Beams of electrons have long been used to study the structural details of tiny organisms, but DNA and RNA, the molecules of the genes, do not lend themselves to such inspection. They consist mainly of light, simple atoms, which produce extremely faint images in an electron microscope. If they are subjected to extra-long exposures in the electron beams or are stained to improve contrast, their structure becomes distorted. Klug overcame this major obstacle by manipulating the images mathematically with the help of a computer. Among the viral structures discovered by his new method was that of a common plant...
...Howard Hughes, letting our fingernails grow toward heaven in prayers for a germproof sterility. That we do neither is as remarkable in its way as the Tylenol poisoning itself. The poisoning is, to put it mildly, an aspect of extreme behavior. One might think that its antidote would also consist of extreme behavior. But instead, all the public does in response to this hitherto unseen monster is to rely on several old, familiar investigative mechanisms: the testimony of experts, the advice of the Food and Drug Administration, the news reports and, of course, its own capacity to make sense...
...other bones, uncovered about half a mile away from White's find, consist of seven skull fragments, all lying within 18 in. of one another. The discoverer was another expedition member, Leonard Krishtalka of Pittsburgh's Carnegie Museum. Remarkably, three of the fossils, including a frontal bone, which is especially useful in assessing the possible shape of the skull, easily fit together. The age of the bones was determined from radioactive dating of a layer of cindery volcanic debris near the fossils. The bones, declared Clark, are the oldest clearly identifiable hominid, or humanlike, skull fragments ever found...
Beyond the Ivory Tower's cost is $15.95; its benefits consist of an original approach to the vexing problems faced by private universities. The synthesis struck is animated by a genuine and admirable belief in progress. How odd that its effect is a resounding defense of the status quo at Harvard...
Christianity is also shifting in denominational terms. The fastest growing category is what Barrett labels nonwhite indigenous churches. Including Africans not tied to Western missions, these groups by the year 2000 will number 154 million. The biggest distinct category of Protestants today does not consist of traditional Reformation groups, such as the Lutherans, but the Pentecostalists-at 51 million strong, a leading strain of the worldwide Evangelical movement. In addition, 11 million members of more traditional denominations follow Pentecostal practices. Barrett's astounding conclusion: the Evangelicals, taken all together, today command a healthy majority of Protestants in the world...
