- Lungs and Respiration (Franklin Institute)
"The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood." 10-09
- Aeroponics (Wikipedia.org)
"The basic principle of aeroponic growing is to grow plants in a closed or semi-closed environment by spraying the plant's roots with a nutrient rich solution. Ideally, the environment is kept free from pests and disease so that the plants may grow healthier and quicker than plants grown in a medium. However, since most aeroponic environments are not perfectly closed off to the outside, pests and disease may still cause a threat. These conditions advance plant development, health, growth, flowering and fruiting for any given plant species and cultivars. Oxygen in the rhizosphere (root zone) is necessary for healthy plant growth. As aeroponics is conducted in air combined with micro-droplets of water, almost any plant can grow to maturity in air with a plentiful supply of oxygen, water and nutrients."
- Tree Planting (American Forests)
Provides information on tree planting. Research suggests that urban areas need at least 40 percent coverage of trees for good quality of life. Trees reduce pollution, keep water in the soil, provide oxygen to the air, and provide shade from the sun during the summer to reduce air conditioning costs. 9-01

- -Editorial - Terrorists Require the Partnership of Mass Media (Christian Science Monitor - Felling)
"Troubling questions abound: Does terrorism exist without the media? Does coverage of terrorist acts empower or encourage the people behind them? If terrorism is directed more at the audience than at its victims, shouldn't television journalists stop giving terrorists the forum they covet?"
"Certainly, television news covers terrorist attacks for the high-minded journalistic objective of informing viewers. But the zeal with which fear has been commoditized - from shark attacks to child kidnappings to the Washington sniper - is a product of TV executives realizing that frightened people put down the remote control and await news updates, ratcheting up ratings points. Unfortunately, this living-room fearmongering plays right into the hands of terrorists who are attempting to rattle every American, turning television news reporters into de facto publicists for terrorists."
"Nearly 20 years ago, the eminent Washington reporter David Broder suggested that 'the essential ingredient of any effective antiterrorist policy must be the denial to the terrorist of access to mass media outlets.' He said this in a different era, before 24-hour news channels were in hot competition for Americans' attention. He's still right."
"Amateur cooks learn quickly that pouring water on a grease fire only makes it worse. Broadcasters must realize that their coverage might be doing the same. Like cutting off the oxygen that sustains a flame, a few internal shifts in reporting policy would traumatize viewers less and could save lives." 9-04
- Terraforming Mars - Short Description (NASA - Quest)
"First, greenhouse gases, like chlorofluorocarbons that contribute to the growing ozone layer on Earth, will be released into the atmosphere. This traps the heat from the Sun and raises the surface temperature by an average of 4 degrees Celsius."
"The increasing temperature would vaporize some of the carbon dioxide in the south polar cap. Introducing carbon dioxide into the atmosphere would produce additional warming, melting more of the polar cap until it has been vaporized completely. This would produce an average temperature rise of 70 degrees Celsius."
"With the temperature this high, ice will start melting, providing the water needed to sustain life. This water would raise the atmospheric pressure to the equivalent of some mountaintops. While this would be a survivable level, it may still require the use of an oxygen mask. The next step, which may take up to several centuries, would be to plant trees that thrive on carbon dioxide and produce oxygen." 02-06
- -03-18-06 Iraq Three Years Later (MSNBC News)
"When I first arrived in Baghdad before the war, Iraq seemed lifeless. Baghdad felt like a city without oxygen, where those with big dreams couldn’t breathe or imagine a better life. Now, the country is very changed — in some ways for the better (as you'll see in the chart below) — but it has become equally menacing, terrifying and sinister." 3-06
- -06-16-06 Fish Control Mosquitoes (CNN News)
"The mosquito fish, native to this region and probably the world's most effective biological mosquito control agent, are surface-breathers and capable of surviving in polluted waters with low oxygen levels. Their primary food source is mosquito larvae, though they also can live off algae." 06-06
- Teen Choking Game Has Fatal Consequences (ABC News)
"In the choking game, also known as the flatliner or the pass-out game, adolescents attempt to experience a quick high — a high that lasts only a second — by strangling themselves. Kids commonly use belts, ropes, towels or their own hands to cut off oxygen. If the kids hold on for too long their organs begin to shut down or they are strangled to death. Some kids have reported experiencing seizures when they play.'' 06-06
- Plant the Right Trees for Better Carbon Sequestration (ABC News)
""Syracuse researchers found that if they could replant their city with trees that are great at sequestering carbon compounds, especially carbon dioxide, they could increase the removal of carbon by more than 300 percent. But they also found that air quality would actually suffer from an increase in volatile compounds."
"So they looked at mixing the forest, emphasizing trees that are good performers when it comes to carbon sequestration and don't emit a lot of junk. They came up with a list of 31 species, including American basswood, dogwood, Eastern white pine, Eastern red cedar, gray birch, red maple and river birch. That combination, they found, would increase carbon sequestration by 86 percent, and reduce the emission of volatile compounds by 88 percent."
Editor's Note: Trees also increase oxygen in the air, of course. 02-07
- Tips for Avoiding Bad Breath (CBS News)
"Dr. Harold Katz, a dentist, is the founder of California Breath Clinics, and the international guru of good breath. He came to The Early Show to tell people how they can keep their mouths smelling good."
"Katz said that alcohol, detergent and toothpaste dry out the mouth which adds to bad breath. Even sugar in breath mints feed bacteria to make bad breath worse. The best way to fight bad breath, Katz said, is to oxygenate the mouth."
" 'These are available in drugstores, discounted stores, supermarkets and online stores,' he said gesturing to some products he brought on to the show." 03-07
- Pond Plants (TheRealMcKoi.co.uk)
"Submerged oxygenating plants should be considered essential in most ponds as they absorb many chemicals from the water, such as metallic salts. As ordinary tap water contains such substances it is a good idea to have several bunches in your pond. This will go a long way towards taking the hard edge from tap water." 08-07
- Gamma-Ray Bursts (Wikipedia.org)
"Gamma-ray bursts (GRBs) are the most luminous events known in the universe since the Big Bang. They are flashes of gamma rays coming from seemingly random places in deep space at random times. GRBs last from milliseconds to many minutes, and are often followed by 'afterglow' emission at longer wavelengths (X-ray, UV, optical, IR, and radio). Gamma-ray bursts are detected by orbiting satellites about two to three times a week, as of 2007, though their actual rate of occurrence is much higher."
"One line of research has investigated the consequences of Earth being hit by a beam of gamma rays from a nearby (about 500 light years) gamma ray burst. This is motivated by the efforts to explain mass extinctions on Earth and estimate the probability of extraterrestrial life. The consensus seems to be that the damage that a gamma ray burst could do would be limited by its very short duration, and the fact that it would only cover half the Earth (the other half would be in its shadow). A sufficiently close gamma ray burst could do serious damage to atmospheric chemistry, perhaps instantly wiping out half the ozone layer, and causing nitrogen-oxygen recombination, generating acidic nitrogen oxides. These effects would diffuse across to the other side of the Earth and result in long-term climate and atmospheric changes, resulting in a mass extinction. The damage from a gamma ray burst would probably be significantly greater than a supernova at the same distance." 10-07
- -10-09-07 Blood Transfusions May Cause Heart Disease (Time.com)
"Logically, and medically, patients who need transfusions — those with low blood counts — should benefit immediately from a transfusion of new oxygen-laden red blood cells. Yet many get sicker. Puzzled by the paradox, Stamler and his colleagues decided to look more closely at banked blood — to figure out whether it underwent certain changes that turned it from life-saving in the donor to potentially deadly in the bag."
"Their finding, reported this week in the Proceedings of the National Academy of Sciences: nitric oxide (NO). A workhorse of the blood, the gas helps red blood cells ferry oxygen to tissues and props open tiny vessels to allow freer blood flow. It turns out that within hours of leaving the body, levels of nitric oxide in the blood begin to drop, until, by the time donated blood expires after 42 days, the gas is almost nonexistent. 'The reality is that we are giving blood that cannot deliver oxygen properly,' says Stamler, lead author of the study. 'Many patients who are getting blood are being put at increased risk.' " 10-07
- Biosand Filters (BiosandFilter.org)
"In order to be effective, most literature insists that a constant flow of water passing through a slow sand filter is essential. This flow provides oxygen and food to the organisms that make up the 'schmutzdecke' and biological zone living within the top part of the sand, which are responsible for much of the removal of disease-causing organisms. Under stagnant conditions, the biological can start to die - sometimes within several hours."
"However, Dr. Manz of the University of Calgary re-designed the traditional sand filter, making it suitable for intermittent use at a household level. This adaptation, brilliant in simplicity, consists of raising the under drain pipe back up to between 1 and 8 cm above the sand level, ensuring a foolproof method for maintaining the water level just above the sand. Manz proved that, even when water is not continually added to the filter, oxygen can still permeate into the water to reach the organisms living in the sand by diffusion accross this shallow layer of standing water." 10-07
- Biogeochemical Evolution (Chem1.com)
"Oxygen is poisonous to all forms of life in the absence of enzymes that can reduce the highly reactive byproducts of oxidation and oxidative metabolism (peroxides, superoxides, etc.). All organic compounds are thermodynamically unstable in the presence of oxygen; carbon-carbon double bonds in lipids are subject to rapid attack. Prebiotic chemical evolution leading to the development of biopolymers was possible only under the reducing, anoxic conditions of the primitive atmosphere." 11-07
- Fertilizers Creating a Huge "Dead Zone" in the Gulf (MSNBC News)
"The nation's corn crop is fertilized with millions of pounds of nitrogen-based fertilizer. And when that nitrogen runs off fields in Corn Belt states, it makes its way to the Mississippi River and eventually pours into the Gulf, where it contributes to a growing "dead zone" — a 7,900-square-mile patch so depleted of oxygen that fish, crabs and shrimp suffocate." 12-07
- Extinction Level Event: End Permian (ScienceDaily.com)
"In the end-Permian, as the levels of atmospheric oxygen fell and the levels of hydrogen sulfide and carbon dioxide rose, the upper levels of the oceans could have become rich in hydrogen sulfide catastrophically. This would kill most of the oceanic plants and animals. The hydrogen sulfide dispersing in the atmosphere would kill most terrestrial life." 12-07
- Algae for Natural Carbon Sequestration (ScienceDaily.com)
"Engineers have designed a simple, sustainable and natural carbon sequestration solution using algae."
"Bayless, with a team at Ohio University, created a photo bioreactor that uses photosynthesis to grow algae just like a plant would take carbon dioxide up and, through the energy of the sun, convert that into oxygen."
"But what makes it cost effective? The algae can be harvested and made into biodiesel fuel and feed for animals." 06-08

- Biochar for Long-Term Carbon Sequestration (Guardian.co.uk)
"Biochar is a type of charcoal produced by heating crop wastes, wood or other biomass in a simple kiln designed to limit the presence of oxygen. This process, known as pyrolysis, creates rather than consumes energy, as more combustible gases are released than are needed to heat up the kiln."
"Biochar is made largely of carbon, which the crops or trees previously sucked out of the air in the form of CO2. Unlike crop wastes and wood, it's an extremely stable substance, which if mixed into soil will safely lock up its carbon content for hundreds or even thousands of years – a biological form of carbon capture and storage."
"If biochar is mixed with poor-quality tropical soils, it has an important added benefit: it can significantly boost crop productivity, reduce nitrous oxide and methane emissions and improve soil structures." 08-09
- -Dietary Solutions to Methane from Cattle (Time.com)
"Most dietary interventions work by checking methogens — microbes that thrive in oxygen-free environments such as cows' guts, where they convert the available hydrogen and carbon (byproducts of digestion) into methane, a colorless, odorless gas. 'We encourage well-to-do farmers to use oilseed cakes which provide unsaturated fatty acids that get rid of the hydrogen,' Dr. Singhal says. Another solution is herbal additives. Some commonly used Indian herbs such as shikakai and reetha, which go into making soap, and many kinds of oilseeds contain saponins and tannins, substances that make for lathery, bitter meals but block hydrogen availability for methogens. Dr Singhal says they are used in small quantities and the cows don't seem to mind the taste. 'Imagine how much potential they'd have in the international market,' he says." 04-09
- What Is Biochar? (BioCharBrokers.com)
"Biochar is a charcoal product that is created as result of either Pyrolysis or Gasification. Simply put, biochar is created from a low- to no-oxygen burn (thermal conversion) of feedstock or biomass under intense pressure, returning it to carbon."
EternaGreen sells 50-pound bags of biochar for $12.50. Awesome Library does not endorse the products but provides them as examples. 05-09
- -001 Lovelock: One Last Chance to Save Mankind (NewScientist.com)
"There is one way we could save ourselves and that is through the massive burial of charcoal. It would mean farmers turning all their agricultural waste - which contains carbon that the plants have spent the summer sequestering - into non-biodegradable charcoal, and burying it in the soil. Then you can start shifting really hefty quantities of carbon out of the system and pull the CO2 down quite fast."
"Would it make enough of a difference?"
"Yes. The biosphere pumps out 550 gigatonnes of carbon yearly; we put in only 30 gigatonnes. Ninety-nine per cent of the carbon that is fixed by plants is released back into the atmosphere within a year or so by consumers like bacteria, nematodes and worms. What we can do is cheat those consumers by getting farmers to burn their crop waste at very low oxygen levels to turn it into charcoal, which the farmer then ploughs into the field. A little CO2 is released but the bulk of it gets converted to carbon. You get a few per cent of biofuel as a by-product of the combustion process, which the farmer can sell. This scheme would need no subsidy: the farmer would make a profit. This is the one thing we can do that will make a difference, but I bet they won't do it." 05-09
- Gasification (OrganicEnergy.ca)
"In contrast to incineration, where fuel is burned under high temperatures to produce heat energy, gasification converts the hydrocarbons in solid fuels under controlled temperature and oxygen conditions to produce viable fuel known as syngas."
"Gasification removes pollutants from feedstock in an efficient manner. By contrast, the combustion process of incinerators produces pollutants that must be removed through costly filtering and pollution control systems." 05-09
- Deepest Ocean Dive (Wikipedia.org)
"In the Trieste the pressure sphere provided just enough room for two people. It provided completely independent life support, with a closed-circuit rebreather system similar to that used in modern spacecraft and spacesuits: oxygen was provided from pressure cylinders, and carbon dioxide was scrubbed from breathing air by being passed through canisters of soda-lime. Power was provided by batteries." 08-09
- Biochar Kilns: How They Work (Biochar-International.org)
"PYROLYSIS systems produce biochar by baking biomass largely in the absence of oxygen. The process can become self-sustaining as the syngas produced is combusted, releasing heat. There are two types of pyrolysis systems in use today: fast pyrolysis and slow pyrolysis. Fast pyrolysis tends to produce more oils and liquids while slow pyrolysis produces more syngas. Biochar production is optimized in the absence of oxygen." 08-09
- Biochar Kilns: Diagrams (Biochar-International.org)
"Pyrolysis systems use kilns and retorts and other specialized equipment to contain the baking biomass while excluding oxygen. The reaction vessel is vented, to allow pyrolysis gases to escape. Pyrolysis gases are often called 'syngas'. The process becomes self-sustaining as the syngas produced is combusted, and heat is released."
"There are two types of pyrolysis systems in use today: fast pyrolysis and slow pyrolysis. Fast pyrolysis tends to produce more oils and liquids while slow pyrolysis produces more syngas." 09-09
- -10-15-09 Gas May Be a Lifesaver (CNN News)
"The air we breathe is 21 percent oxygen. At 5 percent, those fish and flies -- like us -- would be dead in a few minutes. At 0.1 percent, it was another story. 'You get a state of suspended animation and the creatures do not pass away, and that's the basis of what we see as an alternative way to think about critical care medicine,' Roth says. 'What you want to do is to have the patient's time slowed down, while everyone around them [like doctors] move at what we would call real time.' "
"If the patient's time -- the process of your death -- were slowed down, doctors would have more time to fix you. In medicine, time is key. An analogy is the history of open heart surgery. For years, surgeons had the technical tools to make simple repairs on the heart, but they couldn't help patients until the development of the heart-lung machine made it possible to preserve the body for more than a few minutes without a heartbeat." 10-09
- -11-19-09 We Could Be Hitting the Limit of Oceans to Absorb CO2 (Time.com)
"Like the vast forests of the world, which continually suck carbon dioxide from the atmosphere and release oxygen, the planet's oceans serve as vital carbon sinks. Last year the oceans absorbed as much as 2.3 billion tons of carbon, or about one-fourth of all manmade carbon emissions. Without the action of the oceans, the CO2 we emit into the atmosphere would have flame-broiled the planet by now."
"But a new paper published in the Nov. 19 issue of Nature demonstrates that the oceans' ability to absorb man-made carbon may be dwindling — and that has worrying ramifications for future climate change. While the ocean is now absorbing more carbon in total than ever before, the waters are sucking up a smaller percentage of the CO2 emitted by humans. That could mean that there's a physical limit to the oceans' capacity — and we could be hitting it." 11-09
- -12-03-09 Comcast to Take Over NBC (USA Today)
"Comcast and General Electric said Thursday that they finally have a deal."
"They agreed to forge a joint venture that will give Comcast, the No. 1 cable operator, control of programming giant NBC Universal, creating the largest entertainment company in the United States."
"The deal, which values NBC Universal at $30 billion, will make Comcast (CMCSA) a major power in television and movie production, theme parks, and the Internet. NBC Universal's channels include the NBC TV network, Telemundo, USA Network, Bravo, CNBC, MSNBC, and Oxygen. The company also is a founder of Hulu, the No. 2 site for Web videos after Google's YouTube." 12-09
- -03-22-05 Terri Shiavo: "Vegetative State" Defined by Neurologists (ABC News)
"Doctors have determined that Schiavo is in a persistently vegetative state. Bernat explains this is when 'you have wakefulness, your eyes are open, but you are unaware. It can appear as if you are aware, but it's a state of unconsciousness.' "
"How can a patient be awake but unaware? Bernat says extensive damage to key parts of the brain — namely, the cerebral cortex, the thalamus and/or connections between them — can strip a person of his or her sense of awareness, while an undamaged brain stem keeps automatic activities, such as breathing, sleep and wake cycles and eye movement, going."
"Ronald Cranford, a neurology professor at the University of Minnesota Medical School who has examined Schiavo, says there are a number of signs showing that her cerebral cortex has severe damage from the six-minute period in 1990 when her heart stopped and her brain was without oxygen. He said electroencephalograms, also known as EEGs or brain wave tests, of Schiavo's brain have revealed no activity. He has also reported that areas of her brain have shown shrinkage — a sign of irreversible damage."
"David Gibbs, the attorney for Schiavo's parents, who wish to keep her on life support, has argued that Schiavo may be in a semiconscious state known as a minimally conscious state. This state of consciousness was first defined in 1996 as a transitional state indicating either improvement in consciousness or deterioration in the level of consciousness."
"An estimated 100,000 to 300,000 Americans have been diagnosed with being in this transitional state and some patients have emerged from the condition to reach a fuller consciousness. But neurologists are quick to point out that there are important distinctions between those in a semiconscious state and those in a persistently vegetative state."
" 'The difference is between autonomic activity and episodic conscious activity,' said Fins. 'It's something that can be observed by a neurologist or detected on a brain scan. It's not a diagnosis that legislators can make after viewing videotapes.' " 03-05.
- Double-Bedding Preemies (Daurelia.com)
"Nurse Gayle Kasparian tried everything she could think of to stabilize Brielle. She suctioned her breathing passages and turned up the oxygen flow to the incubator. Still Brielle squirmed and fussed as her oxygen intake plummeted and her heart rate soared."
" 'Let me just try putting Brielle in with her sister to see if that helps,' she said to the alarmed parents. 'I don't know what else to do.' "
"No sooner had the door of the incubator closed then Brielle snuggled up to Kyrie - and calmed right down. Within minutes Brielle's blood-oxygen readings were the best they had been since she was born. As she dozed, Kyrie wrapped her tiny arm around her smaller sibling." Provides a picture of the hug. 9-05.
- -03-21-08 Sleep Apnea Home Test Now Available (US News)
"Overnight sleep tests in a lab, or polysomnography, generally collect 12 "channels" of information, including blood oxygen levels, nasal and oral airflow, and electrical information. A home test need only include three such channels of information. You might wear monitors while you sleep that measure airflow and breathing patterns, for example, and a gadget on your fingertip that indicates the level of oxygen in your blood. And sleep specialists have experience finding the meaning in sleep study data. Now, people who test at home might well take the results to their own physician." 03-08
- Arteriosclerosis: Hardening of the Arteries (eMedicineHealth.com)
"Hardening of the arteries (arthrosclerosis) is a disorder in which arteries (blood vessels that carry oxygenated blood from the heart to other parts of the body) become narrowed because fat (cholesterol deposits called atherosclerosis) is first deposited on the inside walls of the arteries, then becomes hardened by fibrous tissue and calcification (arteriosclerosis). As this plaque grows, it narrows the lumen of the artery (the space in the artery tubes), thereby reducing both the oxygen and blood supply to the affected organ (like the heart, eyes, kidney, legs, gut, or the brain). The plaque may eventually severely block the artery, causing death of the tissue supplied by the artery, for example, heart attack or stroke." 12-09
- Dangerous Sealer Grout Recalled (CNN News)
"Friedel said doctors told him a chemical in Stand 'n Seal had severely damaged 30 percent of his lungs. They said he had "chemical pneumonia" and put him in intensive care for four days. Friedel needed an oxygen tank for four months. He still struggles to walk up long flights of stairs or hills without shortness of breath, he said."
"What Friedel didn't know before using the tile grout sealer was that it had been recalled by the Consumer Product Safety Commission two months earlier. News reports at the time said the product had made dozens of people sick and killed two of them." 10-07
