Photosynthesis Measurements From Space
2014-03-25 10:22:18

Carnegie Institution Plants convert energy from sunlight into chemical energy during a process called photosynthesis. This energy is passed on to humans and animals that eat the plants, and thus photosynthesis is the primary source of energy for all life on Earth. But the photosynthetic activity of various regions is changing due to human interaction with the environment, including climate change, which makes large-scale studies of photosynthetic activity of interest. New research from a...

Oxygen’s Different Shapes Described By Researchers
2014-03-14 14:31:07

North Carolina State University 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, including one from North Carolina State University, 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. Their findings may shed light on how oxygen is produced. Carbon and oxygen are formed when helium burns...

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...

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...
