...chemical, which according to state lexicologists is only one twenty-fifth as toxic as the pesticide used in flea collars. Brown's fears notwithstanding, state officials said it was safer to spray from the air than the ground. Reason: the Malathion is mixed with molasses, sugar and yeast and falls in coffee-graint-size droplets that cannot be easily inhaled. B.T. Collins, 40, director of the California Conservation Corps, gave the most dramatic demonstration of its safety: he drank a glassful of Malathion diluted with water to the concentration used in the spray...
...went public and jumped $45 per share during its first day on the market. The slightest technological advance still sends prices leaping. Genentech jumped $7 in one day two weeks ago when workers announced a new process to make interferon, a supposed cancer-fighting protein. Genentech will now use yeast to produce the human protein rather than bacteria. It doesn't seem like a major change, but two advantages come with this adjustment. First, yeast are especially suited to high-volume production (they have been used to make beer for hundreds of years). Also, yeast don't produce a toxic...
...present, nitrogen must be provided in expensive fertilizers made from increasingly costly petroleum products. But scientists using plasmids have already cloned some of the nitrogen-fixing genes found in bacteria. And in an experiment at Cornell, a complete set of 17 such genes was transferred from bacteria to yeast, a slightly higher organism. The ultimate goal: to insert these genes in the plants themselves...
...According to the Soviets, the experiments included physiological and biological stress tests, notably monitoring the skeletal changes that occur during prolonged exposure to weightlessness. The cosmonauts made extensive surveys of the earth, looking for oil deposits, checking crops and forests, and seeking untapped sources of fresh water. They cultured yeast cells and grew layers of gallium arsenide crystals, an important component of computer chips and lasers. The objective: to test the zero g environment for possible use in future space manufacturing facilities...
...disease is abstinence from sex or at the very least a high degree of sexual selectivity. Condoms may reduce the risk of infection. One thing that will surely help is better informed physicians. Says one Seattle doctor: "A lot of women and doctors believe everything down there is a yeast infection." To reduce misinformation about herpes, the American Social Health Association of Palo Alto, Calif, distributes a newsletter called The Helper and is setting up HELP chapters around...
