...addition to these poisons, the river harbors at least 28 varieties of viruses and an unknown number of bacterial strains, including typhoid, cholera, hepatitis and the three known types of polio virus. According to Gruenberg, bacteria levels routinely reach 1,000 times the maximum level set by the EPA as safe for bodily contact. Though no one uses the water for drinking or irrigation, infected drifts of foam from Mexican laundry detergents are sometimes scattered by the wind, and Cottrell fears an epidemic is inevitable. At greatest risk are illegal immigrants, who occasionally venture into the polluted suds to swim...

The next year the patient developed an AIDS-related form of pneumonia, and he died in 1984. His wife tested positive for the AIDS antibodies, and was later diagnosed as having...
...last week southern hemisphere observatories reported that the supernova's magnitude, which had remained relatively constant for almost two weeks, showed signs of increasing slightly, from 4.5 to 4.25. But even if 1987A stays "subluminous," it will be important because it may point to the existence of a previously unknown class of stellar explosion...
