Wiles says his major accomplishment in almosttwo years as Cambridge's lab animals commissionerhas been to implement carbon dioxide asphyxiationas the method of euthanasia for small rodents.Before, Wiles says, many researchers were usinganother, less humane method of killing mice andsmall rats...
Capt. Robert Fennessy, who works in theenforcement division of the Massachusetts Societyfor the Prevention of Cruelty to Animals (MSPCA)said he would rather see the carbon dioxidemethod, if only because it is "more aestheticallypleasing...
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...
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...
