In a lush pasture near Buenos Aires, this cow and its compatriots are digesting important information: how much methane—a greenhouse gas 20 times as potent as carbon dioxide—is released by the country's 55 million bovines. Researchers from Argentina's National Institute of Agricultural Technology connected inflatable tanks to the cows' first stomach, where methane is made, through a small hole between their ribs.
the Blu-ray format stores and plays movies in high definition—easy for new flicks shot digitally in HD, but what about classics like Metropolis (due out on Blu-ray next year) that were shot on film? The trick is to make a small digital file without losing too much information in the process, which could yield a poor-quality image. Here's how it works.
Ever since Russia planted a flag under the North Pole last year, the issue of sovereign rights under an increasingly slushy arctic has tensed. In a race to claim ownership of some of the arctic seabed, a two-ship caravan of Canadian and U.S. scientists is sailing around the Arctic Ocean right now. Their mission, which will last from September 6th to October 1st, is to measure the seabed and the continental margins in an attempt to solidify our possible rights over the far north—an area that will become accessible to oil drilling and mining as the earth warms and arctic ice melts.
This spring the New York City Department of Parks and Recreation released the draft environmental impact statement for the Fresh Kills Park Project, their plan to turn the Fresh Kills landfill—hitherto best known as a smelly Staten Island mountain—into a world class public park. The statement will be discussed at an open public hearing on September 4th, 2008, and work begins next year on the project's first small section—wrapping around the landfill's north mound and reaching down to the waterfront. This sliver should be finished within a few years, though the park in its entirety is expected to take around 30 years to complete, with $198 million in initial funding, but much more needed along the line.
