...faulty valve on a pressurized gas canister caused a leak of hydrogen chloride gas--a highly corrosive substance used for etching--at Conant Laboratory Monday evening, forcing its occupants to evacuate the building...
...Crimson racquetmen engaged in their own version of guerilla warfare as they defeated Army in a 9-0 shellacking. The matched resembled nine hydrogen bombs lined up against nine water pistols...
...have now been shut down. They are the pioneering Hanford facility in Washington, where eight reactors have been deactivated and the remaining one is on indefinite standby; the Savannah River complex, where all three operational reactors are down, knocking out the only means of producing tritium, a hydrogen isotope that boosts the explosive power of nearly all the 22,000 U.S. nuclear warheads; the plutonium-processing plant at Rocky Flats near Boulder, Colo.; and the deceptively named Feed Materials Production Center, in Fernald, Ohio, where some workers are striking for higher wages and safer conditions...
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...
...computer-enhanced photograph shows the galaxy as a brightly colored, amoeba-shaped mass. Next, the scientists determined the distance of the galaxy by taking an optical spectrum that revealed what one team member, Kenneth Chambers of Johns Hopkins University, calls cosmic fingerprints -- emission lines with sharp features characteristic of hydrogen and carbon. In distant galaxies, these lines occur at much redder wavelengths than those emitted by the same elements on earth; this so-called red shift, believed to be caused by the expansion of the universe, is what astronomers use to measure distance...
