...vital gas being destroyed is a form of oxygen in which the molecules have three atoms instead of the normal two. That simple structure enables ozone to absorb ultraviolet radiation -- a process that is crucial to human health. UV rays can make the lens of the eye cloud up with cataracts, which bring on blindness if untreated. The radiation can cause mutations in DNA, leading to skin cancers, including the often deadly melanoma. Estimates released last week by the United Nations Environment Program predict a 26% rise in the incidence of nonmelanoma skin cancers worldwide if overall ozone levels drop...
...there for nearly a week, depriving all candidates of the chance to promote issue-oriented messages. Said former Democratic Party chairman John White: "Your first instinct is to think there's an opening, but other candidates were really disadvantaged by this trash too. It just sucked up all the oxygen in the room." Co-anchor Cathy Burnham of the state's leading television outlet, WMUR, wryly acknowledged that fact last week as she introduced a story on Senator Bob Kerrey's health-care ideas. "And now," she said, minutes into the newscast's political coverage...
...their flight, they let out a fine mist of gas behind them, for, say, a mile. Then, they blow and set all that mist on fire. The explosive effect is the equivalent of a small nuclear weapon, without the fallout, and the bombs suck all the nearby oxygen...
...genetic legacy of sex differences has already been rendered moot by that uniquely human invention: technology. Military prowess no longer depends on superior musculature or those bursts of hormones that prime the body for combat at ax range. As for exploration, women -- with their lower body weight and oxygen consumption -- may be the more "natural" astronauts...
Using powerful new tools, biologists at the University of Chicago have gently sliced through a red blood cell to peer at individual protein molecules clinging to its inner membrane. At the California Institute of Technology, chemists have watched in wonder as a hydrogen atom romances an oxygen away from a carbon dioxide molecule. And at Stanford University, physicist Steven Chu has mastered techniques for levitating millions of sodium atoms inside a stainless-steel canister and releasing them all at once in luminescent fountains. Of late, Chu and his colleagues have amused themselves by stretching a double-stranded DNA molecule...
