...garbage that infest ghetto slums. Yet both DDT and rats directly degrade the quality of U.S. life. Nevertheless, some aspects of the environmental problem are clearly more pressing than others. For example, public-health and land-use planning should rank higher than campaigns against litter and noise. Curbing carbon monoxide in cities is more important than saving caribou in Alaska. For environmentalists, the new challenge is how to retain ecology's holistic view of man and nature while yet recognizing that the movement will soon fade unless it sets priorities that millions of Americans can understand and support...
...civil engineers at New York University, Alan H. Molof and Matthew M. Zuckerman, tested their method at a $69,962 pilot plant in New Rochelle, N.Y. They send sewage through an alkaline solution that breaks down large organic molecules. Then all the small molecules are adsorbed on activated carbon, a purifying material used in cigarette filters and gas masks. "Though the process needs to be perfected, it promises to be at least one-third cheaper than tertiary treatment," says Dr. Molof. "But its biggest advantage is that it produces absolutely clean water-not less-dirty water...
...molecules into various synthetic ring-shaped, larger molecules called "holders," which are in effect chemical vises. After many attempts, they hit upon a holder that gripped the ethyl alcohol and acetic acid so that they were properly oriented for combination; thus when the molecules met, their reacting oxygen and carbon atoms were always at the correct angle for electron snaring-and the reaction took place a million times faster. By "steering" the individual atoms, Koshland concluded, the holder molecule had apparently duplicated the exact role of an enzyme...
...total volume of water which runs over the surface of the U.S. in a year." The devastating effect of that hot water on man and nature, the scientists did not bother to describe. But half those plants (running on conventional fuels) would gush 8.75 billion tons of carbon dioxide into the atmosphere each year-enough to change the globe's climate. The other half (nuclear powered) would increase the level of background radiation by as much as 2% a year-enough to have "unforeseeable effects on the world's living things, including...
...Intrepid's center steering wheel has been replaced by two wheels on either side of the cockpit, allowing the skipper to vary his vantage point. In addition to the two-wheel drive, Chance plans to add a lighter boom partly made of a new space-age material called carbon-fiber. HERITAGE is the first 12-meter designed, constructed, sponsored and skippered by one man. He is Charles Morgan Jr., a Florida yacht-builder and an experienced ocean racer. Though his do-it-yourself venture extends to cutting his own sails, he likes to call...
