Dirty pool: 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.
Recycling water in space
During the last space shuttle flight, astronauts will test a new method for recycling 'used' water. Water is essential for life, and having access to water beyond Earth will be a major obstacle for future ...
Rocks on Mars may provide link to evidence of living organisms 4 billion years ago
A new article in press of the journal Earth and Planetary Science Letters unveils groundbreaking research on the hydrothermal formation of Clay-Carbonate rocks in the Nili Fossae region of Mars. The findin ...
