Desirable genes are transferred into tissues which have been removed from patients. The altered, hardier tissue is then reinserted into the patient. If the procedure succeeds, the patients will begin to produce the new protein as though it had always been part of their...
...Wednesday, an hour before the first pitch of the season, in Kansas City. "Five bluegrass types-Princeton 104, Eclipse, Nassau, Glade and Suffolk-and four ryes-Derby, Gator, Regal and Top Hat. They act like a team. If one or two get sick, the others take over. Some are hardier than others; some are greener. That's why we have nine. Come to think of it, that's one grass for every position on the field...
...infection is entirely cleared up. That suppresses susceptible microbes but allows partially resistant ones to flourish. People with viral infections sometimes demand antibiotics, even though the drugs are useless against viruses. This, too, weeds out whatever susceptible bacteria are lurking in their bodies and promotes the growth of their hardier brethren. In many countries, antibiotics are available over the counter, which lets patients diagnose and dose themselves, often inappropriately. And high-tech farmers have learned that mixing low doses of antibiotics into cattle feed makes the animals grow larger. (Reason: energy they would otherwise put into fighting infections goes | into...
...booster would argue that the bioengineering of farm animals and plants poses no risks. With plants, for instance, there is always the possibility that new traits could be accidentally transferred to wild relatives of domestic species. Theoretically, experiments with genes that confer resistance to disease or herbicides could create hardier weeds. Food safety is another legitimate concern. Products from genetically altered crops and livestock will require rigorous testing to ensure that they are harmless...
...Harrisville, N.H., the Elm Research Institute has funded a project headed by Dr. Eugene Smalley of the University of Wisconsin to come up with a hardier elm. The tree is called the American Liberty Elm (after a famed Massachusetts tree under which George Washington purportedly took command of the Continental Army in 1775). The American Liberty has a smaller cell structure that prevents Dutch elm disease from spreading through the tree's vascular system. So far, Elm Research has distributed 75,000 of the new trees for prices ranging from $ $2 to $5 each, a good start on its target...
