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
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 ...
Geologist says Curiosity's images show Earth-like soils on Mars
Soil deep in a crater dating to some 3.7 billion years ago contains evidence that Mars was once much warmer and wetter, says University of Oregon geologist Gregory Retallack, based on images and data captured ...
Innovative technique may transform the hunt for new antibiotics and cancer therapies
Antibiotic resistance is depleting our arsenal against deadly diseases and infections, such as tuberculosis and Staph infections, but recent research shows promise to speed up the drug discovery process.
Kudzu can release soil carbon, accelerate global warming
Clemson University scientists are shedding new light on how invasion by exotic plant species affects the ability of soil to store greenhouse gases. The research could have far-reaching implications for how ...
Straw albedo mitigates extreme heat
Wheat fields are often tilled immediately after the crop is harvested, removing the light-coloured stubble and crop residues from the soil surface and bringing dark bare earth to the top. Post-harvest tilling ...
Spicy plant cuts the mustard as nerve gas fighter
The white mustard plant, having added spice to our lives for centuries, may soon be put to a very different use—in the fight against chemical weapons, scientists said Wednesday.
Searching for drugs in dirt, researchers call on citizen scientists
(Phys.org) —Microbes are not only a rich source of disease, but also a rich source of medicines, and experts think many life-saving compounds produced by as-yet-unnamed bacteria are awaiting discovery. ...
