Billions of years ago cyanobacteria gained photosynthesis to generate their own food from the sun. This released a lot of oxygen in the atmosphere, which should have poisoned the bacteria. Somehow, they gained the ability to resist oxygen damage.

The "Catch-22" problem is how did they evolve the ability before there was a need? Scientist feel they may have discovered the reason. picked by 2manyusernames 3 years ago

Some seals and dolphins can hold their breath underwater for a cheek-popping hour or more without passing out from lack of oxygen. The secret to the superhero animal feat is elevated levels of special oxygen-carrying proteins found in their brains, a new study reveals. But the research leaves puzzles. picked by AutumnLotus 2 years ago

Jupiter's moon, Europa has ocean water twice as much as all of the Earth. New evidence indicates that not only is there enough oxygen to support microorganisms but perhaps even enough to support greater lifeforms. The time it will take to unlock this oxygen is a good sign for eventual life as it gives time for organisms to evolve protection against oxygen's harmful effects. picked by bernardblack 1 month ago

This Chandra X-ray Observatory image shows the debris of a massive star explosion in the Large Magellanic Cloud, a small galaxy about 160,000 light years from Earth. The supernova remnant (SNR) shown here, N132D, is the brightest in the Magellanic clouds, and belongs to a rare class of oxygen-rich remnants. Most of the oxygen that we breathe on Earth is thought to have come from explosions similar... read full post picked by AutumnLotus 2 years ago

"The umpire said I couldn't play because of my tank, because of my oxygen,” Garcia told KGW.

A startling discovery by scientists at the Carnegie Institution puts a new twist on photosynthesis, arguably the most important biological process on Earth. But two studies suggest that certain marine microorganisms have evolved a way to break the rules--they get a significant proportion of their energy without a net release of oxygen or uptake of carbon dioxide. picked by AutumnLotus 2 years ago

Desir said she was having trouble breathing and asked for oxygen, but a flight attendant twice refused her request, Oliver said Sunday in a telephone interview. picked by dollyllama 2 years ago

According to Biochemist Graham Logan it did. In brief, containing digestion bi-products in parcels of poop meant that there was less for the bacteria to chew on. This led to less bacteria, and it was the bacteria who were burning up all the oxygen. Which meant there was more oxygen around to play with and the Cambrian Explosion ensued picked by pocksucket 2 years ago

Scientists at the University of Bonn have discovered a new rare type of haemoglobin. The new haemoglobin type appears optically to be transporting little oxygen. Measurements of the blood oxygen level therefore present a similar picture to patients suffering from an inherited cardiac defect. After examining two patients, the scientists now understand that the new type of haemoglobin distorts the l... read full post picked by AutumnLotus 2 years ago

A mineral that acts like a sponge beneath Earth's surface stores more oxygen than expected, keeping our planet from becoming dry and inhospitable like Mars. The key to the abundant oxygen storage is the mineral majorite, which exists deep below Earth's surface in the mantle. Without the oxygen stockpile, Earth would probably be a barren planet hostile to life. picked by AutumnLotus 2 years ago

Oxygen is constantly leaking out of Earth’s atmosphere and into space. Now, ESA’s formation-flying quartet of satellites, Cluster, has discovered the physical mechanism that is driving the escape. It turns out that the Earth’s own magnetic field is accelerating the oxygen away. picked by AutumnLotus 1 year ago

As reservoirs of valuable information go, nothing beats the sun. This sphere of heat and energy holds 99.9 percent of the solar system, saved in all original proportions after planets and meteorites formed. Analyzing the mix of hydrogen, oxygen and noble gases found in the sun can answer one of the biggest questions of the universe: How did our solar system evolve? picked by AutumnLotus 2 years ago

The first lungless frog has been discovered lurking in the jungles of Borneo. It apparently gets all the oxygen it needs through its skin. The loss of lungs helped the frogs severely flatten their bodies. This in turn increased the surface area of their skin, which helps them absorb oxygen. picked by 2manyusernames 2 years ago
