, aroundf 2.1 billion years ago, there existeed several multicellular organisms, that were likely one of the first forays into multicellularity, they coincided with a brief moment of increased oxygen levels and went extinct after the levels dropped, they do not have any modern-day descendants. en.wikipedia.org/wiki/Fra…
James Franco once created an invisible sculpture called 'Fresh Air'. It was described as an endless supply of oxygen. Someone actually bought the 'sculpture' for $10,000 npr.org/sections/thetwo-w…
The blue planet used to be purple. 250 million years ago, the oceans lost all their oxygen and one of the only things to survive was a purple alga/bacteria which would have given the seas an irridescent violet hue. Geologists have found remnants of this purple bacteria embedded in ancient rock. astrobio.net/biosphere/di…
Children have more energy than endurance athletes. They have fatigue-resistant muscles and they recover faster than adults. Much of this stems from their ability to uptake and distribute oxygen, as well as synergize energy faster. frontiersin.org/articles/…
Stevie Wonder wasn't actually born blind, but became so at six weeks old due to the incubator he was placed in after birth containing too much oxygen and causing the condition Retinopathy of Prematurity. smoothradio.com/artists/s…
The red liquid seeping out of a cooked rare steak isn't blood. It is in fact a mixture of a protein called 'Myoglobin' and water. Myoglobin helps muscle tissue store oxygen and just like Hemoglobin, contains iron that turns red when it binds with oxygen. thehealthy.com/food/is-me…
The Gulf of Mexico has a dead zone: an area of hypoxic (less than 2 ppm dissolved oxygen) waters, which supports fewer organisms and has been linked to massive fish kills and can cover up to 6,000-7,000 square miles (9656-11265 square kilometers) at the mouth of the Mississippi River serc.carleton.edu/microbe…

"Pistol" Pete Maravich, the greatest college basketball scorer of all time, and NBA all-star, was born with one coronary artery, while the rest of us have two. He died while playing a pickup basketball game at age 40. At death his heart was scarred and enlarged from oxygen deprivation. pediatricheartspecialists…
Today I learned about microorganisms called Obligate Anaerobes. They cannot survive in normal oxygen concentrations, 20.95%. Some can only survive in 8% oxygen concentration whereas others can only tolerate 0.5% oxygen concentration. en.wikipedia.org/wiki/Obl…
Today I learned of Valentin Bondarenko, the first soviet cosmonaut to die. He suffered severe burn injuries from an accidental fire caused by throwing an alcohol-doused cotton ball on a hot plate inside an oxygen-rich isolation chamber after a 15 day experiment, just 3 weeks prior to Gagarin’s space flight. military.wikia.org/wiki/V…
Today I learned about chlorine triflouride, a better oxidiser than Oxygen. It can set fire to things that are normally not flammable such as concrete, glass, flesh, sand, steel, asbestos, and ash. It is also extremely corrosive and will corrode things like Gold, Iridium, and Platinum. en.wikipedia.org/wiki/Chl…
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…
Predatory dragonflies the size of modern seagulls were present on the earth about 300 million years ago. The leading theory suggests that their large size was due to high oxygen concentrations (over 30% unlike the 21% today) in the atmosphere. news.ucsc.edu/2012/06/gia…
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-…
Aluminum is so corrosion resistant because where iron and steel rust, Al combines with oxygen to form a material even harder than aluminum itself, called corundum. This is the second hardest naturally occurring material, next to diamond. en.wikipedia.org/wiki/Alu…
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…
One difference between Earth and Mars is that the latter's atmosphere has a lower escape velocity, i.e. molecules can escape it more easily. Earth loses 3 kg/s of hydrogen, 50 g/s of helium, and only traces of other elements. By comparison, Mars loses over 1000 g/s of both oxygen and hydrogen faculty.washington.edu/dc…
While many believe that earth's oxygen comes from rainforests, tiny ocean plants called phytoplankton contribute 50-80% of the oxygen on earth earthsky.org/earth/how-mu…
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…
Today I learned about Deep Hypothermic Circulatory Arrest (DHCA), wherein patients are deliberately put into hypothermia as low as 20C (68F) thereby stopping all heart and brain function in order to increase survival time on reduced oxygen, while making delicate surgeries easier. en.wikipedia.org/wiki/Dee…
The Space Shuttle Endeavor's fuel pump alone generated up 71,000 horsepower during lift off (about the equivalent power of 28 locomotives). It's oxygen pump generated around 23,000 hp and the three main engines... up to 37 million horsepower. en.wikipedia.org/wiki/RS-…
Sea Star Wasting Syndrome caused a huge die off in sea star populations along both US coasts (starting) in 2013. Initial studies suggested SSaDV to be responsible, but 2018-2020 studies indicated otherwise. Current theories include microrganisms living in sea star tissue and low oxygen levels en.wikipedia.org/wiki/Sea…
In 1986 a limnic eruption released 100,000–300,000 tons of CO2 from Lake Nyos. The amount of CO2 was so much that it displaced the oxygen in the surrounding area and suffocated 1,746 people and 3,500 livestock. en.wikipedia.org/wiki/Lak…
Today I learned about Goran Kropp. He rode a bicycle 6,000 miles from Stockholm to the base of Mount Everest in 1996 with his mountain equipment, successfully climbed it solo and without bottled oxygen, and then cycled back home. theguardian.com/world/200…
The claim that the amazon produces 20% of the world's oxygen and is false because of lack of Co2 in the air for photosynthesis. The actual estimate is close to zero due to other factors such as cellular respiration in trees and oxygen consumed by microbes for decomposition. nationalgeographic.com/en…

The cornea is the only part of the body with no blood supply and it gets its oxygen directly from the air shorelinevision.com/corne…
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…
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…
Dr. Khurshid Guru, the Director of Robotic Surgery at Roswell Park Cancer Institute in New York, saved the life of a child having an asthma attack aboard his transatlantic flight, by making a makeshift inhaler with a water bottle, cup, some tape, and an oxygen tank. bbc.co.uk/programmes/p039…
Flies don’t have lungs, and when submerged in a liquid don’t initially drown and instead go into β€œlow oxygen mode” (12:50 min in) abc.net.au/triplej/progra…
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…

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…
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
