In hot springs and undersea vents, simple carbon compounds bubbled up to form amino acids and peptides.
By measuring the carbon compounds spewed out during the test, automakers can figure out how much fuel was spent and, subsequently, the vehicle's fuel economy.
Metals, platinum-group elements, rare earth elements, and other volatiles, like H, H2O, and carbon compounds, are abundant on asteroids, many of which are relatively accessible from Earth.
Nitrogen, methane, helium, water, carbon-oxygen compounds and hydrogen produced from mining, could permit food growth and development of a water supply for lunar inhabitants.
Based on these findings, Dr Jiao and his colleagues propose that AAPB, and possibly other, similar microbes, have a predominant role in pumping carbon into a pool of compounds that cannot be turned back into carbon dioxide by living creatures, thereby building up a large reservoir that keeps carbon out of the atmosphere.
The pollutants that the scientists focused on were compounds containing carbon and halogens - fluorine, chlorine, bromine or iodine.
In a briefing, Nasa scientists announced that Curiosity had detected organic compounds - complex molecules containing carbon, without which no known life can develop.
It is from a class known as the carbonaceous chondrites - primitive, carbon-rich meteorites that contain organic compounds such as amino acids.
These include the exhaust gases such as nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOCs), and carbon monoxide (CO).
UTC's solution: Pass the return air through an aluminum filter sprayed with titanium dioxide that, hit with ultraviolet rays, sets off a chemical reaction that breaks down nasty organic compounds like benzene and formaldehyde into carbon dioxide and water.
The latter include health-damaging and smog-forming airborne pollutants like hydrocarbons, nitrogen oxide, particulate matter, carbon monoxide and formaldehyde, as well as greenhouse gases that contribute to climate change, like carbon dioxide, nitrous oxide, methane and other compounds.
