...fast mountain rivers, are in general safely low in sodium. But some rivers are loaded with the stuff. The Arkansas River reaches 1,770 p.p.m. in the fall and cannot be used for drinking water. Moreover, a city's river water may be hard (because of calcium and magnesium carbonates), and housewives want it soft for washing; so the engineers soften it, often by replacing the calcium with sodium. One eminent cardiologist at a Midwestern hospital was puzzled when his heart-failure patients suddenly got worse and proved harder to treat. The hospital engineer, without telling the medical staff...
...land has a fierce and lonely beauty all its own-windswept plateaus, shifting seas of sand, canyons slashing down through layers of sandstone, and, always on the far horizon, mountains of barren granite. Beneath the ground is a fabulous treasure of coal, oil, sodium, magnesium, potassium, uranium. Coursing through the entire region-from Wyoming to Utah and Colorado, on to Arizona, New Mexico and California-is one of the greatest of U.S. river systems. Starting as a trickle in the Rocky Mountains, the Colorado River sweeps south and west to absorb such tributaries as the Gunnison River, the Roaring Fork...
...with highway signs to match, U.S. motorists would lave less trouble finding their way through superhighway mazes. Hercules Powder Co., pioneer producer of polypropylene, has developed a new glass-and-plastic material for a third-stage shell for the Minuteman missile. It is trans lucent, as light as magnesium and stronger than steel...
...other high-energy chemicals out of water and carbon diox ide. They have known for more than one century that this vital food-making process-photosynthesis, the prime mover of life on eartn-is accompusned by chlorophyll, a strange, green substance whose molecule has a single atom of magnesium framed like a jewel in its center. Generations of chemists have tried to synthesize chlorophyll-and failed. But last week Harvard University announced that Professor Robert Burns Woodward, 43, already famed for synthesizing quinine, cortisone and strychnine, had turned the historic trick: he had built genuine chlorophyll-a, the kind that...
Differences in racial stock, diet, occupation and living habits offer no explanation, Dr. Schroeder believes. And though he feels that something in the water may be responsible, the precise ingredient eludes him. The evidence excludes practically all the known factors: iron, manganese, sodium, potassium, magnesium, calcium, carbonates, sulfates and nitrates, and a variety of softening agents. Also -and most important from the public-health standpoint-it shows that addition of chlorine and fluorides has no effect on heart-artery disease. One clue: the more alkaline the water, the greater the protective effect on human arteries. This may be because more...
