...able to determine whether DNA in the nuclei of both animals' cells is identical--the first hallmark of a true clone. Ian Wilmut, the Scottish scientist who created Dolly the sheep in 1996, had to provide such samples to prove to skeptics that he had created history's first mammalian clone...
...Broad Institute have mapped the genes of man’s best friend, the dog, in the hopes of uncovering insights into diseases that affect both humans and canines. The results, published in the December 8 issue of the science journal Nature, include the first comparative analysis of three mammalian genomes—human, mouse, and dog. Tarjei S. Mikkelsen, a graduate student at the Harvard-MIT Division of Health Sciences and Technology (HST) and one of the leaders of the research project, said that researchers were surprised that the sequences that humans had in common with dogs were...
...quest to duplicate a dog been something of a Holy Grail in the tricky field of mammalian cloning. Since Dolly the sheep was cloned in 1996, scientists have followed with pigs, cattle, mice, rabbits, horses and cats. But though they tried mightily, nobody had ever created a genetic double of man's best friend. Not, that is, until South Korean researcher Woo Suk Hwang and his team at Seoul National University brought Snuppy the puppy into the world--an animal whose entire genome came from a single cell from the ear of a three-year-old Afghan hound. Snuppy...
Ever since the 1970s, when scientists first learned to snip individual fragments from the hundreds of thousands of genes in the nuclei of mammalian cells, the behavior of the isolated segments interacting with cells in a laboratory dish has been studied extensively, an approach with obvious limitations. "A new gene in cell culture can't walk funny or think strange thoughts or do what it had planned to do," says David Baltimore, director of the Whitehead Institute and a Nobel-prizewinning biologist. "You need to trace its course through a living, breathing organism...
...None of that, though, changes one irksome fact that has limited Wu's business. For all their gastronomic enthusiasm for endangered sea animals or all matter of rare mammalian life, the Chinese so far appear immune to the pleasures of a black truffle. Mushroom gatherer Li Kun shakes his head when asked whether he enjoys the flavor of the black nuggets he's scooping up from the loamy soil near Hama. "When we're really hungry, we eat them covered with soy sauce, coriander, chili paste and MSG," he says. "That way you don't have to taste the truffle...
