...strain may be less effective against a genetic variant that appears later in the same season. If appropriate inoculations could always be prepared in advance, doctors would have been able to prevent the outbreak of A/Victoria flu this winter among Fort Dix recruits-who were vaccinated against three other viral strains. Admits Virologist Gary Noble of the U.S. Public Health Service's Center for Disease Control: "Ford made the vaccine sound a little rosier than...
...only from the A/Victoria influenza virus, a strain that caused last winter's relatively mild flu epidemic. But tests showed that at least a dozen of the soldiers-including an 18-year-old who died of flu-related pneumonia-had been infected with a new and more worrisome viral strain. Medical experts are concerned that the virus, usually seen only in swine, may be similar to the lethal virus that probably caused some 20 million deaths-including 548,000 in the U.S.-during the great global flu "pandemic...
Before discoveries made by this trio, doctors knew that viruses could enter a cell, seize control of its machinery and force it to reproduce copies of the viral invaders. Dulbecco, an Italian now working in London, demonstrated that the invaded cell's descendants showed the influence of the viral genes as well as its own. Temin, of the University of Wisconsin, and Baltimore, of Massachusetts Institute of Technology, shattered what had been the central dogma of genetics: the belief that the master molecule DNA always passed information along to the messenger molecule RNA. The two researchers proved that...
Even if it is proved that viruses cause human cancer, cautions Spiegelman, it may be years before science can develop a safe, successful vaccine against them. But identification of cancer viruses is likely to produce a payoff long before vaccines become practical. Spiegelman believes that the presence of viral particles, which are unique to each type of cancer, may provide doctors with effective methods of detecting cancer in its earliest stages-well before it can be diagnosed by X rays and more conventional methods. That development by itself could save many of the Americans who die of cancer every year...
...confirmed by the Vatican's Sacred Congregation of Rites. Confirmation of two additional miracles is usually required for canonization; in Mother Seton's case, however, Pope Paul decided that one would suffice. It occurred in 1963 when Carl Kalin, a construction worker, was stricken with a complicated viral affliction of the brain...
