Mad cow's human toll: the unfolding mystery of prion disease and its ultimate casualties

Article Abstract:

Little is known about prion diseases such as mad-cow disease, or bovine spongiform encephalopathy, but the increased number of cases has led to more research to prevent transmission or attempts to create a simple diagnostic tool. The research efforts are described.

The ultimate blood test

Article Abstract:

A company named Biophysical250, which offers 250 blood tests on two tablespoons of patients blood at once at the cost of dollar 3,400 is reviewed. Biophysical250 could uncover a presymptomatic, potentially fatal disease that physicians might not ordinarily test for, but screens only for treatable ailments and avoids those that are invariably fatal such as neurodegenerative conditions as Alzheimer's disease.
