...open grasslands and the charm of Mongolian nomads and herders. And soon even those delights may be hard to find. Despite the grandeur of the desert landscape, it is impossible not to notice the growing environmental catastrophe. Countless hills and rangelands are giving way to erosion, as millions of sheep and goats eat the sparse vegetation and lay the ground bare. In the end, the region's very remoteness may be its downfall?so few people get there to revel in its unique beauty that few are protesting its passing...
...took the first steps in that direction by two different techniques. In one, they stimulated an unfertilized egg to begin dividing on its own. In the other, they removed the nucleus from a donated egg and inserted that of an adult--the same method used to produce Dolly the sheep, the world's first mammalian clone...
...mainstream medical community is skeptical of Antinori's claims and takes a more moderate view of the issue. "There is a need for careful discussion and debate about human reproductive cloning," says Harry Griffin, assistant director at the Roslin Institute, where Dolly the sheep was cloned in 1997. But, he said, anyone who insists on reproducing themselves "needs counseling, not cloning...
...eight patients in one of the trauma wards are an 18-year-old whose face was crushed when a U.S. bomb destroyed his house, a 10-year-old boy shot by a stray bullet and an angry shepherd named Khan. He says that when he was tending his sheep last week, 25 armed men working for another of the city's commanders, regional security chief Hazrat Ali, drove up and began stealing the animals. He tried to stop them, and they shot him twice in the chest. "This kind of thing never happened under the Taliban," he says...
...were created through a technique known as “somatic cell nuclear transfer,” in which the genetic material of a developed cell (such as a stem cell) is inserted into an egg. The same technique was used by researchers in Scotland to conceive Dolly the sheep in 1997. Though the experiment was far from a success—none of the embryos grew to larger than six cells before dying—it set a precedent for future research that could eventually result in the birth of a child conceived through cloning...
