...concept of cloning, not the reality, to which the media and the public reacted. It conjured up visions of baby factories, mass-produced humanity, a world populated by carbon-copy people. The reaction was overwhelmingly negative: A Time survey showed that 75% of those polled believed that human cloning is not a good thing, and 77% want cloning research to be temporarily halted or banned altogether...
Another option is to buy one of the many filters or other water-purifying devices on the market. Be sure to choose one that specifically removes the toxins turning up in your water. Carbon filters, for example, are good at purging organic compounds, such as pesticides and solvents, but they will not remove minerals or most heavy metals. And one of the more elaborate devices, a distiller, is excellent at taking away heavy metals but is not effective against chloroform and benzene...
...crystal ball and glimpse at the future of cloning? One way might be to look at the livestock industry, the proving ground for reproductive technology. More than a decade has passed since the first calves, lambs and piglets were cloned, and yet there are no dairy herds composed of carbon-copy cows, no pigpens filled with identical sows. While copying particular strains of valuable plants such as corn and canola has become an indispensable tool of modern agriculture, cloning farm animals, feasible as it may be, has never become widespread. Even simple embryo splitting, the technique used by the George...
After an experiment in which two U.S. researchers made carbon copies of human embryos, the whole world debated whether science had finally stepped over the line...
Ever since the threat of global warming seared its way into public consciousness during the record-breaking heat wave of 1988, environmentalists have been pushing governments to take action. Auto engines, power plants and landfills spew out carbon dioxide, methane and other heat-trapping gases by the ton. Left unchecked, many scientists believe, the buildup in the atmosphere could create the greenhouse effect, boosting temperatures and changing weather patterns in unpredictable, probably destructive ways. At last year's Rio Earth Summit, world leaders agreed that emissions of greenhouse gases should be curbed, but at the insistence...
