Brave words-and in a sense, incredibly true. On that late winter day in 1953, the two unknown scientists had finally worked out the double-helical shape of deoxyribonucleic acid, or DNA. In DNA's famed spiral-staircase structure are hidden the mysteries of heredity, of growth, of disease and aging-and in higher creatures like man, perhaps intelligence and memory. As the basic ingredient of the genes in the cells of all living organisms, DNA is truly the master molecule of life...
...Crick, a 36-year-old dropout from physics who had developed a belated interest in biochemistry, announced the solution to a puzzle that had stymied the scientific world. Though neither was especially equipped by training or experience for so challenging a task, they had unraveled the structure of deoxyribonucleic acid, or DNA, the basic molecule of heredity...
...discussed the activity of small proteins that somehow attach themselves to the coils of DNA and control how the molecule replicates. Nobel Laureates David Baltimore of M.I.T. and Howard Temin of the University of Wisconsin reported on the use of viruses, which are little more than coils of nucleic acid wrapped in protein, to transfer new DNA or its molecular cousin, RNA (for ribonucleic acid), into bacterial cells. In the process, the cells are genetically transformed...
...smog that envelops Athens for most of the year. Called the nefos (literally, cloud), it is composed mainly of sulfur dioxide, a waste product given off when petroleum is burned in autos, factories and residential furnaces. As rain and dew mix with the SO2, they form a weak sulfuric acid that turns marble into crumbling plaster...
Five caryatids of the Erechtheum, which support carvings that acid rains have obliterated, were replaced temporarily with plaster likenesses. The original caryatids have been taken to the Acropolis Museum, where they will be placed in a glass chamber filled with nitrogen, a gas that acts as a preservative...
