Bioenergy crops could store more carbon in soil

(Phys.org) —In addition to providing renewable energy, grass crops like switchgrass and miscanthus could store some of the carbon they pull from the atmosphere in the soil, according to a new study by University of Illinois ...

Bacteria get new badge as planet's detoxifier

A study published recently in PLOS ONE authored by Dr. Henry Sun and his postdoctoral student Dr. Gaosen Zhang of Nevada based research institute DRI provides new evidence that Earth bacteria can do something that is quite ...

Researchers use neutrons, simulations to examine soil carbon

(Phys.org) —Carbon dioxide in the atmosphere may get the lion's share of attention in climate change discussions, but the biggest repository of carbon is actually underfoot: soils store an estimated 2.5 trillion tons of ...

How does soil store CO2?

Global CO2 emissions continue to rise—in 2012 alone, 35.7 billion tons of this greenhouse gas entered the atmosphere. Some of it is absorbed by the oceans, plants and soil. They provide a significant reservoir of carbon. ...

Martian chemical complicates hunt for life's clues

The quest for evidence of life on Mars could be more difficult than scientists previously thought. A scientific paper published today details the investigation of a chemical in the Martian soil that interferes with the techniques ...

Old permafrost carbon released

Using indicator molecules, a team of researchers headed by ETH Zurich demonstrates that carbon stored in the Arctic permafrost is being mobilised in Eurasian river basins.
