...election of the President, Vice President, Senate and House of Representatives. Other proposals before the Congress would include state and local elections in the lowered age group. - Ordered a ban on the production and use of military toxins, which are dead but poisonous products of bacteria. He had earlier renounced the use of bacteriological warfare but had left the status of toxins in doubt. - Urged the Senate to ratify a long-pending agreement worked out in the United Nations that would make genocide an international crime. The proposal has been languishing in the Senate since 1950, hung up in part...
...film. Fluoridated toothpastes have won the approval of the American Dental Association (though not of all individual dentists) as a useful adjunct to water fluoridation. Another possibility, on which the National Institute of Dental Research is working, is the development of an antibiotic that would selectively keep down the bacteria known to be a major factor in the beginning of decay. Such a discovery may be years away. Meanwhile, water fluoridation remains the most effective, safest and cheapest shield against cavities. At 10$ psr person a year, it would cost $13 million to fluoridate all remaining public water supplies...
...known life in the universe. At least 400 million years ago, some primeval accident allowed plant life to enrich the atmosphere to a life-supporting mixture of 20% oxygen, plus nitrogen, argon, carbon dioxide and water vapor. With uncanny precision, the mixture was then maintained by plants, animals and bacteria, which used and returned the gases at equal rates. The result is a closed system, a balanced cycle in which nothing is wasted and everything counts...
...maintain balance, all ecosystems require four basic elements: 1) inorganic substances (gases, minerals, compounds); 2) "producer" plants, which convert the substances into food; 3) animal "consumers," which use the food; and 4) "decomposers" (bacteria and fungi), which turn dead protoplasm into usable substances for the producers. As the key producers, green plants alone have the power to harness the sun's energy and combine it with elements from air, water and rocks into living tissue?the vegetation that sustains animals, which in turn add their wastes and corpses to natural decay. It is nature's efficient reuse of the decay...
...More than 300 cases were recorded, two-thirds of them severe enough to require hospital treatment. Virtually all of the physical symptoms fitted the concept of an infectious disease: headache, sore throat, malaise, dizziness, nausea and vomiting, diarrhea. Since the Royal Free's expert microbiologists could find no bacteria to blame, they concluded that the cause of the outbreak was an even smaller and more elusive germ, an unidentified virus...
