Maybe engineers and designers should get Olympic medals. In the pole vault, heights jumped 30% with the switch from bamboo to fiber-glass and carbon- composite poles. Tracks have been resurfaced to give runners more bounce and speed, and pools have been designed to dampen wave action that buffets swimmers. Some athletes fear their events could become contests of equipment and facilities, but as any coach would admit, it still takes a great swimmer to bring out the best in a great pool...
...good reason to issue the new rules. More than 20 years after the government began requiring annual emissions tests for many cars, half of the smog and 90% of the carbon monoxide in the air still pours out of tail pipes; the rest comes mainly from the smokestacks of factories and oil refineries. The new regulations could reduce smog-producing emissions and carbon monoxide pollution from vehicles by 30% in many cities. But repairs to pass the test could cost drivers from $25 to $450, a stiff increase from the present average of $50 to $75. (Anyone whose car still...
...ticket. A secondary law often has been to delay the announcement so as to inject suspense into an otherwise bland convention. Bill Clinton shattered both precepts. Four days before the opening of the Democratic Convention he chose, of all potential running mates, the one closest to being a carbon copy of himself: Tennessee Senator Al Gore. Besides hailing from neighboring mid-South states and swimming in the centrist mainstream of the party, they are close enough in age (Clinton is 45, Gore 44) to form the first all baby-boom ticket...
Since the Industrial Revolution, gases like carbon dioxide and methane have been wafting into the atmosphere, where they let the sun's rays in to warm the earth but keep excess heat from escaping back into space. Acting like the glass walls of a greenhouse, these gases have forced the planet's temperature up 0.8 degreesC (1.5 degreesF) over the past century or so. If the trend continues, temperatures could increase up to 5 degreesC (9 degreesF) within 50 years, raising the sea level, distorting weather patterns and causing widespread environmental disruption...
These spherical, 60- and 70-atom carbon molecules are named after Buckminster Fuller, who popularized the geodesic dome they resemble. They've never been seen outside the lab -- until now. Geologists tracked down buckyballs in the wilds of Russia in an unusual, ancient, carbon-rich rock near the town of Shunga, close to the Finnish border...
