...radiation"). This bug can live in a blast of gamma rays that is the equivalent of thousands of lethal human doses--radiation so strong it cracks glass. Scientists have found "dead" radiodurans spores in Antarctica that have baked in UV light for 100 years. Yet when placed in a nutrient bath, the bug's DNA reassembles itself and proliferates. If radiodurans genes could be put into anthrax, they might produce an anthrax that's virtually impossible to kill. From a bioweaponeer's point of view, the future is bright...
...find an expert somewhere to support almost every one. Though Atkins' high-fat regimen has drawn widespread criticism in the medical community, it has vocal adherents as well. Dennis Gage, an endocrinologist at Lenox Hill Hospital in New York City, immediately takes his patients off relatively nutrient-poor pastas and white breads. Like many of the diet gurus, he argues that naysayers are using outdated science. "Some of the registered dietitians trained the old-fashioned way, saying you have to have 50% carbohydrates. The government is always behind. The next update will probably correct that." And it's hard...
...noticed. But humans are also affected when they eat fish contaminated by PCBs; the chemicals can cause cancer and disrupt the functioning of hormones in the body. Other forms of pollution, like nitrate and phosphate runoff from farms, kill the ecosystem by starving fish. These nutrient pollutants are found in fertilizer and in sewage, and they cause excessive growth of aquatic plants when they hit the water. Algae, during their natural course of life, die and sink to the bottom, where they are devoured by bacteria, which use oxygen. Too many algae deprive fish of oxygen...
...danger in giving kids their Flintstone vitamins. Her concern is that too many people are taking huge doses without much evidence that they will do any good and without considering the harm they might cause. "If you have reason to believe that you are shortchanged on a single nutrient, you have to know what the risks are," she says. "That may require a consultation with a professional nutritionist, not a conversation with your neighbor, a chiropractor or a health-food-store employee." Now if only common sense came in a pill...
...singled out. "I don't think it's been proved yet," says Ralph Smith, whose family operates seven chicken houses on the Eastern Shore. "They're pointing fingers our way, but it's probably a combination of things." The poultry industry has already reacted angrily to calls for mandatory nutrient-management legislation, and followers of state politics predict it will use its clout in the legislature to fight any new restrictions. "Poultry farmers are a small voting bloc, and many don't make a lot of money, but the poultry industry is very wealthy and has been very active...
