At this year's Shell Eco-marathon Americas event the team from Mater Dei High School shattered last year's record by traveling 2,843.4 miles on a single gallon of gasoline. "How did the Evansville, Ind., team come up with its winning airfoil-meets-teardrop design and beat out its largely collegiate competitors? "It comes from trial and error, seeing what works and what doesn't," an unidentified student and team member told a local newscaster Friday. Those top three vehicles, like most in the competition (25 out of 33 total), used internal combustion engines. The goal for all entrants was to travel as far as possible using as little fuel as possible. Vehicles--sans driver--couldn't weigh more than 160 kilograms (352 pounds), while drivers had to weigh at least 50 kilograms."

They're the ones who installed their own Wi-Fi network in the break room and distribute homemade number-crunching apps to their coworkers on e-mail. They're hacking their iPhones right now to work with your company's mail servers. In short, they're walking, talking IT governance nightmares. But they could be your biggest assets, if you use them wisely. The reason superusers go rogue is usually frustration, says Marquis. "It's a symptom of the IT organization being unable to meet or even understand the needs of its customers," he says. "Otherwise, it wouldn't be happening." The solution? Put them to work.'"

The company used satellite images to study the movements of the two ships, and shared the information with officials in Dubai, who impounded the two vessels. The NANOG list has a discussion of where Reliance might have obtained satellite images to provide that level of detail. Google News links more coverage of the developments."

Ant writes in to note a study indicating that, because of air pollution, the smell of flowers is not wafting as far as it once did. Pollutants from power plants and automobiles destroy flowers' aromas, the study suggests: "The scent molecules produced by flowers in a less polluted environment, such as in the 1800s, could travel for roughly 1,000 to 1,200 meters; but in today's polluted environment downwind of major cities, they may travel only 200 to 300 meters." The finding could help explain why some pollinators, particularly bees, are declining in certain parts of the world.

theodp writes "PC World reports that DHS has extended the time foreign graduates of US colleges can stay in the country and work to almost two-and-a-half years, an 'emergency' change that drew kudos from Microsoft and other H-1B visa stakeholders. Looks like when Bill Gates says 'Jump,' the government asks 'How high?' Bill Gates's Congressional Testimony, March 12, 2008: 'Extending OPT from 12 to 29 months would help to alleviate the crisis employers are facing due to the current H-1B visa shortage. This only requires action by the Executive Branch, and Congress and this Committee should strongly urge the Department of Homeland Security to take such action immediately.' DHS Press Release, April 4, 2008: 'The US Department of Homeland Security released today an interim final rule extending the period of Optional Practical Training (OPT) from 12 to 29 months for qualified F-1 non-immigrant students.'"
