Boulder Outdoor Survival School | BOSS New Desalination Technique Also Cleans and Disinfects Water One of the world’s most pressing needs is to supply clean drinking water to the its population. In rural areas, almost half the population does not have access to clean water so the challenge is clear and present. The problem, of course, is that most of the planet’s water is saline. So finding ways to desalinate seawater is a key goal. Martin Bazant, postdoc Daosheng Deng, and colleagues at the Massachusetts Institute of Technology in Cambridge, say they’ve developed a new way to desalinate water, known as shock electrodialysis, that not only removes salt but particulate matter and bacteria too. “Shock electrodialysis has the potential to enable more compact and efﬁcient water puriﬁcation systems,” they say. One of the big problems with desalination is its cost. The most common of these is reverse osmosis. So in recent years, engineers have begun to study a process called electrodialysis. But there is a problem with electrodialysis. Bacteria tend to be smaller though.

Cuba Announces Release of the World's First Lung Cancer Vaccine From the island nation known for the quality of its cigars comes some pretty big news today: Xinhua reports that Cuban medical authorities have released the first therapeutic vaccine for lung cancer. CimaVax-EGF is the result of a 25-year research project at Havana's Center for Molecular Immunology, and it could make a life or death difference for those facing late-stage lung cancers, researchers there say. CimaVax-EGF isn't a vaccine in the preventative sense--that is, it doesn't prevent lung cancer from taking hold in new patients. It's based on a protein related to uncontrolled cell proliferation--that is, it doesn't prevent cancer from existing in the first place but attacks the mechanism by which it does harm. As such it can turn aggressive later-stage lung cancer into a manageable chronic disease by creating antibodies that do battle with the proteins that cause uncontrolled cell proliferation, researchers say.

Trailspace: Outdoor Gear Reviews What is the universal edibility test?" Getting lost or stranded in the wilderness is serious business, and you need to make sound decisions to give yourself the best chance at survival. It also helps to know some basic wilderness survival skills. To make sure you're safe from the elements, you'll need to know how to build a shelter. But just because you can live without food doesn't mean you should. It's dangerous to eat a plant you're unsure of, especially in a survival scenario. If you're in a survival situation and you don't have a book on local edible plants, there is a test you can perform to give yourself a good shot at eating the right thing.
How Does Ozone Water Purification Work? What is Ozone in Relation to Water Purification?Ozone - or O3 - is Mother Nature's purifier and disinfectant. The 3 stands for the three oxygen atoms that compose Ozone. The normal Oxygen we breathe is called O2, and is made up of only two chemically linked Oxygen atoms. You may have noticed that a sudden summer storm leaves behind a very distinct smell, sort of a "fresh scent" which lasts for about an hour. How Does Ozone Kill Germs and Bacteria to Purify Water? How Do Ozonation Water Purifiers Make Ozone? The Ozone that has now been created inside the Ozone generator is then sent through a line into a diffuser, which creates ozone-saturated bubbles. This, of course, was the laymen's version of Ozone Water Purification.

Seeing Things? Hearing Things? Many of Us Do In other cultures, hallucinations have been regarded as gifts from the gods or the Muses, but in modern times they seem to carry an ominous significance in the public (and also the medical) mind, as portents of severe mental or neurological disorders. Having hallucinations is a fearful secret for many people — millions of people — never to be mentioned, hardly to be acknowledged to oneself, and yet far from uncommon. The vast majority are benign — and, indeed, in many circumstances, perfectly normal. Most of us have experienced them from time to time, during a or with the sensory monotony of a desert or empty road, or sometimes, seemingly, out of the blue. Many of us, as we lie in bed with closed eyes, awaiting sleep, have so-called hypnagogic hallucinations — geometric patterns, or faces, sometimes landscapes. At the other end of sleep are hypnopompic hallucinations, seen with open eyes, upon first waking. Misdiagnosis is especially common if people admit to “hearing voices.” Mr.
Kammok tarp collects rainwater for drinking Hammok manufacturer Kammok is working to bring an innovative new tarp to market. Not only does the tarp provide shelter from the rain, it funnels that rain into a gutter system and bottles it, providing a hassle-free way of procuring clean drinking water. View all Unlike other sources of water common in the wild, rainwater is inherently clean and a good option for refilling a water bottle, especially if you don't have a water purification system on hand. However, collecting water with narrow-mouthed bottles or hydration bladders can be difficult and ineffective. The Glider seeks to make rainwater collection easier with a dual-function design. The amount of water that the Glider system will collect obviously depends upon how much rain is falling. Another interesting feature of the Glider is that it's made from a new Cordura-based "Amphibiskin" fabric that includes both waterproofing and heat reflective coating.
