...Obama Administration's "cap and trade" initiative, which is designed to curb both the use of energy and greenhouse-gas emissions across the entire economy. For carmakers, such legislation would be mostly neutral because they earn credit for making electric vehicles and could spend it on cars that emit too much CO2. GM now notes that one-third of the Cadillac Escalades it sell are hybrids, so it would have plenty of currency. Of course, at this point Detroit is hoping for anything that doesn't have California's fingerprints all over...
...written, using the Clean Air Act to regulate greenhouse-gas emissions directly would be unreasonably difficult, because of carbon dioxide's sheer ubiquity. In 2000, the U.S. emitted less than 18 million tons of the pollutant sulfur dioxide, chiefly from cars, power plants and factories. In the same year, national CO2 emissions reached nearly 6 billion tons, from virtually every aspect of modern life. Regulating emissions would be like trying to gather up the ocean. In addition, the Clean Air Act technically requires "major" sources of pollutants - meaning those that emit more than 250 tons a year - to acquire costly...
Using a pair of ions, or charged particles, group leader Christopher Monroe and his team place each in a vacuum and keep them in position with electric fields. An ultra-fast laser pulse triggers the atoms to emit photons simultaneously. If the photons interact in just the right way, their parent atoms enter a quantum state known as entanglement, in which atom B adopts the properties of atom A even though they're in separate chambers a meter apart. When A is measured, the information that had been previously encoded on it disappears in accordance with the quirky rules...
...personal trainer sometimes gives me an odd piece of advice during workouts: "Relax your face." For a long time, I found this advice confusing. Isn't physical exertion supposed to be expressed in grimaces? I thought of the face as a pressure-relief valve that helps emit the pain the body is experiencing. But the trainer suggested I think about it the other way around - that controlling the face can help control the mind...
Ants that are capable of reproducing naturally emit hydrocarbon-based odors, and the eggs they produce smell the same way. Ants that can't reproduce emit no such odor. Liebig and Smith produced a synthetic hydrocarbon in the lab that had the same olfactory properties as the natural one, then plucked a few innocent ants from a nest and dabbed the chemical on them. When they were returned to the colony, they were promptly attacked - never mind that they had essentially been framed...
