...brain; it forms the basis of the Wurtman-Zervas theory. The two neuroscientists speculate that cells starved of oxygen as the result of strokes die and allow their stored dopamine to escape. Dopamine is normally released only in minuscule amounts, and a sudden flood of the chemical can be lethal. Excess dopamine can cause nearby blood vessels to contract, cutting off oxygen to neighboring cells and thus spreading the stroke damage. After the flood has subsided, there is a serious shortage of the dopamine; the cells killed by the stroke are no longer producing it. Result: the lack of coordination...
WASTES. After the nuclear fuel is used, the remaining liquid wastes are not only radioactive but long-lived. Indeed, radioisotopes of plutonium 239 will remain lethal for at least 250,000 years. The AEC is sure that it can handle the problem by solidifying the wastes (so that they cannot enter the environment) and then keeping them under surveillance until a safe storage technique is developed. But, says Physicist Henry Kendall, "the legacy to future generations very much disturbs...
...Hell's Angels on their Harley-Davidsons turned in convincing performances as Visigoths at the gates of suburbia. Easy Rider could not keep off the grass, and Evel Knievel, that star spangled Icarus of the carnival circuit, gives young minibike owners potentially lethal delusions of grandeur. But now, during the lull in the great gas panic of '74, comes a 46-year-old Minnesotan and writer of computer manuals, who makes the motorcycle not only respectable but also a focus of mental and spiritual health...
...JANUARY 1972, the U.S. Surgeon General published a report that both worried and pleased many who do not smoke cigarettes. The report said that a burning cigarette can be as lethal for the non-smoker who breathes it as for the smoker who puffs it. This worried nonsmokers, of course, because it confirmed that all the health hazards the Surgeon General warned smokers about in his famous 1964 report--lung cancer, heart disease, emphysema and the rest--were hazards they faced as well, merely because they lived and worked with smokers. But the 1972 report also pleased non-smokers: Here...
Unreconstructed intelligence men protest that this is no way for a secret organization to behave. They argue that the BND can now be infiltrated by counterspies armed with nothing more lethal than an application form. One answer to that, of course, is that the BND was unable to keep out double agents even when it was most secretive. To Gehlen's embarrassment, in the 1950s the Soviets stocked his organization with so many former SS intelligence men that Moscow had to do its own personnel work. When too many counterspies became concentrated in certain BND departments, the Kremlin pressured...
