Earthen Crust Oxygen Got Its Start During Creation Of Solar System
2013-10-25 07:03:56

April Flowers for redOrbit.com - Your Universe Online A long standing mystery in the formation of the Solar System has been solved by cosmochemists from the University of California, San Diego (UCSD). In the oldest, most pristine rocks, oxygen, the most abundant element in the Earth's crust, follows a strange, anomalous pattern that must result from a different chemical process than the well-understood reactions that form minerals containing oxygen on Earth. "Whatever the source of...

Oxygen Levels Prior To The Cambrian Explosion May Have Been Enough For Life
2013-10-19 05:00:29

redOrbit Staff & Wire Reports - Your Universe Online An international team of researchers has discovered that the Earth’s oxygen content 2.1 billion years ago was the same as it was during the so-called Cambrian explosion that occurred approximately 542 years ago and resulted in the appearance of most major animal phyla. Given the fact that oxygen and the development of advanced life are inextricably linked, this led the study authors to ponder the sudden emergence of living...

The peroxisome, a tiny intracellular organelle, was discovered in the mid-1960s, and for nearly 50 years scientists were unsure of how it and TSC2 worked. Now a team at Texas A&M Health Science Center (TAMHSC) Institute of Biosciences and Technology (IBT) know that TSC2 keeps peroxisomes at the right levels to maintain healthy cells. Houston, TX (PRWEB) October 10, 2013 When it comes to survival on the cellular level, mysteries have abounded for decades. In a paper published in the...

In a study published in published in EMBO Molecular Medicine, a Dartmouth researcher found that dying heart cells are kept alive with spikes of oxygen. During a heart attack when the flow of oxygen-rich blood to a section of the heart is interrupted, and not quickly restored, heart muscle begins dying. Deprived of oxygen and other essential nutrients, cell death continues occurring over a period of time leading to progressive loss of heart function and congestive heart failure. Current...

If we're to meet a goal set by the U.S. Environmental Protection Agency's Renewable Fuels Standard to use 36 billion gallons per year of biofuels—mostly ethanol—the nation must expand its infrastructure for transporting and storing ethanol. Currently, ethanol is transported via trucks, trains, and barges. For the large volumes required in the future, transportation by pipeline is considered to be the most efficient method to get it to customers. The integrity and safety of pipelines...

Scientists Document Scavenging For Oxygen In Seawater Circulating Through Deep Oceanic Crust
2013-09-27 11:16:26

Bigelow Laboratory for Ocean Sciences Although long thought to be devoid of life, the bottom of the deep ocean is now known to harbor entire ecosystems teeming with microbes. Scientists have recently documented that oxygen is disappearing from seawater circulating through deep oceanic crust, a significant first step in understanding the way life in the "deep biosphere" beneath the sea floor is able to survive and thrive. The new research findings were published in the journal Nature...

Life-Bearing Oxygen Appeared On Earth Three Billion Years Ago
2013-09-26 07:19:54

April Flowers for redOrbit.com - Your Universe Online New research from the University of Copenhagen and University of British Columbia (UBC) has revealed that oxygen appeared 700 million years earlier than we previously thought. The findings, published in the journal Nature, raises new questions about the evolution of early life. The research team examined the chemical composition of three-billion-year-old soils from South Africa, which are the oldest soils on Earth. They found...

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...
