...scientists' basic strategy was the same as in most post-Dolly cloning experiments: remove the nucleus of the egg, with its single set of chromosomes, and replace it with the nucleus of a mature cell, containing two sets (in this case, the mature nuclei came from cumulus cells, which surround eggs during development). With a quantity of eggs that a commentary in Science calls "whopping," the scientists were able to experiment with different techniques to find which worked best--varying the time between inserting the new nucleus and zapping it with electricity to trigger cell division, for example, or testing...
...away, the most addictive programming on C-SPAN was the FCC hearings. I watched Lewis Dickey, chair of Cumulus Entertainment—a villain in the classical mold, clear blue eyes and smug jaw—say that he did not force his local affiliates to ban the Dixie Chicks, that he called them and told them to do it, but it was something that they would have wanted to do anyway. I, of course, at 1:30 in a pitch black night, dressed in an oversized striped T-shirt and lounging on the couch drinking cranberry juice, heckle...
...didn't notice the bridge until we were almost upon it. We came out of a cumulus of red dust to find ourselves whizzing between massive stone balustrades over a yawning gorge. At 85 meters, Spean Praptos is the longest surviving bridge from the Angkor era. "That bridge has been standing more than 800 years," said Mony, who works for the government's conservation authority, Apsara. "My ancestors built roads and bridges that were just as impressive in their way as any of the temples...
...cells from the animal's mouth and fused them with cat-donor eggs that had been emptied of genetic material. This created 82 embryos, which were implanted into seven surrogate mothers. The process yielded only a single fetal clone, and that one died in utero. Researchers then turned to cumulus cells from the ovaries of a female named Rainbow, creating five cloned embryos. These were implanted in Allie, another surrogate, and this time an embryo took hold and grew. The result was cc, born Dec. 22 and announced with a flourish last week by the journal Nature. "It was very...
...models still aren't perfect. One major flaw, agree critics and champions alike, is that they don't adequately account for clouds. In a warmer world, more water will evaporate from the oceans and presumably form more clouds. If they are billowy cumulus clouds, they will tend to shade the planet and slow down warming; if they are high, feathery cirrus clouds, they will trap even more heat...
