Cloning farm animals from embryos is pretty easy; cattle breeders have been doing it for years. Cloning from full-grown mammals is more difficult, but in the two years since Dolly showed that it was possible, scientists have managed to clone other sheep, mice and even cows, starting with a variety of adult donor tissue. Last week Japanese scientists unveiled what may be the most painless way yet to clone a cow: they produced two healthy Holstein calves from their mother's milk...
...cows were cloned using residual mammary cells found in the yellowish foremilk, or colostrum, produced when a cow gives birth. Scientists from Tokyo-based Snow Brand Milk Products gathered up some of these cells and gave them the Dolly-the-sheep treatment: transplanting their DNA into hollowed-out eggs and inserting the resulting embryos into the wombs of surrogate cows. Mammary cells were also used to produce Dolly, but they were scraped from the udder of an adult sheep. The Japanese scientists believe their kinder, gentler technique will make it easier to clone high-milk-yielding "supercows" by reducing...
...Madame Castafiore, a campy opera diva whose path he crosses several times). And to complicate matters further, he's constantly having quasi homoerotic relationships with young boys whom he befriends in foreign countries. Tintin's physical appearance is itself gender-ambiguous. What are we to make of his distinctive cow lick, which is neither particularly masculine or feminine...
...additional concern is genuine fear, and as in most cases where the emotion rears up, it is difficult to quell. "European consumers," says Dowell, "are genuinely concerned about both genetically engineered foods and those that are treated with hormones." The recent scares over mad cow disease have only reinforced the European concern over anything that might be considered potentially suspect in foods. European solutions -- such as specially labeling hormone-treated meats -- have been rebuffed by the U.S. as just another means of keeping European consumers from buying American. The latest scientific report is now expected to reignite the seemingly endless...
...mythological purple cow symbolically links Williams to its rural surroundings: we are about as far as we can be from Boston and still be in the same state, and Vermont is 10 minutes away. This can be an asset or a disadvantage, depending on what you like...
