...samples he had taken from the woman to his colleague Salo, the biochemist. Using a new technique of dna analysis called polymerase chain reaction, the Minnesota researchers cloned billions of copies of the ancient genetic material. Then they identified a fragment of dna that is found only in TB bacteria...
...Bacteria can survive in an enormous range of conditions and temperatures," Herschbach said. "I would be surprised if it takes more than two or three decades to find other forms of life in the universe...
...style protesters was a quintessentially '90s issue: whether a genetically engineered hormone that went on sale last week after nearly 10 years of legal wrangling threatens the safety of American milk. The hormone, a natural protein found in cows, is being artificially manufactured in vats of genetically altered bacteria. When cows are regularly given extra doses of the hormone, their milk production can rise as much as 15%. Scientists call the chemical bovine somatotropin (BST) or, more simply, bovine growth hormone (BGH), and it is marketed under the trade name Posilac...
...Outbreaks of Mycoplasma pneumoniae, a bacteria that causes a particularly virulent respiratory illness, have struck New York, Ohio and Texas. The cold- like bug could spread rapidly as winter approaches...
...another first for biotechnology, scientists have isolated a disease- resistant gene in one type of tomato, cloned it and inserted it into a variety of tomato that lacks that gene. The cloned gene signals the plant's defense system to ward off an invasion by bacteria that cause a leaf- destroying disease known as speck. Researchers predict that similar advances with other crops will significantly reduce the need for pesticides by the end of the century...
