...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...
Cookies, Too. Pilgrim believes that on short space jaunts the crewmen will breathe bottled oxygen. For longer voyages, a chemical recycling system that Boeing has developed looks more practical. It uses potassium or sodium super-oxide to generate oxygen and absorb CO2. Only on very long voyages, the sort that are measured in years, will closed systems using algae be the most efficient. On such space ventures, the crew may even be able to eat the excess algae (Pilgrim's daughter Vicki Leigh, 15, has made acceptable cookies of them), eliminating much of the need for toting food...
...Columbia biochemists proved that the same reaction that takes place at the synapse is repeated all along the length of the nerve. When a nerve is stimulated, a chemical called acetylcholine is released within the nerve. It combines with the receptor protein, causing an interchange of sodium and potassium ions. The ions in turn trigger release of more acetylcholine a bit farther along the line, letting the current advance. To turn off the signal, an enzyme, cholinesterase, is released that instantly destroys the acetylcholine in the nerve...
...fall into unemployment." Greatly increased yields can be obtained by such simple devices as an improved plow, which could be drawn by a bullock, or by increased use of fertilizer. "Just as most people are starved for food, most crops are starved of essential elements-nitro gen, phosphorus and potassium." Though production of nitrogen fertilizer has now reached 10 million tons a year, it "still ranks as one of the most underexploited discoveries of all time." Concluded Britain's Physicist P.M.S. Blackett: "We as scientists and technologists, have already given ourselves the tools by means of which hunger could...
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...
