Seen from space, the distant earth turned the thoughts of many astronauts to environmental problems. "I wondered how everyone is going to live on that small, crowded globe," recalls John Young of Apollo 10 and 16. Even during the tense hours after the explosion of an oxygen tank, Apollo 13's Jack Swigert found himself concerned with the terrestrial environment-and suddenly certain about how to preserve it: "I became convinced that space technology-earth-resources satellites, solar-energy generators, global communications networks and the like-is the answer to the environmental disasters that threaten this fragile earth...
...Linda Chiarello, 16, of New Providence, N.J., have different interests and career ambitions, the two earnest high school students also have something in common: a life-threatening genetic defect. Both suffer from Cooley's anemia (thalassemia major), a hereditary blood disease resulting in deficient synthesis of hemoglobin, the oxygen-carrying component of blood. Their condition causes cardiac and other complications that kill most of its victims in their teen-age years. The pale, often undersized youngsters may have bone deformities and enlarged spleens and livers; they tire easily and frequently miss school...
...past 400,000 years. His conclusion is based on cores of ocean sediment from the Caribbean. Composed of the remains of tiny sea animals, the layered sediment provides a record of climatic changes. When the oceans warm up, there is a decrease in the ratio of the isotope oxygen-18 to ordinary oxygen in the shells of the little creatures; when temperatures go down, the concentration of oxygen-18 goes up. Moreover, the proportions are preserved after the creatures die and sink to become layers of sediment. Thus, because these layers can now easily be dated, the shells...
...study reported that a change in metabolism observed during meditation corresponds to a deep balanced state of rest deeper even than sleep Specific body reactions such as a sharp fall in oxygen consumption and carbon dioxide elimination and a simultaneous reduction of the heart's workload scientifically explain the restful alertness" claimed by meditators...
...verge of solving one of its biggest coastal-pollution problems. Governor Tom McCall recently restricted the number of logs that could be stored on waters around timber-processing and pulp plants. The new policy is designed to reduce the bark and debris that, as they decompose, consume precious oxygen and thereby choke marine life. Says McCall's environmental chief, L.B. Day: "We think we can start harvesting oysters in Coos Bay in a couple of years...
