Where does charcoal, or black carbon, in soils go?
(Phys.org) —Scientists have uncovered one of nature's long-kept secrets—the true fate of charcoal in the world's soils. The ability to determine the fate of charcoal is critical to knowledge of the global ...
Sunlight stimulates release of climate-warming gas from melting Arctic permafrost, study says
Ancient carbon trapped in Arctic permafrost is extremely sensitive to sunlight and, if exposed to the surface when long-frozen soils melt and collapse, can release climate-warming carbon dioxide gas into ...
Unique microbes found in extreme environment
Researchers who were looking for organisms that eke out a living in some of the most inhospitable soils on Earth have found a hardy few. A new DNA analysis of rocky soils in the martian-like landscape on some ...
Carnivorous plant traps worms with sticky leaves
Plants eat the darndest things. Scientists have discovered a small flowering plant living in the sandy soils of Brazil that traps nematodes, or roundworms, with sticky underground leaves -- and gobbles them ...
Hong Kong researchers store data in bacteria
The US' national archives occupy more than 500 miles (800 kilometres) of shelving; France's archives stretch for more than 100 miles of shelves, as do Britain's.
Viking landers did detect organics on Mars
Missing piece inspires new look at Mars puzzle
(PhysOrg.com) -- Experiments prompted by a 2008 surprise from NASA's Phoenix Mars Lander suggest that soil examined by NASA's Viking Mars landers in 1976 may have contained carbon-based chemical building blocks ...
Mars explorer says we'll find life on other planets within 10 years
Within 10 years, we'll find life outside Earth -- that's the prediction of Peter Smith, the University of Arizona professor who led NASA's Phoenix Mars Mission.
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 ...
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 ...
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.
Soil biodiversity crucial to future land management and response to climate change
Research by scientists at The University of Manchester and Lancaster shows maintaining healthy soil biodiversity can play an important role in optimising land management programmes to reap benefits from the living soil.
The day before death: A new archaeological technique gives insight into the day before death
The day before the child's death was not a pleasant one, because it was not a sudden injury that killed the 10-13 year old child who was buried in the medieval town of Ribe in Denmark 800 years ago. The day ...
Greening of the Earth pushed way back in time
Conventional scientific wisdom has it that plants and other creatures have only lived on land for about 500 million years, and that landscapes of the early Earth were as barren as Mars.
