...urine. Because urine is formed by the kidneys and passes through the ureters, bladder, urethra and, in males, the prostate gland before it is excreted, it contains cells sloughed off from all of these organs. To determine if any of those cells are cancerous, Sternheimer stains them with two dyes: a blue coloring that attaches itself to the nucleus of diseased cells and a red coloring that combines with all cell components. The malignant cells are not only differentiated by color but by the rate at which they take up the dye; they become stained before healthy cells do. Sternheimer...
Doctors had recently discovered that sores caused by the herpes simplex viruses could be cleared up quickly if they were painted with a photoactive, or light-sensitive dye, then exposed to fluorescent light (TIME, July 12, 1971). But new research with animals suggests that people with herpes might do better to avoid such treatments. Although the dyes, which have not been approved by the FDA, can reduce the infectiousness of herpes viruses, they may produce potentially deadly changes as well. In tests on hamster cells, the dyes apparently caused changes in the viruses that enabled them to transform normal cells...

The girl, her leg still swollen with its two weeks of fracture...

Though he grew to only 60⅜ inches and had to dye his hair red, Jack strutted through life indulging in "imitation Irish ultimating" (like his 6 ft. 3 in. father), gloriously using the world as his straight man. "An Irishman," Jack concludes, looking back to lost innocence, "can get by with things another...
