Scientists now have found the astonishing hint that the thhing you've called "cow desease" (Creutzfeld-Jakob-Desease) might have something to do with a kind of failed wake.-up from winter rest (what we call "Winterschlaf" in German), because the proteins found to be causing this, were also found in animals making the deep winter rest or winter sleep.
Therefore, the scienticts are puzzled what's actually going on there.
