This effect of the environment in the gut on the normal flora is readily recognized. For example, when breast feeding is replaced by solid food the character of the stool changes dramatically, as lactic acid bacteria (which produce sweet-smelling products) are replaced by E. coli and other foul organisms. Early in this century Mechnikov romantically hoped to promote longevity by supplying lactic acid bacteria, in the form of yogurt, to displace the presumably toxic foul organisms. The experiments were a dismal failure, but the commerical success is still seen...
...iron bars to smash the frozen coal loose from rail cars. "It's absolutely miserable work," said Detroit Edison Co. Vice President Walter J. McCarthy Jr. Strapped for fuel, his firm at one point was turning out only 250,000 kilowatts, less than one-tenth of its normal production. At one Cincinnati plant, the slippery coal would not stick to conveyor belts. Ingenious employees devised a solution: spreading molasses on the belts...
After experiencing the coldest November in 66 years, Delaware endured a below-normal December and seemed headed for its most frigid January in history. The state's electricity consumption reached an alltime winter high. Home TV pictures shrank slightly in the Baltimore area when voltage was cut by 5% to conserve energy. Maryland woods were sprinkled with thousands of dead birds, which were unable to penetrate the icy snow to reach food. Stores were running out of rock salt to melt ice, but elderly women found a substitute to steady their steps on sidewalks: a scattering of kitty litter...
Namias and other meteorologists agree on the immediate reason for the bitterly cold weather. The high-level westerly winds-including the jet stream-that whistle through the upper atmosphere high above the U.S. have been circulating in an unusual pattern. Normally in winter these winds flow more directly across the country from west to east. This winter they are cutting across the Rockies much farther to the north than usual and then, as they head toward the East Coast, dipping much farther south than normal...
What triggered these changes, however, remains unclear. Namias notes that water temperatures in the Pacific rose a few degrees higher than normal last fall off the west coast of North America, while dropping off in midocean. He believes that these temperature shifts influence the winds and determine the course of storms that work their way up to the jet-stream level. Harry Geise, a California meteorologist, blames the storms and frigid temperatures on a high-pressure zone of warm air hovering off the country's Pacific coast and sometimes shifting over land...
