Safer Eating through Cloning?

A rather unconventional approach to safeguard consumers against exposure to so-called mad cow disease: Scientists are working to clone cattle that are immune to the disease. Three different teams are working on the project; one of the teams, based in Korea, already has announced the birth of four “mad cow-proof” calves.

Researchers at Virginia Tech hope to have a cloned cow either late this year or early next year.
