MOST public interest in basic science research falls on individual experiments and the men who perform them. In the last few years, however, the entire field of molecular genetic has attracted an aura of scientific glamour. Newspaper stories about the isolation of the gene, genetic engineering, and "the secret of life itself" arouse the public's curiosity, and recent major advances in cancer and leukemia viral research excite even medical professionals. Research workers in molecular genetics are acutely aware of the implications of their work, of course, but usually prefer to separate personal reflections from the experimental observations that...
Five years ago, Professor Watson wrote the first edition of Molecular Biology of the Gene, a comprehensive summary of work done in molecular genetics up to that time. But Watson included numerous predictions and assumptions that gave the book a personal, non-textbook character. In his 1965 preface, Watson wrote...
...second edition of Molecular Biology of the Gene, Watson has improved the first edition by adding 150 pages of new information and by changing some parts of the first edition which recent work has shown to be inaccurate. The style, however, has not changed. Watson still includes personal comments where needed to propose a complete picture of his topic where the known facts present only a skeleton. For example, when discussing ribosomal structure, Watson says that "not even a semi-satisfactory hypothesis now exists for why ribosomes contain rRNA as well as protein." Nevertheless, in the next few sentences, Watson...
...theory that learning and memory are dependent on molecular chemical groupings and regroupings seems more promising. Halacy surveys the major researches in this area, including controversial experiments in which trained flatworms were minced and fed to untrained flatworms. In equally controversial tests, the latter apparently cannibalized the former's acquired knowledge, which is believed to have been contained in RNA molecules that were coded during training. As late as the mid-'60s, chemicals such as glutamic acid were thought to increase alertness in humans and even to boost IQ scores. Alas, the latest word from the lab seems...
...violent action is low, is it due to a gross cerebral defect, such as a tumor? Or is it the result of progressive environmental influences, such as living in a lower-class urban environment or watching violent television programs, which might create a cerebral predisposition to violence on a molecular (memory-bank) level...
