Oxygen-16, one of the key elements of life on earth, is produced by a series of reactions inside of red giant stars. Now a team of physicists has revealed how the element’s nuclear shape changes depending on its state, even though other attributes such as spin and parity don’t appear to differ.

Earth's Oceans Oxygenated By First Sea Animals

Oxygen Therapy
2013-04-30 10:27:06

Oxygen therapy is known as the administration of oxygen as a medical intervention. It is indicated in patients whose oxygen supply is compromised due to both acute and chronic health conditions and can be administered in many different ways. Oxygen therapy can be administered virtually wherever the patient is. Most commonly, oxygen is delivered to patients in an ambulance, hospital, or doctor’s office. These medical facilities carry oxygen in the form of a compressed gas. It is stored...

The Paleoproterozoic is the first of three subdivisions of the Proterozoic Eon (occurring from 2.5 billion to 1.6 billion years ago (Ga). This period is marked by the first stabilization of the continents, and also when cyanobacteria--a type of bacteria that uses biochemical processes of photosynthesis to produce oxygen--evolved. Experts have found paleontological evidence that during at least part of the Paleoproterozoic era, about 1.8 Ga, the earth year was about 450 days long, with days...

Earth's Atmosphere
2004-10-19 04:45:44

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...
