Matt had class that evening at Georgia State, an unskippable chem lab at 6:30, but that didn't keep him from chilling with us during its preliminary two-hour lecture. He, my brother and I were among the maybe 10 or 12,000 still hanging around, but after the rain that actually adds to the atmosphere: You know that everyone left loves the game, and besides, there's plenty of elbow room...
...most investigators agree that although the danger has not been proved, it is too plausible to ignore. The chain of reasoning goes something like this: animals exposed to high doses of these pollutants in the wild develop reproductive abnormalities. Animals exposed to low doses in the lab do too. Humans absorb comparable low doses simply by breathing, drinking and especially eating. Some of the suspect chemicals have physiological effects similar to those of estrogen and other sex hormones, or they at least interact with them; they might reasonably be expected to interfere with processes involving these hormones, such...
...conference gave rise to numerous collaborations, and participants began trading lab samples with one another and with a growing number of additional interested scientists. "We had gonads flying around the country," says Colborn. As the researchers compared notes, the evidence began to mount. During the mid-1980s, Colborn learned, mortality rates for alligator eggs in Lake Apopka, Florida, soared to 96%, in contrast to 57% in most Florida lakes. The almost certain cause: a 1980 chemical spill that included DDT. In 1993 researchers found that terns in PCB-contaminated Buzzard's Bay, Massachusetts, had reproductive-tract abnormalities including the presence...
...system is chemically different from everyone else's, so it's very difficult for a bacterium to develop a shield that offers universal protection. Diphtheria and tetanus can be prevented by vaccines if they are used properly. A vaccine against the pneumococcus bacterium has recently come out of the lab as well, and scientists expect to test one that targets streptococcus A within a year...
