...paper, Stavins and Hahn used current-day examples—such as the sulfur dioxide trade amendment in Ohio that aimed to substantially reduce acid rain—to prove that the cap-and-trade system would work both in theory and in practice...
...acid test of a movie's popularity is its staying power. Tyler Perry's Why Did I Get Married Too? fell a precipitous 62.4% from its opening three days - the biggest second-weekend drop since Valentine's fell 70.4%. Perry's fan base is avid but limited; nearly everyone who wants to see his films sees them the instant they hit the theaters. Other movies keep soaring on good word of mouth. How to Train Your Dragon opened two weeks ago at $43.7 million, on the weak side for a DreamWorks 3-D animated feature. But it fell only...
...Even if leaders on both sides want good ties, they may succumb to the acid test of any foreign policy: domestic support.

...discharge cycles over an eight-to-10-year life cycle. The battery has to absorb energy from braking and provide short bursts of power for acceleration. Lithium-ion batteries, with their high density-to-weight ratio, provide the greatest acceleration and range with the fewest batteries compared with lead-acid or nickel-metal-hydride batteries. One big problem: they can overheat and even blow up - bad enough in a single-battery laptop but potentially disastrous in a multibattery electric car. So engineers have been busy resolving the heat problem and refining the batteries' ability to handle partial charge-discharge cycles...
...administered chloroform and claimed he observed the animal trying to sting itself. To prove him wrong, the psychologist Conwy Lloyd Morgan set up a series of traps for the critters. "He surrounded them with fire, condensed sunbeams on their backs, heated them in a bottle, burned them with phosphoric acid, treated them with electric shocks and subjected them to 'general and exasperating courses of worry,' " notes the Endeavour article...
