Doctors told him it was Alzheimer’s, but Singeltary was suspicious. The diagnosis didn’t fit her violent symptoms, and he demanded an autopsy. It showed she had died of sporadic Creutzfeldt-Jakob disease. Most doctors believe that sCJD is caused by a prion protein deforming by chance into a killer. But Singeltary thinks otherwise. He is one of a number of campaigners who say that some sCJD, like the variant CJD related to BSE, is caused by eating meat from infected animals. Their suspicions have focused on sheep carrying scrapie, a BSE-like disease that is widespread in flocks across Europe and North America. Now scientists in France have stumbled across new evidence that adds weight to the campaigners’ fears. To their complete surprise, the researchers found that one strain of scrapie causes the s
