimension to our planet's ...
Study casts doubt on climate benefit of biofuels from corn residue
Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change.
30,000-year-old virus from permafrost is reborn
French scientists said Monday they had revived a giant but harmless virus that had been locked in the Siberian permafrost for more than 30,000 years.
Soil production breaks geologic speed record
Geologic time is shorthand for slow-paced. But new measurements from steep mountaintops in New Zealand show that rock can transform into soil more than twice as fast as previously believed possible.
Scientists identify mineral that destroys organic compounds, with implications for Mars Curiosity mission
Scientists have discovered that the mineral jarosite breaks down organic compounds when it is flash-heated, with implications for Mars research.
Capturing and storing carbon in soil: Is it real and can it scale?
Can beef production help restore ecosystems? A team of scientists, advisors and communications specialists are banding together to explore whether ranching management can create robust soils, watersheds and wildlife habitat ...
NASA launches groundbreaking soil moisture mapping satellite (Update)
NASA successfully launched its first Earth satellite designed to collect global observations of the vital soil moisture hidden just beneath our feet.
Soils could keep contaminants in wastewater from reaching groundwater, streams
With endocrine-disrupting compounds affecting fish populations in rivers as close as Pennsylvania's Susquehanna and as far away as Israel's Jordan, a new research study shows that soils can filter out and ...
High-speed imaging captures raindrops releasing clouds of aerosols on impact
Ever notice an earthy smell in the air after a light rain? Now scientists at MIT believe they may have identified the mechanism that releases this aroma, as well as other aerosols, into the environment.
Research finds salt tolerance gene in soybean
A collaborative research project between Australian and Chinese scientists has shown how soybean can be bred to better tolerate soil salinity.
Study casts doubt on mammoth-killing cosmic impact
Rock soil droplets formed by heating most likely came from Stone Age house fires and not from a disastrous cosmic impact 12,900 years ago, according to new research from the University of California, Davis. ...
Soil's large carbon stores could be freed by increased CO2, plant growth
An increase in human-made carbon dioxide in the atmosphere could initiate a chain reaction between plants and microorganisms that would unsettle one of the largest carbon reservoirs on the planet—soil.
New analyses of Martian chemical maps suggest water bound to sulfates in soil
A research team led by LSU Geology and Geophysics Assistant Professor Suniti Karunatillake reveals a spatial association between the presence of sulfur and hydrogen found in martian soil. The work by this ...
