Interest in possible viral causes of cancer peaked in the 1960s, when various animal studies suggested that viruses could cause turnors. But apart from rare correlations (such as that between the Herpes simplex II virus and cervical cancer in women), researchers could not establish a general cause and effect relationship between viruses and cancer. Recent advances in the field of genetic engineering have paralleled a surge of interest in the possibility of a genetic cause of cancer. But apart from circumstancial evidence for genetic causes of such rare cancers as Burkitt's lymphoma (as Harvard recently announced), the possibility...
...Both viral and genetic approaches to cancer research share one flaw--they attack not the cause of cancer but its mechanism. Even proponents of genetic and viral theories concede that something external must trigger malignant cell growth. These researchers accept the existence of cancer-causing substances in the environment as a given, and devote their efforts to reversing the cancer cycle once it has started--not preventing it from starting. Rather than investigating whether cigarettes, saccharin, asbestos or other hazards should in fact be banned--or going further and lobbying to ban them--such researchers seem to feel helpless...
...which produce extremely faint images in an electron microscope. If they are subjected to extra-long exposures in the electron beams or are stained to improve contrast, their structure becomes distorted. Klug overcame this major obstacle by manipulating the images mathematically with the help of a computer. Among the viral structures discovered by his new method was that of a common plant blight: the tobacco mosaic virus, a tiny rod-shaped particle consisting of a single-stranded coil of RNA surrounded by a cover of protein that resembles a stack of discs...
DIED. Marcus Wallenberg, 82, head of the most powerful banking and industrial dynasty in Sweden and co-founder in 1972 of the Skandinaviska Enskilda Bank, now the most influential commercial bank in Sweden; of a viral infection; in Djurgården, Sweden. Part of the third generation of Wallenberg bankers who have been synonymous with Swedish business for more than a century, Marcus and his brother Jacob (who died two years ago) rebuilt Sweden's industrial strength after the Kreuger crash in 1932. Eventually taking control of such multinational giants as Electrolux, L.M. Ericsson and Saab-Scania, Wallenberg also...
Since there is no cure, frustrated herpes sufferers will try almost any potion or palliative. Some herpetics regularly consume buttermilk, vitamins, herbs or lysine, an amino acid that is said to help retard viral growth. Some avoid eating chocolate, nuts and other foods containing arginine, another amino acid that some specialists think encourages viruses. Other patients apply seaweed, earwax, snake venom, peanut butter, watermelon, ether, baking soda, bleach, yogurt compresses, carburetor fluid or Instant Ocean, an aquarium product that they lace into their bath water. None of these home remedies is a cure, but sufferers keep experimenting. Says Dr. John...
