...proposed rule marks the first time the Federal Government has tried to regulate stationary sources of greenhouse-gas emissions. But again, the details are far from certain. It's not clear yet what "best available technology" will mean for carbon - especially in the case of new coal plants, which have no real way to drastically limit carbon emissions. And the rule is certain to come under attack from industry opponents; by putting only large emitters under the proposed rule, the EPA saves a lot of expense for small businesses but could be accused of being unfair to larger ones...
...knuckle-walking, tree-swinging ape. But "[Ardi is] not chimplike," according to White, which means that the last common ancestor probably wasn't either. "This skeleton flips our understanding of human evolution," says Kent State University anthropologist C. Owen Lovejoy, a member of the Middle Awash team. "It's clear that humans are not merely a slight modification of chimps, despite their genomic similarity." (See "Darwin and Lincoln: Birthdays and Evolution...
Scientists know this because they've studied not only Ardi's fossils but also 110 other remnants they uncovered, which belonged to at least 35 Ar. ramidus individuals. Combine those bones with the thousands of plant and animal fossils from the site and they get a remarkably clear picture of the habitat Ardi roamed some 200,000 generations ago. It was a grassy woodland with patches of denser forest and freshwater springs. Colobus monkeys chattered in the trees, while baboons, elephants, spiral-horned antelopes and hyenas roamed the terrain. Shrews, hares, porcupines and small carnivores scuttled in the underbrush. There...
...will hold - and there is even a real possibility that the repair work could just ensure that the gravel collapses in one chunk, as opposed to failing in pockets - should the anticipated rains arrive, the only relatively safe option will be to deliberately release the dam. "What is crystal clear is that there will be a devastating impact if the water is released," Triplett says. The Federal Emergency Management Agency (FEMA) estimates that if the dam needs to be released, the resulting damage could cost $3 billion. County officials estimate that the ensuing shutdown of business could cost the area...
...countries that it give up the right to enrich uranium, even for peaceful purposes, because of concerns about its intentions. Washington and its allies are debating whether the West can sustain that demand or could accept continued enrichment in Iran but under stricter safeguards against weaponization. Iran is making clear where it plans to start the discussion. As Iran's Foreign Minister, Manoucher Mottaki, told the New York Times on Sept. 29, Iran sees the talks as a "two-way street" rather than simply a last chance to respond to a series of Western ultimatums.
