But while the U.S. and other Western nations have made great strides in containing the virus at home, over the past two decades AIDS has grown into a pandemic across the developing world. The disease has spread to such a degree that, according to U.S. and U.N. security experts, AIDS now poses a major threat to global stability. According to a report in Sunday's Washington Post, the Clinton administration has recently made combating AIDS in developing countries a top federal priority, and, for the first time...

Not only would there be many fewer life forms, but also faunas and floras would look much the same over large parts of the world, with disaster species such as fire ants and house mice widely spread. Humanity would then have to wait millions of years for natural evolution to replace what was lost in a single century...
...city has good rail and bus lines, then development can be concentrated around mass-transit stops rather than spread out all over the countryside.

Some of the most promising natural wonder drugs come from compounds not usually associated with healing: poisons. Merck is marketing a blood thinner based on the venom of the deadly saw-scaled viper. A protein from another Asian pit viper is being studied because it appears to inhibit the spread of melanoma cells, and a compound called SNX-482 from the venom of the Cameroon red tarantula may lead to new treatments for neurological disorders...
