...Uncasville, Conn.? Answer: they form a healthy environmental equation. That is the hope of Virginia-based Applied Energy Services, a builder and operator of power plants in Texas, Pennsylvania and California. Like any other coal-fired generator, the 180-megawatt plant now under construction in Uncasville will spew carbon dioxide, the chief culprit ! in the globe-warming greenhouse effect. But acting on a recommendation from the World Resources Institute, a Washington environmental-policy research center, AES has voluntarily donated $2 million in seed money to a CARE project in Guatemala designed to stave off the climatic crisis by replanting depleted...
Ballestrero had initially agreed to an extraordinary series of scientific tests on the shroud in 1978, but refused to permit carbon 14 testing, which was crucial to determining the fabric's age. Handkerchief-size samples needed to be cut out, which, to Ballestrero, was unthinkable for such a revered historical item. After technical improvements made it possible to use samples the size of postage stamps, however, the Cardinal allowed cuttings to be taken last April...
...done simultaneously at the University of Arizona, Britain's Oxford University and Switzerland's Federal Institute of Technology in Zurich. Each laboratory received four unmarked samples: a shroud cutting and three control pieces, one of which dated from the 1st century. The samples were chemically cleaned, burned to produce carbon dioxide, catalytically converted into graphite and then tested for carbon 14 isotopes to fix the date by calculating the amount of radioactive decay. Only London's British Museum, which coordinated the testing, knew which samples were which...
Thursday morning, as I sat in front of the television watching NASA technicians worry the Discovery through its countdown, I ate a star for breakfast. The star was in the form of a waffle. It consisted mostly of carbon, nitrogen, oxygen and hydrogen, with a sprinkling of other elements. Except for the hydrogen, those atoms had been forged in a star that exploded and died long before our sun and solar system were born. The hydrogen was made in the big bang that allegedly began the universe. Some astronomers think that it was on dust grains floating in interstellar space...
Currently the most pressing and complex environmental problem is the greenhouse effect. The industrial age has been fueled by the burning of coal, wood and oil, which spews wastes -- most notably carbon dioxide (CO2) -- into the sky. This thickens the layer of atmospheric gases that traps heat from the sun and keep the earth warm. This greenhouse effect is expected to bring about more change more quickly than any other climatic event in the earth's history. Scientists warn that the changes cannot be stopped, though they can be slowed. But the time is short. Says Robert Dickinson, a senior...
