...detect DNA and RNA, the Army team used acridine orange, a fluorochrome dye that easily unites with the nucleic acids and shines brightly under ultraviolet light. Result: the higher the cell's nucleic acid content, the more intense the fluorescence (green to yellow for DNA, red for RNA). After a few hours of training, a skilled cyto-technologist can spot malignant cells by the intensity of fluorescence he sees in his microscope...
...predictable. First came refinements of the stereotactic apparatus which plots a point inside the patient's skull in three dimensions. Then an elaborate technique was developed. In stage one, the surgeon drills a small, carefully plotted hole in each side of the skull to permit injection of dye for making detailed brain X rays. After two or three days comes stage two: another hole is drilled higher up in the skull, and the surgeons insert an insulated steel wire through three inches of brain until its thickened electrode tip lodges in the thalamus. The outer end is anchored...

A tracking beacon, two-way radio, flashing lights, sofar bombs (for underwater sound) and dye markers will guide search parties...

Since U.S. housewives want orange oranges, the Florida orange industry turns green oranges yellow by exposing them to ethylene gas, then colors them orange with a coal-tar dye called...
