A newborn is triggered into its first breathe by contractions that reducing oxygen flow through the umbilical, which increases carbon dioxide. The increase of carbon dioxide causes acidosis which triggers the respiratory center of the brain, causing the baby to start using it's lungs. courses.lumenlearning.com…
Bogs are Ireland’s original refrigerators. And they are pretty goodβ€”even 3,000-year-old bog butter is edible. We know this because archeologists tended to eat it. The secret is the anaerobic nature of the bog. Without oxygen, neither the butter nor its wooden container decomposes. daily.jstor.org/irelands-…
Viagra is given to some premature babies to increase oxygen transport by widening the blood vessels, as their lungs often haven't developed enough to transport oxygen efficiently on their own moneyinc.com/20-things-yo…
The β€œDeath Zone” is what climbers call the highest part of Mount Everest (everything above 26,247ft). Due to its lack of oxygen, the body literally begins to die, cell by cell. This can result in health risks like impaired judgement, heart attack or stroke, and altitude sickness. businessinsider.com/mount…

Scientists made 5 trained subjects exercise at intensities of 25, 65, and 85% of maximal oxygen consumption. They found that while at 65%, fat utilization increased, at 85% it decreased again and was similar to utilization at 25%. At 85% their bodies relied mostly on carbohydrate to produce ATP. sciencedrivennutrition.co…

The emergency oxygen on airplanes comes from a burning chemical reaction, not compressed gas. en.wikipedia.org/wiki/Eme…
The blue whale heart rate was measured for the first time last year! It gets as low as 2 beats per minute, raising up to 37 when it resurfaces (more oxygen access). It works at physiological extremes, and explains why the whale never evolved to be even bigger. newatlas.com/biology/firs…
A 16 year old survived a five hour flight inside the landing gear of a jumbo jet from San Jose, California to Maui, Hawaii. He blacked out on takeoff and the plane went to 38,000ft meaning temperatures of 75-80 below zero and a lack of oxygen probably leading to "a state of suspended animation." cnn.com/2014/04/21/us/haw…
In about 600 million years, due to increased luminosity from the sun, all C3 photosynthesis will end and the vast majority of plant life (99% of present day species) will die as a result. This will further result in severely depleted oxygen levels and the end of life complex life on Earth. en.wikipedia.org/wiki/Tim…
Almost all life on earth was destroyed around 2.4 billion years ago in the Oxygen Catastrophe (aka Great Oxidation Event). Photosynthesizing microorganisms pumped massive amounts of oxygen into the previously oxygen-poor atmosphere, making it oxygen rich. Most species perished, new ones arose. en.wikipedia.org/wiki/Gre…

Trees are mostly made from the air, not the ground. They take carbon dioxide, use photosynthesis to split carbon off to make most of their mass, and "exhale" the oxygen. youtu.be/ifk6iuLQk28
The upper-layer skin cells and the cells in the front surface of the eyes get a significant amount of oxygen directly from the air rather than from the blood. wtamu.edu/~cbaird/sq/mobi…
50 to 85 percent of oxygen on Earth comes from the ocean, mainly from phytoplankton. earthsky.org/earth/how-mu…

Doctors are able to inject oxygen into patients bloodstreams. nature.com/articles/s4159…
What causes the β€œlump” in your throat when you cry. The autonomic nervous system responds to all types of crying as stress. In turn, this opens the glottis to allow more oxygen into the lungs. When we swallow, the glottis must close, creating the β€œlump”. indianapublicmedia.org/am…
The West African lungfish can survive up to 3.5 years without food or water. It has been around for 400 million years & their gills have evolved to obtain oxygen from the air as well as water. During estivation they get nutrients by digests its muscle tissue & can go on for years! worldatlas.com/articles/w…

Why the cut apple turns brown. It turns out that the enzymes and polyphenols in the apple react with oxygen; now some apples on the market will not change color because they have been genetically modified. todayhealthonline.com/sci…
The WW2 Luftwaffe Dormier Do 17 bomber had a flamethrower installed in the rear. Due to insufficient oxygen mix, it never worked, and only shot oil. en.wikipedia.org/wiki/Ope…
The wonderful smell that happens after a rain shower is not one, but three distinct smells: ozone caused by lightning ripping through oxygen and nitrogen in the atmosphere, spores produced by common ground bacteria, and oils produced by plants during dry spells as an evolutionary safeguard. gizmodo.com/what-causes-t…
Most Samsung phones from the past 5 generations have sensors built-in to read your pulse and oxygen levels androidcentral.com/how-me…
Some lungfish need air to respire and their gills don't provide enough oxygen encyclopedia.com/plants-a…
Saturation Divers have to breathe a helium oxygen mix since a Nitrogen oxygen mix can lead to Nitrous Oxide poisoning. Due to this divers have high pitched helium voices for their entire submersion period which leads to more difficulty in communicating. youtu.be/Bmy8hqYvEyw

The 1996 crash of ValuJet Flight Flight 592 was caused by a "perfect storm" of various employees routinely signing off on mundane tasks, from the subcontractors who didn't properly package expired oxygen generators to the co-pilot who allowed them to be loaded in a forward cargo hold. mentalfloss.com/article/2…
Today I learned of 'elysis', a new smelting process for aluminum that releases oxygen instead of carbon dioxide. This new production process both cuts operating costs by 15% and increases production by 15%. Apple has invested $11 million in the venture behind it and is offering technical support. greentechmedia.com/articl…
