Mad cow disease and other related brain disorders may be caused by a virus and not the weird, misshapen proteins, known as prions, that scientists think are responsible, according to a study released Monday.
Researchers reported that they found virus-like particles in mouse nerve cells infected with two brain-wasting diseases similar to mad cow disease, but found no traces of the particles in uninfected cells.
