After 6 years of study, the FDA has ruled that cloned meat and milk are safe for human consumption. Still, don't expect to see cloned food at your local supermarket any time soon: cloning is expensive, and cloned animals are much more likely to be used for breeding than for eating. For now, anyway.

"Meat repeat: would you eat cloned meat?"

American universities (including University of California, San Francisco) are trying to create stem cell lines using cloned human embryos. (This is what South Korean researchers claimed to have done in 2004 and 2005; the lab later admitted that they'd fabricated their research.) Check the NPR story on who's in the business, how they're paying for it, and what the ethical issues are.

On Wednesday, a group of scientists from Seoul National University unveiled a black and white Afghan hound named Snuppy that is genetically identical to its three-year-old "father."

Snuppy is the result of a process that involved transferring 1,095 canine embryos into 123 surrogate mothers. Only three successful pregnancies occurred. One foetus miscarried but two others were delivered; Snuppy was born on April 24 and his "brother" died from pneumonia after 22 days.

Snuppy is the latest in a series of animal cloning attempts since Dolly, the sheep cloned in 1997. Researchers have since cloned mice, cats, goats, pigs, mules, horses and deer. Dogs, however, are the most challenging of all mammals to clone, because it's difficult to acquire mature eggs. Snuppy's success makes many scientists believe that they have most of the key techniques necessary to clone humans.

The response to Snuppy? Anti-cloning activists are pushing even harder for a worldwide ban on human cloning. "Because this again shows that reproductive cloning is unsafe and inefficient, we call for a worldwide ban on human reproductive cloning, which is also unethical," says Gerald Schatten, at the University of Pittsburgh School of Medicine. Others feel optimistic that Snuppy's creation brings medicine one step closer to finding breakthrough treatments for currently-incurable human diseases. "Bring me human eggs, the necessary social consensus and legal permission and I can get you your replica within a year," said Park Se-Pill, a senior researcher of Maria Biotech and a top cloning expert.

Many diseases, for example, like diabetes, cancer, heart ailments, and problems in hips and joints, are similar in dogs and humans.
