...species on the planet at risk for extinction. A warming trend of 3 degrees would puts millions of human beings at risk from flooding, wetlands would be lost and there would be a massive die-off of sea corals. Sea levels would rise by 28 to 43 cm, and most frightening of all, the report acknowledged the possibility that the melting of the Greenland ice sheet, which would release enough fresh water to swamp coastal cities, could occur over centuries, rather than millennia. "If you add to this the melting of some of the ice bodies on Earth, this gives...
This telltale flicker is easy to spot even from a small, ground-based telescope. So Charbonneau is setting up an array of eight 16-in. (40 cm) telescopes on Mount Hopkins, near Tucson, Ariz., and pointing them over and over at the 100 closest M-dwarfs to see if their light dims in a repeating pattern. If it does, he won't have long to wait: a habitable M-dwarf planet would have a "year" only three or four days long, so transits would happen all the time. Things will get even easier in 2009, when NASA launches a satellite...
...planted roof usually comes in one of two varieties: extensive or intensive. The extensive type is wide and shallow, with a soil depth of less than 8 in. (20 cm), able to support smaller plants. The intensive type may be smaller, but it's deeper and home to larger plants. Whatever the design, green roofs are a lot more complicated than ordinary gardens. They have multiple layers beneath the soil, including a filter membrane, a drainage layer, waterproofing, insulation and structural support...
...costs rather than ride a pony or eat corn dogs. John Deere salesmen showed off their largest machinery ever, including a 530-horsepower tractor and a combine that costs $410,000 fully equipped. At the Firestone tent, a rep said the company is preparing a 91-in. (230 cm) farm tire, taller than Yao Ming. TopCon Precision Agriculture exhibited GPS gadgets that adjust your spraying and watering according to the topography of your fields and can even steer your tractor. ADM Financial advisers showed how to hedge risk in futures markets, while a lecturer at Monsanto's Biofuture tent touted...
...differences don't stop there. Studies in the Philippines show that later-born siblings tend to be shorter and weigh less than earlier-borns. (Think the slight advantage the 6-ft. 5-in. [196 cm] Peyton Manning has over the 6-ft. 4-in. [193 cm] Eli doesn't help when he's trying to throw over the outstretched arms of a leaping lineman?) Younger siblings are less likely to be vaccinated than older ones, with last-borns getting immunized sometimes at only half the rate of firstborns. Eldest siblings are also disproportionately represented in high-paying professions. Younger siblings...
