...ease the environmental impact of coal power by using clean-burning technology and by encouraging energy conservation. EVN has launched a rebate campaign promoting power-saving fluorescent lightbulbs; Vietnam recently passed a clean-air law that requires new coal plants to install filters for toxic sulfur dioxide and nitrogen. In Uong Bi, EVN installed filters on the new generator's smokestack - a measure that tea-shop owner Dang says has reduced the black smoke. But even the most advanced technologies can't cut CO2 emissions by much. Carbon sequestration - a proposed method of fighting global warming that siphons off carbon...
...have seen firsthand how Mbola's farming households suffer from a recurrent drought--not of water but of nitrogen and other nutrients needed to achieve a decent harvest. Previous harvests have exhausted the soil because Mbola's farmers could not afford chemical or organic fertilizers...
Still on the cutting edge of chemistry research, Schrock reduced nitrogen gas to ammonia in his lab four years ago, the first time such a reaction has been carried out artificially...
...several thousand dollars (Krtolica declined to provide an exact figure, citing ongoing talks with a few IVF clinics). There scientists thaw and nurture the embryos to generate stem cells. These are then removed, cultured and allowed to grow. The surviving colonies are then frozen and kept cryopreserved in liquid nitrogen in StemLifeLine's own freezers on the premises. (The company charges about $350 per year to keep the cells in deep freeze...
...removing about 800,000 of Beijing’s nearly three million vehicles from the road during the conference—and pushing people to make greater use of busses and subways—officials cut the city’s concentration of a certain type of harmful nitrogen oxide by 40 percent. Yuxuan Wang, one of the post-doctoral fellows who worked on the study, said that the results were promising. “We do see large reduction in emissions, so that demonstrates traffic restrictions were very effective,” she said. The November 2006 program...
