...animal. And the un skilled farm labor needed for the simplified job would earn only about $2.50 per hour, sharply reducing costs to the wool industry. Taking up the project at Terrill's suggestion, Agriculture Biologist Ethel Dolnick and Physiologist Ivan Lindahl began feeding varying amounts of a nitrogen-mustard anti-tumor drug to experimental sheep...
...single outward-swinging hatch that can be opened in 10 sec. To snuff out any fire that might start, there is now an emergency venting system that can reduce cabin pressure in seconds. And while the spacecraft is on the pad, a mixture of 60% oxygen and 40% nitrogen has been substituted for the 100% oxygen of flight, further reducing the danger of fire...
Then, as results came in from experimental plantings two years ago, the miracle proved highly vulnerable to such mundane enemies as bacteria, blight and insects. It required expensive nitrogen fertilization and often broke during milling. Many Asians, who prefer their rice sticky and manageable in the bowl, found IR8 too starchy and dry. Indonesians, in particular, complained because the stubby IR8 stalks had to be cut with a larger blade than could be concealed in the hand. That, they felt, offended their rice goddess...
These organic compounds made of carbon, nitrogen, hydrogen and oxygen resemble ordinary liquids. Yet their orderly molecular structure is similar to that of solid crystals such as diamonds, mica and quartz. The crystals themselves are not new, but it was only recently that scientists discovered that an electrical charge makes them light-reflecting; the higher the voltage, the greater the reflecting power. At first, this "electro-optical effect" could be shown only in the laboratory, since the crystals reacted to electricity only at certain temperatures. Now, after trying more than 100 compounds, RCA scientists have produced a crystal that responds...
...primitive organisms that consumed oxygen as fast as green plants manufactured it. Only by some primeval accident were the greedy organisms buried in sedimentary rock (as the source of crude oil, for example), thus permitting the atmosphere to become enriched to a life-sustaining mix of 20% oxygen, plus nitrogen, argon, carbon dioxide and water vapor. With miraculous precision, the mix was then maintained by plants, animals and bacteria, which used and returned the gases at equal rates. About 70% of the earth's oxygen is thus produced by ocean phytoplankton: passively floating plants. All this modulated temperatures, curbed...
