...most rudimentary understanding of the workings of the living, changing cell is enormously difficult. It would be even harder without a new tool: nitrogen 15, a stable (nonradioactive) isotope of nitrogen. Chemically, nitrogen 15 is exactly like the common nitrogen 14. The cells cannot tell the difference. But since it is slightly heavier, nitrogen 15 can be measured accurately by a balky and expensive instrument called a mass spectrometer. If compounds containing nitrogen 15 instead of ordinary nitrogen are fed to cells, the scientists can tell with the mass spectrometer whether the cells have accepted them as food...
...these methods fail, there are plenty of other viruses to try against cancer. Some of them, comparatively harmless to normal human tissue, may attack tumors. If some such virus could be found or developed, it would be an ideal anti-cancer drug. Circulating through the body like a ferret through rat holes, it could hunt down every gangster cell...
...removed the patient's normal thyroid and with it the original cancer. This left the metastases which, they found, often consisted of cancer cells that retained faint remnants of the normal function of the thyroid. With the normal thyroid gone, the degenerate cells awoke and began to act like thyroids. Stimulated by the proper drugs, they began taking up iodine and making it into thyroid hormones. Then Dr. Marinelli gave radioactive iodine to the patient. The tumors, acting as pinchhitting thyroid glands, absorbed it readily, and were in some cases destroyed by the iodine's radiation...
...mammoth was a baby perhaps only a few days old. It was still bald, like its relatives, the modern elephants, rather than hairy like its own parents. It stood about 3 ft. high and weighed more than 200 lbs. One day, some 15,000 years ago, something happened to the baby mammoth. It may have stumbled into a bog or into quicksand, and been unable to get out. Perhaps the bank of a prehistoric river caved in on it. It sank down into the cold, Pleistocene mud, which kept out the air and preserved the body. With the coming...
...gallon. Even in textiles, softest of the soft spots, there was some hardening; American Woolen Co. also raised prices on 14 of its woolen-type fabrics for women's wear. In short, some industries had already gone through their own private recession and were getting back to something like normal. Actually, a good deal of the buying slump had come because manufacturers were using up their inventories while waiting for prices to settle; once the inventories were gone there would be a new rush...
