SHOVE THIS! Fiber-optic colonoscopes are better than barium enemas in detecting colon cancer...
...double-contrast barium enema, a technician coats the inside of the intestine with the metallic dye and pumps the colon full of air. Then an X ray of the large intestine is taken, allowing doctors to visualize the outline of most abnormal growths. Provided the colon is clear, a barium enema should be repeated every five to 10 years. Cost...
...carry a government health warning? A piece being displayed at New York City's New Museum of Contemporary Art could have used such a caveat. When Eclipse of the Earth by Kazuo Katase was installed last month, the work's dusty red coloring agent contained zinc sulfide and barium sulfate. The chemicals caused severe respiratory and skin problems for some employees, they claim. A staff memo admitted that "ingestion of the pigment will cause illness, and the inhalation of the dust is known to cause lung irritation." Although the powder was replaced 12 days later, three workers resigned...
...Force to stage the $250 million fireworks display, but they promise it will be well worth the price. During the next two weeks, a team of scientists is planning a dazzling light show as part of a project to study the earth's magnetic fields. Fourteen canisters containing barium and lithium will be released from a satellite orbiting as high as 20,000 miles above the earth, creating a display of luminous red, green and purple clouds over much of North and South America, the Atlantic and Western Europe. Scientists hope that by monitoring the movement of the clouds, they...
...time for more wild thinking. Chu reasoned that the high pressure worked because it squashed the compound's molecular structure and that this somehow boosted its superconducting temperature. Since more pressure did no good, Chu decided to compress the molecules in a different way -- from within. He replaced the barium with strontium, which is similar chemically but has a smaller atomic structure. Sure enough, the temperature rose again, to 54 K, then stopped. So he turned to calcium, an element with even smaller atoms. This time the temperature dropped. It appeared to be a dead...
