...sheer ubiquity of carbon is what makes eliminating greenhouse-gas emissions so difficult. But the surprising truth, Roston writes, is that we have actually been decarbonizing over time. Humanity's main fuel for eons was wood, which has a carbon-to-hydrogen ratio of 10 to 1 when burned; by comparison, that ratio is 2 to 1 for coal and 1 to 2 for oil. The problem is that we're burning ever larger amounts of fossil fuels, putting a greater concentration of carbon into the atmosphere than has been seen for millions of years. Though carbon has its positive...
...helping the millions left homeless. But demonstrations during the Games could reignite it, says Victor Cha, director of Asian Studies at Georgetown University and author of the forthcoming book Beyond the Final Score: The Politics of Sport in Asia. "Protests by foreigners would infuriate the Chinese and only fuel their reactive nationalist view that the West is trying to ruin China's moment in the sun," he says...
...most recent venue, the distinctly nonrural borough of Manhattan, is not as incongruous as it seems. With its estimated 600 small-scale farms (which are often large-scale vegetable gardens), New York City is part of an urban agricultural boom in the U.S., where rising food and fuel prices are making city farming seem less and less outlandish. In July volunteers began transforming the front lawns of San Francisco's city hall into the first edible offerings on that site since 1943, when civilians across the country were encouraged to aid the war effort by growing victory gardens...
Those questions fuel the debate over whether the information amounts to medical advice. Many doctors say it does. Most companies, including 23andMe, disagree; they say they are simply offering customers genetic information that already belongs to them. If so, how useful is that information? Again, many doctors say it's still far too early to gauge its benefit, because consumers are not capable of interpreting their genetic information or making any meaningful changes in lifestyle or health based on it. In January, Dr. Jeffrey Drazen, editor of the New England Journal of Medicine, co-authored a commentary questioning the tests...
...boron on the exposed reactor core in order to stop the massive leakage of radiation. For the long term, Moscow's plan is to enclose the unit in a concrete tomb equipped with a cooling system to dissipate heat generated by more than 150 tons of active nuclear fuel still in the reactor. In the city of Kiev, 80 miles to the south, Soviet authorities are taking precautions against the spread of radiation into the water supply. Emergency wells are reportedly being dug to be used in the event that reservoirs fed by rivers become contaminated. Officials insist that radiation...
