While the debate over cloning heats up, researchers have a mystery to unravel: The death of a cloned cow in Tennessee.
The Jersey cow, named Millie, was found dead in its pasture at the University of Tennessee's Experiment Station in Knoxville, nine months after it was born, according to this news service story in the Seattle Times.
An examination of the remains showed no abnormalities except for the size of one kidney.
While the cause of Millie's death is investigated, the debate over the ethical and moral considerations of cloning continues. This story in the Los Angeles Times says the U.S. Food and Drug Administration is considering regulating cloned animals.
The agency has asked biotech firms to make sure that no cloned animals or their products, including milk, enter the food chain.
