...high altitudes, where cosmic ray effects are strongest). Their authorized, translated report is far from clear, but apparently they found what they were looking for in the sensitive emulsion: groups of short lines arranged like a star or a chicken-track. Each of these, they said, was an X which marked the spot where a negative meson had murdered an atomic nucleus...
...experts, some of whom had solemnly verified the forged Vermeers, were now at work with their biggest X-ray machines and subtlest chemicals to prove Van Meegeren a fraud when his case comes up next month (although The Netherlands Government's information service has already said that "there can be no doubt that this mad genius did paint the seven pictures attributed to Vermeer...
...species. Scandinavian scientists may have recognized this last week when a committee of them awarded the Nobel Prize in medicine and physiology to 55-year-old Professor Hermann J. Muller of Indiana University, leading authority on radioactive mutations. Nearly 20 years ago he discovered that fruit flies treated with X rays produced "mutated" (changed) offspring. The discovery made him famous among biologists, but the general public never took it personally. No one dreamed that in less than a generation the human race might be treated with X rays, and mutate...
Every human being is constantly subjected to bombardment by gamma rays (X rays) from natural sources such as cosmic rays. These do no visible damage, for the body is accustomed to the low normal "level of radiation." But when a gamma ray hits the nucleus of a spermatozoon or ovum (the reproductive cells which unite to form a new individual), it may damage one of the thousands of "genes" which carry hereditary characteristics from one generation to the next. This may produce a "mutation." The child may differ slightly or radically from its parents, or the difference may lie concealed...

(One Manhattan store, with perfect justification, used a reproduction of John Singer Sargeant's 1884 Portrait of Madame X as an index to current style.) While the thrill lasted, U.S. women were going to be taken out and admired-if their husbands could find a tuxedo, that...
