...Diana Nyad came ashore last week in Jupiter, Fla., the first person ever to swim from the Bahamas to the U.S. "I feel like the F train in New York just ran over me, but emotionally I'm exhilarated," exulted Nyad between sips of champagne and whiffs of oxygen. The marathoner attempted the feat three weeks ago, but gave up after being stung by a Portuguese manofwar; this time she sprayed herself with latex, "prayed to the Portuguese man-of-war god," and proceeded to finish the 89-mile swim in 27 hrs. and 38 min. Now she will...
Precise details of the process are state secrets, but the general outlines are known. To extract the oil, the Sasol plant burns coal with oxygen and steam in a big cylindrical vessel until a gas forms above the ashes. Once the gas is cleaned of impurities-yielding valuable chemical byproducts in the process-it is mixed with a catalyst made of iron and other substances. This catalyst transforms the gas into liquid oil. Production costs amount to $17 per bbl. That is well below the OPEC price of around $20 per bbl. and much less than...
...distorted his judgment (as E.E. Cummings put it, "Punished bottoms interrupt philosophy"), but Ober believes that the poet's problems began during the first moments of his life. He recalls Swinburne's own statement about having been born "all but dead," and diagnoses brain damage due to oxygen deprivation. Further circumstantial evidence of neuropathology included the poet's small body and outsized head, his tics and excessively nervous temperament. But his talent was not impaired. Neither was his critical acumen, at least when applied to the works of the Marquis de Sade, who was, wrote Swinburne, "like...
...effects can be dramatic. Less blood is available to deliver oxygen to the brain. The heart must pump faster. For anyone with cardiovascular problems, long immersions in hot water can be especially dangerous. If the bather also imbibes-an all too common practice-the alcohol will increase the strain on the heart, and affect the heat-regulating mechanisms in the brain as well. Besides damaging the heart and brain, excessive heat can also cause irreversible harm to the liver and kidneys. Unless bathers get out of the hot tub and replace the lost fluid, they will feel tired. Sometimes they...
...large hydrogen bubble that formed in the reactor vessel. Despite that small explosion, investigators now believe there was never any danger of a bigger blast, which could have ruptured the reactor vessel and containment building, spreading deadly radiation. The false alarm was caused by incorrect speculation about free oxygen in the vessel...
