...cultivation of the grape is an art which began over 5,000 years ago in Europe. Grapes grown in the United States today are descendants of these ancient stocks, although they have been grafted to hardier American varieties, according to the California Grape Commission...
...good one, but time and again it failed--just as it had failed for other scientists who had tried similar methods. On one trial, however, the Atlanta team happened to extract the eggs on the eighth day of the hormone regimen rather than the 10th. When these younger, presumably hardier ova were frozen and thawed, they emerged from the process intact.

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.

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...
