Genetically-engineered cattle can withstand mad cow disease, says new study (EARTHtimes.org) The genes of cattle can be altered to omit a protein that causes the mad cow disease without any adverse effect on the cattle. Scientists at Hematech Inc., a unit of Japanese company Kirin Brewery Co., and the U.S. department of agriculture found that cows bred without the prion protein were healthy at age 20 months and their tissue showed signs of resistance to the brain-destroying disease ...

No risk seen in mad cow gene tweak (Los Angeles Times) Cattle can be genetically altered to lack the protein that causes mad cow disease without adverse health effects, a study by scientists at the U.S. Department of Agriculture and Hematech Inc. shows. The findings, published on the website of the journal Nature Biotechnology, suggest that genetic modifications can protect cattle from the disease, potentially eradicating the threat to livestock and ...

IN BRIEF: Hopes rise of cutting mad cow danger (The Charlotte Observer) Scientists said Sunday that they have used genetic engineering techniques to produce the first cattle that might be biologically incapable of getting mad cow disease. The animals, which lack a gene crucial to the disease's progression, were not designed for use as food. They were created so human pharmaceuticals can be made in their blood. [News Source]

Scientists create world's first mad cow disease immune cattle (ANI via Yahoo! India News) Edinburgh, Jan 1 (ANI): A team of Japanese and American scientists claim to have engineered the world's first cattle that is immune to mad cow disease. Mad cow disease, or bovine spongiform encephalopathy (BSE), is caused by prions (a vital protein) getting damaged and spreading to the animal's brain tissue. It causes the collapse of the cow's central nervous system. In their study, ... [News Source]
