The next trick, which Exxon's money will help pay for, is to tweak the biochemical pathway that makes the algal oil (which is known, technically, as a triglyceride, and has oxygen atoms in it as well as carbon and hydrogen) so that the oxygen-containing parts of the molecules are snipped off and a pure hydrocarbon is left.
The researchers expected to see a build-up of lactic acid and an acidic environment in the brain, as seen in other organs suffering from oxygen deprivation.
And because the bacteria use oxygen in the water as they digest oil, scientists are concerned that process could cause an oxygen-depleted area underwater a "dead zone" that could choke off a variety of undersea life.
Just as every school child knows that water is formed by the two elements of hydrogen and oxygen in a very simple combination we all know as H2O, so deflation has its own elements of composition.
Obesity causes impairments in lung function, such as a reduction in lung volume and an increase in the amount of oxygen used during breathing, but these on its own would not be enough to induce the condition.
As they desperately try to breathe and pull in more oxygen, they may inhale too much salt water into their lungs and drown.
Although jets are pressurized so that the cabin environment resembles an altitude of around 8, 000 feet, some people report that flying (possibly from the changes in pressure and resulting decrease in oxygen concentration) causes symptoms such as headache, fatigue and nausea.
As in those African economies, it is the banks that provide the oxygen to sustain growth.
The Ariane's core stage, which is prepared in northern France, uses liquid hydrogen and liquid oxygen as its propellants.
That means each of its molecules contains an oxygen atom as well as the carbon and hydrogen found in an alkane.
ECONOMIST: Biofuels are back. This time they might even work
As the body notices that it needs oxygen, it tries to take in a large amount of air, causing a gasping, snoring or snorting sound.
To find out how warm the earth was before that, climatologists have had to resort to indirect methods, such as measuring tree-rings, or counting the different isotopes of oxygen in layers of polar ice.
The lack of progress has led a number of Baltic countries to consider technological interventions, or so-called "geoengineering" ideas (large-scale solutions to environmental problems), such as pumping oxygen into the water, and using chemicals to bind pollutants in sediments, in a bid to save the Baltic.
The lander Moon Express showed off Thursday is powered by compressed oxygen, for now, as Moon Express employees test it at a NASA facility in Mountain View, California.
FORBES: Naveen Jain: 'Think Of The Moon As Just Another Continent'
Air Products sells gasses like nitrogen, hydrogen, oxygen and helium used in industrial and medical capacities, while Airgas sells gasses as well as wielding products and safety equipment.
The prize will go to the first person to come up with a way of quickly extracting an adequate amount of oxygen from simulated lunar regolith (volcanic ash is being used as a stand-in).
She had no firsthand knowledge of what it was like to feel your breath being squeezed off, to live in a world whose very atmosphere was a constant taunt, whose bountiful oxygen was as capriciously out of reach as a rainbow.
That can be characterized by sort of an acute respiratory distress, such as difficulty in breathing, sweating, high temperature, and turning blue, basically, from lack of oxygen.
Their scientists know that the only significant effect of increased CO2 in the atmosphere has been to improve global agricultural output, as CO2 is plant food, or oxygen to plants.
FORBES: President Obama's State Of Disunion: Half of America Is In a Trance
Among other things, she does foresee a future in which the top 10 cable networks (think USA, as opposed to niche cable outlets like Oxygen) have developed an intra-cable syndication market for shows they can then sell to smaller networks.
As the bacteria produced oxygen, the two compounds reacted to form iron oxide, which precipitated onto the seafloor in great layers of rust.
Low oxygen (hypoxic) areas known as dead zones, where most marine life cannot survive, can result in the collapse of some ecosystems.
As a result, it is bombarded by the solar wind and this might have resulted in the loss of water and oxygen.
In 96 tiny wells robotic arms mixed variations of molecules containing nitrogen, oxygen and sulphur with metals such as zirconium, titanium and hafnium.
FORBES: Upstart Symyx is shaking up the stodgy chemicals industry.
