Tue, 04 Jan 2011 00:00:00 -0800

UN demographers consider the middle road their best estimate: They now project that the population may reach nine billion before 2050--in 2045. The eventual tally will depend on the choices individual couples make when they engage in that most intimate of human acts, the one Leeuwenhoek interrupted so carelessly for the sake of science.

"Kite" Turbines Could Power Megacities Like New York and Tokyo, Research Suggests

Tue, 16 Jun 2009 00:00:00 -0700

National Geographic - By David Braun - Jun. 16 (News Report) - Five or six miles up in the atmosphere, near where airliners reach cruising altitude, very strong winds blow incessantly over many densely populated regions of the world. Researchers at the Carnegie Institution and California State University believe that, if the technical challenges can be resolved, large metropolises like New York, Seoul, and Tokyo may be able to tap into the high-altitude winds for abundant energy. One possible way to do this could be by using giant tethered kitelike wind turbines, like the one imagined in this illustration.

Amphibian Loss: The Vanishing

Thu, 19 Mar 2009 00:00:00 -0700

National Geographic - By Jennifer Holland - Mar. 19 (Special Report) - Amphibians are among the groups hardest hit by today's many strikes against wildlife. As many as half of all species are under threat. Hundreds are sliding toward extinction, and dozens are already lost. The declines are rapid and widespread, and their causes complex—even at the ravine near Limón the bulldozer is just one hazard of many. But there are glimmers of hope. Rescue efforts now under way will shelter some animals until the storm of extinction passes. And, at least in the lab, scientists have treated frogs for a fungal disease that is devastating populations around the world.

Canadian Oil Sands

Tue, 03 Mar 2009 00:00:00 -0800

National Geographic - By Robert Kunzig - Mar. 03 (Special Report) - Nowhere on Earth is more earth being moved these days than in the Athabasca Valley. To extract each barrel of oil from a surface mine, the industry must first cut down the forest, then remove an average of two tons of peat and dirt that lie above the oil sands layer, then two tons of the sand itself. It must heat several barrels of water to strip the bitumen from the sand and upgrade it, and afterward it discharges contaminated water into tailings ponds like the one near Mildred Lake. They now cover around 50 square miles. Last April some 500 migrating ducks mistook one of those ponds, at a newer Syncrude mine north of Fort McKay, for a hospitable stopover, landed on its oily surface, and died. The incident stirred international attention—Greenpeace broke into the Syncrude facility and hoisted a banner of a skull over the pipe discharging tailings, along with a sign that read "World's Dirtiest Oil: Stop the Tar Sands."
