...blast, but the Viking's preset gyro instruments steer it by moving the whole rocket motor, playing the gas blast from side to side like water from a hose. After the fuel is gone, and the rocket is moving in the last of the atmosphere, small jets of nitrogen shot out of a pressure sphere keep it flying true. The proving of this new system, potentially superior to that of the V2, is the most important work being done with the Vikings. Altitude records, though nice to crow about, are secondary...

Even today, Dr. Codellas points out, the pellets would "merit respect" on a "nutritional and utilitarian" basis. The honey gives carbohydrates, and, with the sesame oil, takes care of caloric values. Protein from the sesame supplies the nitrogen need of the body, the squill serves as a mild heart stimulant, and the opium deadens the stomach's hunger pains...

Known as the "Blue Lupine Queen," Miss Myrick can challenge the "Kudzu Kid" any time. Blue Lupine, incidentally, is a nitrogen-bearing plant used extensively for winter cover crops in the South ... It stops erosion, and adds millions to the income of Georgia farmers...

...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...

Such work is slow and expensive: nitrogen 15 costs $1,000 for a single study. But already Dr. Brown's group have had one outstanding, success in their study of a cell's reproductive system. They used an artificial compound called 2,6-diaminopu-rine, not yet isolated in nature, which they thought had a momentary existence inside the cell. The organic chemists synthesized some of this compound and turned it over to the chemotherapists. They thought that it might have the sought-for "differential effect" on lawless cancer cells...
