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...

Ups And Downs Of Early Atmospheric Oxygen

Iqbal Pittalwala - University of California - Riverside UC Riverside research team challenges conventional view of a simple two-step rise in early oxygen on Earth; study suggests instead dynamic oxygen concentrations that rose and fell over billions of years A team of biogeochemists at the University of California, Riverside, give us a nontraditional way of thinking about the earliest accumulation of oxygen in the atmosphere, arguably the most important biological event in Earth...

Evolution Remained Stuck In Slime For A Billion Years
2014-02-19 15:18:39

Science in Public Tasmanian researchers have revealed ancient conditions that almost ended life on Earth, using a new technique they developed to hunt for mineral deposits. The first life developed in the ancient oceans around 3.6 billion years ago, but then nothing much happened. Life remained as little more than a layer of slime for a billion years. Suddenly, 550 million years ago, evolution burst back into action – and here we are today. So what was the hold-up during those 'boring...

[ Watch the Video: Theory On Origin Of Animals Challenged ] redOrbit Staff & Wire Reports - Your Universe Online In sharp contrast to the longstanding belief among scientists that advanced life on Earth was only able to evolve once atmospheric oxygen levels rose to near-modern levels, new research has discovered a small sea sponge which they claim proves that a high concentration is not needed in order for complex creatures to live and grow. According to the authors of the new...

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...
