...possible full-scale flight from the region? The first explanation came from NRC officials. They said the reactor had unexpectedly developed an 880-cu.-ft. gas bubble, which was compressed between the water covering the reactor's core and the top of its steel housing. Acting like a lid on a pressure cooker, the bubble was maintaining high temperatures and pressures. NRC officials warned that there was a very remote but frightening possibility that the bubble would grow big enough to block the flow of water. In that case, the temperature in the core could rise high enough (3,000?...
...precedent that might be set by a coup d'état-the first for the English-speaking islands of the area. Barbados, Jamaica, Dominica, Guyana and St. Lucia issued a stuffily worded statement that the coup had been "contrary to the traditional method of changing governments" in the region...
...Lars Terenius of Uppsala, Sweden, announced almost simultaneously the discovery of specific receptors for such opiates in the brain. Snyder's lab located a high density of receptors in the medial thalamus, an area of the brain responsible for registering deep sustained pain; in the amygdala, a region of the brain's limbic system that plays a role in controlling emotion; and in the spinal cord...
...mind chemicals also hold promise for controlling emotional pain. Because the emotion-controlling amygdala region of the brain is rich in enkephalin receptors, scientists speculate that the molecules may act as a defense against disappointments and trauma. At the Salk Institute, Floyd Bloom is studying the possibility that endorphins may be involved in the pleasure received from alcohol and opiates. Once a person begins taking heroin, say, the natural production of endorphins may decrease. Thus, if addicts try to go cold turkey, the agony of withdrawal is severe. If scientists can create nonaddictive chemicals that bind, like the opiates...
...Peking late last week, Chairman Hua Guofeng (Hua Kuo-feng) announced that the Chinese withdrawal had been completed. Hanoi, however, contended that Chinese troops still occupied sections of one Vietnamese border province. This point was supported by diplomats in the region who felt Peking wanted to maintain control of what had been "disputed territory" along the 735-mile frontier...
