...with genetic engineering-attempts to alter the program of the cell by changing the coding on the DNA molecule. But nongenetic theories will probably pay off sooner. One current favorite holds that aging occurs because certain giant molecules in human cells eventually get bound together. These immobile aggregations clog the cells, reduce their efficiency and eventually cause them to die. In Wisconsin, Dr. Johan Bjorksten is trying to find suitable enzymes, most likely from soil bacteria, that will reduce these massed molecules to small fragments that could be excreted from the cells. Such enzymes would probably be injected daily into...
...airlines are not ignoring complaints about crowding when planes fly close to capacity. Pan Am is contemplating discarding the food-service wagons that clog the aisles. Continental Airlines, which began 747 service on the Los Angeles-Honolulu run two weeks ago, reduced its seating capacity from 360 to 335. Using the extra space, it added a tourist-class bar and lounge in the tail...
...Opposition to any duly elected government's acts can come only from those who have elected it and feel their mandate has been misinterpreted. And even they-men and women of age and position -cannot take it upon themselves to claim they are the majority just because they clog squares and streets...
...more varieties of plastics that can be burned, provided the local air-pollution code allows the hospital to use an incinerator. But the PVC (polyvinyl chloride) plastics may generate lethal fumes containing hydrochloric acid and phosgene, a poisonous gas once used in chemical warfare. Other plastics melt and clog the incinerators...
...trouble with modern plastics is that they seem to be as immortal as they are useful. Plastic garbage bags litter Italy; Florida's discarded containers clog Bahama beaches. Each year one Kansas plant makes enough cellophane to wrap the earth with a 15-inch band 40 times; most of it becomes enduring garbage. Even getting rid of plastics can be dangerous. When polyvinyls like Saran Wrap are burned, they produce corrosive hydrochloric acid...
