...hope that once the U.S. installs a friendly regime in Iraq--the Administration says it is still merely considering such a plan--Washington will end its alliance with the kingdom, its oil and bases no longer critical to U.S. interests. "If we sort out Iraq and Detroit develops a hydrogen engine," says a U.S. diplomat, "Saudi Arabia will go back to being a fascinating, benighted part of the world that people don't visit...
...hard to imagine a more inhospitable place on earth than the hydrothermal vents that pepper the ocean floor. These cracks in the sea bottom spew water superheated by rising magma to as high as 750[degrees]F and contaminated with toxic substances such as hydrogen sulfide, cadmium, arsenic and lead. Yet despite these lethal conditions, life not only survives but thrives in the form of colonies of microbes that feed on poison and multiply in temperatures that could hard-boil...
While their hardiness was a big surprise, the microbes' ability to eat hydrogen, sulfur, manganese and other chemicals--a process known as known as chemoautotrophy--was a revelation. Until then, all living systems were thought to depend on photosynthesis, using sunlight as a primary energy source. (Even cave-dwelling or deep-water creatures who never see the sun eat organic matter that ultimately originates from photosynthesis.) But if life could thrive without even indirect contact with sunlight, the amount of potentially habitable real estate on the planet would expand considerably...

...once warm and wet planet became cold and dry? After studying data from the orbiting Odyssey spacecraft, U.S. scientists believe it's still there, lying just below the surface as a huge sea of ice that future astronauts can tap for drinking water and as a source of hydrogen for fuel. Before human explorers head for Mars, much more study needs to be done by rovers and drill-equipped landers. Still, the scientists say, they're optimistic that the "ice signature" detected by Odyssey's instruments is just the tip of a Martian iceberg. EUROPEAN UNION Save Our Soles...
