No risk seen in mad cow gene tweak
From Times Wire Reports
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 the people who eat them or use products made from them.
