...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...
...twice a day (he lost 4 Ibs.), read the Bible, watched TV through a window in the 7-ft. diameter cone, slept only six hours a night but made up for it by lying on his back some twelve hours a day, doing nothing at all. Sheets of potassium superoxide absorbed his breath, removed the potentially poisonous carbon dioxide and released the fresh oxygen that he lived on all week. He came through so well that the space doctors are now at last ready to try the test in the weightless condition of actual space, first with animals, then with...
...this, tried griseofulvin against several deep-seated fungal infections. In all but one it failed. The exception was sporotrichosis, in which Sporotrichum schenckii attacks the lymph nodes and often causes hidden ulcers. In his first two patients treated with griseofulvin, he found the antibiotic as effective as the conventional potassium iodide treatment. Dr. González-Ochoa's conclusion: the idea that griseofulvin is useful only against surface infections is too glib; it should also be "tested against internal fungal infections, for some of which no cure is now known...
