...when brother and sister are reconciled in a scene that conveys forcefully the author's tragicomic sense of life. Even Dr. Braun, the scientist, is "bitterly moved" by the "crude circus of feeling"-but not so moved that it prevents him from trying to explain human emotions in molecular and cosmic metaphors...
...inherited features from one generation to the next. And one of the greatest of man's scientific triumphs has been the discovery of the method by which the genes transmit and translate the message of heredity. Last week, for their ingenious work in breaking the genetic code, U.S. Molecular Biologists Marshall Nirenberg, 41, Har Gobind Khorana, 46, and Robert Holley, 46, were jointly awarded the 1968 Nobel prize for physiology and medicine...
...their accomplishments the three new U.S. Nobelmen have not only provided a clearer understanding of the nature of life, they have brought closer the day when molecular biologists will be able to correct genetic defects, control heredity, and perhaps even create life itself...
This summer Epstein used federal and foundation grants to hold month-long seminars at Tufts University for 13 Negro teachers of molecular biology and physiology. He also brought in ten black freshmen from Tennessee A. & I. to take the experimental course. They came to understand the papers as well as his students at Brandeis, Epstein discovered, and they did so faster. This is partly because the method places more emphasis on understanding the scientists' techniques than on reading comprehension. One girl even suggested an experimental technique similar to one that had led to a breakthrough in molecular genetics...
Bizarre Scheme. Perutz studied molecular structure by analyzing X-ray photographs of crystallized hemoglobin. Scattered and deflected by the atoms within, the X-rays form a pattern of light and dark spots on a film behind the crystal. By patient mathematical analysis of thousands of variations of this pattern (each produced by a Perutz technique of substituting mercury "tag" atoms for different atoms within the hemoglobin molecule), the structure of the complex molecule was carefully pieced together...
