With tons of soft tissue on ice, geneticists have no shortage of mammoth DNA to play out their fantasy: tweeze a bit of it out, insert it into the ovum of an elephant--a close living cousin--and implant the embryo in the elephant's womb. Before long, a woolly bundle should appear...
That's the hope, but it's a long shot, since even frozen DNA tends to deteriorate over time. "No matter how well preserved old DNA looks," says biologist Rob DeSalle of the American Museum of Natural History in New York City, "it's probably...
Just when you thought you'd heard just about everything about gene research - scientists have supposedly isolated every predisposition from breast cancer to sugar addiction - a group of California doctors claim to have found the DNA strand responsible for the industrialized world's number one killer, heart failure. In a report released Thursday, the team of UC San Diego doctors told of mating mice genetically engineered to contain the gene phospholamban, or PLB, which they believed was responsible for heart failure, with mice that lacked the PLB gene. The resulting offspring did not develop heart failure. They also created mice...
Then came the Jurassic Park rumors. Larry Agenbrod, a Northern Arizona University mammal expert working on the excavation team, said he had been approached by U.S. cryogenics firms interested in cloning the mammoth by combining elephant DNA with DNA extracted from the mammoth remains...
...While many find fault with this hypothesis - the skull is a lone example and does not contain the correct matter for carbon-dating - anthropologists around the world agree that decisive evidence of the skull's geographic ancestry will be produced by testing its DNA and comparing it to that of other Negroid peoples, such as Australian aborigines and Africans. The remains of the woman who's spawning the debate, nicknamed Luzia, were found in 1975 outside Belo Horizonte, Brazil's third largest city, and were in storage in a Rio museum for a quarter of a century. That sound...
