...manufacturers the hormone represents the dawn of a dazzling new era in agriculture. To its critics, however, it poses a dangerous threat to the prosperity of dairy farmers and the wholesome image of "nature's perfect food." The product is bovine somatotropin, a natural protein found in cattle that has been artificially mass-produced in the labs of several pharmaceutical firms. When injected into dairy cows, BST can increase their milk production up to 25%. But would the use of BST create a milk glut that could drive down dairy prices? And would consumers view milk from BST-treated cows...
...radio transmitters could not be located during the winter. Says Assistant Chief Ranger Gary Brown: "The bears don't seem to be frightened by fire. Poaching is a bigger threat by a long shot." The grizzlies will, however, find it more difficult to locate a crucial source of prehibernation protein, the whitebark pine nut. Though less than 20% of the whitebark pine trees in the park were burned, some scientists feel that a larger percentage of trees of nut-bearing age were killed. A shortage of the nuts could drive bears from higher altitudes this fall -- and into more confrontations...
Chiron's initial breakthrough was to isolate a viral protein from blood samples taken from patients with non-A, non-B hepatitis. By cloning large quantities of the protein, the company was able to develop a test to detect its presence in blood. Chiron called the pathogen the "hepatitis-C virus." In clinical studies done at the National Institutes of Health, the Centers for Disease Control and laboratories in Italy and Japan, blood samples from patients thought to have non-A, non-B hepatitis were screened using Chiron's test. At least 80% of the samples tested positive...

...patient's faulty gene. When the retrovirus invaded a marrow cell, it would insert itself into the cellular DNA, as retroviruses are wont to do, carrying the good gene with it. Reimplanted in the marrow, the altered marrow cells would take hold and multiply, churning out the previously lacking protein and curing the thalassemia patient...
