...overcome this obstacle, the NIH researchers-Drs. Brian Murphy, Elias Chalhub and Robert Chanock and Biologist Sandra Nusinoff-decided to beat the virus at its own flexible game. Vaccines now in use are made with a type of virus that has been killed and therefore has only limited ability to stimulate the body's immunological system. The new vaccine uses a combination of live viruses that brings about a stronger immune reaction. These active (though weakened) agents can also be grown in cultures more quickly, giving scientists a better chance of staying even with the most recent flu threat...

...major reason is that the park areas have been so carefully protected from fire that the pines have become aged and thus vulnerable. Now millions of them are turning bright red and then gray as they die. Says Yellowstone Biologist Doug Houston: "The longer you suppress fires, the more we set ourselves up for insect infestation and for unnatural catastrophic fires...
...Grand Teton, the Park Service plans a highly visible burn near Jackson Hole, Wyo., to test public reaction and begin the re-education process. Says Grand Teton Research Biologist Lloyd Loope: "We haven't so much an epidemic of mountain pine beetles as of overmature lodgepole pines." He warns that if the policy of putting out all fires is continued, there will be periodic insect infestations, like the endemic pine beetle problem, as well as a decrease in the diversity of p.ants, animals and birds. Loope believes that allowing natural fires to burn...
...weight of beef cattle, and a comparable increase in milk production-for a cow that is being bled by vampires may yield only 20 quarts of milk a day as against a normal 30. There is no danger of the vampire's becoming extinct, says Mexican Biologist Raul Flores Crespo. "We can reduce the population, but we cannot totally destroy it. The vampire can return to the jungle and live as it did before the coming of the Spanish." That is, by sucking on wild animals but not on horses and cows...
