Two billion years ago the Earth system was recovering from perhaps the single-most profound modification of its surface environments: the oxygenation of the atmosphere and oceans. This led to a series of major changes in global biogeochemical cycles, as a team around Aivo Lepland of the Norwegian Geological Survey NGU reports in the latest online edition of "Nature Geoscience". This also resulted in the distribution of one of life's key elements, phosphorous. Studies on the unique...

Brett Smith for redOrbit.com - Your Universe Online Elevated levels of oxygen in the atmosphere may have caused dinosaurs, insects and other organisms to grow to gigantic sizes millions of years ago, according to prevailing theories. If a new study from scientists at the Universities of Kansas and Alberta is correct, then the atmosphere of the Cretaceous had a relatively low oxygen content – making the high-oxygen theories severely flawed. “We do not want to negate the influence...

Spartan Environmental Technologies commissions its first oxygenation system for a bio filtration process to remove organic contaminants from groundwater. Because the groundwater is deficient in dissolved oxygen, a oxygenation system was required to increase the dissolved oxygen levels to support the biological digestion of organic contaminants. Beachwood, OH (PRWEB) November 06, 2013 Spartan Environmental Technologies commissions its first oxygenation system for a bio filtration process...

An Arkansas InventHelp client has invented the OX-IV, which is being submitted to companies for review. Pittsburgh, PA (PRWEB) November 05, 2013 Hospital patients are often hooked up to an array of medical devices, which really hinders their mobility. In order to make them more mobile, an inventor from Fort Smith, Ark., developed the OX- IV. The device offers a convenient way to secure an oxygen tank to an IV pole. The unit makes it easier for a C.O.P.D. patient who is hooked up to an IV...

Toxic Ocean Conditions During Ancient Extinction Event Analyzed
2013-10-30 04:24:55

redOrbit Staff & Wire Reports - Your Universe Online Toxic oxygen-free and hydrogen sulfide-rich ocean conditions that existed during a major extinction event nearly 94 million years ago could repeat themselves in the future, according to new research being published online this week in the journal Proceedings of the National Academy of Sciences. Research, led by biogeochemists at the University of California, Riverside, suggests that the previous estimates of these oxygen-free,...

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

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
