...what hath Wilmut wrought? A fully formed, perfectly healthy mammal--a mammal!--born from a single adult cell. Not since God took Adam's rib and fashioned a helpmate for him has anything so fantastic occurred...
...recent years, some scientists have speculated that the changes wrought by differentiation might be irreversible, in which case cloning an adult mammal would be biologically impossible. The birth of Dolly not only proves them wrong but also suggests that the difficulty scientists have had cloning adult cells may have less to do with biology than with technique...
...DIEGO: A neurobiologist in California has found a way to implant the natural behavior of one animal into an entirely different species. The breakthrough, published in the Proceedings of the National Academy of Sciences, comes just a week after scientists stunned the world by cloning an adult mammal and further demonstrates science fiction's uncanny knack for becoming reality. In the experiment, a chicken was made to act like a quail by transferring certain brain cells from a quail embryo to the brain of a chicken embryo. Once hatched, the chicken's movement's resembled those of a quail...
...announcement which has left both the scientific and ethical communities aghast, a researcher working for a private company in Edinburgh, Scotland, has apparently created the first successful clone of an adult mammal--a ewe, genetically identical to a six-year-old adult sheep...
...YORK: An unsettling bit of science fiction crossed over into reality Monday morning in the form of Dolly, an embraceable ewe with an incredible past: She was an exact genetic copy of another lamb. News of the first-ever cloning of a mammal sent stock in the small Scottish biotech company responsible soaring as investors drooled (whole herds of the same prizewinning cow!) over the possibilities. More cautious types pointed out that this procedure could presumably, uh, be used to make copies of humans, which opens up an extremely large ethical can of worms. Ian Wilmut, one of the scientists...
