Should the periodic table bear a warning label in the 21st century or be revised with a lesson about elemental supply and demand? If so, that lesson could start with one element considered a staple of life — but growing endangered, like the Asiatic dhole — phosphorus. Why is phosphorus pivotal? Phosphorus is in the DNA of all plants and animals. It is a key ingredient in fertilizer, but high quality phosphate deposits for mining are limited in both quantity and locality....

Scientists Detect First-Ever Arctic Ozone Hole
2011-10-03 05:19:46

A team of international researchers, led by NASA scientists, has discovered an unprecedented loss of protective ozone in the atmosphere above the Arctic this year, according to various media reports published on Sunday. That phenomenon, according to an AFP article, has led to the formation of an ozone hole five times the size of the state of California. It marks the first time that ozone loss in the Arctic region has matched ozone loss above Antarctica, both they and Postmedia News are...

North America Safe From Impact Of Satellite
2011-09-23 09:32:11

  NASA said on Friday that its Upper Atmosphere Research Satellite (UARS) will most likely miss North America. Scientists have still not pinpointed exactly where the 13,000-pound satellite is going to end up. The space agency said the odds of a piece of debris striking a person are about 1-in-3,200.  Scientists predict 26 pieces of debris will survive Earth's atmosphere, weighing a total of 1,100 pounds. UARS will re-enter Earth's atmosphere sometime Friday afternoon,...

   ESA´s Envisat observation satellite yesterday completed its 50,000th circuit of Earth — travelling 2.25 billion km since its launch nearly a decade ago. Envisat orbits our planet every 100 minutes, speeding along at more than seven kilometers per second. During this milestone spin around the world on 22 September, the satellite passed from the Arctic to the Antarctic, catching glimpses of northern Greenland and New Zealand. Launched on 28 February 2002, the...

Pollution Increases Heart Attack Risk
2011-09-21 11:19:03

   According to a study published in the British Medical Journal, high levels of pollution could increase the risk of having a heart attack for up to six hours after exposure. U.K. researchers reviewed 79,288 heart attack cases from 2003 to 2006 and exposure to pollution levels by the hour. Krishnan Bhaskaran, an epidemiologist from the London School of Hygiene and Tropical Medicine, and colleagues used the U.K. National Air Quality Archive to investigate the levels of...

Satellite Crashing Into Earth In T-Minus ???
2011-09-21 11:07:02

  NASA said there is a 1-in-3,200 risk that a person who is minding their own business might find themselves being chased down by a defunct satellite the size of a tour bus traveling at 17,500-miles-per-hour. Of course, the odds of that exact scenario are higher, but the space agency did warn of the potential risk of being hit by falling debris from its Upper Atmosphere Research Satellite (UARS). According to estimates, the satellite will arrive back into Earth's atmosphere...

Obama Asks EPA To Withdraw Clean Air Regulations
2011-09-04 05:17:22

  In what the Associated Press is calling a "dramatic reversal," President Obama requested that the Environmental Protection Agency (EPA) shelve new air-quality regulations, citing concerns that they could stifle job growth in the energy industry. "The surprise move--coming on the same day as a dismal unemployment report--reflected the energy industry's importance as a rare bright spot in adding U.S. jobs. The tighter standards for smog-forming ozone could have forced states and...

Atlantis launched from Kennedy Space Center on November 3, 1994 at 11:59 AM EST and landed at Edwards AFB on November 14 at 7:33 AM PST. The shuttle orbited 174 times at an altitude of 164 nautical miles at an inclination of 57 degrees and travelled 4.5 million miles. The mission lasted 10 days, 22 hours, 34 minutes, and 2 seconds. This mission further advanced efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere, and how these factors affect...

Today's soil contamination is a direct result of man-made chemicals or other changes in nature's soil environment. This contamination most commonly occurs from underground storage tanks bursting, use of pesticides, discarding oil and fuel illegally, leakage of dirty surface water, draining of wastes from landfalls and knowingly dumping industrial wastes into the soil. The most widespread chemicals found are petroleum hydrocarbons, solvents, common pesticides, lead and additional heavy metals....

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...
