Some 330,000 German nationals found U.S. borders closed to any exodus. The State Department had no intention of allowing Nazis to filter into Mexico and South America and operate from there against the U.S. Furthermore, they might come in handy as hostages to guarantee the safety of U.S. nationals in Europe...
...main system was completed in 1939. Finished last week were 150 more miles of distributing lines which pipe the water from the filter plant (capacity: 1,000,000 gallons a day) near Riverside to the reservoirs of Santa Monica, Beverly Hills, Long Beach, Santa Ana, nine other cities. As the sweet waters of the far-off Colorado slowly welled up last week into a subterranean chamber supplying Sunset Reservoir, Pasadena became the first community in the system to get the District's water...
...called bacteriophage. Strains of bacteriophage are found in the human intestinal tract, in urine, pus, blood and sewage. About 25 years ago, bacteriophage was first isolated by a British scientist from a dead germ colony. The mysterious substance that killed the bacteria was able to pass through a fine filter and infect other colonies. Some doctors soon dreamed of it as a universal panacea. (Sinclair Lewis dramatized this hope in his novel Arrowsmith.) Compared to the early days, the claims last week seemed conservative...
Scientists long knew that viruses caused smallpox, influenza, yellow fever, infantile paralysis, many other human, animal and plant diseases. But since they could neither see nor filter out viruses, scientists assumed that they were living, submicroscopic organisms. In 1935 Stanley showed that a pure strain of virus could be crystallized-consisted of lifeless molecules with the curious, lifelike power of reproducing themselves. This discovery closed the mysterious gap between living and inert matter, indicated no essential distinction except relative complexity of structure between atom, molecule, virus, cell and multicellular organism such...
When Der Tag came, Metaxas let the Italians filter through mountain passes almost to loannina; then sent his Evzones, born mountaineers, trained in the manner of German Alpine troops, against them...
