The  Ultraviolet (UV) light disinfection system is widely used throughout the world to produce clean water.  However, it has problems that are seldom mentioned. Microorganisms are removed but salts, petroleum products, pharmaceuticals, heavy metals and chlorine are not.  The method does use huge amounts of electricity, so there is always the danger of outage.  If the base water has solids this blocks light and it does not work. purify New in Way on Water Discovered purify Scientists have been trying to find another way for a long time.  The Australian National University has managed to identify and alternative. Organic pollutants are decomposed by using modified titanium dioxide as a photocatalyst on sunlight.  Nitrogen and niobium atoms boost the process.  Discovered water purify ways new.

The NSA has said that it targeted non-US citizens in its information grab from large Internet companies. Australian and American government agencies have secured detailed data about Australian citizens. This fact came out in a new report. In the first half of 2013 546 requests were made on Australians. Facebook provided details on 349 of these. The US demanded information on 20,000 users assumed to be Americans. Access was granted on nearly 16,000 US accounts. Which government agencies made the demands was not announced by Facebook. Internet companies seem to have been given some sort of filtering power to decide what is released. This is strange considering such companies are not elected non-government agencies. Are they entitled to be above the law? Requests to Twitter by Australia have risen 600 percent since the second half of 2012. All members of the international data oligopoly were approached.

Eons ago ancestors of whales made a major leap forward in evolution of their mouths. Whales living today can filter-feed in large amounts because the lower jaw is flexible in movement. Ancient fossils such as Janjucetus hunderi do not have such a mobile lower jaw. The development of this attribute probably initially evolved to consume large living prey. It began with a wide upper jaw and normal teeth - no comb filters. Erich Fitzgerald from the Museum Victoria in Melbourne has created a family tree showing whale evolution. The way whales feed is unique. It is believed that sucking when feeding still takes place, a left over from the days of the wide upper jaw. A big question is why whales went back into the sea in the first place. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://adventure--australia.blogspot.com . . . . . . . . . ...
