European scientists experienced the plant increase in space

During the European Columbus laboratory has begin the first research, which aim to examine whether plants might produce in outer space. The research, called WAICO ("Waving and coiling of Arabidopsis Roots at Different g-levels' or ripple and roll roots of Arabidopsis at different levels-g), study the effects of weightlessness on the growth of plant roots. Toward this purpose has selected a variety of wild and genetically modified plant Arabidopsis.

The United States could be causing the increase in the number of earthquakes

The dramatic increase in oil and gas in the United States could be causing the increase in the number of earthquakes in that country.According to the conclusion of an investigation by the U.S. Geological Survey, the number of earthquakes has increased six times. In just three years, increased the number of earthquakes from 50 in 2009 to 134 in 2011.

Experts say some tremors may be caused by the hydraulic fracturing method. This involves injecting a fluid mixture into the ground to cause the release of natural gas, or oil .
