The test, which could be available to patients within two years, identifies the chemical signatures found in the plasma of blood joint proteins damaged by oxidation, nitration and glycation; the modification of proteins with oxygen, nitrogen and sugar molecules.

The findings: carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorous — key ingredients for life — plus chemicals such as sulfur dioxide and hydrogen sulfide that could provide energy for microorganisms.

The researchers tested a variety of solutions containing the soil bacteria Geobacter sulfurreducens and Thiobacillus denitrificans, which thrive by eating acetate (an organic compound that makes vinegar sour) and nitrate (a negatively - charged molecule of biologically available nitrogen and oxygen), respectively, when they can find a spare electron or two.

The near - infrared mapping spectrometer on NASA's Galileo spacecraft found evidence of the presence of molecules made of oxygen, carbon, sulfur, hydrogen, and nitrogen on Europa, and a hint of the presence of a class of complex organic compounds called tholins which may be driven by pre-biotic processes (more).

Other abundance anomalies are found in a peculiar class of higher temperature stars, called Wolf - Rayet (or W) stars, in which objects containing predominantly helium, carbon, and oxygen are distinguished from those containing helium and nitrogen, some carbon, and little observed oxygen.

Up to 80 % of the available oxygen, carbon and nitrogen are found in such ices; the most common ice constituents - H2O, CO2 and CO - are second in abundance only to H2 in many star forming regions.

The gas is only found in trace amounts in Earth's atmosphere (which is mostly made up of nitrogen and oxygen), even though carbon is the primary basis for life on our planet.

He ticked off several of the ingredients necessary for life that have been found on Enceladus, including water and key elements such as carbon, hydrogen, nitrogen and oxygen.

This knowledge is not new; the same year as Charles Darwin published «The Origin of Species», John Tyndall, an Irish scientist, published a paper in 1859 describing how he measured the absorption of infrared radiation in his laboratory, finding that CO2 and water vapour absorbed the radiation, whereas nitrogen and oxygen, the main gases in the atmosphere, do not.

Oxygen, in combination with hydrogen, is found in water and in many other compounds: so is carbon, nitrogen and sulphur, the elements from which proteins and other cellular components are made.

I found one online discussion, (but haven't checked for reliability of their numbers) that indicated the temperature of the earth without the sun would be about 30 degrees kelvin, cold enough for oxygen and nitrogen to freeze out.

He found that gases and vapors whose molecules had three or more atoms, such as water vapor and CO2, absorbed much more of the thermal radiation passing through the tube than did two - atom molecules such as oxygen and nitrogen.

I'm sure you will also find that this lapse rate would be the same for an 80 % pure nitrogen and 20 % pure oxygen atmosphere, because such lapse rate is a function of the acceleration due to gravity.

Nitrogen oxides are formed when oxygen and nitrogen come together at high pressure and temperature found in the internal combustion engine.

However, when measuring the isotopes in nitrate alone, the team found an unexpected imbalance in the ratio of heavy nitrogen and oxygen.
