Huge Reservoir Discovered Beneath Asia 273

anthemaniac writes "Seismic observations reveal a huge reservoir of water in Earth's mantle beneath Asia. It's actually rock saturated with water, but it's an ocean's worth of water ... as much as is in the whole Arctic Ocean. How did it get there? A slab of water-laden crust sank, and the water evaporated out when it was heated, and then it was trapped, the thinking goes. The discovery fits neatly with the region's heavy seismic activity and fits neatly with the idea that the planet's moving crustal plates are lubricated with water."

The Senator said he wanted to free America from what he called "the tyranny of oil," and went on to promote alternative energy sources such as ethanol (a big political winner in the midwest where he announced, because of all the corn farmers). He also talked about using science and technology to help those with chronic diseases, which is likely to have been an allusion to his staunch support of stem cell research. Perhaps most of interest to Slashdotters however is that Obama made the following statement halfway through his speech: "Let's invest in scientific research, and let's lay down broadband lines through the heart of inner cities and rural towns all across America. We can do that." Like nearly everything in his speech, this was met with robust applause from the crowd. You can watch a video of the entire speech at Obama's website."
