...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 are reported in the scientific literature. Molecular Biology of the Gene (second edition), Professor Watson...
...failed to survive medical scrutiny. "Athlete's heart" was practically pronounced dead in 1927, to the relief of the anxieties of many a long-distance runner. Ptomaine, long blamed for food poisoning, has been exposed as a fraud; most of its symptoms are now attributed to bacterial or viral infections, while the rest are the result of chemical contamination...
...nothing more than iron-deficiency anemia. Febricula, a "little fever" that lingered in some medical texts until 1947, was once thought to be caused by stale beer, foul odors and sewer gases. It has since been identified as a symptom of a variety of other-and more easily identified-viral infections of the respiratory tract...
...three researchers confirmed the fact that viral RNA material was indeed producing its own DNA. They labelled four chemical building blocks of DNA with a radioactive isotope of hydrogen called tritium. After mixing the building blocks with viral RNA, the "tracer" element appeared in what was chemically identified as DNA. Thus it was apparent that the RNA had assembled the blocks to form DNA in its own image...
Painful Choice. Another bug-this one viral-made the hours before liftoff almost as tense as the launch itself. The countdown for the mission was about to begin when Astronaut Charles Duke, of the Apollo 13 back-up crew, complained of chills, fever and a rash. Doctors diagnosed his illness as rubella, or German measles. Duke had apparently caught the disease from the children of friends. Dismayed NASA officials immediately ordered blood tests of Apollo 13's first-line crew members, who had come in contact with Duke during several preflight conferences. Both Astronauts Jim Lovell and Fred Haise...
