What is going on? Scientists have a standard reply to questions like this. It is the nature of weather, they say, for wild fluctuations to occur. Their proof: there is a record broken every day somewhere in the world. But after last week's weather -- which showed every sign of being this week's weather as well -- the standard reply starts to wear a little thin. Why are so many records being set in so many places right now? Could it have anything to do with the holes we've drilled in the ozone layer? The forests we've leveled...
...global warming -- even if a few privately suspect it to be so. The theory that the buildup of CO2, methane and other heat-trapping gases can raise global temperatures -- like the glass in the walls of a greenhouse -- is well established, but no one knows how much warming will occur or how soon. While early computer models suggested that average global temperatures could jump 3 degreesF to 9 degreesF by the middle of the next century, recent studies have cast doubt on those estimates. Even a small change in average temperatures can trigger big changes in local weather patterns...
...again later in life, producing shingles, a painful skin rash. The vaccine is a weakened form of the virus, and it too may be harbored in the body forever. The debilitated virus could conceivably spring to life years after the vaccination, and no one knows what damage might occur. Another danger is that the vaccine may not confer lifelong immunity and will therefore make a person vulnerable to chicken pox during adulthood, when the disease can be more serious. "It's impossible in the experimental studies preceding licensing to study a vaccine's effects for 50 years," says Dr. Caroline...
Another facet of her secret is sheer vitality. There is great energy in her step; when she enters a room, she makes an immediate impact. She radiates health, and for good reason. She still rides, swims regularly and is an implacable hiker. The hikes occur at her country estate in Middleburg, Virginia, and at her spread in Sun Valley, Idaho. That's where she goes to relax (always accompanied by legions of houseguests...
Many things could delay the renovation--freak accidents, unforeseen glitches, labor strikes, shoddy workmanship. Harvard Real Estate and College officials know, though, that if a major delay does occur, they will most likely end up having to explain it to the national media, as well as to parents and alumni...
