British scientists have "artificial volcano"

British scientists have "artificial volcano" save the planet

It is known that volcanic eruptions, similar to what happened in the Philippines in 1991, have the ability to cool. In Britain since the end of 2011 an experiment to pump water at a distance of one kilometer from the ground into the air to test a new model of climate cooling, with which to launch into the stratosphere, sulfuric acid particles, capable of reflecting the sun.

A new experimental model of an artificial volcano is necessary for possible protection from damaging effects of climate change. The experiment is the first of

Can bacteria help break down harmful pollutants? It is interesting

For 50 years, scientists finally understand the mechanism of how bacteria can break down hazardous phosphorous acid decomposes slowly in the environment. It is estimated that each year more than 20,000 tons of phosphoric acid is released into the environment in the Western Hemisphere. Most of the discharged acid pollutes ground water, endangering human life, aquatic flora and fauna. This substance can be found in medical preparations, detergents and herbicides.

The study was conducted postgraduate chemical separation Canadian university Queens Mc Sorley Fernie and several assistants. The study identified the
