As the shuttle enters a new phase with this trip to the International Space Station (which soon will get outsourced shipping), check back next week for the Popular Mechanics take on the launch\u2014as usual. Top cosmologist Stephen Hawking urged today that humans need to colonize on other planets (though we might not be alone)\u2014or risk extinction from an asteroid or a nuclear war. New high-resolution and 3-D X-ray analysis of an ancient astronomical instrument reveal that it may have been complex enough to be considered the closest thing to the world&amp;#039;s first computer-like system after all, researchers report in the journal Nature today.  In a new twist to the global warming saga, the U.S. Supreme Court is preparing to tackle whether the Environmental Protection Agency can regulate motor vehicle emissions or carbon dioxide\u2014though future solutions, from alternative fuels to hydrogen to a high-tech diesel engine, abound. \u2013Matt Sullivan "^^<http://www.w3.org/2001/XMLSchema#string>
