Earth's Oceans Oxygenated By First Sea Animals
2014-03-11 06:28:26

Lee Rannals for redOrbit.com - Your Universe Online Researchers at the University of Exeter say that the evolution of the first animals helped oxygenate the oceans. A long held belief says that oxygenation of the atmosphere and oceans were a pre-requisite for the evolution of complex life forms. However, the latest study published in the journal Nature Geoscience contradicts this belief. The latest study builds on previous research by scientists in Denmark who found that sponges...

Four New Ozone-Depleting Gases Discovered In Earth's Atmosphere
2014-03-10 10:15:19

Brett Smith for redOrbit.com - Your Universe Online New research from a European team of scientists has identified four new artificial gases in the atmosphere that are depleting the ozone layer, according to a report published Sunday in the journal Nature Geoscience. The report estimated that nearly 82,000 tons of three newly identified chlorofluorocarbons (CFCs) and one newly found hydrochlorofluorocarbon (HCFC) have been released into the atmosphere. “Our research has shown four...

The surface of the sea takes up nitrogen oxides that build up in polluted air at night, new measurements on the coast of southern California have shown. The ocean removes about 15 percent of these chemicals overnight along the coast, a team of atmospheric chemists reports in the early online edition of the Proceedings of the National Academy of Sciences the week of March 3. Nitrogen oxides, formed by the burning of fossil fuels, generate photochemical smog. Atmospheric chemists would like...

Organic Particle Ingredients Formed By New gas-phase Compounds
2014-02-27 11:53:49

Leibniz Institute for Tropospheric Research (TROPOS) Scientists made an important step in order to better understand the relationships between vegetation and climate. So-called extremely low-volatility organic compounds, which are produced by plants, could be detected for the first time during field and laboratory experiments in Finland and Germany. These organic species contribute to the formation of aerosol that can affect climate and air quality, they report in this week's issue of the...

when a pine-scented molecule combines with ozone in the surrounding air, some of the free radicals created in the process grab oxygen with unprecedented speed
2014-02-27 06:28:35

April Flowers for redOrbit.com - Your Universe Online For atmospheric scientists, pine forests are magical places where coniferous trees give off pine-scented vapors. These vapors form particles, rapidly and seemingly out of nowhere. A new study from an international group of scientists illuminates the process by which gas wafting from coniferous trees creates particles that can reflect sunlight or promote cloud formation. Both are important climate feedbacks. The findings, led by the...

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...

Geologic Clock With Events And Periods

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
