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.
New method of incorporating fluoride into drugs
Microbes in Central Park soil: If they can make it there, they can make it anywhere
Soil microbes that thrive in the deserts, rainforests, prairies and forests of the world can also be found living beneath New York City's Central Park, according to a surprising new study led by Colorado ...
Biochar alters water flow to improve sand and clay, study finds
(Phys.org) —As more gardeners and farmers add ground charcoal, or biochar, to soil to both boost crop yields and counter global climate change, a new study by researchers at Rice University and Colorado ...
Study helps assess impact of temperature on belowground soil decomposition
The Earth's soils store four times more carbon than the atmosphere and small changes in soil carbon storage can have a big effect on atmospheric greenhouse gas concentrations. A new paper in the journal Nature Cl ...
New method for observing chemical reactions in real and rapid time
(Phys.org) —A research team at the University of Delaware has developed a new method for observing chemical reactions in real and rapid time at the boundaries between soil mineral particles and water.
For legume plants, a new route from shoot to root
A new study shows that legume plants regulate their symbiotic relationship with soil bacteria by using cytokinins—signaling molecules— that are transmitted through the plant structure from leaves into ...
Carbon stored in the world's soils more vulnerable to climate change than expected
The response of soil microbial communities to changes in temperature increases the potential for more carbon dioxide to be released from the world's soils as global temperatures rise, scientists have revealed.
Home Microbiome Project announces results of study on household microbes
A person's home is their castle, and they populate it with their own subjects: millions and millions of bacteria.
Electric sparks may alter evolution of lunar soil
The moon appears to be a tranquil place, but modeling done by University of New Hampshire and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly ...
Climate change and the soil: Climate warming may not drive net losses of soil carbon from tropical forests
The planet's soil releases about 60 billion tons of carbon into the atmosphere each year, which is far more than that released by burning fossil fuels. This happens through a process called soil respiration. This enormous ...
